Hook inside a hook
I'm hooking into `the_editor_content` to add a signature to new posts. However, when a user edits their post the content is lost and replaced with the signature.
I tried something like the following in the hopes that the `the_editor_content` would only fire for new posts:
add_action( 'new_to_publish', 'my_new_post');
function my_new_post( $post ) {
function my_editor_content( $content ) {
$current_user = wp_get_current_user();
$author_name = $current_user->display_name;
$editor_content = '<br><br><br><br><br>--<br>'.$author_name;
return $editor_content;
}
add_filter( 'the_editor_content', 'my_editor_content', 'tinymce' );
}
But it isn't working, I don't get the signature for new posts or any posts. Can this even be done this way? Note that `my_editor_content` works fine by itself.
Thanks in advance. | I went with a different approach to solve this (probably not the cleanest one but it works for me).
I parsed the current url and added the signature with `the_editor_content` if on the page for new posts.
If on the page for editing posts, I parsed the url again to get the post id and return the post content in the editor.
I have frontend posting forms so it works. | stackexchange-wordpress | {

How to pass data to wordpress page (without GET parameter)
I've made a custom page for my wordpress website which will return custom results based on the data in the URL (not a search page).
Here's what it does:
The url is something like ` while landing on the page, it is supposed to read the last part (which is BlaBla) and return results based upon that.
But i'm getting a 404 error page every time. However i can use a query like ` and do the trick, but i want the link to have a structure like the 1st one.
Is it possible to achieve this? Any help is appreciated. | It's completely possible to achieve this by using custom rewrite rules. Right now I don't have the opportunity to give you the actual code for it, but you can check the documentation for add_rewrite_rule() in the Codex. It's pretty straightforward if you add a custom parameter to the rewritten URL.
Actually, you already have the almost exact parameters for the function in your question. | stackexchange-wordpress | {

Entity to store contact form entries?
Lets say I develop minimal contact form plugin. The plugin save contact entries in the website.
I think custom post type is not best way to store contact entries since post type is specifically created for front-facing contents.
* * *
Because of this curiosity, I installed a form builder (FormCraft) and make one entry by filling the form. The entry saved and accessible from admin, but no custom post type created. (I guess many other form builder also similar).
I wonder what type of entity contact form use? | Post types are not only intended for front-facing content, they can be generic content objects you can use for lots of purposes.
If you're concerned with data being exposed, there are a number of arguments available for controlling whether the items can be queried from the front end, appear in search, have UI for managing items, can be added to nav menus, etc.. You can hide a post type entirely- front and back end, and only expose it via your own plugin code.
The advantage to using a CPT is that you get the API along with it to help speed development of your plugin, and taxonomies and meta data can be used with it and similarly hidden.
Other plugins may use their own tables for storing data. You can use the `wpdb` class to do whatever database operations you need with custom tables and data. I recommend exploring if native objects can cover your needs first, but sometimes you just need your own tables, like if you want many-to-many relationships, or other complex structures. | stackexchange-wordpress | {

Template hierarchy: how to let category.php conditionally-load archive.php?
In Wordpress template chaining for categories, we have WP looking for:
category-slug.php → category-id.php → category.php → archive.php → index.php
Now, I'd like to make some tweaks in category.php, for instance insert some conditions over there, and if the condition is true, use a particular template (custom) otherwise continue processing the chain moving control as usual to archive.php
How can I achieve that? I guess I will have to create a category.php file in my child-theme folder, insert conditional statements, and?

wp-cli for Creating page-template
I've recently started using wp-cli to work on WordPress and starting to love it.
However, I'm curious about creating page templates using wp-cli. I haven't been able to find anything on it, does anyone if I can create a page template using wp-cli.
I found the `scaffold` command but that also doesn't have the option to create it.
Wouldn't it be nice, if wp-cli has that option too?
If it already does, then do please enlighten me. | wp-cli is not a development tool, it is a server admin tool, as such all the scaffold stuff there is.... for lack of better word, unneeded bloat. It is unlikely to reflect best practice, especially if your copy is old.
In the specific case of page templates, there is really nothing worth "scaffolding" the easiest way to create a new page template is to locate one in a theme, copy to a different file name, remove the code (or not, depending how drastic the new template will differ) and edit the template name in the header. Using wp-cli for this will probably take more time. | stackexchange-wordpress | {

