Is it safe to call do_action and apply_filters for built-in hooks?
I am working on a plugin that needs to duplicate some built-in WordPress logic. (This logic can't be invoked with any built-in method, nor can it be hooked into independently.)
During this sequence of actions, WordPress's normal behavior is to call an action hook (`do_action('wp_login', ...)`) and a filter hook (`apply_filters('login_redirect', ...)`).
If they're invoked at points in time which correspond to when they would have been invoked in Core, is it safe (and acceptable practice) to invoke these built-in hooks directly from my plugin? Or is the risk too great that other developers who have hooked into this expect the action to be executed at a very specific time? | I think there is a difference here between `do_action` and `apply_filters`.
`do_action` usually triggers a global state change, either output, enqueuing of resource, initialization of modules, and such. This, like anything which infuance global state can result in surprising side effect when used out of context.
`apply_filters` OTOH behaves much more like a function call, and if written properly should return the same result whenever it is "called".
Still, the quality of plugins varies (just few hours ago someone asked about a "pro" plugin that uses `eval` :( ), so your implementation strategy will depend in the end on the coding skills some 5$/hr developer copy pasting snippets he finds around the internet. You will need proper testing against leading plugins to make sure that your code works with at least the leading ones. | stackexchange-wordpress | {

How to limit the number of Related Posts?

while (have_posts()) : the_post();

endwhile;
}
wp_reset_postdata();

But this get the entire loop of all posts on the website. I'm wondering, is there a way to limit this and display for example 10 posts? Thanks a lot. | You need the argument **post_per_page** to limit the posts.
Before your loop it should be something like this.
$args = array (
'post_type' => 'custom_post',
'posts_per_page' => '10',
);
$wp_query = new WP_Query( $args );
// your loop
if ( $wp_query ->have_posts() ) {
while (have_posts()) : the_post();
get_template_part( 'preview', get_post_format() );

How to log out everywhere else, destroy all sessions "all other devices"?
WordPress panel service "log out everywhere else" is doing a nice job. I want to use this as a function outside the panel.
**Screenshoot**
`.
It's not really abstracted in such a way that you can re-use it outside of AJAX, but if you copy the source into your own function, minus the JSON parts, then you could perform the same action yourself.
The key part is this bit, which will destroy all sessions for a given user ID:
$sessions = WP_Session_Tokens::get_instance( $user_id );
$sessions->destroy_all();
The rest of the function is just checking the user exists, checking permissions, and sending a JSON response. They might not be relevant for your use case, so the above might suffice. | stackexchange-wordpress | {

Unknown file php5fcgi.core
Does anyone know what a php5fcgi.core file is? I've installed WordFence on a site that I've recently become an admin for and am getting warnings for two instances of this file:
* Unknown file in WordPress core: wp-admin/php5fcgi.core
* Unknown file in WordPress core: wp-includes/js/tinymce/php5fcgi.core | *.core files are usually generated by the linux OS when an un handled exception crashes an application, and it include (hopefully) useful deugging information that can help you analyze the cause. From the name of the file it was probably generated from a php5fcgi.
But.... those files for sure should not be in your wordpress directory, so first go ahead and remove them from there. You should try to inspect one of them and make sure it is total gibrish and nothing that seems like any software code. Assuming it is not malicious, you should keep monitoring for their appearance, and if they do appear again, you should definitely look how to prevent them from appearing in the wordpress directories as they might include sensitive information. | stackexchange-wordpress | {

Additionally added URL params leading to "Invalid post type." in the Admin Panel

If I add a simple `functions.php` file like this answer suggests, it just inserts raw code into the page.
Is there any way I can just insert one line into the header without having to replicate all the header PHP code? Surely it can't be this hard. | You simply enqueue your stylesheet using the get_stylesheet_uri()

WooCommerce shop page orderby
Recently I found that, WooCommerce was removed the `Display` option from WooCommerce admin settings. So that, my shop page all products currently showing in ascending order. But, I want to show them in descending order. This means that I want to keep the new products above always. Now I am using the WooCommerce with version of 3.3.5 and the theme name is storefront.
TIA | WooCommerce have moved this setting to the WordPress Customizer. From your WordPress admin area, browse to: `Appearance -> Customise`
Then, from within the customiser, you can find the setting here: `WooCommerce -> Product Catalogue` and simply change the order under the option 'Default Product Sorting' | stackexchange-wordpress | {

