What argument does my function need to echo get_results() query results
This is my database query:
global $wpdb;
$table_name = $wpdb->prefix . 'qs_css';
$db_css = $wpdb->get_results(
"
SELECT qs_the_css
FROM $table_name
WHERE qs_css_id = 1
"
);
echo $db_css[0]->qs_the_css; // works just fine
However, I need the query results inside my function:
add_action( 'wp_head', 'quick_qs_db_css', 100 );
function quick_qs_db_css( ) { ?>
<style type="text/css" id="db-css">
<?php echo $db_css[0]->qs_the_css; //outputs null ?>
</style>
<?php }
What arguments does the `quick_qs_db_css()` function need ? Is it possible to pass query results to a function?
Any input would be very much appreciated ! Thanking in advance :) | Why don't you just do..
add_action( 'wp_head', 'quick_qs_db_css', 100 );
function quick_qs_db_css() { ?>
global $wpdb;

$db_css = $wpdb->get_results(
"
SELECT qs_the_css
FROM $table_name
WHERE qs_css_id = 1
"
);

<?php echo $db_css[0]->qs_the_css; //outputs null ?>

WordPress rewrite does not work for some reason
I am learning how to use WordPress rewrites. As a start i am just trying to redirect any request for " **validate_data.php** " to " **validate-data** ". Here is what i have added to the functions.php file:
function custom_rewrite_basic() {
add_rewrite_rule( 'validate_data.php', 'validate-data', 'top' );
}
add_action( 'init', 'custom_rewrite_basic' );
I know i can execute this in the .htaccess file, but i am testing it here as i have a more advanced case, so it is just a start. What happens when i access "validate_data.php" is that it causes 404 error. I hope someone can tell me what i am doing wrong here? | I am new to WordPress rewrites, so after some StackExchange reading i have figured it out. All rewrites should be passed to index.php, then i can call the page that i want to redirect to, like this:
function custom_rewrite_basic() {
add_rewrite_rule( 'validate_data.php', 'index.php?pagename=validate-data', 'top' );
}
add_action( 'init', 'custom_rewrite_basic' );
In addition i wanted to pass some POST data from the old page to the new page, so i did it like this:
function custom_rewrite_basic() {
add_rewrite_rule( '^validate_data.php(.+)/?$', 'index.php?pagename=validate-data', 'top' );

Unable to get Post Category Name and URL
I am very new to wordpress development, please help me out in getting post's category name and its url.
I have tried get_the_category() function but it didn't helped me. Following it the code snippet:
<div class="post-meta-categories"><i class="fa fa-tags"></i> <?php get_the_category(); >
</div> | To understand why `get_the_category();` didn't work we have to take a closer look at the Codex page for that function. More specifically, what that function returns.
> (array) Array of WP_Term objects, one for each category assigned to the post.
You tried to print an Array to HTML, which is why it didn't work.
Instead, take a look at the `get_the_category_list()` function as seen on the Codex, which says:
> Retrieve category list in either HTML list or custom format.
You also forgot to end your php snippet with a `?>`. So to wrap it all up...
<div class="post-meta-categories"><i class="fa fa-tags"></i> <?php echo get_the_category_list(','); ?></div>

TinyMCE removes iframe attributes width and height

Can I include a custom PHP function in a Wordpress function?

<?php $translated_text = esc_attr_x( $text, $context, $domain ) ?>
The `$domain` is optional. That´s the reason it´s a warning. Do you have debug set to true? If you want to fix it you have to add the text-domain.
esc_attr_x( 'Search for:', 'label', 'TEXT-DOMAIN-FROM-THEME' )

Add stylesheet per layout
Could anyone tell me what is the best and most efficient way to add separate style sheet only to one template?

if ( is_page_template( 'template-name.php' ) :

get_template_directory_uri() . '/page-specific-style.css'
);
endif;
}
add_action( 'wp_enqueue_scripts', 'themename_include_page_specific_css' );
Keep in mind, that the parameter you pass to `is_page_template()` must be the name of the template including the path relative to the directory of the theme. Meaning that if your template is in `templates` folder you should write it like:
`is_page_template( 'templates/template-name.php' )`

