What is WordPress Hook: rest_pre_dispatch
The rest_pre_dispatch hook in WordPress is used to intercept and modify the response to a REST API request before it is returned. This hook allows developers to manipulate the data being sent back to the client, making it a powerful tool for customizing the behavior of REST API endpoints.
Understanding the Hook: rest_pre_dispatch
The rest_pre_dispatch hook is located within the REST API request handling process in WordPress. It is triggered just before the response to a REST API request is sent back to the client, giving developers the opportunity to modify the data or perform additional processing.
Hook Parameters (if applicable): rest_pre_dispatch
The rest_pre_dispatch hook does not accept any parameters.
Hook Doesn’t Work: rest_pre_dispatch
If the rest_pre_dispatch hook doesn’t seem to be working as expected, it could be due to conflicts with other plugins or themes that are also modifying the REST API response. It’s important to check for any other code that might be interfering with the hook and causing unexpected behavior.
Best Practices & Usage Notes (if applicable): rest_pre_dispatch
When using the rest_pre_dispatch hook, it’s important to keep in mind that any modifications made to the response data will affect all requests to the corresponding REST API endpoint. It’s also important to thoroughly test any modifications to ensure they don’t inadvertently break the functionality of the API.
Usage Example: rest_pre_dispatch
“`php
add_action( ‘rest_pre_dispatch’, function( $result, $server, $request ) {
// Modify the $result data before it is sent back to the client
$result[‘modified’] = true;
return $result;
}, 10, 3 );
