<p>I'm trying to modify the <a href="https://wordpress.org/plugins/gd-mylist/" rel="nofollow">My Wish List plugin</a> so that I can retrieve some custom fields (I'm using the <a href="https://www.advancedcustomfields.com/" rel="nofollow">Advanced Custom Fields plugin</a> to create my custom fields in the admin end).</p>
<p>The plugin uses the custom query below to pull out specific data, but I want to retrieve each post's custom fields as well in that loop.

No, it is not possible to create third level menu in admin panel. If you look at the definition of **add\_submenu\_page**, you need to mention the parent slug name. **For eg:**
```
add_menu_page ( 'Test Menu', 'Test Menu', 'read', 'testmainmenu', '', '' );
add_submenu_page ( 'testmainmenu', 'Test Menu', 'Child1', 'read', 'child1', '');
```
The first parameter of the **add\_submenu\_page** will be parent slug name. So you may think we can write **child1** as *parent slug name* to create the third level. **Eg:**
```
add_submenu_page ( 'child1', 'Test Menu', 'Child2', 'read', 'child2', '');
```
But this will not work. Look at the parameters definition and source section in this [link](https://developer.wordpress.org/reference/functions/add_submenu_page/). It clearly states that, you can only use the name of '**main menu of the plugin**' or the **file name** of the WordPress plugin in **parent slug name**. So it is not possible to create submenus more than once in admin panel. However, you can create *n* number of sub menus in front end.

<p>I have a simple function, which returns the content of a page with the given pageID:</p>
<pre><code>function get_page_content(){
$id = $_REQUEST['id'];
$page_data = get_page($id);
echo apply_filters('the_content', $page_data->post_content);
//echo do_shortcode($page_data -> post_content);
wp_die();
}
add_action( 'wp_ajax_nopriv_get_page_content', 'get_page_content' );
add_action( 'wp_ajax_get_page_content', 'get_page_content' );
</code></pre>
<p>But after an Update of WP and some Plugins the returned content still containes unresolved shortcodes like so:</p>
<pre><code>[vc_row row_type=“row“ use_row_as_full_screen_section=“no“ type=“grid“ text_align=“left“ background_image_as_pattern=“without_pattern“][vc_column width=“1/1″]
</code></pre>
<p>The shortcodes come from a Plugin called <strong>Visual Composer</strong> (which got updated in the process to the latest version)</p>
<p><strong>Question:</strong>
How can i render the shortcodes befor i return the content?
I tried both</p>
<pre><code>echo apply_filters('the_content', $page_data->post_content);
</code></pre>
<p>and</p>
<pre><code>echo do_shortcode($page_data -> post_content);

I have a simple function, which returns the content of a page with the given pageID:
```
function get_page_content(){
$id = $_REQUEST['id'];
$page_data = get_page($id);
echo apply_filters('the_content', $page_data->post_content);
//echo do_shortcode($page_data -> post_content);
wp_die();
}
add_action( 'wp_ajax_nopriv_get_page_content', 'get_page_content' );
add_action( 'wp_ajax_get_page_content', 'get_page_content' );
```
But after an Update of WP and some Plugins the returned content still containes unresolved shortcodes like so:
```
[vc_row row_type=“row“ use_row_as_full_screen_section=“no“ type=“grid“ text_align=“left“ background_image_as_pattern=“without_pattern“][vc_column width=“1/1″]
```
The shortcodes come from a Plugin called **Visual Composer** (which got updated in the process to the latest version)
**Question:**
How can i render the shortcodes befor i return the content?
I tried both
```
echo apply_filters('the_content', $page_data->post_content);
```
and
```
echo do_shortcode($page_data -> post_content);
```

Since version 4.9 visual composer added shortcode lazy loading. To use VC shortcodes on AJAX content use this function before printing the content `WPBMap::addAllMappedShortcodes();`. So below code may help you,
```
function get_page_content(){
$id = $_REQUEST['id'];
$page_data = get_page($id);
WPBMap::addAllMappedShortcodes();
echo apply_filters('the_content', $page_data->post_content);
wp_die();
}
add_action( 'wp_ajax_nopriv_get_page_content', 'get_page_content' );
add_action( 'wp_ajax_get_page_content', 'get_page_content' );
```

<p>I created page templates that use the page slug, for example, <code>page-contact.php</code>, <code>page-gallery.php</code> etc. or page id, for example, <code>page-2.php</code>, <code>page-11.php</code> etc.</p>
<p>How can I move these templates to a subfolder, for example <code>/mytheme/pages/</code>?</p>

It would be handy if there was a filter to let you inject your additional template into the right part of the template hierarchy, but in the absence of that we'll need to replicate the search for page templates from WordPress's own get_page_template() function, found in /wp-includes/template.php:</p>\n\n<pre><code>function get_page_template() {\n $id = get_queried_object_id();\n $template = get_page_template_slug();\n $pagename = get_query_var('pagename');\n\n if ( ! $pagename && $id ) {\n // If a static page is set as the front page, $pagename will not be set.

I created page templates that use the page slug, for example, `page-contact.php`, `page-gallery.php` etc. or page id, for example, `page-2.php`, `page-11.php` etc.
How can I move these templates to a subfolder, for example `/mytheme/pages/`?
|
/YOUR\_THEME/page-templates/ will only work for custom page templates assigned on the admin page edit screen, not for page-$slug or page-$id named templates.
The correct filter hook in my view is page\_template, but you don't (I assume!) want to throw out any other possible templates for your pages, not least because you're bound to have some pages on your site for which you haven't made a /my-sub-dir/page-$slug.php template file.
The page\_template filter hook is called just after WP has found a template for the page using the standard template hierarchy. It would be handy if there was a filter to let you inject your additional template into the right part of the template hierarchy, but in the absence of that we'll need to replicate the search for page templates from WordPress's own get\_page\_template() function, found in /wp-includes/template.php:
```
function get_page_template() {
$id = get_queried_object_id();
$template = get_page_template_slug();
$pagename = get_query_var('pagename');
if ( ! $pagename && $id ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = get_queried_object();
if ( $post )
$pagename = $post->post_name;
}
$templates = array();
if ( $template && 0 === validate_file( $template ) )
$templates[] = $template;
if ( $pagename )
$templates[] = "page-$pagename.php";
if ( $id )
$templates[] = "page-$id.php";
$templates[] = 'page.php';
return get_query_template( 'page', $templates );
}
```
This function builds an array of possible templates for Pages. get\_query\_template() then uses locate\_template() to run through the array and return the filename of the first template found.
As we can't hook into the list of proposed templates, we'll sadly have to duplicate some of this work.
Here's our own function:
```
function tbdn_get_page_template() {
$id = get_queried_object_id();
$template = get_page_template_slug();
$pagename = get_query_var('pagename');
if ( ! $pagename && $id ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = get_queried_object();
if ( $post )
$pagename = $post->post_name;
}
$templates = array();
if ( $template && 0 === validate_file( $template ) )
$templates[] = $template;
// if there's a custom template then still give that priority
if ( $pagename )
$templates[] = "our-sub-dir/page-$pagename.php";
// change the default search for the page-$slug template to use our directory
// you could also look in the theme root directory either before or after this
if ( $id )
$templates[] = "our-sub-dir/page-$id.php";
$templates[] = 'page.php';
/* Don't call get_query_template again!!!
// return get_query_template( 'page', $templates );
We also reproduce the key code of get_query_template() - we don't want to call it or we'll get stuck in a loop .
We can remove lines of code that we know won't apply for pages, leaving us with...
*/
$template = locate_template( $templates );
return $template;
}
add_filter( 'page_template', 'tbdn_get_page_template' );
```
Caveats:
1 - I haven't tested this, but if you're up to messing around with the template hierarchy then you should certainly be able to follow, test & adjust my code which is mostly copied from WP anyway.
2 - If future core code ever changes the template hierarchy for pages then the code above will go out-of-date.

<p>I'm having issues with images getting badly compressed when uploaded to my site. It's not an issue with photographs, but is very noticeable for images with solid blocks of colour and text.</p>
<p>I've uploaded a PNG with a solid grey background overlaid with white text, and it's being badly compressed when WordPress resizes it to the various alternative sizes.</p>
<p><a href="http://www.wondercompany.co.uk/wp-content/uploads/2016/05/tc1.png" rel="nofollow">Original image</a></p>
<p><a href="http://www.wondercompany.co.uk/wp-content/uploads/2016/05/tc1-1024x682.png" rel="nofollow">Large featured image size</a></p>
<p>Unfortunately I don't have enough reputation to post more than 2 links, but you can see in the resized Large version that the text has become very blurry, and the solid grey background has a noticeable strobe to it.</p>
<p>I know you can turn off / adjust the level of JPG image compression, but as far as I know WordPress shouldn't be compressing PNGs at all, so I'm at a loss to figure out what's going on.</p>
<p>What could be causing this? Is this potentially an issue with the compression / resize software on my server? Or is there a way to tell WordPress not to compress PNGs, like there is with JPEGs?</p>

<p>I'm trying to write a simple permission admin page plugin.
So far I made a page with every role where I can check a certain menu page to be disabled from menu. I simply get <code>global $menu</code> and save to option encoded to JSON array. </p>
<p>Example:</p>
<pre><code> array(2) {
["sub_administrator"]=>
array(11) {
[0]=>
string(10) "menu-posts"
[1]=>
string(19) "toplevel_page_wpcf7"
[2]=>
string(15) "menu-appearance"
[3]=>
string(12) "menu-plugins"
[4]=>
string(10) "menu-tools"
[5]=>
string(13) "menu-settings"
[6]=>
string(32) "toplevel_page_edit?post_type=acf"
[7]=>
string(30) "toplevel_page_bwp_capt_general"
[8]=>
string(40) "toplevel_page_mr_permissions_admin_pages"
[9]=>
string(23) "toplevel_page_Wordfence"
[10]=>
string(28) "toplevel_page_wp-user-avatar"
}
}
</code></pre>
<p>Later using <code>admin_menu</code> hook I remove from display a certain menu item</p>
<pre><code>function mr_permissions_roles_admin_menu_restriction() {
echo'<pre>';
global $menu;
$restricted=array();
$current_user=wp_get_current_user();
$role_restriction=get_option('mr_permissions_roles');
$role_restriction=(array)json_decode($role_restriction);
$role=$current_user->roles[0];
if(!empty($role_restriction[$role]))
{
$restricted=$role_restriction[$role];
}
foreach ( $menu as $item => $data ) {
if ( ! isset( $data[5] ) ) {
continue; // Move along if the current $item doesn't have a slug.
} elseif ( in_array( $data[5], $restricted ) ) {
unset( $menu[$item] ); // Remove the current $item from the $menu.
}
}
echo'</pre>';
}
add_action( 'admin_menu', 'mr_permissions_roles_admin_menu_restriction',20);
</code></pre>
<p>That's the easy part here.</p>
<p>Now I want before every admin page to load check if user has plugin permission to go to page (people still can go to page by url).</p>
<p>I made something that works but not everywhere. I explain under code.</p>
<pre><code>function mr_permissions_roles_admin_page_restriction($screen)
{
global $menu;
$current_user=wp_get_current_user();
$role_restriction=get_option('mr_permissions_roles');
$role_restriction=(array)json_decode($role_restriction);

<p>I found that <code>current_screen</code> hook. Well hook which I wanted but not exactly. For example to post menu item slug is <code>menu-posts</code>. In <code>$screen</code> variable and $menu variable there no single thing I can compare. For custom admin menu pages it works well. $menu slug is in $screen->base so I can compare it. But when it comes to built-in pages it doesn't work. So here are a few questions which may solve my problem.</p>
<ol>
<li><p>How to get admin menu item. Then I can save it in a different way and compare differently.</p></li>
<li><p>Is there any way I can get more data from <code>current_screen</code>.</p></li>
<li><p>Any other ideas?</p></li>
<li><p>(bonus) How can I get submenu pages for example for posts. <code>global $menu</code> doesn't have it. I would like to add to my plugin possibility to disable access to submenu pages (a few of them not all for example)</p></li>
</ol>
<p>I even tried to look into database for any information but couldn't find anything. </p>
<p>I also made a custom page to edit every user to let them add posts to one or few of my custom_posts. So for default Editor have no right to custom_posts. When I want to make someone who will for example add companies (custom_post) I go to users and I check checkbox and save. From now on this user with role editor can edit companies but others editors can't.</p>

