How to use oembed_request_post_id filter in WordPress

WordPress hooks are an amazing way to tap into and modify the inner workings of WordPress without editing core files. Today, we’re diving into the oembed_request_post_id filter. This filter is used to determine the post ID for an oEmbed request. Let’s explore how you can use it effectively in your WordPress projects.

oembed_request_post_id filter

Filters the determined post ID.

To use the oembed_request_post_id filter, you first have to register it using add_filter. You can write this code into the functions.php of your activated theme or in a custom WordPress Plugin. We at WePlugins, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_oembed_request_post_id_defaults which takes 2 parameters, and we registered it using add_filter. The first parameter oembed_request_post_id is the name of the hook, the second parameter modify_oembed_request_post_id_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed to the registered function.

Sometimes, you have to remove a registered hook, so you can use remove_filter to remove the oembed_request_post_id filter.

Parameters

Below are the 2 parameters required to use this hook.

• $post_id: (int) The post ID.
• $url: (string) The requested URL.

Example 1: Basic Use

Below is an example of how you can use this hook.

    function weplugins_modify_oembed_request_post_id_defaults($post_id, $url) {
        // Update the $post_id variable according to your website requirements and return this variable. You can modify the $post_id variable conditionally too if you want.
        return $post_id;
    }
    // add the filter
    add_filter("oembed_request_post_id", "weplugins_modify_oembed_request_post_id_defaults", 10, 2);
    

Example 2: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_filter("oembed_request_post_id", "weplugins_modify_oembed_request_post_id_defaults", 10, 2);
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.

Example 3: Conditional Modification

Sometimes, you may want to modify the post ID only for specific URLs. Below is an example of how you can achieve this:

    function weplugins_conditional_oembed_request_post_id($post_id, $url) {
        if (strpos($url, 'example.com') !== false) {
            $post_id = 123; // Set a specific post ID for URLs from example.com
        }
        return $post_id;
    }
    add_filter("oembed_request_post_id", "weplugins_conditional_oembed_request_post_id", 10, 2);