WC displaying products from category

* product_cat
* product_category
* product_category_id
* cat
* cat_id
* category_id

Create page that is not deletable

}

thanks a lot! | There many ways to solve this kind or problem, and without more details about what it is you are trying to achieve, it is difficult to give you a precise answer. Keep in mind also that ACF is made to ease the creation and usage of custom posts/fields and not really a tool to build relationships between data constructs.

Here is a general approach that you can use,
1. create a custom post type called `calender_event` for example.
2. create another custom post type called `event_session`.
3. create a meta-field for the first post type called `calendar_event_sessions`.
4. Each time you create a a new post `event_session` assign it to an existing `calender_event` and store its post ID as an array into the field `calendar_event_sessions`. This also means that when a post is deleted you need to remove it from any `calender_event`. | stackexchange-wordpress | {

Specifically, if you replace the main query with a `query_posts` call or a `WP_Query`, that query won't take into account parameters passed via the URL unless explicitly passed through manually.
Instead, use the `pre_get_posts` filter to modify the main query, rather than creating a new query to replace it.This ensures any additional queries passed via the URL will also work, and reduces time spent querying the database significantly for a nice performance boost.
Additionally, if you already use `pre_get_posts`, setting the `post_type` will override the URL parameter, so you need to check for its existence | stackexchange-wordpress | {

WP REST API only returning partial list of users
Started working with the WP REST API for the first time. Our ultimate goal is to dynamically load UI elements based on which user is presently logged in.

The two being returned are both administrators, but so is one of the three that is missing.
What on Earth am I missing?? | After much reading I found the reason why all users are not returned with the straight-forward HTTP request for WP REST API:
This is a **non-authenticated** request, therefore only publicly available users data is released in a GET request.

WooCommerce Stripe Plugin not showing up in settings
This is probably a simple thing but I have tried installing the WooCommerce Stripe Gateway plugin but it's not showing up in my WooCommerce settings under checkout.
My Installed plugins -
![Plugins](
And under WooCommerce > Settings > Checkout -
![Checkout Options](
I have tried installing it by searching for it under plugins and manually importing the downloaded zip file but neither seem to make any difference.
I've also have enabled SSL as I'd read that also might be the issue but still no joy. | Stripe for WooCommerce requires a minimum PHP version of 5.6.0. If you are running a version prior to this then this will most likely be the cause of your problem. | stackexchange-wordpress | {

WooCommerce pay per photo upload
So the thing is, I want to develop a plugin that can do this integrated with WooCommerce:
One goes inside website, click to "buy a product" and then can uoload one or more photos, paying per photo uploaded?
The concept here will be a photo contest and people can submit multiple photos but they have to pay per photo that they upload.
In order to achieve this, I am thinking in counting each file uploaded and then increment the quantity on that product, so then I have a product with a certain price that is incremented in quantity each time one uploads a photo.
Any suggestions on how to accomplish this more efficiently?
EDIT:
Found this plugin that will suite this purpose, so I don't need to develop it on my own saving me time: WooCommerce Drag & Drop Uploader | Don't know about plugins, but if you develop it yourself, then the process might be to have a 'buy now' type button that people pay for, then, on completing the transaction, they are sent a special upload link with a query parameter in the URL that allows them to upload a file.
Your code would have to generate and store the special query parameter (random guid type of value), then (on loading that page) verify the parameter as being valid (and not being used before). On successful upload, the code would diasble (inactivate) that guid so it couldn't be used again.
You will have to figure out how to use transaction processing on PayPal (or whatever payment provider) so that your 'thanks for the order' page would generate the stored guid/parameter.

