How to use parse_request action in WordPress

parse_request action

Fires once all query variables for the current request have been parsed.

To use the parse_request action, first you have to register it using add_action. 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 execute_on_parse_request_event which takes one parameter and we registered it using add_action. The first parameter parse_request is the name of the hook, the second parameter execute_on_parse_request_event 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 in the registered function.

Sometimes, you have to remove a registered hook, so you can use remove_action to remove the parse_request action.

Parameters

Below is the one parameter required to use this hook.

• $wp : (WP) Current WordPress environment instance (passed by reference).

Live Example 1: Change Posts Per Page for Custom Post Type

Below is an example of how you can use this hook to change the number of posts displayed per page for a custom post type.

    add_action( 'parse_request', 'weplugins_change_post_per_page' );
    function weplugins_change_post_per_page( $query ) {
        if ( 'my_cpt' == $query->query_vars['post_type'] ) {
            $query->query_vars['posts_per_page'] = 3;
        }
        return $query;
    }
    

Live Example 2: Custom Function Execution on parse_request

Below is an example of how you can execute a custom function when the parse_request action is triggered.

    function weplugins_execute_on_parse_request_event($wp) {
        // You can write code here to be executed when this action occurs in WordPress.
        // Use the parameters received in the function arguments & implement the required 
        // additional custom functionality according to your website requirements.
    }
    // add the action
    add_action( "parse_request", "weplugins_execute_on_parse_request_event" , 10, 1);
    

Live Example 3: Removing a Hook Callback

To remove a hook callback, use the example below.

    remove_action( "parse_request", "weplugins_execute_on_parse_request_event", 10, 1 );
    

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