Gutenberg MediaUpload component with default gallery functionality?
I have seen a few tutorials around utilizing the MediaUpload component from below.
<
But none of them demonstrate it with the default gallery functionality that is common pre-Gutenberg. For example the ability to select multiple images and then be taken to a second screen where you can order and caption them. See attachments if further info is needed.
There is the **multiple** attribute which can be set to "true" or "add" but it doesn't toggle the second screen for ordering the items or captioning them.
![1st Screen](
![2nd Screen]( | It isn't documented but if we take a look to the gallery block, we see it passes an extra prop to the MediaUpload component.
Try to pass `gallery` as well as `multiple` to the component. | stackexchange-wordpress | {

Comments are in database, don't show up in WordPress backend or frontend
I am in the process of rescuing the content from a WordPress site with a bloated/damaged database. Everything has gone according to plan except for the comments. I can see that the 4000+ comments are indeed in the database's `wp_comments` table, and I verified that the IDs of the associated posts are correct, but none of them show up in the WordPress admin area or the front-end. I haven't been able to find where the issue lies.
Maybe someone in the community has an idea for a possible fix? Thanks.
Edit: to clarify, I already moved the content to a new database, the issue happens on the new WordPress installation. The comments were imported to the database when importing the posts through the export/import tool. | Ok, so after going over the database structure, I realized that for some reason all comments status on the table comment_approved had been set to post-trashed. Changing the value of that column to '1' made it all reappear. | stackexchange-wordpress | {

What is debug.log.old? It seems to take up a lot of space
what is debug.log.old (please see attached image). It seems to take up a lot of space. Is it necessary to delete it? Or should I leave it alone? Thanks![screenshot]( | It is not necessary to delete it but if you want to save your space then you can delete it. Actually when we turn on the debugger then debug.log file created.

Include a PHP file inside an array
I'm trying to add a custom PHP script inside of the nav menu (before the closing ) and struggling.
Code here:
<?php
wp_nav_menu(array(
'theme_location' => 'menu-1',
'menu_id' => 'primary-menu',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s<div class="my-div">' . $addCats . '</div></ul>'
));
$addCats = require_once('custom_menu_addon.php');
?>
The above code includes the file outside of the new added to the menu:
;
ob_start();
require 'custom_menu_addon.php';
$addCats = ob_get_clean();
wp_nav_menu(array(
'theme_location' => 'menu-1',
'menu_id' => 'primary-menu',
'items_wrap' => '<ul id="%1$s" class="%2$s">%3$s<div class="my-div">' . $addCats . '</div></ul>'
));

Custom Archive Template for Multiple Categories
I want to create a custom archive template for two post categories.
One of my categories is events, and the other one is courses (I have more). I already have a custom template for events (category-event.php), but I want to create another one to list both events and courses, but not include any other categories. The layout will be more or less the same as the category-event.php template. How can I do this? | The simplest way I can think of would be to have the two categories you want to display together grouped under a parent category.
Parent Category
|----Child Category A
|----Child Category B
The file category-parent-category.php would by default show posts from both. The file category-child-category-a.php would only show from a. The file category-child-category-b.php would only show from b. The file category.php would show from all categories.
Would that do what you want? | stackexchange-wordpress | {

How to check if a post has at least 2 terms from a custom taxonomy attached?
I have a custom taxonomy with several terms. I need to check if the post has more than 1 of these terms. How can it be done? | get_the_terms( int|object $post, string $taxonomy ).
Use the above function to get the terms of the taxonomy. It will return the array of terms associated with the post. Then you can use the php function
$count = count( $array ).

Integrate Gutenberg as a Standalone App
I'm thinking about integrating the new awesome WordPress block editor (Gutenberg) outside of its environment (WordPress core), so is there any way to get just the text editor code and use it for example in another CMS or framework or just a simple HTML page? | Yes, You can use Gutenberg as a standalone app or CMS agnostic app. Drupal using Gutenberg as a npm module and then integrating in their own CMS. Drupal Gutenberg is decoupling Gutenberg from WordPress and using as JS editor Gutenberg JS.

