<p>This works great, however on the shop base page it is not showing the pages featured image. However it is showing the last product image. This is basically an archive page, but outside of WordPress I guess. </p>
<p><strong>How can I get the featured image of the base shop page to show instead of the last product image?</strong></p>

This works great, however on the shop base page it is not showing the pages featured image. However it is showing the last product image. This is basically an archive page, but outside of WordPress I guess.
**How can I get the featured image of the base shop page to show instead of the last product image?** | I found it at last!
Using the browser debugger, I found that there was a "editor.wp" which was undefined (in the complete version of the js file).
Then I understood that the "wordpress" plugin was not used in the editor.
When calling the function wp\_editor, I was setting a list of plugin : paste, wplink, textcolor.
It was working until a specific WordPress update.
I just had to add the "wordpress" plugin in the list, and now it's working. |

| What's the difference beetween
`define( 'WP_MEMORY_LIMIT', '96M' );`
and
`define( 'WP_MAX_MEMORY_LIMIT', '256M' );`
In my host I have this
```
define( 'WP_MEMORY_LIMIT', '786M' );
define( 'WP_MAX_MEMORY_LIMIT', '512M' );
```
is this correct, should the `WP_MAX_MEMORY_LIMIT` be higher ? | WordPress tells us:
>
> the WP\_MEMORY\_LIMIT option allows you to specify the maximum amount of
> memory that can be consumed by PHP. This setting may be necessary in
> the event you receive a message such as "Allowed memory size of xxxxxx
> bytes exhausted".

Or as the [PHP docs put it](http://php.net/manual/en/ini.core.php#ini.memory-limit)
>
> [A memory limit] helps prevent poorly written scripts for eating up all available
> memory on a server.
>
>
>
The [WordPress Codex](https://codex.wordpress.org/Editing_wp-config.php#Increasing_memory_allocated_to_PHP) also says this about these constants:
>
> This setting [`WP_MEMORY_LIMIT`] increases PHP Memory only for WordPress, not other

>
>
>
And this about the `WP_MAX_MEMORY_LIMIT` specifically:
>
> Administration tasks require much [more] memory than [a] usual operation. When in
> the administration area, the memory can be increased or decreased from

>
So `WP_MEMORY_LIMIT` is the limit and `WP_MAX_MEMORY_LIMIT`, if set, will override the former in the admin.
Now when you ask "is this correct", there is no way for us to tell you definitively.
You may want to raise those limits if your site is growing in visitors and or active plugins but if you are not experiencing any issues I would say you are fine for now.
If you choose to up the limits I have outlined the different methods to increase PHP memory in [this answer](https://wordpress.stackexchange.com/a/268505/119673). Note the last part about your host potentially limiting this value. |

[](https://i.stack.imgur.com/1xkvk.png)
```
$args = array(
'post_type' => 'customer'
);
$the_query = new WP_Query( $args );
```
Im trying to display content from post `projects` (about customer).
Page `single-customer.php` display content from `customers`, but I need post from `projects`.
[](https://i.stack.imgur.com/o2Pl5.png)
How get this post content? Its possible?
**UPD**
code in `single-customer.php`:
```
`<div class="page-head text-center">
<div class="container">
<h1 class="page-head_title"><?php the_title(); ?></h1>
<p><?php the_subtitle(); ?></p>
</div>
</div>
<?php
// This is for projects posts
$args = array(
'post_type' => 'project'
);
$the_query = new WP_Query( $args );
?>
<?php if ($the_query->have_posts()) : ?>
<?php while ($the_query->have_posts()) : $the_query->the_post(); ?>
// loop here
<?php the_title(); ?>
<?php the_content(); ?>
<?php endwhile;
wp_reset_postdata();
else : ?>
<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>`
```
**UPD**
if i use this code `<?php acf_form(); ?>` its display content which i need, but its display all textarea and inputs of wp-admin panel. if i use `<?php the_field('project-sections'); ?>` - its display `Array, Array, Array, Array` | i found solution:
```
<?php if( have_rows('project-sections') ): ?>
<?php $i = 0; ?>
<?php while( have_rows('project-sections') ): the_row(); ?>
<section class="<?php if ($i % 2 == 0) : ?>bg-gray<?php else: ?>bg-white<?php endif; ?>">
<div class="container">
<h2 class="page-head_sub-title"><?php the_sub_field('project-sections-title'); ?></h2>
<?php the_sub_field('project-sections-description'); ?>
</div>
</section>
<?php $i++; ?>
<?php endwhile; ?>
<?php endif; ?>
```
Need to use
`<?php the_sub_field('name-sub-field'); ?>`
inside
`<?php while( have_rows('name-field') ): the_row(); ?>` |

270,366 | <p>I am an experienced PHP developer, but new to WordPress. I created a site and added some custom JavaScript, CSS, and a number of shortcodes. My CSS was just added to style.css (The default when I clicked on Appearance->Editor in the sidebar) and the hooks to my JavaScript as well as my shortcodes were in my theme's functions.php file.</p>
<p>Naturally, the theme updated and all my changes were wiped. Thankfully I had backups saved, so I was able to restore my custom code, but I really want all my custom code to be completely independent of the theme. What's the proper way to handle shortcodes, css, and script/style enqueing so that theme changes won't remove them?</p>
<p>I found a number of blogs recommending using child themes, but as I understand it that's not truly theme agnostic, for lack of a better term. I want my shortcodes and JS libraries to remain in place no matter if the theme updates, wordpress updates, or I change themes completely.</p>
<p>I also made a small update to my theme's header.php file (I wanted the ability to add a quote to my site, above the menu items, and reposition where the site logo was displayed) I'm imagining this will be more difficult to maintain since, unlike CSS and shortcodes, it is actually changing the content, not adding to it. Is there any way to protect/maintain changes to a theme's header.php as well?</p>

| I am an experienced PHP developer, but new to WordPress. I created a site and added some custom JavaScript, CSS, and a number of shortcodes. My CSS was just added to style.css (The default when I clicked on Appearance->Editor in the sidebar) and the hooks to my JavaScript as well as my shortcodes were in my theme's functions.php file.
Naturally, the theme updated and all my changes were wiped. Thankfully I had backups saved, so I was able to restore my custom code, but I really want all my custom code to be completely independent of the theme. What's the proper way to handle shortcodes, css, and script/style enqueing so that theme changes won't remove them?
I found a number of blogs recommending using child themes, but as I understand it that's not truly theme agnostic, for lack of a better term. I want my shortcodes and JS libraries to remain in place no matter if the theme updates, wordpress updates, or I change themes completely.
I also made a small update to my theme's header.php file (I wanted the ability to add a quote to my site, above the menu items, and reposition where the site logo was displayed) I'm imagining this will be more difficult to maintain since, unlike CSS and shortcodes, it is actually changing the content, not adding to it. Is there any way to protect/maintain changes to a theme's header.php as well? | i found solution:
```
<?php if( have_rows('project-sections') ): ?>
<?php $i = 0; ?>
<?php while( have_rows('project-sections') ): the_row(); ?>
<section class="<?php if ($i % 2 == 0) : ?>bg-gray<?php else: ?>bg-white<?php endif; ?>">
<div class="container">
<h2 class="page-head_sub-title"><?php the_sub_field('project-sections-title'); ?></h2>
<?php the_sub_field('project-sections-description'); ?>
</div>
</section>
<?php $i++; ?>
<?php endwhile; ?>
<?php endif; ?>
```

`<?php the_sub_field('name-sub-field'); ?>`
inside
`<?php while( have_rows('name-field') ): the_row(); ?>` |

**Update:**
The same using filter as suggested:
```
add_filter('human_time_diff', 'new_human_time_diff', 10, 2);
function new_human_time_diff($from, $to) {

**EDIT: Jack Johansson's SOLUTION**
Created a php file: `page-custom.php` as below:
```
<?php
/**
* Template Name: My Custom Template
*/
if (is_page_template( 'page-custom.php' ) && isset($_REQUEST['cat'])){
...
}
?>
```
Created a page with `ID: 281` which uses `page-custom.php` template.
My `functions.php`:
```
function my_rewrite_tag() {
add_rewrite_tag('%cat%', '([^&]+)');
}
function my_rewrite_rule() {
add_rewrite_rule('^categories/([^/]*)/?','index.php?page_id=281&cat=$matches[1]','top');
}
add_action('init', 'my_rewrite_tag', 10, 0);
add_action('init', 'my_rewrite_rule', 10, 0);
```
Now when I navigate to an example url like the one below
>
> <http://localhost/mydomain/categories/123/>
>
>
>
Problem is `$_REQUEST['cat']` is empty so it never enters to the condition inside `page-custom.php` | Why don't we create our own template file, and do our stuff there? Here's what I'm going to do:
1. Create a custom page template
2. Call the required plugin's functions inside the page
3. Redirect the plugins URLs to the page
4. Get the query var and process the request
---
- The page template
--------------------
Let's create a simple custom page template. We call it `page-custom.php`. We will use this page to interact with our plugin.
```
<?php
/**
* Template Name: My Custom Template
*/
// Our function to get the data
if (function_exists('sample_function')) sample_function();
?>
```
We also create a page in the back-end, its slug is `/my-custom-page/` and its ID is `123`.
- The rewrite rules
-------------------
Now let's check if we are on that page and redirect the data to it.
```
function my_rewrite_tag() {
add_rewrite_tag('%cat%', '([^&]+)');
}
function wallpaperinho_subcat_rewrite_rule() {
add_rewrite_rule('^categories/([^/]*)/?','index.php?page_id=123&cat=$matches[1]','top');
}
add_action('init', 'my_rewrite_tag', 10, 0);
add_action('init', 'my_rewrite_rule', 10, 0);
```
What does this piece of code do? It checks if we are visiting `/categories/321/` and redirects it to our page. Now we have the data we need. Let's check the template.
- The conditional for template
------------------------------
We check if we are on `page-custom.php` and return our data to the page.
```
if (is_page_template( 'templates/about.php' ) && isset($_REQUEST['cat'])){
function sample_function() {
$c = $_REQUEST['cat'];
// We have the c value, call the internal plugin's functions and return its value to the page
return $data;
}
}
```
This serves as an example, to create our own template and use the redirects to make it look like whatever we want. It can and needs to be changed to fit your needs. |

| I've got a shortcode working to return tags that are used on a particular post but can't figure out how to return the description with it.
```
function returnpost_tags(){
return get_the_tag_list('',', ',' ');
}
add_shortcode('post-tags', 'returnpost_tags');
```
I tried
```
return get_the_tag_list('',', ',' $description');
```
but obviously something not right
as a bonus I'd like to alternatively as a separate function return the list with description but without the links to the tags archive which is the normal behavior
thanks for the help | This is how you can loop with custom taxonomy.
```
function returnpost_tags(){
// get tags by post ID
$post_ID = get_the_ID();
// here, you can add any custom tag
$terms = get_the_terms( $post_ID , 'post_tag' );
echo '<ul>';
foreach ( $terms as $term ) {
// The $term is an object, so we don't need to specify the $taxonomy.
$term_link = get_term_link( $term );
$term_ID = $term->term_id;
// If there was an error, continue to the next term.
if ( is_wp_error( $term_link ) ) {
continue;
}
echo '<li><a href="' . esc_url( $term_link ) . '">' . $term->name . '</a></li>';
echo term_description($term_ID);
// another option
// echo '<p>' . $term->description . '</p>';
}
echo '</ul>';
}
add_shortcode('post-tags', 'returnpost_tags');
```
You can replace **post\_tag** with your custom taxonomy
```
$terms = get_terms( 'post_tag' );
```
To get tag's description, you can use one of the below method.
```
echo $term->description;
```
or
```
echo term_description($term->term_id);

``` | It is necessary to set an `alt` value for all of your images, in case a browser can not load the image or the visitor is using screen reader.
You have two options. Either use the featured image's caption (which can some times be blank) or use the post's title as `alt`.
You can get the caption by using [`get_post_meta()`](https://developer.wordpress.org/reference/functions/get_post_meta/). Using it is as simple as this:
```
$alt = get_post_meta ( $image_id, '_wp_attachment_image_alt', true );
echo '<img alt="' . esc_html ( $alt ) . '" src="URL HERE" />';
```
It should be used in the loop though, or be passed the `$post` object or ID.
The alternative method is to use post's title as `alt` text. To do so, you can use:
```
echo '<img alt="' . esc_html ( get_the_title() ) . '" src="URL HERE" />';
```
You can set up a conditional and check if the thumbnail has a caption, and use it instead of post title, if available:
```
if ( $alt = get_the_post_thumbnail_caption() ) {
// Nothing to do here
} else {
$alt = get_the_title();
}
echo '<img alt="' . esc_html ( $alt ) . '" src="URL HERE"/>
```
UPDATE
------
If you wish to add the `alt` attribute directly to `get_post_thumbnail()`, you can pass it as an array to the function:
```
the_post_thumbnail( 'thumbnail', [ 'alt' => esc_html ( get_the_title() ) ] );