WordPress sometimes adds this to links created by the visual inline link editor:

WordPress Multisite/Network - How to use a subdomain as main blog and subdomain for child sites
I want to set up a WordPress Multisite where the main admin/blog URL will be on a subdomain, like `admin.mydomain.com`, and then additional sites I create will also be subdomains under `mydomain.com`, such as `site1.mydomain.com`. Instead, in WordPress's Network Setup section, it only allows subdomains like `site1.admin.mydomain.com`. How can I have the main site be `admin.mydomain.com` and child sites be like `site1.mydomain.com`? | There's a couple of different ways that might work, but both rely on using Apache/NGINX directives.
# Method 1
Setup WordPress MS at mydomain.com, create an admin.mydomain.com site and then redirect mydomain.com to admin.mydomain.com. All additional sites would naturally be subdomains to mydomain.com.
# Method 2
This is basically the inverse of Method 1. You should be able to use a plugin, such as < (it hasn't been updated in a few years, but it still works for me), to map site1.admin.mydomain.com to site1.mydomain.com. The downside is that this will require a manual entry for each new site you add (although this probably could be automated). | stackexchange-wordpress | {

Add element to widgetpage
I am trying to figure out if it is possible to add elements to the widgetpage in WordPress' dashboard without editing the widgets.php core file. Is there a WordPress function or something else (maybe even a jQuery solution) that will get this done?

Is there anyone that knows if this is possible and give me some hint/help. | You can use @kudratullah's suggestion to hook into the widgets page. The downside is that this allows insertion of a piece of html only in one specific place. If that location is ok, use that solution.
Otherwise, there are two other possibilities.
The first is to use jquery. Examine the source to identify the html element where you want to add your image (let's say #wrap). Then append the node like this:
$( "#wrap" ).append( "<img src='....' />" );
The second is to use the css after pseudoclass like this:
#wrap:after {content:url('/path/to/mypic.jpg');}
Both style and script files need to be enqueued to the admin. | stackexchange-wordpress | {

Comma separated tax terms, with "and" before last item

Locally installing wordpress. Database problem

How to stop WordPress from automatically turning letters into small or capital
I'm managing a client website (I did not build it).
What's happening is that WordPress is automatically changing letters into capital/small. Happens in front-end only.

Protect Passwords in wp_users with stronger protection than MD5
I prefer a better and stronger kind of passwords for my wp sites. After watching below MD5 tube and reading hash plugins, I can not find a good solution for WP.
> Search hash plugins!
>
> Why not to use MD5 tube!
In phpmyadmin I only get MD5 and SHA1 what is to easy to hack as you can see in the tube.
But what is really a good protection for all passwords on WP sites? I can not find it. Do I have to add an extra code-string to all passwords like: **@9I_^2u@wB72 &_Äbõ**. This will make it very difficult to hack I think. | Password hashing/checking system in WP is _pluggable_ , which essentially means that it is designed to be replaceable with custom implementation. This isn't commonly done due to relying on defaults and compatibility. WP tries hard for backwards compat (such as with earliest single MD5 implementation) and portability (hashes from one WP install would work on another).
There are off–the–shelf solutions around that change hashing to a newer and more secure algorithms. At this time this is mostly considered `password_hash()` in PHP, which is designed to be future–proof. Algorithm used and salts are embedded in resulting hash, so you can keep moving to stronger algorithms in future, while being able to transparently verify older hashes.
From quick search roots/wp-password-bcrypt is one of such implementations. | stackexchange-wordpress | {

How would I get Wordpress to parse /mypage/area/value as /mypage/?area=value?