Number of Style for Image Added into Post
When adding an image through the GUI, an `HTML` element is created:
<img src="
alt="leaf graphic"
title="leaf graphic"
class="alignright size-medium wp-image-3109"
height="25" width="30"/>
A sequential `3109` and a style name `wp-image-3109` (?) is generated.
Besides, I cannot find it in any table in the DB (`wp_posts`, `wp_postmeta` or any other table). How the next ID must be generated? Is there a WP PHP function returning it?
Thanks in advance. | I’m not sure if I understand your question correctly, but...
In WP any attachment is a post (of attachment type). So 3109 is ID of that post.
This means, that if you’ll take a look at wp_posts table, then you should find that post and there should be some additional info stored as meta fields in wp_postmeta table (for example sizes of all generated images are stored as meta).
So the ID of next uploaded image will be the next value of ID column in wp_posts table. | stackexchange-wordpress | {

WordPress 5 WP REST routes - No errors
I'm using WP JSON to return JSON for certain routes.
Prior to WordPress 5, WP JSON would return PHP errors in the response, e.g. `Notice:xxx` or `Warning:xxx` when a PHP error was encountered. Since I upgraded to WordPress 5, such errors are supressed/ skipped and JSON is returned. Fatal errors return a 500 as expected.
I cannot find any documentation identifying why these errors are not being returned. And Google doesn't seem to be shedding any light. Does anybody know what's going on? Also, if it's "toggleable", does anyone know how to "turn errors on"?
PHP outputs errors to screen as usual elsewhere in WordPress. | REST API should always return JSON, so it’s output can be parsed as such. If it’ll return something that is not correct JSON, then your JS scripts may stop working.
This is why there should be no errors printed in these requests - such messages break JSON response and make it hard to parse.
And there was some code that was trying to prevent such messages from occurring, but it wasn’t working properly.
This was fixed in 5.0 in bug #44534.
You can always add this code to your method, id you're really (really really really) sure, what you're doing:
if ( true === WP_DEBUG ) @ini_set( 'display_errors', 1 );
PS. You should never display errors on production server - it’s compromising security of your site. Always use files as logging method. (It’s also easier) | stackexchange-wordpress | {

How to align full div
I want to align this **scrolling events** on the slider left to right but it's not working. Can anyone tell me the exact way to align it at the **right** side on the slider image using custom css?
.un-post-scroller {
position: absolute;
float: right;
} | The main issue you are running into is that you are targeting the wrong element. The parent of .un-post-scoller is what has a limited width aligned to the left, so you won't escape that easily.
Instead, target its parent. Unfortunately there is not a particularly clean candidate here since the parent is a generic grid system class (col-md-5). Usually you want to use the grid system's class to move things over -- in the case of Bootstrap, that would be offset-md-7 (or slightly different depending on your version and which grid system you use).
That requires modifying the actual HTML. Since you asked specifically for how to do it with CSS, you might try something like:
.header-overlay-scroller .col-md-5 {
float: right;
}
The header-overlay-scroller is just there so that not **all** .col-md-5 classes are targeted. | stackexchange-wordpress | {

Get count of custom post tags

return ( isset( $tagatts->count ) ) ? $tagatts->count : 0;
}
add_shortcode( 'tag_count', 'tag_count' );
And yes, I'm not a developer but I am trying to learn! :-) | why don't you try:
function tag_count( $tagatts ) {
$tagatts = get_terms(
array(

'hide_empty' => false,
)
);
$tagatts_count = count ( $tagatts );
return $tagatts_count;

require/include php file in add_menu()
I'm creating a custom WP Admin Bar menu item with custom HTML inside the dropdowns. Referring to this: <
the HTML i want to use is quite extensive so I created a separate php file for that HTML. Then I'm trying to include that PHP file inside the menu item, but it's not printing/echoing properly. Right now, all the shows inside the menu item is a 1, and the content is getting printed later on in the DOM of the page.
Here's the code I have:
$admin_bar->add_menu(
array(
'id' => 'dh_row_layouts-content',
'parent' => 'dh_row_layouts',
'meta' => array(
'class' => 'dh_hack',
'html' => include('docs/row_layouts.php'),
),
)
);
Any ideas? | You can turn on output buffering, `include` (and evaluate) the PHP file, and save the output (of the evaluated code) in a variable, like so:
ob_start();
include 'docs/row_layouts.php';
$html = ob_get_clean();
Then just use `'html' => $html` in the `meta` array when you call the `$admin_bar->add_menu()`.
Or if you _don't_ need to evaluate any PHP code in the file, you could use `file_get_contents()`:
'html' => file_get_contents( 'docs/row_layouts.php' )
And you may need to or better use a full absolute path. | stackexchange-wordpress | {

