WooCommerce - Hook after Loading Variation in Admin Edit page?
In Product's Edit page, when we click Variations, we will see AJAX loading for all of its variations.
Is there a Hook for when it finished?
I want to run a script to add some "at-a-glance" information on each Toggle Header. For example "Sold Out" label when the variation has 0 stock.
Thanks | In `woocommerce/includes/class-wc-ajax.php` there is a method on the `WC_AJAX` class responsible for loading variations called `load_variations`, it contains only one hook, which is a filter, named `woocommerce_ajax_admin_get_variations_args` which fires early in the method.
However if you are looking for something client side, then `woocommerce/assets/js/admin/meta-boxes-product-variation.js` triggers an event on the success callback of the `load_variations` function named `woocommerce_variations_loaded`.
Therefore if you are looking to fire subsequent actions using JS, then:
$(document).on('woocommerce_variations_loaded', function(event) {
//your code here...
});
Or you can try binding to the element in which the trigger is executed upon:
$('#woocommerce-product-data').on('woocommerce_variations_loaded', function(event) {
//your code here...

Woocommerce 404 after chang default language
After change default language in Woocommerce from Dutch to English I get 404 errors. I also have installed latest version of WPML. 3 Languages are active: EN - NL - DE. When I edit a link to open an category the link is as follow:
myshop.com/en/category/end-user/absorbin/ // result not ok
myshop.com/nl/category/end-user/absorbin/ // result ok
this results in a 404 error
when deleting /en/ string for default lang = EN the link works fine.
myshop.com/category/end-user/absorbin/ // result ok
Is there a possibility to prevent these 404 errors, instead of changing manually all the links in pages and so on? Maybe a rewrite rule in .htaccess

Can you navigate away from the updates screen during an update?
Bit of a _random_ question, I was running an update on a plugin, and went to `⌘` \+ **click** another item from the the dashboard menu, finger slipped and I ended up going straight to that page before the updates had finished.
I immediately went to the updates screen and the update had _gone_. I checked for updates just in case, but nothing. After looking in plugin changelog I can confirm it did update.
So my question is, do you have to sit through the update screen? Or is it enough to just "start the process" and you can click away to other pages on the dashboard. | Yes, server do not need any user input to complete the update, and once the request was received by the server it do not terminate it even if the connection to the browser had died (this is why it is actually impossible to cancel operations once started).

Wordpress subfolder installation AJAX Problem
I installed a Wordpress distribution in a subfolder. Everything works fine: The rewrite rules a correct and so on.
only my own private plug-in doesn't. I call per ajax the plug-in function via the url: /wp-content/plugins/plug-in-name/save_contribution.php
The absolute path is: <
I know that's not the proper way to do AJAX in WP but I can't change it right now. I will in future - I promise :-)
The interesting point is: When I call it, it loads: <
So it goes back to the root. And it finds it because I have a different distribution in my root with the same plugin - so it writes in the wrong database
Can someone help me one that?
And again, I will rewrite my plugin in future but now I have to solve that issue quite quick!

Why are many options missing from the editor?
I want to say for the record that I'm extremely new to anything related to Wordpress.
So my editor looks like this:

TED talk embedded videos cut off by sidebar
I've published a post on a new WP site which includes two TED talk videos. I used embed codes supported through the Jetpack plugin (e.g. [ted id=2252]). My problem is that the right edge of the videos (such as where the full-screen button would show) are being cut off by my blog's sidebar. I've tried looking through my theme's options and WP settings for a way to keep the videos sized properly so they don't conflict with the taskbar - but I can't find any such options.
I'm starting to reluctantly think I may have to dig into some CSS to fix this, but I'm not sure how to find the right file(s) or exactly what I'll need to add / edit. Any help would be appreciated. | _I remember when TED videos firstbrought me here to WPSE some time ago :-)_
The global _content width_ or the _embed size width_ option `embed_size_w` might be slightly off on your site.
Alternatively you could manually insert the _width_ :
[ted id="2252" width="600"]
where the _height_ is then adjusted to give you the `16x9` aspect ratio.

