jQuery does not work
I am working on a project where I need jQuery for. I added this to my functions, and the scripts are loaded in my header if I watch my page source, but jQuery doesn't work. What am I doing wrong?

How to get post content from an array of ids?
How do I get post content if I have an array of id's. Basically, I have a function that get post content if you provide an ID. but it doesn't work if I have an array of id's. My function is:
function get_post_by_id($id){
$post_content = get_post($id);
$content=$post_content->post_content;
return $content;
}
Now if I pass an id to this function it will work. For example:
$last_post = get_post_by_id(83);
print_r($last_post);
How do I get `post_content` if I have an array of `ID's`.Something like:
$last_post = get_post_by_id(array(83,80,92));
It doesn't work this way now. Please help! | If your first query works you can try something like this :
function get_post_by_id($id){
$content = array();
foreach ($id as $key => $value) {
$post_content = get_post($value);
$content[]=$post_content->post_content;
}
return $content;

Formatting Multiple add_theme_support Arguments
In my `functions.php` I have the following:
`add_theme_support( 'post-thumbnails', 'html5', array( 'comment-list', 'comment-form', 'search-form' ) );`
…which in WP 3.8.1 disables e.g. featured image (i.e. `post-thumbnails`).
My question is how to properly format all these support items in the `add_theme_support` function; is adding two separate function calls right or 'wrong'?
`add_theme_support( 'post-thumbnails' ); add_theme_support( 'html5', array( 'comment-list', 'comment-form', 'search-form' ) );` | You need to use one `add_theme_support()` call for each feature. Per the Codex, the proper function call is:

$wpdb prepare issue with mysql DATE_FORMAT
Today, I have a issue in $wpdb.
I used
$result = $wpdb->get_var(
$wpdb->prepare(
"SELECT DATE_FORMAT(report_date, '%d-%m-%Y') FROM table WHERE report_id = %d",
$report_id
)
);
The above code not works because of %d in DATE_FORMAT. How i solved this issue in wordpress | From the Codex page for the WPDB class:
> [...] the `prepare` method [...] supports both a `sprintf()`-like and `vsprintf()`-like syntax.
Having a look at PHP's documentation for `sprintf()`:

> // notice the double %%, this prints a literal '%' character
>
So you can use
$result = $wpdb->get_var(
$wpdb->prepare(
"SELECT DATE_FORMAT(report_date, '%%d-%%m-%%Y') FROM table WHERE report_id = %d",
$report_id
)
);

Difference between the 4 Built in RSS Feeds?
Can somebody give me an explanation on the differences between the 4 different built in RSS Feeds and why / when I should choose one over the other? Why does WordPress incorporate 4 different ones instead of focusing on 1 universal one? The feeds include:
1) RDF/RSS 1.0 feed
2) RSS 0.92 feed
3) RSS 2.0 feed
4) Atom feed

That means that even if WordPress _can_ generate 4 type of feed, that does not affect in any way performance, but gives the _possibility_ to users to choose a format they like according to reader they are using: is not WordPress fault if there are different types of feed standard.

Of course you, as a site owner, can decide to support only one version, it's as simple as:
add_action( 'pre_get_posts', function () {
if ( is_feed() && ! is_feed( 'rss2' ) ) { // only support rss2

Overwrite functions.php of a theme - What if the theme is updated?

Get ID of featured image using "get_post_thumbnail_id(the_ID())" - without printing to screen?
I'm using the code:
get_post_thumbnail_id(the_ID())
to get the ID of a post thumbnail image, but whenever I call this it outputs the ID to screen. I just want to get the value to use in another function, without it echoing anywhere.

get_the_title($postID) OR get_the_title()?

How to query_post custom posts within default taxonomy?

Create a page that automatically redirects to latest post of a specific tag/category?

else

Why do Wordpress rewriites seem to work differently for posts vs pages?
I am creating some simple rewrites in my functions.php file in my WordPress installation:
add_rewrite_rule('product1/faqs/?', 'index.php?name=product1-faqs', 'top');
I've noticed that if you hit "product1/faqs" in the browser, it successfully displays the content of "product1-faqs" but keeps the url as product1/faqs (which is desired) but only if it is a POST.

