Ok, I figured it out.
Just wrote a small plugin adding the “newzik” protocol :
<?php
/**
* Plugin Name: NZK links support
* Plugin URI: http://newzik.com/
* Description: Adds support to newzik:// links
* Version: 1.0
* Author: Pierre Mardon
* Author URI: http://newzik.com/
* License: None
*/
/**
* Extend list of allowed protocols.
*
* @param array $protocols List of default protocols allowed by WordPress.
*
* @return array $protocols Updated list including new protocols.
*/
function wporg_extend_allowed_protocols( $protocols ){
$protocols[] = 'newzik';
return $protocols;
}
add_filter( 'kses_allowed_protocols' , 'wporg_extend_allowed_protocols' );
?>
Just removed the tags above so that my question makes sense 🙂