What is the impact if i ignore title and content in my custom post types CPT?
I am using CPTs (with PODS) and i need to "ignore" in "supports" the title and content.
I have no problem to alter the columns in the admin manage CPT list.
Also i understand that the standard functionality of WP that manages the content and title will not be there and i will have to manage my meta info in the various templates.
Other than that do i have any problem if i ignore them and leave them blank? | If you supply no title, WordPress will set the title to: (example)
## (no title)
This will be shown in the list table for the post type in the admin area, within the database, the `post_title` value will be empty.
## 1234
...where 1234 is the ID of the object. The `post_name` value in the database will receive the ID.
 for the `post_content` field, then your post will be set to `auto-draft` for the `post_status` column.
So you might need to use the `save_post` hook to set a default value for the `post_content` field. | stackexchange-wordpress | {

How to create an incremental list using shortcodes?

<p>John</p>
<p>Jack</p>
<p>Mary</p>

echo "<p>$name</p>";

Do I need to prepare query before get_results(), get_row() and get_var()?
I know that we don't need to use prepare($query) when we put it in insert() and update() because these functions sanitize data for us but I'm not sure if we need to prepare query before putting it in get_results(), get_row() and get_var()?
Thank you. | If your query has no dynamic input, then you technically do not need to use `$wpdb->prepare()`, however that assumes your own input is safe.
If your query contains parameters in which are dynamic, especially supplied by users from a form as an example, then you will want to use `$wpdb->prepare()`.
Using `$wpdb->prepare()` is just good practice, but in order to use it, you must pass at least two arguments (the query, and at least one placeholder).
> Please note: As of 3.5, wpdb::prepare() enforces a minimum of 2 arguments.

Media items hogging pretty permalinks
I have a WordPress installation setup but I'm having trouble with items uploaded to the media library taking up pretty permalinks. The only way to fix it that I've figured out so far is to delete the image from the library. However the image in question is used all over the site so I would much rather find another solution.
**Example:**
Say I upload an image called `foo.jpg` then make a page called `foo`, the pretty permalink for the page becomes `/foo-3`. If you try and change it, it reverts back to 3, unless you use something that isn't 'taken'. If I navigate to `url.com/foo` I get the attachment page for the image and not the page.
I've tried changing the permalink settings to all the different settings. I've also tried renaming the image 'title' but that is no good either.
Is there anything else I can do to force the permalink?
Thanks | It's not your permalink settings, it's the fact that `foo.jpg` was uploaded first and "stole" the slug `foo` \- you need to change it to something else, _then_ set your page slug.
Go to Media > `foo.jpg` > Edit (if you are in grid view, you need to go to "Edit more details")
 and set it something that isn't `foo`.
Now go re-save your page with slug `foo`. | stackexchange-wordpress | {

Wordpress Schema.org Markup. What value does it add?

In my opinion, using `WebPageElement` or one of its sub-types (like `WPHeader` etc.) is pointless for general web pages (there are some special cases and non-HTML contexts where it might make sense to use these types). It can even be hindering to have these types, because it’s not (easily) possible to provide content in `WPHeader`/`WPFooter`/`WPSideBar` as value for a property that should belong to the parent `WebPage` item (e.g., if your `WPFooter` contains a license statement, the `license` property would specify the license for the `WPFooter`, not for the `WebPage`).

How to remove Date from Meta Description on SERP?

To be more specific , i need to check for a condition when the user presses TRASH. If that condition is false then i need to stop the trashing action. If it is true it should continue. | Hook onto `trashed_post` and use `wp_untrash_post()` to reverse upon meeting a condition, pseudocode example...
add_action('trashed_post', 'wpse_218031_trashed_post');
function wpse_218031_trashed_post($post_id){
//use post_id to check conditions... if not met call:
if ( $some_condition ) {
wp_untrash_post($post_id);
}
}
`trashed_post` runs after `wp_trash_post` and after the post is moved to trash.
By the way, if the constant `EMPTY_TRASH_DAYS` is defined and is `false` posts will be permanently deleted and the subsequent hooks mentioned will not be fired, in which case `wp_delete_post()` will be called instead. | stackexchange-wordpress | {