Why is that? I don't want have to limit ourselves just to posts for the sake of rewrites working as desired... | It's a pretty simple solution - WP_Query utilizes the `name` variable for posts and custom post type posts.

wp_get_attachment_image_src() width and height boolean

[1]=> bool(false)

Editing wp-config.php file asks for another installation
I edited wp-config.php and now I can't access my existing site and I see the Wordpress installation page! Help! How do I get to my existing site? | (s)FTP into your site, or use a file manager provided by your host, and undo what you did.
1. Then, if you were editing PHP with the built in editor as I suspect, _don't ever do that again-- ever_. It is like working on an airplane while it is in the air.
2. Create a local copy of your site and work locally. Upload to the host when you know the code works.
3. If you enable debugging, you should see clues as to where you went wrong, but you may not be able to do that in your case as it is the config file that is broken.

Troll the hackers by redirecting them
My website is getting somewhat popular, and with the it's increasing popularity there's an increase in the hackers.
Last night I visited my security logs and found that everyday approximately 10 people try to access
/?author=1
/?author=2
/?author=3
/?author=4
but I don't have any of these user IDs, so a 404 is generated to them. they also run a guessing bots on usernames:
admin
administrator
wordpress
Now, I want to troll them... so each time they try to access any of these two:
1. visiting /?author=1..etc
2. trying to login with admin username
I want their IP blocked off my site, and redirected to a youtube video.
I know the first one can be done with .htaccess trick, but can't quietly get this trick. the second one I guess is done by php, but I have no experience with Wordpress although I'm pretty good with PHP. | I understand this isn't exactly what you're looking for but these hackers are most likely bots and redirecting them won't matter at all.

Custom taxonomy only shows 0 in autocomplete for terms and "Choose from the most used tags"
I have a custom post type (`rezept` that I added a custom taxonomy `Allergiefrei` to. I got this working so far. Adding terms to the custom taxonomy's box works, too, but autocomplete and 'Choose from the most used tags' only shows "0".

function register_rezept_taxonomies() {
register_taxonomy(
'Allergiefrei',
'rezept',
array(
'label' => 'Allergien',
'rewrite' => array('slug' => 'allergien')
)
);

Different versions of Wordpress between local and production
First off, I am a WordPress newbie so please be gentle! :)
Long story short, I have been given a project in mid-flight. Development computer has Wordpress 3.8.1 setup with Microsoft Webmatrix. A purchased theme with customizations and content exists on this box. The client has an already purchased domain and hosting package from network solutions. Network solutions states they using Wordpress 3.5.1. When it comes to deploying from local to the web to the Network Solutions site, will I run into major pain points with the site being on a newer version? Maybe I'm being overly paranoid but I don't want to tell my developer to keep working on this site if we have to blow everything away and revert to an older version or work entirely online within Network Solutions.
**UPDATE: Network Solutions does allow you to upgrade Wordpress to the latest stable version which meant I didn't have to worry about this anymore.** | I would be very afraid to develop on 3.8.1 and try to run the same code on 3.5.1. Things have changed. 3.5.1 is ancient by web app standards. I can't say that I have ever tried to "backport" like that, but it does worry me. Much of your code would work. WordPress itself is pathologically backwards compatible, but if your code uses new features (intentionally or not) you will have trouble.
You can install an old WordPress on the development machine, but _3.5.1 is ancient_. It is unwise to run that on a production machine at all, much less to develop a site on it.
Additionally, with 3.5.1 you are likely to have numerous plugin and theme compatibility issues.
If Network Solutions won't update to a more current WordPress, and won't let you update, the smart move is to not use Network Solutions.
If that isn't possible, I would install the legacy WordPress on your development server and build to that. | stackexchange-wordpress | {

How to get raw unwritten querystring
Without permalink enabled, the urls look like ?p=1 and when permalink is activated it's the postname that appears... question .. isn't this a rewritten version of ?p=1 ..
When I use $_GET['p'], there is nothing in there... is that normal? | `$_GET` refers literally to `?p=1` part of URL. With pretty permalink if it's empty then there is nothing to access.
WordPress processed either case into query variables of `WP_Query` class. You should use `get_query_var()` to retrieve things like this, so in this specific case it would probably be `get_query_var( 'p' )`. | stackexchange-wordpress | {

Redirect after post deleted

Duplicate domain database to local - How?

Get rid of this Strict Standards warning
I'm trying to get rid of this warning from my wordpress installation. Strict Standards: Only variables should be passed by reference in xxxxx on line 67
The line with the "faulty code" is this one
$wp_theme_name = next(explode('/themes/', $stylesheet_directory_uri));
However, if I do pass the value per reference as requested, the WP doesn't load anymore.
Can you please help me to understand how to fix this?
Thanks Andrea | This occurs because you do the `explode()` call inside the `next()` call.

