<p>I need to import catalog data from external server.
The data is arranged in categories and then items.</p>
<p>the API requires the following calls:
1. Get categories
2. Get category items
3. get item data</p>
<p>this task works once a day by using a cron job.
the catalog contains about 5000 items.</p>
<p>items import is encapsulated into 3 files:
1. get cats - gets all categories
2. get category items - gets all the items, creates each item (cpt) and than calls 3
3. get item info - updates the item data (custom fields)</p>
<p>no matter what I do, I'm getting at some point error 504 Gateway Time-out.</p>

For avoid timeout best option is wp-cli.
Wp-cli is wordpress command line interface. you can export/import data using wp-cli.

<p>I have a bash script that installs and activates a theme like this: </p>
<p>wp theme install <a href="https://bitbucket.org/organization/theme/get/master.zip" rel="nofollow">https://bitbucket.org/organization/theme/get/master.zip</a> --activate</p>
<p>The problem is that it only works with public repositories, rather than private ones. If I make the repository private I get this error: </p>
<pre><code>Unpacking the package...
Warning: The package could not be installed. PCLZIP_ERR_BAD_FORMAT (-10) : Unable to find End of Central Dir Record signature
</code></pre>
<p>Is there a way I can install private repositories that I have ssh keys and passwords for?</p>

I actually figured out a way to do this. First you use wget like this:
```
wget --user username --ask-password -O path/to/output.zip https://bitbucket.org/path/to/file.zip
```
the -O flag specifies output and output.zip is where you want it to download to.
Then you can run:
```
wp theme install path/to/output.zip --activate
```
Happy days

You custom post type is **NO**T public.
Add following lines to your **register\_post\_type** `array`
```
'public' => true,
'publicly_queryable' => true,

<p>I have to do something but I just can't come up with a way to do it.<br><br>
On one hand I have created pages who are companies. So every page is a company-page.<br>
On the other hand I have created users who have a custom field added to their profile that holds the name of the company they work at.</p>
<p>No this is merely a connection between those two. So I came to the conclusion that if a company is deleted the users should be to, or at least a message should appear that the company can't be deleted because there are still users that are connected to the company.</p>
<p>I think I should hook in some sort of function to add an action to the page-delete button.</p>
<p>It's almost like if you delete a user and WP asks you if the posts the user has made are assigned to another user.</p>
<p>Can anybody tell me more about this or share some thoughts/ideas?</p>
<p>===================================<br>
UPDATE<br>
So I created the following for a custom_function to hook in the <code>before_delete_post</code><br>
NOTE: this is tested on a company page for output purposes. I use a <code>$_GET["company"]</code> request because the name is passed on in the URL. </p>
<pre><code>global $post;
$company = $_GET['company'];
$employees = $wpdb->get_results("
SELECT meta_value

*/
if(in_array($company, $employees)){
echo 'Yes';
}else{
echo 'No';
}
</code></pre>
<p>Let's say I want to delete the page <code>company_name</code>. What I do is see if this name is in the <code>usermeta</code> table. If this is true the delete function should not be executed. If not the page can be deleted.</p>
<p>But this just keeps echo-ing <code>No</code> while it should echo <code>Yes</code> because I know the pagename is <code>company_name</code> and it is in the employee list. So I should have a match.</p>

On one hand I have created pages who are companies. So every page is a company-page.
On the other hand I have created users who have a custom field added to their profile that holds the name of the company they work at.
No this is merely a connection between those two. So I came to the conclusion that if a company is deleted the users should be to, or at least a message should appear that the company can't be deleted because there are still users that are connected to the company.
I think I should hook in some sort of function to add an action to the page-delete button.
It's almost like if you delete a user and WP asks you if the posts the user has made are assigned to another user.
Can anybody tell me more about this or share some thoughts/ideas?
===================================
UPDATE
So I created the following for a custom\_function to hook in the `before_delete_post`
NOTE: this is tested on a company page for output purposes. I use a `$_GET["company"]` request because the name is passed on in the URL.
```
global $post;
$company = $_GET['company'];
$employees = $wpdb->get_results("
SELECT meta_value
FROM $wpdb->usermeta
WHERE meta_key = 'company'
AND meta_value='$company'"
);
/*
output $employees:
[0] => stdClass Object
(
[meta_value] => company_name
)
*/
if(in_array($company, $employees)){
echo 'Yes';
}else{
echo 'No';
}
```
Let's say I want to delete the page `company_name`. What I do is see if this name is in the `usermeta` table. If this is true the delete function should not be executed. If not the page can be deleted.
But this just keeps echo-ing `No` while it should echo `Yes` because I know the pagename is `company_name` and it is in the employee list. So I should have a match.

It gives an array with objects. So `in_array()` won't find anything, you have to convert it before. After you get the results from wbdb:
```
$employees_array = array();
foreach($employees as $employee) {
$employees_array[] = $employee->meta_value;
}
if(in_array($company, $employees_array)) {
...
}
```

I created a custom taxonomy using following code.
```
add_action( 'init', 'schedule_day_tax_func' );
function schedule_day_tax_func() {
register_taxonomy(
'schedule_day_taxonomy',
'schedule',
array(
'hierarchical' => true,
'label' => 'Day',
'query_var' => true,
'orderby' => 'ID',
)
);
}
```
after I added some terms from the admin panel, the TERMS displayed in `alphabetica`l order in admin panel.
[](https://i.stack.imgur.com/vbbZN.jpg)
I want those in orderby `ID` or by the `entered` order.
How can I do that?
|
Method #1 - Modifying the query arguments
-----------------------------------------
If we want to modify the *term order* for the `schedule_day_taxonomy` term checklist, on the single `schedule` cpt edit screen, then we can use the following setup:
```
add_action( 'load-post.php', function()
{
add_filter( 'wp_terms_checklist_args', 'wpse_terms_checklist_args' );
} );
function wpse_terms_checklist_args( $args )
{
// Target the 'schedule' custom post type edit screen
if( 'schedule' === get_current_screen()->id )
add_filter( 'get_terms_args', 'wpse_terms_args', 10, 2 );
return $args;
}
function wpse_terms_args( $args, $taxonomies )
{
// Target the 'all' tab in the 'schedule_day_taxonomy' terms check list
if(
isset( $args['get'] )
&& 'all' === $args['get']
&& isset( $taxonomies[0] )
&& 'schedule_day_taxonomy' === $taxonomies[0]
) {
// Modify the term order
$args['orderby'] = 'ID'; // <-- Adjust this to your needs!
$args['order'] = 'ASC'; // <-- Adjust this to your needs!
// House cleaning - Remove the filter callbacks
remove_filter( current_filter(), __FUNCTION__ );
remove_filter( 'wp_terms_checklist_args', 'wpse_terms_checklist_args' );
}
return $args;
}
```
Another possibility would be to combine this into a single `get_terms_args` filter callback.
To get the following day order:
```
Sun, Mon, Tue, Wed, Thu, Fri, Sat
```
we could modify the corresponding term slugs and use:
```
// Modify the term order
$args['orderby'] = 'slug';
$args['order'] = 'ASC';
```
Method #2 - Re-ordering the query results
-----------------------------------------
If we don't want to modify the slug, then here's another approach.
We can re-order the resulting terms array, in the same order as the localized weekdays.
```
add_filter( 'wp_terms_checklist_args', function( $args )
{
add_filter( 'get_terms', 'wpse_get_terms', 10, 3 );
return $args;
} );
function wpse_get_terms( $terms, $taxonomies, $args )
{
if( isset( $taxonomies[0] )
&& 'schedule_day_taxonomy' === $taxonomies[0]
&& 'schedule' === get_current_screen()->id
) {
$newterms = [];
foreach( (array) $GLOBALS['wp_locale']->weekday as $day )
{
foreach( (array) $terms as $term )
{
if( $term->name === $day )
$newterms[] = $term;
}
}
remove_filter( current_filter(), __FUNCTION__ );
if( 7 === count( $newterms ) )
$terms = $newterms;
}
return $terms;
}
```
We could also replace
```
$GLOBALS['wp_locale']->weekday
```
with a custom weekdays array, ordered in a custom way.
Here's the *English* version:
[](https://i.stack.imgur.com/S1YYp.jpg)
and here's the *Icelandic* version:
[](https://i.stack.imgur.com/BYtjD.jpg)
Method #3 - Custom SQL ordering
-------------------------------
We could modify the SQL ordering with the `get_terms_orderby` filter, with a `CASE/WHEN/THEN` setup.
Hopefully you can adjust this to your needs.

It's informative to check out the `/wp-admin/post.php` file, that contains the `edit_post()` function that calls `wp_update_post()`, which is a `wp_insert_post()` wrapper.
Here's a skeleton for saving the assigned category terms:
```
/**
* Saving assigned category terms (skeleton)
*/
add_action( 'admin_action_editpost', function()
{
add_filter( 'wp_insert_post_data', function( $data, $parr )
{
add_action( 'save_post_post', function( $post_ID, $post ) use ( $parr )
{
if(
isset( $parr['_wpnonce'] )
&& wp_verify_nonce( $parr['_wpnonce'], 'update-post_' . absint( $post_ID ) )
&& current_user_can( 'manage_categories' )
&& function_exists( 'wpse_save_assigned_cats' )
&& ! did_action( 'wpse_save_assigned_cats' )
) {
wpse_save_assigned_cats( $post_ID, $parr );
do_action( 'wpse_save_assigned_cats' );
}
}, 10, 2 );
return $data;
}, 10, 2 );
} );
```
where our helper function `wpse_save_assigned_cats()` is based on the `edit_post()` function:
```
/**
* Helper function based on the cat/tax handling of the edit_post() functions
*/
function wpse_save_assigned_cats( $post_ID, $parr )
{
if( ! empty( $parr['tax_input']['category'] ) && $post_ID > 0 )
{
// Change the comma seperated string of category names,
// in $parr['tax_input']['category'], to an array of cats id
$input_cats = explode( ',', trim( $parr['tax_input']['category'], " \n\t\r\0\x0B," ) );
$clean_cats = array();
foreach ( $input_cats as $cat_name )
{
// Don't allow empty categories
if ( empty( $cat_name ) )
continue;
// Check if there already exists such a category
$_cat = get_terms( 'category', array(
'name' => $cat_name,
'fields' => 'ids',
'hide_empty' => false,
) );
// The category name already exists
if ( ! empty( $_cat ) )
{
// Collect the (first) category id
$clean_cats[] = intval( $_cat[0] );
}
else
{
// Create the category, since it doesn't exists
$cat_id = wp_create_category( $cat_name );
// Collect the category id
if( $cat_id > 0 )
$clean_cats[] = $cat_id;
}
}
// Current post's category IDs
$cats = (array) wp_get_post_categories( $post_ID, array( 'fields' => 'ids' ) );
// Unique array of category IDs
$post_categories = array_unique( array_merge( $cats, $clean_cats ) );
// Assign the categories to the current post
wp_set_post_categories( $post_ID, $post_categories );
}
}
```
Previous Answer:
----------------
Here's my Friday answer, so it might need some testing ;-)
I just re-registered the `category` taxonomy as *non-hierarchical* with:
```
'hierarchical' => false,
```
Then the category box showed up like this:
[](https://i.stack.imgur.com/JgAEC.jpg)
and saving terms worked as expected.
Here's my testing code snippet, so you can try it further:
```
add_action( 'init', function()
{
global $wp_rewrite;
register_taxonomy( 'category', 'post', array(
'hierarchical' => false,
'query_var' => 'category_name',
'rewrite' => array(
'hierarchical' => true,
'slug' => get_option('category_base') ? get_option('category_base') : 'category',
'with_front' => ! get_option('category_base') || $wp_rewrite->using_index_permalinks(),
'ep_mask' => EP_CATEGORIES,
),
'public' => true,
'show_ui' => true,
'show_admin_column' => true,
'_builtin' => true,
'labels' => array(
'name' => __( 'Categories' ),
'singular_name' => __( 'Category' ),
'search_items' => __( 'Search Categories' ),
'popular_items' => null,
'all_items' => __( 'All Categories' ),
'edit_item' => __( 'Edit Category' ),
'update_item' => __( 'Update Category' ),
'add_new_item' => __( 'Add New Category' ),
'new_item_name' => __( 'New Category Name' ),
'separate_items_with_commas' => null,
'add_or_remove_items' => null,
'choose_from_most_used' => null,
),
'capabilities' => array(
'manage_terms' => 'manage_categories',
'edit_terms' => 'manage_categories',
'delete_terms' => 'manage_categories',
'assign_terms' => 'edit_posts',
),
) );
} );
```

I have created custom post type `gallery`.
How change the `previous post` and `next post` link to point to the current Authors posts only?
The Previous and Next Post link should not display if there are no more posts
[](https://i.stack.imgur.com/Z4tQ2.png)
|
To limit post navigation to the same author and category, locate the link-template.php file in the /wp-includes/ folder, and edit using your favorite text editor (Notepad++ for me). In this file you will alter four functions. Locate the following lines in the link-template.php file:
```
function previous_post_link($format='« %link', $link='%title', $in_same_cat = false, $excluded_categories = '') {
adjacent_post_link($format, $link, $in_same_cat, $excluded_categories, true);
}
```
Change that to the following:
```
function previous_post_link($format='« %link', $link='%title', $in_same_cat = false, $excluded_categories = '', $is_author = false) {
adjacent_post_link($format, $link, $in_same_cat, $excluded_categories, true, $is_author);
}
```
Below the previous lines of code you should find this:
```
function next_post_link($format='%link »', $link='%title', $in_same_cat = false, $excluded_categories = '') {
adjacent_post_link($format, $link, $in_same_cat, $excluded_categories, false);
}
```
Change that to the following:
```
function next_post_link($format='%link »', $link='%title', $in_same_cat = false, $excluded_categories = '',$is_author = false) {
adjacent_post_link($format, $link, $in_same_cat, $excluded_categories, false, $is_author);
}
```
These changes are small. You should notice that the only changes made were adding $is\_author = false to the function parameters and $is\_author to the call to adjacent\_post\_link call.
On the next function you'll be adding another parameter and adjust the SELECT query that is pulling in the next/previous post. Locate the following line that should look something like this:
```
function get_adjacent_post($in_same_cat = false, $excluded_categories = '', $previous = true) {
...
}
```
This block is fairly long so I'm only covering what's being changed. On this line add the same parameter as before ($is\_author = false):
```
function get_adjacent_post($in_same_cat = false, $excluded_categories = '', $previous = true, $is_author = false) {
...
}
```
Next, in this same function find the $where variable as shown below (roughly 50 lines into the function).
```
$where = apply_filters( "get_{$adjacent}_post_where", $wpdb->prepare("WHERE p.post_date $op %s AND p.post_type = %s AND p.post_status = 'publish' $posts_in_ex_cats_sql", $current_post_date, $post->post_type), $in_same_cat, $excluded_categories );
```
What we want to do next is alter this variable so it retains the author only when $is\_author is true. To do this test the boolean value of $is\_author and tack a little extra on the end of the $where variable.
```
$where = apply_filters( "get_{$adjacent}_post_where", $wpdb->prepare("WHERE p.post_date $op %s AND p.post_type = %s AND p.post_status = 'publish' $posts_in_ex_cats_sql", $current_post_date, $post->post_type), $in_same_cat, $excluded_categories );
if($is_author)
$where .= " AND p.post_author='".$post->post_author."'";
```
For the final change in the link-template.php file locate the following function:
```
function adjacent_post_link($format, $link, $in_same_cat = false, $excluded_categories = '', $previous = true) {
if ( $previous && is_attachment() )
$post = & get_post($GLOBALS['post']->post_parent);
else
$post = get_adjacent_post($in_same_cat, $excluded_categories, $previous);
```
Alter this function by the $is\_author in the adjacent\_post\_link function and adding it to the get\_adjacent\_post call:
```
function adjacent_post_link($format, $link, $in_same_cat = false, $excluded_categories = '', $previous = true, $is_author = false) {
if ( $previous && is_attachment() )
$post = & get_post($GLOBALS['post']->post_parent);
else
$post = get_adjacent_post($in_same_cat, $excluded_categories, $previous, $is_author);
```
Now you're ready to use this new option in the theme files. To "activate" the retain author function use something like this in your single.php:
```
<?php previous_post_link( '%link', '' . _x( '←', 'Previous post link', 'twentyten' ) . ' %title','true','','true' ); ?>
<?php next_post_link( '%link', '%title ' . _x( '→', 'Next post link', 'twentyten' ) . '','true','','true' ); ?>
```
Setting the last value to "true" activates the retain author function for that link. This will ensure the link stays within the same author as well as the same date.

<p>I have some dynamic templates where I have to customize the canonical links. </p>
<p>According to Yoast documentation the hook to use is <code>wpseo_canonical</code></p>
<p>I have two functions pointing to different pages IDs:</p>
<pre><code>add_filter('wpseo_canonical', 'listpagecanonical');
function listpagecanonical($string) {
if (is_page(1)){
//I do my stuff here
return 'http://canonicalurl.com'
}
}
</code></pre>
<p>Then I have another:</p>
<pre><code>add_filter('wpseo_canonical', 'detailpagecanonical');
function detailpagecanonical($string) {
if (is_page(2)){
//I do my stuff here
return 'http://canonicalurl2.com'
}
}
</code></pre>
<p>The problem I'm having is that if both filters have the same priority, like the example, they simply don't work, if I add 10, 1 to the first it will work but 2nd wont. If I add 20, 1 to second, it will work but first will stop working and so on.</p>
<p>Is there any way to do this in a way that they don't override themselves like that?</p>

Filters should be returned even if your condition fails. You are currently just returning the output when your condition is met, not when it fails.
`return $string;` at the end of each function should solve your issue.
EXAMPLE
-------
```
add_filter('wpseo_canonical', 'listpagecanonical');
function listpagecanonical($string) {
if (is_page(1)){
//I do my stuff here
return 'http://canonicalurl.com'
}
return $string;
}

I have tried using `sanitize_text_field()` and `esc_attr()` to filter checkbox data when saving their values to the database, but it is causing the data not being saved.
What is causing it and what's the correct way to filter input `checkbox` and `radio`?
|
I would use the filter\_var() function. It has some predefined filters that you can use depending on what kind of data you are expecting such as string, number, etc.
So to sanitize for a number:
```
$sanitizedNum = filter_var($yourVar, FILTER_SANITIZE_NUMBER_INT);
```
For a string you would just change "\_NUM\_INT" to "\_STRING".
Wrap those in a custom function then.

Display author's avatar and name in single page sidebar. Add this code in sidebar.php or single.php
```
if ( is_singular( 'post' ) ) {
echo get_avatar( get_the_author_meta( 'user_email' ), 75 );
echo get_the_author_meta( 'display_name' );

```
Here 75 number is the avatar size.
I hope it will help you.

I am trying to add a function to my child theme to append the currently logged user as a parameter. For example, when the user test1 logs in and clicks on the following page:
```
http://www.example.com/my-wishlist
```
I want her to be redirected automatically to
```
http://www.example.com/my-wishlist/?user=test1
```
So far I did the following but it ends in a loop:
```
$current_user = wp_get_current_user();
if ( is_user_logged_in() ) {
wp_redirect( 'http://www.example.com/my-wishlist/?user='.$current_user->user_login );
exit;
}
```
I would appreciate some help. Thank you

Use [add\_query\_arg](https://developer.wordpress.org/reference/functions/add_query_arg/) to make sure the url is created the right way. How is the wishlist link outputted? Trough wp\_nav\_menu? I would add it to the link on creation, so you don't have to use wp\_redirect.