How can I list only custom shortcodes?
Wanting to list specific shortcodes I've added, rather than all shortcodes, can the code at How to list all active and specific shortcodes in wordpress can be adapted to show only shortcodes which contain a specific word? (The custom shortcodes I want to access each contain the same specific word.)
And, if so, how...
I've searched extensively on this, and haven't found anything (nor know enough to decide if it's possible). | The linked question shows you how to get all the shortcode tags in an array. So narrowing them down to specific ones is purely a PHP question. But the answer's simple enough.
Use `array_filter()` on the array of tags with a callback function that uses `strpos()` to see if each tag contains the work you're looking for. Since the shortcode tag is the _key_ in the array, use `ARRAY_FILTER_USE_KEY` to use the actual shortcode tag for the comparison in the callback function:
global $shortcode_tags;
$shortcodes = array_filter(
$shortcode_tags,
function( $shortcode_tag ) {
return strpos( $shortcode_tag, 'woocommerce' ) !== false;
},
ARRAY_FILTER_USE_KEY
);
In that example `$shortcodes` will now be all the shortcodes from `global $shortcode_tags;` that contain the word "woocommerce". | stackexchange-wordpress | {

Detect change to user_meta and retrieve old and new values

Tips and suggestions for WP intranet extranet set up
I have my main WP site on my .com but I'm looking to have a separate WordPress installation for an intranet/extranet — essentially a library to keep internal information. I just plan on writing notes in Posts or along those lines.
Is it better to set it up on a subdomain vs subfolder? Does it matter? Should the main domain be a multisite and have the intranet a site off of that?
What are some options for hiding the site to the public (as much as possible) and for those that have direct experience with this, do you have any tips?
I suppose I can make use of a membership plugin, which is the likely route I'll take, but are there any additional methods to add privacy for information protection?
Thank you! | Roughly, I'd set up a new WP instance, installing it on an internal server that is not visible to the 'outside', and protected from outside use via firewalls.
If the info is just for you, you can use htaccess rules to deny access to all but your own IP address. You'd probably want to restrict access to your local subnet as further protection. You could even password-protect (via htaccess) the root folder of the WP instance.
Then, strong passwords (and a user name that is not 'admin') with no other users allowed (if just for yourself).
If you need access from the 'outside' (as from home to the WP instance at work), you should set up secure VPN access, with perhaps access only allowed to your home IP. | stackexchange-wordpress | {

Child themes let you override templates, these are not templates, and use `require`/`include` to load.

**No**
Modifying plugins involves either forking them or extending them via actions and filters. As a result, replacing a plugin file in the way you propose is bad practice. Doing it via a child theme is even worse, but luckily that is not possible.

$post->ID, // The post ID you want metadata from
'_key_name', // The meta key name
true // Whether to attempt to unserialize or return the raw value.
);

How to make WordPress orderby work with post_excerpt column?

echo wp_playlist_shortcode( array(
'ids' => '7,8,9',
'order' => 'DESC',
'orderby' => 'post_excerpt',

if ($atts['orderby']=='excerpt' || $atts['orderby']=='post_excerpt') {
function cmp($a, $b) {
return strcmp($a["caption"], $b["caption"])*(-1);
}
usort($tracks, "cmp");
}
before `$data['tracks'] = $tracks;` line.
Basically after all tracks are generated into the `$tracks` array and before this array is passed to the final array `$data`, I intercepted the code and checked if `orderby` parameter is set to `excerpt` or `post_excerpt`. If true did a `usort` to sort array descendingly by using `caption` as criteria. In playlist context, WordPress refers to `excerpt` as `caption`. If you need to be sorted ascendingly remove the `*(-1)` within the `cmp` function.

For exaple if I install a plugin, it will be installed with `770` and `660` permissions, so I get a `403` error through the javascript console for all assets of the plugin.
Is there a way/plugin, to adjust persmissions to the files and folders to be created in the future, not just the existing ones?