Is it possible to add a filter for the output of nav-menu items in admin?

For example, I want to remove the option to add a `title` attribute to menu items, only if the menu is used in 'position-x'.

$wpdb->get_var - What value is returned when zero records are found?

WHERE user_id = '$user_id' "));
if($queryPermission == NULL OR $queryPermission == 0) {
header ('location: noaccess.php');

}
When the SQL returns records the $queryPermission variable is set to 1 which is great. However when the SQL returns no records the variable $queryPermission returns nothing. I then want to try and pick up on this and redirect the user when that variable contains nothing.
I have tried "NULL" and "0" but neither of those seem to work. I was wondering, how can I pick up the case where nothing is returned by SQL using get_var?
Thanks :) | First, you're using prepare() wrong. Should be this:
`$wpdb->prepare("SELECT Active FROM testers WHERE user_id = %s", $user_id)`
Or even better (%d) represents numeric value as oppose to %s which is string:
`$wpdb->prepare("SELECT Active FROM testers WHERE user_id = %d", $user_id)`
If you have any debugging enabled, it will throw an error from your code. Which may make your location header not work properly.
Second, the get_var() function indeed returns `null` when there are no results.
Third, setting a location: header without actually exiting afterwards may cause your header to be overwritten by something else later. | stackexchange-wordpress | {

**I have a multiple word press installations that I am trying to reduce to one.**
Here is what it currently looks like:
Installation 1 = www.example.com
Installation 2 = www.example.com/foo
Installation 3 = www.example.com/foo/bar
How do I make it into one installation like this:
www.example.com/foo/bar
Where `/foo` and `/foo/bar` are two different pages.
Optionally: How do I do this:
www.example.com/baz/bar
Where `/baz` does not do anything (like a 404) and `/bar` is the actual content.
Thanks for the help! | You can create sub directories by making parent pages:
Say you want it like this:
example.com/topicnamebutnocontent/informationontopic
_Note:`/topicbutnoname` is a page/direcory that has no content._
* * *
You can create it this way:
* Make a blank page (it does not have to be blank) E.G. `topicnamebutnocontent`
* Make a page that you want to fill with your content E.G. `informationontopic`
* Set `informationontopic`'s parent page to the blank page E.G. `topicnamebutnocontent`
* Double check that the permalink/address is correct with what you want.
And that should create the directory structure that you want!

Multiple Conditions for Child Page Title
I've been trying to work with Conditional Tags and cannot wrap my head around this problem. PHP novice here.
On sub-pages I need to display the parent page title as well as the page title. I have it working with this:
<h1><?php echo get_the_title($post->post_parent);?></h1>
<h2><?php the_title(); ?></h2>
But the problem I have now is that on the parent pages the page title is displayed twice, as the parent page title and the page title. Instead, when on a parent page, I need the `h2` to display "Select a sub-page", if there are child pages...or display nothing, if there are no child pages. Something like this is what I'm thinking is possible:
<h1><?php echo get_the_title($post->post_parent);?></h1>
<h2>
<?php
if is_parent_page_without_children() {echo '';} ;
elseif is_parent_page_with_children() {echo 'select a sub-page';} ;
else the_title();
?>
</h2> | I found this in the Conditional Tags codex, section 2.12:
> "Note: There is no function to check if a page is a sub-page. We can get around the problem:
if ( is_page() && $post->post_parent > 0 ) {
echo "This is a child page";
}
So I've altered it as below and will just use the wp_list_pages function's "title_li" attribute to display "select a sub-page" (not exactly what I was looking for but simple enough and I can work with it for the design of the website I need it for).
<h1><?php echo get_the_title($post->post_parent);?></h1>
<h2><?php if (is_page() && $post->post_parent > 0 ) { the_title();}?></h2>

Can I use images as anchor tags with <?php previous_post(); ?><?php next_post(); ?>
Rather than displaying the title of the next page, I would like to display a large arrow that can be clicked on. To do this I shall either be using image files, or the __tag.
Can this be done? | Well, yes, of course. Take a look at this reference:
< <
You can customize it however you like, so you can simply put an html image tag in there. The function must be used in the loop to work. I'd do it like this:
<?php previous_post_link('%link', '<img src="Image URL" width="20" height="20" alt="%title" />'); ?>
The first parameter controls what comes before and after the link. Because we don't want anything before or after the link, but within, it's just the link.
The second parameter is crucial. It says what text should be linked. Here, instead of text we put in the image we want. I've also added the post title as alt attribute.