I'm trying to write a simple permission admin page plugin.
So far I made a page with every role where I can check a certain menu page to be disabled from menu. I simply get `global $menu` and save to option encoded to JSON array.
Example:
```
array(2) {
["sub_administrator"]=>
array(11) {
[0]=>
string(10) "menu-posts"
[1]=>
string(19) "toplevel_page_wpcf7"
[2]=>
string(15) "menu-appearance"
[3]=>
string(12) "menu-plugins"
[4]=>
string(10) "menu-tools"
[5]=>
string(13) "menu-settings"
[6]=>
string(32) "toplevel_page_edit?post_type=acf"
[7]=>
string(30) "toplevel_page_bwp_capt_general"
[8]=>
string(40) "toplevel_page_mr_permissions_admin_pages"
[9]=>
string(23) "toplevel_page_Wordfence"
[10]=>
string(28) "toplevel_page_wp-user-avatar"
}
}
```
Later using `admin_menu` hook I remove from display a certain menu item
```
function mr_permissions_roles_admin_menu_restriction() {
echo'<pre>';
global $menu;
$restricted=array();
$current_user=wp_get_current_user();
$role_restriction=get_option('mr_permissions_roles');
$role_restriction=(array)json_decode($role_restriction);
$role=$current_user->roles[0];
if(!empty($role_restriction[$role]))
{
$restricted=$role_restriction[$role];
}
foreach ( $menu as $item => $data ) {
if ( ! isset( $data[5] ) ) {
continue; // Move along if the current $item doesn't have a slug.
} elseif ( in_array( $data[5], $restricted ) ) {
unset( $menu[$item] ); // Remove the current $item from the $menu.
}
}
echo'</pre>';
}
add_action( 'admin_menu', 'mr_permissions_roles_admin_menu_restriction',20);
```
That's the easy part here.
Now I want before every admin page to load check if user has plugin permission to go to page (people still can go to page by url).
I made something that works but not everywhere. I explain under code.
```
function mr_permissions_roles_admin_page_restriction($screen)
{
global $menu;
$current_user=wp_get_current_user();
$role_restriction=get_option('mr_permissions_roles');
$role_restriction=(array)json_decode($role_restriction);
$role=$current_user->roles[0];
if(in_array($screen->base,$role_restriction[$role]))

I found that `current_screen` hook. Well hook which I wanted but not exactly. For example to post menu item slug is `menu-posts`. In `$screen` variable and $menu variable there no single thing I can compare. For custom admin menu pages it works well. $menu slug is in $screen->base so I can compare it. But when it comes to built-in pages it doesn't work. So here are a few questions which may solve my problem.
1. How to get admin menu item. Then I can save it in a different way and compare differently.
2. Is there any way I can get more data from `current_screen`.
3. Any other ideas?
4. (bonus) How can I get submenu pages for example for posts. `global $menu` doesn't have it. I would like to add to my plugin possibility to disable access to submenu pages (a few of them not all for example)
I even tried to look into database for any information but couldn't find anything.
I also made a custom page to edit every user to let them add posts to one or few of my custom\_posts. So for default Editor have no right to custom\_posts. When I want to make someone who will for example add companies (custom\_post) I go to users and I check checkbox and save. From now on this user with role editor can edit companies but others editors can't.

/YOUR\_THEME/page-templates/ will only work for custom page templates assigned on the admin page edit screen, not for page-$slug or page-$id named templates.
The correct filter hook in my view is page\_template, but you don't (I assume!) want to throw out any other possible templates for your pages, not least because you're bound to have some pages on your site for which you haven't made a /my-sub-dir/page-$slug.php template file.
The page\_template filter hook is called just after WP has found a template for the page using the standard template hierarchy. It would be handy if there was a filter to let you inject your additional template into the right part of the template hierarchy, but in the absence of that we'll need to replicate the search for page templates from WordPress's own get\_page\_template() function, found in /wp-includes/template.php:
```
function get_page_template() {
$id = get_queried_object_id();
$template = get_page_template_slug();
$pagename = get_query_var('pagename');
if ( ! $pagename && $id ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = get_queried_object();
if ( $post )
$pagename = $post->post_name;
}
$templates = array();
if ( $template && 0 === validate_file( $template ) )
$templates[] = $template;
if ( $pagename )
$templates[] = "page-$pagename.php";
if ( $id )
$templates[] = "page-$id.php";
$templates[] = 'page.php';
return get_query_template( 'page', $templates );
}
```
This function builds an array of possible templates for Pages. get\_query\_template() then uses locate\_template() to run through the array and return the filename of the first template found.
As we can't hook into the list of proposed templates, we'll sadly have to duplicate some of this work.
Here's our own function:
```
function tbdn_get_page_template() {
$id = get_queried_object_id();
$template = get_page_template_slug();
$pagename = get_query_var('pagename');
if ( ! $pagename && $id ) {
// If a static page is set as the front page, $pagename will not be set. Retrieve it from the queried object
$post = get_queried_object();
if ( $post )
$pagename = $post->post_name;
}
$templates = array();
if ( $template && 0 === validate_file( $template ) )
$templates[] = $template;
// if there's a custom template then still give that priority
if ( $pagename )
$templates[] = "our-sub-dir/page-$pagename.php";
// change the default search for the page-$slug template to use our directory
// you could also look in the theme root directory either before or after this
if ( $id )
$templates[] = "our-sub-dir/page-$id.php";
$templates[] = 'page.php';
/* Don't call get_query_template again!!!
// return get_query_template( 'page', $templates );
We also reproduce the key code of get_query_template() - we don't want to call it or we'll get stuck in a loop .
We can remove lines of code that we know won't apply for pages, leaving us with...
*/
$template = locate_template( $templates );
return $template;
}
add_filter( 'page_template', 'tbdn_get_page_template' );
```
Caveats:
1 - I haven't tested this, but if you're up to messing around with the template hierarchy then you should certainly be able to follow, test & adjust my code which is mostly copied from WP anyway.
2 - If future core code ever changes the template hierarchy for pages then the code above will go out-of-date.

<p>Right now, when I click on a menu item in the wordpress admin menu, the section that that page belongs to is automatically expanded.</p>
<p>For instance, if I click on a link in the Settings section then the whole Settings section is expanded:</p>
<p><a href="https://i.stack.imgur.com/jnYlU.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/jnYlU.png" alt="enter image description here"></a></p>
<p>If, on the other hand, I click on a link in the Appearance menu then the whole Appearance section is expanded:</p>
<p><a href="https://i.stack.imgur.com/SRfJM.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/SRfJM.png" alt="enter image description here"></a></p>
<p>Is there a function or action that disables that feature? That is to say, I do NOT want these sections to be expanded, but to remain closed like all of the other sections - i.e., like this:</p>

Right now, when I click on a menu item in the wordpress admin menu, the section that that page belongs to is automatically expanded.
For instance, if I click on a link in the Settings section then the whole Settings section is expanded:
[](https://i.stack.imgur.com/jnYlU.png)
If, on the other hand, I click on a link in the Appearance menu then the whole Appearance section is expanded:
[](https://i.stack.imgur.com/SRfJM.png)
Is there a function or action that disables that feature? That is to say, I do NOT want these sections to be expanded, but to remain closed like all of the other sections - i.e., like this:
[](https://i.stack.imgur.com/Iiyny.png)
|
I see two options here - override the CSS, or remove the "active" classes with JavaScript (sadly there is no action/filter that we can do this server-side) - I opted for the JS approach, it's cleaner, leaner and meaner:
```
function wpse_227037_remove_menu_classes() {
echo '<script>jQuery( ".wp-has-current-submenu.wp-menu-open" ).removeClass( "wp-has-current-submenu wp-menu-open" ).addClass( "wp-not-current-submenu" );</script>';
}
add_action( 'adminmenu', 'wpse_227037_remove_menu_classes' );
```
The `adminmenu` action fires *right* after the menu HTML, so the code will execute the moment all admin nodes are in the DOM.

<p>I have a fully functional Wordpress site and I want the to create a new separate website that displays the posts from the wordpress site using the Wordpress Rest API.
I understand that typing <a href="http://my-website/wp-json/wp/v2/posts" rel="nofollow">http://my-website/wp-json/wp/v2/posts</a> into a browser shows me this information but I want to code it into the new separate site. I don't even know where to start! Does anyone know how to help?</p>

<p>I am using Events Manager to control my Events, but Essential Grids to display previews of these events in various places throughout my site.

<p>Essentially I am trying to get Essential Grids to recognise the Date Field of the event and sort the grid accordingly. Whilst hiding events that are in the past.</p>

<p>To achieve what I have so far I did the following:</p>
<p>Added parameters field under source tab of Essential Grids:</p>
<pre><code>( 'meta_query' => array( array( 'meta_key' => '_event_start_date' , 'meta_value' => $today, 'compare' => '>=' , 'type' => 'date')) , 'orderby' => 'meta_value' , ) ); ?>
</code></pre>
<p>Added the following to my Functions PHP file:</p>
<pre><code>add_filter('essgrid_query_caching', 'eg_disable_caching', 10, 2);
function eg_disable_caching($do_cache, $grid_id){ //disable caching for the particular grid

add_filter('essgrid_get_posts', 'eg_modify_query', 10, 2);

I am using Events Manager to control my Events, but Essential Grids to display previews of these events in various places throughout my site. An example of this is <http://staging-dbmax.transitiongraphics.co.uk/events/>.
Essentially I am trying to get Essential Grids to recognise the Date Field of the event and sort the grid accordingly. Whilst hiding events that are in the past.
Thus far through research I have managed to isolate the grids and pull in the date, whilst hiding older events. However it doesn't quite work. Some of the events do not place correctly in the grid.
To achieve what I have so far I did the following:
Added parameters field under source tab of Essential Grids:
```
( 'meta_query' => array( array( 'meta_key' => '_event_start_date' , 'meta_value' => $today, 'compare' => '>=' , 'type' => 'date')) , 'orderby' => 'meta_value' , ) ); ?>
```
Added the following to my Functions PHP file:
```
add_filter('essgrid_query_caching', 'eg_disable_caching', 10, 2);
function eg_disable_caching($do_cache, $grid_id){ //disable caching for the particular grid
if($grid_id == 43 || $grid_id == 48 || $grid_id == 50){ //replace 1 with your desired grid id
return false;
}
return true;
}
add_filter('essgrid_get_posts', 'eg_modify_query', 10, 2);
function eg_modify_query($query, $grid_id){
if($grid_id == 43 || $grid_id == 48){ //replace 1 with your desired grid id
$query['meta_query'] = array( 'key' => '_start_ts', 'value' => current_time('timestamp'), 'compare' => '>=', 'type'=>'numeric' );
$query['meta_key'] = '_start_ts';
$query['meta_value'] = current_time('timestamp');
$query['meta_value_num'] = current_time('timestamp');
$query['meta_compare'] = '>=';
}
if($grid_id == 50){ //replace 1 with your desired grid id
$query['meta_query'] = array( 'key' => '_start_ts', 'value' => current_time('timestamp'), 'compare' => '<=', 'type'=>'numeric' );
$query['meta_key'] = '_start_ts';
$query['meta_value'] = current_time('timestamp');
$query['meta_value_num'] = current_time('timestamp');
$query['meta_compare'] = '<=';
}
return $query;
}
```
And finally, this HTML goes in the skin of the Grid to pull the date in from Events Manager:
```
[event post_id="%post_id%"]#_EVENTDATES[/event]
```
Obvously if anyone has a better solution, I'd be happy to use that instead, otherwise, there something in the above which is not sorting correctly?

After researching this quite a bit I managed to sort the Events Manager events by date in the [Essential Grid plugin](https://www.themepunch.com/portfolio/essential-grid-wordpress-plugin/).
If you started with the solution above, you can delete the added parameters field under source tab of Essential Grids, it's not needed anymore.
So here's what I have in `functions.php`. **Note**: I have grid 1 & 2 used for current events and sorted by ascending "event start date" and I suppose grid 99 would work for past events in descending order, but I did not test it.
```
/******************************************************************
* Querry for Essential Grid to work with events
******************************************************************/
add_filter('essgrid_query_caching', 'eg_disable_caching', 10, 2);
function eg_disable_caching($do_cache, $grid_id){ //disable caching for the particular grid
if($grid_id == 1 || $grid_id == 2 || $grid_id == 99){ //replace 99 with other grid id - see below
return false;
}
return true;
}
add_filter('essgrid_get_posts', 'eg_modify_query', 10, 2);
//This is for future events
function eg_modify_query($query, $grid_id){
if($grid_id == 1 || $grid_id == 2){ //replace with your grid id
$query['meta_query'] = array( 'key' => '_start_ts', 'value' => current_time('timestamp'), 'compare' => '>=', 'type'=>'numeric' );
$query['meta_key'] = '_start_ts';
$query['meta_value'] = current_time('timestamp');
$query['meta_value_num'] = current_time('timestamp');
$query['meta_compare'] = '>=';
$query['order'] = 'ASC';
$query['orderby'] = 'meta_value';
}
//This is for past events
if($grid_id == 99){ //replace 99 with your desired grid id
$query['meta_query'] = array( 'key' => '_start_ts', 'value' => current_time('timestamp'), 'compare' => '<=', 'type'=>'numeric' );
$query['meta_key'] = '_start_ts';
$query['meta_value'] = current_time('timestamp');
$query['meta_value_num'] = current_time('timestamp');
$query['meta_compare'] = '<=';
$query['order'] = 'DESC';
$query['orderby'] = 'meta_value';
}
return $query;
}
```
And this is the HTML that goes in my grid to get the content of the events:
```
[event post_id='%post_id%']
<span style="font-weight: bold;color: #597eba;">Date:</span> #_EVENTDATES<br>
<span style="font-weight: bold;color: #597eba;">Time:</span> #_EVENTTIMES<br>
<span style="font-weight: bold;color: #597eba;">Location:</span> #_LOCATIONTOWN (#_LOCATIONSTATE)
[/event]
```
You can use any Events Manager shortcodes for events or locations within the `[event]` tags.
I hope this can be useful for someone else.

After you have removed the comments bubble, you [add it again](https://codex.wordpress.org/Class_Reference/WP_Admin_Bar/add_node). The trick is that in the `$args` of `add_node` you have to set `parent` to `top-secondary`.
So it will look like this:
```
add_action( 'admin_bar_menu', 'wpse227079_toolbar_link_to_bubble', 999 );
function wpse227079_toolbar_link_to_bubble ( $wp_admin_bar ) {
$args = array(
'id' => 'wp-admin-bar-comments',
'parent'=> 'top-secondary',
'title' => 'QQ',
'href' => 'QQ',
'meta' => array( 'class' => 'QQ' )
);
$wp_admin_bar->add_node( $args );
}
```
Title needs the full html of the bubble, href the link where it is going and meta the class for the list item. You'll have to delve into the source code of the admin bar to find the right QQ's for the bubble.

<p>I am new to wordpress. I am running wordpress setup on <code>http://localhost/wordpress/</code>. I am facing two problems right now:</p>
<ul>
<li>Only the logged in users can access the site. So, I am trying to redirect the guest from home page to login page using the following code which is somehow isn't working:</li>

wp_redirect( wp_login_url() ); exit;

I am new to wordpress. I am running wordpress setup on `http://localhost/wordpress/`. I am facing two problems right now:
* Only the logged in users can access the site. So, I am trying to redirect the guest from home page to login page using the following code which is somehow isn't working:
>
> Path: `wp-content/themes/twentysixteen/header.php`
>
>
>
```
<?php
if(get_permalink() != wp_login_url() && !is_user_logged_in()){
wp_redirect( wp_login_url() ); exit;
}
?>
```
Since the above code wasn't working, I tried to move on by letting the user to login manually by clicking on the `login` button. Here is the working code:
```
<?php
if(get_permalink() != wp_login_url() && !is_user_logged_in()){
// wp_redirect( wp_login_url() ); exit;
?>
<a href="<?php echo wp_login_url( get_permalink() ); ?>" title="Login">Login</a>
<?php
}
?>
```
* From above code, when guest clicked on login he/she was redirecting to login page and When the user is logs in, the page is redirecting to wordpress admin i.e `wp-admin` instead of home page i.e `http://localhost/wordpress`.
### What I am trying to do is:
* Redirect the guest from home page to login page, if the user isn't logged in.
* And then redirect the user from login page to home page instead of wp-admin, when user logs in.

If I understood correctly, you need to check if the user is logged in, if not, redirect it to login page. If the user logs in succesfully, he should be redirected to the page he was trying to see. You can do this by using the `redirect` argument of [`wp_login_url()`](https://codex.wordpress.org/Function_Reference/wp_login_url).
This code should work (not tested):
```
add_action( 'init', 'cyb_restrict_guest_access' );
function cyb_restrict_guest_access() {
global $wp;
if( ! is_user_logged_in() && ! cyb_is_login_page() ) {
wp_redirect( wp_login_url( site_url( $wp->request ) ) );
exit;
}
}
function cyb_is_login_page() {
return in_array($GLOBALS['pagenow'], array('wp-login.php'));
}
```

<p>In my application user can publish a custom post from front end . And later admin or capable user can update or delete the post . What I want to do , is to determine if that post is seen by admin or capable user from a dashboard . A post meta "is_seen" is attached to my post , by default it is false . I want to make it true if admin or capable user open the post in edit mode . In short I want to do something when "Edit" link is clicked. </p>

I want to show the whole content of every page in feed .I search for it and found some plugin but I could not solve my problem.
I want when I enter `http://swissaudio.com/craftsmanship/feed` it provides me the page content in feed. How can I do that?
|
First set the post type to display on main feed page i.e. `/feed` using `pre_get_posts` hook
```
$q->set('post_type', array('post', 'page'));
```
On individual page WordPress shows comment feed then set it to `false` and display page content in feed.
```
$q->is_comment_feed = false;
```
In feed template WordPress calls `the_excerpt_rss()` which calls `get_the_excerpt()` so using `excerpt_length` filter change the length to max.
Complete Example:-
```
add_action('pre_get_posts', 'wpse_227136_feed_content');
/**
* Set post type in feed content and remove comment feed
* @param type $q WP Query
*/
function wpse_227136_feed_content($q) {
//Check if it main query and for feed
if ($q->is_main_query() && $q->is_feed()) {
//Set the post types which you want default is post
$q->set('post_type', array('post', 'page'));
}
//Check if it feed request and for single page
if ($q->is_main_query() && $q->is_feed() && $q->is_page()) {
//Set the comment feed to false
$q->is_comment_feed = false;
}
}
add_filter( 'excerpt_length', 'wpse_227136_excerpt_length', 999 );
/**
* Filter the except length to full content.
*
* @param int $length Excerpt length.
* @return int $length modified excerpt length.
*/
function wpse_227136_excerpt_length( $length ) {
if (is_feed() && !get_option('rss_use_excerpt')) {
return PHP_INT_MAX;
}
return $length;
}
```

<p>I have a custom post type called 'game' with some ACF fields. One of the fields is a Post Object(called review_link) that accepts posts from a category called 'reviews'. One other field is a taxonomy field(called gametags) looking for the post_tag taxonomy of the 'posts' </p>
<p>This is what I am trying to achieve:</p>
<ol>
<li><p>Whenever you are reading a post (post_type=post) within the category Reviews to be able to add information to the sidebar, from the Game (post_type=game) which has this specific post in the Post Object field.</p></li>
<li><p>Whenever you are reading a post (post_type=post) from any category, to be able to get that posts tags, and look in the Games (post_type=game) ACF fields, and specifically in the taxonomy field, to find any matching tags, and then show some Game info.</p></li>
</ol>
<p>My code for case 1 is the following and it works great:</p>
<pre><code>$reviewID = $post->ID;
if(in_category('reviews') ) {
$reviewArgs = array(
'post_type' => 'game',
'meta_query' => array(
array(
'key' => 'review_link',
'value' => ''.$reviewID.'',
'compare' => 'LIKE'
)
)
);
}
</code></pre>
<p>Now for case 2 I have tried the following:</p>
<pre><code>$tag_ids = wp_get_post_tags( $post->ID, array( 'fields' => 'ids' ) );
$reviewArgs = array(
'post_type' => 'game',
'meta_query' => array(
array(
'key' => 'gametags',
'value' => $tag_ids,
'compare' => 'IN'
)
)
);
</code></pre>
<p>The $tag_ids for an example post are: 818,436,435,43,46,77. If I replace the $tag_ids in the above code with 435 it matches. But if I try to add it like an array it doesn't. I have also tried serializing the array, looping the array etc. None of it works. I could make an array of meta queries but the thing is the number of tags in each post are random. I have also tried converting the array to a string and using'LIKE' instead of 'IN' and nothing.</p>
<p>Actually the above code throws a warning:
Warning: trim() expects parameter 1 to be string, array given in /.../public_html/wp-includes/class-wp-meta-query.php on line 594</p>
<p>I have tried almost everything to make case 2 work and could not. From what I realize the meta_query is not working as expected when the meta value is an array, although the Codex specifies that it can be an array. All the above code is placed in sidebar.php.</p>
<p>Any hints tips would be appriciated</p>
<p>Thanks in advance</p>

I have a custom post type called 'game' with some ACF fields. One of the fields is a Post Object(called review\_link) that accepts posts from a category called 'reviews'. One other field is a taxonomy field(called gametags) looking for the post\_tag taxonomy of the 'posts'
This is what I am trying to achieve:
1. Whenever you are reading a post (post\_type=post) within the category Reviews to be able to add information to the sidebar, from the Game (post\_type=game) which has this specific post in the Post Object field.
2. Whenever you are reading a post (post\_type=post) from any category, to be able to get that posts tags, and look in the Games (post\_type=game) ACF fields, and specifically in the taxonomy field, to find any matching tags, and then show some Game info.
My code for case 1 is the following and it works great:
```
$reviewID = $post->ID;
if(in_category('reviews') ) {
$reviewArgs = array(
'post_type' => 'game',
'meta_query' => array(
array(
'key' => 'review_link',
'value' => ''.$reviewID.'',
'compare' => 'LIKE'
)
)
);
}
```
Now for case 2 I have tried the following:
```
$tag_ids = wp_get_post_tags( $post->ID, array( 'fields' => 'ids' ) );
$reviewArgs = array(
'post_type' => 'game',
'meta_query' => array(
array(
'key' => 'gametags',
'value' => $tag_ids,
'compare' => 'IN'
)
)
);
```
The $tag\_ids for an example post are: 818,436,435,43,46,77. If I replace the $tag\_ids in the above code with 435 it matches. But if I try to add it like an array it doesn't. I have also tried serializing the array, looping the array etc. None of it works. I could make an array of meta queries but the thing is the number of tags in each post are random. I have also tried converting the array to a string and using'LIKE' instead of 'IN' and nothing.
Actually the above code throws a warning:
Warning: trim() expects parameter 1 to be string, array given in /.../public\_html/wp-includes/class-wp-meta-query.php on line 594
I have tried almost everything to make case 2 work and could not. From what I realize the meta\_query is not working as expected when the meta value is an array, although the Codex specifies that it can be an array. All the above code is placed in sidebar.php.
Any hints tips would be appriciated
Thanks in advance

I don't know if you can get one array to compare to the other directly, but you can create a loop to set up a `meta_query` array that will check for each of the IDs within the field separately:
```
$tag_ids = wp_get_post_tags( $post->ID, array( 'fields' => 'ids' ) );
$meta_query = array('relation' => 'OR');
foreach ($tags_ids as $tag_id) {
$meta_query[] = array(
'key' => 'gametags',
'value' => $tag_id,
'compare' => 'IN'
);
}
$reviewArgs = array(
'post_type' => 'game',
'meta_query' => $meta_query
);
```
Note: this could produce errors if no tags are set for the post so you might want to add some alternative handling for that case.
EDIT: try this to test for the exact matches later...
```
$review_query = new WP_Query( $reviewArgs );
while( $review_query->have_posts() ) {
$review_query->the_post();
global $post; $checkmatch = false;
$gametags = get_post_meta($post->ID,'gametags');
if (!is_array($gametags)) {$gametags = explode(',',$gametags);}
foreach ($tags_ids as $tag_id) {
if (in_array($tag_id,$gametags)) {$checkmatch = true;}
}
if ($checkmatch) {
// echo output
}
}
```

<p>My theme has a lot of templates. Most of them contain messages in the usual way:</p>

<p>This has several disadvantages. For instance, if I want to change the Read More message I have to browse all files to see if it is there. There's a larger risk of typos and it is more difficult to check for consistency in the messages. So, is there a way to concentrate messages in one place?</p>

Let's define the defaults:</p>\n\n<pre><code>$theme_messages_defaults = array (\n 'read-more' => __('Read more','tekko'),\n 'next-page' => __('Next page','tekko'),\n ... and so on ...\n )\n</code></pre>\n\n<p>Now, we have to transfer the defaults to the option.

Actually you have even more possibilities. You can add the messages to your option pages and have your clients change the texts without having to change templates. Hey, if you use mods in stead of options, you can even add them to the theme customizer. Beware that you would have to add an extra condition to <code>run_only_at_install_or_new_version</code> to prevent overriding client messages when the theme is updated.</p>\n\n<p><strong>Note:</strong> The above is adapted from a more complex setup I use myself, so there may be some typos.

This doesn't indicate localization problem. This indicates *templating* problem.
What if you want to change *markup* of Read More of whatever else? Do you have to do this in multiple places as well? Then it's more about how templates are structured and duplication in them.
Not that WordPress is particularly *good* at that, but still worth a consideration.

You make a typical mistake of *wondering* instead of *measuring*.
There are certainly performance implications to localization in WordPress. However *core* already does plenty of it to load localization for *itself*.
If your theme doesn't approach or exceed WP core in size of necessary translations then you are probably fine. If you want to be sure — profile performance and get sure. :) Wondering just wastes your time on hypotheticals that might not *need* to be addressed.

<p>I'm building a gallery page for a website and want to use the images from post types as background images with lightboxes. The code im using currently is this:</p>

You have it around the wrong way `has_custom_logo()` will return false if there is no logo.
`function_exists( 'the_custom_logo' )` however will return true if you are using a version of Wordpress that support this function.
So if you seperate your if statement like below it will work.
```
if( function_exists( 'the_custom_logo' ) ) {
if(has_custom_logo()) {
the_custom_logo();
} else {
echo "No logo";
}
}
```

<p>I have registered custom commands that scaffording some files. These commands don't rely on any wordpress funcionality, basically outputs some files with content (what commands do is irrelevant in this problem, so I won't paste here any code).</p>
<p>Example command: <code>wp make:some file</code></p>
<p>When I run these command <strong>when Wordpress is installed everything works perfectly</strong>, but <strong>if there is no Wordpress wp-cli alerts</strong> with:</p>
<pre><code>Error: This does not seem to be a WordPress install.
Pass --path=`path/to/wordpress` or run `wp core download`.
</code></pre>
<p>There is any way to run that commands without active Wordpress installation present?</p>

I have registered custom commands that scaffording some files. These commands don't rely on any wordpress funcionality, basically outputs some files with content (what commands do is irrelevant in this problem, so I won't paste here any code).
Example command: `wp make:some file`
When I run these command **when Wordpress is installed everything works perfectly**, but **if there is no Wordpress wp-cli alerts** with:
```
Error: This does not seem to be a WordPress install.
Pass --path=`path/to/wordpress` or run `wp core download`.
```
There is any way to run that commands without active Wordpress installation present?
|
You have it around the wrong way `has_custom_logo()` will return false if there is no logo.
`function_exists( 'the_custom_logo' )` however will return true if you are using a version of Wordpress that support this function.
So if you seperate your if statement like below it will work.
```
if( function_exists( 'the_custom_logo' ) ) {
if(has_custom_logo()) {
the_custom_logo();
} else {
echo "No logo";
}
}
```

But is `query_posts` really slower than some secondary query that happens in a template for instance with `get_posts`, or native that you call with

The fact is that if you're calling `query_posts()` from a theme then **it already is a secondary query**. WordPress has already queried the database once to get a certain page then it hits your `query_posts()` function and queries the database *again* creating a *second query* and overwriting the original request / data.
From a speed perspective you're not going to notice any difference. The `query_posts()` functions uses `WP_Query()` and takes microseconds to overwrite some global variables. The biggest overhead will come from you having to normalize your data and make up for any niche issues with pagination.
Simply put, it's all around inefficient. So, while there may not be a "big red button" that says "Don't press here!" it's pretty much implied that it shouldn't be pressed. It's not big and red but [The Codex specifically states](https://codex.wordpress.org/Function_Reference/query_posts):

If you want to be efficient and need to override the main query - use [`pre_get_posts`](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) which will modify the query parameters before it calls it from the database which saves an entire database call ( in that we don't need a secondary query ).

Is it a known problem with `WP_Query` that it doesn't display posts with large `meta_query` set?

<p>I use a <code><span></code> inside the loop and I would like to get each post format the post is containing as a class in separate <code>spans</code>.</p>
<p>Example: </p>
<p><strong>If</strong> the post format <strong>is video and private</strong>: I would like to render:</p>
<pre><code><span class="format-video"></span>
<span class="status-private"></span>
</code></pre>
<p>So far I have tried <code><span <?php get_post_format_string($class); ?>></span></code> which did not work for me because this will render all the post formats and status in one <code>span</code>, not in different <code>spans</code>...</p>

This is because all of these queries uses the <code>WP_Query</code> class to run build and run db queries to return the queried posts. <code>get_posts()</code> is a bit faster although it also uses <code>WP_Query</code>. The big difference is that <code>get_posts</code> passes <code>no_found_rows=true</code> to <code>WP_Query</code> which legally breaks pagination. </p>\n\n<p>What is true, the main query (<em>primary query</em>) runs on each and every page load according to the exact page being loaded. Removing the main loop and replacing it with a secondary query (<em>either <code>query_posts()</code>, <code>WP_Query</code> or <code>get_posts()</code></em>) is what is referred to as making the page slow.

I have done an extensive post on this which you can read <a href=\"https://wordpress.stackexchange.com/a/155976/31545\">here</a>. To alter the main query, always use <code>pre_get_posts</code> as it alters the query vars before the <code>WP_Query</code> class builds and runs the SQL query. There are also other filters (<em>post clause filters</em>) available in <code>WP_Query</code> which you can use to directly alter the SQL query</p>\n\n<p>What makes <code>query_posts</code> bad is that it alters the main query object on which many functions rely as <code>query_posts</code> does the following</p>\n\n<pre><code>$wp_query = new WP_Query()\n</code></pre>\n\n<p>and it also alters the conditional tags. For a full explanation, you can read my answer <a href=\"https://wordpress.stackexchange.com/a/191934/31545\">here</a>. A normal <code>WP_Query</code> does not do that</p>\n"

I use a `<span>` inside the loop and I would like to get each post format the post is containing as a class in separate `spans`.
Example:
**If** the post format **is video and private**: I would like to render:
```
<span class="format-video"></span>
<span class="status-private"></span>
```
So far I have tried `<span <?php get_post_format_string($class); ?>></span>` which did not work for me because this will render all the post formats and status in one `span`, not in different `spans`...

You ask:
>

>

>
The fact is that if you're calling `query_posts()` from a theme then **it already is a secondary query**. WordPress has already queried the database once to get a certain page then it hits your `query_posts()` function and queries the database *again* creating a *second query* and overwriting the original request / data.
From a speed perspective you're not going to notice any difference. The `query_posts()` functions uses `WP_Query()` and takes microseconds to overwrite some global variables. The biggest overhead will come from you having to normalize your data and make up for any niche issues with pagination.
Simply put, it's all around inefficient. So, while there may not be a "big red button" that says "Don't press here!" it's pretty much implied that it shouldn't be pressed. It's not big and red but [The Codex specifically states](https://codex.wordpress.org/Function_Reference/query_posts):
>
> **Note:** This function isn't meant to be used by plugins or themes.
>
>
>
If you want to be efficient and need to override the main query - use [`pre_get_posts`](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) which will modify the query parameters before it calls it from the database which saves an entire database call ( in that we don't need a secondary query ).

How to fix this?

1. Find file where is `register_sidebar` ( must be on theme folder or plugins )
2. add ID to sidebar
```
register_sidebar( array(
'name' => __( 'Main Sidebar', 'theme-slug' ),
'id' => 'change_me', // Add only this line
'description' => __( 'Widgets in this area will be shown on all posts and pages.', 'theme-slug' ),
'before_widget' => '<li id="%1$s" class="widget %2$s">',
'after_widget' => '</li>',
'before_title' => '<h2 class="widgettitle">',
'after_title' => '</h2>',
) );
```
Or you can just disable notification in `wp-config.php`
edit `WP_DEBUG` to false
```
define('WP_DEBUG', false);