How can you disable search for non-members on your WordPress website.
I'm making a community social media website using BuddyBoss's Boss theme. I'm also using Buddypress.
Since I want my website to be private, what I want to do is to disable the search function for anyone who isn't logged in to the website.
The titlebar or header of that theme is fixed meaning that search isn't just a widget but an actual part of the titlebar.
Also, can you tell me the best plugin to restrict access to the website to only the logged-in members so that others can't see anything but one single sign-in or register page.
I'm guessing it can also be done by is_logged_in function but I'm unfamiliar with php coding and would very much appreciate it if you help me out.
If it cannot be done without editing files then, here is a link to a few php files like header.php, search.php, etc.
< | You can restrict any area with `is_user_logged_in()` function. For example: If you want to hide search for non-logged-in users then enclose search `DIV` inside this function like this
if(is_user_logged_in()) {
<div class="search">
</div>
}
Search for the `DIV` that contains `Search Box` and apply function as shown above. By this way you can restrict any area for non-logged-in users.
**NOTE** : Since you are new in `PHP`, Don't forget to enclose this function inside php tags (`<?php` `?>`). And also make sure you don't open `<?php` for this function if it already being opened.

Moving a site from a temporary domain to the live domain
So I have been working with Wordpress for almost a year now, almost all of the times i get stuck with the same problem.
When you purchase a hosting you need to give it the domain of the website, now if the domain dont have A record to your host you won't be able to view your website, so you must edit your local hosts file to view it with this domain.
The other option is to work with a sub-domain, which here starts my problem. when you are working with Wordpress it's creating the pages with the Url on the database and than when you finish the website and want to connect to the main domain you need to edit the whole database. (Lets say the wanted domain is xxx.net, and the temp/subdomain is yyy.net)
What are the best ways of moving and connecting the website to the domain after using a sub/temp domain? | So basically you want to change the URL from subdomain to main domain in your DB so that it will work with your main Domain.
What I do is I use search & replace DB script and in this I will enter my subdomain to search and to main domain to replace.

I am running a woocommerce site on wordpress. I have updated to the latest versions.
I am seeing that on some pages in the shop that there is an error printing on the page:
Trying to upload files larger than 256M is not allowed!
My question is not how to fix it, but what file is generating that error message, and how to stop it printing. The page is loading as a shop page, and nothing is being uploaded, so I do not need to see the error! | It was a plugin the was trying to upload on Woocommerce pages, that was failing.

Migrating a live WordPress website to a Local Server: why some elements of the website are missing?
After many many hours (days, actually) trying to migrate a live WordPress website to a local server, I'm finally getting things to work. One really annoying thing was that some elements of the website were missing, and after many more hours I found out that the culprit was some missing `php` in the `<?php` tag. If I add the `php`, the missing element misteriously reappears on the page. The files I edited was php files inside the `/themes` folder.
Is this normal or am I missing something? How to properly resolve this issue? | It turns out that the what I thought to be incomplete tags was actually just the short form of the delimiter (as you can notice, I'm not very familiar with PHP and WordPress).
Instead of editing every single file and appending `php` to every `<?` tag, the solution could not be easier:
Apache > PHP > PHP Settings > short open tag
**Boom**.

Adding an IF ELSE to a function

Extending custom shortcode to also be called directly from theme PHP pages

Run str_replace on title and save the output to a custom field
I need to a make a custom RSS template for my website and I'm having problems getting `substr(the_title_rss(), 0, strpos(the_title_rss(), ' —'));` to work on the RSS feed.
What the above code is suppose to do is if a title has `-` in the title, it removes everything after the `-`.
I think the best way to solve my problem is to run `substr` and `strpos` and save the title in a custom field. I'm not a programmer so has anyone been able to accomplish this or point me in the right direction?
Thanks, | `the_title_rss()` outputs its value straight away so it can't be used in a function like that, you would have to use `get_the_title_rss()`
Or alternatively the_title_rss() has a filter we can hook in to and return your shortened title is possible. (You would add this to your functions.php)
function gg_short_title_rss($title)
{
// This can return false, so check there is something
$short_title = substr($title, 0, strpos($title, ' –'));
if ($short_title) {
return $short_title;
}
// Else just return the normal title

wp_schedule_event run in background or not?
According to codex,
> Schedules a hook which will be executed by the WordPress actions core on a specific interval, specified by you. The action will trigger when someone visits your WordPress site, if the scheduled time has passed.
Assume that I run a function using `wp_schedule_event`. Function need 20-30 seconds to finish their task.
So it will affect to the user or not? I mean if it is run in background like normal cron jobs it is not affect to the user. | It depends. The initial page load trigger should not but performance may degrade as visitors browse your site until the Cron job is finished.
Is the scheduled event you plan on using PHP or DB intensive? How often will it run?
**Here's how it works**
* The scheduled event (aka Cron job) will be initialized once it's due (or past due) by whoever hits your website. So visiting `www.test.com/somepage/` will tell Mr. WP-Cron, "Hey dude, it's time to wake up and run this Cron job".
* If it takes 20-30 seconds to finish and is an intensive DB or PHP task (e.g. lots of DB INSERT or UPDATE statements, or parsing a huge `.xml` file, etc), there's a good chance the site will be slow for _anyone_ during that time. Especially if you're on shared hosting due to shared CPU and memory.
If it's a Cron job you run once a day or week, I wouldn't worry about the performance hit.