| I want to convert PHP website into WordPress. So, I want to know there are a .html at end of the URL when WordPress permalink is not ended with .html. So, is it affected to SEO? | If you currently have `/path/to/site.html` and change it to `/path/to/site`, this will affect SEO, as search engines think they know the url (the former).
However, there are solutions to this. You can either keep the `.html` at the end of the URL (there should be no problem to use a WordPress permalink with .html in the end), or if you want to clean up your URLs, you need to redirect from one to the other ([use 301 redirects](http://www.morevisibility.com/blogs/seo/when-and-why-to-use-301-or-302-redirects.html)).
There is extensive material on how redirects work ([like this](https://stackoverflow.com/questions/20563772/reference-mod-rewrite-url-rewriting-and-pretty-links-explained)), if you only want the .html to disappear (and rest of the URL stays the same), something like this could already work in an .htaccess
```
RewriteRule ^(*.)\.html$ $1 [R=301,QSA,L]
```
Otherwise, you'd need a more complex structure which depends on your specific current situation. |

``` | The best way to sanitize text fields within WordPress is to use [`sanitize_text_field()`](https://developer.wordpress.org/reference/functions/sanitize_text_field/) function:
```
$data = sanitize_text_field( $_POST['key'] );
```
Additionally, if you register the meta field properly width [`register_meta()`](https://developer.wordpress.org/reference/functions/register_meta/) function, you can define the sanitize callback and the expected data type as well. For example:
```
add_action( 'init', 'cyb_register_meta_fields' );
function cyb_register_meta_fields() {
$args = array(
'sanitize_callback' => 'sanitize_text_field'
);
register_meta( 'post', 'key', $args );
}
```
By using `register_meta()` you don't need to sanitize the meta field every time you upadate or create it, just use `upadate_post_meta()`/`add_post_meta()` and the sanitize callback will be used automatically. So, if your meta field is an array, it could be something like this:
```
add_action( 'init', 'cyb_register_meta_fields' );
function cyb_register_meta_fields() {
$args = array(
'sanitize_callback' => 'sanitize_price_field'
);
register_meta( 'post', 'price_data', $args );
}
function sanitize_price_field( $meta_value ) {
foreach ( (array) $meta_value as $k => $v ) {
if ( is_array( $v ) ) {
$meta_value[$k] = sanitize_price_field( $v );
} else {
$meta_value[$k] = sanitize_text_field( $v );
}
}
return $meta_value;
}

```
I loaded these scripts in shortcode to load scripts and style when only shortcode is used or called.
```
function my_shortcodes_init()
{
function my_shortcode($atts = [], $content = null)
{
//default portfolio value
$id = 1;
wp_enqueue_style('my-css');
wp_enqueue_script('my-jquery-min');
wp_enqueue_script('my-script-min');
wp_enqueue_script('my-script');
wp_enqueue_script('my-lightbox-script');
if (isset($atts["id"])) {
$id = $atts["id"];
}
require MY_PLUGIN_DIR.'views/isotope.php';
}
add_shortcode('MY_GALLERY', 'my_shortcode');
}
add_action('init', 'my_shortcodes_init');
``` | This happens because of the order of execution of your WordPress page. In your code it goes like this:
1. At `init`, which is early in the generation process of the page, you are registering the scripts. That is, you are telling WP that you want to use these later on. No html is generated.
2. At `init` you are also registering a shortcode. This means that you are defining a function that will be triggered once the shortcode has been encountered. No html is generated.
3. WP then goes on generating the html. First the head of the page, menus and so on, until it comes to the post content.
4. In the post content it finds the shortcode and starts executing the function `my_shortcode` you have defined. Inside this function it finds `wp_enqueue_script`. At this point the html of the head already has been generated. So it has no choice but placing the html with the scripts in the footer of the page.
If you want the scripts in the head, you must make sure `wp_enqueue_scripts` is triggered at `init`. Of course, this means they will also be enqueued when there is no shortcode in the content. |

270,886 | <p>I have a caching plugin (WP Rocket) so I am aware of the issues with wp-cron and scheduled posts. So, I disabled <strong>wp-cron</strong> and then set up a system cron. Now, I noticed that when a post is scheduled it's not set to <strong>HH:MM:00</strong> but has some number greater than <strong>0</strong> seconds. So, I set the system cron to run wp-cron at every 5 minutes and 35 minutes past the hour. And still I get missed schedule on posts. I know it runs as I have the output logged which shows a <strong>200</strong> return code plus I see my cache files with timestamps at 5 minutes and 35 minutes past the hour.</p>
<pre><code>define('DISABLE_WP_CRON', true);
</code></pre>
<p>Cron entry (I x'd out my user name. I also have one for 35 minutes with output to wget35.log):</p>
<pre><code>5 * * * * wget -o /home/xxxxx/logs/wget5.log https://www.jennystampsup.com/wp-cron.php?doing_wp_cron 2>/home/xxxxx/logs/wget5.err
</code></pre>
<h2>Update</h2>
<p>Using WP-Control I see that the <code>check_and_publish_future_post</code> event for the post remains as an event after <code>wget</code> runs. I can run it manually from WP-Control and the <code>post_status</code> went to <strong>publish</strong>. If I run <code>wget</code> twice it works. The first <code>wget</code> took one second. The second took 17 seconds, but after it ran the <code>check_and_publish_future_post</code> fired. I will create a script that runs <code>wget</code> several times with some sleep statements and that should do it.</p>
<h2>Update 6/27</h2>
<p>So, posts on my site are scheduled for <strong>7:00:XX</strong>. So, I wrote a script that hits <code>wp-cron.php</code> 10 times, sleeping two seconds in between each hit, and had it kick off in my system cron at <strong>7:01</strong>. And still <code>publish_future_post</code> did not fire. I looked at the WP Cron schedule prior to my script firing and there were 8 other cron events waiting to fire. They all fired. So, I went to Cloud9 and hit <code>wp-cron.php</code> from there. This caused the <code>publish_future_post</code> to fire. The only variables there are it is a different ip and time zone. Those should make no difference as far as I know. This is very puzzling.</p>

| The idea is to immediately show the post matching the search term.
The search term will be alphanumeric and unique for each post (set as title).
It could override search in content (for performance), I just need the title.
The search will be provided through a barcode reader, so it will be unique and precise.
I'm trying to immediately show the post, not the search results page, but I can't figure how. | Here's a solution that I came up with that uses a hidden field on the search form which we will later check in our filters to modify WP's default search/redirect behavior.
This is the search form I used. Note the addition of the hidden field `barcode-reader` with a value of `1`. I added the search form to a page template for testing and demonstration purposes.
```
<form role="search" method="get" class="search-form" action="<?php echo esc_attr( home_url( '/' ) ); ?>">
<label>
<span class="screen-reader-text"><?php echo _x( 'Search for:', 'screen reader search label', 'textdomain' ); ?></span>
<div class="input-group">
<input type="search" class="search-field input-group-field" placeholder="<?php echo esc_attr_x( 'Search...', 'search placeholder', 'textdomain' ); ?>" value="<?php echo get_search_query(); ?>" name="s" title="<?php echo esc_attr_x( 'Search for:', 'textdomain' ); ?>" />
<input type="hidden" value="1" name="barcode-reader" />
<div class="input-group-button">
<button type="submit" class="search-submit button" value="<?php echo esc_attr_x( 'Search', 'search button', 'textdomain' ); ?>">Search</button>
</div>
</div>
</label>
</form>
```
(*It's not clear from the original post, but from the research I've done, it should be possible for the barcode reader to send a parameter via `$_GET` which could be used instead of the hidden field I've used for testing.)*
Here, we will check if this search is being performed by the barcode scanner using the helper function `wpse_is_barcode_search()`. The helper function is used so that we don't have to duplicate the logic across the multiple hooks that are used in this implementation.
If we are doing a search using the scanner, we wire up our `posts_search` filter and do some modifications to the `WP_Query` instance before the query is performed.
```
/**
* Wire up our posts_search filter and change the $query.
*
* @param WP_Query $query The WP_Query instance (passed by reference).
*/
add_action( 'pre_get_posts', 'wpse_barcode_search_pre_get_posts' );
function wpse_barcode_search_pre_get_posts( $query ) {
// Bail if this search is not performed by the barcode scanner.
if ( ! wpse_is_barcode_search( $query ) ) {
return;
}
// Wire up the filter to modify the search SQL.
add_filter( 'posts_search', 'wpse_barcode_posts_search', 10, 2 );
// Set posts_per_page to one since we're only looking for an exact match anyway.
$query->set( 'posts_per_page', 1 );
// (suggestion) Limit search to a particular post type.
// $query->set( 'post_type', array( 'product', ) );
}
```
Here is the filter that actually modifies the search SQL. Since we only want this to fire once, the filter is immediately unooked.
```
/**
* Modify search query so that the search term looks for an exact
* match with the post title.
*
* @param string $search Search SQL for WHERE clause.
* @param WP_Query $wp_query The current WP_Query object.
*/
function wpse_barcode_posts_search( $search, $wp_query ) {
// We only want the search filter to fire once, so unhook it.
remove_filter( 'posts_search', 'wpse_barcode_posts_search', 10, 2 );
// Change the search SQL so that it checks if the search is equal to the post title.
$search = " AND (wp_posts.post_title = '" . esc_sql( $wp_query->query_vars['s'] ) . "')";
return $search;
}
```
This code redirects the user to the permalink of our found post rather than the search results page.
```
/**
* Redirect to the permalink of the searched item if it was found using
* the barcode search.
*
* @link https://wordpress.stackexchange.com/a/128578/2807
*/
add_action( 'template_redirect', 'wpse_barcode_search_success_redirect' );
function wpse_barcode_search_success_redirect() {
global $wp_query;
if ( ! wpse_is_barcode_search( $wp_query ) ) {
return;
}
// If we have a post, redirect to it.
if ( '1' === $wp_query->found_posts ) {
wp_redirect( get_permalink( $wp_query->posts['0']->ID ) );
exit;
}
}
```
Finally, here is the helper function used to determine if we are performing a search using the barcode scanner. This should be modified so that it works with the scanner used ( particularly, the check using `$_REQUEST['barcode-reader']` ).
```
/**
* Helper function used to determine if a search is performed using
* the barcode scanner.
*
* @uses array $_REQUEST
* @param object $query
* @return bool
*/
function wpse_is_barcode_search( $query ) {
// Bail if $query is not an instance of WP_Query.
if ( ! ( $query instanceof WP_Query ) ) {
return false;
}
// Bail if this is the admin area.
if ( $query->is_admin() ) {
return false;
}
// Bail if this is not the search page or main query.
if ( ! $query->is_search() || ! $query->is_main_query() ) {
return false;
}
// Bail if this is not our special barcode search.
if ( ! isset( $_REQUEST['barcode-reader'] ) || '1' !== $_REQUEST['barcode-reader'] ) {
return false;
}
return true;
}

| I'm learning about coding plugin.
I trying to create a form in plugin page and it can send mail.
This is my code, but it doesn't work(I did not receive email and did not show any error).
```
add_action('admin_menu', 'add_contact_us_page');
function add_contact_us_page() {
add_menu_page(
__( 'Contact Us', 'textdomain' ),
__( 'Contact Us','textdomain' ),

E-mail:<br>
<input type="text" name="email"><br>
Message:<br>
<input type="text" name="message" size="50"><br><br>

</form>
<?php
}
if ( isset($_POST["submit"])) {
do_action('my_phpmailer_example');
}
add_action( 'phpmailer_init', 'my_phpmailer_example' );

$phpmailer->isSMTP();
$phpmailer->Host = 'smtp.sendgrid.net';

$phpmailer->Body = "<i>Mail body in HTML</i>";
$phpmailer->AltBody = "This is the plain text version of the email content";
$phpmailer->AddAddress("[email protected]", "name");

