Wordpress Pods Custom Post Type - separate Media Upload folder for each custom Post Types
I searched but unable to find the answer. I am using Pods Framework for creating custom post types in Wordpress. I want each user roles to have different media upload folder so like I have a post type 'local news' and another post type 'books' and two user roles like 'news editor' and 'book publisher'. So when news editor upload images in local news post type then it should not have access to all my images from uploads directory. and same with book publisher.
So they can not see each others media and it will also be easy to manage images with separate folder for each post type. _How to achieve this ?_ | WPBeginner appears to have an article that addresses what you are talking about.

$wpdb->prepare with LIKE returning blank array instead of rows
I trying to select data from a table using LIKE and wildcards. I tried basically everything. Here'is the last code according to WordPress documentation:
<?php
global $wpdb;
$table_name = $wpdb->prefix . 'city';
$city= 'New York';
$city = $wpdb->esc_like( $city );
$city = '%' . $city . '%';
$prep = $wpdb->prepare("

", $city);
echo $prep . '<br><br>';
$rowsSelected = $wpdb->query($prep);
print_r($wpdb->last_result);

Can I add the post featured image to a specific RSS feed?
I'm currently using the following code:

Trying to create a mouseover effect in html using Gutenberg editor

Creating a return url for getting data from external api

'callback' => array( $this, 'your_callback_function'),

Check if a filter or function has been already been called
Is there a way in WordPress to check, on a screen load, if a filter has been called or a function has run?
I seem to recall some way to do that, but don't recall the specifics.
A filter is being called 3 times during a page load and I want to check if it has already been called before I run various db intensive code again.
My questions is not specific to `the_content`, but for example:
add_filter( 'the_content', 'asdf_the_content', 99, 1 );
function asdf_the_content( $content ) {
// check if the_content has already been
// filtered by some other function
$content = ucwords( $content );
return $content;
} | You can use a static variable to achieve this:
add_filter( 'the_content', 'asdf_the_content', 99, 1 );
function asdf_the_content( $content ) {
static $has_run = false;
if ( $has_run ) {
return $content;
}
$has_run = true;
// check if the_content has already been
// filtered by some other function
$content = ucwords( $content );
return $content;
}
The `$has_run` variable will be `false` on the first run, and subsequent runs it will be `true` and the code will not continue. Static variables like this inside a function maintain their values during each execution, instead of initializing like normal variables.
Another example:
function add_one() {
static $total = 0;
$total++;
echo $total;
}
add_one(); // 1
add_one(); // 2
add_one(); // 3 | stackexchange-wordpress | {

How can I fetch user registration age

PHP file won't work in wordpress folder, but works in another virtual host
So basically I made a php file that is called with two arguments (order total and order number) and it spits out a png with an EPC QR Code (so people just scan it and their banking app fills in all the details).
This file works in an empty virtual host, but it won't work when I put it anywhere in a wordpress directory/virtual host.
Is there some setting somewhere that is keeping non-wordpress php files from executing? | Yes. The default WordPress .htaccess file. Without edits, all calls are redirected to `index.php`.
Your best bet is to pass the call through WordPress as a custom plugin. This answer deals with setting up a REST endpoint. Of course, that means returning JSON which might not be exactly what you are looking for.
Another approach might be to edit the `.htaccess` file.
Something like this, near the top:
RewriteRule my-qr-code.php$ - [L]
This tells the server that in this case, if the file matches, we are done. That solution comes from a StackOverflow question. | stackexchange-wordpress | {