In any case, I would now like the URL to be like:
* <
* <
These URLs would be parsed as:
* <
* <
How would I go about getting Wordpress to parse /mypage/area/value as /mypage/?area=value? | `add_rewrite_rule` is very handy for this use, first add your custom rule for this:
add_action('init', function(){
return add_rewrite_rule(
'([^/]+)/area/([^/]+)/?$',
'index.php?pagename=$matches[1]&area=$matches[2]',
'top'
);
});
and you already registered the custom query variable, next is (because you're in development) go to `admin > settings > permalinks` and save settings to flush the rewrite rules.

Modify link options when hovering over post title

function my_custom_fonts() {
echo '<style>.row-actions span:last-child {display:none} </style>';
This will hide the link added by the plug-in. If the extra link is not the last one in the row, then you have to replace `:last-child` with `:nth-child(n)`, which `(n)` is the number of the element in the row, starting from 1. | stackexchange-wordpress | {

Who is responsible for data sanitization in WordPress development?
I am studying how to write more secure WordPress code by implementing validation, sanitization and data escaping wherever necessary. Validation and escaping makes perfect sense, but I am a little confused about sanitization.
If I use a function like `add_post_meta`, does this function do sanitization for me? What about `set_option` or other ones that interact with the database. I usually interact with the database via these functions. In which situations do I need to worry about sanitization myself? | Yes, WordPress will sanitise data on its way to the database, so long as you use the APIs.
If you're using the `wpdb` object however you'll need to use the `prepare` method to sanitise. I recommend against writing SQL queries as it bypasses object caches etc, but if you must write your own SQL, use `wpdb` to prepare and execute it
For calls such as `WP_Query`, `get_posts`, `add_post_meta` etc etc sanitisation occurs
Note that this is purely DB sanitisation, any additional sanitisation or validation you require, such as trimming trailing spaces, validation of URLs, stripping tags, escaping, etc, must all be done in your code | stackexchange-wordpress | {

How do I fit a function inside an opening and closing do_shortcode

WordPress theme directory naming
Suppose, I named my WordPress Theme folder as TrueLove. Look 'True' is in the uppercase 'T' and 'Love' is in 'L'.

Is it a bad idea to write audit/access/transaction log information directly to the filesystem?
In addition to some custom post types, my application has two custom tables in the WP database. I'd like to keep a record of all inserts/updates/deletes to these two tables.
This audit trail won't be front-ended, and it won't be used often. I'd like it in place for my own diagnostic purposes. The application will be installed at 5-10 sites, and I expect to see fewer than 10,000 of these actions per year at each site.
I'm considering these options:
1. a custom post type (with no post meta)
2. a custom table in the WP database
3. a simple append-only file in the filesystem
Option 3 seems simplest, and it avoids gunking up the WP DB with this non-critical data. But writing data directly to the filesystem seems wrong somehow, and it doesn't seem to be a common approach.
Are there strong reasons to choose options 1 or 2 instead of writing to the filesystem? | There is nothing wrong with writing logs to a file, you just need to make sure you create a special directory for it and add .htaccess that will prevent listing, and probably deny all access to it from the web.
There is nothing overly wrong with storing data in the DB provided you do it in its own table, but unless you need to be able to filter the data online, it is probably just pointless overhead (in the end, DBs store everything as files...).
The advantage of having a DB table is that it is easier to create it using the WP DB APIs, but it is much harder to extract the information if you need the full log. (you need to explicitly write the code to do that, might run into memory limitations, etc) | stackexchange-wordpress | {

Does balanceTags() provide any escaping / protection?
I'm just getting into WordPress and keep seeing sample code with balanceTags() used when echoing out a variable.
Am I right in thinking it does nothing in terms of output validation?
Thank you | Right, so it will simply do its best to close any unclosed tag - that's it. Nothing more.
As you can see if you look at the source code, all the function does is make sure to balance out the tags that might not be. It's also explained in the codex. ("force_balance_tags" is the real function that does the work; "balanceTags" defers to it if the options or attributes ask it to)