```
Please help, thanks! | I suggest you first of all to separate code from markup, especially dividing your executing file like the function `support_form()`.
Next, please try to send email without form with hard coded message. It is possible you have mis-configuration on your server if you developing on local machine.
And finally, you should fill `action` attribute for `<form>` tag. And that must refer to the executable script. Otherwise it tries to execute you homepage where this code is absent. If you are not planning to separate your markup and code I suppose you should link your action to the file that contains this script. When that happens, your code
```
if ( isset($_POST["submit"])) {
do_action('my_phpmailer_example');
}
```
will execute. |

| If I update WordPress my custom data will be deleted from the wp\_users table?

The only way to be sure is to test it, but for future reference:
**Never modify the scheme of WordPress Tables**
If you need to add additional information about something, WordPress provides meta, user meta, site meta, post meta, comment meta. You may know these as custom fields.
For example:
```
$value = get_user_meta( $user_id, 'example', true );
update_user_meta( $user_id, 'example', 'newvalue' );
$all_meta = get_user_meta( $user_id );
```
Adding columns manually to tables also bypasses the caching layer slowing things down, encourages writing manual SQL statements ( you could have used the `WP_User_Query` class! ), and stops the information being imported/exported ( custom post types get put in content exports, custom tables don't )
I recommend writing a small WP CLI command to fetch each user and store these columns as user meta instead |

``` | It is possible, especially if the update includes changes to the user table. The only way to be sure is to test it, but for future reference:
**Never modify the scheme of WordPress Tables**
If you need to add additional information about something, WordPress provides meta, user meta, site meta, post meta, comment meta. You may know these as custom fields.
For example:
```
$value = get_user_meta( $user_id, 'example', true );
update_user_meta( $user_id, 'example', 'newvalue' );
$all_meta = get_user_meta( $user_id );
```
Adding columns manually to tables also bypasses the caching layer slowing things down, encourages writing manual SQL statements ( you could have used the `WP_User_Query` class! ), and stops the information being imported/exported ( custom post types get put in content exports, custom tables don't )
I recommend writing a small WP CLI command to fetch each user and store these columns as user meta instead |

Thanks | You're using relative URLs that will always look inside the current URL structure. You either need to add a slash before wp-content, or put in the full URL to the resources.
So for example: `src: url('/wp-content/themes/mytheme/fonts/font.ttf');`
or `src: url('http://example.com/wp-content/themes/mytheme/fonts/font.ttf');` |

| What I want to accomplish
=========================
I need an aside to pull the last 5 posts from a specific set of 5 categories.
Not the latest of each, not the last 5 of each, but the last 5 total posts from the 5 categories.
The category IDs are: 89,90,91,92,93
Background
==========
I have 5 different category pages, so this has been making it trickier. Each of these uses an include for the aside. I am writing that logic in that include.
PHP
---
```
<?php
if ( in_category( 92, $post_id ) ) : ?>
$bfaCat = 'bfa-cat-ba';
<?php endif; ?>
```
Then I have to loop through. Not applying anything if the post is not in any of the categories. But if the posts are of that category then add a variable (as `$bfaCat`) with the following class (on right) applied if it has the following category id (on left)
```
89 - bfa-cat-bl
90 - bfa-cat-fs
91 - bfa-cat-s1
92 - bfa-cat-ba
93 - bfa-cat-ea
```
HTML - ATTEMPT 1 - in template
------------------------------
```
<div class="bfa-category <?=$bfaCat;?>">
<?php the_category(); ?>
</div>
```
HTML - desired output example
-----------------------------
```
<div class="bfa-category bfa-cat-bl">
<?php the_category(); ?>
</div>
```
HTML - ATTEMPT 2 - Would this be better if modified?
----------------------------------------------------
I know this is sloppy but I also tried it inline but it just applied this class to everything
```
<div class="bfa-category <?php if (get_category('91')) echo 'bfa-cat-s1'; ?>">
<?php the_category(); ?>
</div>
```
So it seems like the class is being echoed into everything. | `get_category('91')` is always going to return an object of category ID 91's data. This means your if statement is always going to return as true. You need to get the current iterated posts assigned category ID and then check if it is 91.
```
<!-- Return objects of current iterated posts associated categories -->
$categories = get_the_category();
<!-- Get current iterated posts assigned category ID from $categories object. The [0] is because a post can be assigned to multiple categories.
In your example you are probably only assigning one category per post, so you just need to grab the ID of the first category in the returned object. -->
$category_id = $categories[0]->cat_ID;
<!-- Check if current iterated assigned posts category ID is equal to 91 -->
<div class="bfa-category <?php if ($category_id == 91) echo 'bfa-cat-s1'; ?>">
<?php the_category(); ?>
</div>

But in that case I had a JSON-LD file already prepared for me. In this particular case I can't figure out how to prepare that file. | The `<header>` elements are usually echoed directly by the theme. So without any hook or filter to change them. In that case, there is no way to change those elements with a function. Check your theme.
You could, of course, use javascript to place you attributes, but that would happen on the user end. Search engines would not see it. Since schema.org attributes are meant for search engines that is pretty useless.
What you could try is [buffering the whole page](http://php.net/manual/en/ref.outcontrol.php) and do a search and replace right before the page is completed. This is likely to run you into serious difficulties, but theoretically it's possible.
So, your best course of action is build a child theme and replace the part where the `<header>` tags are generated with your version. You would have to make a child theme anyway if you were going into the direction of a custom function as you suggest. |

| I know how to use shortcodes, even making them but what I need to understand is that a shortcode is a plain text stored in database as a post content, So how a plain text like this can be converted into dynamic.
What I want to know is how an `x` text can be handled before the server send it to the browser to behave deffirently? | When using `the_content()`, WordPress will run several filters to process the text coming from the editor. These filters process the content before it is sent to the browser. `do_shortcode` is the filter that handles shortcodes.
From `/wp-includes/default-filters.php`:
```
// Shortcodes
add_filter( 'the_content', 'do_shortcode', 11 ); // AFTER wpautop()
```
`do_shortcode()` is used to search content for shortcodes and filter the shortcodes through their hooks.
You can apply the `do_shortcode` filter to any string. For example, if you have a meta box with a text area and you would like to allow users to enter shortcodes in the text area, you could wire up the `do_shortcode` filter to handle that.
**A shortcode example:**
```
[my-shortcode param1=something param2=value]Text...[/my-shortcode]
```
When WordPress finds this shortcode in the content, it will run the function associated with the shortcode tag `my-shortcode`.
```
/**
* An example shortcode.
*
* @param array $atts
* @param string $content
* @param string $tag Shortcode tag
* @return string
*/
add_shortcode( 'my-shortcode', 'wpse_example_shortcode' );
function wpse_example_shortcode( $atts, $content = '', $tag ) {
$a = shortcode_atts( [
'param1' => false,
'param2' => false,
], $atts );
// code...
return $content . '!!!';
}
```
In this case, WordPress will run the function `wpse_example_shortcode()` passing `$atts` (parameters and their values, e.g. param1, param2), `$content` (*Text...*), and `$tag` (the shortcode tag used, `my-shortcode`).
Valid shortcodes (including their parameters and content) will be replaced with the output of the callback function that they are associated with. Invalid shortcodes will be output just as they were entered in the back end. |
271,195 | <p>I have a <a href="https://developer.wordpress.org/reference/functions/add_image_size/" rel="nofollow noreferrer">custom image size</a> <code>hello-image</code>:</p>

Finally, I started seeing this problem in a recent WordPress update, so it may be a bug in core, as opposed to an issue in my code.
**Edit**: Read the [update](https://wordpress.stackexchange.com/questions/271195/setting-jpeg-compression-for-custom-image-sizes-doesnt-work-in-specific-cases#comment402886_271261). | *Some suggestions:*
If you want to try out the *Image Editor API* you can try to replace
```
imagejpeg( $resource, $image, 35 );
```
with:
```
$editor = wp_get_image_editor( $image );
if ( ! is_wp_error( $editor ) )
{
$editor->set_quality( 35 );
$editor->save( $image );
}
unset( $editor );
```
Also try to test e.g. these parts:
```
$resource = imagecreatefromjpeg( $image );
if( false !== $resource )
{
imagejpeg( $resource, $image, 35 );
imagedestroy( $resource );
}
```
in a standalone PHP script, to make sure it's not a PHP or GD related issue.
PS: [Here's a different approach](https://wordpress.stackexchange.com/questions/163844/create-image-formats-with-different-qualities-when-uploading/165241#165241) where we try to modify the image quality **before** the image size is generated.
**Testing the plugin**
Let's check the plugin from the main question.
Test install
* WordPress version 4.9-alpha-40917
* PHP 7.0.19
[](https://i.stack.imgur.com/T7rb5.jpg)
[](https://i.stack.imgur.com/mzBEk.jpg)
Here's the generated `hello-image` (670x300) size, of the SMALL (670 × 377) image, from the question, where we set the quality to 40:
```
imagejpeg( $resource, $image, 40 );
```
[](https://i.stack.imgur.com/NLSvs.jpg)
Here's the same but with the quality set to 0:
```
imagejpeg( $resource, $image, 0 );
```
[](https://i.stack.imgur.com/cCVOu.jpg)
So it looks like we **don't** get the same behavior as described in the question, that when the quality is set to 40, it becomes 0, for the `hello-image` size of the 670x377 original image. |
271,226 | <p>I am currently trying my hand at creating a WP theme using angular JS.
I am trying to work through this tutorial: <a href="https://1fix.io/blog/2014/11/05/angularjs-json-api-wp-theme/" rel="nofollow noreferrer">https://1fix.io/blog/2014/11/05/angularjs-json-api-wp-theme/</a></p>
<p>However, I am near the end of this, and my ng-repeat is not returning a list of my posts.</p>
<p>This is my scripts.js: </p>
<pre><code>angular.module('app', ['ngRoute'])
.config(function($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider
.when('/', {
templateUrl: myLocalized.partials + 'main.html',
controller: 'Main'
})
.when('/:ID', {
templateUrl: myLocalized.partials + 'content.html',
controller: 'Content'

})
.controller('Main', function($scope, $http, $routeParams) {
$http.get('wp-json/wp/v2/posts/').then(function(res){
$scope.posts = res;
});
})
.controller('Content', function($scope, $http, $routeParams) {
$http.get('wp-json/wp/v2/posts' + $routeParams.id).then(function(res){
$scope.post = res;
});
});
</code></pre>
<p>And this is the code from my main.html:</p>
<pre><code><div ng-controller="Main">
<strong>This is the main page</strong>
<ul>
<li ng-repeat="post in posts">
<a href="{{ post.id }}">{{ post.title }}</a>
</li>
</ul>
</div>