<p>I am on Archive Page of a custom post type <code>gallery</code>.</p>
<p>I have introduced custom permalink variable - <code>author_id</code>.</p>
<p>Lets say i get the permalink variable in <code>$perm_author_id</code>. I want to compare <code>$perm_author_id</code> and <code>get_the_author_meta(ID)</code> and then display the posts if they are equal.</p>
<p>How can I limit posts displayed on the archive page on to those posts posted by author whose <code>author_id</code> is present in permalink?</p>

I am on Archive Page of a custom post type `gallery`.
I have introduced custom permalink variable - `author_id`.
Lets say i get the permalink variable in `$perm_author_id`. I want to compare `$perm_author_id` and `get_the_author_meta(ID)` and then display the posts if they are equal.
How can I limit posts displayed on the archive page on to those posts posted by author whose `author_id` is present in permalink?

```
function comment_author_id($query) {

<p>I want to know how I can change the structure of the permalink to my desired one before saving or publishing my post in Wordpress?<br/>

Finally, I found my answer on my own.

//add our action

function my_save_post($post_id, $post){
//if it is just a revision don't worry about it
if (wp_is_post_revision($post_id))
return false;
//if the post is an auto-draft we don't want to do anything either
if($post->post_status != 'auto-draft' ){
// unhook this function so it doesn't loop infinitely
remove_action('save_post', 'my_save_post' );
//this is where it happens -- update the post and change the post_name/slug to the post_title
wp_update_post(array('ID' => $post_id, 'post_name' => str_replace(' ', '-', $_POST['post_title'])));
//re-hook this function
add_action('save_post', 'my_save_post' );
}

<p>I am working on setting up the customizer for my theme. I have all of the sections and controls I need, but now I am trying to make some of them only show on certain pages.</p>
<p>My first stop is the sections that relate only to the home page. I read <a href="https://codex.wordpress.org/Class_Reference/WP_Customize_Manager/add_section" rel="nofollow" title="here">here</a> that I can add an argument called "active_callback" tp the arguments object and pass it a check function such as <code>is_front_page</code> or <code>is_home</code>.</p>
<p>Seemed easy, until I tried it and it didn't work. I've tried everything I could think of (this is my first foray into WordPress), so now I am coming to you all hoping you can answer my question</p>
<p>I am customizing the customizer in <code>functions.php</code> like such:</p>
<pre><code>add_action( 'customize_register', 'ablogs_theme_customizer' );

));
}
</code></pre>
<p>If I take off the active callback argument, it shows up just fine, but on every page while customizing. I really need this to only show up on the home page. I am not using a static front page. I am running a custom <code>front-page.php</code> file that acts as the front page, so I am guessing that should count as both <code>front-page</code> and <code>home</code> when checking for those values, both of which I have tried.</p>

I am working on setting up the customizer for my theme. I have all of the sections and controls I need, but now I am trying to make some of them only show on certain pages.
My first stop is the sections that relate only to the home page. I read [here](https://codex.wordpress.org/Class_Reference/WP_Customize_Manager/add_section "here") that I can add an argument called "active\_callback" tp the arguments object and pass it a check function such as `is_front_page` or `is_home`.
Seemed easy, until I tried it and it didn't work. I've tried everything I could think of (this is my first foray into WordPress), so now I am coming to you all hoping you can answer my question
I am customizing the customizer in `functions.php` like such:
```
add_action( 'customize_register', 'ablogs_theme_customizer' );
function ablogs_theme_customizer($wp_customize) {
$wp_customize->add_section( 'home-page-slider-settings', array(
'title' => "Slider Settings",
'priority' => 0,
'active_callback' => 'is_front_page'
));
}
```
If I take off the active callback argument, it shows up just fine, but on every page while customizing. I really need this to only show up on the home page. I am not using a static front page. I am running a custom `front-page.php` file that acts as the front page, so I am guessing that should count as both `front-page` and `home` when checking for those values, both of which I have tried.
Can anybody help me out here

The problem was I had multiple loops that each had different queries on the front page. After making sure to reset them each time, this problem resolved itself.
For instance, my new query and loop looks like this:
```
query_posts( array(
'category_name'=>"Cloud, Customer Engagement, Developers, Executive Thought Leadership, Networking, Services, Solutions, Team Engagement",
'showposts'=>8,
'order'=>DESC
));
// Start the loop
if ( have_posts() ) : while ( have_posts() ) : the_post();
echo '<div class="post-card-wrap">';
// Get the card
get_category_post_card($post);
echo '</div>';
// End the loop
endwhile; endif;
// Reset the query
wp_reset_query();
```

new example with custom post type \*\*
```
function projectPost_remove_extra_data( $data, $post, $context ) {

unset( $data['status'] );
return $data;
}
add_filter( 'json_prepare_project', 'projectPost_remove_extra_data', 12, 3 );
```
|
If possible, only the examples shown in internet is:
```
function qod_remove_extra_data($data, $post, $context) {
// We only want to modify the 'view' context, for reading posts
if ($context !== 'view' || is_wp_error($data)) {
return $data;
}
// Here, we unset any data we do not want to see on the front end:
unset($data['author']);
unset($data['status']);
// Continue unsetting whatever other fields you want return $ data;
}
add_filter('json_prepare_post', 'qod_remove_extra_data', 12, 3);
```
and right is:
```
function qod_remove_extra_data($data, $post, $context) {
// We only want to modify the 'view' context, for reading posts
if ($context !== 'view' || is_wp_error($data)) {
unset ( $data->data['excerpt']); //Example
unset ($data->data['content']); //Example
unset ($data->data['name field to remove']);
//or
unset ($data->data['name field to remove']['name subfield if you only want to delete the sub-field of field']);
return $data;
}
}
add_filter('rest_prepare_post', 'qod_remove_extra_data', 12, 3);
```
IMPORTANT:
Is:
```
add_filter('rest_prepare_post', 'qod_remove_extra_data', 12, 3);
```
Not:
```
add_filter('json_prepare_post', 'qod remove extra_data', 12, 3); //WRONG (No underscores)
```
If is Custom Post Type:
```
add_filter('rest_prepare_{$post_type}', 'qod_remove_extra_data', 12, 3);
```
EXAMPLE: Name post type = product;
```
add_filter('rest_prepare_product', 'qod_remove_extra_data', 12, 3);
```
With this code can remove the fields that you want the JSON. By using rest\_prepare}\_{$ post\_type decide that you eliminated every post\_type fields, thus only affected the post\_type you want and not all.

i want to add a page with html data to show form and get input from user,store it to database and after successful query show next page with massage that the data is inserted successfully.
|
If possible, only the examples shown in internet is:
```
function qod_remove_extra_data($data, $post, $context) {
// We only want to modify the 'view' context, for reading posts
if ($context !== 'view' || is_wp_error($data)) {
return $data;
}
// Here, we unset any data we do not want to see on the front end:
unset($data['author']);
unset($data['status']);
// Continue unsetting whatever other fields you want return $ data;
}
add_filter('json_prepare_post', 'qod_remove_extra_data', 12, 3);
```
and right is:
```
function qod_remove_extra_data($data, $post, $context) {
// We only want to modify the 'view' context, for reading posts
if ($context !== 'view' || is_wp_error($data)) {
unset ( $data->data['excerpt']); //Example
unset ($data->data['content']); //Example
unset ($data->data['name field to remove']);
//or
unset ($data->data['name field to remove']['name subfield if you only want to delete the sub-field of field']);
return $data;
}
}
add_filter('rest_prepare_post', 'qod_remove_extra_data', 12, 3);
```
IMPORTANT:
Is:
```
add_filter('rest_prepare_post', 'qod_remove_extra_data', 12, 3);
```
Not:
```
add_filter('json_prepare_post', 'qod remove extra_data', 12, 3); //WRONG (No underscores)
```
If is Custom Post Type:
```
add_filter('rest_prepare_{$post_type}', 'qod_remove_extra_data', 12, 3);
```
EXAMPLE: Name post type = product;
```
add_filter('rest_prepare_product', 'qod_remove_extra_data', 12, 3);
```
With this code can remove the fields that you want the JSON. By using rest\_prepare}\_{$ post\_type decide that you eliminated every post\_type fields, thus only affected the post\_type you want and not all.

I've a theme which loads 'Open Sans' from Google Fonts. Our site is using SSL & we're using a `$protocol://` to render the font URL
However, I noticed that, some plugin/(s) probably adding 3 different fonts from Google Fonts, & they're being loaded using `http://` & that throws error such as:
`Blocked loading mixed active content "http://fonts.googleapis.com/css?family=Lato:300,400,700"`
**Question:** How do we disable fonts loaded from plugins, on the frontend, since they're not used in visual sense of the website
Thanks in advance :)

If the fonts are loaded from a plugin, a hook will have to be used to insert them, you can disable the hook, but you'll need to know where it's coming from. Mostly because you'll need the handle of the script.
There are quite a few different ways it could be done so I'll try to give an example of one way it may be done, but there's a good chance you'll need to do some hunting yourself.
The plugin could be (ideally is) loading it directly with [`wp_enqueue_style()`](http://codex.wordpress.org/Function_Reference/wp_enqueue_style), lucky for us there's a function for reversing that action [`wp_dequeue_style()`](http://codex.wordpress.org/Function_Reference/wp_dequeue_style), you just need to make sure you hook in at the right time and you can remove it. In most cases this is done in the [`wp_enqueue_scripts`](http://codex.wordpress.org/Plugin_API/Action_Reference/wp_enqueue_scripts) hook. It's possible they have set a high priority to make it load late, but that's not usually necessary, you may need to find exactly how they do it to be sure.
somewhere in the plugin may be a few lines of code something like:
```
add_action( 'wp_enqueue_scripts', 'plugin_setup_styles' );
function plugin_setup_styles() {
// it may not be quite this simple, depending on what the plugin is doing
wp_register_style( 'plugin-google-font-lato', 'http://fonts.googleapis.com/css?family=Lato:300,400,700' );
wp_enqueue_style( 'plugin-google-font-lato' );
}
```
possible solution, should work from functions.php:
```
add_action( 'wp_enqueue_scripts', function() {
wp_dequeue_style( 'plugin-google-font-lato' );
}, 99 );
```
Basically, you're going to need to know the handle of the script as it is registered, `grep` is great for this `$ grep -R wp_enqueue_style wp-content/plugins/` as a start. But you may get better results searching for Lato `$ grep -Rn Lato wp-content/plugins/`

How can i limit comments displayed on the page - `reviews` by `author_id`.
Lets say that the `author_id` to limit to is in variable `$author_id_to_limit`.
Please tell me how to hook the function to do so.
I would even like to know how to edit the no of post with this cuurent query.
|
The `pre_get_comments` hook
---------------------------
Note that the single post's comments are fetched with `get_comments()`, within the `comment_template()` function.
The `get_comments()` function is just a `WP_Comment_Query` object wrapper, so we can restrict the comment query with the `pre_get_comments` hook.
Example #1
----------
Here's a simple `user_id` restriction example:
```
! is_admin() && add_action( 'pre_get_comments', function( \WP_Comment_Query $q )
{
if( $uid = get_query_var( 'author_id_to_limit' ) )
$q->query_vars['user_id'] = (int) $uid;
});
```
where you might add further constraints, so you don't modify other comment lists.
Example #2
----------
We could restrict it more with:
```
// Let's begin where the main loop starts:
add_action( 'loop_start', function( \WP_Query $q )
{
// Target the main loop
if( ! in_the_loop() )
return;
// Modify the get_comments() call
add_action( 'pre_get_comments', function( \WP_Comment_Query $q )
{
if(
$uid = get_query_var( 'author_id_to_limit' ) // Get the user input
&& ! did_action( 'wpse_mods' ) // Run this only once
) {
// Set the comment user id
$q->query_vars['user_id'] = (int) $uid;
// Activate the temporary action
do_action( 'wpse_mods' );
}
});
});
```
i.e. we want to target the first `get_comments()` call after the main loop starts.
You might use other hooks, some themes have specific hooks that might be easier to target.
Modify the comments count accordingly
-------------------------------------
If we want to modify the displayed comments number, then we could use the `get_comments_number` filter.
The `get_comments_number()` function uses the `comment_count` property of the $post object, that originates from the `wp_posts` table. So that will not help us here.
We can instead re-use the comments query, to update the comment number, exactly when our temporary `wpse_mods` action as fired only once (you might have to adjust that to your needs)
```
! is_admin() && add_action( 'the_comments', function( $comments, \WP_Comment_Query $q )
{
$request = $q->request;
add_filter( 'get_comments_number', function( $number ) use ( $request )
{
// Override the comments number after our previous modifications
if( 1 === did_action( 'wpse_mods' ) )
{
global $wpdb;
// Modify the comments query to our needs:
$number = $wpdb->get_var(
str_replace(
'SELECT * ',
'SELECT COUNT(*) ',
$request
)
);
}
return $number;
} );
return $comments;
}, 10, 2 );
```

<p>I know I'm doing something that's been done 1000's of times before in WordPress, but struggling to get the terms to find it on the Interwebs.</p>
<p>I've got a custom category template page and have a while loop that shows the first 5 results (of which there are more than 5).</p>
<p>How do I output something within my while that shows the relative position in the results and the total number:</p>
<p>I know how to get the post count:</p>
<pre><code><?php
$catcount = new WP_Query( 'cat=4&posts_per_page=-1' );
?>
</code></pre>
<p>But not sure how to setup the pagination and the relative results, meaning</p>
<p>Results 1-10 of <code><?php echo $total->found_posts; ?></code></p>
<p>How do I get the results values 1 of 2 and then create pagination for subsequent pages?</p>

I know I'm doing something that's been done 1000's of times before in WordPress, but struggling to get the terms to find it on the Interwebs.
I've got a custom category template page and have a while loop that shows the first 5 results (of which there are more than 5).
How do I output something within my while that shows the relative position in the results and the total number:
I know how to get the post count:
```
<?php
$catcount = new WP_Query( 'cat=4&posts_per_page=-1' );
?>
```
But not sure how to setup the pagination and the relative results, meaning
Results 1-10 of `<?php echo $total->found_posts; ?>`
How do I get the results values 1 of 2 and then create pagination for subsequent pages?
|
it's been a long time, I had exact the same task and here is the solution
```
$from = ($query->query_vars['posts_per_page'] * $paged) - ($query->query_vars['posts_per_page'] - 1);
if(($query->query_vars['posts_per_page'] * $paged) <= ($query->found_posts)){
$to = ($query->query_vars['posts_per_page'] * $paged);
}else{
$to = $query->found_posts;
}
if($from == $to){
$from_to = $from;
}else{
$from_to = $from.' - '.$to;
}
```
It's not the perfect code, but it works in most of situation.
Have a nice day!)

Rather than altering the core file [`./wp-includes/comment-template.php`](https://core.trac.wordpress.org/browser/tags/4.3/src/wp-includes/comment-template.php#L1113), a more maintainable solution would be to create [a `comments.php` template file](https://codex.wordpress.org/Theme_Development#Comments_.28comments.php.29) within your custom theme (or [a child theme](https://codex.wordpress.org/Child_Themes) of your current theme if was developed by a third-party) and use [WP\_Comment\_Query](https://codex.wordpress.org/Class_Reference/WP_Comment_Query) in it to specify your new arguments. Use the `number` and `offset` arguments to specify a desired range of comments.
**Template File `./wp-content/themes/wpse202457_theme/comments.php`:**
```
<?php
$author_id = get_query_var( 'author_id', '' );
$comments = array();
if( $author_id != '' ) {
$comment_args = array(
'order' => 'ASC',

'status' => 'approve',
'meta_key' => 'custom_author_id',
'meta_value' => $author_id,
'number' => 20, // Retrieve 20 comments...
'offset' => 40 // ...starting from the 40th comment.
);
$comment_query = new WP_Comment_Query;
$comments = $comment_query->query( $comment_args );
}
if( ! empty( $comments ) ) {
// The Comments Loop
foreach( $comments as $comment ) {
echo( '<p>' . $comment->comment_content . '</p><br/><br/>' );
}
}
else {
echo( '<p>No comments found</p>' );
}
?>
```
Check out [this excellent question](https://wordpress.stackexchange.com/questions/184449/wp-comment-query-pagination-delving-into-the-unknown) for the way to handle breaking comments up into pages (pagination) using the `number` and `offset` arguments dynamically. Dig into other themes' `comments.php` template file for some example markup.
Instead of creating a new theme template, you could alternately place your substitute comments template in a plugin, and use the [`comments_template` filter](https://codex.wordpress.org/Function_Reference/comments_template) to redirect comment template inclusions to it:
**Plugin File `./wp-content/plugins/wpse202457_comments_plugin/wpse202457CommentsPlugin.php`:**
```
function wpse202457_comments_template( $comment_template ) {
// Redirect ALL comment template inclusions to "./wp-content/plugins/wpse202457_comments_plugin/comments.php"
return dirname(__FILE__) . '/comments.php';
}
add_filter( 'comments_template', 'wpse202457_comments_template' );
```
---
ADDENDUM
--------
In response to the comments, as @Rarst suggested, the `get_comments_query()` function will only return the number of comments recorded for the post object displayed in the main query.
To get the number of comments for your altered query, simply `count()` the results of the query, i.e.:
```
$comment_query = new WP_Comment_Query;
$comments = $comment_query->query( $comment_args );
$comment_count = count( $comments );
```
**However**, if you are using the `number` argument to specify the number of comments you wish to retrieve, then `$comment_count` will always be equal to, or less than `number`. To get the total number of comments that match your arguments, you will either need to omit the `number` argument and `count()` the results, or set the `count` argument to `true`, in which case the query will return the number of matching comments without returning the comments themselves:
```
$author_id = get_query_var( 'author_id', 1 );
$comment_args = array(
'status' => 'approve',
'meta_key' => 'custom_author_id',
'meta_value' => $author_id,
'count' => true // Return the NUMBER of matching comments, not the matching comment objects themselves
);
$comment_query = new WP_Comment_Query;
$comment_count = $comment_query->query( $comment_args );
```
If you don't plan on doing anything else with the `WP_Comment_Query` object, you may want to create some convenience functions and put them in your plugin, or your custom theme's `functions.php` for quick access. Something along the lines of:
```
// Get comments with a custom_author_id meta-value of $author_id
function wpse202471_get_author_comments( $author_id = null, $args = array() ) {
// If an author id was not passed, see if there's one in the query vars
if( ! isset( $author_id ) )
$author_id = get_query_var( 'author_id', null );
// If no author id was provided, return a negative result
if( ! isset( $author_id ) ) {
if( isset( $args[ 'count' ] ) && $args[ 'count' ] )
return 0;
return array();
}
// Merge query argument arrays
$comment_args = array_merge(
array( // Default values
'order' => 'ASC',
'orderby' => 'comment_date_gmt',
'status' => 'approve'
),
$args, // Any arguments passed to the function
array( // Merge meta-arguments last, so nothing can overwrite them
'meta_key' => 'custom_author_id',
'meta_value' => $author_id
)
);
// Perform the query and return the results
$comment_query = new WP_Comment_Query;
return $comment_query->query( $comment_args );
}
// Get the total number of comments with a custom_author_id meta-value of $author_id
function wpse202471_get_author_comment_count( $author_id = null, $args = array() ) {
$args[ 'count' ] = true;
// Remove query arguments that would prevent the proper count from being returned
if( isset( $args[ 'number' ] ) )
unset( $args[ 'number' ] );
if( isset( $args[ 'offset' ] ) )
unset( $args[ 'offset' ] );
return wpse202471_get_author_comments( $author_id, $args );
}

<p>Among WordPress' <a href="https://codex.wordpress.org/Roles_and_Capabilities" rel="noreferrer">capabilities</a> are <code>unfiltered_html</code> and <code>unfiltered_upload</code>, however I have yet to find any documentation about what specifically they allow or prevent in their filtering. </p>
<p>The only mention I've found on WordPress' site about <code>unfiltered_html</code> is:</p>
<blockquote>
<p>Allows user to post HTML markup or even JavaScript code in pages,
posts, comments and widgets.</p>
</blockquote>
<p>I've seen that JavaScript is filtered out for non-admins, but what HTML is being filtered? </p>
<p>And for <code>unfiltered_upload</code>:</p>
<blockquote>
<p>This capability is not available to any role by default (including
Super Admins). The capability needs to be enabled by defining the
following constant:</p>
<pre><code>define( 'ALLOW_UNFILTERED_UPLOADS', true );
</code></pre>
<p>With this constant defined, all roles on a single site install can be
given the unfiltered_upload capability, but only Super Admins can be
given the capability on a Multisite install.</p>
</blockquote>
<p>And again, the description doesn't spell out what's permitted and what's filtered out. </p>
<p>Can someone tell me exactly what elements, code, or file types the <code>unfiltered_html</code> and <code>unfiltered_upload</code> capabilities allow or prevent?</p>

Among WordPress' [capabilities](https://codex.wordpress.org/Roles_and_Capabilities) are `unfiltered_html` and `unfiltered_upload`, however I have yet to find any documentation about what specifically they allow or prevent in their filtering.
The only mention I've found on WordPress' site about `unfiltered_html` is:
>
> Allows user to post HTML markup or even JavaScript code in pages,
> posts, comments and widgets.
>
>
>
I've seen that JavaScript is filtered out for non-admins, but what HTML is being filtered?
And for `unfiltered_upload`:
>
> This capability is not available to any role by default (including
> Super Admins). The capability needs to be enabled by defining the
> following constant:
>
>
>
> ```
> define( 'ALLOW_UNFILTERED_UPLOADS', true );
>
> ```
>
> With this constant defined, all roles on a single site install can be
> given the unfiltered\_upload capability, but only Super Admins can be
> given the capability on a Multisite install.
>
>
>
And again, the description doesn't spell out what's permitted and what's filtered out.
Can someone tell me exactly what elements, code, or file types the `unfiltered_html` and `unfiltered_upload` capabilities allow or prevent?
|
It is hard to come up with *precise* answer since capabilities are often used more broadly than they imply. For example check for `manage_options` is usually synonym to check for admin user and can come up in contexts that don't actually have much to do with *options*.
*Usually* it will be a difference between subject content passing or not passing through [`wp_kses()`](https://codex.wordpress.org/Function_Reference/wp_kses). Specific kses settings and what is considered allowed would depend on the context and might wary.
For `unfiltered_upload` as far as I remember it's more straightforward. Without it only white listed file types are allowed. The list is based on [`wp_get_mime_types()`](https://codex.wordpress.org/Function_Reference/wp_get_mime_types).

