How to use get_header_video_url filter in WordPress

Hey there! If you’re looking to get your hands dirty with WordPress hooks, you’ve come to the right place. As an Indian developer, let me walk you through how to use the `get_header_video_url` filter. This hook is super handy for filtering the header video URL in WordPress. You can register it in your `functions.php` file or, better yet, create a custom WordPress plugin to keep things neat and future-proof. Let’s dive in!

Example 1: Modifying the Header Video URL

In this example, we define a function `weplugins_modify_get_header_video_url_defaults` that takes one parameter. We then register this function using `add_filter`. The hook name is `get_header_video_url`, and our custom function will modify the URL as needed.

   function weplugins_modify_get_header_video_url_defaults($url) {
       // Update the $url variable according to your website requirements and return this variable. You can modify the $url variable conditionally too if you want.
       return $url;
   }
   // add the filter
   add_filter("get_header_video_url", "weplugins_modify_get_header_video_url_defaults", 10, 1);
   

Example 2: Conditional Modification

Sometimes, you might want to modify the video URL based on specific conditions. In this example, we’ll show you how to do that.

   function weplugins_modify_get_header_video_url_conditionally($url) {
       if (is_front_page()) {
           $url = 'https://example.com/front-page-video.mp4';
       }
       return $url;
   }
   // add the filter
   add_filter("get_header_video_url", "weplugins_modify_get_header_video_url_conditionally", 10, 1);
   

Example 3: Removing the Filter

If you ever need to remove the filter, you can use the `remove_filter` function. Just make sure to provide the same callback function name, priority, and number of arguments.

   // remove the filter
   remove_filter("get_header_video_url", "weplugins_modify_get_header_video_url_defaults", 10, 1);