<p>However, when I navigate to my page I only see:</p>
<p><a href="https://i.stack.imgur.com/smkkk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/smkkk.png" alt="enter image description here"></a></p>
<p>All the scripts seem to be enqueued correctly, and index.php is pulling main.html through, it just doesn't work.</p>
<p>I know it'll be something obvious, but my google foo has let me down </p>

| I am currently trying my hand at creating a WP theme using angular JS.
I am trying to work through this tutorial: <https://1fix.io/blog/2014/11/05/angularjs-json-api-wp-theme/>
However, I am near the end of this, and my ng-repeat is not returning a list of my posts.
This is my scripts.js:
```
angular.module('app', ['ngRoute'])
.config(function($routeProvider, $locationProvider) {
$locationProvider.html5Mode(true);
$routeProvider
.when('/', {
templateUrl: myLocalized.partials + 'main.html',
controller: 'Main'
})
.when('/:ID', {
templateUrl: myLocalized.partials + 'content.html',
controller: 'Content'
});
})
.controller('Main', function($scope, $http, $routeParams) {
$http.get('wp-json/wp/v2/posts/').then(function(res){
$scope.posts = res;
});
})
.controller('Content', function($scope, $http, $routeParams) {
$http.get('wp-json/wp/v2/posts' + $routeParams.id).then(function(res){
$scope.post = res;
});
});
```
And this is the code from my main.html:
```
<div ng-controller="Main">
<strong>This is the main page</strong>
<ul>
<li ng-repeat="post in posts">
<a href="{{ post.id }}">{{ post.title }}</a>
</li>
</ul>
</div>
```
However, when I navigate to my page I only see:
[](https://i.stack.imgur.com/smkkk.png)
All the scripts seem to be enqueued correctly, and index.php is pulling main.html through, it just doesn't work.
I know it'll be something obvious, but my google foo has let me down | It looks like the tutorial you linked is using `success`, and you've changed it to `then`.
The `success` method has been [deprecated](https://code.angularjs.org/1.5.10/docs/api/ng/service/$http#deprecation-notice), so you were correct to do that. However, because `then` returns data a little differently from `success`, you'll need to update your `$scope.post` variable accordingly:
`$scope.post = res.data;`
You can find a great explanation for the change in [this answer](https://stackoverflow.com/a/35331339/3194942). |

| My wp-config.php already has
```
define('ALLOW_UNFILTERED_UPLOADS', true);
```
But when I upload a .nb file, it shows "This file type is not allowed. Please try another"
How do I allow to upload any type of files? My WP version is 4.7.3. | ### Original Answer
Add the code below to your current theme's `functions.php`:
```
function wpse_add_nb_mime_type( $allowed_mimes ) {
$allowed_mimes['nb'] = 'application/mathematica';
return $allowed_mimes;
}
add_filter( 'mime_types', 'wpse_add_nb_mime_type', 10, 1 );
```
Remove `define`, mentioned in your question, from `wp-config.php`. Now you should be able to upload `.nb` files.
**Plugin alternative**: to make the code above, immune to theme changes, it's better to put it into a plugin. Create new file `wpse-addnbmimetype.php`, with this content:
```
<?php
/*
Plugin Name: WPSE Add NB Mime Type
Description: Adds 'nb' => 'application/mathematica' to allowable mime types
*/
function wpse_add_nb_mime_type( $allowed_mimes ) {
$allowed_mimes['nb'] = 'application/mathematica';
return $allowed_mimes;
}
function wpse_prepare_add_nb_mime_type() {
// this filter can be added as early as in init action
add_filter( 'mime_types', 'wpse_add_nb_mime_type', 10, 1 );
}
add_action( 'init', 'wpse_prepare_add_nb_mime_type' );
```
Put this file into '/wp-content/mu-plugins/' folder. Now you can switch themes, without losing ability to upload .nb files.
### Analysis
Read comments to @majick's answer, first. After all corrections, his filter will look like this:
```
add_filter('upload_mimes', 'modify_upload_mimes', 10, 2);
function modify_upload_mimes($t, $user) {
if ($user == null) {$user = wp_get_current_user();}
if (in_array('administrator', $user->roles)) {
$t['nb'] = 'application/mathematica';
}
return $t;
}
```
Does it work? Yes, but it does restrict uploads of files with .nb extensions to 'administrator' role only. Authors and editors will not be able to upload such files. Let's change it, by replacing line:
```
if (in_array('administrator', $user->roles)) {
```
with:
```
if ( $user->has_cap( 'upload_files' ) ) {
```
Now, authors, editors, and administrators can upload .nb files.
Checks against user's role should be discouraged, and should be made against user's capabilities, instead. If one day, we decide to add 'upload\_files' capability to contributor's role ( all contributors ), or to the individual user, our filter will work, without changes.
Why do we have two hooks, 'mime\_types' and 'upload\_mimes', to choose from? It is recommended, to use 'mime\_types' for adding mime types, and 'upload\_mimes' for removing ( to unset ) them.
There are two functions in '/wp-includes/functions.php': first -
`get_allowed_mime_types( $user = null )`, introducing 'upload\_mimes' filter hook, which was intended for arbitrary removal of 'swf', 'exe', and conditional removal of 'htm|html', mime types, and second - `wp_get_mime_types()`, introducing 'mime\_types' filter hook, intended for adding mime types.
### Conclusion
Technically, we could use either hook for our solution, but according to recommendations, 'mime\_types' should be used. No checks for user's capabilities are necessary, as both hooks will be triggered for users with 'upload\_files' capability, only. |

I don't want to touch my code since I'm new to WordPress. I want to do this only by WordPress itself. | I assume you are trying to add metadata to the header, such as Open Graph. To do so, you can hook into `wp_head` and output your content there directly. Add this piece of code to your theme's (or your child theme's) `functions.php` file:
```
//Hook to wp_head
add_action('wp_head','add_my_metadata');
function add_my_metadata(){
// Echo any content your wish here. Replace this with what you want.
echo '<meta name="keywords" content="Keyword1, Keyword2"/>';
}
```
Notice, that your theme must have `<?php wp_head(); ?>` in its `header.php` file in order for you to be able to output any content there.
UPDATE
------
If you are new to WordPress, you can install a plugin. There are plenty of known plugins that can do this for you, the most distinguished one is [Yoast SEO](https://wordpress.org/plugins/wordpress-seo/) which automatically does this for you. |
271,293 | <p>The theme I'm using makes extensive use of internal stylesheets to style various types of pages and their elements. For example, through their plugin UI, I can configure a specific page's hero layout and content... including font, size and color for various text elements. After configuring the hero and publishing the page, an internal stylesheet is added to the page's <code><head></code> tag:</p>
<pre><code><style id="ut-hero-custom-css" type="text/css">
#ut-hero .hero-inner {
text-align: right
}
.hero-description {
color: #000000;
}
.hero-description {
background: #FCB54B;
padding-bottom: 0;
margin-bottom: 5px;
}
#ut-hero .hero-title {
color: #1777FF;
}
</style>
</code></pre>
<p>Unfortunately, the plugin is limited in what it allows me to customize so I need to add some of my own CSS to fine tune things. Let's say I want to display a border around the block of text with <code>class="hero-description"</code>. I'd need to add </p>
<pre><code>.hero-description {
border: 1px solid #c00;
}
</code></pre>
<p>and have it be applied to the page AFTER the initial declaration above. Adding it my child-theme's style.css file or any other CSS file I register and enqueue adds it BEFORE. I was hoping that I could specify the inline stylesheet embedded by the plugin as a dependency for my new CSS file when enqueueing it, but I don't see any handle or reference to it in $wp_styles so I couldn't do that. Can you even register an internal stylesheet? </p>
<p>Anyway, this can be broken down to a very general problem. I want to have the "last word" on the page's CSS (excluding inline styles and scoped elements). Is there not a direct way to specify that a line of code such as:</p>
<pre><code><link rel="stylesheet" src="mycss.css">
</code></pre>
<p>always be included right before the closing <code></head></code> tag? </p>

| The theme I'm using makes extensive use of internal stylesheets to style various types of pages and their elements. For example, through their plugin UI, I can configure a specific page's hero layout and content... including font, size and color for various text elements. After configuring the hero and publishing the page, an internal stylesheet is added to the page's `<head>` tag:
```
<style id="ut-hero-custom-css" type="text/css">
#ut-hero .hero-inner {
text-align: right
}
.hero-description {
color: #000000;
}
.hero-description {
background: #FCB54B;
padding-bottom: 0;
margin-bottom: 5px;
}
#ut-hero .hero-title {
color: #1777FF;
}
</style>
```
Unfortunately, the plugin is limited in what it allows me to customize so I need to add some of my own CSS to fine tune things. Let's say I want to display a border around the block of text with `class="hero-description"`. I'd need to add
```
.hero-description {
border: 1px solid #c00;
}
```
and have it be applied to the page AFTER the initial declaration above. Adding it my child-theme's style.css file or any other CSS file I register and enqueue adds it BEFORE. I was hoping that I could specify the inline stylesheet embedded by the plugin as a dependency for my new CSS file when enqueueing it, but I don't see any handle or reference to it in $wp\_styles so I couldn't do that. Can you even register an internal stylesheet?
Anyway, this can be broken down to a very general problem. I want to have the "last word" on the page's CSS (excluding inline styles and scoped elements). Is there not a direct way to specify that a line of code such as:
```
<link rel="stylesheet" src="mycss.css">
```
always be included right before the closing `</head>` tag? | It's not elegant but it works.
Add these lines to functions.php:
```
ob_start();
add_action('shutdown', function() {
$final = '';
$levels = ob_get_level();
for ($i = 0; $i < $levels; $i++) {
$final .= ob_get_clean();
}
// append styles just before </head>
$final = str_replace( "</head>", '<link rel="stylesheet" src="mycss.css"></head>', $final );
echo $final;
}, 0);
```
Alternatively you can move all the inline styles at the beginning of the head, better if just after the title tag:
```
ob_start();
add_action('shutdown', function() {
$final = '';
$levels = ob_get_level();
for ($i = 0; $i < $levels; $i++) {
$final .= ob_get_clean();
}
/* Adjust the final output */
// load HTML DOM
$dom= new DOMDocument();
$dom->preserveWhiteSpace = false;
$dom->formatOutput = true;
$dom->loadHTML( '<?xml encoding="utf-8" ?>' . $final );
// collect styles and remove them from DOM
$inline_styles = "";
$styles = $dom->getElementsByTagName("style");
foreach( $styles as $style )
{
$inline_styles .= $dom->saveHTML( $style );
$style->parentNode->removeChild( $style );
}
$final = $dom->saveHTML();
// strip utf-8 workaround
$final = str_replace( '<?xml encoding="utf-8" ?>', "", $final );
// append styles after <title>
$final = str_replace( "</title>", "</title>\n" . $inline_styles, $final );
echo $final;
}, 0);

| I'm trying to format a number in a table cell with comma separators between thousands. The number is coming from a custom field generated in Advanced Custom Fields plugin, where it is required to be a number.
(But I've also tried just entering the number directly in the below examples.)
I'm getting the correct number value, but the formatting isn't working. Plus, I get different results from number\_format inside a table cell and outside one.
My number is 429000, retrieved by the\_field('price').
Here's what I've tried inside the cell:
```
<td class="pl-property-price"><?php number_format( the_field('price')); ?> </td>
<td class="pl-property-price"><?php number_format((int) the_field('price')); ?> </td>