<p>I have a simple table layout as per below:</p>

<p>And the following CSS:</p>
<pre><code>table td:nth-child(1),
table tr:nth-child(1) {

<p>The first column is bolded but the first row remains as normal text. I don't want to use headers as TinyMCE in Wordpress creates tables automatically in the above format so I'd rather just stick with that rather than then have to change the HTML.</p>
<p>Incidentally, the following does work so I assume there is no issue using "tr:nth-child(n)"</p>

After much frustration I realised that the issue is the fact that you need ultimately to specify what you do with the **cell** in the nth row, hence the correct code is:
```
table td:nth-child(1),
table tr:nth-child(1) td {
font-weight: bold;
}
```
Putting this up as the answer as there are a lot of sources that use the header to style the top row but don't stipulate what needs to be done if you have a table layout without a header.

so I have read the codex and also a lot of articles on the Web, but still I cant understand the reason why this sort of functionality doesn't exist in WordPress by default.
It exists only for posts -Function Reference/the excerpt.
Second question is what is the most elegant way to solve it ?
There are a few plugins or snippets of code that enable you to add html editor to the category description in the admin side, but selecting the read more link doesnt work there:(
Is the only solution to write a very long Hook/filter on the category\_description() function ?
to elaborate: this is my code in category.php , - what is does is diplaying the parent category and all its children(titles+ full descriptions)
```
<?php
$CategoryPar = get_category( get_query_var( 'cat' ) );
$cat_id = $CategoryPar->cat_ID;
$args = array(
'orderby' => 'name',
'child_of' => $cat_id,
'hide_empty' => FALSE,
'order' => 'ASC'
);
$Ecategories = get_categories($args);
echo'<div class="cat-sub-title">';
foreach($Ecategories as $Ecategory) {
echo '<p><a href="' . get_category_link( $Ecategory->term_id ) . '" title="' . sprintf( __( "View all posts in %s" ), $Ecategory->name ) . '" ' . '>' . $Ecategory->name.'</a> </p> ';
echo '<div class="cat-sub-title-desc">'. $Ecategory->description . '</div>';
}
echo'</div>';
?>
```

I've been looking for a filter for `category_description()` and I have not found any. You could use `wp_trim_words()` with `category_description()` to get the desired result. For example:
```
$cat_ID = 4;
// wp_trim_words( $text, $num_words = 55, $more = null );
echo wp_trim_words( category_description( $cat_ID ), 55, '<a href="' . get_category_link( $cat_ID ) . '">' . __("Read more", "text-domain" ) . '</a>' );
```
Update: I've found the filter
-----------------------------
```
add_filter( 'category_description', 'cyb_trim_category_desc', 10, 2 );
function cyb_trim_category_desc( $desc, $cat_id ) {
// wp_trim_words( $text, $num_words = 55, $more = null );
$desc = wp_trim_words( $desc, 55, '<a href="' . get_category_link( $cat_id ) . '">' . __("Read more", "text-domain" ) . '</a>' );
return $desc;
}
```
**Note**: if you use the generic `the_archive_description()` function in your theme, the above filter works perfectly for categories archvie.

disable the oembed like below in functions.php :

<p>I'm trying to output the values of two custom fields created by ACF plugin in a custom post type. I actually need this to be displayed in a popup window. wordpress popup plugins don't support php code, only shortcodes can be called from the content editor. So I'm trying to create a shortcode to be used in the editor of the popup to display the values of the custom fields.
I know that we can generate shortcode <code>[cite]</code> using this code in theme functions.php</p>

We've built shortcodes in the past using concatenating variables.
To paraphrase the link above, you should output your PHP as such.
```
$output = '<p>';
$output .= '<strong>' . $content . '</strong>';
$output .= '</p>';
return $output;
```
Note, see the `.=` variable concatenation.

<p>I have tried several options like setting <code>'container' => false</code> and registering the <strong>theme_location</strong> and searching on forums but I am unable to get rid of the "div" coming with the wp_nav_menu
in my page:</p>
<pre><code><?php get_nav_menu();?>
function get_nav_menu() {
$navMenuDefaults = array(
'theme_location' => 'header-nav',
'menu' => '',
'container' => false,
'container_class' => '',
'container_id' => '',
'menu_class' => '',
'menu_id' => '',
'echo' => true,
'fallback_cb' => 'wp_page_menu',
'before' => '',
'after' => '',
'link_before' => '',
'link_after' => '',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s</ul>',
'depth' => 0,
'walker' => ''
);
return wp_nav_menu($navMenuDefaults);
}
</code></pre>
<p>and in functions.php:</p>
<pre><code>function register_top_nav() {
register_nav_menu('header-nav',__( 'Header Nav' ));
}
add_action( 'init', 'register_top_nav' );
</code></pre>
<p>I am not sure why I am getting the following output:</p>
<pre><code><div class="">
<ul>
<li class="page_item page-item-2">
<a href="url">Sample Page</a>
</li>
</ul>
</div>
</code></pre>
<p>How can I get something like following:</p>
<pre><code><ul class="abc">
<li>
<a href="#">dfdf</a>
</li>
</ul>
</code></pre>
<p>thanks.</p>

How can I get something like following:

<a href="#">dfdf</a>
</li>
</ul>
```
thanks.

FYI :`container => ''` is a string operation and it's default set by `div` you can't use `true or false like bool expression`.
Just change the `container => 'ul'` then i hope you will get what you want to see.
for more details please read this : <https://developer.wordpress.org/reference/functions/wp_nav_menu/>
Thanks

<p>I'm using the <a href="http://civicrm.org" rel="nofollow">CiviCRM</a> plugin for WordPress, and in the plugin's main file, <code>civicrm.php</code>, it calls <code>add_action()</code> to add a function to <code>wp_head()</code> in order to merge CiviCRM's header with my theme's header:</p>
<pre><code>add_action( 'wp_head', array( $this, 'wp_head' ) );
</code></pre>
<p>The actual function within civicrm.php is found below:</p>
<pre><code>public function wp_head() {

// CRM-11823 - If Civi bootstrapped, then merge its HTML header with the CMS's header
global $civicrm_root;

$region = CRM_Core_Region::instance('html-header', FALSE);

<p>I have confirmed that the code gets called when I switch to the twentyfifteen theme, but on my custom theme (which is based on an old version of <a href="http://roots.io" rel="nofollow">Roots</a>), this code does not get called. I have also confirmed that my custom theme is actually calling the main WordPress <code>wp_head()</code> function.</p>
<p>Any ideas on what could be going wrong in my custom theme that would cause this custom <code>wp_head</code> hook to not get called or otherwise error out in some way?</p>

I'm using the [CiviCRM](http://civicrm.org) plugin for WordPress, and in the plugin's main file, `civicrm.php`, it calls `add_action()` to add a function to `wp_head()` in order to merge CiviCRM's header with my theme's header:
```
add_action( 'wp_head', array( $this, 'wp_head' ) );
```
The actual function within civicrm.php is found below:
```
public function wp_head() {
echo "calling wp_head"; //added by me to test if the code gets called
// CRM-11823 - If Civi bootstrapped, then merge its HTML header with the CMS's header
global $civicrm_root;
if ( empty( $civicrm_root ) ) {
return;
}
$region = CRM_Core_Region::instance('html-header', FALSE);
if ( $region ) {
echo '<!-- CiviCRM html header -->';
echo $region->render( '' );
}
}
```
I have confirmed that the code gets called when I switch to the twentyfifteen theme, but on my custom theme (which is based on an old version of [Roots](http://roots.io)), this code does not get called.

I figured out the issue:
When CiviCRM was applying the template in `civicrm.basepage.php`, `$page_template` was coming back as `page.php`, but my base template was actually named `base.php`.
I added the following code in my theme's initialization and it resolved the issue:
```
add_filter( 'civicrm_basepage_template', 'psca_civicrm_basepage_template' );
function psca_civicrm_basepage_template( $template ) {
return 'base.php';
}