<p>I feel there is a red button saying "Do not press" below <code>query_posts()</code>. For some time I am trying to demystify this phenomena with very low success to be honest. </p>
<p>For example, probable the main reason not to use this function is a broken pagination. Second, was it may be slow (read: calling twice), or there are better ways (<code>pre_get_posts</code>). There may be more reasons. </p>
<p>For those who may downwote this question from instinct, I would appeal, to hold at least for a week or so. There is always a second chance to do that. I am hardly waiting to see at least some answers, before a team pressure.</p>
<p>For those not read <a href="https://wordpress.stackexchange.com/questions/226960/why-query-posts-isnt-marked-as-deprecated">this</a> post, I would say that this function is nor deprecated, nor it is marked as <code>_doing_it_wrong</code>, nor there are plans.
Even the ticket to make it deprecated has been closed recently.</p>
<p>Some may say they read this function must not be used within the WordPress. I am providing in here the full function.</p>
<pre><code>File: /wp-includes/query.php
79: /**
80: * Set up The Loop with query parameters.
81: *
82: * This will override the current WordPress Loop and shouldn't be used more than
83: * once. This must not be used within the WordPress Loop.
84: *
85: * @since 1.5.0
86: *
87: * @global WP_Query $wp_query Global WP_Query instance.
88: *
89: * @param string $query
90: * @return array List of posts
91: */
92: function query_posts($query) {
93: $GLOBALS['wp_query'] = new WP_Query();
94: return $GLOBALS['wp_query']->query($query);
95: }
</code></pre>
<p>You can see <code>This must not be used within the WordPress Loop.</code>, meaning not within the WordPress loop, implying that before the WordPress loop may be not prohibited.</p>
<p>I noted <a href="https://wordpress.stackexchange.com/questions/227244/is-query-posts-really-slower-than-secondary-query">from this post</a> that this function is not slower than any secondary query (having the same arguments). </p>
<p>Bottomline, speaking of the pagination <code>query_posts</code> is much better solution for the pagination than the <code>get_posts</code> since <code>get_posts</code> actually disables <code>SQL_CALC_FOUND_ROWS</code>.</p>
<p>Some good thoughts on the <code>query_posts</code> may be:</p>
<ul>
<li>the query arguments are not limited, you can set anything you like.</li>
<li>you can even set the arguments to use pagination, if you don't plan to use core pagination functions; super easy you can create your own pagination</li>
<li>in a typical blog only small portion of the pages, may use pagination. The most of the pages, in a majority of regular simple cases, don't even use pagination so to do something quick and to reuse the main query templates (read loop) <code>query_posts</code> may be handy.</li>
</ul>
<p>These are just a the few thoughts, I am sure there are more, but certainly If you know what you are downing you cannot be wrong.</p>

Doing it this way will not result in any extra db queries being made, period. For true pages and static front pages, you can always use my <a href=\"https://wordpress.stackexchange.com/a/215027/31545\"><code>PreGetPostsForPages</code> class</a> or even <a href=\"https://stackoverflow.com/a/22142984/1908141\">the <code>pre_get_posts</code> method described by @birgire here</a>.</p>\n\n<p>You should never ever replace the main query with a custom one, neither using <code>query_posts</code>, a new instance of <code>WP_Query</code> or <code>get_posts</code>.

If you replace the main query with a custom one, you are running twice as many db calls which also increases page load times. Not just that, pagination becomes a nightmare. You should take your time and read <a href=\"https://wordpress.stackexchange.com/a/176412/31545\">this answer I have done on pagination</a>.</p>\n\n<p>You should only ever run custom queries for things like sliders, widgets, related posts and navigation menus, never ever to replace or alter the main query. </p>\n\n<p><code>query_posts</code> still stays a very problematic way to run custom queries as it alter the main query object stored in <code>$wp_query</code> (<em>$GLOBALS['wp_query']</em>) because so many functions and plugins relies on the main query object to run things like pagination and related posts and breadcrumbs</p>\n\n<p>As @toscho already mentioned, only use <code>query_posts</code> when there is no main query, which is for ajax calls, and some pages on the admin side. Apart from that, you really really should avoid using it, accepts when you really need to break something on the front end. </p>\n\n<p>As I said, there is absolutely no need at all to run any type of custom query in place of the main query just to alter or modify the output from the page. If you really need better performance and faster loading times, use <code>pre_get_posts</code> to alter the main query and never replace it for whatever reason at all. Custom queries are meant to do additional stuff like widgets, related posts and sliders</p>\n\n<h2>EDIT</h2>\n\n<p>As final note, and proof, download and install the Query Monitor plugin. This way you can see the drastic increase in page load time and db calls when you replace the main query with any custom query and how there is no difference when using <code>pre_get_posts</code></p>\n"

I feel there is a red button saying "Do not press" below `query_posts()`. For some time I am trying to demystify this phenomena with very low success to be honest.
For example, probable the main reason not to use this function is a broken pagination. Second, was it may be slow (read: calling twice), or there are better ways (`pre_get_posts`). There may be more reasons.
For those who may downwote this question from instinct, I would appeal, to hold at least for a week or so. There is always a second chance to do that. I am hardly waiting to see at least some answers, before a team pressure.
For those not read [this](https://wordpress.stackexchange.com/questions/226960/why-query-posts-isnt-marked-as-deprecated) post, I would say that this function is nor deprecated, nor it is marked as `_doing_it_wrong`, nor there are plans.
Even the ticket to make it deprecated has been closed recently.
Some may say they read this function must not be used within the WordPress. I am providing in here the full function.
```
File: /wp-includes/query.php
79: /**
80: * Set up The Loop with query parameters.
81: *
82: * This will override the current WordPress Loop and shouldn't be used more than
83: * once. This must not be used within the WordPress Loop.
84: *
85: * @since 1.5.0
86: *
87: * @global WP_Query $wp_query Global WP_Query instance.
88: *
89: * @param string $query
90: * @return array List of posts
91: */
92: function query_posts($query) {
93: $GLOBALS['wp_query'] = new WP_Query();
94: return $GLOBALS['wp_query']->query($query);
95: }
```
You can see `This must not be used within the WordPress Loop.`, meaning not within the WordPress loop, implying that before the WordPress loop may be not prohibited.
I noted [from this post](https://wordpress.stackexchange.com/questions/227244/is-query-posts-really-slower-than-secondary-query) that this function is not slower than any secondary query (having the same arguments).
Bottomline, speaking of the pagination `query_posts` is much better solution for the pagination than the `get_posts` since `get_posts` actually disables `SQL_CALC_FOUND_ROWS`.
Some good thoughts on the `query_posts` may be:
* the query arguments are not limited, you can set anything you like.
* you can even set the arguments to use pagination, if you don't plan to use core pagination functions; super easy you can create your own pagination
* in a typical blog only small portion of the pages, may use pagination. The most of the pages, in a majority of regular simple cases, don't even use pagination so to do something quick and to reuse the main query templates (read loop) `query_posts` may be handy.
These are just a the few thoughts, I am sure there are more, but certainly If you know what you are downing you cannot be wrong.

Opposite from the common believes `query_posts` is harmless if you know how to use it. I tried [here](https://wordpress.stackexchange.com/questions/226960/why-query-posts-isnt-marked-as-deprecated/248955#248955) to provide more arguments.
In here I will add a simple outline that you never should rely on:
`$GLOBALS['wp_query']`.
You should rely on `$GLOBALS['wp_the_query']` that should be frozen.
If you like to reset the `$GLOBALS['wp_query']` just use `wp_reset_query`.
### Use case
[](https://i.stack.imgur.com/vJvv9.png)
For example, if you need this on a homepage, after the main loop, you may call `query_posts` for the cpt1 and later `query_posts` again for the cpt2.

I am not sure I follow your question, title seems different from question itself.
You seem to want to get rid of `index.php` in URL?
It's hard to say confidently from outside, but it looks like [PATHINFO permalink](https://codex.wordpress.org/Using_Permalinks#PATHINFO:_.22Almost_Pretty.22).
If that's the case you would need to change your WP permalink configuration to more common "pretty" one. Doesn't have anything to do with CPT's config.

<p>So, I'm building a theme for a client with one page layout functionality. Currently, I'm allowing the user to create a parent page, and the modules within that page are separate pages that will be set as children of the main page. </p>
<p>Clarifying. I have a home page. Within the home page, I need to have a section to display a product tour and also a map. The client will create the parent page Home and then create a page called <code>Product Tour</code> & <code>Map</code>.

<p>Here's where I'm getting stuck. I need to allow my client to create a child page and set a custom page template that will then display on the main page.

I was able to figure this out and make it dynamic.
I created a variable `$template` that I put inside the loop, in which I stored the page template.
`$template = get_post_meta( $post->ID, '_wp_page_template', true );`
Then, I utilize this where I need the child pages to show up.
`<?php include(locate_template($template)); ?>`
This is working for me and is pulling each child page into the parent page according to their chosen page template. Here, for your enjoyment is the entirety of the code.
```
<?php
$this_page=get_query_var('page_id');
$loop = new WP_Query( array('post_type'=>'page', 'posts_per_page' => -1, 'post_parent' => $this_page, 'orderby' => 'menu_order', 'order' => 'ASC') );
while ( $loop->have_posts() ) : $loop->the_post();
<?php include(locate_template($template)); ?>
<?php endwhile; endif; ?>

<p>I'm wondering if it is at all possible to set display a page template chosen by the user within the context of a <code>query_posts</code> using <code>get_template_part</code>. In other words, I have set up a page template to pull all of it's child pages and display them, but I need each child page to display according to the page template that is chosen in the page editor. Is there any way to make that happen? Here is the code I have for the parent page template so far.</p>
<pre><code><?php
$this_page=get_query_var('page_id');
query_posts( array('post_type'=>'page', 'posts_per_page' => -1, 'post_parent' => $this_page, 'orderby' => 'menu_order', 'order' => 'ASC') );
if(have_posts()): while(have_posts()): the_post();
?>
<?php get_template_part('_wp_page_template'); ?>
<?php endwhile; endif; ?>
</code></pre>
<p>So, as you can see, I've got the query pulling all of the child pages. I'd like to know how I can make each of these child pages display according to their chosen page template.</p>
<p>Thanks.</p>

I'm wondering if it is at all possible to set display a page template chosen by the user within the context of a `query_posts` using `get_template_part`. In other words, I have set up a page template to pull all of it's child pages and display them, but I need each child page to display according to the page template that is chosen in the page editor. Is there any way to make that happen? Here is the code I have for the parent page template so far.
```
<?php
$this_page=get_query_var('page_id');
query_posts( array('post_type'=>'page', 'posts_per_page' => -1, 'post_parent' => $this_page, 'orderby' => 'menu_order', 'order' => 'ASC') );
if(have_posts()): while(have_posts()): the_post();
?>
<?php get_template_part('_wp_page_template'); ?>
<?php endwhile; endif; ?>
```
So, as you can see, I've got the query pulling all of the child pages. I'd like to know how I can make each of these child pages display according to their chosen page template.
Thanks.

I found one small and nice solution.
```
add_filter( 'nav_menu_link_attributes', 'cfw_add_data_atts_to_nav', 10, 4 );
function cfw_add_data_atts_to_nav( $atts, $item, $args )
{
$atts['data-hover'] = $item->title;
return $atts;
}
```
I tested it and it works.

`register_activation_hook()` only attaches a function to run on *activation* of your plugin, not on updating. See [the docs](https://codex.wordpress.org/Function_Reference/register_activation_hook) for full details, particularly this part:
>
> 3.1 : This hook is now fired only when the user activates the plugin and not when an automatic plugin update occurs (#14915).
>
>
>
Of course, you could force your hook to run by deactivating and re-activating your plugin, but you certainly don't want your users to have to do this :)
A better way would be to manage the 'database version' of your plugin - so perhaps, store the 'current version' number of your plugin in the database. When your plugin runs, check this version number against the real version of your plugin. If it is ever different... *that's* when you want to add this field to the database.
Of course, for brand new installs of v1.1 of your plugin, you still want to run this as you are currently. You just need to also consider the upgrade path that existing users - such as yourself in this instance - will take.

You simply need the [`is_sticky()`](https://developer.wordpress.org/reference/functions/is_sticky/) conditional check and then act on that. You would probably still need the `is_home()` and `!is_paged()` conditional check to only target stikies on the first page of the home page
```
if ( have_posts() ) :
while ( have_posts() ) :
the_post();
if ( is_sticky()
&& is_home()
&& !is_paged()
) {
// Do what you need to do for stickies
} elseif ( !is_sticky() ) {
// Do something else for non-stickies
}
endwhile;

Yes it does. Escaping depends on context and in worst case like using `esc_html` when writing directly to the DB are just a security hole.

If you already transformed A into B in the DB, it is a PITA to reconstruct for B what was the original A to apply the correct escape function on it.
Rule of thumb: In the DB you should store the raw values the user submitted (probably sanitized, but not escaped), escaping should be done only on output.

`$post` in the [callback function](http://v2.wp-api.org/extending/modifying/#examples) is an array, not an object. So you cannot use `$post->id`. Change it to `$post['id']` and it should work:
```
function slug_get_phone_number($post, $field_name, $request)
{
return get_post_meta($post['id'], '_phone', true);
}
```
I recommend to change `_phone` to `phone_number` or something else without underscore prefix. Because `_` is often used with private meta keys. Try to add a custom field which has meta key with `_` prefix directly to your post, you will see what I meant.

<p>I got stuck with some modifications and maybe someone could give me some help. </p>
<p><strong>What am I doing</strong></p>
<p>I use the multiple theme plugin to switch themes for my WordPress project. To switch between the themes a URL Parameter is added <strong><code>www.mydomain/?parameter=XYZ</code></strong>. So far everything works great. </p>
<p><strong>Where is the issue</strong></p>
<p>The problem is when I click on internal links within the page I am sent back to the basic theme as the links and URLS within the website do not have the URL parameter appended.</p>
<p>Please note that I am aware that the plugin has a sticky function that adds the parameter to most URLs but it does not work for all URLS and especially not those which are loaded with AJAX. Also I still need to be able to access the basic theme via the normal URL without parameters.</p>
<p><strong>What I am trying to do</strong></p>
<p>Within the <code>functions.php</code> of the specific theme I try to add a function that adds the needed parameter to all URLs that WordPress is generating.</p>
<p>Based on <a href="https://developer.wordpress.org/reference/functions/add_query_arg/" rel="nofollow noreferrer">this info</a>:<br>
I am in the position to at least echo the right URL</p>
<pre><code>//Add partner parameter
echo add_query_arg( 'partner', 'XYZ', get_permalink());
</code></pre>
<p>Unfortunately I have no clue how I may turn that into a function that all URLS within the loaded webpage get the parameter appended? Does anyone have an idea?</p>
<p><strong>What I already checked</strong></p>
<p><a href="https://wordpress.stackexchange.com/questions/188749/i-am-looking-to-append-url-parameter-to-all-urls">I am Looking to append URL Parameter to all URLs</a></p>
<p>As it is a redirection and not a rewrite of the URL I can't then access the normal URL without the parameter anymore.</p>

I got stuck with some modifications and maybe someone could give me some help.
**What am I doing**
I use the multiple theme plugin to switch themes for my WordPress project. To switch between the themes a URL Parameter is added **`www.mydomain/?parameter=XYZ`**. So far everything works great.
**Where is the issue**
The problem is when I click on internal links within the page I am sent back to the basic theme as the links and URLS within the website do not have the URL parameter appended.
Please note that I am aware that the plugin has a sticky function that adds the parameter to most URLs but it does not work for all URLS and especially not those which are loaded with AJAX. Also I still need to be able to access the basic theme via the normal URL without parameters.
**What I am trying to do**
Within the `functions.php` of the specific theme I try to add a function that adds the needed parameter to all URLs that WordPress is generating.
Based on [this info](https://developer.wordpress.org/reference/functions/add_query_arg/):
I am in the position to at least echo the right URL
```
//Add partner parameter
echo add_query_arg( 'partner', 'XYZ', get_permalink());
```
Unfortunately I have no clue how I may turn that into a function that all URLS within the loaded webpage get the parameter appended? Does anyone have an idea?
**What I already checked**
[I am Looking to append URL Parameter to all URLs](https://wordpress.stackexchange.com/questions/188749/i-am-looking-to-append-url-parameter-to-all-urls)
As it is a redirection and not a rewrite of the URL I can't then access the normal URL without the parameter anymore.

