How to use automatic_updates_debug_email filter in WordPress

When working with WordPress, you often need to fine-tune and customize various functionalities. One such hook is the automatic_updates_debug_email filter. This hook filters the debug email that can be sent following an automatic background core update.

To use the automatic_updates_debug_email filter, you first need to register it using add_filter. You can write this code into the functions.php file of your activated theme or in a custom WordPress Plugin. At WePlugins, we always prefer creating a custom WordPress Plugin when using hooks so nothing breaks when you update your WordPress Theme in the future.

Let’s dive into some live examples of how to use this hook effectively.

Example 1: Basic Usage

This example demonstrates how to modify the default debug email settings.

    function weplugins_modify_automatic_updates_debug_email_defaults($email, $failures, $results) { 
        // Update the $email variable according to your website requirements and return this variable.
        // You can modify the $email variable conditionally too if you want.
        return $email; 
    }
    // Add the filter
    add_filter("automatic_updates_debug_email", "weplugins_modify_automatic_updates_debug_email_defaults", 10, 3);
    

Example 2: Custom Email Subject

In this example, we modify the subject of the debug email.

    function weplugins_custom_debug_email_subject($email, $failures, $results) {
        $email['subject'] = 'Custom Debug Email Subject after Automatic Updates';
        return $email;
    }
    // Add the filter
    add_filter("automatic_updates_debug_email", "weplugins_custom_debug_email_subject", 10, 3);
    

Example 3: Removing the Hook

To remove a registered hook, use the following example.

    // Remove the filter
    remove_filter("automatic_updates_debug_email", "weplugins_modify_automatic_updates_debug_email_defaults", 10, 3);
    

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