$output.=' </div>
</div>
</div>
</div>';
```
A standard if else would have worked OK too so I'm not sure where the confusion was.
Another way is to use a php output buffer which would work like this:
```
ob_start();
?>
<div class="w-blog-entry" style="padding:0;"> etc etc
<?php if(get_post_meta( get_the_ID(), 'campus', true )) {?>
<p>True paragraph</p>
<?php }else{ ?>
<p>false paragraph</p>
<?php } ?>
```
And then when you've finished with all your output you put it in your $output variable like this:
```
$output = ob_get_clean();
```
When you start an output buffer it basically means that any HTML you put outside of the PHP tags goes into the buffer rather than being output to the browser. I prefer this sometimes when there's a lot of different conditions and logic in the output.
[ob\_start](http://php.net/manual/en/function.ob-start.php), [ob\_get\_clean](http://php.net/manual/en/function.ob-get-clean.php)

The answer about necessity is firmly **yes**. Escaping output is the most basic security practice.

I have been searching for several hours to find a way to embed the "Add New Post" inside a page in the front end. I read [this post](https://wordpress.stackexchange.com/questions/128288/how-can-i-place-the-add-new-post-contents-on-a-custom-page) but sadly no answer to it.
I have embedded the login form in another page called (example.com/user-login) and What I want is to have a page (example.com/add-post) which allows the person who logged in to publish a post in a page that is within the WordPress theme.
The same way as default method of publishing a post (example.com/wp-admin/post-new.php) but without going to the wordpress dashboard.
I have found several plugins that allow **guest posts**, but I want to **person who logged in**, be able to post.

This is pretty simple. So simple you need to make sure your guests don't insert bad code into you DB. So read up on [Data Validation](https://codex.wordpress.org/Data_Validation) and [Validating Sanitizing and Escaping User Data](https://codex.wordpress.org/Validating_Sanitizing_and_Escaping_User_Data) before you add anything to your site from a front-end form.
1. Create a new page at `/new-post`
2. Create a page template to target that page
3. Setup AJAX actions
4. Render your form inside the custom page template.
5. Use jQuery to submit the form details to AJAX
6. AJAX action will validate the data
7. If good, the new post will be created
8. AJAX will output a success or fail response
9. jQuery on the front-end form will inform the user of success or failure.
First, create a page called `new-post` that will hold your form. Then create a [page template](https://developer.wordpress.org/themes/template-files-section/page-template-files/page-templates/#creating-a-custom-page-template-for-one-specific-page) to target that page using the file structure `page-{slug}.php`.
```
page-new-post.php
```
On that page you can check to see if [is\_user\_logged\_in](https://codex.wordpress.org/Function_Reference/is_user_logged_in) and if they have the ability to create posts using [current\_user\_can](https://codex.wordpress.org/Function_Reference/current_user_can). If not, you can always [wp\_redirect](https://codex.wordpress.org/Function_Reference/wp_redirect) elsewhere or just [wp\_die](https://codex.wordpress.org/Function_Reference/wp_die).
You'll need to do all this with [AJAX](https://codex.wordpress.org/AJAX_in_Plugins) so create a front-end form that when clicked; submits data to WP, validates, and creates a new post.
Take note of `_nopriv` which you don't want to use in your case because someone will SPAM your site to a crawl.
```
// AJAX for logged in users
add_action( 'wp_ajax_create_new_post', 'ajax_create_new_post_action' );
// AJAX for non-logged in users
add_action( 'wp_ajax_nopriv_create_new_post', 'ajax_nopriv_create_new_post_action' );
```
Once you've collected the data and sanitized it in your `ajax_create_new_post_action` then you'll need to create a new post with [wp\_insert\_post](https://codex.wordpress.org/Function_Reference/wp_insert_post).
---
Since there are quite a few steps involved I recommend generating most of this automatically using [WP Secure Forms](http://chrisplaneta.com/generators/wpsecureforms/) and filling in the gaps after. Here is an example of an AJAX email submission form to give you a pretty good overview of the AJAX parts -- including sanitization.
Template for [WP Secure Forms](http://chrisplaneta.com/generators/wpsecureforms/)
---------------------------------------------------------------------------------
```
Title {30 characters limit}
> * 30
| Your Title
! Field specific error message
Textarea{150 characters limit}
> 150
| Content
|
|
! Field specific error message
This label is invisible
> H
```
Form
----
This script goes into the PHP file of your theme.
```
<p id="wpse_form_message_wrap" class="secureforms-message-wrap"></p>
<form id="wpse_form" method="post">
<div id="wpse_form_10000-wrapper">
<label for="wpse_form_10000">* Title <span>30 characters limit</span></label>
<input type="text" name="wpse_form_10000" id="wpse_form_10000" value="" placeholder="Your Title" required="required" maxlength="30" />
<p class="secureforms-error-msg">Field specific error message</p>
</div>
<div id="wpse_form_20000-wrapper">
<label for="wpse_form_20000">Textarea{150 characters limit}</label>
<textarea rows="3" name="wpse_form_20000" id="wpse_form_20000" value="" maxlength="150" ></textarea>
<p class="secureforms-error-msg">Field specific error message</p>
</div>
<div id="wpse_form_30000-wrapper" class="secureforms-hidden-wrapper">
<input id="wpse_form_30000" name="wpse_form_30000" type="hidden">
</div>
<div id="wpse_form_footer">
<input type="hidden" id="check_wpse_form" name="check_wpse_form" value="" />
<input type="hidden" name="action" value="wpse_form" />
<?php echo wp_nonce_field('wpse_form', '_nonce_eklwu', true, false); ?>
<input type="submit" name="wpse_form_submit_btn" id="wpse_form_submit_btn" value="Submit" />
</div>
</form>
```
Functions.php
-------------
This one goes into your functions.php
```
// WP SECURE FORMS - EMAIL VALIDATION & SENDING
require_once( 'ajax/wpse_form.php' );
// WP SECURE FORMS - ENQUEUE EMAIL JS
function enqueue_ajax_wpse_form() {
if (!is_admin()) {
wp_enqueue_script( 'ajax_wpse_form', get_template_directory_uri().'/ajax/wpse_form.js', array('jquery'), '', true );
wp_localize_script( 'ajax_wpse_form', 'ajax_wpse_form', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
}
add_action( 'wp_enqueue_scripts', 'enqueue_ajax_wpse_form', 999 );
```
Validation
----------
In your theme folder create an "ajax" folder with the file named wpse\_form.php. Paste into it the code below.
```
<?php
function ajax_wpse_form_action() {
if ($_SERVER["REQUEST_METHOD"] == "POST"){
$return_message = '';
$status = 'success';
$fields_with_errors = array();
// validate nonce
if(!wp_verify_nonce($_POST['_nonce_eklwu'], $_POST['action'])){
$status = 'error';
}
// validate hidden field
if(!empty(trim($_POST['check_wpse_form']))){
$status = 'error';
}
if ($status == 'error') {
$return_message = 'Data verification error. Check marked fields.';
} else {
$wpse_form_10000 = strip_tags(trim(stripslashes($_POST['wpse_form_10000'])));
if(!empty($wpse_form_10000)){
if(strlen($wpse_form_10000) > 30){
$status = 'error';
$fields_with_errors[] = 'wpse_form_10000';
}
} else {
$status = 'error';
$fields_with_errors[] = 'wpse_form_10000';
}
$wpse_form_20000 = strip_tags(trim(stripslashes($_POST['wpse_form_20000'])));
if(!empty($wpse_form_20000)){
if(strlen($wpse_form_20000) > 150){
$status = 'error';
$fields_with_errors[] = 'wpse_form_20000';
}
}
$wpse_form_30000 = strip_tags(trim(stripslashes($_POST['wpse_form_30000'])));
if ($status == 'error') {
$return_message = 'Data verification error. Check marked fields.';
} else {
// message
$to = '[email protected]';
$header = 'From: '. get_bloginfo('name') . ' <[email protected]>'.PHP_EOL;
$subject = 'Test Email Subject';
$formMessage = '';
$formMessage .= 'Title {30 characters limit}' . "\n";
$formMessage .= $wpse_form_10000 . "\n\n";
$formMessage .= 'Textarea{150 characters limit}' . "\n";
$formMessage .= $wpse_form_20000 . "\n\n";
$formMessage .= 'This label is invisible' . "\n";
$formMessage .= $wpse_form_30000 . "\n\n";
if ( wp_mail($to, $subject, $formMessage, $header) ) {
$return_message = 'Thank you for contacting us. We will get in touch as soon as possible.';
} else {
$status = 'error';
$return_message = 'There was an error sending the message. Please try again.';
}
}
}
$resp = array(
'status' => $status,
'return_message' => $return_message,
'fields_with_errors' => $fields_with_errors,
);
header( "Content-Type: application/json" );
echo json_encode($resp);
die();
} else {
http_response_code(403);
}
}
add_action( 'wp_ajax_wpse_form', 'ajax_wpse_form_action' );
add_action( 'wp_ajax_nopriv_wpse_form', 'ajax_wpse_form_action' );
```
AJAX
----
In your theme folder create an "ajax" folder with the file named wpse\_form.js. Paste into it this code.

<p>I've enqueued a .js file on the "Media Library" page (upload.php). I need to hide and manipulate a few of the thumbnails on the page using JS only ( I'm not looking for workarounds ). </p>
<p>The elements on the page are being rendered by backbone and I have found no way so far to hook into it. In any window/document state, $('li.attachment').hide() function for example won't do it's job because of this.</p>
<p>I have tried going with the following piece of code, with no result so far, can't even debug the code because of unproperly hooking:</p>
<pre><code>window.wp = window.wp || {};
( function( $, _ ) {
var media = wp.media,
Attachments = media.model.Attachments,
Query = media.model.Query,
original = {};
original.AttachmentsBrowser = {
manipulate: media.view.AttachmentsBrowser.prototype.manipulate
};
_.extend( media.view.AttachmentsBrowser.prototype, {
initialize: function() {
original.AttachmentsBrowser.initialize.apply( this, arguments );
},
manipulate: function() {
var options = this.options,
self = this,
i = 1;
original.AttachmentsBrowser.manipulate.apply( this, arguments );
console.log('got here'); // Not outputting a thing
}
});
</code></pre>
<p>Any ideas how I should go about it? </p>
<p>Thanks a lot in advance!</p>

I've enqueued a .js file on the "Media Library" page (upload.php). I need to hide and manipulate a few of the thumbnails on the page using JS only ( I'm not looking for workarounds ).
The elements on the page are being rendered by backbone and I have found no way so far to hook into it. In any window/document state, $('li.attachment').hide() function for example won't do it's job because of this.
I have tried going with the following piece of code, with no result so far, can't even debug the code because of unproperly hooking:
```
window.wp = window.wp || {};
( function( $, _ ) {
var media = wp.media,
Attachments = media.model.Attachments,
Query = media.model.Query,
original = {};
original.AttachmentsBrowser = {
manipulate: media.view.AttachmentsBrowser.prototype.manipulate
};
_.extend( media.view.AttachmentsBrowser.prototype, {
initialize: function() {
original.AttachmentsBrowser.initialize.apply( this, arguments );
},
manipulate: function() {
var options = this.options,
self = this,
i = 1;
original.AttachmentsBrowser.manipulate.apply( this, arguments );
console.log('got here'); // Not outputting a thing
}
});
```
Any ideas how I should go about it?
Thanks a lot in advance!

This is pretty simple. So simple you need to make sure your guests don't insert bad code into you DB. So read up on [Data Validation](https://codex.wordpress.org/Data_Validation) and [Validating Sanitizing and Escaping User Data](https://codex.wordpress.org/Validating_Sanitizing_and_Escaping_User_Data) before you add anything to your site from a front-end form.
1. Create a new page at `/new-post`
2. Create a page template to target that page
3. Setup AJAX actions
4. Render your form inside the custom page template.
5. Use jQuery to submit the form details to AJAX
6. AJAX action will validate the data
7. If good, the new post will be created
8. AJAX will output a success or fail response
9. jQuery on the front-end form will inform the user of success or failure.
First, create a page called `new-post` that will hold your form. Then create a [page template](https://developer.wordpress.org/themes/template-files-section/page-template-files/page-templates/#creating-a-custom-page-template-for-one-specific-page) to target that page using the file structure `page-{slug}.php`.
```
page-new-post.php
```
On that page you can check to see if [is\_user\_logged\_in](https://codex.wordpress.org/Function_Reference/is_user_logged_in) and if they have the ability to create posts using [current\_user\_can](https://codex.wordpress.org/Function_Reference/current_user_can). If not, you can always [wp\_redirect](https://codex.wordpress.org/Function_Reference/wp_redirect) elsewhere or just [wp\_die](https://codex.wordpress.org/Function_Reference/wp_die).
You'll need to do all this with [AJAX](https://codex.wordpress.org/AJAX_in_Plugins) so create a front-end form that when clicked; submits data to WP, validates, and creates a new post.
Take note of `_nopriv` which you don't want to use in your case because someone will SPAM your site to a crawl.
```
// AJAX for logged in users
add_action( 'wp_ajax_create_new_post', 'ajax_create_new_post_action' );
// AJAX for non-logged in users
add_action( 'wp_ajax_nopriv_create_new_post', 'ajax_nopriv_create_new_post_action' );
```
Once you've collected the data and sanitized it in your `ajax_create_new_post_action` then you'll need to create a new post with [wp\_insert\_post](https://codex.wordpress.org/Function_Reference/wp_insert_post).
---
Since there are quite a few steps involved I recommend generating most of this automatically using [WP Secure Forms](http://chrisplaneta.com/generators/wpsecureforms/) and filling in the gaps after. Here is an example of an AJAX email submission form to give you a pretty good overview of the AJAX parts -- including sanitization.
Template for [WP Secure Forms](http://chrisplaneta.com/generators/wpsecureforms/)
---------------------------------------------------------------------------------
```
Title {30 characters limit}
> * 30
| Your Title
! Field specific error message
Textarea{150 characters limit}
> 150
| Content
|
|
! Field specific error message
This label is invisible
> H
```
Form
----
This script goes into the PHP file of your theme.
```
<p id="wpse_form_message_wrap" class="secureforms-message-wrap"></p>
<form id="wpse_form" method="post">
<div id="wpse_form_10000-wrapper">
<label for="wpse_form_10000">* Title <span>30 characters limit</span></label>
<input type="text" name="wpse_form_10000" id="wpse_form_10000" value="" placeholder="Your Title" required="required" maxlength="30" />
<p class="secureforms-error-msg">Field specific error message</p>
</div>
<div id="wpse_form_20000-wrapper">
<label for="wpse_form_20000">Textarea{150 characters limit}</label>
<textarea rows="3" name="wpse_form_20000" id="wpse_form_20000" value="" maxlength="150" ></textarea>
<p class="secureforms-error-msg">Field specific error message</p>
</div>
<div id="wpse_form_30000-wrapper" class="secureforms-hidden-wrapper">
<input id="wpse_form_30000" name="wpse_form_30000" type="hidden">
</div>
<div id="wpse_form_footer">
<input type="hidden" id="check_wpse_form" name="check_wpse_form" value="" />
<input type="hidden" name="action" value="wpse_form" />
<?php echo wp_nonce_field('wpse_form', '_nonce_eklwu', true, false); ?>
<input type="submit" name="wpse_form_submit_btn" id="wpse_form_submit_btn" value="Submit" />
</div>
</form>
```
Functions.php
-------------
This one goes into your functions.php
```
// WP SECURE FORMS - EMAIL VALIDATION & SENDING
require_once( 'ajax/wpse_form.php' );
// WP SECURE FORMS - ENQUEUE EMAIL JS
function enqueue_ajax_wpse_form() {
if (!is_admin()) {
wp_enqueue_script( 'ajax_wpse_form', get_template_directory_uri().'/ajax/wpse_form.js', array('jquery'), '', true );
wp_localize_script( 'ajax_wpse_form', 'ajax_wpse_form', array( 'ajax_url' => admin_url( 'admin-ajax.php' ) ) );
}
}
add_action( 'wp_enqueue_scripts', 'enqueue_ajax_wpse_form', 999 );
```

<p>I am currently in the course of migrating site content from an old pre 4.1 site to a new setup and hitting an issue with the rounding error issue of <a href="https://core.trac.wordpress.org/ticket/18532" rel="noreferrer">#18532</a> and the <a href="https://core.trac.wordpress.org/changeset/30660" rel="noreferrer">corresponding fix</a>.</p>
<p>To summarize this fixed a long standing rounding misbehaviour on the side of WordPress:</p>
<p>Imagine we upload an image with 693x173 and scale it to a width of 300:</p>
<ul>
<li>pre 4.1: 300x74</li>
<li>post 4.1: 300x75</li>
</ul>
<h2>The issue</h2>
<p>Generally this doesn't cause any issues because existing files and <code><img></code> aren't touched.</p>
<p>But when you regenerating thumbs or importing attachments from a WXR file they get generated differently in the filesystem leaving all <code><img></code> in <code>post_content</code> dead.</p>
<h2>Looking for a solution</h2>
<p>I have been thinking of various solutions:</p>
<h3>Going back to the bad old times</h3>
<p><a href="https://core.trac.wordpress.org/changeset/30660" rel="noreferrer">Changeset 30660</a> introduced a new filter <code>wp_constrain_dimensions</code> which can be used to just plug the old behaviour from before 4.1 back in. This does fix the issue.
But I am wondering if this might cause issues later on and generally I'd like to have the fix so although this works I'd deem it non-ideal.</p>
<h3>The Times They Are a-Changin'</h3>
<p>So this leaves us with another goal: Clean up the DB and replace all references to the old files with references to the new files. The question I am actually asking here now is how to do this. I am looking for an effective and generally-applicable solution as I suspect this issue does and will affect a lot of people</p>
<p>My current idea is this:</p>
<ol>
<li>Import, regenerate or whatever which leaves us with the new files and broken tags.</li>
<li>Create a list A from all resized files in the filesystem or alternatively getting this information from the database</li>
<li>Parse this list and create a second list B with filenames all offset by one pixel as it would look before 4.1</li>
<li>Do a search&replace over the whole database replacing all occurences of B with the relating entry in A</li>
</ol>
<p>I am just not sure if this is the most smart and efficient way to handle this situation. It also feels a bit too brute-force. So before implementing it I just wanted to check with the infinite wisdom of the WPSE crowd ;)</p>
<p><em>[edit] Having read <a href="https://wordpress.stackexchange.com/users/35923/ck-macleod">ck-macleod</a>s answer (thanks!) I think a fix should solve this once and for all so you do not need to constantly keep this issue in the back of your head. [/edit]</em></p>
<p><em>[edit2] I just found a <a href="https://core.trac.wordpress.org/ticket/31581" rel="noreferrer">related ticket on Trac</a>. Adding for reference. [/edit2]</em></p>

I am currently in the course of migrating site content from an old pre 4.1 site to a new setup and hitting an issue with the rounding error issue of [#18532](https://core.trac.wordpress.org/ticket/18532) and the [corresponding fix](https://core.trac.wordpress.org/changeset/30660).
To summarize this fixed a long standing rounding misbehaviour on the side of WordPress:
Imagine we upload an image with 693x173 and scale it to a width of 300:
* pre 4.1: 300x74
* post 4.1: 300x75
The issue
---------
Generally this doesn't cause any issues because existing files and `<img>` aren't touched.
But when you regenerating thumbs or importing attachments from a WXR file they get generated differently in the filesystem leaving all `<img>` in `post_content` dead.
Looking for a solution
----------------------
I have been thinking of various solutions:
### Going back to the bad old times
[Changeset 30660](https://core.trac.wordpress.org/changeset/30660) introduced a new filter `wp_constrain_dimensions` which can be used to just plug the old behaviour from before 4.1 back in. This does fix the issue.
But I am wondering if this might cause issues later on and generally I'd like to have the fix so although this works I'd deem it non-ideal.
### The Times They Are a-Changin'
So this leaves us with another goal: Clean up the DB and replace all references to the old files with references to the new files. The question I am actually asking here now is how to do this. I am looking for an effective and generally-applicable solution as I suspect this issue does and will affect a lot of people
My current idea is this:
1. Import, regenerate or whatever which leaves us with the new files and broken tags.
2. Create a list A from all resized files in the filesystem or alternatively getting this information from the database
3. Parse this list and create a second list B with filenames all offset by one pixel as it would look before 4.1
4. Do a search&replace over the whole database replacing all occurences of B with the relating entry in A
I am just not sure if this is the most smart and efficient way to handle this situation. It also feels a bit too brute-force. So before implementing it I just wanted to check with the infinite wisdom of the WPSE crowd ;)
*[edit] Having read [ck-macleod](https://wordpress.stackexchange.com/users/35923/ck-macleod)s answer (thanks!) I think a fix should solve this once and for all so you do not need to constantly keep this issue in the back of your head. [/edit]*
*[edit2] I just found a [related ticket on Trac](https://core.trac.wordpress.org/ticket/31581). Adding for reference. [/edit2]*
|
This is another approach than [the other answer](https://wordpress.stackexchange.com/a/206986/47733) that works when importing content with the importer and fixes the URLs once and for all. Again: This is not battle-tested but is the solution I settled on and it did work.
I prefer this as it solves the issue once and for all and if it works, it works. As you are not leaving broken stuff in the DB and fix it on display you do not need to worry about stuff breaking later on.

I am trying to include bootstrap only when the short-code function executes. It gets included but it affects the other tags of the theme.
The only way I can get around this is including bootstrap globally in the plugin's primary file. It works on the front end, making the short-code execute and display output with bootstrap classes and all of the other page content is not affected by bootstrap.
But this way, these are included everywhere and this affects the back-end styles.
The problem is tied to both front and back ends. If one is fixed, the other gets broken.

I also find the typical practice of queuing globally or from inside shortcodes problematic.
I had a similar challenge with implementing code highlight on my site — I only wanted scripts and style to load as necessary. I ended up checking content for `<pre>` tag as condition to output:
```
{% if '<pre>' in get_the_content() %}
<link rel="stylesheet" href="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.4/styles/solarized_dark.min.css">
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.4/highlight.min.js"></script>
{% if has_term( 'twig', 'post_tag' ) %}
<script src="//cdnjs.cloudflare.com/ajax/libs/highlight.js/8.4/languages/twig.min.js"></script>
{% endif %}
<script type="text/javascript">
jQuery(document).ready(function ($) {
$('pre').each(function (i, e) {
hljs.highlightBlock(e)
});
});
</script>
{% endif %}
```
This is in Twig template (and doesn't use WP queue), but you can use same approach in PHP just as well.

I have split my post content into mutiple pages using the `<! - nextpage ->` code. I want to give my paginated links their own title instead of the regular 1,2,3. How can I do this? cause on this doc <https://codex.wordpress.org/Styling_Page-Links> it only mentions method to adding suffix or prefix. I just want to give each paged number their own custom title

Here's a way to support pagination titles of the form:
```
<!--nextpage(.*?)?-->
```
in a simlar way as the core supports `<!--more(.*?)?-->`.
Here's an example:
```
<!--nextpage Planets -->
Let's talk about the Planets
<!--nextpage Mercury -->
Exotic Mercury
<!--nextpage Venus-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
with the output similar to:
[](https://i.stack.imgur.com/lAGwM.jpg)
This was tested on the *Twenty Sixteen* theme, where I had to adjust the *padding* and *width* a little bit:
```
.page-links a, .page-links > span {
width: auto;
padding: 0 5px;
}
```
Demo plugin
-----------
Here's a demo plugin that uses the `content_pagination`, `wp_link_pages_link`, `pre_handle_404` and `wp_link_pages_args` filters to support this extenstion of the *nextpage* marker (*PHP 5.4+*):
```
<?php
/**
* Plugin Name: Content Pagination Titles
* Description: Support for <!--nextpage(.*?)?--> in the post content
* Version: 1.0.1
* Plugin URI: http://wordpress.stackexchange.com/a/227022/26350

add_action( 'init', function()

$main->init();
} );

{
add_filter( 'pre_handle_404', [ $this, 'pre_handle_404' ], 10, 2 );
add_filter( 'content_pagination', [ $this, 'content_pagination' ], -1, 2 );
add_filter( 'wp_link_pages_link', [ $this, 'wp_link_pages_link' ], 10, 2 );
add_filter( 'wp_link_pages_args', [ $this, 'wp_link_pages_args' ], PHP_INT_MAX );
}
public function content_pagination( $pages, $post )
{
// Empty content pagination titles for each run
$this->pagination_titles = [];
// Nothing to do if the post content doesn't contain pagination titles
if( false === stripos( $post->post_content, '<!--nextpage' ) )
return $pages;
// Collect pagination titles
preg_match_all( '/<!--nextpage(.*?)?-->/i', $post->post_content, $matches );
if( isset( $matches[1] ) )
$this->pagination_titles = $matches[1];
// Override $pages according to our new extended nextpage support
$pages = preg_split( '/<!--nextpage(.*?)?-->/i', $post->post_content );
// nextpage marker at the top
if( isset( $pages[0] ) && '' == trim( $pages[0] ) )
{
// remove the empty page
array_shift( $pages );
}
// nextpage marker not at the top
else
{
// add the first numeric pagination title
array_unshift( $this->pagination_titles, '1' );
}
return $pages;
}
public function wp_link_pages_link( $link, $i )
{
if( ! empty( $this->pagination_titles ) )
{
$from = '{{TITLE}}';
$to = ! empty( $this->pagination_titles[$i-1] ) ? $this->pagination_titles[$i-1] : $i;
$link = str_replace( $from, $to, $link );
}
return $link;
}
public function wp_link_pages_args( $params )
{
if( ! empty( $this->pagination_titles ) )
{
$params['next_or_number'] = 'number';
$params['pagelink'] = str_replace( '%', '{{TITLE}}', $params['pagelink'] );
}
return $params;
}
/**
* Based on the nextpage check in WP::handle_404()
*/
public function pre_handle_404( $bool, \WP_Query $q )
{
global $wp;
if( $q->posts && is_singular() )
{
if ( $q->post instanceof \WP_Post )
$p = clone $q->post;
// check for paged content that exceeds the max number of pages
$next = '<!--nextpage';
if ( $p
&& false !== stripos( $p->post_content, $next )
&& ! empty( $wp->query_vars['page'] )
) {
$page = trim( $wp->query_vars['page'], '/' );
$success = (int) $page <= ( substr_count( $p->post_content, $next ) + 1 );
if ( $success )
{
status_header( 200 );
$bool = true;
}
}
}
return $bool;
}
} // end class
```
*Installation*: Create the `/wp-content/plugins/content-pagination-titles/content-pagination-titles.php` file and activate the plugin. Always a good idea to backup before testing any plugin.
If the top *nextpage* marker is missing, then the first pagination title is numeric.
Also if a content pagination title is missing, i.e. `<!--nextpage-->`, then it will be numeric, just as expected.
I first forgot about the *nextpage* bug in the `WP` class, that shows up if we modify the number of pages via the `content_pagination` filter. This was recently reported by @PieterGoosen here in [#35562](https://core.trac.wordpress.org/ticket/35562).
We try to overcome that in our demo plugin with a `pre_handle_404` filter callback, based on the `WP` class check [here](https://github.com/WordPress/WordPress/blob/0016e4bb122a8da9b70d2703f805ba5a9821eadd/wp-includes/class-wp.php#L652-680), where we check for `<!--nextpage` instead of `<!--nextpage-->`.
Tests
-----
Here are some further tests:
**Test #1**
```
<!--nextpage-->
Let's talk about the Planets
<!--nextpage-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage-->
Our Blue Earth
<!--nextpage-->
The Red Planet
```
Output for *1* selected:
[](https://i.stack.imgur.com/9QbDd.jpg)
as expected.
**Test #2**
```
Let's talk about the Planets
<!--nextpage-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage-->
Our Blue Earth
<!--nextpage-->
The Red Planet
```
Output for *5* selected:
[](https://i.stack.imgur.com/rH9Yq.jpg)
as expected.
**Test #3**
```
<!--nextpage-->
Let's talk about the Planets
<!--nextpage Mercury-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
Output for *3* selected:
[](https://i.stack.imgur.com/k6CTp.jpg)
as expected.
**Test #4**
```
Let's talk about the Planets
<!--nextpage Mercury-->
Exotic Mercury
<!--nextpage Venus-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
Output with *Earth* selected:
[](https://i.stack.imgur.com/aZDHs.jpg)
as expected.
Alternatives
------------
Another way would be to modify it to support pagination titles to be added with:
```
<!--pt Earth-->
```
It might also be handy to support a single comment for all pagination titles (*pts*):
```
<!--pts Planets|Mercury|Venus|Earth|Mars -->
```
or perhaps via custom fields?

I cannot get it to work, however, and I am not sure what I am doing wrong. Is it not allowed to use JavaScript in this way? If not, what is the proper way to do it?</p>
<p>Running the below snippet does nothing when hitting the submit button.</p>
<pre><code>echo "
<script type=\"text/javascript\">
function validateForm()
{
alert(\"FOOO\");
return false;
}
</script>
<h1>Header</h1><br>
<form method=\"post\" onsubmit=\"validateForm()\">
<input type=\"submit\" value=\"Submit me\" /><br>
</form>
";
</code></pre>
<p><strong>Update:</strong></p>
<p>Here is the entire plugin, stripped down to just a small test. The JavaScript console shows nothing except a jQuery warning: <em>JQMIGRATE: jQuery.fn.live() is deprecated</em>. I am not sure where this originates from, but I do not use jQuery directly.</p>
<p>When I activate the plugin and click the button, the page is reloaded with the button and all, but the message <em>Yes, it was posted!</em> is not displayed. Thus it seems that no POST request is made. Removing the script and the <code>onsubmit</code> from the PHP <code>echo</code> produces the same behavior.</p>
<pre><code><?php
/*
Plugin Name: Test Plugin
*/
// Create plugin menu.
add_action('admin_menu', 'create_test_plugin_menu');
function create_test_plugin_menu()
{
add_menu_page('The Test Plugin', 'Test Plugin', 'administrator', __FILE__, 'setup_test_plugin');
}
function setup_test_plugin()
{
$submit_name = 'test_button';
if ( $_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST[$submit_name]) )
{
echo "Yes, it was posted!";
}

I have created a small custom plugin which is just an HTML form. The HTML form is `echo`'d out using PHP and it includes a small JavaScript function that I want to run on submission. I cannot get it to work, however, and I am not sure what I am doing wrong. Is it not allowed to use JavaScript in this way? If not, what is the proper way to do it?
Running the below snippet does nothing when hitting the submit button.
```
echo "
<script type=\"text/javascript\">
function validateForm()
{
alert(\"FOOO\");
return false;
}
</script>
<h1>Header</h1><br>
<form method=\"post\" onsubmit=\"validateForm()\">
<input type=\"submit\" value=\"Submit me\" /><br>
</form>
";
```
**Update:**
Here is the entire plugin, stripped down to just a small test. The JavaScript console shows nothing except a jQuery warning: *JQMIGRATE: jQuery.fn.live() is deprecated*. I am not sure where this originates from, but I do not use jQuery directly.
When I activate the plugin and click the button, the page is reloaded with the button and all, but the message *Yes, it was posted!* is not displayed. Thus it seems that no POST request is made. Removing the script and the `onsubmit` from the PHP `echo` produces the same behavior.
```
<?php
/*
Plugin Name: Test Plugin
*/
// Create plugin menu.
add_action('admin_menu', 'create_test_plugin_menu');
function create_test_plugin_menu()
{
add_menu_page('The Test Plugin', 'Test Plugin', 'administrator', __FILE__, 'setup_test_plugin');
}
function setup_test_plugin()
{
$submit_name = 'test_button';
if ( $_SERVER["REQUEST_METHOD"] == "POST" && isset($_POST[$submit_name]) )
{
echo "Yes, it was posted!";
}
else
{
echo "
<script type=\"text/javascript\">
function validateForm()
{
alert(\"FOOO\");
return false;
}
</script>
<h1>Header</h1><br>
<form method=\"post\" onsubmit=\"validateForm()\">
<input type=\"submit\" name=\"{$submit_name}\" value=\"Submit me\" /><br>
</form>
";
}
}
?>
```
Here is what is printed to the HTML source, copied from the JavaScript console.
```
<script type="text/javascript">
function validateForm()
{
alert("FOOO");
return false;
}
</script>
<h1>Header</h1><br>
<form method="post" onsubmit="validateForm()">
<input type="submit" name="test_button" value="Submit me" /><br>
</form>

Here's a way to support pagination titles of the form:
```
<!--nextpage(.*?)?-->
```
in a simlar way as the core supports `<!--more(.*?)?-->`.
Here's an example:
```
<!--nextpage Planets -->
Let's talk about the Planets
<!--nextpage Mercury -->
Exotic Mercury
<!--nextpage Venus-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
with the output similar to:
[](https://i.stack.imgur.com/lAGwM.jpg)
This was tested on the *Twenty Sixteen* theme, where I had to adjust the *padding* and *width* a little bit:
```
.page-links a, .page-links > span {
width: auto;
padding: 0 5px;
}
```
Demo plugin
-----------
Here's a demo plugin that uses the `content_pagination`, `wp_link_pages_link`, `pre_handle_404` and `wp_link_pages_args` filters to support this extenstion of the *nextpage* marker (*PHP 5.4+*):
```
<?php
/**
* Plugin Name: Content Pagination Titles
* Description: Support for <!--nextpage(.*?)?--> in the post content
* Version: 1.0.1
* Plugin URI: http://wordpress.stackexchange.com/a/227022/26350
*/
namespace WPSE\Question202709;
add_action( 'init', function()
{
$main = new Main;
$main->init();
} );
class Main
{
private $pagination_titles;
public function init()
{
add_filter( 'pre_handle_404', [ $this, 'pre_handle_404' ], 10, 2 );
add_filter( 'content_pagination', [ $this, 'content_pagination' ], -1, 2 );
add_filter( 'wp_link_pages_link', [ $this, 'wp_link_pages_link' ], 10, 2 );
add_filter( 'wp_link_pages_args', [ $this, 'wp_link_pages_args' ], PHP_INT_MAX );
}
public function content_pagination( $pages, $post )
{
// Empty content pagination titles for each run
$this->pagination_titles = [];
// Nothing to do if the post content doesn't contain pagination titles
if( false === stripos( $post->post_content, '<!--nextpage' ) )
return $pages;
// Collect pagination titles
preg_match_all( '/<!--nextpage(.*?)?-->/i', $post->post_content, $matches );
if( isset( $matches[1] ) )
$this->pagination_titles = $matches[1];
// Override $pages according to our new extended nextpage support
$pages = preg_split( '/<!--nextpage(.*?)?-->/i', $post->post_content );
// nextpage marker at the top
if( isset( $pages[0] ) && '' == trim( $pages[0] ) )
{
// remove the empty page
array_shift( $pages );
}
// nextpage marker not at the top
else
{
// add the first numeric pagination title
array_unshift( $this->pagination_titles, '1' );
}
return $pages;
}
public function wp_link_pages_link( $link, $i )
{
if( ! empty( $this->pagination_titles ) )
{
$from = '{{TITLE}}';
$to = ! empty( $this->pagination_titles[$i-1] ) ? $this->pagination_titles[$i-1] : $i;
$link = str_replace( $from, $to, $link );
}
return $link;
}
public function wp_link_pages_args( $params )
{
if( ! empty( $this->pagination_titles ) )
{
$params['next_or_number'] = 'number';
$params['pagelink'] = str_replace( '%', '{{TITLE}}', $params['pagelink'] );
}
return $params;
}
/**
* Based on the nextpage check in WP::handle_404()
*/
public function pre_handle_404( $bool, \WP_Query $q )
{
global $wp;
if( $q->posts && is_singular() )
{
if ( $q->post instanceof \WP_Post )
$p = clone $q->post;
// check for paged content that exceeds the max number of pages
$next = '<!--nextpage';
if ( $p
&& false !== stripos( $p->post_content, $next )
&& ! empty( $wp->query_vars['page'] )
) {
$page = trim( $wp->query_vars['page'], '/' );
$success = (int) $page <= ( substr_count( $p->post_content, $next ) + 1 );
if ( $success )
{
status_header( 200 );
$bool = true;
}
}
}
return $bool;
}
} // end class
```
*Installation*: Create the `/wp-content/plugins/content-pagination-titles/content-pagination-titles.php` file and activate the plugin. Always a good idea to backup before testing any plugin.
If the top *nextpage* marker is missing, then the first pagination title is numeric.
Also if a content pagination title is missing, i.e. `<!--nextpage-->`, then it will be numeric, just as expected.
I first forgot about the *nextpage* bug in the `WP` class, that shows up if we modify the number of pages via the `content_pagination` filter. This was recently reported by @PieterGoosen here in [#35562](https://core.trac.wordpress.org/ticket/35562).
We try to overcome that in our demo plugin with a `pre_handle_404` filter callback, based on the `WP` class check [here](https://github.com/WordPress/WordPress/blob/0016e4bb122a8da9b70d2703f805ba5a9821eadd/wp-includes/class-wp.php#L652-680), where we check for `<!--nextpage` instead of `<!--nextpage-->`.
Tests
-----
Here are some further tests:
**Test #1**
```
<!--nextpage-->
Let's talk about the Planets
<!--nextpage-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage-->
Our Blue Earth
<!--nextpage-->
The Red Planet
```
Output for *1* selected:
[](https://i.stack.imgur.com/9QbDd.jpg)
as expected.
**Test #2**
```
Let's talk about the Planets
<!--nextpage-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage-->
Our Blue Earth
<!--nextpage-->
The Red Planet
```
Output for *5* selected:
[](https://i.stack.imgur.com/rH9Yq.jpg)
as expected.
**Test #3**
```
<!--nextpage-->
Let's talk about the Planets
<!--nextpage Mercury-->
Exotic Mercury
<!--nextpage-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
Output for *3* selected:
[](https://i.stack.imgur.com/k6CTp.jpg)
as expected.
**Test #4**
```
Let's talk about the Planets
<!--nextpage Mercury-->
Exotic Mercury
<!--nextpage Venus-->
Beautiful Venus
<!--nextpage Earth -->
Our Blue Earth
<!--nextpage Mars -->
The Red Planet
```
Output with *Earth* selected:
[](https://i.stack.imgur.com/aZDHs.jpg)
as expected.
Alternatives
------------
Another way would be to modify it to support pagination titles to be added with:
```
<!--pt Earth-->
```
It might also be handy to support a single comment for all pagination titles (*pts*):
```
<!--pts Planets|Mercury|Venus|Earth|Mars -->
```
or perhaps via custom fields?

<p>But post-thumbnails default position is Under Publish tab.</p>
<p>Its look ugly, I want to show feature image Under title fields.
Where editor show, i want to show my feature image on that position.</p>
<p>Kindly tell me how this possible?</p>

<p><strong>IN case of not possible:</strong></p>
<p>If this not possible then tell me please:
when first time we open any post_type page, wordpress show 2 columns,
left side show title,editor,comments
or right side showing publish/thumbnail/category, etc</p>
<p>Is there any option to show default one column?
so all thing show in one side..</p>

register_post_type( 'slider', $args );
```
**IN case of not possible:**
If this not possible then tell me please:
when first time we open any post\_type page, wordpress show 2 columns,
left side show title,editor,comments
or right side showing publish/thumbnail/category, etc
Is there any option to show default one column?
so all thing show in one side..