You can set the `$_GET` global internally. By saving the parameter passed as user meta and/or a cookie and retrieving it later. This would probably have to be put in your `/wp-content/mu-plugins/` folder to work properly (so it is loaded early):
```
<?php
$parameter = 'theme'; // default for theme test drive
$savemethod = 'both'; // 'usermeta' (only), 'cookie' (only) or 'both'
$expires = 7*24*60*60; // cookie length (a week in seconds)
if (!function_exists('is_user_logged_in')) {require(ABSPATH.WPINC.'/pluggable.php');}
if (is_user_logged_in()) {global $current_user; wp_get_current_user();}
if (isset($_GET[$parameter])) {
// sanitize querystring input (like a theme slug)
$originalvalue = $_GET[$parameter];
$value = sanitize_title($_GET[$originalvalue]);
if (!$value) {$value = '';}
// save parameter as usermeta
if ( ($savemethod != 'cookie') && (is_user_logged_in()) ) {
if ($value == '') {delete_user_meta($current_user->ID,$parameter);}
else {update_user_meta($current_user->ID,$parameter,$value);}
}
// save parameter value as cookie
if ($savemethod != 'usermeta') {
if ($value == '') {setCookie($parameter,'',-300);}
else {setCookie($parameter,$value,time()+$expires);}
}
}
elseif ( ($savemethod != 'cookie') && (is_user_logged_in()) ) {
// maybe set parameter from usermeta
$uservalue = get_user_meta($current_user->ID,$parameter,true);
if ($uservalue != '') {$_GET[$parameter] = $uservalue;}
}
elseif ($savemethod != 'usermeta') {
// maybe set parameter from cookie
if ( (isset($_COOKIE[$parameter])) && ($_COOKIE[$parameter] != '') ) {
$_GET[$parameter] = $_COOKIE[$parameter];
}
}
// parameter override debugging
if ( (isset($_GET[$parameter.'debug'])) && ($_GET[$parameter.'debug'] == '1') ) {
$debugfile = get_stylesheet_directory().'/'.$parameter.'-debug.txt';
$fh = fopen($debugfile,'a');
$debugline = $_SERVER['REQUEST_URI'].'::original:'.$originalvalue;
$debugline .= '::cookie:'.$_COOKIE[$parameter'].'::usermeta.'.$uservalue;
$debugline .= '::current:'.$_GET[$parameter].PHP_EOL;
fwrite ($debugfile,$debugline); fclose($fh);
}
?>
```
Usage: This could be used for making Theme Test Drive persistent on a per-user level, currently it only works on a user-role level and/or via non-persistent querystring. However, Theme Test Drive does not allow for site area selection - either the whole theme is switched for the user everywhere or nowhere.

<p>I am using the following code to show next/previous posts in my wordpress theme.</p>
<pre><code><?php
previous_post_link('<span class="left">&larr; %link</span>');
next_post_link('<span class="right">%link &rarr;</span>'); ?>
</code></pre>
<p>It's working but I want to limit the post title which is displayed in the link to a specific length because too big links don't work because of the space I have.
And I want to have the arrow within the link so that it shows link and arrow with the same style. Is that possible aswell?</p>
<p>Thank you!</p>

Here's a little coding that should implement this for you:
```
<?php $max_length = 5; // set max character length here
$next = get_next_post()->ID;
$prev = get_previous_post()->ID;
if( $prev ) {
$title = get_the_title( $prev );
$link = get_the_permalink( $prev );
$post_name = mb_strlen( $title ) > $max_length ? mb_substr( $title, 0, $max_length ) . ' ..' : $title;
?>
<span class="left">
<a href="<?php echo $link; ?>" rel="prev" title="<?php echo $title; ?>">← <?php echo $post_name; ?></a>
</span>
<?php
}
if( $next ) {
$title = get_the_title( $next );
$link = get_the_permalink( $next );
$post_name = mb_strlen( $title ) > $max_length ? mb_substr( $title, 0, $max_length ) . ' ..' : $title;
?>
<span class="right">
<a href="<?php echo $link; ?>" rel="next" title="<?php echo $title; ?>"><?php echo $post_name; ?> →</a>
</span>
<?php
} ?>
```
Hope that helps in your template.
Edit: small fix so this could work with multibyte characters. (mb\_strlen - mb\_substr)

<p>This one should be easy, but I can't figure it out.
I want to send an email that is HTML formatted, but also has an attachment. The attachment is being sent correctly, but the message is delivered as plaintext, like this: </p>
<pre><code><p>Hello!</p>
<p>&nbsp;</p>
<p>Some text.</p>
<p>&nbsp;</p>
<p>Best wishes,</p>
<p>Team</p>
</code></pre>
<p>If it was an email without attachment, I would force it to send html by changing the header as described <a href="https://developer.wordpress.org/reference/functions/wp_mail/" rel="nofollow">here</a>. But now I need the content type to be multipart / mixed (right?). So my question is: how do I convince <code>wp_mail()</code> to send my messages as html, and include the attachment? </p>

Reference link [click here](https://developer.wordpress.org/reference/functions/wp_mail/).
Using below code you can send the mail with html format.
```
$to = '[email protected]';
$subject = 'The subject';
$body = 'The email body content';
$headers = array('Content-Type: text/html; charset=UTF-8');
wp_mail( $to, $subject, $body, $headers );
// For attachment
$attachments = array( WP_CONTENT_DIR . '/uploads/file_to_attach.zip' );
$headers = 'From: My Name <[email protected]>' . "\r\n";
wp_mail( '[email protected]', 'subject', 'message', $headers, $attachments );

Post type names cannot contain capital letters. So behind the scenes, your CPT is probably called projectscpt rather than ProjectsCPT - hence it not matching the value in your array.

I have installed Visual Composer for a client and am now trying to remove the tab from the Dashboard menu. How can I do this?
[](https://i.stack.imgur.com/FN3by.jpg)
```
function remove_menus(){
remove_menu_page( ‘js_composer.php’ );
}
add_action( ‘admin_menu’, ‘remove_menus’ );
```
The code used above isn't working for me. It seems the path "js\_composer.php" is not correct.
|
It is not easy to find it out, but it is pretty easy if you know how.
Add this following code to your themes `functions.php`.
```
function custom_menu_page_removing() {
remove_menu_page('vc-welcome'); //vc
}
add_action( 'admin_init', 'custom_menu_page_removing' );
```
(Previously been `admin_menu`, now is `admin_init`)
This is how to find out for the next time:
If you want to hide a link from any plugin in the admin backend, simply use everything behind the `?page=` in this example case it's `vc-welcome`
No need for an additional plugin to remove/hide the link.

<p>I'm running a VPS with <code>Ubuntu 14.04.4 x64</code> and Apache <code>2.4.7</code>, and would like to set-up a WordPress site on it.

<p>I'm running a VPS with Ubuntu. I've installed the LAMP-stack, and would now like to make a couple of blogs/sites using WordPress. I'm thinking about creating new users for each blog and making a <code>public_html</code> directory for each user. This way each blog could be reached with <code>http://mysite/~some_blog</code>. </p>
<p>Space is however at a bit of a premium, so I was wondering if it's possible to install WordPress only once (eg. under <code>/var/www/html/</code> or perhaps <code>/var/www/wordpress</code>), and let all blogs access WordPress from there? </p>
<p>Of course they'd each also have a "private" directory in the <code>public_html</code> for each user, for individual configurations, uploads, and so on. Each blog/user would have their own MySQL database.</p>
<p>Are there better ways of doing this - one WP installation, multiple blogs - that I'm missing?</p>
<p>Also, is it possible to use only one shared MySQL-database for all blogs? (Not that I intend to do so, just curious...)</p>

<p>Been hitting my head against the wall on this for a while. If I have a add_rewrite_rules like so:</p>
<pre><code> $aNewRules = array('my-books/?$' => 'index.php?pagename=my-books');
</code></pre>
<p>This works correctly; going to <a href="http://example.com/my-books/" rel="nofollow">http://example.com/my-books/</a> shows <a href="http://example.com/index.php?pagename=my-books" rel="nofollow">http://example.com/index.php?pagename=my-books</a>.</p>
<p>However, this is case sensitive - going to "/My-bOoKs/" does not trip the rule (and thus shows the 404 page instead).</p>
<p>Is there an easy way to just mark it as case insensitive? I only make links with the lower case, sure, but users may add a capital on their own and I'd hate to lose the traffic to a 404 page.</p>
<p>Thanks!

As the answer below mentions, it is not possible to pass a flag to `add_rewrite_rule()`; however, it *is* possible to use an inline modifier. In your example, you would do this:
`$aNewRules = array('(?i)my-books/?$' => 'index.php?pagename=my-books');`
(note the `(?i)` in the regular expression).
The advantage of this approach is that your rewrite rules are much cleaner and more performant.
See [this page](https://www.regular-expressions.info/modifiers.html) on regular expression modifiers for more information.

I am creating an RSS feed. I have created a table in my database with 400 post id's. I have the rss feed coded I am now trying to link the two so my RSS feed runs only for the list of 400 posts from my table.
On my RSS feed page I can create an array by using a couple of id's (see below)
```
$myarray2 = array(12345,12346);
$args = array(
'post_type' => 'posttype',
'post__in' => $myarray2
);
```
This works and creates an RSS feed for id's 12345,12346.
I can also print the array of my 400 database table records on the page as follows;
```
$myarray = $wpdb->get_results("SELECT * FROM my_table");
print_r($myarray)
```
This produces data of this form
```
(
[0] => stdClass Object (
[id] => 145
)
[1] => stdClass Object (
[id] => 4573
)
[2] => continues.....
)
```
However I can not seem to get the code right to use `$myarray` with `post__in` for example
```
$myarray = $wpdb->get_results("SELECT * FROM my_table");
$args = array(
'post_type' => 'posttype',
'post__in' => $myarray

does not work. I have tried various variations but I am missing something about how to deliver a list of post id's from my array to `post__in`
What am I missing?

`post__in` accept array of post IDs e.g. `array(5, 4, 8, 9);`
Extending @bravokeyl comment. By default result is Object. As codex suggest you can change the output type of [`get_results()`](https://codex.wordpress.org/Class_Reference/wpdb#SELECT_Generic_Results) to these values.

Here we can change output to `ARRAY_A` then extract post IDs and pass to `post__in`
```
global $wpdb;
$fivesdrafts = $wpdb->get_results("SELECT ID FROM my_table", ARRAY_A);
$post_ids = array_map(function($single_array){

I realize that this question is being asked in a very generic fashion, without detailed specifics of the configuration in question, and thus I am not expecting answers that go beyond anything but *general* guidance.
With that, given a WordPress site that is:
* based on a typical "heavy" ("kitchen-sink included") theme, purchased via ThemeForest.net, and
* hosted on typical (entry-level, Linux-based) "cheap hosting," priced at under **$10**/month
... to what degree can one *realistically* expect that the use of properly-configured caching-plugins (such as W3 Total Cache) and a CDN solution (such as CloudFlare or MaxCDN) can significantly boost the sluggish performance of the current setup?
In other words, if we take as an upper limit the performance that might be achieved hosting that very same website on a "high-end" hosting package (say, WPEngine's "Professional" plan, at **$99**/month, or even their "Business" plan, at **$249**/month):
* Is there any realistic chance of achieving relatively-"zippy" performance *despite* the underlying "heavy" theme and relatively-weak infrastructure of the cheap hosting?
* Specifically, what ballpark percentage of "high-end" performance might realistically be achieved?
* And what estimated plugin- and CDN-related expenses would be required each month? Also: what ballpark percentage of peak performance might be achieved using only a "free" CDN plan?
Primarily, I'd like to receive -- if possible -- a "sanity check" that at least a "semi-respectable" level of performance can nevertheless be achieved with cheap hosting in my situation, with the proper tuning and external support (as well as *general* guidelines on the direction to take).

<p>I'm looking for some advice on how to make a gallery of images.
it is a particular bit a gallery, because I would show the last 5 post and a fixed post, for a total of 6 posts, in a specific order. ie the fixed post must be the third in the list.
The only method that I believe it is possible to create 3 loops, the first to see the last two post, the second to display the fixed post (by id), and the third to see other last three posts.
Something like this (most probably it is not correct):</p>
<pre><code> <?php $my_query = new WP_Query( 'posts_per_page=2' ); // get the latest 2 posts
while ( $my_query->have_posts() ) : $my_query->the_post();
$do_not_duplicate = $post->ID;
?>
<?php the_title(); ?>
<?php endwhile; ?>
<?php $my_query2 = new WP_Query( 'p=1' ); // get fixed post with id=1
while ( $my_query2->have_posts() ) : $my_query2->the_post();
?>
<?php the_title(); ?>
<?php endwhile; ?>
<?php $my_query3 = new WP_Query( 'posts_per_page=3' ); // get the latest 3 posts
while ( $my_query3->have_posts() ) : $my_query3>the_post();
if ( $post->ID == $do_not_duplicate ) continue; // don't show the same post of the first loop
?>
<?php the_title(); ?>
<?php endwhile; endif; ?>
</code></pre>
<p>There's a different way to do this without do many loops, considering that there's already one in the page ?</p>

I cannot think of a way of getting the latest 5 posts plus a specific one in a single query without using SQL.
If you don't mind using two queries, I think this would be an easy way to do what you intend:
```
//Get the latest 5 posts (which happens to be get_posts default 'posts_per_page' value)
$posts = get_posts();
//Build up an array with the IDs
$latests_posts_ids = wp_list_pluck( $posts, 'ID' );
//Insert the desired ID in the third position
$post_id_to_insert = 1;
$insert_position = 2; //which equals 3 when starting from 0
array_splice( $latests_posts_ids, $insert_position, 0, $post_id_to_insert );
//Get the posts based on the IDs and do not alter their order
$args = array(
'posts_per_page' => 6,
'post__in' => $latests_posts_ids,
'orderby' => 'post__in'
);
$posts = get_posts( $args );
//Parse the posts
foreach( $posts as $post ) :
setup_postdata( $post );
the_title();
endforeach;
```
I'm using [`get_posts()`](https://codex.wordpress.org/Template_Tags/get_posts) but you can safely use [WP\_query](https://codex.wordpress.org/Class_Reference/WP_Query) instead.
WordPress already handles possible duplicates in `post__in`, which would be the case if the post you want to insert is one of the latest 5.

<p>I'm digging out on old question as no solution came out.
<a href="https://wordpress.stackexchange.com/questions/190634/how-to-limit-page-pagination">How to limit page pagination</a></p>
<p>I'm looking for a way to limit pages on homepage and categories (archive.php).
I have around 200k posts spread into about 50 categories.
If I leave the default pagination, homepage has 20k pages.
Then most categories have over 5k pages.
This will send google in some long long loops... and each time a post is added (200/day) google will start again etc... when all I want is google to look into recent posts (this is a news website)</p>
<p>All I need is to let the visitors navigate threw the 10 first pages of each categories.</p>
<p>Is there a nice way for doing this?</p>
<p>I've tried different things described here without success.
<a href="https://wordpress.stackexchange.com/questions/194363/limit-number-of-pages-in-pagination">Limit number of pages in pagination</a></p>
<pre><code>// this didn't work (beyond page 10 "next page" take us back to page 1)
function wpcodex_filter_main_search_post_limits( $limit, $query ) {
return 'LIMIT 0, 100';
}
add_filter( 'post_limits', 'wpcodex_filter_main_search_post_limits', 10, 2 );
</code></pre>
<p>Removing the page links on page 10 would work for me even if you can manually enter page 11 and see page 11 posts... all I want is google not to find a link.</p>
<p>Deleting old posts is not an option, nor running a double query.</p>

I've tried different things described here without success.
[Limit number of pages in pagination](https://wordpress.stackexchange.com/questions/194363/limit-number-of-pages-in-pagination)
```
// this didn't work (beyond page 10 "next page" take us back to page 1)
function wpcodex_filter_main_search_post_limits( $limit, $query ) {
return 'LIMIT 0, 100';
}
add_filter( 'post_limits', 'wpcodex_filter_main_search_post_limits', 10, 2 );
```
Removing the page links on page 10 would work for me even if you can manually enter page 11 and see page 11 posts... all I want is google not to find a link.
Deleting old posts is not an option, nor running a double query.
Thanks for your help

I was lucky, the theme used it's own function, so it was easy to override.
Inspired by worpdress native get\_the\_posts\_navigation (wp-includes/link-template.php) here is what I end up using:
```
function my_get_the_posts_navigation( $args = array() ) {
$limit = 5;
$navigation = '';
// Don't print empty markup if there's only one page.
if ( $GLOBALS['wp_query']->max_num_pages > 1 ) {
$args = wp_parse_args( $args, array(
'prev_text' => __( 'Older posts' ),
'next_text' => __( 'Newer posts' ),
'screen_reader_text' => __( 'Posts navigation' ),
) );
$next_link = get_previous_posts_link( $args['next_text'] );
$p = (get_query_var('paged')) ? get_query_var('paged') : 1;
if ($p < $limit) {
$prev_link = get_next_posts_link( $args['prev_text'] );
} else {
$prev_link = false;
}
if ( $prev_link ) {
$navigation .= '<div class="nav-previous">' . $prev_link . '</div>';
}
if ( $next_link ) {
$navigation .= '<div class="nav-next">' . $next_link . '</div>';
}
$navigation = _navigation_markup( $navigation, 'posts-navigation', $args['screen_reader_text'] );
}
return $navigation;
}
function my_the_posts_navigation( $args = array() ) {
echo my_get_the_posts_navigation( $args );
}
// now override the theme pagination function
if ( ! function_exists( 'cactus_paging_nav' ) ) :
function cactus_paging_nav() {
my_the_posts_navigation();
}
endif;

<p>I am working on adding some functionality on a Wordpress plugin which after a certain click needs to call on some shortcode through ajax.</p>
<p>What I first attempted was to call the shortcode inside of the ajax processing in my functions.php file:</p>
<pre><code>add_action( 'wp_ajax_nopriv_showads', 'showads' );
function showads(){
echo do_shortcode('[myshortcode]');
wp_die();
}
</code></pre>
<p>Where I would move the output of the shortcode in the response of the ajax call. This shortcode did not execute at all.</p>
<p>So instead after some research in the "wp_localize_script" function inside of the plugin I would call the shortcode:</p>
<pre><code> wp_localize_script( 'script-handle', 'ajax_object',
array('ajaxurl' => admin_url( 'admin-ajax.php' ),
'adspace' => do_shortcode( '[myshortcode]' )
));
</code></pre>
<p>And in the response of the ajax I would move the output of the shortcode. </p>
<p>The problem I'm having at the moment is that as soon as the "wp_localize_script" function is called the output of the shortcode (it should create a google ad) is all stripped. </p>
<p>I'd like to know if there is a way to not have the shortcode output stripped or advice if I'm trying to solve this whole thing the incorrect way.</p>

Headers
-------
First off: The `http-equiv` meta tags are the HTML **equiv**alent of an HTTP response header. They **can not** override a header already sent by your web server. So their only use is as a fallback and they rarely provide any real help. In reality, you want to go in and fix the headers your server(s) is/are sending instead – or ask your host to do so if you are in a shared environment and are not allowed to do so.
Date and Time options
---------------------
All those can be retrieved via: `get_option( 'name' );`. The possible values are:
* Time format: `time_format` – default: `__('g:i a')` (string)
* Time zone: `timezone_string` – default: `null` (string)
* Date format: `date_format` – default: `__('F j, Y')` (string)
* GMT Offset: `gmt_offset` – default: `date('Z') / 3600` (integer)
Then there are several other possible functions that you can use, depending on what you are actually displaying (use "Conditional Tags" to switch):
* Single post or page (or custom post): [`the_date()`](https://codex.wordpress.org/Function_Reference/the_date)
* Archives: Use the most current post date for this archive…
* …
Here's your plugin, slightly reformatted to retrieve the timezone name from the GMT offset, account for [PHP Bug #44780](https://bugs.php.net/bug.php?id=44780) (props [uınbɐɥs](https://stackoverflow.com/a/11896631/376483)) and also custom settings from your admin UI. If that is not what you want, you will have to play a bit with the options. What is missing is the conditional switches
```
<?php
/* Plugin Name: "Last Modified" meta tag */
add_action( 'wp_head', function()
{
// Abort if not on at home/ on the front page as this is just an example
if ( ! ( is_home() or is_front_page() )
return;
$offset = get_option( 'gmt_offset' ) * 3600;
$zone = timezone_name_from_abbr( '', $offset, 1 );
! $zone and $zone = timezone_name_from_abbr( '', $offset, 0 );
$format = get_option( 'date_format' ).' '.get_option( 'time_format' ) );
// @TODO adjust to take post date or similar into account
$date = 'now';
printf( '<meta http-equiv="last-modified" content="%s" />',
( new DateTime( $date, $zone ) )
->format( $format )
);

I tried this and got no response:

You can save your time and server load by not using `wp_register_script` and `wp_register_style` when you don't need them definitely. `wp_enqueue_style` and `wp_enqueue_script` do the same job themselves when not involving excessive functions.
Here is easier and more readable code up to date with the accepted answer by @vancoder:
```
<?php
function opby_theme()
{
wp_enqueue_script(
'responsive-img',
get_template_directory_uri() .'/js/responsive-img.min.js',
array('jquery')
);
wp_enqueue_style(
'opby',
get_stylesheet_uri()
);
wp_enqueue_style(
'googleFonts',
'https://fonts.googleapis.co/css?family=Roboto+Slab:400,100|Bitter'
);
if ( is_post_type_archive('limitedrun') ) {
wp_enqueue_style(
'ltd-run-font',
'https://fonts.googleapis.com/css?family=Roboto:100,500'

}

<p><code>154.16.63.40 - - [22/May/2016:06:52:49 +0100] "POST /xmlrpc.php HTTP/1.1" 200 596 "-" "Googlebot/2.1 (+http://www.google.com/bot.html)"
</code> (Obviously this isn't a google bot because there is no reason for google to post to this file.)</p>
<p>I believe there are many solutions to this (<a href="https://www.digitalocean.com/community/tutorials/how-to-protect-wordpress-from-xml-rpc-attacks-on-ubuntu-14-04" rel="nofollow">This tutorial</a>) but I tend to lean towards just outright blocking access to the file. However I am unsure as to whether this site is actually using the service xmlrpc allows you to use. Is there any particular way I can check if the previous developer has put anything in place to use wordpress xmlrpc functionality?