<td class="pl-property-price"><?php number_format( the_field('price'), 0, ".", ","); ?> </td>
```
and some other variations.
No matter what I do, it outputs 429000 without the comma separator.
Now, if I try to echo the value outside the table, using code like this and all the similar variations to the above using
```
<?php echo number_format(the_field('price')); ?>
```
I get 4290000 which adds an extra zero.
I'm puzzled. | Seems like the function you using is the [the\_field](https://www.advancedcustomfields.com/resources/the_field/) function from of [ACF](https://www.advancedcustomfields.com) which is a function that outputs a string so the formatting number\_formatt dosent effect the output.
This code:
```
<?php echo number_format(the_field('price')); ?>
```
The echo does not really print anything, the function the\_fields prints the output, that's the reason the number\_format function doesn't have any effect on the output.
Try getting the field via different function [get\_field](https://www.advancedcustomfields.com/resources/get_field/) for example, or you could add the the function the\_fields a $format\_value argument like you could see in the [docs](https://www.advancedcustomfields.com/resources/the_field/) .
This should work:
```
<?php echo number_format( get_field( 'price' ) ); ?>

<p><a href="https://i.stack.imgur.com/ZSlEo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ZSlEo.png" alt="enter image description here"></a></p>
<p>I'm wondering if I've gone about this the wrong way. If I create the new pages in WordPress instead of manually via FTP, will this allow me to change the permalink structure so that I can have <code>new.gatewaywebdesign.com/contact.php</code> instead of <code>new.gatewaywebdesign.com/wp-content/themes/gatewaywebdesign/contact.php</code>? </p>
<p>I went ahead and tried to create a <code>contact</code> page in the WordPress dashboard but it won't let me get rid of <code>index.php</code> after the site name:</p>
<p><a href="https://i.stack.imgur.com/EKsEZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/EKsEZ.png" alt="enter image description here"></a></p>
<p>Any other suggestions for editing / trimming link structure? Thanks</p>

| I'm trying to create a custom WordPress theme from scratch. As you can see, my file structure looks like this - footer.php, header.php, index.php, about.php, and contact.php within my theme folder:
[](https://i.stack.imgur.com/zLjPX.png)
I've completed the home page (index.php) and now I'm trying to create these other pages and link to them. But when I go to these pages from the [home page](http://new.gatewaywebdesign.com/), the only way that I could get them to link was through this long, ugly link structure:

Any other suggestions for editing / trimming link structure? Thanks | The answer to this question is yes, creating the pages in WordPress does allow you to change the link structure. What I needed to do was rework `index.php` so that it used the [WordPress Loop](https://codex.wordpress.org/The_Loop), and then displayed the front page as whatever the front page was set to in the WordPress dashboard. So my `index.php` ended up looking like this:
```
<?php get_header();?>
<?php if ( have_posts() ) : ?>
// Set front page
<?php if ( is_home() && ! is_front_page() ) : ?>
// Display page title
<header>
<h1 class="page-title screen-reader-text"><?php single_post_title(); ?></h1>
</header>
<?php endif; ?>
<?php
// Start the loop.
while ( have_posts() ) : the_post();
/*
* Include the Post-Format-specific template for the content.
* If you want to override this in a child theme, then include a file
* called content-___.php (where ___ is the Post Format name) and that will be used instead.
*/
get_template_part( 'content', get_post_format() );
// End the loop.
endwhile;
// Previous/next page navigation.
/* the_posts_pagination( array(
'prev_text' => __( 'Previous page', 'twentyfifteen' ),
'next_text' => __( 'Next page', 'twentyfifteen' ),
'before_page_number' => '<span class="meta-nav screen-reader-text">' . __( 'Page', 'twentyfifteen' ) . ' </span>',
) );*/
// If no content, include the "No posts found" template.
else :
get_template_part( 'content', 'none' );
endif;
?>
<?php get_footer();?>
```
Make sure that your theme has all the necessary core files - `single.php`, `content-link.php`, `content-none.php`, `content-page.php`, `content-search.php`, `content.php`, and `page.php`.
Then in WordPress, create a menu and set the pages that you've created in WordPress to be in that menu.
In `header.php`, set the links to the different pages in your nav menu like this:
```
<div class="menu-container"><!--menu items-->
<?php $main_menu = inits_get_main_menu();
foreach ($main_menu as $menu) { //var_dump( $menu); exit; ?>
<div class="menu-item contact">
<a class="menu-link" href="<?php echo $menu->url; ?>">
<?php echo $menu->title; ?>
</a>
</div>
<?php } ?>
</div>
```
Now your menu has been set in the header, and when you click on one of the links to your other pages, the link structure will look the way that you want it to. |

Ask your host. This is definitely not WordPress native behaviour.

function prepend_default_rewrite_rules( $rules ) {
// Prepare for new rules
$new_rules = [];
// Set up languages, except default one
$language_slugs = ['ar', 'ku'];
// Generate language slug regex
$languages_slug = '(?:' . implode( '/|', $language_slugs ) . '/)?';
// Set up the list of rules that don't need to be prefixed
$whitelist = [
'^wp-json/?$',
'^wp-json/(.*)?',
'^index.php/wp-json/?$',
'^index.php/wp-json/(.*)?'
];
// Set up the new rule for home page
$new_rules['(?:' . implode( '/|', $language_slugs ) . ')/?$'] = 'index.php';
// Loop through old rules and modify them
foreach ( $rules as $key => $rule ) {
// Re-add those whitelisted rules without modification
if ( in_array( $key, $whitelist ) ) {
$new_rules[ $key ] = $rule;
// Update rules starting with ^ symbol
} elseif ( substr( $key, 0, 1 ) === '^' ) {
$new_rules[ $languages_slug . substr( $key, 1 ) ] = $rule;
// Update other rules
} else {
$new_rules[ $languages_slug . $key ] = $rule;
}
}
// Return out new rules
return $new_rules;
}
add_filter( 'rewrite_rules_array', 'prepend_default_rewrite_rules' );
```
Haven't tested it to full extent - just came up with the solution after studying the WP\_Rewrite class. So it's a work in progress. Hope it helps though.
P.S.: Also, I would be happy to see your solution for "I retrieve the value from the URL to determine the language/country = complete" - that's what I'm currently working on :) |

More about the [wp\_trash\_post()](https://codex.wordpress.org/Function_Reference/wp_trash_post) function.
The opposite is:
```
wp_untrash_post( $post_id );
```
`wp_untrash_post()` also untrashes trashed comments.
In WP there are functions for many things - for instance you can trash/untrash only comments, leaving the post alone - in that case use: `wp_untrash_post_comments()` and `wp_trash_post_comments()`. |

271,425 | <p>I am experimenting creating a WordPress plugin using create-react-app. To make things simple, I am trying to develop a click-to-tweet plugin.</p>
<p>The shortcode part (in PHP ) looks like:</p>
<pre><code>// Shortcode to output needed markup
add_shortcode( 'react_click_to_tweet', 'react_click_to_tweet_test' );
function react_click_to_tweet_test($atts = [], $content = null, $tag = '') {
return '<div id="root" data=' . $content . '></div>';
}
function include_react_files() {
wp_enqueue_style( 'prefix-style', plugins_url('css/main.ae114d0c.css', __FILE__) );
// add the JS file to the footer - true as the last parameter
wp_enqueue_script( 'plugin-scripts', plugins_url('js/main.d8745ba2.js', __FILE__),array(), '0.0.1', true );
}
add_action( 'wp_enqueue_scripts', 'include_react_files' );
</code></pre>
<p>$content should be the text to tweet that I want to pass with the shortcode as:</p>
<pre><code>[react_click_to_tweet]TEXT TO TWEET[/react_click_to_tweet]
</code></pre>
<p>The index.js has:</p>
<pre><code>ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();
</code></pre>
<p>But this isn't working.
Any suggestions?</p>
<p>Furthermore, how aI can pass $atts to pass for example attributes to modify the CSS at runtime?</p>
<p>[edit] Based on the suggestions @Paul Burilichev and @belinus I have done the following changes:</p>
<p>I tried what they have about <a href="https://developer.wordpress.org/plugins/javascript/" rel="nofollow noreferrer">WP AJAX</a> for shortcodes with parameters. I tried: </p>
<pre><code>add_shortcode( 'react_click_to_tweet', 'react_click_to_tweet_test' );
function react_click_to_tweet_test($atts = [], $content = null, $tag = '') {
$o = '';
$o .= '<div id="tweet" >';
if (!is_null($content)) {
$o .= apply_filters('content', $content);
// run shortcode parser recursively
$o .= do_shortcode($content);
}
// end box
$o .= '</div>';
return $o; //'<div id="root" ></div>';
}
</code></pre>
<p>but, it doesn't work. What am I missing?</p>
<p>Then, I tried:</p>
<pre><code>function include_react_files() {
wp_enqueue_style( 'prefix-style', plugins_url('css/main.ae114d0c.css', __FILE__) );
// add the JS file to the footer - true as the last parameter
wp_register_script( 'plugin-scripts', plugins_url('js/main.d8745ba2.js', __FILE__),array(), '0.0.1', true );
$data = array(
'text' => $content, // I also tried passing a string 'some content goes here'
'key2' =? 'value2',
);
wp_localize_script( 'plugin-scripts', 'wp_object', $data );
wp_enqueue_script( 'plugin-scripts' );
}
add_action( 'wp_enqueue_scripts', 'include_react_files' );
</code></pre>
<p>but object is not recognized on my App component. I guess I am still missing something here. my index.js looks like: </p>
<pre><code>import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import './index.css';
//const data = "This is some cool stuff";
ReactDOM.render(
<App />, document.getElementById('root'));
registerServiceWorker();
</code></pre>
<p>And this is my App.js:</p>
<pre><code>import React, { Component } from 'react';
import './App.css';

| I am experimenting creating a WordPress plugin using create-react-app. To make things simple, I am trying to develop a click-to-tweet plugin.
The shortcode part (in PHP ) looks like:
```
// Shortcode to output needed markup
add_shortcode( 'react_click_to_tweet', 'react_click_to_tweet_test' );
function react_click_to_tweet_test($atts = [], $content = null, $tag = '') {
return '<div id="root" data=' . $content . '></div>';
}
function include_react_files() {
wp_enqueue_style( 'prefix-style', plugins_url('css/main.ae114d0c.css', __FILE__) );
// add the JS file to the footer - true as the last parameter
wp_enqueue_script( 'plugin-scripts', plugins_url('js/main.d8745ba2.js', __FILE__),array(), '0.0.1', true );
}
add_action( 'wp_enqueue_scripts', 'include_react_files' );
```
$content should be the text to tweet that I want to pass with the shortcode as:
```
[react_click_to_tweet]TEXT TO TWEET[/react_click_to_tweet]
```
The index.js has:
```
ReactDOM.render(<App />, document.getElementById('root'));
registerServiceWorker();
```
But this isn't working.
Any suggestions?
Furthermore, how aI can pass $atts to pass for example attributes to modify the CSS at runtime?
[edit] Based on the suggestions @Paul Burilichev and @belinus I have done the following changes:
I tried what they have about [WP AJAX](https://developer.wordpress.org/plugins/javascript/) for shortcodes with parameters. I tried:
```
add_shortcode( 'react_click_to_tweet', 'react_click_to_tweet_test' );
function react_click_to_tweet_test($atts = [], $content = null, $tag = '') {
$o = '';
$o .= '<div id="tweet" >';
if (!is_null($content)) {
$o .= apply_filters('content', $content);
// run shortcode parser recursively
$o .= do_shortcode($content);
}
// end box
$o .= '</div>';
return $o; //'<div id="root" ></div>';
}
```
but, it doesn't work. What am I missing?
Then, I tried:
```
function include_react_files() {
wp_enqueue_style( 'prefix-style', plugins_url('css/main.ae114d0c.css', __FILE__) );
// add the JS file to the footer - true as the last parameter
wp_register_script( 'plugin-scripts', plugins_url('js/main.d8745ba2.js', __FILE__),array(), '0.0.1', true );
$data = array(
'text' => $content, // I also tried passing a string 'some content goes here'
'key2' =? 'value2',
);
wp_localize_script( 'plugin-scripts', 'wp_object', $data );
wp_enqueue_script( 'plugin-scripts' );
}
add_action( 'wp_enqueue_scripts', 'include_react_files' );
```
but object is not recognized on my App component. I guess I am still missing something here. my index.js looks like:
```
import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import './index.css';
//const data = "This is some cool stuff";
ReactDOM.render(
<App />, document.getElementById('root'));
registerServiceWorker();
```
And this is my App.js:
```
import React, { Component } from 'react';
import './App.css';
class App extends Component {
render() {
const page = window.location.href;
let data = page+'&text='+ wp_object.text;
let twiiterUrl = "https://"+"twitter.com/intent/tweet?url=";
let URL = twiiterUrl+data;
//console.log(wp_object.text);
return (
<div className="App">
<div className="tm-click-to-tweet">
<div className="tm-ctt-text">
<a href={URL} target="_blank">{wp_object.text} </a>
</div>
<a href={URL} className="tm-ctt-btn" target="_blank">Click To Tweet</a>
<div className="tm-ctt-tip"></div>
<div className="clear"></div>
</div>
</div>
);
}
}
export default App;
```

| How can I set the default subtitle in wordpress videos?
Here is the shortcode that wp created after adding a video with a subtitle from media:
```
[video
width="960"
height="540"
mp4="example.com/wp-content/uploads/test.mp4"
]<track
srclang="En"
label="English"
kind="subtitles"
src="example.com/wp-content/uploads/test.vtt"
/>[/video]
```
Now when I see the post in FO, I have to click on "cc" in video control bar and choose "English". The default is "None".
Now how can I change this default to English so that the user doesn't have to choose subtitle? | Please have look on the below code block-
```
$args = array(
"hide_empty" => 0,
"type" => "post",
"orderby" => "name",
"order" => "ASC"
);
$types = get_categories($args);
foreach ( $types as $type) {
wp_delete_category( $type->ID );
}
```
The function [`wp_delete_category`](https://codex.wordpress.org/Function_Reference/wp_delete_category) will delete a single category. So we need to run a loop through `$types` to delete each single category.
Hope that helps. |

What I am trying to do, is to set it so that when the homepage is shared, a specific, default image will be displayed. However, the image must only be displayed when the homepage is shared, and should not otherwise appear on the site. What would be the best way to do this? | Several options:
**Out-of-the-box plugin**
If you're using Yoast WordPress SEO, you have a built-in setting for Facebook images. Under your SEO > Social menu, go to the Facebook tab and select an image under "Frontpage settings." You can also set an image as a fallback, for posts that have no featured image, under "Default settings."
Other SEO plugins may have similar capabilities.
**Child theme**
You can create a child theme or modify a custom theme. First, make sure the theme supports a site logo. If not, [add custom logo support](https://codex.wordpress.org/Theme_Logo).
Next, edit or copy `header.php` into your new child theme. Inside the `<head></head>` tags, include a check for `if(is_front_page())` or `if(is_home())` depending on your needs. Sounds like either would work in your case.
If the condition is met, grab the custom logo URL
```
$image = wp_get_attachment_image_url(get_theme_mod('custom_logo'), 'large');
```
and output it within Open Graph tags:
```
<meta property="og:image" content="<?php echo $image; ?>" />
<meta name="twitter:image" content="<?php echo $image; ?>" />
```
**Custom plugin**
You could also create your own plugin, if you don't want to use Yoast WordPress SEO or fiddle with the theme. The risk is that an existing theme or plugin may already output a featured image, so you'd want to check your page source and make sure nothing else is setting a featured image. I assume this is the case since your current theme and plugins are setting the most-recently-published post's image when you try to share it.
Basically, you would add an action for the `wp_head` hook. Your action would output the Open Graph and Twitter image data just like you would if you chose the first option, working with the theme.
You'd have to decide whether to hard-code the image into your plugin, or whether you would create an options page somewhere in wp-admin where you could change the image whenever you wanted. |

I understand that there is a [similar question](https://wordpress.stackexchange.com/questions/41988/redeclare-change-slug-of-a-plugins-custom-post-type), but
1. it 5 years old and I hope there can be an easier way,
2. it doesn't cover the name part | WordPress provides the [`register_post_type_args` filter](https://developer.wordpress.org/reference/hooks/register_post_type_args/) to let users do this:
```
function wpd_modify_post_type( $args, $post_type ){
if( 'reviews' == $post_type ){
$args['labels']['name'] = 'New name';
$args['labels']['singular_name'] = 'New singular name';
$args['rewrite']['slug'] = 'new-slug';
}
return $args;
}
add_filter( 'register_post_type_args', 'wpd_modify_post_type', 10, 2 );