Super late to the party, but well...
If you want to show your featured image right under the Post title in your Admin area, use this piece of code in your functions.php :
```
add_action('do_meta_boxes', 'my_cpt_move_meta_box');
function my_cpt_move_meta_box(){
remove_meta_box( 'postimagediv', 'post_type', 'side' );
add_meta_box('postimagediv', __('custom name'), 'post_thumbnail_meta_box', 'post_type', 'normal', 'high');
}
```
Be sure to change `post_type` to you rcustom post type slug. Additionally, you can add a custom name for th eimage (instead of 'Featured Image')

<p>I have a woocommerce setup for virtual products. All products are around 10MB and uploaded fine. I do however keep getting the following error show up when browsing the store:</p>
<pre><code>Trying to upload files larger than 128G is not allowed!
</code></pre>
<p>As you can see the file upload limit is 128GB and I have not tried uploading anything near the size of this. it was 128MB but i upped it to 128GB to try and get rid of the error.</p>
<p>Is there any reason why this could be happening?</p>
<p>Thanks

'order' => 'ASC',
'number' => $no,

Now what I want to do is to get all users that has only posts, i have an example query that i want to do. how do i do this with `wp_query()`?
```
SELECT users.id, posts.id
FROM wp_users
RIGHT JOIN wp_posts
ON wp_users.id = wp_posts.user_id
WHERE wp_posts.post_type = 'downloads'
AND wp_users.role = 'frontend_vendor'
ORDER BY display_name
ASC
LIMT 8
OFFEST 0
```
If the user has no posts, he should not be selected.

add this in your arguments `'query_id' => 'authors_with_posts',`
```
$user_args = array(
'role' => 'frontend_vendor',
'orderby' => 'display_name',
'query_id' => 'authors_with_posts',
'order' => 'ASC',
'number' => $no,

<p>Searching the code for related posts I found two almost identical code snippets, the only difference being that one uses echo: </p>
<pre><code>echo '<li><a href="' . get_permalink() . '" title="' . the_title_attribute() . '">' . the_title() . '</a></li>';
</code></pre>
<p>and the other does not:</p>
<pre><code><li>
<a href="<?php the_permalink() ?>" title="<?php the_title_attribute() ?>"> <h4><?php the_title() ?></h4></a>
</li>
</code></pre>
<p>Personally, I understand the second version (which mixes html with php) better, but I suspect, WP being what it is (always preferring php over html), that the first version may be the official way of doing things.</p>
<p>Is there are any preferred way of doing things in this case? And if yes why?</p>

The main differences are: the first snippet has *html inside php* while the second one has *php inside html*. Both approaches are basically valid, both are fine.

<p>I've created two new Custom Post types using code that I've used successfully on other projects without issue. The first is called <code>top_charts</code>, the other <code>case_studies</code>, and both appear correctly in the admin menu and I can create new posts.</p>
<p>Unfortunately the new posts don't appear. I just get a <code>404.php</code> response.</p>
<p>I've created an <code>archive-top_charts.php</code> to see if I can get anything to appear, but I see a <code>404.php</code> "page not found" reply.</p>
<p>I originally named the custom posts <code>top-charts</code> and <code>case-studies</code>, but I thought the hyphen might have been the problem, and so renamed them to use an underscore instead. It hasn't helped.</p>
<p>I've tried re-saving my Permalinks, but nothing has changed. My .htaccess page looks like what you'd expect, too (and other pages works fine). What else can I check?</p>

I've created two new Custom Post types using code that I've used successfully on other projects without issue. The first is called `top_charts`, the other `case_studies`, and both appear correctly in the admin menu and I can create new posts.
Unfortunately the new posts don't appear. I just get a `404.php` response.
I've created an `archive-top_charts.php` to see if I can get anything to appear, but I see a `404.php` "page not found" reply.
I originally named the custom posts `top-charts` and `case-studies`, but I thought the hyphen might have been the problem, and so renamed them to use an underscore instead. It hasn't helped.
I've tried re-saving my Permalinks, but nothing has changed. My .htaccess page looks like what you'd expect, too (and other pages works fine). What else can I check?
|
For fixing custom post not found please use below code in your `functions.php`:
```
flush_rewrite_rules( false );
```
You should only do this as a temporary measure otherwise it will run on every page load.
For more details please follow [this link](https://web.archive.org/web/20140403185155/https://nooshu.com/page-not-found-with-custom-post-types)
As for the `archive-top_charts.php` not appearing, make sure you have `'has_archive' => true` when you're registering your post type.

<p>I'm currently writing a script that is running on a server and is supposed to get information about
a) the WordPress version
b) the plugins
c) the plugin versions.</p>
<p>The WordPress version number is no problem, but I'm not sure how to reliably obtain the required plugin information. I've located the plugin folder (wp-content/plugins). Does this folder contain all plugins?</p>
<p>Even if it does, I don't know if there is a fixed structure to get
a) the official name
b) the official version number
of all plugins. </p>
<p>For example, one plugin I checked had the version number in a .php file with an @version annotation, but the version of the second plugin I checked was just part of the comments (Version = 2.66 or something like this).</p>
<p>Is there a reliable way to obtain this information without using PHP (because the script I'm writing is not limited to WordPress and must run on servers without PHP)? Something like a common structure, or a central file with collected information on the plugins? </p>

I have a site that needs to migrate from WP E-Commerce to WooCommerce.
I'm trying to use `WP All Import Pro` + `WP All Import Woocommerce add on` to do this.
I exported the WP E-Commerce products in an XML file, and imported the XML file into WooCommerce products using WP All Import.
It works fine, except I can't get the image URL from the XML file, there is only a thumbnail ID, which can't be used by the WP All Import Woocommerce add on (that I can see).
So, **I'd love to be able to convert a list of thumbnail IDs into their image URL equivalents**, and then swap these these URLs into the thumbnail ID field in the XML file.
How do I do this? Help appreciated.
|
There are two functions you can use for this: `wp_get_attachment_url` to get the full sized image or `wp_get_attachment_thumb_url`, which gets the url of the thumbnail of that attachment. Either function takes the attachment id as the sole argument:
```
$attachment_id= 25;
//Get the full url
$url = wp_get_attachment_url( $attachment_id );
//get the thumbnail
$thumb = wp_get_attachment_thumb_url( $attachment_id );
```
Not sure how to get this done in your XML file, though, so this is a partial answer, but hopefully it sends you in the right direction.

<pre><code> $product = get_product($product_id);
$order = wc_create_order();
$order->add_product( $product , 1 );
$order->calculate_totals();
// assign the order to the current user
update_post_meta($order->id, '_customer_user', get_current_user_id() );
// payment_complete
$order->payment_complete();
</code></pre>
<p>but when i use it for subscription product it does not add the subscription, it only add the order.</p>

I want to create a new order programatically.
This code works well with simple product,
```
$product = get_product($product_id);
$order = wc_create_order();
$order->add_product( $product , 1 );
$order->calculate_totals();
// assign the order to the current user
update_post_meta($order->id, '_customer_user', get_current_user_id() );
// payment_complete
$order->payment_complete();
```
but when i use it for subscription product it does not add the subscription, it only add the order.

Here's my code for creating a subscription -- it took a lot of trial and error to figure it all out. Best of luck!
```
function create_test_sub() {
$email = '[email protected]';
$start_date = '2015-01-01 00:00:00';
$address = array(
'first_name' => 'Jeremy',
'last_name' => 'Test',
'company' => '',
'email' => $email,
'phone' => '777-777-777-777',
'address_1' => '31 Main Street',
'address_2' => '',
'city' => 'Auckland',
'state' => 'AKL',
'postcode' => '12345',
'country' => 'AU'
);
$default_password = wp_generate_password();
if (!$user = get_user_by('login', $email)) $user = wp_create_user( $email, $default_password, $email );
// I've used one product with multiple variations
$parent_product = wc_get_product(22998);
$args = array(
'attribute_billing-period' => 'Yearly',
'attribute_subscription-type' => 'Both'
);
$product_variation = $parent_product->get_matching_variation($args);
$product = wc_get_product($product_variation);
// Each variation also has its own shipping class
$shipping_class = get_term_by('slug', $product->get_shipping_class(), 'product_shipping_class');
WC()->shipping->load_shipping_methods();
$shipping_methods = WC()->shipping->get_shipping_methods();
// I have some logic for selecting which shipping method to use; your use case will likely be different, so figure out the method you need and store it in $selected_shipping_method
$selected_shipping_method = $shipping_methods['free_shipping'];
$class_cost = $selected_shipping_method->get_option('class_cost_' . $shipping_class->term_id);
$quantity = 1;
// As far as I can see, you need to create the order first, then the sub
$order = wc_create_order(array('customer_id' => $user->id));
$order->add_product( $product, $quantity, $args);
$order->set_address( $address, 'billing' );
$order->set_address( $address, 'shipping' );
$order->add_shipping((object)array (
'id' => $selected_shipping_method->id,
'label' => $selected_shipping_method->title,
'cost' => (float)$class_cost,
'taxes' => array(),
'calc_tax' => 'per_order'
));
$order->calculate_totals();
$order->update_status("completed", 'Imported order', TRUE);
// Order created, now create sub attached to it -- optional if you're not creating a subscription, obvs
// Each variation has a different subscription period
$period = WC_Subscriptions_Product::get_period( $product );
$interval = WC_Subscriptions_Product::get_interval( $product );
$sub = wcs_create_subscription(array('order_id' => $order->id, 'billing_period' => $period, 'billing_interval' => $interval, 'start_date' => $start_date));
$sub->add_product( $product, $quantity, $args);
$sub->set_address( $address, 'billing' );
$sub->set_address( $address, 'shipping' );
$sub->add_shipping((object)array (
'id' => $selected_shipping_method->id,
'label' => $selected_shipping_method->title,
'cost' => (float)$class_cost,
'taxes' => array(),
'calc_tax' => 'per_order'
));
$sub->calculate_totals();
WC_Subscriptions_Manager::activate_subscriptions_for_order($order);
print "<a href='/wp-admin/post.php?post=" . $sub->id . "&action=edit'>Sub created! Click here to edit</a>";
}

<p>I have created the following action:</p>

<p>This works exactly the same in development on my Windows PC (running WAMP) than it is on Production (running Linux in AWS). Also, if I schedule the single event 5 minutes in the future (time() + 300) it shows in my "Debug Bar Cron" plugin as being available to run in 5 minutes time and it appears to run just fine. So it appears that the CRON jobs are being created but for some reason they are not actually calling the action when running? Has anyone else had this problem or have an insight into it?</p>

Because you're *scheduling* the event - even though it's set to run immediately (i.e. with `time()`), it won't fire until a second request.
So that log output is entirely expected. Try running it again, removing the code, then run once more - you should get:
```
[time] test_action
```

<p>I'm trying to hook up some JS so that when the featured image upload box is opened and an image selected I can use Vibrant.js to analyse the colours of the selected image. The hurdle I've encountered is that I can't find any particular event to bind my function to. I've looked at various tutorials regarding the <code>wp.media()</code> object, but they all seem to involve replacing the upload box completely. Is there no straightforward way of detecting when the featured image upload window is open and the selected thumbnail preview image is loaded?</p>

After some digging I discovered that wp.media.featuredImage.frame() was what I was looking for:
```
wp.media.featuredImage.frame().on('open',function() {
// Clever JS here
});
```
I then discovered that the `select` event fires once you've clicked on the 'Set featured image' button, *not* when you've clicked on thumbnail, which was what I was after. So I bound my events to the modal window itself once it was opened:
```
wp.media.featuredImage.frame().on('open', function() {
// Get the actual modal
var modal = $(wp.media.featuredImage.frame().modal.el);
// Do stuff when clicking on a thumbnail in the modal
modal.on('click', '.attachment', function() {
// Stuff and thangs
})
// Trigger the click event on any thumbnails selected previously
.find('attachment.selected').trigger('click');
});
```
The end result was that once the featured image modal was opened, it would fetch an uncropped version of the selected featured image via WP-JSON, extract the a palette of colours via [Vibrant.js](http://jariz.github.io/vibrant.js/), and then add these as a colour picker to the modal.

<p>So in the above code: I would be able to call a blog/blogs in each row, but it would the next blog in sequential order. So in this case: one that spans the whole browser and then 2 50% width ones right next to eachother, then repeat structure for more blogs.</p>
<p>Is this possible? Is there a way to make a variable or something that allows you to a call archives repeatedly while sequentially spitting out the archives and not repeating the same ones?</p>
<p>thanks in advance. </p>