Personal page for every user (not just authors)

I'm a bit clueless about how to achieve that. Any suggestions? | I guess what you're looking for is an author template. You can create an author.php in your template folder and arrange the information in there like you want to. It will be a general template for every user then. You can access the author page if you visit example.com/author/author-slug/
To give an example: <
I'm sorry it's a german site. However, you see that on this author page all posts from this author are displayed. But like I said, you can put whatever information you want into the template, like the description ect. I guess it's the easiest way.

Upgrading themes never works
I have a Wordpress installation running on my own server at home, serving a domain name I bought. It's running on Debian Linux, currently installed under `/usr/share/wordpress`.
When I'm in the Admin panel, I see notifications for updates to the themes or plug-ins. So, I SSH into my server, turn on the FTP daemon, then start the update. Below is an example output:
Downloading install package from
Unpacking the package…
Installing the plugin…
Could not create directory. /var/lib/wordpress/wp-content/plugins/akismet/
Plugin install failed.
This is starting to get a little annoying. The directory exists, and the user that the FTP is running on (www-data) has write access to the folder. Why can the Updater not remove the old plug in, then install the new one?
* * *
Meta Discussion about being on or off topic | `Could not create directory` is still a permissions error; have you checked Changing File Permissions « WordPress Codex? Are wp-content, themes and plugins 755?
> Any file that needs write access from WordPress should be owned or group-owned by the user account used by the WordPress (which may be different than the server account). For example, you may have a user account that lets you FTP files back and forth to your server, but your server itself may run using a separate user, in a separate usergroup, such as dhapache or nobody. If WordPress is running as the FTP account, that account needs to have write access, i.e., be the owner of the files, or belong to a group that has write access. In the latter case, that would mean permissions are set more permissively than default (for example, 775 rather than 755 for folders, and 664 instead of 644). | stackexchange-wordpress | {

Detecting errors generated by $wpdb->get_results()
How do I detect errors when using $wpdb->get_results()?

$result = $wpdb->get_results("SELECT * FROM this is not a valid query");
The preceding code doesn't generate any exceptions or errors; it simply sets $result to an empty array.

So something like this would do the trick.

Change default screen option value for posts per page

The Best Way to always load the newest version of 3rd party code
There is a class for plugins and themes that makes custom meta boxes easier to develop called cmb_Meta_Box from Custom-Metaboxes-and-Fields-for-WordPress at < and they update that class and code.
I'm trying to make sure that if I use the latest version of this class/script in a plugin that if a user has an older version of it, it fails gracefully. So, for example, 1.1.0 has some new features, but if someone already has loaded 0.9.0 from another plugin that loaded before my plugin, what can I do? There is now a constant so I'm thinking I could warn the user on my admin pages, but if they're not technical they wouldn't know what to do with that warning.
I hope this makes sense and some folks have ideas what I can do within WordPress to solve this possible issue.
Thanks! | Short version — there isn't one. WordPress doesn't handle dependencies logic in any form. If library itself doesn't include any mechanism for it (which is exceedingly rare) — there isn't anything you can do.
At best you can (and should) check if expected version of dependency is loaded (if it exposes version in some form or at least by location it's loaded from).
In private sites this can be handled (via Composer for example), but there is no good solution for publicly distributed code. | stackexchange-wordpress | {

WordPress Terminology Options Vs. Settings
What term should be used when defining a page in the admin menu that allows you to change a plugins options? | These two are pretty close, but relate to slightly different stages of the process. In purely technical terms WordPress has two different APIs — Options API and Settings API.
Options API deals with saving and retrieving options from database. So its scope and scope of "options" in terminology is that of purely _storage_.
Settings API deals with admin pages, forms, receiving/validating/sanitizing data, and finally using Options API to store it. So in terminology it refers more or less to level of admin interface and user interaction.
Depending on nature of your plugin its page should be named either after its own name or after what plugin does. Then it should be nested appropriately in a level such as Settings or Appearance. Creating top level pages for the plugins is not uncommon, but is often considered overblown and annoying, especially so if the plugin/theme doesn't have _many_ things to put there. | stackexchange-wordpress | {

