The first PHP file that WordPress loads and doesn't overwrite on update is wp-config.php. At this point, WordPress is not loaded. So you can put your functions at the beginning of that file.

init is not the first action to run on a WordPress install. Here is a basic rundown of a typical stack order.
https://codex.wordpress.org/Plugin_API/Action_Reference
Try hooking into `muplugins_loaded'. I don't believe it is conditional, so it should run every time.

Try :
add_filter( 'woocommerce_checkout_fields' , 'custom_override_checkout_fields' );

}
return $fields;

I like the idea of running this through a schedule event in WordPress, https://codex.wordpress.org/Function_Reference/wp_schedule_event
Here is a snippet that hopefully will get you there:

wp_schedule_event( time(), 'daily', 'daily_plugin_check' );
}

You can mange this by adding the following to your functions.php file.
Checking todays timestamp for the days you want the plugin active - on the off days the plugin is disabled.
$timestamp = time(); // Timestamp
$day = date( 'D', $timestamp ); // Get day from timestamp
$active = array( 'Mon', 'Wed', 'Fri', 'Sat' ); // Days plugin to be active

What about using WordPress Options API to store a flag whether it is the first switch or not:

if(get_option('first_theme_activation') === false){

php.net defines this as
(PHP 4, PHP 5, PHP 7) function_exists — Return TRUE if the given function has been defined
I have to agree with Michelle in usage in that you [sh]ould only use the check for something similar to type cast checking; so you would be looking for if a function existed (on that page or from anything called on that page/file reference) ...

There is a filter, wp_audio_extensions, that should allow you to add m3u8 to the whitelist of allowed file extensions. Add this code to a child theme's functions.php file, or using a plugin like Code Snippets:
function wpse_341199_allow_m3u8_extension( $exts ) {
$exts[] = 'm3u8';
return $exts;

You have to replace $post_id with get_the_id();

What you're trying isn't possible with WP_Query.
The reason is that because you have only stored the duration, it's not possible to tell whether a post has expired until you know the publication date and the duration time and add them together. That's what this does:
$expire = get_field( 'status_time_duration' ) + get_the_time( 'U' );
That code relies in ...

There's no permalink property of a product. Permalinks are not stored in the database, because they're generated based on a number of external factors. Therefore you need to use a function to retrieve the permalink. In WooCommerce the best way to do this is with:
function fpd_custom_order_item_values($_product) {
$url = $_product->get_permalink();

The code that you have shared points towards wp-vcd malware in your WordPress website. The main symptom of wp-vcd malware are spam popups, creates Spam URLs on the website.

Maybe your hook called too early. And after yours, this connection time changes elsewhere. Try to increase priority like that:
add_filter( 'auth_cookie_expiration', 'keep_me_logged_in', 99, 3);
function keep_me_logged_in( $expiration, $user_id, $remember ) {/*your code*/}

Tested with Wordpress 5.0.4
The first problem to solve it's the post_name value for pages that would share the same slug (e.g. about-me).
The simpler solution I found is to add the author nicename (beware: in my solution it should not contain a hyphen!) as the first part of the slug:
about-me page post_name for john: john-about-me
about-me page post_name ...

If it's just a list of numbers, I'd suggest just saving them in a text file, with a number on each line.

Then when you need the file, read its contents with PHP, and use preg_split() to turn it into an array:

My include has a handful of custom hooks which handle enqueuing, dequeuing and inserting custom HTML.
I'm still not 100% certain what you mean, but if this code is normal WordPress code, with functions and add_action(), and you only want those hooks to run on these events pages, then the proper way to do this would be to include that file into your theme's ...

Say that get_author_posts_url(1) return the following URL
https://example.com/author/admin/
Passing the $author_nicename will change this. So get_author_posts_url(1, 'foo') will result in
https://example.com/author/foo/
You can also check this in the source code of get_author_posts_url().
So what does passing the second argument do? It changes the ...

You should be able to change create_function( '$a', "return null;" ) to Anonymous Function (aka Closure) :

There is an inbuilt function for returning null: __return_null.
So you can replace create_function('$a', 'return null;'); with just '__return_null' (note the quotes) as it seems $a is not used anyway.
Or you can use an anonymous function as the argument directly: function($a) {return null;} (no quotes). Either way since the argument is expecting a ...

This answer assumes you are using WooCommerce version 3.0 or newer.

Here is a solution to upload a copy of the image saved as a URL in a custom field into a local directory on your site. This will not add the image to the media library and is meant as more of a caching mechanism.
You should always be sure that you have permission to use images from other sources before you use them. Only use this code for good!

has_category() only tells you if a specific post has a given category (or any category, if none is provided). You can tell it which post to check by passing the post ID as the second argument. When used inside the loop however, you can omit the post ID and it will check the current post.
The problem is that if it's used outside the loop, then the 'current ...

As long as has_category is used within the loop then it should work when used within index.php, archive.php, etc. You will likely run into issues if it is used outside of the loop on those templates.

You can create a custom shortcode wrapper that will execute the shortcode with the desired attributes, so you would use [jobs-custom] in the page:

The reason you're not finding a quick fix is that there isn't a consistent way to hide header and footer content across all templates, across all themes. Also, even builders like Elementor require the ability to enqueue their own CSS and JS. If you completely remove the header and footer, you will almost always also be completely removing the necessary hooks,...

It is bad practice to end a PHP only file with the PHP closing tag (?>) as it may lead to a new line or any other character being output before the headers or other functions and thus creating problems like the one you mention.
Whenever you create/edit a PHP file, don't close it, if you have to include HTML, close and open the PHP tags again.

I believe the most direct way of customizing WordPress feeds is to hook into them directly with the following filter.

you could try to use this:
add_filter('body_class', 'custom_body_class');
function custom_body_class($classes) {
global $post;
if ($post->ID == 346) {
$classes[] = 'services';
}
return $classes;
}
This can be used anywhere as its pulling the global variable first.

What you're looking to accomplish isn't really pagination. That threw me off initially. You're building a navigation that will be site-wide.
If that's the case, you can either capture the ID from the url (this is not very performant) or add the ID to the markup.
This example shows you how to add the ID as a data attribute on the menu's anchor tag:

ob_start();
get_template_part($atts['path']);
