How to use admin_email_check_interval filter in WordPress

To use the admin_email_check_interval filter, you need to register it using add_filter. You can include this code in the functions.php file of your active theme or, even better, in a custom WordPress Plugin. This way, when you update your theme, everything stays intact. Using a custom plugin is a best practice we follow at WePlugins.

Below are some live examples of how you can manipulate this hook:

Example 1: Lowering the Admin Email Check Interval

In this example, we will reduce the default admin email check interval from 6 months to 3 months.

    /**
     * Lower the admin email check interval down to 3 months.
     */
    add_filter( 'admin_email_check_interval', static function ( $interval ) {
        // Check if the interval has the default value of 6 months and if so, lower it to 3 months.
        if ( 6 * MONTH_IN_SECONDS === $interval ) {
            $interval = 3 * MONTH_IN_SECONDS;
        }
        // Return the adjusted interval.
        return $interval;
    } );
    

Example 2: Customize the Interval

Here’s how you can customize the interval according to your website’s needs.

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

Example 3: Removing the Filter

To remove a hook callback, use the example below. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.

    remove_filter( "admin_email_check_interval", "weplugins_modify_admin_email_check_interval_defaults", 10, 1 );