How to set a header in wp_safe_remote_get()?
Previously I am using the below code. Now I need to change this code and replace `file_get_contents()` with `wp_safe_remote_get()`. I need to know how to set `'header' => "Accept: application/json"` in `wp_safe_remote_get()`:
$opts = array(
'http' => array(
'method' => "GET",
'header' => "Content-Type:application/json",
'header' => "Accept: application/json"
)
);
$context = stream_context_create($opts);
$file = file_get_contents(
'
false,
$context
);
I have tried to do this but not working
$args = array( 'timeout' => 30 , 'header' => "Accept: application/json");
$file = wp_safe_remote_get(' $args); | This will work
$args = array( 'headers' => array("Accept" => "application/json"));
$file = wp_safe_remote_get(' $args);

Developing a plugin where users can edit entries saved in database
it's the first time I'm writing a plugin. So far, it creates a table in database on activation, users can add entries to database and they can check saved entries.
I've added Edit and Delete links where I pass the id, but I don't want to edit entries on a different page. How to do it so it's on the same "environment"? Make it something like Users in WordPress, that kind of functionality? | I've managed to do it, but probably there is a much cleaner WP way of doing these things.
So, I have a menu page that I've added using add_menu_page. On it, I display all the records. The url is:
/wp-admin/admin.php?page=plugin-settings (or whatever you call it)
I use:
<a href="<?php echo bloginfo('url');?>/wp-admin/admin.php?page=utm-user-plugin-settings&id=<?php echo $row->id; ?>">Edit</a>
So basically, I ended up using the same page for my EDIT action by checking if $_GET["id"] is set or not.
Again, there is probably a better way to do this, I just don't know it yet, so this will do for now. | stackexchange-wordpress | {

Create Admin Only Taxonomies?
Is there a way to create admin-only taxonomies in wordpress?

variable endpoints for webservice

Wordpress has a trash for users? (Wrong result for count_user, greater than expected)

After some time, searching for errors in my code, I noticed that in the admin area there are 7 users listed, but near the 'All' link there is a number counting users and the number is effectively 9.

EDIT: Just for the sake of completeness, tried to delete an user and the total counter is correctly lowered by one unity. Still having two phantom users... | No, the user system does not have a trash (this is the default, obviously you can add pretty anything).

* Assumes role names are unique phrases.

Difference between fragment caching and wp_cache
I've been really confused about these two caching modes. What's the main difference between fragment caching and wp_cache? Can both of them be used hand in hand?
**EDIT**
I've read about the fragment caching found in the link commented by @Steven. I just want to know what's there difference and which one to use for better performance. | I'll post this as an answer, even though I don't know much about caching.
If you read about WP Object Cache it says:
> By default, the object cache is non-persistent. This means that data stored in the cache resides in memory only and only for the duration of the request. Cached data will not be stored persistently across page loads unless you install a persistent caching plugin.
From what I understand from the article by Ryan Burnette, you can set the caching time yourself.
> Fragment caching takes the output of a code block and stores it so for a predetermined amount of time. When the code runs, as long as the time limit hasn't elapsed, the block is ignored and the stored output is returned and printed onto the page.

Wordpress custom plugin that uses woocommerce enabled payment gateway for payment

Option #1 would be to add a subdomain to your existing domain and basically set up a landing page for that one product.

WP theme update causes child theme CSS problems

How should I avoid this problem in the future updates? | It may be possible that your theme author would be able to provide you with a previous version of the theme, not sure though. In regards to how you can avoid this issue in the future, I would recommend performing a backup of your Wordpress files before updating anything (this goes for plugin updates, Wordpress core updates, etc). There are a bunch of plugins out there that can help you with running automated or manual backups.
You could also set up a dev subdomain or recreate the site on a local environment and test any changes you want to make there before making them on your live site.
In any case, I would always recommend running scheduled backups of your site to ensure that you can always roll-back in case something goes wrong.

call get_header() function from different theme

My question is how to call `get_header()` from another theme? | You can't do it.
Well you can hack it, but it is very unlikely to give you the results you expect as there are usually many settings that needs to be initialized when themes are used and since themes are rarly designed to be able to "run" in parallel with other themes you will have a collision of settings. In addition the `header.php` contains more the the HTML header and the HTML it produce have to be compatible with the HTML and CSS produced by the other parts, something that it is unlikely to happen between different themes. | stackexchange-wordpress | {

Initial offset of number of posts in home page on the posts page

WP Media Uploader modal conflicts with Bootstrap modal
I was creating a form in a Bootstrap Modal to allow users to create new posts from the frontend. Everything seemed alright until I wanted to upload a file to the media library or choose one already uploaded:
This opens another modal using JS from the WordPress core. Unfortunately both BS and WP modals are using the same class on the body tag to indicate an opened modal: `modal-open`.