Proper way of establishing custom landing pages in WordPress

Where do we edit these two template files? I would like to create my own template file for my "Page" as well. | reference WordPress Codex on Templates
> A quick, safe method for creating a new page template is to make a copy of page.php and give the new file a distinct filename. That way, you start off with the HTML structure of your other pages and you can edit the new file as needed.

Adding JS to one page
What is the best way to add JS script in wordpress and apply it to one page? As I understand, adding it in template is not recommended. My simple JS is:
var allStates = $("svg.us > *");
allStates.on("click", function() {
allStates.removeClass("on");
$(this).addClass("on");
}); | Create a new dir and file dedicated to your javascript. `/js/scripts.js`.
Wrap your entire javascript like this:
( function( $ ) {
var allStates = $("svg.us > *");
allStates.on("click", function() {
allStates.removeClass("on");
$(this).addClass("on");
});
} )( jQuery );
Then in your theme's functions file, put this code. It loads your new js file.
function your_scripts() {
wp_enqueue_script( 'your-script-handle', get_template_directory_uri() . '/js/scripts.js', array( 'jquery' ), '1.0', false );
}
add_action( 'wp_enqueue_scripts', 'your_scripts' );
That way, all your javascript is available on any page and is loaded only once (afterwards, it's in browser cache). Since your function is `on click` it's fine for it to be available on all pages. | stackexchange-wordpress | {

Get ACF value in external jQuery document
I'm trying to get the value of an Advanced Custom Fields _select list_ in an external jQuery document, in order to apply some conditions to it.
I looked for an answer and found only solution involving the use of tags inside the page, which I want to avoid. | Your question is not entirely clear, but it looks like you are in need of `wp_localize_script`, which allows you to pass variables from PHP to a script. You would use it like this (example with two fields):
add_action ('wp_enqueue_scripts','wpse244551_add_field');
function wpse244551_add_field () {
$my_field = array ();
$my_field[] = array (field1 => get_field ('field1'));
$my_field[] = array (field2 => get_field ('field2'));
wp_localize_script ('my-script', 'MyFields', $my_field);
}
Now, in the script you have registered with the handle `my-script` you can access the variable with `MyFields.field1` and `MyFields.field2`. | stackexchange-wordpress | {

Styling the_posts_pagination With Font Awesome

How do I include js without register/enqueue?
I have some js which, rather than register and enqueue, I add directly to a page template.
Currently located outside of WP, I use
<script type="text/javascript" src="/apps/js/amplitude/amplitude.js"></script>
If I move it to a `js` folder inside my theme, how do I then include it in a template without hardcoding a root-relative path... can I use something like `get_template_directory_uri`? | Yes, you can use `get_template_directory_uri` to refer to the theme root path.
<script type="text/javascript" src="<?php echo get_template_directory_uri();?>/js/amplitude/amplitude.js"></script>

Remove h2 Tag in screen_reader_text
How can I remove the `h2` tag used in the screen reader text? I use the following `$args`, but h2 is still in it:
the_comments_pagination( array(
'add_fragment' => '',
'screen_reader_text' => __( '<h3>Test</h3>' )
) ); | There's a couple issues.
1) You're not supposed to put HTML inside most translations strings ( such as this ).
2) The `screen_reader_text` argument does not accept HTML at all, you need to filter the HTML by using the following hook:
`navigation_markup_template` \- Filters the navigation markup template.
/**
* Modify the given HTML
*
* @param String $template - Comment Pagination Template HTML
* @param String $class - Passed HTML Class Attribute
*
* @return String $template - Return Modified HTML
*/
function change_reader_heading( $template, $class ) {
if( ! empty( $class ) && false !== strpos( $class, 'comments-pagination' ) ) {
$template = str_replace( '<h2', '<h3', $template );
}
return $template;
}
add_filter( 'navigation_markup_template', 'change_reader_heading', 10, 2 );
The above searches the `$template` HTML string and replaces all `h2` tags with `h3` tags. | stackexchange-wordpress | {

Restrict submitters from wp-admin
Is it possible, if a subscriber wants to enter wp-admin, that the page would be rdirectet to any page I want ?