Plugin usage wordpress
I've a some questions about wordpress, I'am a new user of wordpress,
In a commercial website under wordpress, can I use a wordpress plugin under
GPLv2 ?
If a theme is under GPLv2 can I use it for a commercial client ?
I see that often plugins have a pro version, do I have to buy it?, Or can I
just use the free version?
thanks a lot
Best regards. | _In a commercial website under wordpress, can I use a wordpress plugin under GPLv2 ?_
Yep. Note that we're now up to GPLv3 and other variations. There are certain types of limitation to the so-called "copyleft" license, but they don't bear on the "normal" type of usage you're referring to. The Wikipedia entry looked pretty good to me, if you want details.
_If a theme is under GPLv2 can I use it for a commercial client ?_
See above.
_I see that often plugins have a pro version, do I have to buy it?, Or can I just use the free version?_
You only have to buy the pro version if you want whatever is available in or in relation to buying the pro version (like enhanced support or customization services or other offers). If the free version (at least the free version under whichever GPL from the WordPress Plugin Repository) suits you, then you can run with it. | stackexchange-wordpress | {

What hooks do I need to hook into to capture ever wp_user creation/change?
I have a wordpress site and I have an external database I need to keep updated with the user information.
Whenever a user is created, updated, or otherwise modified by something like an admin, I need to update the other database. I thought there would be one or two hooks I would need to hook into (user created + user updated), but now I see that there are more than just those two.
user_register
profile_update
edit_user_profile_update
Are there any that I am missing? Which hooks do I need to get the job done? Does anyone have any advice to code this up?
URLs: < < < | Those first 2 actions you linked to from the codex, `user_register` and `profile_update` should be exactly what you need.
`user_register` runs right after a user has successfully registered and gives you access to their $user_id which you can use to retrieve any user data you need, like name, email, etc.
add_action( 'user_register', 'wse_custom_register_action', 10, 1 );
function wse_custom_register_action( $user_id ) {
// send data to your external db/API
}
`profile_update` works exactly the same way, and gives you access to both the old user data and the new, updated user data.
I don't believe you would need `edit_user_profile_update` in this instance. | stackexchange-wordpress | {

Importing MariaDB into Mysql in Wordpress
VVV for Vagrant now comes with MariaDB by default.
If I work locally for developing a Wordpress site and then want to import the database to a production environment. Will the import be compatible or is this bad practices?
Thanks | While at the current point in time there is very little difference, and maybe no difference at all, this is a bad practice if your development environment supposed to replicate the server your code will run on.
There is just no point in forking a product without having the intention to change it, and the changes might be explicit as different toolset commands or SQL syntax changes, or hidden like better/worse performance for some queries.
For 99% of the wordpress oriented development it makes no difference, but it always sucks to discover your current specific project is in the 1% only when you are running into problems (which usually comes when you have no time to waste on such things). | stackexchange-wordpress | {

Plugin MySQL SELECT custom data and filter on user meta

WHERE some-condition
AND wp_usermeta.meta_key = 'flag'

_Can that variable be read by any page with a hook to the function?_
If the variable is declared as global, then yes.
_Can one page set the variable and another page read it?_
No, only one page is loaded per a loop. And each time you load a page the variable is "forgotten" unless you store it someplace. If you want to set variables, you'll need to use a WP function such as `update_option()` and `get_option()`. This stores the variable in the database. | stackexchange-wordpress | {

String replace Wordpress Site Title
I want to get rid of a dash '-' in my Wordpress site title on mobile. To do that, I want to place a span around the dash, something like the below.
**Desired Result**
<h1 class="site-title">My Site Title <span class="remove-mob">-</span> Is Great</h1>

