register_deactivation_hook argument -> pass arguments in the selected function

Question

I've been looking for minutes how to pass arguments in the register_deactivation_hook as follow :

register_deactivation_hook( __FILE__, array( new Cpt, 'delete_cpt') ) );

class Cpt
{
    /**
     * Delete a custom post type
     */
    public function delete_cpt($name = 'test') {
        /**
         * delete a single data
         */
        require_once( ABSPATH . 'wp-admin/includes/upgrade.php' );
        $GLOBALS['wpdb']->delete( 
            'cpt', 
            array( 
                'name'=>$name 
            ) 
        );
        $GLOBALS['wpdb']->show_errors();
        echo $GLOBALS['wpdb']->last_query;
        echo $name;
        die();
    }
}

The function executes but the $name var remains empty. I would like to pass the $name directly in register_deactivation_hook;

Is it at least possible ? Nothing seen anywhere.

Answer 1

Use a complete function as callback, so you can pass the argument to the method. Example:

register_deactivation_hook( 
    __FILE__,
    function() {
        $cpt = new Cpt;
        $cpt->delete_cpt( 'post_type_name' );
    }
);

Answer 2

You could create a static method inside your Cpt class and call that instead with register_deactivation_hook; Then you create your object and send it data as usual.

Answer 3

You should replace the register_deactivation_hook code line with below code:

register_deactivation_hook( __FILE__, array( 'Cpt', 'delete_cpt' ) );