Plugin error "array_key_exists(): The first argument should be either a string or an integer"
Checking the Query Monitor, it's throwing out this error,
> array_key_exists(): The first argument should be either a string or an integer
which relates to this function:
public function lsx_team_scporder_get_terms_orderby( $orderby, $args ) {
if ( is_admin() )
return $orderby;
$tags = $this->get_lsx_team_scporder_options_tags();
if ( ! isset( $args['taxonomy'] ) )
return $orderby;
$taxonomy = $args['taxonomy'];
if ( is_array( $taxonomy ) && count( $taxonomy ) == 1 )
$taxonomy = $taxonomy[0];
if ( ! array_key_exists($taxonomy, $tags ) )
return $orderby;
$orderby = 't.lsx_team_term_order';
return $orderby;
}
Why is it throwing out that error? | From the php manual the `array_key_exists()` function takes as first argument _"any value possible for an array index."_ , again looking up for arrays in the docs we can get that _"The key can either be an integer or a string. The value can be of any type."_ , which also corresponds to the error you see from the Query Monitor.
Meaning that the `$taxonomy` variable that is passing to the `array_key_exists()` is not either a string or integer.
You can debug the `$taxonomy` variable, by making a `var_dump($taxonomy);`.

Hosting my WordPress site out of a subdirectory
I'm currently hosting several WordPress sites on one host account with cPanel, each site with its own domain. Right now, each of my domains maps to a subdirectory on the server, except for the primary domain, which by default maps to the public_html directory directly.
Because of this, in my public_html folder, I have my primary domain's WP files mixed in with the add-on domain root folders, thus becoming a little confusing. I'd like to put my primary site's WP files into its own folder and host from that folder.
With add-on domains, I know I can select the folder to which they refer to, but I'm not familiar with how to change where the primary domain directs as its root directory.

Changing the argument of a function
This is part of a function in Woocommerce:
function woocommerce_breadcrumb( $args = array() ) {
$args = wp_parse_args( $args, apply_filters( 'woocommerce_breadcrumb_defaults', array(
'delimiter' => ' / ',
'wrap_before' => '<nav class="woocommerce-breadcrumb">',

'after' => '',
'home' => _x( 'Home', 'breadcrumb', 'woocommerce' ),
) ) );
//blah blah blah
}
I am wondering how I can change the "wrap_before" in my child-theme without touching the function itself. First I though it must be with apply_filter but it didn't look right.
I am certain that this question has been asked many times but I couldn't find the relevant keywords for that. | Try: (add to _functions.php_ of your theme)
add_filter( 'woocommerce_breadcrumb_defaults', 'wpse_woocommerce_breadcrumb_defaults' );
function wpse_woocommerce_breadcrumb_defaults( $args ) {
$args['wrap_before'] = '<nav class="woocommerce-breadcrumb my-class">';
$args['wrap_after'] = '</nav>';
return $args;
}
Or, copy:
_wp-content/plugins/woocommerce/templates/global/breadcrumb.php_
to
~~_wp-content/ **themes/your-theme** /templates/global/breadcrumb.php_~~
**UPDATE:** This is the correct path and not above: ( _thanks @mmm_ )
_wp-content/ **themes/your-theme/woocommerce** /global/breadcrumb.php_
and change the `echo $wrap_before;` and `echo $wrap_after;` to your liking..

Wordpress Images Not Showing When FTP
Could someone explain or show me a link to learn why when you ftp an image to `uploads/sites/<blog_id>/` folder it does not show in the image gallery? Image gallery as in the one you see all your images in.
I'm using multi site. I could not find any documentation on why. Im transferring large amount of images onto a new sever. | Uploading the image is only one part of the process. When you add media to your site via the Media Library, it's actually added as an `attachment`, a built-in post type that carries with it a bunch of metadata. Simply FTPing images into the appropriate directory doesn't create the associated `attachment` post or set any of the metadata.
A bit of quick Googling led me to the Add from Server plugin, which might do just what you need. | stackexchange-wordpress | {

Is there SEO or related limitations to using Custom Post Types instead of WPMU?
With regard to the structure of a multi language wordpress site, I read articles discussing the pros and cons of a subdomain based WPMU(wordpress multisite) or a subdirectory based WPMU or WMPL plugin etc?
What about using Custom Post Types? I can use one site and segregate each language into a particular Custom Post Type.
Is there any drawback with regard to google SEO or anyother thing I don't know yet?
For example, I noticed CPTs don't have their own category taxonomy or are not supposed to have that. Does that work well with google "localization"? (since it might seem that the different languages are mingled together and served from one site)
Thanks | Internal DB structure has nothing to do with SEO. SEO is all about front end content and URL structure, and while internal APIs can make some URL structures easier or harder to achieve there is no limitation at all about the front end.
This applies both to "normal" wordpress and multisite.