**Current Code**
<h1 class="site-title"><?php bloginfo( 'name' ); ?></h1> | **Method 1**
You can do this using JavaScript.
First, add an id for your `h1` tag. I will use `mobId` here so your header tag will look like this:
<h1 class="site-title" id="mobId">My Site Title - Is Great</h1>
Then replace the hyphen with your desired code:
<script>
var myStr = document.getElementById("mobId").innerHTML;
var newStr = myStr.replace("-", "<span class='remove-mob'>-</span>");
document.getElementById("mobId").innerHTML = newStr;
</script>
It can be written shorter, but i wrote the full code so you know what's going on.
**Method 2**
Strip using php `str_replace()`:
<h1 class="site-title">
<?php echo str_replace("-","<span class='remove-mob'>-</span>", get_bloginfo('name')); ?>
</h1>
You can save `get_bloginfo();` in a variable and use that in the function instead, in case it happens to return an error because of quotes. | stackexchange-wordpress | {

To retrieve the original author of a post inside a loop, you can use `get_the_author();` to get the username of the author or `$post->post_author();` to get his/her user id. If you wish to get the revisor's username or id, you can use `the_modified_author();` or `get_the_modified_author();`.
**2-** In the back-end
If you want to have this result in the back-end (view the original author in the admin panel), you can use the following plugin made specifically for this purpose.

Change default URL path (/blog/) of blog posts

It was previously */blog/title-of-post (but now the /blog/ part is gone). | You can create any structure you want for this on the permalinks settings page in the dashboard.
To set it to your example of /blog/title-of-post

Plugin Development for registered users
I am new to plugin development for Wordpress but not new to software development.
This question is to get an idea of the "best practice" style for the following question.
I need to make a form only available to registered users, who ideally have a username that is a specific numbers-only is that they already would have. Ideally, the user would register with this id as their username, their email, name etc. After logging in, they would have access to a form that would be created by a plugin. When they submit the form, it would add data to a custom table created by the plugin. I've seen a lot of resources for managing tables in Wordpress, so that's not an issue.
Is there a members plugin that has an API that would allow me to track their id (username) when they submit the form? Should I use the default user capability? What would be the best practice for this situation?
Thanks | > only available to registered users
If the users are logged in, there have a username and ID to identifier. WordPress have functions to get this data, easy to use. You get as as example the user datas via `wp_get_current_user()` and only the ID of the logged in user via `get_current_user_id()`. The documentation of the functions is inside the codex, there have a lot of documentations about this topic, also examples. | stackexchange-wordpress | {

alt tags of the images are not saving/emtpy
When I try to add an alt tag of an image via the library in Wordpress the alt tag is not saving. After leaving and coming back to the library again the alt tag fields are empty.
I’ve tried the following solutions which did not fix this problem:
Remove and upload the images again Tried several plugins which overwrite the original alt tag Disabled the WP Smush plugin Checked the file permissions
I hope someone knows a possible solution.

Use Custiomizer to setup meta theme color tag
I am running into a little bit of a wall on how to achieve what I would like and could desperately use some help. My WordPress theme is built for the colors to be changed in Customizer, I have it fully functioning exactly as I need it to (Finally, JQuery Mobile doesn't interact the greatest).
Now I am running into one small issue, I am using the meta tag to define browser bar color on Android and Windows phone (Not Apple because they don't support custom colors) `<meta name="theme-color" content="#000000">` This is placed in the `<head>` section inside my header.php file. I would like to grab the color from one of my color options in Customizer and put it in replace of the #000000. | Depending on whether you store your customizer settings as mods or options (which you define with the type parameter when adding a setting) you can simply use `get_option` or `get_theme_mod` in your `header.php` like this:
echo '<meta name="theme-color" content="' . get_theme_mod('my_browser_bar_color','#000000') . '">';
This line tells to look for the mod and if it isn't there make the color black.
To make this work with js-driven live preview you will also have to add a piece of jquery that appends the line to the `<head>` tag. | stackexchange-wordpress | {