Detect if REST API is running

Plugin keeps saying needs to be updated and it's in a constant loop
I have a plugin that is on "Version 1.0"
When I update it (as indicated within my dashboard) it revers back to the same message.
The plugin is at "1.0" and the "update" is also at "1.0" so clearly there's an error or mismatch.
Question is: how do I remove the loop?
Thanks! | I'd just deactivate then uninstall then install again. Depending on the plugin, you might lose some customization or settings. But a lot of plugins don't remove anything they stored in the wp-options table (normally where plugin options are stored), so you may not lose any settings.
But I'd go to the plugins' support page. That's the best place for plugin support.
**Added**
Since the plugin support route didn't work, perhaps you can 'force' the plugin not to be checked for updates.
This question has some ways to do it: <
with this code (adjust for the plugin's folder):
add_filter('site_transient_update_plugins', 'remove_update_notification');
function remove_update_notification($value) {
unset($value->response[ plugin_basename(__FILE__) ]);
return $value;
}
Put that in the site's function.php (optimally in a Child Theme), or in a (possibly private) plugin of your own. | stackexchange-wordpress | {

<meta> in source code but I can't find it in files or plugins
I've got someone verified in my Google Search Console for our site and it's using a meta tag in the head.

register_activation_hook( __FILE__, 'myplugin_activation_callback' );
function myplugin_uninstall_callback(){

WordPress wp_nav_menu with a nav tag
I'm thinking about wrapping the `wp_nav_menu` with a nav tag instead of a div tag.
I've read at the WordPress codex that the container argument is only for using `ul` or `div`.
Do you guys know a way how to display the navigation in a nav tag so that the output looks like this:
<nav class="menu-header-menue-container">
<ul id="menu-header-menue" class="menu">
<li id="menu-item-86" class="menu-item menu-item-type-custom menu-item-object-custom menu-item-86"><a href="home"></a></li>
</ul>
</nav> | You were really close.
There is `container` argument for `wp_nav_menu`:
> **'container'** (string) Whether to wrap the ul, and what to wrap it with. Default 'div'.
Its default value is 'div', which means, that the `ul` will be wrapped with `div` tag. You can change it to `false` \- `ul` won't get wrapped at all in such case.
But you can also change it to `nav` \- and that is what you're looking. | stackexchange-wordpress | {

Page-parent field not appearing in editor
The drop-down of page parents doesn't appear in some sites as of upgrading to WordPress 5.0.+ | It seems the problem is with shortcodes, specifically if they echo any content - which of course they shouldn't. We had shortcodes registered to programmatically generate content on some pages on the front-end of the site but the functions the short-codes call appear to get called from the backend, even when creating a new page that doesn't call the shortcode, breaking the lazy-loading of that field.
As a quick fix I wrapped the function's content in a `is_page()` test and that seems to fix the problem:
`add_shortcode('my_shortcode_str', 'my_shortcode_fx');
function my_shortcode_fx() {
if (is_page()) {
/* only render on front-end, otherwise kills lazy load of page parent field in WP edit screen */
$content = /*something*/;
return $content;
} // ends is_page
}
`

You could probably modify that regex to only match `src` and `srcset` within an image tag but that's a bit more advanced than my regex skills will take us.

// The response should contain your special field HTML

WP Multisite: Are custom taxonomies specific to each site only?
I'm still trying to work out what Multisite does and doesn't do...
Are custom taxonomies specific to each site only or if I create a custom taxonomy on one site will others see it on another site? | Custom Taxonomies will be specific to each site.
If you were to create your custom taxonomies as a plugin, you could activate this plugin in all sites and all of them will have the custom taxonomies. BUT, even then, the data that you enter into each of the taxonomies will be unique to each site.
There might be a way to share them across your multisite network since all of your sites could share the same database. For this I'd recommend reading this article which explains a little more about how taxonomies and terms are stored in the database, and a possible way for you to do this. Personally I haven't tried this, but at the same time, I don't think it would be recommended, at least for most cases.