.bs-modal-open {
overflow: hidden;
}
.bs-modal-open .modal {
overflow-x: hidden;
overflow-y: auto;

.bs-modal-open {
@extend .modal-open;

$('body').addClass('bs-modal-open');

My page templates are currently built up as shown in first example but I really don't like that half of the template is _just sitting there_ , not being used and takes the server resources for no good reason.

Where to enqueue stylesheets for plugin?
I want to enqueue stylesheet to plugin I'm developing, like this:
function utm_user_scripts() {
$plugin_url = plugin_dir_url( __FILE__ );
wp_enqueue_style( 'style', $plugin_url . "/css/style.css");
}
add_action( 'wp_enqueue_scripts', 'utm_user_scripts' );
I am adding this code in the main file, [plugin_name].php.
Nothing is loaded, which part am I doing wrong? | Add this code in your main file: [plugin-name].php:
function utm_user_scripts() {
$plugin_url = plugin_dir_url( __FILE__ );
wp_enqueue_style( 'style', $plugin_url . "/css/style.css");
}
add_action( 'admin_print_styles', 'utm_user_scripts' );

Unified search across separate WordPress installations
I have many (100+) different WordPress installations across different servers and I'd need to have a centralized search... engine? to be able to search in all of the websites at once. I'm not running WordPress Multisite and installing it is not an option. Moving all the sites to the same server isn't an option either.
I've been researching for solutions and I've come across both ElasticSearch and Apache Solr, both seemingly built on top of Apache Lucene. There seems to be plugins for both systems, but none of them mention multi-website search.

Anchors in WordPress not followed/ indexed in sitemap.xml
Have anchor tags on a WordPress page about 300 on a page which are not listed in sitemap.xml, these links are generated dynamically. How do I index these?
Structure: A navigation link say **Games** when clicked --> Opens **List of Games (Football, Basketball etc.)** when clicked Football it opens --> Different versions of the games.
These are not listed in the sitemap.xml when created from online sitemap generators.
When clicked them manually in pages they open but doesn't appear in sitemap.
Any help would be great. Thanks! | Google does not index anchor tags, only URLs. (Note that by anchor tags, I assume you mean a URL like **site.com/page.html#anchor** )
The solution is to create a separate, static URL that displays the same content as what you would get with the anchor tag - for instance **site.com/page-anchor.html**.
Then you can just create a page with links to all these new URLs, and Google will follow those links nearly as efficiently as with a sitemap file. Or manually edit a sitemap.xml file and upload it to your server for Google to index. | stackexchange-wordpress | {

A question about register_activation hook
Looking at wp codex it says:
**The register_activation_hook function registers a plugin function to be run when the plugin is activated.**
I am finding this to be not entirely correct, for example i can activate a plugin that adds an extra field to WP registration form (using the add extra field example in codex) which does not require the register_activation_hook function (nor the register_deactivation_hook).
What codex does not tell you is when and when not to use the register_activation_hook, now i am going to guess that the hook is only required when including files for install or creating db tables on plugin activation, i would be grateful if someone who has more knowledge of WP and the correct use of the register/deregister hooks could clarify its correct usage.
regards | The `register_activation_hook()` is actually just a wrapper for `add_action('activate_' . $file, $function);` and is only executed when a plugin is activated.
This action/function is meant to be used by anything that should only execute once when the plugin is activated, things which would include stuff like
* adding custom terms to taxonomies
* create new database tables or rows
* running one time db processes which might include updating certain tables, columns or rows
* flush rewrite rules
On the opposite, `register_deactivation_hook()` only executes when a plugin is deactivated. This hook/function/action is meant for running processes to clean up after the plugin, which may include
* restoring db tables, row or columns which was altered
* removing custom db tables which was added by the plugin
* removing any custom options which was added by the plugin that would not be necessary anymore | stackexchange-wordpress | {