Get the number of posts from the current page results
I am trying to get the current number of posts that will be present in a page.
`$wp_query->found_posts` will give me the total number of posts in the loop.
`get_query_var( 'posts_per_page' )` will tell me the number of posts per page.
`get_query_var( 'paged' )` will give me the current page number.
`sticky posts` seem to not be included in the above.
I can do some maths trying to figure out in what page I am, retrieve the number of posts, and consider the sticky. I could also add a counter in the loop, but I am trying to get the number before the loop is applied in the template (front-end).
Is there some variable in the `$wp_query` that I am missing for this goal?
* * *
To make it clear this is an example: Total posts from the loop 22. Posts per page 10. 1 sticky post.
* Page 1 should give 11 (10 + 1 sticky).
* Page 2 should give 10.
* Page 3 should give 2. | I found the solution. I was looking for:
$wp_query->post_count

They won't appear if youmake a search of the kind `site:yourdomain.com`.

Performance impact of using functions in WordPress?
I have a website that generates lots of dynamic contents. I'm facing performance issues even on my localhost, on a Corei7 processor.
I've tried to disable every unnecessary plugin, and ran p3 performance profiler to see the results. The resulting charts show that most of the loading time is spent on WordPress's core (not plugins).
I'm using simple functions like `if()` and `bloginfo('name')` and call metadatas like `get_post_meta()` and `the_permalink()` a lot of times on my pages, one could say maybe up to 50 functions in each page.
These functions seem very simple, however i'm not sure how much impact do they have on loading time.
Is there a way to find out which parts of the page consume the most time? or is there a general guide to understand how much impact does these functions have on WordPress?
Thanks are in orders. | The overhead of PHP function as a mechanism is minimal. After all nearly everything going on is function calls. On a reasonable hardware you will have to ramp up function calls into thousands and tens of thousands to generate significant overhead (as opposed to doing same things with less function calls involved).
Worth noting that PHP profilers tend to overestimate the impact of function calls. Xdebug is especially eager to do that. More so just having Xdebug enabled can slow things down in environment heavy on function calls.
P3 profiler uses PHP ticks mechanism to profile, which is highly unreliable.
For any realistic outlook into performance you need to use a profiler that works on PHP engine level, such as Xdebug or Blackfire. In lack of such your performance troubleshooting options are very limited and basically amount to stuffing code with timers and ripping it apart until you figure out the slow part. | stackexchange-wordpress | {

If a WP install is hacked, can it spread to other domains on a server?
I have a managed server with several WP and non-WP sites, and code has been prepended to the content of all files (for all domains on the sever) which begin with a php command.
I'm wondering whether the cause was a vulnerability or password-guess in one WP install, or instead a guess of the ftp password or other reason. | > If a WP install is hacked, can it spread to other domains on a server?
Sorry to hear that.
WordPress security depends on a trust you have in plugins, themes, and the WordPress core itself.
If only a single PHP file is damaged, the whole web farm that runs WordPress can be damaged.
So the fair answer to your question is Yes.
In WordPress plugins and theme have the access privileges of the _web server process_ that runs the web server. | stackexchange-wordpress | {

Reset generated wp-config.php with wp-cli
I'm trying to dig into wp-cli and I can't find how to reset a config file I've created with the following command line (Note: I'm in the folder where I want the wordress to be installed):
$ wp core config --dbname=aaa --dbuser=bbb --dbpass=ccc --dbprefix=wp_ddd_
Success: Generated 'wp-config.php' file.
Apparently, file is created (even if I don't really understand where at the moement...). I've noticed that I had made a mistake in my parameters and when I wanted to relaunch the command, here is what I got:
$ wp core config --dbname=new_name --dbuser=bbb --dbpass=ccc --dbprefix=wp_ddd_
Error: The 'wp-config.php' file already exists.
How can I solve this and besides, Can someone explain me where this temporary config file is located?
Thanks ;) | > How can I solve this and besides, Can someone explain me where this temporary config file is located?
This will be generated in the WordPress root folder, the same from where you call the `wp-cli`.
Keep in mind you need to provide the correct username password and database name, else it will error.
If you error like:
> $ wp core config --dbname=new_name --dbuser=bbb --dbpass=ccc --dbprefix=wp_ddd_ Error: The 'wp-config.php' file already exists.
Then simple move that file like:
mv wp-config.php wp-config2.php