| I'm looking for widget or php query which I will be able to use as something like "on this day in history".
This query I want to show:
Posts published in the past on the same day and month, from whole years of publication.
Thank you in advance for help. | The problem is that you're trying to use `is_page()`, a conditional function intended only to run adjacent to the query, too early. Try running your code inside a callback that 1) only fires on the front-end, 2) fires after the page has partially loaded. For instance, `wp_head`.
```
function prefix_run_on_contact_us() {
if( is_page('contact-us')) {
echo "hello check";
//either in about us, or contact, or management page is in view
} else {
echo "Not working";
}
}
add_action( 'wp_head', 'prefix_run_on_contact_us' );

Thanks | You dont need to modify your template files for this, instead you can use the WooCommerce hook `woocommerce_after_add_to_cart_button`. This hook will add content after the "Add to cart" button.
If the customer clicks on this button, the product should get added to the cart, and the customer should be send to the checkout page, right?!
Basically you can add products to the cart with a link like this:
```
http://example.com/cart/?add-to-cart=<product ID>
```
So, using the hook mentioned above, and keeping this URL in mind, we can add a second button with this snippet:
```
function add_content_after_addtocart() {
// get the current post/product ID
$current_product_id = get_the_ID();
// get the product based on the ID
$product = wc_get_product( $current_product_id );
// get the "Checkout Page" URL
$checkout_url = WC()->cart->get_checkout_url();
// run only on simple products
if( $product->is_type( 'simple' ) ){
echo '<a href="'.$checkout_url.'?add-to-cart='.$current_product_id.'" class="single_add_to_cart_button button alt">Checkout</a>';
}
}
add_action( 'woocommerce_after_add_to_cart_button', 'add_content_after_addtocart' );
```
This will add a button after the normal Add to cart button on single product pages.
As you can see I also added a check to see if the current product is a simple product or not. If you want to use this with variation, it is more difficult.
With these products you need to generate an URL like:
```
http://example.com/cart/?add-to-cart=123&variation_id=456&attribute_pa_colour=black
```
---
Maybe you also need to check the default WooCommerce option `Enable AJAX Add to cart` (WooCommerce > Products > Display). I have not tested it with this setting.
---
**Update** to include the quantity
If you want to add a quantity you can also append a parameter to our button URL, like so:
```
http://example.com/cart/?add-to-cart=<product ID>&quantity=<number of quantity>
```
However, since a customer can change the quantity with the WooCommerce input-field, we need a way to get the current value of this field.
So we have multiple options here,
* listen to an on-change event on the quantity field to update our URL,
* or append the current value of the quantity field to the URL, only
if our custom button is clicked.
The following code uses the second approach, only when the button is clicked the parameter gets added.
Inside the `if( $product->is_type( 'simple' ) )` function, before the echo, enter this script:
```
<script>
jQuery(function($) {
<?php /* if our custom button is clicked, append the string "&quantity=", and also the quantitiy number to the URL */ ?>
// if our custom button is clicked
$(".custom-checkout-btn").on("click", function() {
// get the value of the "href" attribute
$(this).attr("href", function() {
// return the "href" value + the string "&quantity=" + the current selected quantity number
return this.href + '&quantity=' + $('input.qty').val();
});
});
});
</script>
```
I did not included stop and start PHP tags in the code above! So you need to end PHP before the (?>) and start it again after the script ( |

Would I have to add a new .js file to the child theme, or could the script go into functions.php? Or, even better, could it be added with a plugin? | You can do different things:
1. **Enqueue** the new JS file via `plugin`
2. **Enqueue** the new JS file via `functions.php`
3. Add your JS code into `functions.php` through `wp_header` or `wp_footer`
For adding new JS files to a wordpress site you should **enqueue** these files with `wp_enqueue_style()` and/or `wp_enqueue_script()`.
This is the proper and safest way.
I would go the route and create a simple, small plugin for that, because this is theme independent.
You *could* also use an hook to `wp_header` or `wp_footer`. Inside this hook you can write your JS code.
But the proper way is enqueueing these files which will work something like this:
```
function prfx_frontend_enqueue() {
wp_enqueue_style( 'my-plugin-css', plugins_url('/assets/css/plugin.css', __FILE__) );
wp_enqueue_script( 'my-plugin-js', plugins_url('/assets/js/jquery.my-script-min.js', __FILE__), array('jquery'));

| I am trying to customize the search results for a generic search, but **only** if it's using the `search.php` template. I have other searches on my site, and I don't want this filter interfering with them. Everything works on the following code, except for `is_page_template('search.php')`.
Once I enter that line of code as a condition, it just reverts to the normal search filtering, because my IF condition is failing. How do I only run my code if we're on the `search.php` page?

}
add_filter('pre_get_posts', 'SearchFilter');
``` | Lets break it down step by step:
`if ($query->is_search && is_page_template('search')) {`
There are 3 problems here
`is_page_template`
------------------
`search.php` isn't a page template, that's not how the search template is loaded. So this won't work.
But if it did work, there's a new problem. Functions such as `is_page_template` etc rely on the main query, but we're in a `pre_get_posts` filter, you don't know if that query has been set yet, or if you're filtering that query or another.
So we need to:
* remove the `is_page_template` check, it doesn't do what you think it does
* Add an `$query->is_main_query()` check so the filter doesn't interfere with widgets and other queries
Methods vs member variables
---------------------------
`if ($query->is_search`
This doesn't work, and should be generating PHP warnings for you. The problem is that `is_search` is a function/method not a variable, it should be:
`if ( $query->is_search() && $query->is_main_query() ) {`
But `search.php`?
-----------------
WordPress decides which template is loaded based on the main query. If it's the main query, and `is_search` is true, then `search.php` will be loaded.
Because of this, WordPress hasn't decided which template to use when your filter happens. In fact, you can make WordPress change which template it loads by modifying the query variables. For example, if you unset all the variables, and tell it to load a single post, you won't get `search.php`, or an archive at all, you're likely to get `single.php` instead
What About Search Queries in Page Templates?
--------------------------------------------
`is_main_query` will be false, so not an issue |

271,662 | <p>I have a subdomain multisite network. I have implemented a system in order to create new subdomains programmatically, just filling a form.</p>
<p>Now I have a need: when a new blog is created, I'd like to set its permalink structure to /postname/.</p>
<p>I've tried these solutions:</p>
<p><strong><a href="https://wordpress.stackexchange.com/questions/31207/how-to-set-permalink-structure-via-functions-php">How to set permalink structure via functions.php</a></strong></p>

}
add_action('wpmu_activate_blog', 'set_default_permalink_for_new_blogs');
</code></pre>
<p>I've added this snippet in the functions.php of the theme used for the main site, where the system above mentioned is. It simply doesn't work.</p>
<p><strong><a href="https://wordpress.stackexchange.com/questions/36306/how-do-i-programmatically-force-custom-permalinks-with-my-theme">How Do I Programmatically Force Custom Permalinks with My Theme?</a></strong></p>

</code></pre>
<p>I have some concerns with this snippet: I don't think it could be a good idea to fire the rewrite on every "init" (also someone else expressed doubt about this in comments); in second place, this snippet has to be placed on the default theme of new blogs - but what if I want to change the default theme in future?</p>

| I have a subdomain multisite network. I have implemented a system in order to create new subdomains programmatically, just filling a form.
Now I have a need: when a new blog is created, I'd like to set its permalink structure to /postname/.
I've tried these solutions:
**[How to set permalink structure via functions.php](https://wordpress.stackexchange.com/questions/31207/how-to-set-permalink-structure-via-functions-php)**
```
function set_default_permalink_for_new_blogs($blog_id)
{
global $wp_rewrite;
$wp_rewrite->set_permalink_structure( '/%year%/%monthnum%/%postname%/' );
}
add_action('wpmu_activate_blog', 'set_default_permalink_for_new_blogs');
```
I've added this snippet in the functions.php of the theme used for the main site, where the system above mentioned is. It simply doesn't work.
**[How Do I Programmatically Force Custom Permalinks with My Theme?](https://wordpress.stackexchange.com/questions/36306/how-do-i-programmatically-force-custom-permalinks-with-my-theme)**
```
function change_permalinks() {
global $wp_rewrite;
$wp_rewrite->set_permalink_structure('/%postname%/');
$wp_rewrite->flush_rules();
}
add_action('init', 'change_permalinks');
```
I have some concerns with this snippet: I don't think it could be a good idea to fire the rewrite on every "init" (also someone else expressed doubt about this in comments); in second place, this snippet has to be placed on the default theme of new blogs - but what if I want to change the default theme in future?
Thank you very much for every suggestions,
Marco | With a "mu-plugins", the solution is...
```
add_action( 'wpmu_new_blog', function( $blog_id ){
switch_to_blog( $blog_id );
global $wp_rewrite;
$wp_rewrite->set_permalink_structure('/%postname%/');
$wp_rewrite->flush_rules();
restore_current_blog();
}, 10 );