WP-CLI update date and time format
I'm new to WP-CLI. After a lot of Googling and searching in this forum, I haven't found out which is the command to update both date and time formats.
wp option update......
Thanks for any help!
Regards | The wp-cli command structure would be:
wp option update timezone_string "American/New_York"
So:
1. _option_ to act on a WordPress option
2. _update_ to update the option
3. the _option name_ , in this case 'timezone_string'
4. the new _value_ , in this case 'American/New_York'
Items 3 and 4 are defined by WordPress, a plugin, or other custom code.
Number 4, the value may have only a limited number of valid values. In this case, something other than a standard timezone would cause problems.
Generally speaking, I update the timezone, time format and start of week to Sunday.
wp option update timezone_string "America/New_York"
wp option update time_format "g:i A"
wp option update start_of_week 0
So research your basic WordPress options to determine the option name and the valid values, then structure your command line appropriately. | stackexchange-wordpress | {

`save_post` hook called on inserting new post from front end

How to deal with Slow HTTP POST (slowloris) vulnerability
I'm using WordPress Version 5.2.2
I've been asked to implement changes highlighted as required by a security scan, the problem is I have little access (none in fact I think) to the webserver configuration, which makes some changes, difficult.
Is it possible for me to deal with Slow HTTP POST vulnerabilities in WordPress, (< without changing the server configuration? | No, there is nothing you can do if you are unable to modify the HTTP server behavior. The reason is that the HTTP server receives and processes the initial request and then hands it off to PHP. PHP then processes the request and hands the response back to the HTTP server, which then sends it back to the client.
PHP does have a built-in HTTP server but it is HIGHLY unlikely that Kinsta is using it and it does not appear to offer any kind of configuration and moreover, is not recommended for production or even public use. See < for details. | stackexchange-wordpress | {

Most scan for Tim Thumb throughout your whole file structure, including themes (and will also search for many other types of vulnerabilities if you've been hacked, as your "hacked" tag indicates).
You can also search for files named "timthumb" in your theme directory, or search for the phrase "timthumb" in all files on your site. It helps if you have a local copy and a good editor that will search through files. | stackexchange-wordpress | {

403 forbidden access to my whole site
Yesterday I tried to add some lines of code to my `functions.php` and suddenly the whole site throw 403 forbidden error. Both frontend/admin. Asked my hosting provider ( SiteGround ) and they said it is blocked because of security reasons as far as I understood. How can I check for malwares if I can't access my admin panel to install plugin for this. Also downloaded the files on my local server ( I am using LAMP stack on Ubuntu 18 ) and when I try to reach my local domain it redirects me to the site again with 403 forbidden error. What I tried to add as code is :
function test() {
echo "TEST";
}
add_action("test", "test")
After that I have deleted it through FTP. Hope I explained the situtation clearly. If you need more info to give me some advice will provide it immediately. Thank you! | You need to look at all files via your hosting File Manager (or FTP). Look for any code that shouldn't be there.

Select multiple categories with is_tax
i have a good function for exclude out of stock products from category. The problem is i want exclude for more than one category (really i want show only in one category, but i think this is the way. If someones know how show only in one category...). Here is the code. thanks!

how to pass args for archive.php query?
I am trying to pass args to archive.php so that I can order the posts, set the number of posts, etc..
but the query is done like this
<?php if (have_posts()): ?>
<?php while (have_posts()): the_post();?>
if it was`new \WP_Query($args);` i was able to pass the args here but this can't be done in archive.php template? | The `pre_get_posts` hook can be used to modify queries before they're run. You can use `$query->set()` to set arguments on the `WP_Query` object, and `$query->is_main_query()` in the callback to limit your changes to the main query:
add_action(
'pre_get_posts',
function( $query ) {
if ( ! is_admin() && $query->is_main_query() ) {
$query->set( 'posts_per_page', 12 );
}
}
);
You can't target specific _templates_ , but if you want the change to only affect archives, you can use `$query->is_archive()`, which will be true for date, taxonomy and post type archives, or if you only want to apply the changes to the category archives, you can use `$query->is_category()`. Many of the normal conditional functions are available as methods for checking the current query. | stackexchange-wordpress | {

How do you output an unknown number of images in a custom post type with desired markup?
I'm working on a theme that will have an image gallery within a custom post type.
I'm able to insert them into the post (using Advanced Custom Fields and embedding them in a WYSIWYG box) but I was wondering if there was a cleaner way to do it, such as using the image uploader field of ACF and an option to (e.g.) ADD ANOTHER.
Then I would like the images to appear wrapped in DIVs and with some specific markup to get them to play nicely with the Owl Carousel code I've set up.
I don't know how many images each entry will have.