Several nonces?
Is there a point having several nonces? Does it increase the security?
_E.g adding nonces to meta boxes while`<form>` (which is basically the whole add/edit post screen) already has one by default._
* * *
* Docs, tutorials and old answers all insist adding nonce when you'll make a custom meta box
* Like I said, WordPress already adds a nonce to `<form>` by default
* Only I _(admin)_ has access to admin area, everybody else gets redirected
* I would prefer not to add nonce to every meta box codeblock - adding complicated meta boxes is **a huge amount of code** even without it
**How is it then?**
* * *
Optional bonus question: How about field sanitizing, validation? If nobody else has access.. | No, there isn't any point in that.
All docs relating to metaboxes are probably inspired from the wrong code at the codex which use a nonce.
The problem which nonces in metabox inadvertently solve is avoiding data corruption when the quick edit feature of the posts list page is used (or thinking about it any sort of external API as well), as at that point there is no metabox and no data in the form. This can be tricky especially if you have checkboxes in the meta box, but the better way to solve it is by having an explicit hidden input that will indicate that the metabox was displayed (basically this is what the nonce does but it is confusing as it has nothing to do with security).
As for sanitation and validation, you should always do it, because users can send bad values to your code which might even be a legal input. It helps with security but it is not the only reason you should do it - < | stackexchange-wordpress | {

How to tell which database tables belongs to which multisite site

Is there a better way to find out which tables belong to which site? | The number you refer to is the blog/site ID, so you have multiple methods of finding out which site it is:
* Look in the sites table, the number should match the ID, providing you with a URL and title
* Go to example.com/wp-admin/network/site-info.php?id= _insert-number-here_ and you'll be shown the network admin UI for that site

How to ignore wp_link_pages function?
I've bought a wordpress theme. I want to ignore all wp_link_pages functions from theme files. I will write my custom codes.
Is there any way to do it with functions.php | `wp_link_pages` has two filters you can use:
* The `wp_link_pages_args` filter is passed the `$args` for `wp_link_pages` so you could set `echo` to false.
* The `wp_link_pages` filter is passed the output so you could set the output to nil. Something like this should work:
/**
* Filter the HTML output of page links for paginated posts.
*
* @param string $output HTML output of paginated posts' page links.
* @param array $args An array of arguments.
* @return string $output HTML output of paginated posts' page links.

Why does get_template_part() break variables?
In PHP, when you `include` a file, the variables you're using in your current scope are available for use in the included file.
When using WordPress's `get_template_part()`, variables are no longer available in the "included" file.
`get_template_part()` calls `locate_template()` which then calls `load_template()`, which then performs the `require` or `require_once`.
If WordPress eventually calls PHP's `require`, why do the variables no longer work? Is it something to do with the 3 function calls before the actual `require`? | A script loaded within a function call will only work within the immediate scope of where `require` or `include` was used. So really only variables present when `load_template()` is called will be accessible to the loaded script (unless you use `global $myvar` of course).
The reason vars like `$post` and `$wp_query` are available to the script is because `load_template()` globals them in before loading the script.
If you wanted to make sure your script can access certain vars, either `global` them in or add them to the `$wp_query->query_vars` array before loading ( _not recommended but depending on the task it might be the only feasible option_ ), as those get extracted into the local scope before loading the script. | stackexchange-wordpress | {

Fatal error: Call to undefined function post_exists()

if ( ! is_admin() ) {

ACF check if variable has http, if else return string

How to increase execution time out limit in WordPress dashboard?