<p>any help with this would be great!</p>

<p>If I allow from the ip address of the server would this work for plugins etc or do they all have their own IP address that would need to be added?</p>

You can save your time and server load by not using `wp_register_script` and `wp_register_style` when you don't need them definitely. `wp_enqueue_style` and `wp_enqueue_script` do the same job themselves when not involving excessive functions.
Here is easier and more readable code up to date with the accepted answer by @vancoder:
```
<?php
function opby_theme()
{
wp_enqueue_script(
'responsive-img',
get_template_directory_uri() .'/js/responsive-img.min.js',
array('jquery')
);
wp_enqueue_style(
'opby',
get_stylesheet_uri()
);
wp_enqueue_style(
'googleFonts',
'https://fonts.googleapis.co/css?family=Roboto+Slab:400,100|Bitter'
);
if ( is_post_type_archive('limitedrun') ) {
wp_enqueue_style(
'ltd-run-font',
'https://fonts.googleapis.com/css?family=Roboto:100,500'
);
}
}
add_action( 'wp_enqueue_scripts', 'opby_theme' );
```

It is very probably that when these actions are triggered without meta information, like your code does, the third party code deletes the meta fields.</p>\n"

Not sure about the problem with `wp_update_post` but it is a simple enough SQL query:
```
global $wpdb;
$query = "UPDATE ".$wpdb->prefix."posts SET post_status='draft' WHERE ID = '".$directory->ID."'";
$wpdb->query($query);
```

This must be fairly simple, but I'm puzzled. And I may be going about it backwards.
*How do I output a database option that is an array into a get\_posts array?*
I have an option in the database that stores some post IDs in the array format `1234,5678' . I can retrieve and echo them with
```
$options = get_option( 'pu_theme_options' );
$newspostids = $options['pu_textbox'];
echo $newspostids;
```
so I know am getting the output `1234,5678'. The database "option" is just text, saved from a form field in theme options.
What I need to do is get the data from that option into a `get_posts` array so I can display the posts by ID.
What I need is for `get_posts` to function like this:
```
$news = get_posts( array(
'post_type' => 'post',
'post__in'=> array(1234,5678)
) );
```
And, obviously, this doesn't work, putting the variable directly into the array and expecting it to output `1234,5678' :
```
$news = get_posts( array(
'post_type' => 'post',
'post__in'=> array($newspostids)
) );
```
So how should this work?
|
You could use [`wp_parse_id_list()`](https://developer.wordpress.org/reference/functions/wp_parse_id_list/) to sanitize your comma seperated list of post IDs. It's defined as:
```
function wp_parse_id_list( $list ) {
if ( !is_array($list) )
$list = preg_split('/[\s,]+/', $list);
return array_unique(array_map('absint', $list));
}
```
where we can see that it returns unique array values as well.
Note that [`absint()`](https://developer.wordpress.org/reference/functions/absint/) is defined in core as `abs( intval() )` and there's a difference in the max output of [`intval()`](http://php.net/manual/en/function.intval.php) for 32 and 64 bit systems according to the PHP docs.

`get_the_content` doesn't apply all of the filters that `the_content` runs before outputting the result. You can fix this by simply using:
```
<?php the_content(); ?>
```
in place of:
```
<?php echo $content; ?>
```
If you look at [the source for `the_content`](https://developer.wordpress.org/reference/functions/the_content/#source-code), you'll see the extra step it performs on what is returned from `get_the_content`.

There are many globals that are being set in a loop, not only `$post`, and you need to set all of them to get exactly the same behavior. To get this it is not enough to set `$post` but you also need to use [setup\_postdata](https://developer.wordpress.org/reference/functions/setup_postdata/)

I am currently working on an entertainment website and I am having issues with page load time. I would love to know if there is any method I can use to remove blank spaces from PHP, JS , CSS scripts running via the website.
As I believe this will reduce load time efficiently. Also please any pointers to how can I significantly reduce page load time. I am currently using Cloudflare CDN nameservers.
|
I write one php code what totaly filter all html elements but is integrated in main index.php on the root. That made rendering a little faster but you also can do CDN for all your images and media. That will speedup your page a mutch better. I normaly point `/wp-content/uploads/` to subdomain and my WP get all media from that subdomain what made WP 20 times faster.
**UPDATE**
I made one great regex what can work inside buffer. Copy/Paste this script in your theme `functions.php` and see magic.

For example, you may want to filter Text Widget content and allow shortcodes in it:</p>\n\n<pre><code>add_filter( 'widget_text', 'do_shortcode' );\n</code></pre>\n\n<p><code>do_shortcode()</code> can be also useful when you need the functionality of a shortcode, no matter the exact output you get or what callback it is used, you need the functionality.</p>\n\n<p>For example, a plugin/theme could redefine a shortcode, for example the gallery shortcode:</p>\n\n<pre><code>remove_shortcode( 'gallery', 'gallery_shortcode' );\nadd_shortcode( 'gallery', 'my_gallery_shortcode' );\n</code></pre>\n\n<p>In this case, if you need the gallery functionality, not the specific output of callback, using <code>do_shortcode( '[gallery]' )</code> within a theme could be justified. But no one should redeclare the gallery shortcode, instead <a href=\"https://developer.wordpress.org/reference/hooks/post_gallery/\" rel=\"nofollow\"><code>post_gallery</code> filter</a> should be used to modify the gallery shortcode output. So, the use of <code>do_shortcode('[gallery]')</code> would be a very edge use case.</p>\n\n<p>Same argument applies to any shortcode and the use of <code>do_shortcode()</code> is a very edge case in general.</p>\n"

Here's an example:
```
<?php echo do_shortcode('[course_complete]'); ?>
```
|
Is it Ok?
---------
Yes!
Is it Optimal?
--------------
No
What Would Be Better?
---------------------
Shortcodes map on to PHP functions, so why not cut out the middle man and go straight to the original function?
Are there any other downsides?
------------------------------
Yes!
That shortcode had to come from somewhere, now you have a dependency, maybe the plugin that has the shortcode gets deactivated, who knows
Are There Any Upsides?
----------------------
Yes! It's much easier to build a gallery shortcode programmatically then pass it into `do_shortcode` than it is to create one from scratch.
Even if you do bypass the shortcode and go straight to the original function, you still have the same problem mentioned above. If the shortcode doesn't exist, it'll degrade gracefully back to an empty string. You can use the shortcode inside post content too
So, best to use shotcodes ONLY in widgets + pages + posts?
----------------------------------------------------------
Is it **Ok**? Yes! But is it the **best**? Probably not
Shortcodes are awesome! But remember their purpose, if you need to put stuff in a template, you don't need to use a shortcode, but if needs must, that option's always there. The `do_shortcode` function is just a tool, and they're for embedding things in content, don't go using it as the foundations for your site or framework.

I have created a custom post type `portfolio_posts` using the CPT UI plugin. Using the same plugin, I have created a taxonomy `portfolio_category`. I have made multiple entries under this taxonomy.
I want to list all the entries under `portfolio_category`, but all I'm getting is an empty array.
Here's what I've tried:
```
$args = array(
'taxonomy' => 'portfolio_category'
);
$taxonomy = get_categories ($args);
echo '<pre>';
print_r($taxonomy);
exit;
```
When I replace `portfolio_category` with `category` I am successfully getting all the entries under `category`.
What am I missing here?
[Here is a screenshot of the entries under portfolio\_category](https://i.stack.imgur.com/HYFB5.png) and below is an example of how they are saved in the `wp_term_taxonomy` table.

<p>I have created a custom post type "brochures" which i am currently displaying with the code below (using ACF to display the brochure file).<br>
At the moment this displays all the brochures individually.<br></p>
<p>I have set up a custom taxonomy for this post type called "brochure_categories" so that i can categories the brochures into separate folders like the below.<br></p>
<p><strong>Brochure Category 1</strong><br>
Brochure 1<br>
Brochure 2<br>
<br>

Brochure 3<br>
Brochure 4<br>
<br>
<strong>Brochure Category 3</strong><br>
Brochure 5<br>
Brochure 6<br></p>

I have created a custom post type "brochures" which i am currently displaying with the code below (using ACF to display the brochure file).
At the moment this displays all the brochures individually.
I have set up a custom taxonomy for this post type called "brochure\_categories" so that i can categories the brochures into separate folders like the below.
**Brochure Category 1**
Brochure 1
Brochure 2
**Brochure Category 2**
Brochure 3
Brochure 4
**Brochure Category 3**
Brochure 5
Brochure 6
Rather displaying all the posts (like im doing with the code below), i want to display all of the brochure categories, and when a category is clicked it then displays the posts within that category.
How am i able to achieve this?
```
<ul class="brochures">
<?php
$temp = $wp_query;
$wp_query = null;
$wp_query = new WP_Query();
$wp_query->query('showposts=18&orderby=title&order=ASC&post_type=brochures'.'&paged='.$paged);
while ($wp_query->have_posts()) : $wp_query->the_post();
?>
<li><a target="_blank" href="<?php the_field('brochure_file'); ?>"><img src="<?php the_field('brochure_logo'); ?>"><h3><?php echo get_the_title(); ?></h3><h4>Click to view</h4></a>
</li>
<?php endwhile; ?>
<nav class="nextPrev">
<div class="prev"><?php previous_posts_link('« Previous') ?></div>
<div class="next"><?php next_posts_link('Next »') ?></div>
</nav>
<?php
$wp_query = null;
$wp_query = $temp; // Reset
?>
</ul>
```
|
Here is how i did it
```
$taxonomy = get_terms('portfolio_category', array( 'hide_empty' => 0 ));
```
i am able get all the items under portfolio\_category.

You need to specify a post type in your `WP_Query` arguments when you need to query any other post type accept the build in post type `post`.
By default, `post_type` is set to `post`, so when no specific post type is set manually by the user, `WP_Query` will query posts from the post type `post`
Additionally, `caller_get_posts` have been deprecated for a very very long time now. If you had debug turned on, you would have recieved a deprecation notice about this. The correct arguments to use is `ignore_sticky_posts`.
I would also not use the `$post` global as it is unreliable, for reliability, rather use `$GLOBALS['wp_the_query']->get_queried_object()`. You can read up on this subject in [my answer here](https://wordpress.stackexchange.com/a/220624/31545)
[`get_the_tags()`](https://developer.wordpress.org/reference/functions/get_the_tags/) is also faster than `wp_get_post_tags()` as the latter requires an extra db call.
One last note, `wp_reset_query()` is used with `query_posts`, the correct function to use with `WP_Query` is `wp_reset_postdata()`
In essence, you can try the following
```
$post_id = $GLOBALS['wp_the_query']->get_queried_object_id();
$tags = get_the_tags( $post_id );
if ( $tags
&& !is_wp_error( $tags )
) {
$args = [
'post__not_in' => [$post_id],
'post_type' => 'doing',
'tag__in' => [$tags[0]->term_id],
// Rest of your args
];
$my_query = new WP_Query( $args );
// Your loop
wp_reset_postdata();
}
```

<p>I'm trying to display a list of all my custom taxonomy terms with an image field that I have created in ACF. The ACF image field I have is <code><img src="<?php the_field('brochure_logo'); ?>"></code>, but how can I display that image in my code below? I have left a gap where the field needs to go, but I can't seem to output the image URL.</p>

I'm trying to display a list of all my custom taxonomy terms with an image field that I have created in ACF. The ACF image field I have is `<img src="<?php the_field('brochure_logo'); ?>">`, but how can I display that image in my code below? I have left a gap where the field needs to go, but I can't seem to output the image URL.
```
$taxonomy = 'brochure_categories';
$tax_terms = get_terms( $taxonomy );
?>
<ul class="downloadGrid">
<?php
foreach ( $tax_terms as $tax_term ) {
echo '<li>';
echo '<a href="' . esc_attr( get_term_link( $tax_term, $taxonomy ) ) .
'" title="' . sprintf( __( "View all posts in %s" ), $tax_term->name ) .
'" ' . '>';
echo '<img src=" " >';
echo $tax_term->name;
echo '</a>';
echo '</li>';
}
```
|
You can pass the term object as the second parameter to the\_field/get\_field.
```
echo '<img src="' . get_field( 'brochure_logo', $tax_term ) . '">';
```

<p>I want to display an archive page with pagination that lists all the categories on my site, and each link goes to that particular category archive page. So this would be like an archive page of category archives.</p>
<p>Each category on my site has a custom thumbnail created manually to match the category's permalink. I already have a layout setup to display all the categories but I'm doing this with a custom page template, so there's no pagination. This means all categories display on a single page which is a tad annoying(I have 100+ categories).</p>
<p>My current archive is setup with a specific custom page template name <code>page-catlist.php</code> but I'm willing to change this to any other type of template file.</p>
<p>Here's the current code I'm using to output all categories on one page:</p>
<pre><code>$args = array(
'orderby' => 'name',
'order' => 'ASC'
);
$cats = get_categories( $args );
$thm_pre = 'http://example.com/images/thumbs/';
$thm_end = '.png';
foreach($cats as $cat) {
$thumbnail = $thm_pre.$cat->slug.$thm_end;
// output the loop HTML here
// basically a list of category names & thumbs
// all linked to the cat URL by get_category_link()
}
</code></pre>
<p>I'm hoping there's a better way to do this so that I can add natural pagination, ideally with WP-PageNavi. Any help would be greatly appreciated!</p>

Paging a list of terms/categories/tags are quite easy, and to achieve that, you need minimal info.
Lets look at we need
* the amount of terms
* the amount of terms per page
* [`get_terms()`](https://developer.wordpress.org/reference/functions/get_terms/) (*Just note, the usage of `get_terms()` have changed in version 4.5*). You can also use `get_categories()` if you wish, `get_categories()` is just a wrapper function for `get_terms()`
So first we need to count the amount of terms. For this, we will use the `count` parameter in `get_terms()`
NOTE:
-----
* All code is untested and requires at least
+ PHP 5.4
+ WordPress 4.5
You can easily convert this to work with older versions of PHP and WordPress
```
$taxonomy = 'category';
$term_count = get_terms(
[
'taxonomy' => $taxonomy,
'fields' => 'count'
]
);
```
Now that we know the amount of terms, we can set the amount of terms we need per page, lets say 10
```
$terms_per_page = 10;
```
From the above, we can now work out how many pages we will have. The value here will be passed to the requires pagination function, in your case, to `wp_pagenavi()`
```
$max_num_pages = ceil( $term_count/$terms_per_page );
```
In this case, you would pass `$max_num_pages` to your pagination function
The next part would be to calculate our offset. We only want to retrieve the relevant amount of terms per page to keep things optimized. We do not need all 100+ terms per page. Querying only the needed 10 is much faster. So, we need to know on which page we are, are from that, we will calculate an offset. This will be passed to `get_terms()`, and will tell `get_terms()` how many terms to skip from the initial starting point.
Once have that, we must also tell `get_terms()` to only return 10 terms. Let look at the code for this piece
```
$current_page = get_query_var( 'paged', 1 ); // Change to 'page' for static front page
$offset = ( $terms_per_page * $current_page ) - $terms_per_page;
$terms = get_terms(
[
'taxonomy' => $taxonomy,
'order' => 'ASC',
'orderby' => 'name',
'number' => $terms_per_page,
'offset' => $offset
]
);
```
You will only have 10 terms per page according to pagination. You can now just loop normally through your terms
Just a note, you would want to make sure that you actually have terms returned from your `get_terms()` function.

<p>I have a homepage, work (as parent pages) and several pages (as child), but when it comes to articles, I can't choose the relation between them and the page Blog.</p>
<p>Resuming, I can choose the hierarchy relation between pages, but I'm in trouble putting the articles under a "directory" called blog.
If change the permalinks, I will change it for all pages and articles, so I'm lost on this.</p>
<p>Note: I have a blog page where there is a list of articles, but instead of www.claro.pt/blog/article - I have www.claro.pt/article</p>

Just a note, you would want to make sure that you actually have terms returned from your `get_terms()` function.

<p>I can't figure out how to filter the comment permalink on certain WP page that I use like this:</p>
<pre><code>if(condition is met) {
(filter the comment url)
}
</code></pre>
<p>...so that all the comment permalinks inside the page can be changed from this:</p>
<pre><code>http://example.com/slug-to-page/#comment-n
</code></pre>
<p>to this:</p>
<pre><code>http://example.com/new-slug/#comment-n
</code></pre>
<p>In short, I'm trying to change the url structure pointing out to the page permalink, excluding the <strong>site_url</strong> (front page url) and the <strong>comment slug</strong> (e.g. #comment-n)</p>
<p>So far, I've tried the example in the <a href="https://codex.wordpress.org/Plugin_API/Filter_Reference/comment_link" rel="nofollow">comment_link filter</a> and nothing happens here:</p>
<pre><code>function my_comment_link_filter( $link ) {
$link = str_replace( get_permalink() , $new_permalink_structure , $link );
return $link;
}
add_filter( 'comment_link', 'my_comment_link_filter', 10, 3 );
</code></pre>
<p>I'm doing it wrong, it seems, and would certainly appreciate any help.</p>

Paging a list of terms/categories/tags are quite easy, and to achieve that, you need minimal info.
Lets look at we need
* the amount of terms
* the amount of terms per page
* [`get_terms()`](https://developer.wordpress.org/reference/functions/get_terms/) (*Just note, the usage of `get_terms()` have changed in version 4.5*). You can also use `get_categories()` if you wish, `get_categories()` is just a wrapper function for `get_terms()`
So first we need to count the amount of terms. For this, we will use the `count` parameter in `get_terms()`
NOTE:
-----
* All code is untested and requires at least
+ PHP 5.4
+ WordPress 4.5
You can easily convert this to work with older versions of PHP and WordPress
```
$taxonomy = 'category';
$term_count = get_terms(
[
'taxonomy' => $taxonomy,
'fields' => 'count'
]
);
```
Now that we know the amount of terms, we can set the amount of terms we need per page, lets say 10
```
$terms_per_page = 10;
```
From the above, we can now work out how many pages we will have. The value here will be passed to the requires pagination function, in your case, to `wp_pagenavi()`
```
$max_num_pages = ceil( $term_count/$terms_per_page );
```
In this case, you would pass `$max_num_pages` to your pagination function
The next part would be to calculate our offset. We only want to retrieve the relevant amount of terms per page to keep things optimized. We do not need all 100+ terms per page. Querying only the needed 10 is much faster. So, we need to know on which page we are, are from that, we will calculate an offset. This will be passed to `get_terms()`, and will tell `get_terms()` how many terms to skip from the initial starting point.
Once have that, we must also tell `get_terms()` to only return 10 terms. Let look at the code for this piece
```
$current_page = get_query_var( 'paged', 1 ); // Change to 'page' for static front page
$offset = ( $terms_per_page * $current_page ) - $terms_per_page;
$terms = get_terms(
[
'taxonomy' => $taxonomy,
'order' => 'ASC',
'orderby' => 'name',
'number' => $terms_per_page,
'offset' => $offset
]
);
```
You will only have 10 terms per page according to pagination. You can now just loop normally through your terms
Just a note, you would want to make sure that you actually have terms returned from your `get_terms()` function.

<p>I'm currently working with a company to make a few basic tweeks to their WordPress site and I noticed that they have this on their sidebar:</p>

<p>I am looking particularly at the "Clients", "Offers", "Portfolio" and "Slider Offer" sections, I have never seen these before and believe that they have not been added with a plugin. It appears that they are post categories, as they have the same pin icon as the "Posts" section. Can anyone explain what these are, how they work and how to add them?</p>

WordPress Core post types are `post` and `page` that are visible in the admin menu. Other than these can be either a registered custom post type or a menu page.
A menu page can be added with the [`add_menu_page()`](https://developer.wordpress.org/reference/functions/add_menu_page/) function, and a similar thing can be done using [`register_post_type()`](https://codex.wordpress.org/Function_Reference/register_post_type), where a registered post type gets its own menu item where the following arguments are `true`:
```
<?php
$args = array(
'show_ui' => true,
'show_in_menu' => true
);
register_post_type( 'mycpt', $args );
```
Note that, `register_post_type()` is a plugin-territory function. But some themes include them into their `functions.php`. And in that case, it's also possible, a parent theme didn't include 'em, but a child theme did so into its `functions.php`. :)

<p>Can anyone tell me how to enable Bootstrap on a site using the twentyeleven theme?