How can I access core/paragraph textColor in a block template
I am trying to set the default textColor of an Innerblocks => paragraph in my Gutenberg block plugin.
The problem seems to be that placeholder is an attribute but textColor is passed as a prop <
Wondering if anyone has figured out how to set this. Or if it is not possible.
The documentation does not seem to cover this <
<InnerBlocks
template={[
["core/paragraph", { placeholder: "Enter side content...", textColor: '#EF4A23' }]
]}
/> | **As of the end 2020** , I have found that the best way to find attributes related to a core block is to inspect it with the react developer tools.
Under the components tab, search for `[BLOCK_NAME]Edit` to find the editing component, where `[BLOCK_NAME]` is something like "Paragraph", "Heading" or "Button".
Then on the right side in the inspector you can see the related attributes.
**To answer the original question** , at the current moment, the attribute is `textColor`.
const TEMPLATE = [
[
'core/paragraph',
{
textColor: '[YOUR-COLOR-SLUG]',
},
]
]
In my case entering an hexadecimal value doesn't seem to work. But this might be because I have disabled the custom color selector globally. | stackexchange-wordpress | {

Wordpress API standard compliance and specification for external database
HOW TO CONNECT WORDPRESS WITH EXTERNAL DB SERVER VIA API? | WordPress has the HTTP API that you could perhaps use to send POST (`wp_remote_post`) or GET (`wp_remote_get`) requests to an API, < But you could also use cURL to send the requests, I think.
If the API is developed by you, then it's up to you to decide what kind of arguments the API accepts/expects and what kind of authentication it requires. If it's some 3rd party API, then you need to consult the API documentation to see what is needed to get a response from it and in which form you'll get the response - e.g. is it a JSON response.
Or if you can skip the API and connect directly to the database, then you could perhaps use `$wpdb` to do it as described here, Using wpdb to connect to a separate database | stackexchange-wordpress | {

Can I use wp_oembed_get to detect a valid embeddable link or is there a better way to do so?
I am looking for an efficient way to detect if user input is a valid embed link (and of what type). I know that one can cause WordPress to run its embed code with arbitrary input.
For example, like this:
$embed_code = wp_oembed_get($some_string);
if($embed_code!=FALSE){
// do something clever
}
Assuming that there is at least some link, it will return a fully marked up link failing all else. The behaviour I am after, however, is to be able to feed it some user input (after appropriate sanitation) and get back either a fully marked-up embed or a FALSE but not a hyperlink if the content is a URL that it does not recognise. The purpose is to detect if the given input text is a valid embeddable URL.
Can (or should) I use `wp_oembed_get` to detect a valid embeddable link or is there a better way to do so? | The regex patterns for matching embeddable URLs are stored in `WP_oEmbed`, which has the method `get_provider()` for checking if a given URL is an embeddable URL for a supported provider.

How do I use jQuery to add the TinyMCE WYSIWYG editor to a textarea?
Using jQuery (as part of a theme or plugin) how can I add the WYSIWYG (TinyMCE) rich text editor to a `<textarea>`? Specifically, I want to activate it upon certain conditions being met (changes in the form etc.).
I have a timer event that checks the text size periodically for a number of reasons, this will be the function that activates the editor.
What do I need to do to make the TinyMCE available on a front end and attach/activate it as required? (looks like the user is writing a lot of text, activate TinyMCE). I assume there is something I need to enqueue but, beyond that, I'm just guessing.
My question is related to this one but differs in that I want to do this with jQuery. Also related, this one, but that's only a partial answer (I still need to know what to hook). I need to set it up and then activate with jQuery. | I would just use the WordPress JavaScript API for TinyMCE -- `wp.editor`.
The steps in brief:
1. PHP: Enqueue the editor scripts (and styles) via `wp_enqueue_editor()`.
2. JS: Call `wp.editor.initialize()` from your script.
And do take note of this: (the "this function" refers to `wp.editor.initialize`)
> If this function does nothing, please make sure that `wp.editor.getDefaultSettings` is a function.
Which means, if it's not a function, then while there are no errors thrown in the browser/console, the `textarea` will not be converted to a TinyMCE editor. | stackexchange-wordpress | {