WP_Query: Query posts only if their access is restricted to logged user's role
So this is what I'm trying to do. I have some posts that are visible only to users with a certain role. I want to display them in a user's profile section, so they're immediately visible after they log-in. Let me underline it: I don't want to display ALL the posts that my user is allowed to see, but only those that are restricted to my user's role.
What I found and tried didn't solve my issue.
$q = new WP_Query(array( 'perm' => 'readable' ));
while ($q->have_posts()) : $q->the_post();
the_title();
endwhile;
Of course this does query all the accessible posts, which is not what I want. So, can I avoid creating a restricted category to solve this? | If posts are restricted to a specific role users are required to have, you must add some piece of metadata to the post. Else, WP won't know which posts you mean.
There's a standard box for adding metadata to your post (select 'custom fields' under 'screen option' in your edit screen), or you could create your own metabox or (easier) taxonomy. From your question I gather you already considered the latter option and thought it too cumbersome. But there's no way to escape putting some tag on the post telling the system which ones are meant for which type of user.
Once there is some metadata on the post, you can query for it. | stackexchange-wordpress | {

Return only top-level navigation items from a menu using wp_get_nav_menu_items
I have the following function in my project:

{
$locations = get_nav_menu_locations();
$menu = get_term($locations[$menu_location], 'nav_menu');

<?php foreach ($nav as $link): ?>
<a href="<?= $link->url ?>"><?= $link->title ?></a>
<?php endforeach; ?>
This currently returns all navigation items present in my menu - parent/top-level and sub navigation. I am wondering how to alter this to **exclude** all sub navigation items. I only want to display the parent/top-level items. | Let's take a look at `wp_get_nav_menu_items` code reference.
It takes two parameters:
* `$menu` \- (int|string|WP_Term) (Required) Menu ID, slug, name, or object,
* `$args` \- (array) (Optional) Arguments to pass to get_posts().
So we can use `get_posts` args in here... And if we want to get only top-level posts, then `post_parent` arg comes useful...
So something like this should do the trick:
function cr_get_menu_items($menu_location)
{
$locations = get_nav_menu_locations();
$menu = get_term($locations[$menu_location], 'nav_menu');
return wp_get_nav_menu_items($menu->term_id, array('post_parent' => 0));

how to add dynamic footer credit in Greatmag theme

Thanks | With out knowing the theme personally it's not easy to tell you exactly what you need to do. However, as @WebElaine has pointed out, the code you will need to change will most likely be in your themes `footer.php` file.
It's not recommended to edit themes directly and you should, instead, consider using a WordPress child theme - <
If you have a child theme setup and activated, you should then copy the `footer.php` file from your 'parent' theme to your child themes folder and edit the file where you want your copyright notice displayed.

What is the difference between the different ways of linking stylesheets
I'm only just learning WP theme development so this may be a very stupid question, but I have noticed there are different ways to link to the main stylesheet from the `index.php`:
<?php bloginfo('stylesheet_url');?>
<?php echo get_stylesheet_uri(); ?>
`Register` and `enqueue` styles via a function and `add_action` hook in `functions.php`.
These are the ones I have come across so far.
What is the difference between them? They seem to do the same thing to me but I have read that registering and enqueueing styles via `functions.php` is the preferred way. Why? | Enqueueing via your `functions.php` is by far preferable, because it allows WordPress to keep track of which styles are loaded and in which order. This matters, because when css statement are equivalent, the one that is loaded last will be applied to the page.
This may not matter too much when you are developing a simple theme all by yourself (as you're likely to do as a beginner), but once you want something more complex you'll see the benefits. For instance when you want to reuse your theme for a second site, you'll want to build a child theme to store the changes in. At that point you need the enqueuing system to control the order in which the style sheets from parent and child theme are loaded.
Also, when you want to load style sheets you got elsewhere (like font icons), the enqueuing system makes sure you don't run into conflicts with a plugin that might be loading the same stylesheet. | stackexchange-wordpress | {