I am trying to make my own version [of this](http://demo.codestag.com/ink/) I've implemented bootstrap grid in my attempt. I'm very close, but the `<div class="row">` being looped is causing problems.
I want to just be able to build my html structure with bootstrap and not rely soley on the `if` statements that control how many archives are spit out.
Is there a way to add as many `<?php the_post_thumbnail('category-thumbnail'); ?>` (for example) as I want so it sequentially spits out the blogs in order?
```
<?php
$count = 0;
while ( have_posts() ) : the_post();
if ( $count < 1 ) { ?>
<div class="row" style="margin-bottom:0px;">

So in the above code: I would be able to call a blog/blogs in each row, but it would the next blog in sequential order. So in this case: one that spans the whole browser and then 2 50% width ones right next to eachother, then repeat structure for more blogs.
Is this possible? Is there a way to make a variable or something that allows you to a call archives repeatedly while sequentially spitting out the archives and not repeating the same ones?
thanks in advance.

<p>I've got a basic text widget and, outside the standard <code><div class="textwidget"></code> wrapper there is a <code><li id="text-5" class="widget widget_text"></code> (which I have not added when creating the sidebar in <code>functions.php</code> or added when adding a text widget from the dashboard). </p>
<p>i.e. the full code looks like this:</p>
<pre><code><li id="text-5" class="widget widget_text">
<div class="textwidget">
<my content>
</div>
</li>
</code></pre>
<p>I'm at a loss where this <code>li</code> comes from. Any idea why and how I can get rid of it?</p>

I think WordPress widgets create li tags on default. If you want the bullet points removed you could fix that with a css approach.
```
.widget li {
list-style: none;
}
```

<p>So I have a client who wants a little extra that is beyond capabilities of my wordpress theme that I have purchased. I know through html, css and js I can create it from scratch (they want animations and a neat looking landing page). I was wondering if there was a way or any plugins that I can use to directly create a page using all of the code. Sorry if I am not explaining my question well! </p>

I was going about this the wrong way around. I needed to allow the user to select the date first and then the category.
I also needed to make the dropdown boxes auto select, so that the date search is performed first taking the user to the date archive and then the user can select the category they require.
```
<form class="my-filter" method="GET" action=""><div class="col-sm-12 text-center">
<span>Filter Posts by:</span>
<ul class="list-inline">
<?php $years = $wpdb->get_col("SELECT DISTINCT YEAR(post_date) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'post' ORDER BY post_date DESC");
$months = $wpdb->get_col("SELECT DISTINCT MONTHNAME(post_date) FROM $wpdb->posts WHERE post_status = 'publish' AND post_type = 'post' ORDER BY post_date DESC");?>
<li>
<select onChange="window.location.href=this.value">
<option value="" disabled selected> Date </option>
<?php foreach($months as $month) : ?>
<option value="<?php echo site_url() .'/'.date('Y') .'/'.date('m', strtotime($month))?>"> <?php echo '<ul><li class"list-unstyled">' . $month .'</li></ul>';?></option>
<?php endforeach; ?>
<?php foreach($years as $year) : ?>
<option value="<?php echo site_url() .'/'.$year ?>"><?php echo '<ul><li class"list-unstyled">' . $year .'</li></ul>';?></option>
<?php endforeach; ?>
</select>
</li>
<li>
<label>
<select onChange="window.location.href=this.value">
<option value="category" disabled selected> Category </option>
<?php foreach( $categorys as $category ) : ?>
<option value="?category=<?php echo $category->slug; ?>">
<?php echo $category->name; ?>
</option>
<?php endforeach; ?>
</select>
</label>
</li>
</ul>
</div>
</form>
```
Now the final url reads
```
http://mywebsite.com/2015/09/?category=special-events
```
To make sure that the query finds the category only for that month the $args must include a dynamic date\_query like this:
```
$m = get_the_time('m');
$y = get_the_time('Y');
$args = array(
'post_type' => array('post'),
'post_status' => 'publish',
'tax_query' => $cat_query,
'orderby' => 'date',
'order' => 'desc',
'date_query' => array(
array(
'year' => $y,
'month' => $m,
),
),
);
```

<p>Here's the query i have used.</p>
<pre><code> <?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;

<p>Is there any way to skip the first 3 posts only in the first page (?paged=1) and not the other pages (?paged=2....).</p>

Here's the query i have used.
```
<?php $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$wp_query = new WP_Query('order=asc&orderby=meta_value&meta_key=date&posts_per_page=6&paged=' . $paged); ?>
```
Is there any way to skip the first 3 posts only in the first page (?paged=1) and not the other pages (?paged=2....).
|
For skipping the post just use offset parameter in wp\_query.
To display latest three post :
```
<?php
$latestpost = new WP_Query('order=asc&orderby=meta_value&meta_key=date&posts_per_page=3');
//Here add loop to display posts like
while($latestpost->have_posts()) : $latestpost->the_post();
the_title();
the_content();
endwhile; wp_reset_query();
//After that skip three posts using offset
$latestpost = new WP_Query('order=asc&orderby=meta_value&meta_key=date&posts_per_page=6&offset=3&paged=' . $paged);
the_title();
the_content();
endwhile; wp_reset_query();
?>
```

Since WordPress is having trouble recognizing your custom template files, you could use this instead.
Insert into your `single.php` file. Based on your description above, it sounds like you don't have a `single.php` file so you will likely have to create one. If you do already have a `single.php` file then there is likely still some confusion with your exact problem because a custom post would only display the `index.php` template if there was no `single.php`. Or you could just be confusing the two.
```
<?php
if( get_post_type == 'acme_product' ) {
// Put the template code to display the custom post type post
} else {
// Code for all other posts
}
?>
```
This will work in any of the default WordPress post related template files like categories, archives, etc.

<p>My blog (Jetpack) sends out <code>512x512</code> favicon as <code>og:image</code>, because theme used does not support featured images and there are no images / gallery in the post itself. I'm forced to use favicons that large, because Wordpress / theme says:</p>
<blockquote>
<p>The Site Icon is used as a browser and app icon for your site. Icons must be square, and at least 512 pixels wide and tall.</p>
</blockquote>
<p>Is there any solution, that would allow me to block <code>og:image</code> tag <strong>only for favicon</strong> (i.e. if there will be any images directly in post text or if I change my theme to one, that supports featured images, I want them to be exported as <code>og:image</code>; I only want to block sending favicon / Site Icon through this tag).</p>
<p><strong>Edit</strong>: <em>As per <a href="https://jetpack.com/2013/10/15/add-a-default-fallback-image-if-no-image/" rel="nofollow">Jetpack Blog</a> I have assumed, that the quickest solution will be to ignore above text and set my favicon to i.e. <code>192x192</code>, which Facebook should ignore. However, some tests with <a href="https://developers.facebook.com/tools/debug/" rel="nofollow">Facebook Debugger</a> showed, that this not always works (image isn't sometimes ignored) and this will certainly not work for other kind of social sharing services. Thus, an ability to blog <code>og:image</code> tag for favicons / Site Icons becomes really necessary.</em></p>

My blog (Jetpack) sends out `512x512` favicon as `og:image`, because theme used does not support featured images and there are no images / gallery in the post itself. I'm forced to use favicons that large, because Wordpress / theme says:
>
> The Site Icon is used as a browser and app icon for your site. Icons must be square, and at least 512 pixels wide and tall.
>
>
>
Is there any solution, that would allow me to block `og:image` tag **only for favicon** (i.e. if there will be any images directly in post text or if I change my theme to one, that supports featured images, I want them to be exported as `og:image`; I only want to block sending favicon / Site Icon through this tag).
**Edit**: *As per [Jetpack Blog](https://jetpack.com/2013/10/15/add-a-default-fallback-image-if-no-image/) I have assumed, that the quickest solution will be to ignore above text and set my favicon to i.e. `192x192`, which Facebook should ignore. However, some tests with [Facebook Debugger](https://developers.facebook.com/tools/debug/) showed, that this not always works (image isn't sometimes ignored) and this will certainly not work for other kind of social sharing services. Thus, an ability to blog `og:image` tag for favicons / Site Icons becomes really necessary.*

Looking at your site now I can say that those open graph tags are from `Jetpack` Plugin.
---
If there is no image available in the post , Jetpack adds site-icon/favicon as the default one.
We can control output of tags using filters
* **`jetpack_open_graph_tags`**
* **`jetpack_images_get_images`**
* **`jetpack_open_graph_image_default`**
* **`jetpack_enable_open_graph`**
Remove only og:image
====================
Place the following code in `functions.php` of the active theme.
```
function wpse_228649_remove_image_tag( $tags ) {
unset( $tags['og:image'] );
return $tags;
}
add_filter( 'jetpack_open_graph_tags', 'wpse_228649_remove_image_tag' );
```
Stating from [Jetpack blog](https://jetpack.com/2013/10/15/add-a-default-fallback-image-if-no-image/)
Jetpack starts by looking for a Featured Image. If you didn’t define any, we will look for slideshows and galleries, and then for any images that may be attached to the post. If we don’t find any image attached to that post, we’ll look for single images you may have inserted in the post. If you’ve inserted an image that is hosted on another site, we can use it too.
However, sometimes you may not have added any image to your post.
In that case , we can set default image using the following code.
```
function wpse_203094_custom_image( $media, $post_id, $args ) {
if ( $media ) {
return $media;
} else {
$permalink = get_permalink( $post_id );
$url = 'YOUR_CUSTOM_DEFAULT_IMAGE_URL' ;
return array( array(
'type' => 'image',
'from' => 'custom_fallback',
'src' => esc_url( $url ),
'href' => $permalink,
) );
}
}
add_filter( 'jetpack_images_get_images', 'wpse_203094_custom_image', 10, 3 );
```
Or you can use filter to change the default one.
```
function wpse_203094_jetpack_default_image() {
return 'YOUR_IMAGE_URL';
}
add_filter( 'jetpack_open_graph_image_default', 'wpse_203094_jetpack_default_image' );
```
Or you can disable them entirely using:
```
add_filter( 'jetpack_enable_open_graph', '__return_false' );
```
Note
====
As **@cjbj** pointed out that some plugins like `Yoast SEO` can override open graph tags. The above filters/code works only for `Jetpack` assuming that no other plugins are overriding them.
Update
------
>
> Is there any solution, that would allow me to block og:image tag only for favicon
>
>
>
Yes there is , we can use [**`jetpack_images_get_images`**](https://github.com/Automattic/jetpack/blob/4.0.3/class.jetpack-post-images.php/#L496) filter.If we take a look at [**`jetpack_og_get_image`**](https://github.com/Automattic/jetpack/blob/4.0.3/functions.opengraph.php/#L340) src we can find that it adds core site icon like this
```
// Third fall back, Core Site Icon. Added in WP 4.3.
if ( empty( $image ) && ( function_exists( 'has_site_icon') && has_site_icon() ) ) {
$image['src'] = get_site_icon_url( 512 );
$image['width'] = '512';
$image['height'] = '512';
}
```
And finally defaults to blank image like this
```
// Finally fall back, blank image
if ( empty( $image ) ) {
/**
* Filter the default Open Graph Image tag, used when no Image can be found in a post.
*
* @since 3.0.0
*
* @param string $str Default Image URL.
*/
$image['src'] = apply_filters( 'jetpack_open_graph_image_default', 'https://s0.wp.com/i/blank.jpg' );
}
```
So as to make Jetpack assume that it has already got an image and there is no need to use `site icon`, we need to set some image.This can be done using the following code.Place this in `functions.php` of the active theme.
```
function wpse_203094_no_site_icon( $media, $post_id, $args ) {
if ( $media ) {
return $media;
} else {
return array( array(
'src' => '' // here we are conning Jetpack, Hurray!
) );
}
}
add_filter( 'jetpack_images_get_images', 'wpse_203094_no_site_icon', 10, 3 );
```

<p>I know how to style/change the font used depending on screen size with media queries and css.
What I don't know is how to prevent the custom fonts from loading in small screens.
I use google fonts and I enqueue them in functions.php, but I'm open to your workarounds. </p>

I think I have a great idea to make my site load faster in mobile: *"don't load the custom fonts in small screens"*
I know how to style/change the font used depending on screen size with media queries and css.
What I don't know is how to prevent the custom fonts from loading in small screens.
I use google fonts and I enqueue them in functions.php, but I'm open to your workarounds.
Btw, this how to do it, [when using @font](https://css-tricks.com/preventing-the-performance-hit-from-custom-fonts/)
|
WordPress has [`wp_is_mobile()`](https://codex.wordpress.org/Function_Reference/wp_is_mobile) function to detect mobile and handheld devices. You can use that to define your enqueue function to load fonts conditionally.
You can enqueue fonts for non mobile devices like this.
```
function my_enqueue_function() {
if ( !wp_is_mobile() ) {
wp_enqueue_style( 'gfonts', 'http://fonts.googleapis.com/css?family=Arbutus+Slab', false, NULL, 'all' );
}
}
add_action( 'wp_enqueue_scripts', 'my_enqueue_function' );
```

<p>I would like to change the image sizes for "medium" and "large". </p>
<p>I did change the sizes in Settings > Media </p>
<p><a href="https://i.stack.imgur.com/yD7ro.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yD7ro.png" alt="enter image description here"></a></p>
<p>This however does not seem to have any effect on the settings I see when I edit or insert an image:</p>
<p><a href="https://i.stack.imgur.com/q5eZY.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/q5eZY.png" alt="enter image description here"></a></p>
<p>I did empty cache and reset the browser.</p>
<p>I also changed the theme's settings for the custom image size and content_width accordingly – but this does not have any influence on what options are displayed under <em>Image Details</em>.</p>
<pre><code>add_image_size('full-width', 1600, 0, false);
if ( ! isset( $content_width ) ) $content_width = 1600;
</code></pre>
<p>Now I'm stuck – would appreciate any pointer… Thanks!</p>
<p>PS: I know there are plugins like <a href="https://wordpress.org/plugins/simple-image-sizes/" rel="nofollow noreferrer">Simple Image Sizes</a> that could be handy – but I would like to try to do this 'the right way' (if that makes any sence).</p>

Your image sizes need to be regenerated, as for the images to have different sizes they need to be cropped from the original and written to an actual file, whereas the settings only updates the settings, so will only affect future uploads. The [Regenerate Thumbnails](https://wordpress.org/plugins/regenerate-thumbnails/) plugin can help with fixing this.

`add_theme_support( 'title-tag' )` doesn't belong in your header template. It belongs in your `functions.php` file. Usually, it's best to wrap it in it's own function and hook it to `after_setup_theme` in order to allow plugins and child themes to override it later if they need to. So...
```
function wpse_add_title_support() {
add_theme_support( 'title-tag' );
}
add_action ( 'after_setup_theme', 'wpse_add_title_support' );
```
Once you have declared title support, you can remove the `<title>` tag from `header.php` altogether and WP will handle putting it in.

```
$paged = ( get_query_var( 'paged' ) ) ? get_query_var( 'paged' ) : 1;

// The Query
$query = new WP_Query( $args );
$attachments = get_posts( $args );

Page number or pagination not working, calling the function in my static page like so:
```

Dear I have wasted my week on this problem, basically when you select static page as your home page in setting->reading of wordpress the complete behavior of listing things are changed, basically static pages are never meant for pagination the fact is when you call the $paged variable it will always return zero even if you define its value to 1 the pagination will just refresh your page, because its a page not a .php valid file page is already a taxonomy function that is called in index.php of main wordpress the function will always return same thing no matter what you do,
The work around make a index.php file copy all the content from that static page to it and then replace it with your index.php and select latest post in setting->reading of wordpress
Now if you really don't want to mess with it, but still want to have the pagination then you need to write a small code of yours for pagination
basically home.com/page/2 will never work but home.com/?page=2 will always work but changing the permalink structure will change it for every thing so we will create a pagination function that will call next page with home.com/?page=2 structure url
```
/* ------------------------------------------------------------------*/
/* PAGINATION */
/* ------------------------------------------------------------------*/
//paste this where the pagination must appear
global $wp_query;
$total = $wp_query->max_num_pages;
// only bother with the rest if we have more than 1 page!
if ( $total > 1 ) {
// get the current page
if ( !$current_page = get_query_var('paged') )
$current_page = 1;
// structure of "format" depends on whether we're using pretty permalinks
if( get_option('permalink_structure') ) {
$format = '?paged=%#%';
}
echo paginate_links(array(
'base' => get_pagenum_link(1) . '%_%',
'format' => $format,
'current' => $current_page,
'total' => $total,
'mid_size' => 4,
'type' => 'list'
));
}
```
if you include this code where this rather than the current pagination you will see it working :)

<p>There seems to be a ton of information on checking a <code>meta_key</code> against an array of <code>meta_values</code>, but I want to do the opposite. </p>
<p>I have a site with projects, and press reviews. When the client adds a review, they have a custom field (ACF) to select the project it relates to from a list. </p>
<p>I am now trying to display all press reviews that relate to a certain project, together on a page. I have the project ID, and use a query with $args to select the press reviews I want.</p>
<p>My current <code>$args</code>: </p>
<pre><code>$args = array(
'post_type' => 'pressreview',
'order' => DESC,
'meta_query' => array(
array(
'key' => 'belongs_to_project',
'value' => $projectID,
'compare' => 'LIKE'
)
)
);
</code></pre>
<p>The problem is, that custom field '<code>belongs_to_project</code>' returns an array with IDs. One press review can be about multiple projects, so I let the client pick multiple projects from the list in that field. A typical array will be like this: </p>
<pre><code>Array ( [0] => 210 [1] => 202 ).
</code></pre>
<p>What I want to do, is check whether the <code>$projectID</code> is in that array. </p>
<p>In the current setup, it sort of works: if the client selected 202 and 210 from the list, and the <code>$projectID</code> is <code>210</code>, the press review is shown. However, if the <code>$projectID = 20</code>, we get press reviews for projects <code>201</code>, <code>202</code>, <code>203</code>, etc. (since those numbers include '<code>20</code>', which is how <code>LIKE</code> works)</p>
<p>Is there any way I can tell this query to only check for 'whole' numbers? So that "2" would only show reviews for project <code>2</code>, and not for <code>201</code>, <code>202</code>, or any other numbers that have a 2 in them? </p>
<p>I've seen there is a <code>REGEXP</code> option to use instead of <code>LIKE</code>, but I can't find out how to use it in a way that it checks for only 'whole numbers'.</p>
<p>I've also tried '<code>IN</code>', but that doesn't work at all here.</p>
<p>One thing that I thought of, but don't know whether it's possible at all, is to use something like:</p>
<pre><code>'key' => 'belongs_to_project[$i]'
</code></pre>
<p>with some kind of loop through the key values, so that <code>$projectID</code> could be checked with <code>'='</code> instead of <code>LIKE</code> against each of the values in the array of the custom field.
I've no idea if there's any such option and how it should be written.</p>
<p>Hope my explanation is clear enough, please let me know if I need to explain better.</p>

There seems to be a ton of information on checking a `meta_key` against an array of `meta_values`, but I want to do the opposite.
I have a site with projects, and press reviews. When the client adds a review, they have a custom field (ACF) to select the project it relates to from a list.
I am now trying to display all press reviews that relate to a certain project, together on a page. I have the project ID, and use a query with $args to select the press reviews I want.
My current `$args`:
```
$args = array(
'post_type' => 'pressreview',
'order' => DESC,
'meta_query' => array(
array(
'key' => 'belongs_to_project',
'value' => $projectID,
'compare' => 'LIKE'
)
)
);
```
The problem is, that custom field '`belongs_to_project`' returns an array with IDs. One press review can be about multiple projects, so I let the client pick multiple projects from the list in that field. A typical array will be like this:
```
Array ( [0] => 210 [1] => 202 ).
```
What I want to do, is check whether the `$projectID` is in that array.
In the current setup, it sort of works: if the client selected 202 and 210 from the list, and the `$projectID` is `210`, the press review is shown. However, if the `$projectID = 20`, we get press reviews for projects `201`, `202`, `203`, etc. (since those numbers include '`20`', which is how `LIKE` works)
Is there any way I can tell this query to only check for 'whole' numbers? So that "2" would only show reviews for project `2`, and not for `201`, `202`, or any other numbers that have a 2 in them?
I've seen there is a `REGEXP` option to use instead of `LIKE`, but I can't find out how to use it in a way that it checks for only 'whole numbers'.
I've also tried '`IN`', but that doesn't work at all here.
One thing that I thought of, but don't know whether it's possible at all, is to use something like:
```
'key' => 'belongs_to_project[$i]'
```
with some kind of loop through the key values, so that `$projectID` could be checked with `'='` instead of `LIKE` against each of the values in the array of the custom field.
I've no idea if there's any such option and how it should be written.
Hope my explanation is clear enough, please let me know if I need to explain better.
|
The solution was that I need to compare the literal value of `$projectID`, so that `LIKE` compares an exact string instead of just numbers. To make `$projectID` literal, it needs to be wrapped in quotes.
So, I changed this line:
`'value' => $projectID,`
to:
`'value' => '"'.$projectID.'"',`
Which solves the problem.

<p>I have this plugin I created that has a custom post type and a template file that renders the posts.
I want to be able to render the template in any page using a short code. So what I created was this piece of code which I am sure is wrong and would totally appreciate it if someone could answer how I am supposed to render the template </p>
<pre><code>function display_timeline(){
ob_start();
locate_template(plugin_dir_path( __FILE__ ) . '/timelines.php', true, false);
$ret = ob_get_contents();
ob_end_clean();
return $ret;
}
add_shortcode( 'wptimeline_display', 'display_timeline' );
</code></pre>
<p>Also, the template and the plugin functions are both in the same directory. </p>

[`locate_template()`](http://wpseek.com/function/locate_template/) only look for a specific template in themes, not in plugins, so your function wil never work. This also goes for [`get_template_part()`](https://developer.wordpress.org/reference/functions/get_template_part/) which is in essence just a wrapper function for `locate_template()`.
You will need to use funtions like [`file_exists()`](http://php.net/manual/en/function.file-exists.php) to check whether or not the required template exists and then use something like [`include()`](http://php.net/manual/en/function.include.php) to load your template. You can use the above to write your own function like `locate_template()`, this is at least what I will do, and have a fallback to lacate a template in themes should the template not exist in the plugin.
Just a note, always always first check if a value/template/condition exists before doing something with it. This will avoid unnecessary bugs and issues should a failure occur. Also, have something in place like returning false, adding a redirect, exiting etc etc to safely handle your code should you have a failure

<p>Ive got a CPT and in my CPT's argument I am calling the taxonomy <code>post_tag</code>. When I create a <code>tag.php</code> file it doesn't show any of the posts for said tag. My <code>tag.php</code>:</p>

I figured it out thanks to [Pieter's comment](https://wordpress.stackexchange.com/questions/203239/tag-php-not-displaying-posts-with-the-tag#comment295054_203239):
In `functions.php` I added:

function tag_filter($query) {
if ( !is_admin() && $query->is_main_query() ) {
if ($query->is_tag) {
$query->set('post_type', array( 'custom_post_type', ));
}
}
}
add_action('pre_get_posts','tag_filter');

You should use `'orderby' => 'meta_value_num'` and `'meta_key' => 'rating'` as specified by the WordPress Codec. Using `meta_value_num` with the assumption your ratings are numeric values

<p>I have just started playing with the WP REST API and found that when querying posts that there is a limit of 10 post per page unless specified. What I would like to know if is is possible to return the total number of post in a category though meta data or something similar?</p>

I have just started playing with the WP REST API and found that when querying posts that there is a limit of 10 post per page unless specified. What I would like to know if is is possible to return the total number of post in a category though meta data or something similar?
|
To just know the number of posts in a category, its endpoint returns that number straightforward, in example:
```
curl http://wired.com/wp-json/wp/v2/categories/24
```
In the resource returned, the `count` field says: 486
Which is the same number the metadata says about the total number of posts, if you request the posts in that category, rather than the category itself:
```
curl -I http://wired.com/wp-json/wp/v2/posts?categories=24
```
You can read the header `X-WP-Total: 486`.
REST API of WordPress follows best practices in use today for APIs, among others, return metadata about a request in the headers, plus links to traverse the collection if it is possible.
There is no need to wait for an array of posts of length === 0 in order to know there are no more pages of posts.
Actually, the rest API return in headers, metadata about the number of pages and total of posts available to this same endpoint/filter.
For example, take the API of wired.com:
```
curl -I http://wired.com/wp-json/wp/v2/posts/
```
It returns three headers relevant to this question:
```
Link: <http://www.wired.com/wp-json/wp/v2/posts?page=2>; rel="next"
X-WP-TotalPages: 18067
X-WP-Total: 180664
```
As you can see, the results are consistent enough to know if you need to retrieve more posts or you have reached the end of the listing. You have X-WP-Total showing total of resources for this endpoint, X-WP-TotalPages showing number of pages with the same number of posts (default is 10, but you can request more with query argument `per_page`).
And the Link header gives you even more information which you can use to traverse without even storing the total number of posts before requesting more.
For example: `$ curl -I http://www.wired.com/wp-json/wp/v2/posts?page=18067`
Gives you this Link header:
```
Link: <http://www.wired.com/wp-json/wp/v2/posts?page=18066>; rel="prev"
```
(No `next` link, just as first page has not `prev` link).
And an intermediate page: `$ curl -I http://www.wired.com/wp-json/wp/v2/posts?page=2`
Gives you next and prev links:
```
Link: <http://www.wired.com/wp-json/wp/v2/posts?page=1>; rel="prev", <http://www.wired.com/wp-json/wp/v2/posts?page=3>; rel="next"
```
I'd suspect the number of posts REST API can return is more related to server capabilities, since I've being able to return `per_page=100` without any trouble.

<p>I am trying to add css code into head tag. the css style is from shortcodes. title text from shortcode and title color / font size.. etc.
This is an example.</p>
<pre><code><html>
<head>
<?php wp_head(); ?>
.................. (some style, js) ..................
/* I want to put all of css styles into head tag from into body tags */
</head>
<body>
<?php
//shortcode css from user custom option
add_action( 'wp_head', 'iulia_example' );
function iulia_example() {
echo '<style type="text/css">
.sc_title {color:#fff; font-weight:600;}
</style>';
}
?>
<!-- shortcode -->
<div class="sc_wrap">
<h1 class="sc_title">Hello This is the title</h1>
</div>
</body>
</html>
</code></pre>
<p>I want to use wp_head hook to place css style in head tag. however it's not working.
Is there another way to add the css code in head? wp_head is not working in "body tag" and it gets the custom css variables from shortcode and it's in BODY.</p>
<p>Thank you,</p>

I want to use wp\_head hook to place css style in head tag. however it's not working.
Is there another way to add the css code in head? wp\_head is not working in "body tag" and it gets the custom css variables from shortcode and it's in BODY.
Thank you,

It's not working because you're calling add\_action after the actual action is fired. If you move the action declaration before wp\_head() it will work:
```
<html>
<head>
<?php
add_action( 'wp_head', function () {
echo '<style type="text/css">.sc_title {color:#fff; font-weight:600;}</style>';
});
?>
<?php wp_head(); ?>
```
There's no easy way to add some code to the head from the body tag as that code would be evaluated later. If you really need to do so you can play with [output buffering](http://php.net/manual/en/function.ob-start.php) (evaluate first the body template and buffer it) but I can't see why you should.
**In reply to the latests comments:**
If I've understood right what you want to achieve is to have some css being put in the head when a shortcode is add in the content, right? In that case you might add a check in the header for the content of the post. If it match a given shortcode then you output your styles. You can add something like the following to your functions.php, but it's kind of an hack:
```
add_action('wp_head', function () {
global $post;
if ($post) {
setup_postdata($post);
$content = get_the_content();
preg_match('/\[my_shortcode\]/', $content, $matches);
if ($matches) {
echo '<style>.some_style { font-weight:800; }</style>';
}
}
});

<p>In my site I've does some coding based on the category like <code>in_category('featured')</code> do something. Now, this is only applicable to posts only.