Are User Levels Still Currently Used?
I've migrated several sites from standalone installs into a Multisite install.
For the user table, I just recreated each new user individually one by one, and readjusted the user ID's accordingly elsewhere.
Upon investigating the user meta table, it seems that WordPress is creating keys for User Levels.
As mentioned in the Codex, it notes that User Levels were deprecated as of `WordPress 3.0`.
Why is it, that with a fresh installation of WordPress Multsite 4+, adding users, still creates "user_level" meta keys with values of such deprecated user level system?
Are user levels STILL used ANYWHERE in WordPress? or am I safe to simply just ignore those key/value pairs under the user meta table? | Many plugins (and themes) use user levels, you shouldn't use them in yours. They are still used in WordPress probably to offer backward compatibility with the huge number of plugins and themes that use them.

Apply custom css for user role

function admin_style() {
wp_enqueue_style('admin-styles', get_template_directory_uri().'/admin.css');
}
add_action('admin_enqueue_scripts', 'admin_style');
}
else {
}
how to modify the code to load also on front? btw, Is `if( current_user_can('seller', 'partner'))` correct for checking is user role is `seller` and `partner`? | To enqueue CSS in WordPress you can use:
* `wp_enqueue_scripts` action for the frontend
* `login_scripts` action for the login page
* `admin_scripts`action for the admin side, as you already know
To check user's roles you should get the user object and check the roles property. `current_user_can()` is function intended to check capabilities, not roles.
So, to add CSS based on user roles in the frontend:
add_action( 'enqueue_scripts', 'cyb_enqueue_styles' );
function cyb_enqueue_styles() {
$user = wp_get_current_user();
if( ! empty( $user ) && count( array_intersect( [ "seller", "partner" ], (array) $user->roles ) ) ) {

How do I technically prove that WordPress is secure?
One of my clients forces me to do their project without WordPress. But WordPress is the best for his requirements.
What he said is, WordPress is unsecure because WordPress is open source and everyone knows the code. So hacking chance is higher than with a custom website. That is the only thing he does not like about WordPress.
How do I prove that WordPress is secure even code is open for everyone? | Tell your client to read up on cybersecurity, because his premise is nonsense. Security through obscurity has been discredited since 1851 (yes, that's one and a half century ago). The opposite is also untrue. Open source software is not more secure than proprietary software.
The crucial thing in code security is not whether it's open or not, but whether it's well maintained. WordPress has an active community that is constantly alert on security matters. Follow the guidelines. Ask yourself how alert the authors of a rival cms are.

Creating posts from API data, how to identify posts already imported?
As the title says, I'm using an API to fetch some data which is used to create CPT posts, and need to identify items returned from the API which have already been inserted as posts.
The API returns unique IDs for each item, which naturally leads me toward just making use of the GUID column, but I've read, in no uncertain terms, to never make use of the GUID.
If touching the GUID is taboo, is there an accepted standard practice for doing this? Preferably without adding tables/columns to the database? | Never use GUIDs in WordPress, you definitely got that right.
However nothing prevents you use _concept_ of unique identifiers. You already have values for them, just ignore native column and store them in post meta as arbitrary data. On import you can check for that.

Saved emails at dashboard
I want to know if it's possible to send an email through a form in the website and then we can check that email in the normal email service (like gmail, etc) and the wordpress' dashboard.
Thanks | Yes. You can use Contact Form 7 plugin to create a form that will send messages to your email (like gmail, etc) and use another plugin from the same author, Flamingo, to have those messages saved in WordPress database and available in the dashboard.
If you prefer to avoid plugins, here's what you need:
1. Register non-public custom post type `message` to store submissions
2. Create custom html for your form (probably with js validation)
3. Intercept form submission on `init` hook
4. Validate and secure input
5. Create new post of `message` post type with `wp_insert_post()`
6. Send email with `wp_mail()`
7. Output results below the form (validation errors or success message)
As you see, plenty of work/code. If you're a developer, you should go this way to tailor it exactly for your needs. If not, I would strongly recommend you to use mentioned plugins (or any good alternatives) to avoid having some troubles with insecure form. | stackexchange-wordpress | {

Format content value from DB outside of WordPress filters
We're using WordPress to maintain data for a site that gets feed into a `JSON` file.
I've noticed that the post content we add to our file is not getting formatted appropriately. So when we feed it to our other website, the post content has no `HTML`, like paragraph tags.
I know that get_the_content runs the content through the WordPress filter to add all the correct `HTML` formatting. However, since we are making direct calls to the database in a custom script, we're just getting the raw post content.
What would we need to do in order to run our content through the WordPress content filter while our script is not connected to WordPress? | There are a few filters and actions here that run. You'd need to look at the code and figure out what/how to utilize these.