Override plugin class which has namespace

Using category and its sub-categories products attributes as filter in products pages
I have some categories and subcategories for each of them. And finally, some products under these subcategories.
What I want is to choose some attributes of these categories and subcategories products to show in products page as a search filter.

computers:
laptops
weight
color
pc
motherboard
casing-box

Detect if you're in the “Frontend Editor” mode in Visual Composer Wordpress

Archive: Lists itself
So I have created an archive.php, set everything up, and my archive page works fine.
Now I was wondering, of how I should prevent the archive page from listing itself.
When accessing the page called archive for instance < without any date/category parameters set, the query of the archive page is itself, like on a normal page. So the WP Loop will of course check has_posts etc. and the list itself, but I want to add something like the latest posts if there are no "filters" applied.
Anyone got an idea? | As @Milo told me in the comments, the problem lies in the fact, that the archive template shouldn't be applied to a page, but left untouched.

Category Page Template not Showing Posts
I am trying to get this template to work. | You should never create your own custom `WP_Query` queries on category templates (or any other archive template) and use them as main loop.
Why? Because it will break pagination. WordPress will still create all pagination links for such archives based on default query.
So if you want to modify the query in such way, that is should get all posts ordered by date, then you should use `pre_get_posts` action (add this to `functions.php` file):
function show_all_posts_on_category_archives( $query ) {
if ( ! is_admin() && is_category() && $query->is_main_query() ) {
$query->set( 'posts_per_page', -1 );
$query->set( 'orderby', 'date' ); // you shouldn't need this one - date is default value
}
}
add_action( 'pre_get_posts', 'show_all_posts_on_category_archives' );
And after using that code you can use typical loop in your template file:

Wordpress the_category(); only works with message-posts not with project posts, how do I specify project categories?

echo '<li>';the_category(); echo '</li>';
echo '<li>';the_field(Prijs); echo '</li>';
echo '</ul>';
endwhile; | `the_category` and `wp_list_categories` are for the `category` taxonomy term. What most people call a category is most likely a taxonomy. Category is just a default taxonomy for the `post` post type.
You need to use the general taxonomy functions such as the_terms and get_the_term_list.
echo '<li>'; echo get_the_term_list($post->ID, 'project_category'); echo '</li>';

Check if post is added manually or through wp_insert_post()
I might not be thinking this right but here is my situation:
* I have a custom post type called `events`.
* Some of my events are imported from an API and inserted through `wp_insert_post()` (in a plugin), some are added manually in the admin edit screen.
* On post saving I need to add some informations to the `post_meta` but **only if the post is added manually (through the admin edit screen)**.
So I am hooking into `save_post_events` and performing some security checks but I have no idea how to check if the request is only coming from the admin edit page because right now the `save_post` action triggers also if the post is added with the `wp_insert_post` function.
Any ideas?
Thanks | I have found a solution without adding any other metaboxes. I haven't thought about it but the import function in my plugin uses a `nonce` so I just check if my nonce is set or not.

Is <title> tag default in WordPress?
This may be a stupid questions but I have been building some themes. Some of them doesn't include the `<title>` in the head and some of the theme include it.
I belive some SEO plugin can add `<meta>` tag in the head but what about title?
So, is it because the SEO plugin or it is default by WordPress included in `wp_head()`? | Well, it's not a stupid question at all...
`wp_title` is a template tag and it was used for a long time (since 1.0.0) to put `<title>` tag in the header. This way plugins were able to modify the title with filters. In WP 4.4 it was about to be deprecated, but that idea was abandoned and you can still use that function.
On the other hand, you don't have to. Since WP 4.1 you can use `title-tag` theme feature instead.
So if your theme declares that it supports `title-tag` feature, then the title tag will be generated automatically and you don't have to put it manually in the header any more. And to declare that you're supporting such feature you need something like this in your code:
function theme_slug_setup() {
add_theme_support( 'title-tag' );
}