<p>Now I know that this question has been discussed before here many time, but not exactly what I'm looking for. So before downgrading this question, red it properly.</p>
<p>Here in this post <a href="https://wordpress.stackexchange.com/questions/31553/is-there-a-quick-way-to-hide-category-from-everywhere">is there a quick way to hide category from everywhere?</a> the following function is provided to exclude some categories, but I don't want to exclude it I just want to hide it.</p>

In my site I've does some coding based on the category like `in_category('featured')` do something. Now, this is only applicable to posts only. Also the posts which is associated with `featured` category is also associated with other category too. As it is only associated with `featured` category to show up with special design thats it.
Now I know that this question has been discussed before here many time, but not exactly what I'm looking for. So before downgrading this question, red it properly.
Here in this post [is there a quick way to hide category from everywhere?](https://wordpress.stackexchange.com/questions/31553/is-there-a-quick-way-to-hide-category-from-everywhere) the following function is provided to exclude some categories, but I don't want to exclude it I just want to hide it.
```
add_action('pre_get_posts', 'wpa_31553' );
function wpa_31553( $wp_query ) {
//$wp_query is passed by reference. we don't need to return anything. whatever changes made inside this function will automatically effect the global variable
$excluded = array(272); //made it an array in case you need to exclude more than one
// only exclude on the front end
if( !is_admin() ) {
$wp_query->set('category__not_in', $excluded);
}
}
```
As an example let's say a post is associated with `featured` category and also associated with `Work` category. Now as `featured` is alphabetically comes first the breadcrumb (using Yoast SEO Breadcrumb) will show `featured` as category name also the post meta (shown below the posts) will show up both category names i.e. `featured` and `work`.
That is why I want to hide the `featured` category completely so that no front end user will ever have idea that `featured` category exists. It wont show up in breadcrumb, post meta, post category list, no where. It will remain hidden but in the backend code it will still work when I try to do specific with those posts inside `featured` category using `in_category('featured')`.
Does anyone know how to obtain this category hiding (not excluding) feature.

Replace all the call to in\_category('featured') with the custom function inCategory('featured'), declare it on your functions.php:
```
/**
* @param string $category
*
* @return bool
*/
function inCategory($category)
{
global $wpdb, $post;
if ( ! $post) {
return false;
}
$query = $wpdb->prepare("SELECT COUNT(t.term_id)
FROM $wpdb->terms AS t
INNER JOIN $wpdb->term_taxonomy AS tt ON tt.term_id = t.term_id
INNER JOIN $wpdb->term_relationships AS tr ON tr.term_taxonomy_id = tt.term_taxonomy_id
WHERE tr.object_id = %d
AND tt.taxonomy = '%s'
AND t.slug = '%s'
", $post->ID, 'category', $category);
return (bool) $wpdb->get_var($query);
}
```
The add the following filters:
```
/**
* @param array $terms
*
* @return array
*/
function remove_featured_category_from_frontend(array $terms)
{
if ( ! is_admin()) {
$terms = array_filter($terms, function ($term) {
if ($term->taxonomy === 'category') {
return $term->slug !== 'featured';
}
return true;
});
}
return $terms;
}
add_filter('get_terms', 'remove_featured_category_from_frontend');
add_filter('get_object_terms', 'remove_featured_category_from_frontend');
```
Give it a try and let me know.

<p>Change title separator.</p>
<p>I'm working with the underscores starter theme. I want to make a small change to the title. Change the separator from

UPDATE for WordPress 4.4
------------------------
Since WordPress 4.4 the `wp_title` filter doesn't work because `wp_title()` function is not used in core anymore. That function was marked as deprecated, then reinstated until new notice but [theme authors are discouraged from using it](https://make.wordpress.org/core/2015/10/20/document-title-in-4-4/). Because of that, `wp_title` filter still will work if you continue using `wp_title()` function directly in your theme but it is not recommended.
There are new filters to customize the document title when theme support for `title-tag` is enabled:
1. [`pre_get_document_title`](https://developer.wordpress.org/reference/hooks/pre_get_document_title/)
2. [`document_title_parts`](https://developer.wordpress.org/reference/hooks/document_title_parts/)
3. [`document_title_separator`](https://developer.wordpress.org/reference/hooks/document_title_separator/).
As you only want to customize the separator, you can use `document_title_separator` as follow:
```
add_filter( 'document_title_separator', 'cyb_document_title_separator' );
function cyb_document_title_separator( $sep ) {
$sep = "-";
return $sep;
}
```
Previous answer
---------------
You can use [`wp_title` filter](https://codex.wordpress.org/Plugin_API/Filter_Reference/wp_title) to customize the `<title>` tag.
```
add_filter( 'wp_title', 'customize_title_tag', 10, 3 );
function customize_title_tag( $title, $sep, $seplocation ) {
// Customize $title here.
// Example taken from https://generatepress.com/forums/topic/title-tag-separator/
$title = str_replace( '|', '-', $title );
return $title;
}
```
A more complex example of how to use this filter (taken from TwentyTwelve theme):
```
function twentytwelve_wp_title( $title, $sep ) {
global $paged, $page;
if ( is_feed() )
return $title;
// Add the site name.
$title .= get_bloginfo( 'name' );
// Add the site description for the home/front page.
$site_description = get_bloginfo( 'description', 'display' );
if ( $site_description && ( is_home() || is_front_page() ) )
$title = "$title $sep $site_description";
// Add a page number if necessary.
if ( $paged >= 2 || $page >= 2 )
$title = "$title $sep " . sprintf( __( 'Page %s', 'twentytwelve' ), max( $paged, $page ) );
return $title;
}
add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );
```

<p>I am using <a href="https://github.com/WebDevStudios/CMB2" rel="nofollow">CMB2</a> for metabox on custom posts. I am adding a metabox by using code below:</p>
<pre><code>$cmb_demo->add_field( array(

'desc' => __( 'field description (optional)', 'cmb2' ),
'id' => $prefix . 'text',
'type' => 'text',
'show_on_cb' => 'show_this_field_if_true',
) );
</code></pre>
<p>I understand show_this_field_if_true will be a function that will return true or false. But, I want to make this as conditional with another field. This field will show if another field's value is true. </p>
<p>Here is an example that Don't show this field if it's not the front page template</p>
<pre><code>function show_this_field_if_true( $cmb ) {

The best way to do this is by using JavaScript and there is a couple of CMB2 plugins let you do that easily:

When using hooks such as [`wp_enqueue_scripts`](https://codex.wordpress.org/Function_Reference/wp_enqueue_script) you have access to [Conditional Tags](https://codex.wordpress.org/Conditional_Tags). This allows you to only enqueue certain things on certain pages, templates, taxonomies, etc.
By default, WordPress accepts two template files as the natural blog:
1. `index.php`
2. `home.php`
You can read more about this in the [Template Hierarchy](https://developer.wordpress.org/themes/basics/template-hierarchy/#home-page-display) post, while it does say "Home" this will only take the place of the homepage if `front-page.php` does not exist in your theme. What you have is a [Page Template](https://developer.wordpress.org/themes/basics/template-hierarchy/#page) as your "Blog" and **not the standard** you need to use `is_page()`:
```
/**

function theme_name_scripts() {
if( is_page( 'blog' ) ) { // Only add this style onto the Blog page.
wp_enqueue_style( 'style-name', get_stylesheet_uri() );

Assuming you are using Linux or OS X, the easiest way is probably to use wp-cli (if present in your WordPress installation) to return a list of all posts:
```
wp-cli post list
```
Then pipe it to the word count tool to get the number of lines:
```
wc -l
```
Finally, deduct one to take care of the header line which is not a post:
```
awk '{print $1-1}'
```
So, in one line:
```
wp-cli post list | wc -l | awk '{print $1-1}'
```

[`get_home_path()` only works when WP admin scripts are loaded.](https://codex.wordpress.org/Function_Reference/get_home_path)
`ABSPATH` is [defined in wp-config.php](https://core.trac.wordpress.org/browser/trunk/wp-config-sample.php#L84) so works anytime after the config file is loaded, so it should be totally fine for your use.
It is set to the `dirname(__FILE__) + trailing slash` of wp-load.php (same location as e.g. wp-config.php). `dirname` here returns the absolute path where WordPress is installed. For example, `/home/user/public_html` and `ABSPATH` adds a trailing slash
```
/** Absolute path to the WordPress directory. */
if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');
// So,
ABSPATH == '/home/user/public_html/'; // WP files are in public_html
```
So if you have a folder structure such as this:
```
- public_html/
- - wp-admin/
- - wp-content/
- - wp-includes/
- - wp-config.php
- - wp-load.php
- - vendor/
- - - autoload.php
- ...
```
You can put the following in your theme's functions.php file to load the autoload.php file
```
require_once( ABSPATH . 'vendor/autoload.php' );
```

<p>I want to add a media uploader to a plugin.</p>
<p>I have found and read
<a href="https://stackoverflow.com/a/28549014/3115317">This</a></p>
<p>It does shows the media uploader and it let's me select an image but as it uploads it gives me some crappy error: <code>Error occurred during upload. Try again later.</code><br>
This might be slight off because I translated it.</p>
<p>I don't know how to search for the real error here.<br>
Can anyone tell me how to find it?</p>
<pre><code><?php
wp_enqueue_script('jquery');
wp_enqueue_media();
?>
<div>
<label for="image_url">Image</label>
<input type="text" name="image_url" id="image_url" class="regular-text">
<input type="button" name="upload-btn" id="upload-btn" class="button-secondary" value="Upload Image">
</div>
<script type="text/javascript">
jQuery(document).ready(function($){
$('#upload-btn').click(function(e) {
e.preventDefault();
var image = wp.media({
title: 'Upload Image',
multiple: false
}).open()
.on('select', function(e){
var uploaded_image = image.state().get('selection').first();
console.log(uploaded_image);
var image_url = uploaded_image.toJSON().url;
$('#image_url').val(image_url);
});
});
});
</script>
</code></pre>
<p>If it is possible I would like to add an items to the Media Uploader:<br>
Choose a folder to upload the file to.<br>
Not by the person who is uploading but just a folder I create before the upload</p>
<p>M.</p>
<p>---------------------------------------<br>
UPDATE:<br>
Weird thing happend<br>
I have disabled the WP_DEBUG function and now everything is working. If I set it to <code>true</code> there are no errors...</p>

I want to add a media uploader to a plugin.
I have found and read
[This](https://stackoverflow.com/a/28549014/3115317)
It does shows the media uploader and it let's me select an image but as it uploads it gives me some crappy error: `Error occurred during upload. Try again later.`
This might be slight off because I translated it.
I don't know how to search for the real error here.
Can anyone tell me how to find it?
```
<?php
wp_enqueue_script('jquery');
wp_enqueue_media();
?>
<div>
<label for="image_url">Image</label>
<input type="text" name="image_url" id="image_url" class="regular-text">
<input type="button" name="upload-btn" id="upload-btn" class="button-secondary" value="Upload Image">
</div>
<script type="text/javascript">
jQuery(document).ready(function($){
$('#upload-btn').click(function(e) {
e.preventDefault();
var image = wp.media({
title: 'Upload Image',
multiple: false
}).open()
.on('select', function(e){
var uploaded_image = image.state().get('selection').first();
console.log(uploaded_image);
var image_url = uploaded_image.toJSON().url;
$('#image_url').val(image_url);
});
});
});
</script>
```
If it is possible I would like to add an items to the Media Uploader:
Choose a folder to upload the file to.
Not by the person who is uploading but just a folder I create before the upload
M.
---------------------------------------
UPDATE:
Weird thing happend
I have disabled the WP\_DEBUG function and now everything is working. If I set it to `true` there are no errors...
|
Try using this code:
```
define("ME_URL", rtrim(WP_PLUGIN_URL,'/') . '/' . basename(dirname(__FILE__)));
define("ME_DIR", rtrim(dirname(__FILE__), '/'));
function my_admin_scripts() {
wp_enqueue_script('media-upload');
wp_enqueue_script('thickbox');
}
function my_admin_styles() {
wp_enqueue_style('thickbox');
}
add_action('admin_print_scripts', 'my_admin_scripts');
add_action('admin_print_styles', 'my_admin_styles');
```
```
<td>
<img src="<?php echo esc_attr( get_the_author_meta( 'profileimage', $user->ID ) ); ?>" id="ppimage">
<input type="text" name="profileimage" id="profileimagetxt" value="<?php echo esc_attr( get_the_author_meta( 'profileimage', $user->ID ) ); ?>" class="regular-text" /><br />
<input type="button" id="profileimage" value="Upload Image">
<span class="description"><?php _e("profileimage"); ?></span>
</td>
</tr>
<script type="text/javascript">
$ = jQuery.noConflict();
$(document).ready(function($){
$('#profileimage').live('click',function() {
formfield = $('#upload_image').attr('name');
tb_show('', 'media-upload.php?type=image&TB_iframe=true');
return false;
});
window.send_to_editor = function(html) {
imgurl = $('img',html).attr('src');
$('#profileimagetxt').val(imgurl);
$('#ppimage').attr('src',imgurl);
tb_remove();
}
});
</script>
```
Hope it works for you :)

**Edit:** Note that I don't have access to run arbitrary code on the server. Basically, I have PHP, MySQL, FTP, and that's it.

Here's how it can be done, by temporarily making a minor fixup to the WP code:
1. Upload the zip file to the root folder of WP, in the same folder as `wp-config.php` and friends.
2. Open the file `wp-admin\includes\update.php`.
3. Find the function `find_core_update`, and change it to:
```
function find_core_update( $version, $locale ) {
$updates = get_core_updates();
return $updates[0];
}
```
4. Find the function `get_core_updates`, and change it to:
```
function get_core_updates( $options = array() ) {
$new_zip = 'wordpress-4.3.1.zip';
$new_version = '4.3.1';
return array((object)array(
'response' => 'upgrade',
'current' => $new_version,
'download' => '../' . $new_zip,
'packages' => (object) array (
'partial' => null,
'new_bundled' => null,
'no_content' => null,
'full' => '../' . $new_zip,
),
'version' => $new_version,
'locale' => null
));
}
```
Set the `$new_zip`, `$new_version` variables as needed.
5. Go to the admin panel and run the update!

`load_textdomain( 'themename', get_template_directory() . '/languages' );`
aforementioned warning doesn't show up.
I have uploaded required .po and .mo files in `themename/languages` folder.

If you want to use **load\_textdomain** you must also specify the file name:
```
function my_custom_locale()
{
load_textdomain('my-name', get_stylesheet_directory().'/languages/my-name-
'.get_locale().'.mo');
}
add_action('after_setup_theme', 'my_custom_locale');
```
In my example I added custom translations used in additional template files placed inside the **theme-child** folder, where I also added the **languages** files folder (es. my-name-it\_IT.mo, my-name-en\_GB.mo).
I added the code in the function.php file of the child-theme.

I have 2 custom post types "Shops" and "Restaurants".
Each of these have custom fields associcated with them.
For example, One field in Shops is "Shop ID" and one in Restaurants is "Restaurant ID".
I want to query both Custom Post Types and if Shop ID is 20, I want to display all Restaurants with ID 20.
I've been toying with this code:
```
<?php
$args = array(
'numberposts' => -1,
'post_type' => 'shops', 'restaurants',
'meta_query' => array(
'relation' => 'AND',
array(
'meta_key' => 'shop-id',
'meta_value' => '12345',
'compare' => '='
),
array(
'meta_key' => 'restaurant-id',
'meta_value' => '12345',
'type' => 'NUMERIC',
'compare' => '>'
)
)
);
// query
$the_query = new WP_Query( $args );
?>
<?php if( $the_query->have_posts() ): ?>
<?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
<h4>
<a href="<?php the_permalink(); ?>">
<?php the_title(); ?>
</a>
</h4>
<?php endwhile; ?>
<?php endif; ?>
```
Note I'm also using Advanced Custom Fields.

There's some contradiction between your question and the code you provided, so I'm not exactly sure which of two scenarios you're dealing with.
Scenario 1 - You want to show all Shops with a specific value for `shop-id` and all Restaurants with the same specific value for `restaurant-id`. Let's say that value is 20. You can do this with a single `WP_Query()` loop that looks for both post types where either custom field has the specified value. This assumes that Shops will never have a value for `restaurant-id` and vice-versa.
```
$args = array(
'posts_per_page' => -1,
'post_type' => array( 'shop', 'restaurant' ),
'meta_query' => array(
'relation' => 'OR',
array(
'key' => 'restaurant-id',
'value' => 20,
'compare' => '='
),
array(
'key' => 'shop-id',
'value' => 20,
'compare' => '='
)
)
);
$query = new WP_Query( $args );
```
Scenario 2 - You want to show all Shops, each Shop followed by all Restaurants that have the same value for `restaurant-id` as the value of the current Shop's `shop-id`.
```
$shops = new WP_Query(
array(
'posts_per_page' => -1,
'post_type' => 'shop'
)
);
if ( $shops->have_posts() ) {
while ( $shops->have_posts() ) {
$shops->the_post();
...
$shop_id = get_post_meta( $post->ID, 'shop-id', true );
$restaurants = new WP_Query(
array(
'posts_per_page' => -1,
'post_type' => 'restaurant',
'meta_query' => array(
array(
'key' => 'restaurant-id',
'value' => $shop_id,
'compare' => '='
)
)
)
);
if ( $restaurants->have_posts() ) {
while ( $restaurants->have_posts() ) {
$restaurants->the_post();
...
}
}
}
}
```

<p>I have a very simple JS script called <code>script_1.js</code> sitting at the root level of my twentytwelve-child theme. This script contains only:</p>

I have a very simple JS script called `script_1.js` sitting at the root level of my twentytwelve-child theme. This script contains only:
```
$(document).ready(function(){console.log("scriptLoaded");
});
```
and I've loaded it with the `functions.php`:
```
function theme_enqueue_styles() {
wp_enqueue_style( 'parent-style',
get_template_directory_uri() . '/style.css'