WP Mail isn't sending user account messages, does send from plugins
I'm running WP 4.6.1 and can't seem to send out any user account related emails. Specifically, notify user their account is created (the option is checked when creating accounts in the admin) and password reset emails don't send. No errors, just nothing shows in the receiver email account or spam. Email addresses are verified spelled correctly.
Interestingly, Gravity Forms and WooCommerce emails seem to be sent through fine (marked as spam, but at least they go through). The email notifying the administrator a new account has been created also does arrive.
I'm not using any SMTP or other email plugins at the moment, just WordPresses default mailer. The domain name is not on any blacklists, according to mxtoolbox.com.
Is there a hook or option I've overlooked that disables these emails? Any other ideas?
Thanks! | No, hooks have nothing to do here, all the emails you mentioned (WordPress Gravity Forms and WooCommerce) use the same function `wp_mail`.
I strongly believe this is blocked outside of WordPress, and I suggest you use a SMTP server with a real email address, you can use Postman SMTP Mailer/Email Log which will also help troubleshot emails related problems. | stackexchange-wordpress | {

Exclude custom post type from search conflict with get_posts
I want to hide my custom post type from search results. So, I followed the codex and used:
`exclude_from_search => 'true'` while registering my custom post type.
That hides the custom post type and it does not appear in search results any more.
But now I am unable to load posts using `get_posts` but they appear fine with `WP_Query`. I wonder why it is happening. | `get_posts()` uses `WP_Query`, so you are probably providing wrong arguments, it's worth mentioning that the function has some default arguments.

'post_status' => 'any',

Conditionally loading JavaScript based on the Advanced Custom Fields in the post
I am building a site/theme where post content is authored in a modular way (mostly, but not exclusively) with ACF's flexible content field. These fields could have JavaScript functionality attached to them on the public front-end. You might have an image upload that has parallax applied to it or a text block that has a click or hover animation applied to it, for example. I'm trying to determine the most useful method for conditionally loading the different JavaScript libraries that might power this functionality (in the post, as the public sees it, I'm not talking about the admin side). Specifically I'm trying to avoid always loading everything, instead I'm hoping to load specific libraries based on the fields actually present in the post. Is there an established way, outside of the brute force method of looping through the content multiple times to first check for fields and then later to display them? | ACF has finegrained filters for fields when they get loaded.
add_action( 'wp_enqueue_scripts', 'register_my_scripts', 5 );
function register_my_scripts() {
wp_register_script( 'my-script', 'path-to/my-script.js', array(), 'version', true );
}
add_filter('acf/load_field/name=my_field_name', 'load_field_my_field_name');
function load_field_my_field_name( $field ) {
wp_enqueue_script( 'my-script' );
return $field;
}
Normally all scripts should be enqueued in `wp_enqueue_scripts` hook. So you should make sure your script and its dependencies (which haven't been loaded yet) can be loaded in footer. Like this your script gets enqueued when the fields are accessed in the content. | stackexchange-wordpress | {

Creating custom pages for new users automatically
I am new here and I have a few questions about Wordpress functionality or functionality that I can add through plugins.
Here is what I am trying to accomplish:
1. When a new user signs up, a new page is automatically created, with the page name being the person's user name
2. I would like to beable to add custom sign up fields, and call to it on their new page. For example "Favorite food"
3. On this new page, I would like to make a call to the new field. I would like to show one sentence on the page. For example "My favorite food is potatoes."