Wordpress logged in but no access to wp-admin
Using Apache 2.2, Wordpress 4.4, Better WP Security. I have logged in, can browse all pages on front-end, but when I try to access any link that is on wp-admin I get 404 page. I don't have any ideas left for this situation.
I've tried with no luck to:
* disable plugins, as just BWS, and all plugins
* delete/reset .htaccess,
* set all folders and files to 777
* looked into table itsec_lockout but there's no my IP address
* searched sql table itsec_log and what I get for my IP in log_data is `a:1:{s:12:"query_string";s:0:"";}`, what is that?
What is left to try? | You need to enable the error logging in WordPress from the `wp-config.php`
define( 'WP_DEBUG_LOG', true );
After that, you will probably get some feedback inside:
wp-content/debug.log
Above that, you can try to get the exact feedback you get from 404 page. Check the console in the inspector, and the response from te webserver.
curl -I
Looks like inside your theme you have some redirecting problem. Try to remove the plugins, the theme and to set the 2017-teen new theme to check if this is true.
I hope you will isolate the issue soon.
* * *
### What I suggest, you create the test environment somewhere and upgrade the website to the latest version of WordPress.

Change the background color of my theme widgets
On the Widget screen I would like widgets that I have created specifically for my theme to have a different background color, how can the be achieved. | Your widgets will get an ID based on the class name you specify. You can then write a CSS selector based on those values. Say that you prefix your widget classes with 'foo_', then you can select them with:

}
To add that to the admin pages add something like this to your functions.php:

background-color: red;

migrating wordpress, but getting some php parsing errors

Wordpress Rest API custom endpoint optional param
Is it possible to use `register_rest_route()` with optional parameters in url?
Let's say route is registered this way:
register_rest_route( 'api', '/animals/(?P<id>\d+)', [
'methods' => WP_REST_Server::READABLE,
'callback' => 'get_animals',
'args' => [
'id'
],
] );

I also tried declaring the route like below, but without success:
/animals/(?P<id>\d+)?
You can declare another route without the param or utilize GET params, but is there a way to do this already in the `register_rest_route()` ?
Thanks for your suggestions. | You should put the named parameters of the route regex into an optional capturing group:
register_rest_route( 'api', '/animals(?:/(?P<id>\d+))?', [
'methods' => WP_REST_Server::READABLE,
'callback' => 'get_animals',
'args' => [
'id'

How to share media between independent blogs?
Two blogs in different subdomains, but files on the same disk.
If I hard link some of the uploaded media one into the uploads directory of the other, will the media be available?
Or do I need to duplicate database records as well? | I'm afraid you'll also need to create the database records - that's how WP looks for media files, starting in the db. Those records then tell WP the local path to the media file.
But that means that if your web server has access to both sub domain folders on disk, you don't need to hard link anything - just create your media records in the second db using the first db's path values.
All that being said, I should point out sharing resources between subdomain is probably not wise: at some point in the future, it is very much possible one subdomain will move to another server... Then your shared paths won't work anymore. (My $.02)

Get posts with same meta value as current post

'author' => $authordata->ID,

'posts_per_page' => -1,
'meta_query' => array(
array(
'key' => 'stashkey',
'value' => $id,
'compare' => '=' )
)
) );
This works fine to get all posts who have a meta value which equals the same as the current post id - but I want to get it based on having the same meta value as the current post.
Thanks | You should first get the meta value for the current post, then use it to make another query.

'author' => $authordata->ID,

Is wp_read_audio_metadata() function deprecated?

When using that code I receive this error on the front end:

require_once( ABSPATH . 'wp-admin/includes/media.php' );
$audio_file_path = get_attached_file( 1821 ); // example attachment ID

How to create a array that contains all of the children slugs of a specific parent category

Excluding category from loop not working

'cat' => $exclude,