wp_enqueue_script( 'my_script' );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
add_action( 'wp_enqueue_scripts', 'wpb_adding_scripts' );
```
Now, I read the documentation and I found that if I want to put jQuery first, I have to use the above syntax, hence `array( 'jquery' )`.
The problem is, that it still doesn't work and in the console I still get the usual:
```
TypeError: $ is not a function
$(document).ready(function(){
```
There is a link where you can see the problem occurring, [here it is](http://antonioborrillo.co.uk/andys/) (error in the console).
Does anybody know why this isn't working? Did I incorrectly enqueue jQuery or something?
I've seen a few examples, like [this one](https://wordpress.stackexchange.com/questions/48530/how-do-i-make-script-load-after-jquery) and that's where I took inspiration from, but no joy.

Try two things -
1. Link your js using `wp_enqueue_script` action as under :
```
add_action( 'wp_enqueue_scripts', 'theme_name_scripts' );
function theme_name_scripts() {
wp_enqueue_script( 'script-name', get_template_directory_uri() . '/js/example.js', array('jquery'), '', true);
}
```
Third parameter in wp\_enqueue\_script() function will make sure jquery is loaded before your current js file.
2. Inside your js file, replace `$` with `jQuery` as :
jQuery(document).ready(function(){console.log("scriptLoaded");
});

I got the same problem.
**Solution 1:**
Strip your data.. Wordpress rejects the query if the length of value is greater than the field length defined on the database.
On your insert query, the value for **post\_type** field exceeded the 20 character limit.
**Solution 2:**
Use the $wpdb->query method

I use the below code . But the code display Thumbnail in the five number column. How to move it first column position?
```
//show Thumbnail in dashboard
function my_function_admin_bar(){ return false; }
add_filter( 'show_admin_bar' , 'my_function_admin_bar');
add_image_size( 'admin-list-thumb', 80, 80, false );
add_filter('manage_posts_columns', 'tcb_add_post_thumbnail_column', 1);
add_filter('manage_pages_columns', 'tcb_add_post_thumbnail_column', 1);
function tcb_add_post_thumbnail_column($cols){
$cols['tcb_post_thumb'] = __('Thumbnail');
return $cols;
}
add_action('manage_posts_custom_column', 'tcb_display_post_thumbnail_column', 1, 2);
add_action('manage_pages_custom_column', 'tcb_display_post_thumbnail_column', 1, 2);
function tcb_display_post_thumbnail_column($col, $id){
switch($col){
case 'tcb_post_thumb':
if( function_exists('the_post_thumbnail') )
echo the_post_thumbnail( 'admin-list-thumb' );
else
echo 'Not supported in theme';
break;
}
}
```

You can add featured image thumbnail in post column with this code.
Copied from here [Add Featured Post Thumbnails to WordPress Admin Post Columns](http://wpcodesnippet.com/add-featured-post-thumbnails-to-post-columns/).
Haven't tried it myself but it must work.
```
add_image_size( 'admin-list-thumb', 80, 80, false );
// add featured thumbnail to admin post columns
function wpcs_add_thumbnail_columns( $columns ) {
$columns = array(
'cb' => '<input type="checkbox" />',
'featured_thumb' => 'Thumbnail',
'title' => 'Title',
'author' => 'Author',
'categories' => 'Categories',
'tags' => 'Tags',
'comments' => '<span class="vers"><div title="Comments" class="comment-grey-bubble"></div></span>',
'date' => 'Date'
);
return $columns;
}
function wpcs_add_thumbnail_columns_data( $column, $post_id ) {
switch ( $column ) {
case 'featured_thumb':
echo '<a href="' . get_edit_post_link() . '">';
echo the_post_thumbnail( 'admin-list-thumb' );
echo '</a>';
break;
}
}
if ( function_exists( 'add_theme_support' ) ) {
add_filter( 'manage_posts_columns' , 'wpcs_add_thumbnail_columns' );
add_action( 'manage_posts_custom_column' , 'wpcs_add_thumbnail_columns_data', 10, 2 );
add_filter( 'manage_pages_columns' , 'wpcs_add_thumbnail_columns' );
add_action( 'manage_pages_custom_column' , 'wpcs_add_thumbnail_columns_data', 10, 2 );
}
```
**EDIT**
Just tried it and it's working fine.
Although it works fine out of the box but you can change thumbnail size in above code if you want to use your custom defined image size.
**EDIT**
Just fixed this code for 80x80 thumbnail.

<p>Total wordpress beginner here. I purchased a organicfood theme and when I got an updated version for it, among other files I also found organicfood child theme zip in main directory.</p>
<p>I know that organicfood.zip contains the updated version of parent theme but I don't know if same goes for organicfood child theme zip. Is the child zip added with every update just so that a new buyer has that default child theme template?</p>

<p>Plugin in question: <a href="http://dimsemenov.com/plugins/royal-slider/wordpress/" rel="nofollow">http://dimsemenov.com/plugins/royal-slider/wordpress/</a></p>
<p>Background: This is a great plugin, and it features a 'post' version where the slider pulls content from posts. However, the taxonomy for the posts that it's pulling has to be set at the slider settings level in WordPress, it can't be done via shortcode (that we know of). The plugin author does offer a way to override the default query here: <a href="http://help.dimsemenov.com/kb/wordpress-royalslider-advanced/wp-modifying-order-of-posts-in-slider" rel="nofollow">http://help.dimsemenov.com/kb/wordpress-royalslider-advanced/wp-modifying-order-of-posts-in-slider</a></p>
<p>Aim: create a custom shortcode through which we can pass custom attributes, and specifically taxonomy, post-type.</p>
<blockquote>
<blockquote>
<p>Example of what the shortcode would look like: [rscustom rsid="2" rstax="home" rspt="carousel-slide"]</p>
</blockquote>
</blockquote>
<p>Our issue: probably a dumb one, but I can't get the shortcode variables to 'pass into' the query function, my code:</p>
<pre><code>function rscustom_shortcode( $atts, $content = null ) {
// Extract variables from shortcode attributes: post type, id, taxonomy
$a = shortcode_atts( array(
'rspt' => '',
'rsid' => '',
'rstax' => '',
), $atts );
$rspt = trim($a['rspt']);
$rsid = trim($a['rsid']);
$rstax = trim($a['rstax']);
// Execute the Royal Slider Query Override
add_filter('new_royalslider_posts_slider_query_args', 'newrs_custom_query', 10, $rsid);
function newrs_custom_query($args) {
$args = array(

</code></pre>
<p>The line where I have...</p>

<p>...seems to be the bit where I'm hung up. When I have the line as... </p>

<p>...everything works wonderfully. I've looked into global variables, but just managed to confuse myself more.</p>

```
add_action( 'init', 'init_storefront_child' );

What's happen with the 'widgets\_init' hook in functions.php's child theme?
Thanks by advance.

WordPress accept security reports so as a community the more that is brought to their attention, in theory, the more secure WordPress will become. To be honest, unless your website is popular, and getting regular spam, hits, etc, you're probably not going to be worth a hackers time.

<p>Wordpress nav menu created by wp_nav_menu can highlight current menu item. How can i strip anchor from current menu item?</p>
<p>For example, we have menu:</p>
<pre><code><ul>
<li class="current-menu-item"><a href="/somelink">Home</a></li>
<li><a href="/elselink">Item</a></li>
...
</ul>

<p>Can we remove</p>
<pre><code><a href="/somelink">

<p>and leave just "Home" if it is current page?</p>

This to me is more part of your exclusions as this is the main way anyone gains access through WordPress... So not really, if you have a backup, just drop the Database, upload your backup and change the passwords - then perhaps look into additional security. A good plan is to not name the admin as admin for example (doing this on one site prevented a lot of spam attempted logins for me with people attempting to guess the password)

<p>I have a widget I want only allowed to be used with the single.php sidebar. When I referenced the codex for <a href="https://codex.wordpress.org/Function_Reference/register_sidebar" rel="nofollow noreferrer"><code>register sidebar</code></a> there isn't a way to limit widgets in the array. I've researched with "WordPress limit widget to post" but they are only plugins returned in my search results. When I change my search parameters to page to see if I can get something returned I am reference to:</p>
<ul>
<li><p><a href="https://wordpress.stackexchange.com/questions/1421/disable-specific-widgets-on-selected-pages-of-a-wordpress-website">Disable Specific Widgets on Selected Pages of a WordPress Website?</a> which is five years old and suggests plugins</p></li>

Is there a way that I can target a Widget to only be allowed for the `id` in the `register_sidebar`? I do not want to use a plugin I want to learn how to properly code it.
EDIT:
Per comments I have a custom widget. that is being called in my singles.php as `<?php get_sidebar( 'foobar' );?>`. When someone is in admin I want to limit where the widget can be applied to:

I have recently worked on [an answer](https://wordpress.stackexchange.com/a/202584/31545) where a specific widget can be removed from the array of widgets from a specific sidebar. Here we use the `sidebars_widgets` filter to remove a specific widget from all sidebars except the sidebar where it should be.
So in short, a widget that is incorrectly added to a sidebar will not show up in front end, and it will also not return true with an `is_active_sidebar()` check if that widget is the only widget added to that specific sidebar.
You can try the following code, just be sure to change the widget and sidebar values accordingly.
```
add_filter( 'sidebars_widgets', function ( $sidebars_widgets )
{
// Return our filter when we are on admin screen
if ( is_admin() )
return $sidebars_widgets;
/**
* Widget we need to target. This should be the name/id we used to register it
*
* EXAMPLE
* parent::__construct(
'widget_category_posts',
_x( 'Category Posts Widget', 'Category Posts Widget' ),
[ 'description' => __( 'Display a list of posts from a selected category.' ) ]
);
*
*/
$custom_widget = 'widget_category_posts';
// The sidebar ID we need to run the widget in
$sidebar_accept = 'sidebar-2';
// We have come this far, let us wrap this up
// See if our custom content widget exists is any sidebar, if so, get the array index
foreach ( $sidebars_widgets as $sidebars_key=>$sidebars_widget ) {
// Skip the wp_inactive_widgets set, we do not need them
if ( $sidebars_key == 'wp_inactive_widgets' )
continue;
// Only continue our operation if $sidebars_widget are not an empty array
if ( $sidebars_widget ) {
foreach ( $sidebars_widget as $k=>$v ) {
/**
* Look for our custom widget, if found, unset it from the $sidebars_widgets array
* @see stripos()
*/
if ( stripos( $v, $custom_widget ) !== false ) {
// If we are on a single page and the sidebar is $sidebar_accept, do not unset
if ( is_single() && $sidebars_key == $sidebar_accept )
continue;
unset( $sidebars_widgets[$sidebars_key][$k] );
}
} // endforeach $sidebars_widget
} // endif $sidebars_widget
} // endforeach $sidebars_widgets
return $sidebars_widgets;
});
```
In conclusion, this is just a PHP workaround which does work only for the front end, but I would urge you to still look for a proper jquery solution where a widget is only bound to a specific sidebar in the backend. As I said, the jquery solution from the link is untested and I do not know if if really works

How do I get total number of Authors on the site?
This shows summery of users on the site but I just want to get number of Authors.
```
<?php
$result = count_users();
echo 'There are ', $result['total_users'], ' total users';
foreach($result['avail_roles'] as $role => $count)
echo ', ', $count, ' are ', $role, 's';
echo '.';
?>
```
<https://codex.wordpress.org/Function_Reference/count_users>
|
You can use the [`WP_User_Query`](https://codex.wordpress.org/Class_Reference/WP_User_Query) class, like the example below. Each code line have an small description, that you understand, what we do.
```
// Get all users with role Author.
$user_query = new WP_User_Query( array( 'role' => 'Author' ) );
// Get the total number of users for the current query. I use (int) only for sanitize.
$users_count = (int) $user_query->get_total();
// Echo a string and the value
echo 'So much authors: ' . $users_count;
```
Alternative you can also use the function [`get_users()`](https://codex.wordpress.org/Function_Reference/get_users). But is only a wrapper for the query and have much more fields in the result.

<p>Sorry for this question, but I can't work out why my site name isn't showing in the browser window even though I have <code>wp_title()</code> in the <code><head></code>. </p>
<p>All I have done is used CSS to indent the text -9999px so it's off the screen but I thought that would still register as the title in the browser?</p>
<p>When I navigate through to posts, the post name appears, but the site name doesn't appear on those pages either, even though it should appear before the post.</p>
<p>I'm stumped. Any help would be greatly appreciated!</p>
<p>Thanks in advance!</p>
<hr>
<p>Following on from Will's advice I included the following code in the <code>functions.php</code>:</p>
<pre><code>function twentytwelve_wp_title( $title, $sep ) {
global $paged, $page;
if ( is_feed() )
return $title;
// Add the site name.
$title .= get_bloginfo( 'name' );

return $title;
}
add_filter( 'wp_title', 'twentytwelve_wp_title', 10, 2 );

<p>and then changed the <code><title></code> tag to the following: </p>

I'm building a theme that generates on the home template a link to the PDF attached to the post (it will be only PDF files).
I found a solution to check if the post has a PDF attached. The goal is to create a link that downloads the file, on the home (blog) template.
Here's what I currently have
```
function leoni_get_attachment() {

} else {

}
}
```
I've tried using `get_attached_file()` without success.
|
Well, there is a WP function for that.
wp\_get\_attachment\_url
It takes attachment id as argument, so you can use it like in following example:
```
echo wp_get_attachment_url( 12 );
```
This will echo url to attachment which id is 12.
You can find more info and examples on Codex page:

<p>I'm a bit confused with templates for custom post types defined as hierarchical. I've got a CPT set to hierarchical, not strictly in order to have a nested hierarchy, but so that they can be ordered by the Simple Page Ordering plugin. Here's the code:</p>
<pre><code>register_post_type(
'case_study', array(
'label' => _x( 'case studies', 'post type plural name' ),
'labels' => array(
'name' => _x( 'Case studies', 'post type general name' ),
'singular_name' => _x( 'Case study', 'post type singular name' ),
'menu_name' => _x( 'Case studies', 'admin menu' ),
'name_admin_bar' => _x( 'Case study', 'add new on admin bar' ),
'add_new' => _x( 'Add New', 'case study' ),
'add_new_item' => __( 'Add New Case study' ),
'new_item' => __( 'New Case study' ),
'edit_item' => __( 'Edit Case study' ),
'view_item' => __( 'View Case study' ),
'all_items' => __( 'All Case studies' ),
'search_items' => __( 'Search Case studies' ),
'parent_item_colon' => __( 'Parent Case studies:' ),
'not_found' => __( 'No Case studies found.' ),
'not_found_in_trash' => __( 'No Case studies found in Trash.' )
),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_nav_menus' => true,
'show_in_menu' => true,
'show_in_admin_bar' => true,
'menu_position' => 20, // Below Pages
'menu_icon' => 'dashicons-clipboard', // @link https://developer.wordpress.org/resource/dashicons/
'query_var' => false,
'rewrite' => array( 'slug' => 'case-study', 'with_front' => false ),
'capability_type' => 'case_study',
'map_meta_cap' => false,
'capabilities' => array(
'publish_posts' => 'publish_case_studies',
'edit_posts' => 'edit_case_studies',
'edit_others_posts' => 'edit_others_case_studies',
'delete_posts' => 'delete_case_studies',
'delete_others_posts' => 'delete_others_case_studies',
'read_private_posts' => 'read_private_case_studies',
'edit_post' => 'edit_case_study',
'delete_post' => 'delete_case_study',
'read_post' => 'read_case_study',
),
'has_archive' => false,
'hierarchical' => true, // Set to true to allow ordering
'supports' => array( 'title', 'editor', 'custom-fields', 'thumbnail', 'revisions', 'pilau-author' ),
'taxonomies' => array( 'topic' ),
)
);
</code></pre>
<p>By default a hierarchical CPT uses the page.php template instead of single.php - which took me a while to realise, but it makes sense.</p>
<p>However, now I want to create a template specifically for this CPT, and single-case_study.php doesn't work. Neither does page-case_study.php.</p>
<p>How do you create a template specifically for a hierarchical CPT?</p>

I'm a bit confused with templates for custom post types defined as hierarchical. I've got a CPT set to hierarchical, not strictly in order to have a nested hierarchy, but so that they can be ordered by the Simple Page Ordering plugin. Here's the code:
```
register_post_type(
'case_study', array(
'label' => _x( 'case studies', 'post type plural name' ),
'labels' => array(
'name' => _x( 'Case studies', 'post type general name' ),
'singular_name' => _x( 'Case study', 'post type singular name' ),
'menu_name' => _x( 'Case studies', 'admin menu' ),
'name_admin_bar' => _x( 'Case study', 'add new on admin bar' ),
'add_new' => _x( 'Add New', 'case study' ),
'add_new_item' => __( 'Add New Case study' ),
'new_item' => __( 'New Case study' ),
'edit_item' => __( 'Edit Case study' ),
'view_item' => __( 'View Case study' ),
'all_items' => __( 'All Case studies' ),
'search_items' => __( 'Search Case studies' ),
'parent_item_colon' => __( 'Parent Case studies:' ),
'not_found' => __( 'No Case studies found.' ),
'not_found_in_trash' => __( 'No Case studies found in Trash.' )
),
'public' => true,
'publicly_queryable' => true,
'show_ui' => true,
'show_in_nav_menus' => true,
'show_in_menu' => true,
'show_in_admin_bar' => true,
'menu_position' => 20, // Below Pages
'menu_icon' => 'dashicons-clipboard', // @link https://developer.wordpress.org/resource/dashicons/
'query_var' => false,
'rewrite' => array( 'slug' => 'case-study', 'with_front' => false ),
'capability_type' => 'case_study',
'map_meta_cap' => false,
'capabilities' => array(
'publish_posts' => 'publish_case_studies',
'edit_posts' => 'edit_case_studies',
'edit_others_posts' => 'edit_others_case_studies',
'delete_posts' => 'delete_case_studies',
'delete_others_posts' => 'delete_others_case_studies',
'read_private_posts' => 'read_private_case_studies',
'edit_post' => 'edit_case_study',
'delete_post' => 'delete_case_study',
'read_post' => 'read_case_study',
),
'has_archive' => false,
'hierarchical' => true, // Set to true to allow ordering
'supports' => array( 'title', 'editor', 'custom-fields', 'thumbnail', 'revisions', 'pilau-author' ),
'taxonomies' => array( 'topic' ),
)
);
```
By default a hierarchical CPT uses the page.php template instead of single.php - which took me a while to realise, but it makes sense.
However, now I want to create a template specifically for this CPT, and single-case\_study.php doesn't work. Neither does page-case\_study.php.
How do you create a template specifically for a hierarchical CPT?

Old question but maybe it helps someone else:
You could do something like this in page.php:
```
$postType = get_post_type();
if($postType == 'case_study'){
include('single-case_study.php');
} else{
// Do your page.php stuff
```

<p>Hi. I don't know ajax programming. I know HTML, CSS, little bit of php(so much that I am editing and customizing all the default themes, and learning along the way). </p>
<p>I have attached the UI of the page which my designer has designed. Now I am making this in wordpress. I have assigned the left menu as the category menu, so it has categories of all the posts.</p>
<p>I can create different templates for trending posts and fresh posts. So basically I will have then 3 templates for the category page (default, trending and fresh)</p>
<p>What I would like to know is how to display a separate menu for trending, fresh and default. Eg if the user is on default page (home page), then the category menu on the left will use the default template, when he is on the trending page, the category menu on the left will use the trending template and so on. Is there a simple way to do this ? Can I do this with ajax too ? </p>
<p>The theme is twenty fourteen child ..</p>

Either include <code>'page-attributes'</code> in the <code>supports</code> array or use the <code>simple_page_ordering_is_sortable</code> filter, then you can click 'Sort by Order' on the posts admin listing page and drag-and-drop.</p>\n"

<p>guys! I'm pretty sure this will be a piece of cake for y`all, but I'm trying to add pagination to my loop. I've tried some codes that were available around, and got to paginate it, but pages 2, 3, etc had the same content from page 1. What's the best solution for what I have at the moment?</p>
<pre><code><?php
$recentPosts = new WP_Query();
$recentPosts->query('showposts=5');
?>
<?php while ($recentPosts->have_posts()) : $recentPosts->the_post(); ?>
<article>
</article>
<?php endwhile; ?>
</code></pre>
<p>Thanks in advance.</p>

Likely this is happening because you are using a custom page template. Try the following. I've commented the steps along the way. Hope it helps.
```
<?php
//get the current page
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
//pagination fixes prior to loop
$temp = $query;
$query = null;
//custom loop using WP_Query
$query = new WP_Query( array(
'post_status' => 'publish',
'orderby' => 'date',
'order' => 'ASC'
) );
//set our query's pagination to $paged
$query -> query('post_type=post&posts_per_page=5'.'&paged='.$paged);
if ( $query->have_posts() ) :
while ( $query->have_posts() ) : $query->the_post();
?>
<li>
<?php if ( has_post_thumbnail()) : ?>
<?php the_post_thumbnail();?>
<?php endif; ?>
<div class="someclass" >
<h2><?php the_title(); ?></h2>
<?php the_content(); ?>
</div>
</li>
<?php endwhile;?>
<?php //pass in the max_num_pages, which is total pages ?>
<div class="pagenav">
<div class="alignleft"><?php previous_posts_link('Previous', $query->max_num_pages) ?></div>
<div class="alignright"><?php next_posts_link('Next', $query->max_num_pages) ?></div>
</div>
<?php endif; ?>
<?php //reset the following that was set above prior to loop
$query = null; $query = $temp; ?>

You cad add it via `functions.php` with a hook, instead of inside the loop (you don't really want to add a loop to header.php):
```
function add_author_meta() {
if (is_single()){
global $post;
$author = get_the_author_meta('user_nicename', $post->post_author);
echo "<meta name=\"author\" content=\"$author\">";
}
}
add_action( 'wp_enqueue_scripts', 'add_author_meta' );
```