271,677 | <p><strong>Short description:</strong> I've created a bunch of terms and attached them to an existing taxonomy for a certain custom-post that already exist using the SQL code below. After doing this I'd like to update wp_term_taxonomy.count . I set it to 0 (dumb?) so the new terms are not appearing in search forms (they do appear on the individual custom post though). Setting count to 1 fixes this but still 'wrong' and I'm worried this could cause issues down the line.</p>
<p>Answers within SQL or Wordpress will work though my coding is just above n00b status. </p>
<p><strong>My solution:</strong> set wp_term_taxonomy.count to 1 for new terms so it'll appear across the site. I can use them in searches (important) but things like tag clouds are wrong/mis-sized (fine) and I'm worried I'll run into unknown issues.</p>
<p><strong>Details:</strong>
I am adding many terms to a taxonomy I have already created called 'csf_brand' for a custom post type called 'jeans'. Rather than editing each of several hundred custom posts already created I thought I'd batch them with SQL, using the 3 tables related to custom taxonomies. </p>
<p>First I create my new terms.</p>
<pre><code>INSERT INTO `wp_nhyb_terms` (`term_id`, `name`, `slug`, `term_group`) VALUES
(10, 'GAP', 'gap', 0); --there's a bunch more lines like this adding in new terms
</code></pre>
<p>Next, I attach my terms to the appropriate taxonomy. 0 is not the right count but calculating this is not something I'm interested in doing if I can avoid it. </p>
<pre><code>INSERT INTO `wp_nhyb_term_taxonomy` (`term_taxonomy_id`, `term_id`, `taxonomy`, `description`, `parent`, `count`) VALUES
(10, 10, 'csf_brand', '', 0, 0); --Here is where I could use 1 instead of 0
</code></pre>
<p>Finally, I attach the terms to my custom post types by the post ID (object_id)</p>
<pre><code>INSERT INTO `wp_nhyb_term_relationships` (`object_id`, `term_taxonomy_id`, `term_order`) VALUES
(125, 10, 0);
</code></pre>
<p>And that works. But wp_term_taxonomy.count is not 0 so they aren't appearing in my searches (e.g. I have a page that can search for brands via dropdown and they aren't an option). If I edit a custom post in my browser then save it recognizes the new term and corrects the count. But that's not a great process since I'll eventually miss something. </p>

271,682 | <h2><strong>The Problem</strong></h2>
<p>So I installed a plugin (iHomeFinder's Optima Express), and it works perfectly fine. The page it made is
<a href="http://conradbowenrealestate.com/homes-for-sale-search/" rel="nofollow noreferrer">conradbowenrealestate.com/homes-for-sale-search</a>. However, this page isn't made in WordPress, it doesn't even exist to it. I want to make it the homepage, but since WordPress doesn't recognize it as a WP page, I can't set it as the homepage. <strong>Note that when viewing the source code, the "page-id" is 0.</strong></p>
<h2><strong>What I've Tried</strong></h2>
<p>I've tried using this code in the functions.php file, but it doesn't enact any change on the website:</p>
<pre><code>$homepage = get_page('0');
if ( $homepage )
{
update_option( 'page_on_front', $homepage->ID );
update_option( 'show_on_front', 'page' );
}
</code></pre>
<p>It does work if I change the ID to one of the pages listed in my WP-Admin's "Pages" section. <code>get_page_by_title</code> doesn't work since again, that's for WP pages and this is invisible to WP.</p>
<p>I've also tried recreating the object on the plugin page by going to the source code and copy/pasting it to my homepage's code. While it does work and is functional, it is out of proportions (too much space between options).</p>
<h2><strong>My Question</strong></h2>
<p>How can I get this search plugin on my homepage? I want the above mentioned plugin page to be what shows when you go to <a href="http://conradbowenrealestate.com/" rel="nofollow noreferrer">conradbowenrealestate.com</a>.</p>
<h2><strong>Edit:</strong></h2>
<p>I failed to mention that within the plugin settings, I am limited to: <a href="http://conradbowenrealestate.com/" rel="nofollow noreferrer">http://conradbowenrealestate.com/</a> [insert text here] /. If I leave it blank, it won't save.</p>

| In my projects I have some components which I use in a lot of custom Plugins as well as in some custom coded Themes like e.g. admin image or video selectors.
Those I am holding in custom git repositories. However as those components are used in both - themes and plugins - I always have to manually change the URL getters after pulling from GIT. If the components exist multiple times its not a problem I have wrapped those with `function_exists`.
This is what I use in the Theme:
```
wp_enqueue_script(get_template_directory_uri().'/libs/my_lib/admin_image_upload', ...);
```
This is what I use in a Plugin:
```
wp_enqueue_script(plugins_url(__FILE__).'admin_image_upload.js', ...);
```
Is there a way to determine if my current PHP file is within the plugins' folder or within the themes' folder in order that I can let decide for the correct path automatically? | >

Broadly you always have path to current file (`__FILE__`) so you can always examine it for where you are and compare with context. This might be good enough in custom site, but likely too brittle for public code. There are plenty of edge cases with paths since they can be highly customized.
What you have is not just *asset* problem, but *dependency* problem — how do you reuse multiple components, in different ways, and without conflicts.

``` | Plugins typically insert their content via `the_content` filter. The filter runs when `the_content()` function is called, and passes the content through the filter before output.
Remember, with a filter, you need to append to the existing content, then `return` the results.
```
add_filter( 'the_content', 'wpd_content_filter', 10 );
function wpd_content_filter( $content ){
if ( is_single() && get_field( 'review_score' ) )
$content .= '<span class="review-the-score">' . get_field( 'review_score' ) . '</span>';
return $content;

How can I make sure the comment for a specific post type are separated from the general comments in the dashboard area? | All comments are just listed under **"Comments"** there is no attribute or parameter which creates a seperate **"Comments"** section/page for your custom post-type. Atleast not that I know of.
*However, you could add a filter to the comments list, to filter all comments based on post-types.*
It will be just like a category filter in the post list.
So you can create a `HTML select field`, which contains an `option for every custom post-type`. The `value` of each option needs to be the `slug of the post-type`. The `select` element needs `a name of "post_type"` to make the filtering work.
```
/**
* Create custom comments filter for post types
**/
function my_comments_filter() {
// we are only getting the none-default post types here (no post, no page, no attachment)
// you can also change this, just take a look at the get_post_types() function
$args = array(
'public' => true,
'_builtin' => false
);
$post_types = get_post_types( $args, 'objects' ); // we get the post types as objects
if ($post_types) { // only start if there are custom post types
// make sure the name of the select field is called "post_type"
echo '<select name="post_type" id="filter-by-post-type">';
// I also add an empty option to reset the filtering and show all comments of all post-types
echo '<option value="">'.__('All post types', 'my-textdomain').'</option>';
// for each post-type that is found, we will create a new <option>
foreach ($post_types as $post_type) {
$label = $post_type->label; // get the label of the post-type
$name = $post_type->name; // get the name(slug) of the post-type
// value of the optionsfield is the name(slug) of the post-type
echo '<option value="'.$name.'">'.$label.'</option>';
}
echo '</select>';
}
}
// we add our action to the 'restrict_manage_comments' hook so that our new select field get listet at the comments page
add_action( 'restrict_manage_comments', 'my_comments_filter' );
```
If you add this code to your `functions.php`, or better, `to a plugin`, you will see a new filter on the top of the comments backend. Here you can `select a custom post-type` and than click on `Filter`, to filter the comments. If you select "All post types" and click filter again, all comments should show. |

Any help or assistance would be awesome. I don't quite know where to start.
Paul. | This is because the `site_url` and `homeurl` of your original installation are set to HTTPS in the database, so you can't access your website on localhost unless you:
1. Change these values to non-ssl
2. Install a SSL certificate on localhost
I will only explain the first case since installing a certificate is out of this community's scope.
To do this, you have 2 options.
Directly edit the downloaded SQL file
-------------------------------------
Open the MySQL export that you just downloaded from your server. Search for `wp_options` and you will find a line in your database like this:
```
INSERT INTO `wp_options` (`option_id`, `option_name`, `option_value`, `autoload`) VALUES
```
The 2 lines below this one are `siteurl` and `homeurl`. Change both of their values to `http://localhost/`. Pay attention to quotes and commas! So, the 3 first line will look like this:
```
INSERT INTO `wp_options` (`option_id`, `option_name`, `option_value`, `autoload`) VALUES
(1, 'siteurl', 'http://localhost/', 'yes'),
(2, 'home', 'http://localhost', 'yes'),
```
Then upload your SQL file. That's it.
Update the values by PHPMyAdmin
-------------------------------
If you have PHPMyAdmin installed on your localhost, or you have enough knowledge to directly update the tables via command line, the proceed with this method.
Login to your database by PHPMyAdmin. From the left navigation menu, choose the proper database. Now, select the `wp_options` table from the right section.
Again, the two beginning values will be `siteurl` and `homeurl`, which you can simply update to `http://localhost/` without worrying about making a mistake by editing the original SQL file. |

| I want to create new post page after every 25 (li /li) tags. Is it possible? | This is because the `site_url` and `homeurl` of your original installation are set to HTTPS in the database, so you can't access your website on localhost unless you:
1. Change these values to non-ssl
2. Install a SSL certificate on localhost
I will only explain the first case since installing a certificate is out of this community's scope.
To do this, you have 2 options.
Directly edit the downloaded SQL file
-------------------------------------
Open the MySQL export that you just downloaded from your server. Search for `wp_options` and you will find a line in your database like this:
```
INSERT INTO `wp_options` (`option_id`, `option_name`, `option_value`, `autoload`) VALUES
```
The 2 lines below this one are `siteurl` and `homeurl`. Change both of their values to `http://localhost/`. Pay attention to quotes and commas! So, the 3 first line will look like this:
```
INSERT INTO `wp_options` (`option_id`, `option_name`, `option_value`, `autoload`) VALUES
(1, 'siteurl', 'http://localhost/', 'yes'),
(2, 'home', 'http://localhost', 'yes'),
```
Then upload your SQL file. That's it.
Update the values by PHPMyAdmin
-------------------------------
If you have PHPMyAdmin installed on your localhost, or you have enough knowledge to directly update the tables via command line, the proceed with this method.
Login to your database by PHPMyAdmin. From the left navigation menu, choose the proper database. Now, select the `wp_options` table from the right section.
Again, the two beginning values will be `siteurl` and `homeurl`, which you can simply update to `http://localhost/` without worrying about making a mistake by editing the original SQL file. |