By default, WordPress uses `$wp_object_cache` which is an instance of [`WP_Object_Cache`](https://developer.wordpress.org/reference/classes/wp_object_cache/) to save on trips to the database.
Trace back [`username_exists()`](https://developer.wordpress.org/reference/functions/username_exists/#source-code) function, you will notice that [`get_user_by()`](https://developer.wordpress.org/reference/functions/get_user_by/) uses [`WP_User::get_data_by()`](https://developer.wordpress.org/reference/classes/wp_user/get_data_by/#source-code) which return user data from `$wp_object_cache` immediately without checking if that user exists in database. Note that `$wp_object_cache` is stored in memory.
It means that if you deleted an user record directly in your database without cleaning up user cache, user data is still available. That's the problem.
So what you're missing?
1. Missing to [delete user the right way](https://developer.wordpress.org/reference/functions/wp_delete_user/#source-code).
2. Missing to [clean user cache](https://developer.wordpress.org/reference/functions/clean_user_cache/).

Consider the simplest `archive.php` possible:
```
<?php
get_header();
while ( have_posts() ) {
the_post();
the_title();
}
get_footer();
```
**What address should I type into the browser to get to this page and display all posts?** The permalink Custom Struction is set as "/%category%/%postname%/". I have tried going <http://example.com/posts> but that page returns simply a 404 error.

`archive.php` is very broad template, possibly used for many kinds of archives.
If you mean common reverse chronological view the link to that would be return of [`get_post_type_archive_link()`](https://developer.wordpress.org/reference/functions/get_post_type_archive_link/) for the specific post type.
Note that the native `post` post type is special case. For it archive is typically either site root or posts page, depending on site's configuration. Those *never* use `archive.php`, according to [template hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/).

<p>Is there any way to determine if a particular custom post type will be displayed on default archive pages or search results?</p>
<p>e.g.
Given a post type named (badly) <strong>books</strong>, is there a way to tell <strong>via code</strong> any of the following:</p>
<ul>
<li>If books show up on date archives</li>
<li>If books show up in search results</li>
<li>If books show up in author archives</li>
</ul>
<p>I know how to make custom post types show up in these, but I've been doing a bit of digging and can see no clean way to determine if a particular custom post type will show up in any of the above or not.</p>
<p>The main reason I'm looking for this is that I'm creating custom breadcrumb bars for a theme... and it would be nice to be able to show an authors breadcrumb bar if the custom post being viewed supports author functionality <strong>and</strong> shows up in the author archive.</p>

You can [get the post type object](https://developer.wordpress.org/reference/functions/get_post_type_object/) and check its properties. For example:
```
$post_type = get_post_type_object( 'books' );
if( $post_type->exclude_from_search ) {
// The post type is not included in search results
}
if( $post_type->has_archive ) {
// The post type has archive
}
```
As far I know, custom post types are not included in dates archives nor author archives if you don't code for it (using [`pre_get_posts`](https://codex.wordpress.org/Plugin_API/Action_Reference/pre_get_posts) for example). I mean, those options are not available while registering a post type. So, there is no way to check it from post type object.

Additionally to kaiser's answer, you can load customized .mo files that overrides the original file using [`load_textdomain_mofile` filter](https://developer.wordpress.org/reference/hooks/load_textdomain_mofile/). For example:
```
add_filter( 'load_textdomain_mofile', 'cyb_filter_load_textdomain_mofile', 10, 2 );
function cyb_filter_load_textdomain_mofile( $mofile, $domain ) {
if ( $domain == 'some-textdomain-to-override' ) {
$mofile = WP_LANG_DIR . '/overrides/' . basename( $mofile );
}
return $mofile;
}
```
It may be faster but you will be required to check for changes on every update in order to keep your .mo file syncrhonized with the original.