How to have custom post type /example/ and then posts /example/posts.html
I have multiple custom post types and all of them have to have their own "homepage". The url of this homepage is very important and **must be the same with part of the url of the individual posts**. For example:
example.com/custom-post-type/ <- the homepage for this custom post type
example.com/custom-post-type/title-for-a-post/ <- show the page for a post in that custom post.
The issue is that I am getting url conflicts and wp does not run the right templates. I cannot have an empty url for custom-post-type/ so I tried creating a different custom post type and removed the slug. But this is also causing it to render the wrong templates.
Any idea how to approach it? Each custom post type has radically different templates and fields.
Thanks! | This is exactly how wordpress works.
For each Custom Post type Create an archive-custom_post_type_name.php and a single-custom_post_type_name.php
Wordpress automatically loads that file when someone goes to the url.
so if your custom posts types were koolio and notsokool then you would need these 4 files in your theme child (you're using a child theme, right?!)
archive-koolio.php single-koolio.php archive-notsokool.php single-koolio.php
I would take the single file out of your theme folder and copy it to your child them, then add the CPT extension. Do the same for the archive template.
rememeber you'll have to flush the re-write rules if your plugin isn't set to do this by itself...just go to seetings/permalinks and hit save. | stackexchange-wordpress | {

How to save html and text in the database?
I have two fields. The first is for plain text (but with special characters) and the second for html content (wp_editor is used). Both are later needed for phpmailer.

wp_editor( $epn_doi_body, 'doi-body', array( 'editor_height' => '300px' ) );
1) How do i correctly secure them after submitting the form and then save them in the database into a custom table that already exist? (esc_attr, sanitize_text_field ...)
2) And when i want to output the content from the database in the exact and original typed version: How do i make this? (wpautop ...)

wp_editor( $epn_doi_body, 'doi-body', array( 'editor_height' => '300px' ) );
To get the same result that was saved to the database the output has to be modified.
For the textarea:

Why does get_post() not return anything?
Inside my functions.php I use `get_post()` or similar (such as `get_the_title()`) inside some of my functions. It does not return anything. Why? And how to fix that?
P.S: And I can not really add `add_action('somehook', 'myfunc')`, because that makes things display in the wrong place. | When `$post` is null for `get_post` it looks to `$GLOBALS['post']`.
There are several other checks in the source so perhaps you should find out the value of the global variable when you're calling it or give it something besides and empty value.
What does `get_the_id()` return vs. `get_post(get_queried_object_id())`? Or `var_dump(get_queried_object())`?

how to use Data URI for images in WP?
I have a HTMl file that should converted to WP and WooCommerce.

Or even the broader question... Is it wise to use data URI in this context ?
Thanks. | Data URIs don't cache. So you have the same overhead each page request instead of allowing the user to cache those image requests. For product and banner images it doesn't make much sense to take extra processing power to convert them on the fly (each request) or pre-process them which means they'll be stored in the database.

How does mediaelement.js work in WordPress?

I'm developing a theme and video player doesn't seem to be working properly. Should mediaelement.js be included in footer.php or header.php in order to make the [video] shortcode work in template? | WordPress core handles the enqueuing of the MediaElement.js scripts and styles automatically when the `[video]` shortcode is used:

Modify RSS - remove image and add text

<content:encoded>![CDATA{ <img src="{imgpath}" alt="{imgAlt}"/>{postExcerpt}...{link}{link}<a href="">Read more</a> at]]>
Why does this happen? I followed the instructions at Remove images from get_the_excerpt but it still shows images and the extra text is formatted strangely. | Note that `the_permalink_rss()` and `the_excerpt_rss()` do **echo** the output, **not return** it.

and replace `the_permalink_rss()` with:
esc_url( apply_filters( 'the_permalink_rss', get_permalink() ) );

<a href="<?php the_permalink_rss(); ?>">

<?php the_permalink_rss(); ?>
?>]]></content:encoded>
where you strip the RSS excerpt through the `the_excerpt_rss` filter or use the above approach to get the excerpt output to strip it.

Function not working on any file other than the main plugin file
My plugin has several php files that are included on the main plugin file. I am using some functions on the other files but they don't work there. They work when I use them on the main plugin file.
For example,
**On the main plugin file _"test-plugin.php"_**
<?php
/*
Plugin Name: Test Plugin
Description: test
Version: 1.0
*/
include_once( plugin_dir_path( __FILE__ ) . 'test-file.php' );
**On the other file _"test-file.php"_ (same directory with test-plugin.php)**
<?php
function enable_user_registration() {
if(!get_option('users_can_register')) {
update_option( 'users_can_register', '1' );
}
}
register_activation_hook( plugin_dir_path(__FILE__), 'enable_user_registration' );
Regards.. | I guess you should be using `register_activation_hook()` with the full path including filename, not just the path:
register_activation_hook( plugin_dir_path(__FILE__) . 'test-plugin.php', 'enable_user_registration' ); | stackexchange-wordpress | {