WPDB: how to get the value of a field in a custom database table
For my WordPress site, I would like to echo the value of a column in a row (determined by the user's ID) of a table in the database for my site. This table was created by a plugin so it is not accessible through the user meta. I have to try and get the value from the table created by the plugin.
For this example, the value is located in the "plugintable" table in the database and the column is "columnname". How get I get the value based on matching the user's ID with the "ID" row?
I've gotten here from the help of other online sources, but I'm stuck.
<?php
global $wpdb, $table_prefix;
$user_ID = get_current_user_id();
$value = $wpdb->get_var('SELECT columnname FROM '.$table_prefix.'plugintable WHERE ID = '.$user_ID);
echo $value;
?> | OK, so first of all, you should always use proper escaping, when building the queries.
This is how your code can look after fixing:
global $wpdb;
$value = $wpdb->get_var( $wpdb->prepare(
" SELECT column_name FROM {$wpdb->prefix}plugin_table WHERE ID = %d ",
get_current_user_id()
) );
The things you have to take care of:
1. You have to change `column_name` to proper column name you want to get.
2. You have to change `plugin_table` to proper table name you want to get the value from.
3. You have to change `ID` to proper name of column that stores the user id in given table. | stackexchange-wordpress | {

ACF not showing
I have a (weird) issue - can't get the ACF field to work on my page. I have a simple `text_field` and it shows on the `Homepage` page section:
ACF settings: : ;
/* tried also */
/* $hero = get_field('text_field'); */
echo '<h1>'.$hero.'</h1>';
?>
Where it shows the blank `<h1></h1>` on my page:
` function shows the value and it doesn't get/return anything. Like `the_title()` and other template tags starting with `the_`.
It means that:
This line prints the value and `$hero` variable is empty.
$hero = the_field('hero_title');
This line prints only `<h1>` tags.
echo '<h1>'.$hero.'</h1>';
What you want is:
echo '<h1>' . get_field('hero_title') . '</h1>'; | stackexchange-wordpress | {

Showing my server ip in source code for several links not for all links

Access WP_REST_Server from within plugin namespace
I am new to OOP and developing plugins. I have developed a plugin using the Plugin-Boilerplate with namespace. I expanded the boilerplate to include a REST folder and class so I could create custom routs/endpoints. It is working; however I cannot use the WP_REST_Server object. I get the following error: ..class-wp-rest-server.php does not exist.From my limited knowledge of oop my guess I it is not in my namespace. But how do I include/access it? My guess is there is a simple mechanism that is obvious to experienced OOPs. Thanks. | WordPress (version 5.0) doesn't use namespaces for it's classes, so try to use the global one:
\WP_REST_Server
to avoid assuming it's in your custom namespace.
One of the reason for this is that WordPress supports PHP 5.2.4+ that doesn't support namespaces. The minimum is PHP 5.3.3+, if I remember correctly, to support it.
Later this year (2019) WordPress plans to bump the minimum required PHP version to 5.6 and then to 7 at the end of the year. So after that, WordPress namespaces could be possible, but I'm not aware of any such planned changes though :-) | stackexchange-wordpress | {

Is a very simple theme secure enough?
I am very very new to Wordpress theme development and after creating one, I want to know if any threats will face it. There is no way i receive any data from visitors, including no comments received. There are no forms nor any plugins to receive any data.
What I want to know is if the theme I've created is secure enough to be used as a news website or not.
Thank you very much in advance. | If you follow the guidelines of the Codex for Themes (start here: < ), and ensure that any user-supplied input (if any) is sanitized, then a theme will be secure.
This also assumes that you have done basic security on your install. For instance:
* strong passwords on all accounts
* create an admin account without the 'admin' name
* take the first user account and demote it to subscriber (not an admin)
* strong passwords for your hosting account
* strong passwords for any FTP users on your hosting account
* keeping all plugins current/updated
* updating WordPress to current levels
* use latest PHP version on your site
Then your site will be less susceptible to attack. You'll also find lots of security guidelines via the googles. Look at them carefully and apply those that are needed. | stackexchange-wordpress | {