Can i add the `itemprop` to the `title` element and still use `wp_head()` and `add_theme_support( "title-tag" )`?
I want to create a theme and [get it approved on wordpres.org](https://themes.trac.wordpress.org/ticket/29732#comment:23) which uses microdata.
The preceding mean i want the HTML code looks as follows:
```

Since all `_wp_render_title_tag` does is check for `title-tag` theme support and wrap in `<title>` tags, there is really no reason why your existing implementation "shall not pass", since the proper implementation is already identical via:
```
<title itemprop="name"><?php echo wp_get_document_title(); ?></title>
```
when `_wp_render_title_tag` does:
```
echo '<title>' . wp_get_document_title() . '</title>' . "\n";
```
(since Theme Check is a guideline check, so what if it can't tell that a standard actually has been followed, that should in theory not stop it from passing?)
But in any case, you *can* get around this *and* improve the existing implementation at the same time by adding a customization override filter... by unhooking the existing action (as suggested by @birgire) and (my addition) hooking a wrapping function that calls `_wp_render_title_tag` and applies the filter to it:
```
if (has_action('wp_head','_wp_render_title_tag') == 1) {
remove_action('wp_head','_wp_render_title_tag',1);
add_action('wp_head','custom_wp_render_title_tag_filtered',1);
}
function custom_wp_render_title_tag_filtered() {
if (function_exists('_wp_render_title_tag')) {
ob_start();
_wp_render_title_tag();
$titletag = ob_get_contents();
ob_end_clean();
} else {$titletag = '';}
return apply_filters('wp_render_title_tag_filter',$titletag);
}
```
Since it's better practice to have a filter available anyway....... Then you can add your own use case customizations easily by using the new filter:
```
add_filter('wp_render_title_tag_filter','custom_wp_render_title_tag');
function custom_wp_render_title_tag($titletag) {
$titletag = str_replace('<title>','<title itemprop="name">',$titletag);
return $titletag;
}
```
Of course it would be much cleaner if the core function was simply updated to:
```
function _wp_render_title_tag() {
if ( ! current_theme_supports( 'title-tag' ) ) {
return;
}
echo apply_filters( 'wp_render_title_tag' , '<title>' . wp_get_document_title() . '</title>' . "\n" );
}
```

You can do this by hooking into the `edit-post.php` page. There are a variety of hooks you could use, for example, if you want to display a message below the edit title field, you could hook into `edit_form_after_title`.
See the example code I have below with comments:
```
add_action(
'edit_form_after_title', // the hook
'wpse_228208' // the function
);
function wpse_228208() {
global $post;
// confirm if the post_type is 'post'
if ($post->post_type!== 'post')
return;
// you can also perform a condition for post_status, for example, if you don't want to display the message if post is already published:
if ($post->post_status!== 'publish')
return;
// here goes your message
echo '<div style="">Hello world!</div>';
}
```

Answer from comments:
First, create a conditional to check if the user has already 'published' a post. If yes, simply redirect them.
One can use `update_post_meta` with the post ID without any problem. Simply use that information to populate the fields.

<p>I'm looking for a way to show a certain pinterest pinboard in a post. </p>
<p>I've found in the <a href="https://en.support.wordpress.com/embed-from-pinterest/" rel="nofollow">WordPress.com Documentation</a> that you can simply post your pinboards URL there. This is not possible on a selfhosted Wordpress installation so I guess that is something specific to wordpress.com.</p>
<p>What would be the easiest way to add a URL Handler that translates the pinterest URL into the needed embed code and include the pinterest js file?</p>

I found that <https://wordpress.org/plugins/pinterest-widgets> actually has the needed functionality but doesn't mention it in the description.
After installing and activating you can add a pinboard to a post by using the following shortcodes
```
[pin_board url="http://www.pinterest.com/pinterest/pin-pets/"]
[pin_board url="http://www.pinterest.com/pinterest/pin-pets/" size="header"]
[pin_board url="http://www.pinterest.com/pinterest/pin-pets/" size="custom" image_width="100" board_width="900" board_height="450"]
```
more options can be found on the plugins "settings" page after installing.

I am including a partial file both in `header.php` and in `footer.php` with `get_template_part('content-form');`
Is there an `if` clause I can use to check from where the file is being called? If it is called from within `footer.php`, then I would like to add a class name.
```
<div class="default-class <?php if (called_from_footer) echo 'footer-class'; ?>">
</div>
```
I could do this and style accordingly if there isn't a better solution, I am just curious:
```
<div class=footer-container">
<?php get_template_part('content-form') ;?>
</div>
```

This is not a *true* solution to your problem (checking which template loaded another), but it will work to test if the footer has been loaded or not, and thus if it's loading your partial:
```
if ( did_action( 'get_footer' ) ) echo 'footer-class';
```

<p>Using the google page speed test i saw that some images were too large and needed to be resized. I used the ftp to download the necessary images, resized them locally, and then used the media upload tool to import them into Wordpress. </p>
<p>I went to each relevant post and changed the feature image to use the new ones. In the media library the file name is the same as the updated images. However after updating and using the chrome inspect tool, I see that it is still using the old image size even though the visible appearance has changed.</p>
<p>The filenames are confusing me. The original images were named as follows: <code>image-1000x1000</code>. The new ones were named <code>image-500x500</code>. After updating the posts with the new images, chrome inspect is now showing: <code>image-500-1000x500-100</code>. What does this mean? Also, the original size of the photo is still the larger one. </p>
<p>Below is an image of the problem. Notice the size of the <strong>natural image</strong> it should be <code>450x450</code> now but it isn't.</p>

<p>Semi-new to WordPress, so apologies is this is an obvious question!</p>
<p>I'm trying to execute some JavaScript on a WordPress site, but only on the child pages of a specific parent page - so, I have example.com/books, and I want the script to run on example.com/books/foo, example.com/books/bar, example.com/books/wee, and so forth. I don't want it to run on example.com/books.</p>
<p>I know that I could just add in the script on each individual page, but I have other people editing the site who may add new book child pages, and they will not feel comfortable adding in Javascript.</p>
<p>Any solutions?</p>

Semi-new to WordPress, so apologies is this is an obvious question!
I'm trying to execute some JavaScript on a WordPress site, but only on the child pages of a specific parent page - so, I have example.com/books, and I want the script to run on example.com/books/foo, example.com/books/bar, example.com/books/wee, and so forth. I don't want it to run on example.com/books.
I know that I could just add in the script on each individual page, but I have other people editing the site who may add new book child pages, and they will not feel comfortable adding in Javascript.
Any solutions?

This is not a *true* solution to your problem (checking which template loaded another), but it will work to test if the footer has been loaded or not, and thus if it's loading your partial:
```
if ( did_action( 'get_footer' ) ) echo 'footer-class';
```

<p>I'm developing a WordPress theme using a template engine. I want my code to be as much compatible as possible with WP core functionality.</p>
<h2>Some context first</h2>
<p>My first problem was to find a way to <em>resolve</em> the template starting from a WP query. I solved that one using a library of mine, <a href="https://github.com/Brain-WP/Hierarchy">Brain\Hierarchy</a>.</p>
<p>Regarding <code>get_template_part()</code> and other functions that loads partials like <code>get_header()</code>, <code>get_footer()</code> and similar, it was pretty easy to write wrapper to template engine partial functionality. </p>
<h2>The issue</h2>
<p>My problem is now how to load comments template.</p>
<p>WordPress function <a href="https://developer.wordpress.org/reference/functions/comments_template/"><code>comments_template()</code></a> is a ~200 lines function that does a lot of things, which I want to do as well for maximum core compatibility.</p>
<p>However, as soon as I call <code>comments_template()</code>, a file is <code>require</code>d, it is the first of:</p>
<ul>
<li>the file in the constant <code>COMMENTS_TEMPLATE</code>, if defined</li>
<li><code>comments.php</code> in theme folder, if found</li>
<li><code>/theme-compat/comments.php</code> in WP includes folder as last resort fallback</li>
</ul>
<p>In short, there's no way to prevent the function to load a PHP file, which is not desirable for me, because I need to <em>render</em> my templates and not simply use <code>require</code>.</p>
<h2>Current solution</h2>
<p>At the moment, I'm shipping an empty <code>comments.php</code> file and I'm using <a href="https://developer.wordpress.org/reference/hooks/comments_template/"><code>'comments_template'</code></a> filter hook, to know which template WordPress wants to loads, and use feature from my template engine to load the template.</p>
<p>Something like this:</p>
<pre><code>function engineCommentsTemplate($myEngine) {
$toLoad = null; // this will hold the template path
$tmplGetter = function($tmpl) use(&$toLoad) {
$toLoad = $tmpl;
return $tmpl;
};
// late priority to allow filters attached here to do their job
add_filter('comments_template', $tmplGetter, PHP_INT_MAX);
// this will load an empty comments.php file I ship in my theme
comments_template();
remove_filter('comments_template', $tmplGetter, PHP_INT_MAX);
if (is_file($toLoad) && is_readable($toLoad)) {
return $myEngine->render($toLoad);
}
return '';
}
</code></pre>
<h2>The question</h2>
<p>This works, is core compatible, but... is there a way to make it work without having to ship an empty <code>comments.php</code>?</p>
<p>Because I don't like it.</p>

I'm developing a WordPress theme using a template engine. I want my code to be as much compatible as possible with WP core functionality.
Some context first
------------------
My first problem was to find a way to *resolve* the template starting from a WP query. I solved that one using a library of mine, [Brain\Hierarchy](https://github.com/Brain-WP/Hierarchy).
Regarding `get_template_part()` and other functions that loads partials like `get_header()`, `get_footer()` and similar, it was pretty easy to write wrapper to template engine partial functionality.
The issue
---------
My problem is now how to load comments template.
WordPress function [`comments_template()`](https://developer.wordpress.org/reference/functions/comments_template/) is a ~200 lines function that does a lot of things, which I want to do as well for maximum core compatibility.
However, as soon as I call `comments_template()`, a file is `require`d, it is the first of:
* the file in the constant `COMMENTS_TEMPLATE`, if defined
* `comments.php` in theme folder, if found
* `/theme-compat/comments.php` in WP includes folder as last resort fallback
In short, there's no way to prevent the function to load a PHP file, which is not desirable for me, because I need to *render* my templates and not simply use `require`.
Current solution
----------------
At the moment, I'm shipping an empty `comments.php` file and I'm using [`'comments_template'`](https://developer.wordpress.org/reference/hooks/comments_template/) filter hook, to know which template WordPress wants to loads, and use feature from my template engine to load the template.
Something like this:
```
function engineCommentsTemplate($myEngine) {
$toLoad = null; // this will hold the template path
$tmplGetter = function($tmpl) use(&$toLoad) {
$toLoad = $tmpl;
return $tmpl;
};
// late priority to allow filters attached here to do their job
add_filter('comments_template', $tmplGetter, PHP_INT_MAX);
// this will load an empty comments.php file I ship in my theme
comments_template();
remove_filter('comments_template', $tmplGetter, PHP_INT_MAX);
if (is_file($toLoad) && is_readable($toLoad)) {
return $myEngine->render($toLoad);
}
return '';
}
```
The question
------------
This works, is core compatible, but... is there a way to make it work without having to ship an empty `comments.php`?
Because I don't like it.

Not sure the following solution is *better* than the solution in OP, let's just say is an alternative, probably more hackish, solution.
I think you can use a PHP exception to stop WordPress execution when `'comments_template'` filter is applied.
You can use a custom exception class as a DTO to *carry* the template.
This is a draft for the excepion:
```
class CommentsTemplateException extends \Exception {
protected $template;
public static function forTemplate($template) {
$instance = new static();
$instance->template = $template;
return $instance;
}
public function template() {
return $this->template;
}
}
```
With this exception class available, your function becomes:
```
function engineCommentsTemplate($myEngine) {
$filter = function($template) {
throw CommentsTemplateException::forTemplate($template);
};
try {
add_filter('comments_template', $filter, PHP_INT_MAX);
// this will throw the excption that makes `catch` block run
comments_template();
} catch(CommentsTemplateException $e) {
return $myEngine->render($e->template());
} finally {
remove_filter('comments_template', $filter, PHP_INT_MAX);
}
}
```
The `finally` block requires PHP 5.5+.
Works the same way, and doesn't require an empty template.

<p>Playing with WordPress customization I created a meta box with several others that report back details of the post. One meta box evaluates the featured image but I am having trouble figuring out how to fire the AJAX in the content of the meta box. At first I thought I would need to look into <code>admin-ajax.php</code> so I followed <a href="https://premium.wpmudev.org/blog/using-ajax-with-wordpress" rel="nofollow noreferrer">Using AJAX With PHP on Your WordPress Site Without a Plugin</a> but after looking into it I need to check if the post has a thumbnail loaded in the meta box content. I searched under the tag <a href="/questions/tagged/media" class="post-tag" title="show questions tagged 'media'" rel="tag">media</a> and tag <a href="/questions/tagged/javascript" class="post-tag" title="show questions tagged 'javascript'" rel="tag">javascript</a> and what I found was <a href="https://wordpress.stackexchange.com/questions/202988/trigger-js-when-featured-image-upload-window-is-opened-in-admin">Trigger JS when featured image upload window is opened in admin</a> which led me to search for <code>wp.media.featuredImage</code> but how can I build my function with AJAX to run when the featured image is loaded but if it isn't then do not.</p>
<p>I can get it to work by using:</p>
<pre><code>function foobar_metabox_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'metabox_meta_nonce' );
$metabox_stored_meta = get_post_meta( $post->ID );
if ( has_post_thumbnail() ) { ?>
<p>
<!-- show results -->
</p>
<?php } else { ?>
<p>No Featured Image not loaded</p>
<?php
}
// test the meta content
$getPostCustom=get_post_custom();
var_dump($getPostCustom);
}
</code></pre>
<p>but that is only if I refresh after the featured image has been loaded to the post. How can I get the function <code>foobar_metabox_callback()</code> to run without refreshing using <code>admin-ajax.php</code> if possible?</p>

Playing with WordPress customization I created a meta box with several others that report back details of the post. One meta box evaluates the featured image but I am having trouble figuring out how to fire the AJAX in the content of the meta box. At first I thought I would need to look into `admin-ajax.php` so I followed [Using AJAX With PHP on Your WordPress Site Without a Plugin](https://premium.wpmudev.org/blog/using-ajax-with-wordpress) but after looking into it I need to check if the post has a thumbnail loaded in the meta box content. I searched under the tag [media](/questions/tagged/media "show questions tagged 'media'") and tag [javascript](/questions/tagged/javascript "show questions tagged 'javascript'") and what I found was [Trigger JS when featured image upload window is opened in admin](https://wordpress.stackexchange.com/questions/202988/trigger-js-when-featured-image-upload-window-is-opened-in-admin) which led me to search for `wp.media.featuredImage` but how can I build my function with AJAX to run when the featured image is loaded but if it isn't then do not.
I can get it to work by using:
```
function foobar_metabox_callback( $post ) {
wp_nonce_field( basename( __FILE__ ), 'metabox_meta_nonce' );
$metabox_stored_meta = get_post_meta( $post->ID );
if ( has_post_thumbnail() ) { ?>
<p>
<!-- show results -->
</p>
<?php } else { ?>
<p>No Featured Image not loaded</p>
<?php
}
// test the meta content
$getPostCustom=get_post_custom();
var_dump($getPostCustom);
}
```
but that is only if I refresh after the featured image has been loaded to the post. How can I get the function `foobar_metabox_callback()` to run without refreshing using `admin-ajax.php` if possible?

I couldn't find any WP specific event to hook in to. What you can do is set up an observer with a callback to respond to DOM changes using `MutationObserver` and check if the your featured image has been added in the callback.
There's [no support](http://caniuse.com/#feat=mutationobserver) in IE < 11 though, which may be a deal breaker for you, or maybe not.
I've done minimal testing on this, but it works for me:
```
MutationObserver = window.MutationObserver || window.WebKitMutationObserver;
var observer = new MutationObserver(function(mutations, observer) {
// Fires every time a mutation occurs...
// forEach all mutations
mutations.forEach(function(mutation) {
// Loop through added nodes
for (var i = 0; i < mutation.addedNodes.length; ++i) {
// any images added?
if ( mutation.addedNodes[i].getElementsByTagName('img').length > 0) {
alert('Featured Image Added');
// Your featured image now exists
console.log( $('#postimagediv img') );
// Do some AJAX...
}
}
});
});
// define what element should be observed (#postimagediv is the container for the featured image)
// and what types of mutations trigger the callback
var $element = $('#postimagediv');
var config = { subtree: true, childList: true, characterData: true };
observer.observe( $element[0], config );
```
There's probably a better way to check for the featured image than just checking for an `img` element. You may want to have a var to keep track of the featured image so you can easily check for it being removed too (or just check `removedNodes` in the observer callback).
This won't run on page load so you should check if a featured image exists there first.

<p>So...here is part of my code for a plugin. I'm a newb of sorts so be kind. I've read up on global variables but I can't seem to get it to work and I've read you shouldn't use them anyway. So what would be the best way to write the code below without having to re-declare the variables for each function? Here is the <a href="http://pastebin.com/8c5BAZPc" rel="nofollow">full code</a> if necessary.</p>

<p>I am working on a site for a client who has a theme built for them by a different developer. They have asked me to make some changes to the site, and I'd like to put all of my changes into a plugin as a courtesy to the original theme developer. So far this is simple with functions and CSS. Now I need to change a theme file. Essentially I'd like to replace one theme file with a different one that I've edited heavily. </p>
<p>In the theme, the file I'd like to replace is called with this:</p>
<pre><code>get_template_part( 'partials/post', 'sidebar' );
</code></pre>
<p>What I'd like to do is to somehow write a function in my plugin that catches the above statement and redirects that template request to a file that resides in my plugin directory. </p>
<p>I have absolutely no idea how to do this, and searching has so far turned up very little help. Is this possible?</p>

**TL;DR:** Use a **[child theme](https://codex.wordpress.org/Child_Themes)** instead :)
---
If we dig into the [code for get\_template\_part()](https://developer.wordpress.org/reference/functions/get_template_part/), there's an action there - `get_template_part_{$slug}` - which we could hook into.
Digging a bit further, get\_template\_part() calls [locate\_template()](https://developer.wordpress.org/reference/functions/locate_template/), which calls [load\_template()](https://developer.wordpress.org/reference/functions/load_template/). Unfortunately, there's nothing in either of these functions that seems to be pluggable, so we can't hook in and change anything (with the exception of being able to set variables through the call to extract() in load\_template().... but we can't override the template file being called so it's not very useful anyway!)
So, it looks like your only option to catch this is by running code on the `get_template_part_partials/post` action. The problem is, this won't allow you to filter the template called - it'll just allow you to run some code *when* the template is called. If all you want to do is add some output *above* the templated code then this will suit you perfectly, but I doubt that's all you want to do!
The way around all this is to **use a child theme**.
You said you wanted to put your code into a plugin in order to respect the original theme developer. Firstly, that respect is awesome - many developers wouldn't care less so I commend you for that!
However, is a plugin the best choice? Plugins are generally used to add modular functionality to a site, not to change the look and feel of it. That's the domain of themes.
You can in fact [create a child theme](https://codex.wordpress.org/Child_Themes) which will let you modify the theme the site uses *without* making any changes to the parent theme. You should be able to apply all the changes you've already made here, plus you have the bonus that *get\_template\_part() will automatically use a file within your child theme if it exists*, before falling back to the parent theme.

<p>I am searching online and all I can see is how to <em>increase</em> file size for media upload, which I know how to do with <code>php.ini</code>, but what I need to do is limit the file size for media upload only.</p>
<p>The client and his associates have trouble with understanding: Please do not upload images that are bigger than 1MB because your site will load forever.</p>
<p>They keep uploading images that are over 8 MB in size, and the whole site takes over 30 sec to load. It's horrendous.</p>
<p>So I was thinking - if it's possible to limit the image upload to 1 MB or so without affecting the general <code>upload_max_filesize</code> which will influence the ability to upload themes and plugins (and I don't want that to happen).</p>
<p>Any idea if this can be done?</p>

I am searching online and all I can see is how to *increase* file size for media upload, which I know how to do with `php.ini`, but what I need to do is limit the file size for media upload only.
The client and his associates have trouble with understanding: Please do not upload images that are bigger than 1MB because your site will load forever.
They keep uploading images that are over 8 MB in size, and the whole site takes over 30 sec to load. It's horrendous.
So I was thinking - if it's possible to limit the image upload to 1 MB or so without affecting the general `upload_max_filesize` which will influence the ability to upload themes and plugins (and I don't want that to happen).
Any idea if this can be done?

Yes, you can use the `wp_handle_upload_prefilter` that allows you to stop the uploading process if a specific condition is not accomplished.
In your case, you could try this code snippet:
```
function limit_upload_size( $file ) {
// Set the desired file size limit
$file_size_limit = 1024; // 1MB in KB
// exclude admins
if ( ! current_user_can( 'manage_options' ) ) {
$current_size = $file['size'];
$current_size = $current_size / 1024; //get size in KB
if ( $current_size > $file_size_limit ) {
$file['error'] = sprintf( __( 'ERROR: File size limit is %d KB.' ), $file_size_limit );
}
}
return $file;
}
add_filter ( 'wp_handle_upload_prefilter', 'limit_upload_size', 10, 1 );
```
Hope it helps!

<p>I am facing a problem to set default value for the checkbox field in WordPress.
I have a checkbox input field (metabox) in a custom post. I want the checkbox to be checked by default. and if user uncheck it then it should be saved and unchecked and remain unchecked when page is refreshed. My problem is that I can not set the default value for the checkbox. I have only two values to work with. Main problem arises, because the savemetadata function runs when I click 'add new' post, So, a default value gets saved in the database automatically without saving the new post. I have been trying for 3 days now. I have tried to save a default value 'yes' when user does not check the checkbox. </p>
<p>but in that case, when user does uncheck then still it become checked with the default value.
my current code snippet </p>
<pre><code>// for displaying metabox
function aps_add_meta_box() {
add_meta_box(
'aps_metabox',
__( 'Slider Settings & Shortcode Generator', APS_TEXTDOMAIN ),
'aps_metabox_cb', // callback
'apspostslider', // screen or posttype
'normal'
);}
add_action( 'add_meta_boxes', 'aps_add_meta_box' );
function aps_metabox_cb( $post ) {

<input type="checkbox" name="aps_display_post_title" value="yes" <?php checked( $aps_display_post_title, 'yes'); />
}

<p>The code for saving metabox data in the save fucntion:</p>

I think the problem might could be the logic with using `checked`...
```
<input type="checkbox" name="aps_display_post_title" value="yes" <?php if ($aps_display_post_title != 'no') {echo 'checked';} ?> />
```
...on the other hand then running `sanitize_text_field` on the checkbox value might also be causing the problem.
Instead you might want to break the logic down differently so it is easier to understand, and use this with the code above which checked that the value is not `no` and so will default as checked:
```
if ( (isset($_POST['aps_display_post_title']))
&& ($_POST['aps_display_post_title'] == 'yes') ) {
$aps_display_post_title = 'yes';}
} else {$aps_display_post_title = 'no';}
update_post_meta($post_id, "aps_display_post_title", $aps_display_post_title);
```
**UPDATE**
To prevent the metasave function from firing on post creation, hook to `edit_post` instead of `save_post` (and do the post type check internally using the second argument passed which is `$post`)...
```
add_action( 'edit_post', 'aps_meta_save', 10, 2);
function aps_meta_save($post_id, $post) {
if ($post->post_type != 'apspostslider') {return;}
...
```

I don't see anywhere in your code that the query is being modified. Just flagging a column to be sortable doesn't mean it knows how to sort the data - it will just add the little up/down arrow and make the column clickable but you have to intercept the query var accordingly and tell WP what to do. You'll want to hook into `pre_get_users` and modify the query accordingly. Since you're already storing the time using `current_time( 'mysql' )` then the default ordering should work as intended.
This is untested but should work or at least get you started.
```
add_action( 'pre_get_users', 'wpse_filter_user_query' );
function wpse_filter_user_query( $user_query ) {
global $current_screen;
if ( !is_admin() || 'users' != $current_screen->id )
return;
if( 'lastlogin' == $user_query->get( 'orderby' ) )
{
$user_query->set( 'orderby', 'meta_value' );
$user_query->set( 'meta_key', 'last_login' );
}
}
```

Now, she want to rename all default WordPress folders in app directory.
With `plugins` and `themes` we can do it easily by using `WP_PLUGIN_DIR` and [register\_theme\_directory()](https://developer.wordpress.org/reference/functions/register_theme_directory/). But, somehow, it's not easy to rename `uploads` folder.
I have tried many modifications with `UPLOADS` constant, but it can't help because custom uploads folder is always created inside `WordPress` directory.
Are there any ways to workaround this problem?

After digging around, I ended up with using [`upload_dir`](https://developer.wordpress.org/reference/hooks/upload_dir/) filter.
Here is what I tried in `functions.php` to change `uploads` to `media`. Hope it can help someone too :)
```
add_filter('upload_dir', function($uploads)
{
$custom = [];
foreach ($uploads as $key => $value) {
if ( false !== strpos($value, '/app/uploads') ) {
$custom[$key] = str_replace('/app/uploads', '/app/media', $value);
} else {
$custom[$key] = $value;
}
}
return $custom;
});
```
Many thanks to [@gmazzap](https://wordpress.stackexchange.com/users/35541/gmazzap) for the guidelines and the suggestion about `upload_dir` filter!

<p>I have this shortcode to display a loop of user avatars with order by registration date.</p>

<p>If any user role changes to <code>sticky</code> (a custom role) then that users move to top of the list. Default orderby should stay as registered for all other users in the loop. Once <code>sticky</code> user role is removed, it goes back to normal sorting.</p>
<p>I gave it quite a bit thought and maybe if i can combine two arguments in a single <code>Wp_User_Query</code> that might do the trick?</p>

Based on what you're asking and what I am understanding there is [`the_modified_date()`](https://codex.wordpress.org/Function_Reference/the_modified_date) or if you just want the value [`get_the_modified_date()`](https://codex.wordpress.org/Function_Reference/get_the_modified_date).
If you ever want the creation date you could use `post_date` and `post_date_gmt`. Several questions on this:
* [How to get post creation date?](https://wordpress.stackexchange.com/questions/177065/how-to-get-post-creation-date)
* [What is considered the post's creation date for wp\_insert\_post?](https://wordpress.stackexchange.com/questions/134512/what-is-considered-the-posts-creation-date-for-wp-insert-post)
If you are asking for a complete solution I would encourage you to search under custom post type and `wp_query`. We have several questions that are on the topic. If can make an edit with code I do not mind trying to help you further.

<p>Oddly enough I can't seem to find anyone asking this question exactly in this fashion.</p>
<p>Is it at possible to make a page be a child of a CPT? In a repeatable fashion (see below for more info) n.b. I do not mean vice versa -- which is easy enough see: <a href="https://wordpress.stackexchange.com/questions/81711/can-a-custom-post-type-have-a-parent-page">Can a custom post type have a Parent Page?</a></p>
<p>Example:</p>
<ul>
<li>I have a CPT <code>author</code> with a permalink structure: <a href="http://example.com/authors/john-doe" rel="nofollow noreferrer">http://example.com/authors/john-doe</a> </li>
<li>I want a custom Thank You post type <code>page</code> to live at <a href="http://example.com/authors/john-doe/thank-you" rel="nofollow noreferrer">http://example.com/authors/john-doe/thank-you</a> </li>
</ul>
<p>Is that possible to achieve that permalink structure in a repeatable manner? That is I'd want to have multiple arbitrary children <code>page</code> post type posts underneath the arbitrary <code>author</code> post type posts?</p>
<p>N.b. not all author pages will need to have a /authors/author-name/thank-you some many need nothing at all, some may need a different slug e.g. /authors/jane-doe/happy-birthday-greeting</p>

Oddly enough I can't seem to find anyone asking this question exactly in this fashion.
Is it at possible to make a page be a child of a CPT? In a repeatable fashion (see below for more info) n.b. I do not mean vice versa -- which is easy enough see: [Can a custom post type have a Parent Page?](https://wordpress.stackexchange.com/questions/81711/can-a-custom-post-type-have-a-parent-page)
Example:
* I have a CPT `author` with a permalink structure: <http://example.com/authors/john-doe>
* I want a custom Thank You post type `page` to live at <http://example.com/authors/john-doe/thank-you>
Is that possible to achieve that permalink structure in a repeatable manner? That is I'd want to have multiple arbitrary children `page` post type posts underneath the arbitrary `author` post type posts?
N.b. not all author pages will need to have a /authors/author-name/thank-you some many need nothing at all, some may need a different slug e.g. /authors/jane-doe/happy-birthday-greeting

I can't really think of a way that you would have a post type of page and have it be "repeatable." As Jake said, it's going to involve rewrite rules. I think the easiest way to do it would be to set up some templates for whatever these cases may be in your theme directory, and make use of query vars to populate them. So, for example:
```
function wpse_add_query_vars( $vars ){
$vars[] = "tmpl";
$vars[] = "author_slug";
return $vars;
}
add_filter( 'query_vars', 'wpse_add_query_vars' );
function wpse_add_rewrite_rule() {
add_rewrite_rule( '^authors/([^/]*)/([^/]*)', 'index.php?author_slug=$matches[1]&tmpl=$matches[2]', 'top' );
}
add_action( 'init', 'wpse_add_rewrite_rule' );
function wpse_template_include( $template ) {
if ( get_query_var( 'tmpl' ) && get_query_var( 'author_slug' ) ) {
if ( file_exists( get_template_directory() . '/' . get_query_var( 'tmpl' ) . '.php' ) ) {
$template = get_template_directory() . '/' . get_query_var( 'tmpl' ) . '.php';
}
}
return $template;
}
add_filter( 'template_include', 'wpse_template_include' );
```
I tested this and it works, but it will probably need to be tweaked for your needs. Basically, here's what's happening:
1. We register a `tmpl` query var so we can specify a template file slug as the name. We will have to create the templates we want in our theme folder.
2. We'll add a rewrite rule so that if you hit `/authors/author-name/template-name` then we can load a template (if it exists). *Make sure to flush your permalinks in settings after adding or changing any rewrite rules!*
3. Now we hook into `template_include` to see if we have the `tmpl` var set, check if we have a template in our theme directory, and return that template if we have it. So, for example, we hit `/authors/author-name/thank-you`, we will look for a `thank-you.php` template file in the theme folder and load that instead of a default template. You would have access to the author slug in the template file by using `get_query_var()`.
This is just an abstract example and will obviously need to be tweaked for your needs, but using this method you would be able to make as many of these pages as you need and maintain them right from the theme. I also didn't create an author CPT to fully test this so you may need to adjust the rewrite rule so it doesn't conflict with other things you are trying to do with the author CPT (in fact, you may not even need to use the author\_slug query var as it's probably available already from WP).
Here's some more resources:
1. [Custom Page Template Page Based on URL Rewrite](http://code.tutsplus.com/articles/custom-page-template-page-based-on-url-rewrite--wp-30564)
2. [The Rewrite API: Post Types & Taxonomies](http://code.tutsplus.com/articles/the-rewrite-api-post-types-taxonomies--wp-25488)

Where are you using **`is_single`** template tag in [WP run cycle](https://codex.wordpress.org/Plugin_API/Action_Reference) ?
Assuming you are hooking to **`init`** or **`wp`**
==================================================
Template tags are not available yet until **`template_redirect`** action. So those tags don't work for **`init`** or **`wp`**.
Best place to work with scripts or styles is on **`wp_enqueue_scripts`** which runs after **`template_redirect`** .
>
> Any idea how can we achieve that ?

There are many ways to achieve depending on the plugin we are using.
Coming to **TablePress** plugin.
`controllers/controller-frontend.php` is the place where plugin is en-queue-ing stylesheet.
```
if ( apply_filters( 'tablepress_use_default_css', true ) || TablePress::$model_options->get( 'use_custom_css' ) ) {
add_action( 'wp_enqueue_scripts', array( $this, 'enqueue_css' ) );
}
```
You can completely turn off en-queuing the stylesheet using the **`tablepress_use_default_css`** and custom css option to false, and then load them wherever you need in your custom plugin/theme.
If you dig through the file there are many conditional en-queuing is done for that plugin.
You can also dequeue style first and then enqueue wherever needed.
Sample code
===========
```
add_action('wp_enqueue_scripts','wp_228402_load_styles_conditionally',11);
function wp_228402_load_styles_conditionally() {
if(is_single()){
return; // return if not on the single post/page
}
wp_dequeue_style('tablepress-default');
}
```
Check the **priority** for the above that's the key it should be greater than default value **10**.

<p>For some reason WordPress is ignoring my thumbnail sizes and keeping thumbnails cropped proportionately instead of specific dimensions. Here is what I have in <code>functions.php</code>:</p>
<pre><code>add_image_size( 'main-thumbnail', 728, 410, true );
</code></pre>
<p>and in <code>content.php</code>:</p>
<pre><code><div class="thumbnail">
<a href="<?php the_permalink(); ?>">
<?php the_post_thumbnail( 'main-thumbnail' ); ?>
</a>
</div>
</code></pre>
<p>I added these two things and regenerated my images with the <a href="https://wordpress.org/plugins/regenerate-thumbnails/" rel="nofollow noreferrer">Regenerate Thumbnails</a> plugin, but it doesn't seem to matter. The images don't change.</p>
<p>For some reason WordPress isn't recognizing the hard crop and is keeping the images proportional, so some of my images are way taller than 410 pixels. Why is this?</p>

For some reason WordPress is ignoring my thumbnail sizes and keeping thumbnails cropped proportionately instead of specific dimensions. Here is what I have in `functions.php`:
```
add_image_size( 'main-thumbnail', 728, 410, true );
```
and in `content.php`:
```
<div class="thumbnail">
<a href="<?php the_permalink(); ?>">
<?php the_post_thumbnail( 'main-thumbnail' ); ?>
</a>
</div>
```
I added these two things and regenerated my images with the [Regenerate Thumbnails](https://wordpress.org/plugins/regenerate-thumbnails/) plugin, but it doesn't seem to matter. The images don't change.
For some reason WordPress isn't recognizing the hard crop and is keeping the images proportional, so some of my images are way taller than 410 pixels. Why is this?
|
**TL,DR;**
You are hooking early.

It's a very good thought many developers don't take this into account while developing themes/plugins.

Where are you using **`is_single`** template tag in [WP run cycle](https://codex.wordpress.org/Plugin_API/Action_Reference) ?
Assuming you are hooking to **`init`** or **`wp`**
==================================================
Template tags are not available yet until **`template_redirect`** action. So those tags don't work for **`init`** or **`wp`**.
Best place to work with scripts or styles is on **`wp_enqueue_scripts`** which runs after **`template_redirect`** .
>
> Any idea how can we achieve that ?
>
>
>
There are many ways to achieve depending on the plugin we are using.
Coming to **TablePress** plugin.
`controllers/controller-frontend.php` is the place where plugin is en-queue-ing stylesheet.
```
if ( apply_filters( 'tablepress_use_default_css', true ) || TablePress::$model_options->get( 'use_custom_css' ) ) {
add_action( 'wp_enqueue_scripts', array( $this, 'enqueue_css' ) );
}
```
You can completely turn off en-queuing the stylesheet using the **`tablepress_use_default_css`** and custom css option to false, and then load them wherever you need in your custom plugin/theme.
If you dig through the file there are many conditional en-queuing is done for that plugin.
You can also dequeue style first and then enqueue wherever needed.
Sample code
===========
```
add_action('wp_enqueue_scripts','wp_228402_load_styles_conditionally',11);
function wp_228402_load_styles_conditionally() {
if(is_single()){
return; // return if not on the single post/page
}
wp_dequeue_style('tablepress-default');
}
```
Check the **priority** for the above that's the key it should be greater than default value **10**.

<p><strong>Happy day scenario</strong>: I implement WP REST API that sends JSONs to a JavaScript client, which parses it and displays the data to the user. All is fine.</p>
<p><strong>What actually happens, inevitably</strong>: some WordPress code or plugin generates a PHP notice or warning, and the server is configured so that this garbage finds its way to the JSON response. (WP REST API <a href="https://core.trac.wordpress.org/ticket/34915" rel="nofollow">tries to avoid that</a> but for example if <code>ini_set()</code> is disallowed by server configuration, it can still happen.)</p>
<p>One way to approach is to simply blame it on the users – if their servers are configured so that they send PHP notices and warnings in production it's certainly bad. However, even the core REST infrastructure tries to support users who have badly configured servers and it's my goal as well in this case.</p>
<p>Is there a technique established for dealing with this? I can see two ways:</p>
<ol>
<li>Detect in JavaScript that the response is malformed, show some error and refuse to work.</li>
<li>Modify the actual JSON by adding some unique key to it on the server and let the JavaScript client work with that. For example, instead of the plain value <code>123</code>, it would be wrapped into an object like <code>{ "__VALID__": true, "data": 123 }</code> and the JS code would use <code>response.body.data</code> instead of <code>response.body</code>.</li>
</ol>
<p>Or is there some other approach?</p>

```

<p>I created a plugin that sets up a custom route and then loads a template file for that url. Everything works fine, except that WordPress seems to think it's a 404 even though it's correctly rendering my template.</p>
<p>For instance it says 404 in the document title and an <code>error404</code> class is added to <code><body></code></p>
<p>The custom url is domain.com/path/:id where <code>:id</code> is a dynamic value corresponding to a post id, so the URL could be domain.com/path/275. In the example below <code>some_id</code> is used as the post id variable.</p>

Manually setting `is_404 = false;` fixed my issue. However I'm not sure this is the best way to do it. I tried using the `pre_get_posts` filter instead without any luck.
Anyway, for anyone else in the same boat, you can do this to get rid of the 404 state:
```
public function add_response_template($template) {
global $wp_query;
if ( 'my_custom_url' === get_query_var( 'pagename' ) ) {
$wp_query->is_404 = false;
$template = trailingslashit( dirname( __FILE__ ) ) . 'templates/custom-page-template.php';
}
return $template;
}
```
And to update the document title (The stuff inside `<title>` in the `<head>` section) here's a snippet for making that work nicely too.
```
add_filter( 'document_title_parts', function($title_arr) {
if ( 'my_custom_url' === get_query_var('pagename') ) {
$title_arr['title'] = "Document title for my custom route";
}
return $title_arr;
}, 10, 1 );
```
If anyone knows of a better way please let me know.