How to style the post previews/links without it affecting the main posts?
I am a beginner but have spent a lot of time in trying to figure this out and to no avail.
Using the developer tool in Chrome I have tried to find a particular class that's unique to the posts that show as previews in the homepage of a new WP site I am creating. But all of them are also applied to the _main post_ that arrives when you click the link to the post.
So, what's the solution?
I want to make the home page links look most like _featured posts_ that many sites have with a rectangular shape, with the posts main image as background or something. | As long as your theme is set up in the "normal" way, this is fairly easy.
Lets take the markup for the Twenty Fourteen as an example. The type of page you are currently viewing creates a class on the `<body>`. So for a front-page blog (several articles) the `<body>` element contains the class "blog", A single post contains the class "single". (There are also classes like "archive" and "page" and so on.)
So to format a single post, you add ".single" to your css.
/* css */
.single .post {
/* affects only single posts */
}
.single .post h1 {
/* affects only the <h1> of .single posts */
}
To format the list of posts on a blog page, you add .blog.
/* css */
.blog .post {
/* this affects only posts on a .blog page */
}
.blog .post h1 {
/* this affects only the <h1> of posts on a .blog page */
}
So keep using DevTools, but take a look at the classes of the `<body>` element. | stackexchange-wordpress | {

What data does WordPress theme update pull If there is an update?
I'd like to know what WordPress pulls to notify updates from the code.
I'm currently facing an issue where my theme happens to have the same name as another theme which is already in the repository and it's notifying me that I'm currently using an older version of the theme. What's even worse, my theme gets replaced with that already existing theme when I click update.
So it'll be great if I could just change a code or two to prevent this. I've tried changing the 'Theme Name' in style.css in the root folder (do I have to wait for this to update?) but it's not working.
Note: I'm using my theme in MAMP (connected to the internet, of course).
Does anyone know how to solve this?
Thanks | Very typical and very annoying situation unfortunately.
WordPress doesn't "pull" update information. Instead it _submits_ plugin and theme information to the API at wordpress.org, which responds with updates available. In practice matching of updates is loose and exact logic is not disclosed. Name matters a lot, folder name as well. Rest matters to some unknown degree.
The closest to solution is filtering your theme's data out of HTTP requests to the API via `http_request_args` filter. There is old post on topic excluding your plugin or theme from update checks, but as of recently API requests had been changed to use JSON and code no longer applies as-is. | stackexchange-wordpress | {

add image size still doesn't work even after regenerating thumbnails
I'm encountering this very frustrating problem where `add_image_size()` just doesn't seem to work at all (in fact, I've never seen it even work before). By not working, I mean not resizing / crop (if I take away my CSS width / height, the thumbnail will be the exact size in which I have uploaded it).
I do have:
1. `add_theme_support( 'post-thumbnails' )`
2. `add_image_size( 'small-thumb', 60, 60, true )`
3. `the_post_thumbnail( 'small-thumb' )`
4. And most importantly, yes I've been regenerating my thumbnails close to 50 times now after changing the `add_image_size()` and it's not working.
Now I do have a question related to this problem: Does CSS styling like `max-width`/ `max-height`/ `width` / `height` or anything effect WordPress' thumbnail functions?
Anyone seem to know what else I can try to fix this?
Thanks | There are a couple of things to check here.
First, make sure that `add_theme_support( 'post-thumbnails' )` is loaded before `add_image_size( 'small-thumb', 60, 60, true )`
You can always hook everything through a function to the `after_setup_theme` hook. I always add these in my theme setup function
function wpse_setup_theme() {
add_theme_support( 'post-thumbnails' );
add_image_size( 'small-thumb', 60, 60, true );
}
add_action( 'after_setup_theme', 'wpse_setup_theme' );
Apart from that, everything should work if you call your post thumbnail correctly in the loop.

Where the WordPress Core Translation is "actually" taking place?
I'm a WordPress Core Bengali translator, currently translating and/or fixing existing translations of WordPress 3.8x Bengali in Translate.WordPress.org.
Suddenly, yesterday I got an update notification in all my `WPLANG` '`bn_BD`' sites that, a new version of WordPress Bengali for WordPress 3.9 has come, so update your system. After the update I found a bluff update, because all the previous strings those were translated, got untranslated strings now. So, it's a bogus translation at all.
As a Core translator, I jumped to the translate.wordpress.org's WordPress Projects, but found no such 3.9x translation project there.
I wonder, **from Where** the official language release just happened, (as v3.9 is NOT a Dev. version now, it's a released one) if there's no such project's running!? | I maintain WordPress Bengali project and yesterday I pushed the 3.9 translation update from bn.wordpress.org.
You are right, there are no 3.9.x branch there so it's pretty much not clear to me as well. Here's how it works: we should always translate from the Dev version. When a new release comes, there is a SVN revision for that WordPress release. We just refer to that revision and build a language pack from the development version (trunk). So whatever it's there, its been released as the new version.