| I am trying to filter by a meta query but no matter what I try I can not make it work.
Basically I want this query in through the rest API:
```
wp-json/wp/v2/books?meta_query[relation]=OR&meta_query[0][key]=arkivera&meta_query[0][value]=1&meta_query[0][compare]==
```
Ive tried several different custom fields but it will always return all post objects.
In my functions file I've added:
```

$valid_vars = array_merge( $valid_vars, array( 'meta_query') );
return $valid_vars;
}
add_filter( 'rest_query_vars', 'api_allow_meta_query' );
```
I tried finishing some documentation regarding this but couldn't, also most of the similar questions are not for wordpress 4.7 since filter[xxx] is removed. | You can write your own REST handler for custom queries if you want. In your case, the query can done by doing so:
```
// Register a REST route
add_action( 'rest_api_init', function () {
//Path to meta query route
register_rest_route( 'tchernitchenko/v2', '/my_meta_query/', array(
'methods' => 'GET',
'callback' => 'custom_meta_query'
) );
});
// Do the actual query and return the data
function custom_meta_query(){
if(isset($_GET['meta_query'])) {
$query = $_GET['meta_query'];
// Set the arguments based on our get parameters
$args = array (
'relation' => $query[0]['relation'],
array(
'key' => $query[0]['key'],
'value' => $query[0]['value'],
'compare' => '=',
),
);
// Run a custom query
$meta_query = new WP_Query($args);
if($meta_query->have_posts()) {
//Define and empty array
$data = array();
// Store each post's title in the array
while($meta_query->have_posts()) {
$meta_query->the_post();
$data[] = get_the_title();
}
// Return the data
return $data;
} else {
// If there is no post
return 'No post to show';
}
}
}
```
Now, all you have to do is to access:
```
wp-json/tchernitchenko/v2/my_meta_query?meta_query[relation]=OR&meta_query[0][key]=arkivera&meta_query[0][value]=1&meta_query[0][compare]==

Thanks!
EDIT: When I try my method I just get an error "Fatal error: Call to undefined function get\_header() in /home/besa/public\_html/about-us.php on line 10" | WordPress doesn't work that way. In WordPress, none of the posts or pages that you visit actually *exist* anywhere on the disk. The content is grabbed from database and then the template files are filled with them and sent to browser.
In your case, you should create a file name `about-us.php` instead of `about-us.html` and then include it in your template by using this:
```
get_template_part('path/to/this/file/about-us.php');
```
Now you will be able to create a page from admin panel and use this file as its template.
As for your questions about link... Again you shouldn't directly link to a PHP file, because it simply won't work. If you access a PHP file directly, it doesn't load WordPress's engine when it is loading.
To do so, you should use the slug. Create a page, write down its slug, and then create a dynamic link in your PHP template like this:
```
<?php echo site_url('/some-path/slug-goes-here'); ?>
```
The above function with append `/some-path/slug-goes-here` to your site's URL and output it, which would be your page's link. |
271,879 | <p>So this is what I'm fruitlessly trying to achieve - let's say there's a menu like the following...</p>
<p><a href="https://i.stack.imgur.com/yIbO2.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yIbO2.png" alt="enter image description here"></a></p>
<p>What I'd like to do is to generate a menu with just the title and the link of the current page the user is on and it's immediate children. For example let's say the user is currently on Sample Page - the menu should look like this...</p>
<p><a href="https://i.stack.imgur.com/FTgBk.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/FTgBk.png" alt="enter image description here"></a></p>
<p>If the user is currently viewing the Woo page, the generated menu should contain a link to the Woo page and it's children (Shop, Cart, Checkout, My Account). If the page the user is viewing has no children like on Yet Another Page, it should only display a link to the page the user is currently on (Yet Another Page in this case).</p>
<p>Is something like this possible to achieve? If so, how can I do this? Any tips would be greatly appreciated and thank you in advance.</p>

| So this is what I'm fruitlessly trying to achieve - let's say there's a menu like the following...
[](https://i.stack.imgur.com/yIbO2.png)
What I'd like to do is to generate a menu with just the title and the link of the current page the user is on and it's immediate children. For example let's say the user is currently on Sample Page - the menu should look like this...
[](https://i.stack.imgur.com/FTgBk.png)
If the user is currently viewing the Woo page, the generated menu should contain a link to the Woo page and it's children (Shop, Cart, Checkout, My Account). If the page the user is viewing has no children like on Yet Another Page, it should only display a link to the page the user is currently on (Yet Another Page in this case).
Is something like this possible to achieve? If so, how can I do this? Any tips would be greatly appreciated and thank you in advance. | WordPress doesn't work that way. In WordPress, none of the posts or pages that you visit actually *exist* anywhere on the disk. The content is grabbed from database and then the template files are filled with them and sent to browser.
In your case, you should create a file name `about-us.php` instead of `about-us.html` and then include it in your template by using this:
```
get_template_part('path/to/this/file/about-us.php');
```
Now you will be able to create a page from admin panel and use this file as its template.
As for your questions about link... Again you shouldn't directly link to a PHP file, because it simply won't work. If you access a PHP file directly, it doesn't load WordPress's engine when it is loading.
To do so, you should use the slug. Create a page, write down its slug, and then create a dynamic link in your PHP template like this:
```
<?php echo site_url('/some-path/slug-goes-here'); ?>
```
The above function with append `/some-path/slug-goes-here` to your site's URL and output it, which would be your page's link. |

But you have more possibilities. For instance <a href=\"https://codex.wordpress.org/Function_Reference/is_404\" rel=\"nofollow noreferrer\">testing for 404</a> pages and defining a background image for that, insert a certain background if there is none, do different things for different category pages and so on.

| So, I'm totally new to WordPress and trying to "convert" a static site to a WP theme.
I have a page where I'd like to use the featured image as a background for a div.
I was wondering what is the best way or whats the convention to do that?
It doesn't matter if its a featured image or whatever, I just want the user to be able to change the image from the dashboard.
I'd shy away from inlining if possible, so is that the only option? | There's two possible options in creating a stylesheet from a dynamically generated value. The first options is **Inline stylesheet**, as follows:
```
<div id="hero"
style="background-image: url(<?php // TODO retrieve image here. ?>); ">
</div>
```
And the second options is to use an **Internal stylesheet**, and possibly the best solution out of both. Using stylesheet internally requires you to have your `div` an identifier possibly assigning the *ID*, or *class*, code as follows:
```
<div id="hero"></div>
```
The **Internal stylesheet**:
```
<style>
#hero {
background-image: url('<?php // TODO retrieve image here. ?>');
background-position: 50% 50%;
background-size: cover;
}
</style>
```
Using **External stylesheet** to retrieve and assign the value of the image from the database is impossible. You can still use external stylesheet for the rest of the styles of your `div`; i.e. `#hero`, and have the image be retrieve and assign via inline/internal stylesheet. |

271,968 | <p>I have been struggling with an archive template for a custom post type. I want to display the posts grouped alphabetically by a custom taxonomy called countryname. I tried more than half a dozen examples and finally found one that almost works.</p>
<p>Here is my code so far. When I get this working I will pull in the postmeta, but for now I'd be happy just getting the titles under the correct country.</p>

- a post
- another post
England
- this post
United States

- a post
- a post

| I have been struggling with an archive template for a custom post type. I want to display the posts grouped alphabetically by a custom taxonomy called countryname. I tried more than half a dozen examples and finally found one that almost works.
Here is my code so far. When I get this working I will pull in the postmeta, but for now I'd be happy just getting the titles under the correct country.
What I want will look something like this
```
Canada
- a post
- another post
England
- this post
United States
- short post
- some post
- that post
```
But right now it looks like this:
```
Canada
- a post
- a post
England
- a post
United States
- a post
- a post
- a post
```
I added wp\_reset\_postdata() But that didn't work either. Can someone help me troubleshoot this? It seems that the problem must be in the query to return each custom post within this taxonomy category.
Thank you!
```
$taxonomy = array( "name" => 'countryname' , "slug" => 'countryname');
$custom_post_type = "tours";
if ( have_posts() )
the_post();
?>
<?php
// Query your specified taxonomy to get, in order, each category
$categories = get_terms($taxonomy['name'], 'orderby=title');
foreach( $categories as $category ) {
?>
<div id="content">
<h2 class="page-title">
<?php echo $category->name; ?>
</h2>
<?php
// Setup query to return each custom post within this taxonomy category
$o_queried_posts = get_posts(array(
'nopaging' => true,
'post_type' => $custom_post_type,
'taxonomy' => $category->taxonomy,
'term' => $category->slug,
));
?>
<div id='archive-content'>
<?php
// Loop through each custom post type
foreach($o_queried_posts as $o_post) {
?>
<div id="post-<?php the_ID(); ?>">
<h2 class="entry-title"><?php the_title(); ?></h2>
</div><!-- #post -->
<?php wp_reset_postdata();
} // foreach($o_queried_posts as $o_post)
?>
</div> <!-- archive-content -->
</div> <!-- #content -->
<?php } // foreach( $categories as $category )
``` | You're almost there. Since `the_title` inside your custom loop is one of the *Post template tags* you need to assign the global `$post` to use the new data from the custom query.
```
<?php
global $post; // Access the global $post object.
// Setup query to return each custom post within this taxonomy category
$o_queried_posts = get_posts(array(
'nopaging' => true,
'post_type' => $custom_post_type,
'taxonomy' => $category->taxonomy,
'term' => $category->slug,
));
?>
<div id='archive-content'>
<?php
// Loop through each custom post type
foreach($o_queried_posts as $post) :
setup_postdata($post); // setup post data to use the Post template tags. ?>
<div id="post-<?php the_ID(); ?>">
<h2 class="entry-title"><?php the_title(); ?></h2>
</div><!-- #post -->
<?php endforeach; wp_reset_postdata(); ?>
</div> <!-- archive-content -->

The thing is as you can see he is only fetching the posts from 2015. If you don't have any posts with the **publish date from 2015** you will get nothing, but if you want to grab all posts **from two years ago until the current year** you have to do the following:
```
$args = array(
'post_type' => 'project',
'posts_per_page' => -1,
'orderby' => 'title',
'order' => 'ASC',
'date_query' => array(
array(
'after' => date('Y')-2 . ' year ago'
)
),
);
```

| I want to run a **function A()** when a post is published and **function B()** when the same post is edited or updated.
For this, I found *publish\_post* action which is triggered whenever a post is published, or if it is edited and the status is changed to publish.
How can I use this *publish\_post* action to know that post has been edited or updated so that I can run **function B()**? | With the `post_updated` hook you can trigger an action when the post is updated. He passes 3 parameters:
* `$post_ID` (the post ID),
* `$post_after`(the post object after the edit),
* `$post_before` (the post object before the edit)
Here's an example:
```
<?php
function check_values($post_ID, $post_after, $post_before){
echo 'Post ID:';
var_dump($post_ID);
echo 'Post Object AFTER update:';
var_dump($post_after);
echo 'Post Object BEFORE update:';
var_dump($post_before);
}
add_action( 'post_updated', 'check_values', 10, 3 ); //don't forget the last argument to allow all three arguments of the function
?>
```