<p>I read a lot about the <code>require_once</code> in stackoverflow.</p>
<p>But no anwser solved my problem.</p>
<p>I've a plugin with two files.</p>
<pre><code>dmd_main.php //main file
dmd_second.php //some WP functions
</code></pre>
<p>In my main file I've included this line:</p>
<pre><code>require_once (plugin_dir_path(__FILE__) . 'includes/dmd_second.php');
</code></pre>
<p>But on my second file I still got the errormessage:</p>
<blockquote>
<p>Call to undefined function get_option()</p>
</blockquote>
<p>I read that this is the right way to work with the wordpress functions or not?</p>
<p>I've tried a lot and this code will work if I include it in my second file:</p>

"text": "<p>Being that this is over 2 years old and all, I imagine, at least I would hope, that by now the updates have rolled out and were either handled without issues or caused a bunch of breakages that then had to be fixed. For anyone reading this, I think it does a perfect job at pointing out what Mark Kaplun eluded to in the comments of the accepted answer. There are an absurd number of plugins out there for WordPress, and it is actually very common even in very popular plugins, for a developer or whole development team to just go about doing something in so much the wrong way. This is why updates so often break sites. If you're listening, please stop it, LOL.</p>\n\n<p>In this case, as revealed in the comments, the developer has a plugin that takes direct function calls from the theme, presumably not a unique theme that he has any control over and can push updates to, hence the predicament. There is a very obvious and simple solution to the problem that would have solved it cleanly, and avoided any breakages for all future versions regardless of whether or not the functions in the theme were ever updated. Not to mention, it's also very bad practice to tell your users that they have to go through ever piece of their code in their theme where they called your function and change it now, because you couldn't be bothered to handle the function update correctly. Issuing a notice to warn users about this \"required\" change to all function calls, is the completely wrong approach to solving this problem, however the developer couldn't see that. He only knew how he wanted to try to solve it, and so he asked only the question that mattered to him, and it was also the wrong question.</p>\n\n<p>Assuming the code goes something like this:</p>\n\n<pre><code>// Plugin functions\n...\n// version 0.3\npublic function get_module($id, $name){\n // code that only handles $id and $name parameters\n}\n\n// version 0.4\npublic function get_module($module){\n // code that only handles $module as an object\n}\n\n// Theme code\n$modulator = new Plugin_Class();\n$module = $modulator->get_module(21, 'My Module');\n</code></pre>\n\n<p>The real problem has nothing to do with notices or warnings to display to the user. As soon as version 0.4 pushes out, presumably everyone who's ever used this plugin will see there site break on a totally avoidable fatal error because the plugin code is now expecting an object and they are passing it an id and a name, potentially in a lot of places throughout their code, that they now have to track down and deal with because the developer didn't bother handling it correctly. The real solution should look like this:</p>\n\n<pre><code>// Plugin functions\n...\n// version 0.4\npublic function get_module_by_id($id){\n //code to retrieve and return the module object by its ID\n return $module\n}\npublic function get_module($module){\n if(!is_object($module)){\n $module = $this->get_module_by_id($module);\n }\n // now you have your module object that you need, the rest of the code should be exactly as it would have for version 0.4\n}\n\n// Theme code\n$modulator = new Plugin_Class();\n$module = $modulator->get_module(21, 'My Module');\n// Still works in every future version of the plugin, until you decide to break it another way with an update of course.\n</code></pre>\n\n<p>As I said before, there's a time and place for notices/warnings to the user, but this isn't one of them. Think before you code, your users will appreciate it even if they don't know that they do. ;-)</p>\n"

I read a lot about the `require_once` in stackoverflow.
But no anwser solved my problem.
I've a plugin with two files.
```
dmd_main.php //main file
dmd_second.php //some WP functions
```
In my main file I've included this line:
```
require_once (plugin_dir_path(__FILE__) . 'includes/dmd_second.php');
```
But on my second file I still got the errormessage:
>
> Call to undefined function get\_option()
>
>
>
I read that this is the right way to work with the wordpress functions or not?
I've tried a lot and this code will work if I include it in my second file:
```
include_once($_SERVER['DOCUMENT_ROOT'].'wp-config.php' );
```
But this solution is realy bad.
Can somebody explain me how I can solve this problem?
EDIT:
Code from the main file:

Not possible unless you plan in advance in your plugin for such a possibility. And even if it was somehow possible you are still not likely to have any user read the message and actually understand it.
A more realistic approach is to do a two steps upgrade, in the first vesion of your plugin to maintain appropriate backward compatibility and only later you remove it from your code, giving both you the option to give proper notification, and the user time to adjust whatever he needs.

Debugging in wordpress can be a bit difficult when your first starting out, while I don't use breakpoints such as what Visual Studio offers, I can offer advice on how to debug php in general, as well as turning on the debugging output from wordpress.
First start by opening up your wp-config.php and finding the following line.
```
define('WP_DEBUG', false);
```
By default this is set to false, switch out the second parameter to true. This will enable the php notices, warning, and errors messages to be displayed in your browser.
A quick view of the [Wordpress Codex](https://codex.wordpress.org/Class_Reference/wpdb#Show_and_Hide_SQL_Errors) shows you can enable database related error messaging with a quick:
```
<?php $wpdb->show_errors(); ?>
<?php $wpdb->print_error(); ?>
```
Doing this will allow you to view the last sql query sent out, and any error it may have encounted back from MySql.
Then in general when trying to figure out what's wonky about variables or data structures I find this is always helpful:
```
<pre>
<?php print_r($arrayOrObject);
</pre>
```
Using the pre tags will spit out raw output without any html preformatting coming in, scrunching your view of associative arrays and objects. var\_dump() functions are also useful in this way.
When trying to debug something like a postback, ajax request and you want to get into the middle of it simply echo out the variables you are trying to debug and immediately issue a die() command, ex:
```
echo '<pre>';
echo var_dump($arrayOrObject);
echo '</pre>';
die();
```
For development enviorments I prefer using something along the lines of a WAMP stack (MAMP for mac osx off the top of my head.)
It's definitely useful to run a local copy of your wordpress instance on your own machine, allowing you to experiment with the above techniques as required. The above mentioned troubleshooting tips have gotten me through the last 5 years of php programming and wordpress programming. Hope you find this useful!

<p>I managed to add a custom option-select for images with </p>
<pre><code>function attachment_field_credit( $form_fields, $post ) {
$field_value = get_post_meta( $post->ID, 'first_image', true );
$isSelected1 = $field_value == '1' ? 'selected ' : '';
$isSelected2 = $field_value != '1' ? 'selected ' : '';
$form_fields['first_image'] = array(
'label' => __( 'Use as first image' ),
'input' => 'html',
'html' => "<select name='attachments[{$post->ID}][first_image]' id='attachments[{$post->ID}][first_image]'>
<option ".$isSelected1." value='1'>Yes</option>
<option ".$isSelected2." value='2'>No</option>
</select>"
);
return $form_fields;
}
add_filter( 'attachment_fields_to_edit', 'attachment_field_credit', 10, 2 );
</code></pre>
<p>Now I need to do almost the same for links. So if I click on <code>Pages -> Add New -> Insert / Edit Link</code> I get this:</p>
<p><a href="https://i.stack.imgur.com/PtiGa.png" rel="noreferrer"><img src="https://i.stack.imgur.com/PtiGa.png" alt="enter image description here"></a></p>
<p>Can I add another option-select field for those links? How to do that?</p>

I managed to add a custom option-select for images with
```
function attachment_field_credit( $form_fields, $post ) {
$field_value = get_post_meta( $post->ID, 'first_image', true );
$isSelected1 = $field_value == '1' ? 'selected ' : '';
$isSelected2 = $field_value != '1' ? 'selected ' : '';
$form_fields['first_image'] = array(
'label' => __( 'Use as first image' ),
'input' => 'html',
'html' => "<select name='attachments[{$post->ID}][first_image]' id='attachments[{$post->ID}][first_image]'>
<option ".$isSelected1." value='1'>Yes</option>
<option ".$isSelected2." value='2'>No</option>
</select>"
);
return $form_fields;
}
add_filter( 'attachment_fields_to_edit', 'attachment_field_credit', 10, 2 );
```
Now I need to do almost the same for links. So if I click on `Pages -> Add New -> Insert / Edit Link` I get this:
[](https://i.stack.imgur.com/PtiGa.png)
Can I add another option-select field for those links? How to do that?
|
The dialog HTML comes from `WP_Editors::wp_link_dialog()` but no hooks in there.
We could instead use jQuery to append the custom HTML to the link dialog and try to override e.g. the `wpLink.getAttrs()`, because it's very short ;-)
Demo example:
```
jQuery( document ).ready( function( $ ) {
$('#link-options').append(
'<div>
<label><span>Link Class</span>
<select name="wpse-link-class" id="wpse_link_class">
<option value="normal">normal</option>
<option value="lightbox">lightbox</option>
</select>
</label>
</div>' );
wpLink.getAttrs = function() {
wpLink.correctURL();
return {
class: $( '#wpse_link_class' ).val(),
href: $.trim( $( '#wp-link-url' ).val() ),
target: $( '#wp-link-target' ).prop( 'checked' ) ? '_blank' : ''
};
}
});
```
I just did a quick test and it seems to work but needs further testing and adjustments when updating links. [Here's an old hack](https://wordpress.stackexchange.com/questions/170753/modify-links-when-inserted-by-wysiwyg-editor) that I did that might need a refresh.
Update
------
It looks like you want to add the `rel="nofollow"` option to the link dialog, so let's update the above approach for that case:
We add the `rel` link attribute with:
```
/**
* Modify link attributes
*/
wpLink.getAttrs = function() {
wpLink.correctURL();
return {
rel: $( '#wpse-rel-no-follow' ).prop( 'checked' ) ? 'nofollow' : '',
href: $.trim( $( '#wp-link-url' ).val() ),
target: $( '#wp-link-target' ).prop( 'checked' ) ? '_blank' : ''
};
}
```
If the `rel` attribute is empty, then it will be automatically removed from the link in the editor.
Then we can hook into the `wplink-open` event that fires when the link dialog is opened. Here we can inject our custom HTML and update it according to the current link selection:
```
$(document).on( 'wplink-open', function( wrap ) {
// Custom HTML added to the link dialog
if( $('#wpse-rel-no-follow').length < 1 )
$('#link-options').append( '<div> <label><span></span> <input type="checkbox" id="wpse-rel-no-follow"/> No Follow Link</label></div>');
// Get the current link selection:
var _node = wpse_getLink();
if( _node ) {
// Fetch the rel attribute
var _rel = $( _node ).attr( 'rel' );
// Update the checkbox
$('#wpse-rel-no-follow').prop( 'checked', 'nofollow' === _rel );
}
});
```
where we use the following helper function, based on the `getLink()` core function, to get the HTML of the selected link:
```
function wpse_getLink() {
var _ed = window.tinymce.get( window.wpActiveEditor );
if ( _ed && ! _ed.isHidden() ) {
return _ed.dom.getParent( _ed.selection.getNode(), 'a[href]' );
}
return null;
}
```
Here's the output:
[](https://i.stack.imgur.com/LGQBo.jpg)
with the following HTML:

If I were you I would print\_r($category) and make sure it is giving you ID's and not slugs. Also, you are submitting $category to both product\_cat and brands.
If your field type were slug instead of id, and terms were exactly the same in both product\_cat and brands then this would work... though it doesn't make sense in the grand scheme of things.
Your ID's are going to be unique from each taxonomy so passing $category to both taxonomies will not work.
I hope this helped.

<p>I would like to start using the <a href="http://v2.wp-api.org/" rel="noreferrer">WordPress REST API v2</a> to query information from my site. I've noticed that when I visit an endpoint URL directly, I can see all of the data publicly. I've also seen that a lot of tutorials mention the use of test or local servers rather than live sites.</p>
<p>My questions are:</p>
<ul>
<li>Is this meant to be used on sites in production?</li>
<li>Is there a security
risk to allowing endpoints to be viewed by anyone, such as
<code>/wp-json/wp/v2/users/</code> which shows all users registered to the site?</li>
<li>Is it possible to allow only authorized users to access an endpoint?</li>
</ul>
<p>I want to make sure that I am following best practices regarding security, so any tips would be helpful. The <a href="http://v2.wp-api.org/guide/authentication/" rel="noreferrer">api docs</a> mention authentication, but I'm not sure how to prevent the URL from being accessed directly. How do others usually set up this data to be accessed by external applications without exposing too much information?</p>

Here's a very simple example of that: </p>\n\n<pre><code>class My_Private_Posts_Controller extends WP_REST_Posts_Controller {\n\n /**\n * The namespace.\n *\n * @var string\n */\n protected $namespace;\n\n /**\n * The post type for the current object.\n *\n * @var string\n */\n protected $post_type;\n\n /**\n * Rest base for the current object.\n *\n * @var string\n */\n protected $rest_base;\n\n /**\n * Register the routes for the objects of the controller.\n * Nearly the same as WP_REST_Posts_Controller::register_routes(), but with a \n * custom permission callback.\n */\n public function register_routes() {\n register_rest_route( $this->namespace, '/' . $this->rest_base, array(\n array(\n 'methods' => WP_REST_Server::READABLE,\n 'callback' => array( $this, 'get_items' ),\n 'permission_callback' => array( $this, 'get_items_permissions_check' ),\n 'args' => $this->get_collection_params(),\n 'show_in_index' => true,\n ),\n array(\n 'methods' => WP_REST_Server::CREATABLE,\n 'callback' => array( $this, 'create_item' ),\n 'permission_callback' => array( $this, 'create_item_permissions_check' ),\n 'args' => $this->get_endpoint_args_for_item_schema( WP_REST_Server::CREATABLE ),\n 'show_in_index' => true,\n ),\n 'schema' => array( $this, 'get_public_item_schema' ),\n ) );\n\n register_rest_route( $this->namespace, '/' . $this->rest_base . '/(?P<id>[\\d]+)', array(\n array(\n 'methods' => WP_REST_Server::READABLE,\n 'callback' => array( $this, 'get_item' ),\n 'permission_callback' => array( $this, 'get_item_permissions_check' ),\n 'args' => array(\n 'context' => $this->get_context_param( array( 'default' => 'view' ) ),\n ),\n 'show_in_index' => true,\n ),\n array(\n 'methods' => WP_REST_Server::EDITABLE,\n 'callback' => array( $this, 'update_item' ),\n 'permission_callback' => array( $this, 'update_item_permissions_check' ),\n 'args' => $this->get_endpoint_args_for_item_schema( WP_REST_Server::EDITABLE ),\n 'show_in_index' => true,\n ),\n array(\n 'methods' => WP_REST_Server::DELETABLE,\n 'callback' => array( $this, 'delete_item' ),\n 'permission_callback' => array( $this, 'delete_item_permissions_check' ),\n 'args' => array(\n 'force' => array(\n 'default' => true,\n 'description' => __( 'Whether to bypass trash and force deletion.' ),\n ),\n ),\n 'show_in_index' => false,\n ),\n 'schema' => array( $this, 'get_public_item_schema' ),\n ) ); \n }\n\n /**\n * Check if a given request has access to get items\n *\n * @param WP_REST_Request $request Full data about the request.\n * @return WP_Error|bool\n */\n public function get_items_permissions_check( $request ) {\n return current_user_can( 'edit_posts' );\n }\n\n}\n</code></pre>\n\n<p>You'll notice that the permissions callback <code>function get_items_permissions_check</code> uses <code>current_user_can</code> to determine whether to allow access. Depending on how you're using the API, you may need to learn more about client authentication. </p>\n\n<p>You can then register your custom post type with REST API support by adding the following arguments in <code>register_post_type</code></p>\n\n<pre><code> /**\n * Register a book post type, with REST API support\n *\n * Based on example at: http://codex.wordpress.org/Function_Reference/register_post_type\n */\n add_action( 'init', 'my_book_cpt' );\n function my_book_cpt() {\n $labels = array(\n 'name' => _x( 'Books', 'post type general name', 'your-plugin-textdomain' ),\n 'singular_name' => _x( 'Book', 'post type singular name', 'your-plugin-textdomain' ),\n 'menu_name' => _x( 'Books', 'admin menu', 'your-plugin-textdomain' ),\n 'name_admin_bar' => _x( 'Book', 'add new on admin bar', 'your-plugin-textdomain' ),\n 'add_new' => _x( 'Add New', 'book', 'your-plugin-textdomain' ),\n 'add_new_item' => __( 'Add New Book', 'your-plugin-textdomain' ),\n 'new_item' => __( 'New Book', 'your-plugin-textdomain' ),\n 'edit_item' => __( 'Edit Book', 'your-plugin-textdomain' ),\n 'view_item' => __( 'View Book', 'your-plugin-textdomain' ),\n 'all_items' => __( 'All Books', 'your-plugin-textdomain' ),\n 'search_items' => __( 'Search Books', 'your-plugin-textdomain' ),\n 'parent_item_colon' => __( 'Parent Books:', 'your-plugin-textdomain' ),\n 'not_found' => __( 'No books found.', 'your-plugin-textdomain' ),\n 'not_found_in_trash' => __( 'No books found in Trash.', 'your-plugin-textdomain' )\n );\n\n $args = array(\n 'labels' => $labels,\n 'description' => __( 'Description.', 'your-plugin-textdomain' ),\n 'public' => true,\n 'publicly_queryable' => true,\n 'show_ui' => true,\n 'show_in_menu' => true,\n 'query_var' => true,\n 'rewrite' => array( 'slug' => 'book' ),\n 'capability_type' => 'post',\n 'has_archive' => true,\n 'hierarchical' => false,\n 'menu_position' => null,\n 'show_in_rest' => true,\n 'rest_base' => 'books-api',\n 'rest_controller_class' => 'My_Private_Posts_Controller',\n 'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )\n );\n\n register_post_type( 'book', $args );\n}\n</code></pre>\n\n<p>You'll see <code>rest_controller_class</code> uses <code>My_Private_Posts_Controller</code> instead of the default controller.</p>\n\n<p>I've been finding it difficult to find good examples and explanations for using the REST API outside the <a href=\"http://v2.wp-api.org\" rel=\"noreferrer\">documentation</a>.

I would like to start using the [WordPress REST API v2](http://v2.wp-api.org/) to query information from my site. I've noticed that when I visit an endpoint URL directly, I can see all of the data publicly. I've also seen that a lot of tutorials mention the use of test or local servers rather than live sites.
My questions are:
* Is this meant to be used on sites in production?
* Is there a security
risk to allowing endpoints to be viewed by anyone, such as
`/wp-json/wp/v2/users/` which shows all users registered to the site?
* Is it possible to allow only authorized users to access an endpoint?
I want to make sure that I am following best practices regarding security, so any tips would be helpful. The [api docs](http://v2.wp-api.org/guide/authentication/) mention authentication, but I'm not sure how to prevent the URL from being accessed directly. How do others usually set up this data to be accessed by external applications without exposing too much information?

Yes. [Many sites have been already using it](https://make.wordpress.org/core/2015/07/23/rest-api-whos-using-this-thing/).

No. Server responses have nothing to do with security, nothing you can do against a blank screen or read only response.
However, If your sites allow weak passwords, there're [some problems](https://codex.wordpress.org/Brute_Force_Attacks). But it's your site's policy, REST API knows nothing about that.

Yes. You can do it by using [permission callback](https://developer.wordpress.org/rest-api/extending-the-rest-api/adding-custom-endpoints/#permissions-callback).
For example:
```
if ( 'edit' === $request['context'] && ! current_user_can( 'list_users' ) ) {
return new WP_Error( 'rest_forbidden_context', __( 'Sorry, you cannot view this resource with edit context.' ), array( 'status' => rest_authorization_required_code() ) );
}
```

This question is hard to answer because we don't know what/when is *too much information*. But we can strictly follow [API references](http://v2.wp-api.org) and [security cheatsheets](https://www.owasp.org/index.php/REST_Security_Cheat_Sheet) to avoid unwanted situation.
