How to use admin_print_footer_scripts-hook_suffix action in WordPress

admin_print_footer_scripts-hook_suffix action

The dynamic portion of the hook name, $hook_suffix, refers to the global hook suffix of the current page.

To use admin_print_footer_scripts-hook_suffix action, first you have to register it using add_action. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

At WePlugins, we 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 weplugins_execute_on_admin_print_footer_scripts_hook_suffix_event and we registered it using add_action. The first parameter admin_print_footer_scripts-hook_suffix is the name of the hook. The second parameter weplugins_execute_on_admin_print_footer_scripts_hook_suffix_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 admin_print_footer_scripts-hook_suffix action.

    }
    add_action("admin_print_footer_scripts-hook_suffix", "weplugins_execute_on_admin_print_footer_scripts_hook_suffix_event");

    // To remove the action
