How can I remove the Wordpress-Version (?ver=5.x) from my plugin

Question

I am working on my first plugin that adds a external script to the footer. Wordpress automatically adds the version number at the end, which I'm trying to remove. What I have so far:

add_action('wp_enqueue_scripts', array($this,'print_code'));

public function print_code(){
         
        $location   =   get_option('location_select');
        $url        =   'https://' . esc_html($location) . '.domain.com/js/script.js';
        wp_enqueue_script('myID', $url, array('jquery'), false, true);


     }

This puts out the script correctly, but I still have the version (?ver=5.8) at the end. The false should avoid that, afaik. What am I missing?

Answer 1

Change the 4th parameter from false to null.

wp_enqueue_script( 'myID', $url, array( 'jquery' ), null, true );

From the wp_enqueue_script() documentation:

$ver
(string|bool|null) (Optional) String specifying script version number, if it has one, which is added to the URL as a query string for cache busting purposes. If version is set to false, a version number is automatically added equal to current installed WordPress version. If set to null, no version is added.

As defined in the codex,

If version is set to false, a version number is automatically added equal to current installed WordPress version. If set to null, no version is added.

You're currently setting false. You should be setting null:

wp_enqueue_script('myID', $url, array('jquery'), null, true);