Custom Post Type within the Loop on Homepage (Page Template)
I'm trying to achieve something with the Loop and CPT. I've built a template page which will be the homepage of my website displaying articles and videos (the CPT). How can I add the CPT within a loop so it displays both in order as sort of a feed?
I've added the snippet below to `functions.php` :
// Custom loop feed
add_action( 'pre_get_posts', 'add_my_post_types_to_query' );
function add_my_post_types_to_query( $query ) {
if ( is_home() && $query->is_main_query() )
$query->set( 'post_type', array( 'post', 'videos' ) );
return $query;
}
And then put the code for the loop in my `homepage.php`.
Thing is, it displays it on my blog page, but on my homepage it made a post for the homepage.
` with `is_ftont_page()`. Read here for the difference between the two.
If that doesn't fix your issue, you could try making a call to WP_query from within your template code. It might look something like this:
$query = new WP_query(
array(
'post_type' => array('post', 'videos'),
'post_status' => 'publish',
'order' => 'ASC'
)
);
foreach ($query->posts as $post) {
// Your display code here.
}
There are a lot of parameters that you can modify to get the query working just the way you want it. It's all there in the documentation. If you go this route, you would want to remove the 'pre_get_posts' hook.

How to filter by date & a specific custom post type post-WP 4.4?
WordPress 4.4 introduced the ability to display date archives by appending /?post_type=custom_post_type to the end of the date url. i.e. localhost/2016/02/?post_type=news.
I had assumed I could do: `if( is_post_type_archive('news) && is_date())...`
But from what I can discern:
* is_date() will only detect if the page is displaying a year/month/day archive & is_date() applies to all CPT date archives as well
* is_archive() applies to all archive pages
* is_post_type_archive('CPT') will only apply to the archive page and filters out date archives
I'm trying to output a menu on the news date archive pages to display separately from the blog date archive pages. | There is no logical explanation why `if( is_post_type_archive('news) && is_date())` should fail and not work in your situation.
* `is_date()` return true on all date archives
* `is_post_type_archive( 'news' )` will return true on post type archives
When you visit `localhost/2016/02/?post_type=news`, both of those ring true, and they will only ring true on that specific URL
If it it fails, you have something breaking your main query, maybe a bad `pre_get_posts` action or you are using `query_posts` somewhere on the page which will break the main query object. You should do `var_dump( $wp_query )` and inspect the main query object. Specially look at `$query` property | stackexchange-wordpress | {

Password protected uploaded PDF page

PHP include statement not working?

Divert http to https with WordPress on IIS
I have a WordPress site **running on IIS**. The site has an associated SSL Certificate. Right now I am able to access the site with http and https.
How can I get my http to redirect to https?
Any help would be greatly appreciated.
Thank You | You'll need to update all of the URLs in your database to the HTTPS protocol:
1. Go and download Interconnect IT's Database Search & Replace Script here
2. Unzip the file and drop the folder where your WordPress is installed (the root) and rename the folder to **`replace`** (screenshot)
3. Navigate to the new folder you created in your browser (ex: ` and you will see the search/replace tool
4. In the " _search for…_ " and " _replace with…_ " fields:
* **Replace** : ` (non-HTTP)
* **With** : ` (HTTPS)
You can click the _dry run_ button under _actions_ to see what it will be replacing before you execute the script. Once you're done be sure to remove the `/replace/` folder.
Additionally, you can also look into using the Remove HTTP plugin which automatically scans your website and removes both HTTP and HTTPS protocols from your URL links. This will resolve mixed content warnings. | stackexchange-wordpress | {

How can I add an extra WooCommerce hook

Is it safe to change a Custom Post Type from "hierarchical:false" to "hierarchical:true"?
We have a Custom Post Type with contents on it, that always had its `hierarchical` setting set to `false`, and we'd like to change it so some new contents are organized as child of the old contents.
I don't know very well the intricacies behind the Custom Post Types, so I wondered if setting the `hierarchical` to `true`, would damage in some way the old contents?
I understand that SEO wouldn't be affected, because only new contents would acquire the new URL hierarchy, right?
Thanks for any hint, | Front end should be fine and would not affect anything, just make sure to flush your permalinks.
Your real issue will be in the back end. If you have a lot of posts, or planning to have plenty ( _hundreds ++_ ), making a post type hierarchical would be fatal. Because Wordpress builds trees for hierarchical post types in the back end, which is really expensive operations, you will get a fatal error due to memory exhausted or maximum time exceeded if you have hundreds or thousands of posts.
## EDIT
With the amount of posts that you are planning, you should be fine, although you will find that your back end page for that post type will load much slower. If you can live with that, well, yes, then you are good to go | stackexchange-wordpress | {