How to safely escape the title attribute
I'm going through some training on internationalization and escaping data. But I feel stuck with escaping the title attribute. I have the following code in a helper function...
echo '<h2 class="m-title">';
printf(
esc_html__('%s','tn'),
'<a href="'.esc_url(get_permalink()).'" title="'.the_title_attribute().'">
'. esc_html(get_the_title()).'
</a>
'
);
echo '</h2>';
Everything appears to be working fine with it, except the title attribute. The output looks like this....
Hello world! Hello world!
Because the DOM is loading the following:
<h2 class="m-title">
Hello world!
<a href=" title="">
Hello world!
</a>
</h2>
What I am doing wrong with calling `the_title_attribute()`? According to the docs, its already escaped.
Thanks for any tips! | Some screen readers read the title attribute plus the link text - so those visitors would hear "Hello world! Hello world!" - so unless your real title attribute is different than the link text and provides additional context to users of screen readers, you may wish to just not use the title attribute.
Or, you should be able to rewrite everything so that instead of echoing you have something like
<?php // your other code here ?>
<h2 class="m-title">
<a href="<?php echo esc_url(get_permalink()); ?>" title="<?php the_title_attribute(); ?>">
<?php the_title(); ?>
</a>
</h2>
This way you're mixing HTML and PHP but it allows you to immediately output both, so that `the_title_attribute()` is outputting in the right spot and not before everything else is parsed. You can add the additional `esc_html__()` call wrapped within each set of PHP tags but it's not clear why those would be needed for fields like `the_permalink()`. | stackexchange-wordpress | {

Please bare in mind that I'm passing on certain meta_queries and tax_queries which will make some queries to the database fairly hard on itself already.
Hope someone can help. | The easiest way to optimize this query would be to add `'fields' => 'ids'` to the arguments. This way only ids of posts will be retrieved from DB (and usually that’s a big change).

How to change posts order on Category and Tag archives?
WordPress by default order posts in descending order by date. But I want them to be in ascending order by date.
How do I turn the order to ascending only for tags and category? I don't want blog post orders to change. | You can use `pre_get_posts` action to modify this order. Here's the code:
function my_change_posts_order( $query ){
if ( ! is_admin() && ( is_category() || is_tag() ) && $query->is_main_query() ) {
$query->set( 'order', 'ASC' );
}
};
add_action( 'pre_get_posts', 'my_change_posts_order');
What we do here is:
1. We're adding our function that will modify params for WP_Queries
2. We make sure that it will change only main query (the one created by WordPress) and only on category and tag listings ( `is_category()` and `is_tag()`).
3. We change the order of posts for these pages by setting `order` to `ASC` | stackexchange-wordpress | {

Use custom field value as href
I created a custom field and would like to use its value as the href on a tag that would go on my footer.
The custom field is on the Settings > General area of the dashboard and I used add_settings_field() in order to create it.
So, for example, the value inserted in my custom field is "< and I would like that in my href. It would basically look like this:
<a href="CUSTOM FIELD VALUE GOES HERE">Click Here</a>
Is there any way to accomplish that? | To retrieve a value after using add_settings_field() you should use get_option().
So you could do something like this...
$value = esc_html(get_option('option_name'));
if ($value) {
echo '<a href="' . $value . '">Click Here</a>';
}
You just need to change `option_name` to your field name. The code will grab the value and if it isn't false echo the link. Also added the escaping.

Strange glyphs code error
Recently I've noticed that just above the web page logo, strange glyphs appeared. What might be the cause? How to get rid of these. | If there is anything printed above the logo, then in most cases it's caused by some errors in PHP. So somewhere in your theme or in one of plugins there is some bad code that is causing this.
And these characters suggest that they're some badly converted UTF characters or some other characters that are not supported by your font.
From my experience - such problem occurs when site gets infected and malicious code is working not entirely how its author wanted it to...

Get post count for current custom taxonomy
My site has a custom taxonomy called `series`. Underneath each post, I'm trying to display a specific div, but only if that post is in a series, and only if that series has more than one post. I feel like this should be possible with a simple if-statement, but I'm not sure how to evaluate the post count of the current post's first (because technically speaking one post could be in multiple series) `series` taxonomy.
Any help would be greatly appreciated! | You can use `wp_get_post_terms( get_the_ID(), 'series' )` to obtain all terms associated with the current post. This function returns array of `WP_Term` objects and `WP_Term` has `count` property which can be used as condition. | stackexchange-wordpress | {