Headless Wordpress + Vue.js on the same server
I have found many articles about headless wordpress and vue.js using data via WP REST API. In these articles they deploy the app on separate servers. Backend is on different server than frontend. I'm trying to find out how to deploy the app on one server.
Until now I come up with one solution: On the server create subfolder ( subdomain ) for CMS and on public upload the Vue frontend and pull the data from subdomain via WP REST API endpoint.
Is it possible to connect Wordpress and Vue without creating subdomain? I would like to upload the vue app right in the folder where is Wordpress. I think I can't put it in the theme folder of the wordpress and keep it separate at the same time. Any solutions? | Yes, it is possible to connect WordPress and Vue without a subdomain. As you're pulling data via the WP REST API it doesn't matter where WP is - same or different server, subdomain or subfolder - as long as you know its url.
You could have your Vue related files (e.g. index.html, app.css, and app.js) for example in /public_html and WP installed in /public_html/wp folder. You could then access WP from youdomain.com/wp and your app would be in yourdomain.com.
Mixing WP files and your Vue app files probably isn't a good idea as WP needs its index.php to function properly. But you could create a theme with just a index.php file in it, which would load your app scripts and the app root (i.e. `<div id="app"></div>`) element. | stackexchange-wordpress | {

What's the difference between home_url() and get_home_url() from a developmental point of view?
Both functions return the website url.
And, as home_url() needs sanitization (for example `<?php echo esc_url( home_url( '/' ) ); ?>)`, why it is this snippet of code, instead of `<?php echo get_ home_url( '/' ); ?>`, that we found in Wordpress Codex and Wordpress Template Twenty Nineteen ? | There isn't much difference but they are **not** the same.
### get_home_url
`get_home_url()` takes null or a blog id as the first parameter. As per documentation here.
> get_home_url( int $blog_id = null, string $path = '', string|null $scheme = null )
If you are dealing with multiple homes (as in, say a multi-site set up) this might be useful.
## home_url
`home_url()`, on the other hand, is less fussed about per blog settings and just wants the home URL. As per documentation here.
> home_url( string $path = '', string|null $scheme = null )
It is the equivalent of calling `get_home_url( null, $path, $scheme );`. Most of the time, this is the function you want. | stackexchange-wordpress | {

When I've built static sites in the past I've had an includes folder and used php if I've needed to repeat components / HTML over different pages.
I've noticed in Wordpress that this functionality is undertaken with a `template-parts` folder which seems to do the same thing.
I'm about to start building a custom theme for the 1st time and my question is, is there a reason why I should use `template-parts` instead of an `includes` folder, and if I use an `includes` folder will there be any negatives to this?
Many thanks | It doesn't matter. It just has to do with standard naming in WordPress because you typically call your "parts" with `get_template_part();`.
`get_template_part();` checks if the file is in the child theme first, then uses the one from the parent theme if it doesn't. It provides a way for you to override template files from the child theme. | stackexchange-wordpress | {