Is there a way to fire other functions from wp_insert_post
I am creating a new post using the `wp_insert_post` function. Here's what that code looks like:

'post_excerpt' => $repost[excerpt],
'post_author' => 1,
'post_type' => 'post',
'post_category' => explode(",",$catlist),
);
wp_insert_post($new_post);
The post is created fine, but I'd like to fire some other functions, such as Jetpack's social posting tools (Publicize.) Is there code to do that or would I be better in changing the post_status to draft and setting a future publishing date? | Use this code snippet to use another function,

Automated Footer information

Using Wp_Query without the loop?
I want to query for posts with a certain meta value. I would use the `WP_Query` but when in a loop (correct me if i am wrong.. I am learning wordpress; is it only when in loop? is the `the_post()` that sets the globals?), it changes the `global $post`.
Is it possible to loop without setting up the global values? I just want to fetch some stuff in the posts, i don't want to use `the_content`, `the_title`, etc.. just raw rows of arrays?
If I want to query `WP_Query` with meta fields conditions and expect and want only post, how do I get it? Do I still need to loop? | The query itself doesn't change globals, however you are correct that `the_post()` does.
The most contained way to just retrieve posts (as array of results) is using `get_posts()` function, which is wrapper around `WP_Query` and takes same arguments. | stackexchange-wordpress | {

Get all fields inlcuding "ACF" (Advanced Custom Fields) columns in wp_query
When retrieving posts with wp_query how do I make the loop contain the acf fields?
$args = array( 'post_type' => $postTypes,
'posts_per_page' => $numPosts,
'offset' => $offset,
'meta_query' => $filterArgs );
$loop = new WP_Query( $args );
$postTypes is an array I have filled in advance containing "post", "page" etc. whatever I need.
The loop will contain only the "standard" WP columns like post_content and so on. | The loop doesn't really contain anything.
It does include methods in order to easily output your data such as `the_title()`, this is done when calling `the_post()`
Then, within the loop you'll be able to use get_the_ID() and get_post_meta() to get your custom fields (including ACF ones).
So if you have retrieved your desired posts from that query then you'll be able to do this:
<?php while($loop->have_posts()) : $loop->the_post(); ?>
<h2><?php the_title(); ?></h2>
<?php the_content(); ?>
<p>My Custom Field: <?php echo get_post_meta(get_the_ID(),'my-custom-field', true); ?>

How to find meta entries with their posts missing via SQL?
I'm looking to write an SQL query to do the following:
Select all postmeta rows where the meta_value = a post id that does not exist.
For example, postmeta meta_value may equal 235. Usually this would relate to a post (attachment) with 235 as an ID, however, it has been deleted. I want to find any postmeta rows like this and remove them.
Hope this makes sense! Thanks in advance.

WHERE m.meta_key = 'image'

Twenty Fourteen theme and the page-templates folder
I have to confess I'm struggling to see how the Wordpress Twenty Fourteen theme picks up templates put in the theme's `page-templates` folder. Previously I'd create new templates named `page-<slug>.php` in the theme's root folder, but not now.
I've searched the code for mentions of `page-templates` and not found any where files are included; searched the WP source code too and found none.
Can you explain how they're detected and picked up please? | The actual query for a Theme's page templates happens in `wp_get_theme()->get_page_templates()` (source), which in turn calls `get_files()` (source).
The magic happens here:
$files = (array) $this->get_files( 'php', 1 );
The args for `get_files()` are:
function get_files( $type = null, $depth = 0, $search_parent = false ) {}
So, when WordPress searches the Theme for PHP files, it passes a `$depth` argument of `1`, which means that it searches in subdirectories of the Theme root directory. | stackexchange-wordpress | {

Change the Permalink for wordpress attachment

`/images/post_title` | Your rule works with the attachment ID, so I'm not sure how you're using the title, but the answer is almost identical in either case. The filter you want is `attachment_link`:

return home_url( '/images/' . $post->post_title );