How to load custom post archives sub-pages with ajax?
I'd like to keep the pagination links for /page/2/, /page/373/, etc but instead of changing the URL on the browser i want everything to load on the archive main page.
Ideally all those paginated URLs should redirect to the first page of the archive.
I don't want a "load more" button i want to keep the logic of pages but load them via ajax keeping url unchanged.
How can i do this? Any help is appreciated. | you might use the `$.load` and `preventDefault()` from jQuery.
Assugming that you have `.page-link` link class on each url in pagination and you have all the posts in the `#content` div following code can help you to load the posts in that div on that particular page.
$("body").on("click", "a.page-link", function(e) {
e.preventDefault();
$("#content").load($(this).attr("href") + " #content");
});
This will replace the current posts in that page with the new posts from that particular page. A look on your div structure might help me to write the complete code for you which can work on your site. | stackexchange-wordpress | {

WooCommerce subscriptions give option of manual renewal on checkout
I am trying to figure out how I can offer the option of manually renewing (automatic by default) a subscription on the checkout page. I would ideally like this to be a checkbox on the checkout page which is ticked by default saying 'automatically renew subscription'.
I can't seem to find any information on doing this so any input will be greatly appreciated. | Having done something similar recently:
Step 1: Add your checkbox as a custom checkout field (not covered here, you can easily find guides on how to do this).
Step 2: When the user submits their order at checkout, look for the manual renewal value in the submitted checkout data, and set it as meta on the WooCommerce order.
add_action('woocommerce_checkout_update_order_meta',function( $order_id) {
if(!empty($_POST['custom_manual_renewal'])){
update_post_meta($order_id,'custom_manual_renewal',1);
}
});
Step 3: When your subscription is created shortly after the order, look for your piece of meta and maybe set the subscription to manual.
add_action('woocommerce_checkout_subscription_created', function($subscription, $order){
if(get_post_meta($order->get_id(),'custom_manual_renewal',true)){
$subscription->update_manual(true); //set subscription to be manual renewal

Is it possible to access Gutenbergs reusable blocks in CPT block templates?
What I am trying to do is to use specific Reusable Blocks, that are editable by certain admins in the back end, within block templates for custom post types. So if you register a CTP or edit the capabilities of standard post types, you can use them like:
function create_add_post_types() {
register_post_type( 'product',
array(
'public' => true,
'capability_type' => 'page',
'show_in_rest' => true,
'template' => array(
array( 'core/heading', array(
'placeholder' => 'Füge eine Überschrift hinzu',
'content' => 'Projektname - Stadt, Land',
'level' => 1,
) ),
)
);
}
add_action( 'init', 'create_add_post_types' );
..except that insteadt of a core block like the heading here a reusable block is called. | I actually found a solution myself by following the way a reusable block is registered in this stackexchange thread:
Reusable blocks are all stored in/as **core/block** and this block has the attribute **ref** which carries the post id of that block.
So, you can use
array( 'core/block', array(
'ref' => [your block ID],
) ),
and the ID of every registered block is visible via the URL of that block at **[your-wordpress]/wp-admin/edit.php?post_type=wp_block** | stackexchange-wordpress | {

How it it possible to disbale all WooCommerce scripts and styles, but keep wc-ajax=get_refreshed_fragments working?

'src' => self::get_asset_url( 'assets/js/frontend/cart-fragments' . $suffix . '.js' ),

'version' => WC_VERSION,

Excerpt using Read More Tag
How do I get the excerpt of a post that is using a Read More Tag? The documentation states that I should use the `the_content` function, but I don't want that. I just want the text. Furthermore, I don't want the Read More link automatically inserted into the same `paragraph` tag - I just want the text, and I'll create my own Read More link. Essentially, I'm trying to print the excerpt of a post without the read more link. Can I do that? | You just need to set the first argument of `the_content()` to an empty string:
<?php the_content( '' ); ?>
If you don't pass an argument it will use the default, which is a link with the text "(more…)", but by passing an empty string, the empty string (i.e. nothing) gets displayed instead.
If you want it in a variable, use `get_the_content( '' )` in the same way, but for formatting to match properly you'll need to apply the `the_content` filter:
$excerpt = apply_filters( 'the_content', get_the_content( '' ) ); | stackexchange-wordpress | {