Is there a way to test if a URL is part of the current blog?
In a scenario where, say, your plugin or theme has been given a URL. You want to know, is this URL a URL from this very blog? How would you test if it is? | One option could be to use `url_to_postid( $url )`, which returns a " _ID of the post or page that resides at the given URL, or 0 on failure._ ", <
But this doesn't work with archives, I think. To find out if the url is for an archive, you'd probably need to `explode()` the path and then do some kind of `get_term_by()` with the parts.
Perhaps a little less strict way would be to compare the url's host to your domain,
if ( false !== strpos( get_home_url(), parse_url( $some_url, PHP_URL_HOST ) ) ) {
// do something
}
or
if ( parse_url( $some_url, PHP_URL_HOST ) === parse_url( get_home_url(), PHP_URL_HOST ) ) {
// do something
}
But doing it this way, you wouldn't know, if the path was correct or not. | stackexchange-wordpress | {

Hide price and add to cart button on product page only
I’m using Datafeedr to show price comparison sets on a product page. The price comparison table opens up dynamically once the page is loaded. But because I want people to follow the link to the cheapest store that offers that product I really have no use for each imported product to show it’s own price. That price could be higher than the prices that are shown in the comparison table and the link of the button would then send the visitor to the wrong store. I have a plugin that turns of the prices and add to cart buttons, but it also turns of the prices on the category pages. And I do want the prices to show there because on the category pages people can filter the prices or set a price range. Can someone tell me with which snippets I can leave the prices in the category pages, but hide them on the single product pages and also how to hide the add to cart button?

Query posts with "non set" meta value
I'd like to make a query of custom posts based on a custom field, say `instrument`.

Connect to database in the header of my WordPress website
I have created a table in my WordPress database. Now, WordPress gets all its data about different posts and pages from the database. This means that WordPress always connects to database automatically without theme developers writing any code.
I want to get information from a table I added to the database inside the `header.php` file of my theme. My question is do I need to create a WordPress database connection by loading all the files like
require_once(__DIR__."/../wp-load.php");
require_once(__DIR__."/../wp-config.php");
$connection = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
Or I can use the existing database connection. If I can use the existing database connection, how do I do that?
Thanks. | You can (and should) use the existing database connection by accessing `global $wpdb`. The simplest way to use it is with the `get_results()` method:
global $wpdb;
$results = $wpdb->get_results( 'SELECT * FROM my_table' );

Adding product SKU before cart item name in WooCommerce

}
}
add_filter('parse_query', '_s_staff_query'); | Your functions are already simple enough, and secondly, the functions do different things:
* `_s_staff_query()` filters the posts query variables and the function has to run _before_ `WP_Query` queries the database.

Although the path for directory is correct it returns false. Can Anyone explain why this happen? I am new to PHP and Wordpress. Thanks. | `file_exists()` lets you check if a file exists on the local server, by passing it a file _path_. It cannot be used to check for the existence of files via _URL_ , and you're passing it the result of `get_stylesheet_directory_uri()`, which returns the URL (http:// etc.) to the file, not the path.
The proper way, these days, to get the _path_ to a theme file is to use `get_theme_file_path()`, like so:
$filecs = get_theme_file_path( 'css/lucilevi.css' );
$filejs = get_theme_file_path( 'js/lucilevi.js' );
if ( file_exists( $filecs ) ) {
// etc.
}
if ( file_exists( $filejs ) ) {
// etc.
}
Just be aware that because `$filecs` and `$filejs` are file paths, you cannot pass them to `wp_enqueue_style()`, `wp_enqueue_script()`, you still need to pass URLs to those. | stackexchange-wordpress | {

Htaccess redirect after changing Language URL format
After have changed the URL language format from
to
I'd like to redirect the former URL versions to the actual ones.
I found this code snippet online and apparently it partially solves my problem.
<IfModule mod_rewrite.c>
RewriteEngine on
RewriteCond %{QUERY_STRING} lang=en
# exclude all requests starting with /wp-admin/
RewriteCond %{REQUEST_URI} !^/wp-admin/.*$
RewriteRule ^(.*) /en/$1? [L,R=301]
</IfModule>
However, it is designed for `lang=en` only!
How could I also include `lang=ru` in it so that it will redirect both `lang=en` and `lang=ru`?
Thank you in advance for any valuable hint! | In order to catch either `lang=en` or `lang=ru` you can change those directives like this:
RewriteCond %{QUERY_STRING} lang=(en|ru)
# exclude all requests starting with /wp-admin/
RewriteCond %{REQUEST_URI} !^/wp-admin/
RewriteRule (.*) /%1/$1? [L,R=302]
The `(en|ru)` part matches either `en` or `ru` and the surrounding parentheses make this a _capturing group_ that can be referenced later.
The `%1` (note the `%`, not `$`) in the `RewriteRule` _substitution_ is a backreference to the captured group mentioned above. So, `%1` holds either `en` or `ru`.
The trailing `.*$` on the end of `!^/wp-admin/.*$` is superfluous. As is the `^` prefix on the `RewriteRule` _pattern_ `(.*)` \- since regex is greedy by default.
Test first with a 302 (temporary) redirect and only change to 301 (permanent) when you are sure this is working OK - to avoid caching issues. | stackexchange-wordpress | {

Create and Update 2 CPT sequentially
Is it possible to create + update a CPT after a post have been created sequentially in the same flow?

Second: wp_update_post($my_second_cpt) (with DATA from $my_first_cpt, for example a random seed) and show be executed inmediately after

Headless WordPress – Issue with plugin path

to:

`www.example.com/%category%/%postname%/`

`www.example.com/category1/my-post/`
`www.example.com/category2/my-post/`
They will go to the same post but the URL does not change, isn't this classed as duplicate content? Will Google and other search engines penalise a site that uses this practice? What is the recommend approach to this problem? | It should not affect it because Wordpress redirects links to post leaving you with only one canonical and working one.

Hook to change HTTP response headers
I want to write a simple Wordpress plugin. The plugin will:
1. Read (if set) a cookie from the visitor
2. Send a cookie (if not set) to the visitor
3. Depending on the cookie value I will redirect the user to a new pages
I found some documentation for getting/setting cookies through WP, and I'm guessing I can just issue a redirect from PHP. So I downloaded the WordPress Boilerplate (WPBP) code and so far so good. But I'm stuck at:
1. Which WP callback should I hook into for my code? (init ?) I found the plugin documentation but I'm struggling to understand where this type of code should hook into.
2. Should I put any of my code into the main/global portion of the WPBP file? Or only in the called back function.
3. This plugin will run on a WP multisite installation. Does that mean my plugin code would run on every site? If so, how could I restrict my plugin code to run on only a particular site? (PHP check for a URI?) | Your questions about how you should structure your plugin are somewhat too broad, but here is a specific answer to the title question.
To change headers before they’re sent, use the `wp_headers` filter.
function tsg_filter_headers( $headers )
{

// print_r( $headers );
// It’s a good idea to leave the admin alone
if ( !is_admin() ) {
// Add or redefine 'Content-Location' header
$headers['Content-Location'] = '/my-receipts/42';
}
return $headers;
}

How to remove "Category : ..."

I found this similar post : Remove "Category Archives: title" at the top of a category page

I would greatly appreciate your help, thank you :) | That title is coming from `archive.php` file of TwentySixteen theme.

<header class="page-header">
<?php
the_archive_title( '<h1 class="page-title">', '</h1>' );
the_archive_description( '<div class="taxonomy-description">', '</div>' );
?>
</header><!-- .page-header -->
In case you want to show only Category name as page title, then instead of removing the above code from `category.php` file, just replace the `the_archive_title` method with:

Yoast SEO settings unavailable in an archive page from wordpress plugin
My Wordpress site has "Seriously Simple Podcasting" plugin installed to serve the podcast feature.
This plugin comes with a podcast archive page(click to open) on my site. The page shows correctly for users, but lacking 2 important SEO functions:
1. Yoast plugin is unavailable/invisible, i.e. I cannot set `search keyword`, `meta description` etc for this archive page.
2. I cannot change the H1 title from `Podcast Archive` to whatever I'd like to have
What can I do to achieve the 2 SEO goals above, **whether configuring, installing extra plugins or extending php code**? | 1. Yoast SEO can have limitations for archive pages.