Get id from metabox dropdown
Im using Reusable Metaboxes (old but still works) and I created a metabox that allows the user to pick a post from a list of custom post types. Right now that works pretty well, I can see all the posts in a list and I pick one and save.
The data I see when I call the_meta() shows me that the field is indeed saving the id of the post I called:
episode_guestid: a:1:{i:0;s:2:"18";}
But I don't know how to get the id (in this case 18 - and this needs to be dynamic depending on the chosen post) and use it to display things from that post: title, featured image, metaboxes content.
Tried the "easiest one" with no success (so I will need help with figuring out how to display the metabox data from that post as well):
$guestid = $post_meta_data['episode_guestid'][0]; ?>
<h1> Featuring: <?php echo unserialize($guestid); ?> </h1>
Hope someone can help me out with this one. Thanks! | `the_meta` is a very bare-bones method. The return value you're seeing is raw, unserialized data. WordPress uses PHP serialization to store complex values like `Array`s and `Object`s as a `string` value. Have a look at `get_post_meta`:
$guest_id = get_post_meta( get_the_ID(), 'episode_guestid', true );
$guest_post = get_post( $guest_id[0] );
echo '<pre>';
print_r( $guest_post );

Redirecting Pages That No Longer Exist -- But Could in the Future
I have several 404 errors with a URL such as: myWebsite/tag/foo/page/4/. Page no longer exists because a few posts were deleted tagged as "foo." Which is better: 301 redirect that to myWebsite/tag/foo/page/1/? Or just 410 delete them?
I'm thinking if I do a 301 redirect -- then add more posts tagged as "foo," a 4th page will exist but those will be redirected back to page 1. Or if I 410 delete page 4 and it later exists in the future, it won't be found. I'm confused. | This is a tricky one.
The quick and dirty (but correct) solution is to use a `307` temporary redirect and then remove it when the page returns. This way your SEO will not suffer from the 404 errors and search engines will know that the page might come back.
However, if this is something that will happen often, it might be worth while looking at how the theme manages pagination and utilizing `wp_redirect()` to handle the redirect dynamically.
If you need help with the dynamic route please add a new question referencing your pagination setup. | stackexchange-wordpress | {

How can to use the players from the Media Widgets in the body of a post to play audio and video files
I've been trying to use the `<audio>` tag to play MP3 files and the `<video>` tag to play MP4 files, both with the `controls` attribute, and they work fine, but it isn't possible to apply custom styles over them and they change from one browser to another.
Basically, `<audio>` tag works like this:
<audio controls loop>
<source src="audio.mp3" type="audio/mpeg">
</audio>
And the `<video>` tag like this:
<video controls loop>
<source src="video.mp4" type="video/mp4">
</video>
So I realized the default audio player set to the new Media Widgets introduced in WordPress 4.8 have nice players and they could be enough and I'd like to borrow their properties to use inside the body of audio/video format posts.
How can I achieve that? | While writting this question, I went further to be sure I wasn't asking something trivial and it seems I was.
I realized the players of both the theme I used and those new WordPress widgets use the same `<div class>` called `.mejs-mediaelement` and then I realized it points to MediaElement.js indicated both in the Make WordPress blog post and the first Google result when we search for this name (I thought WordPress had its own workaround, but I was wrong).
However, we don't need to install the plugin because, as Jacob Peattie explained in a comment below:
> WordPress already has MediaElement.js built in and uses it for its audio and video players.
Then, we just need to add the following shortcodes respectively in order to add audio and video files to our posts:
`[audio src="mymedia.mp3"]`
`[video src="mymedia.mp4" width="640" height="360"]`
Then, it'll look just like the new Media Widgets because they do practically the same, but as a widget, of-course. | stackexchange-wordpress | {

Not sure what I am doing wrong here. | Actually your function works as you described.
I copied your function into a page template on my site without modifying it at all. I tested it with my main user, which has posted, and it said I had posted.
Then I created a dummy user that has not posted. I tested the same page and it said I had not posted. I also posted a post backdated more than 30 days, and it still said I had not posted within the last 30 days.
All of that is by design.
A couple of points to keep in mind:
* You aren't specifying in your query which type of post is being retrieved. Are you sure that the user you are testing with hasn't posted _any_ type of post? i.e. a custom post type, a page, a contact form via a plugin, etc.
* Your code is also always checking the currently logged in user. Make sure that's what you want. | stackexchange-wordpress | {