2. That title is inserted through your theme. You can open the file archive.php and look for the insertion of headings.

Multiple Custom Taxonomy Rewrite
I have registered two custom taxonomies of 'location' and 'type' registered before my post type of 'chalet' and have the rewrite rules set to

.../chalets/
.../chalets/[location term] eg /chalets/val-thorens
.../chalets/[type term] eg /chalets/ski-chalet
This works to a point but the second rule (whichever taxonomy is registered second) overrides the first and so the first subsequently returns a 404. How can I have both rewrites work or am I asking for the moon on a stick? | You must use separate base for both custom taxonomies. For example:
default URL: /chalets/
location term URL: /chalets/location/%location%

How to use do_shortcode_tag to modify the output of a shortcode?

function test_sc( $atts ){ return "$\frac{15}{5} = 3$"; }
By writing `$\frac{15}{5} = 3$` in a page this gets displayed  tags, it runs shortcodes and even sends the content to the theme and any plugins so they can do their thing to the content and include their bits.

When does global/main code of plug execute?
I am creating my first wordpress plug, and am using the WPBP template which is a great timesaver.
In the main of the plugin (called myplugin.php), I added a simple command to write a line of text to a file. That works, however, when I refresh the page (one page of my website), I see approx 4 lines written to my file.
Does the myplugin.php get included / execute many times for each page? If so, why?
Next, what is the best way to enforce only running once per page. I plan to create a PHP object and don't want to create it 4 time. Obviously I could build my own detection if the class exists, but that seems wrong. Surely WP has devised some mechanism to ensure plugin global/main code only runs once. | Plugins are only loaded once per request. Plugins are loaded with this code:
// Load active plugins.
foreach ( wp_get_active_and_valid_plugins() as $plugin ) {

* Fires once a single activated plugin has loaded.
*
* @since 5.1.0
*
* @param string $plugin Full path to the plugin's main file.
*/
do_action( 'plugin_loaded', $plugin );
}
This is inside `wp-settings.php`, which only loads once, but also note that `include_once` is used, meaning that the plugin couldn't be loaded twice even if that code ran twice for some reason.
However, not that I said _per request_. This means that any AJAX requests that are sent from the page will cause the plugin to be loaded for each of those AJAX requests, in the background. This could explain why the function is running multiple times | stackexchange-wordpress | {

Possible for Category Base and Custom post Type to share the same slug/permalink?

How can I achieve this?
> My workaround is a category URL like this (working using Category Base = `books/category`):

Would prefer to add code in `functions.php` or `.htaccess` than use a plugin.
Thanks | No, it's not safe to use the `/books/` URL for both a category base and custom post type base. WordPress uses the URLs to determine what type of content to serve. If you've set up 2 different types of content at the same URL, it won't have any way to know which you're requesting, and if you end up with a book slug that's the same as a category slug, you'll really have conflicts.
To keep the URL types segregated but still logical, you could use URLS such as
CPT: `example.com/book/title-of-a-single-book`
Category: `example.com/books/category-name`
Or, perhaps something like
CPT: `example.com/books/title-of-a-single-book`
Category: `example.com/book-categories/category-name`
Or, continue using your workaround, `example.com/books/category/category-name`, and they will all appear to be under "books." | stackexchange-wordpress | {

Other data is stored in other fashions, but I'm trying to piece a few together. | If you need to do this conversion in PHP, as part of whatever import process, then you can just convert the comma-separated values into an array with `explode()`, and then use `update_post_meta()`, which will automatically serialise the value for you:

$array = explode( ',', $value );
