admin_print_footer_scripts filter

Prints any scripts and data queued for the footer.

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

We at Flipper Code, 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 modify_admin_print_footer_scripts_defaults and we registered using add_filter. The first parameter admin_print_footer_scripts is name of the hook, The second parameter modify_admin_print_footer_scripts_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove admin_print_footer_scripts filter.


  • No parameters

Live Example

function admin_footer_js(){
    //you should check to make sure this is the page your want to alter first, check if this your custom post edtit page
    // for example .wp-admin/edit.php?post_type=my-cpt would be your custom post table list page.
    if(!isset($_GET['post_type']) || false === strpos($_GET['post_type'],'my-cpt') ){
        return false;
    //get_current_screen() can result in fatal error on some admin pages, hence I use it after a basic check above
        $screen = get_current_screen();  
        if ( 'edit' != $screen->base && '' != $screen->action ){
   ) . ';';

Below is an example how you can use this hook.

                        function modify_admin_print_footer_scripts_defaults() { 
                            // Update the $option variable according to your website requirements and return this variable. You can modify the $option variable conditionally too if you want.

                            return $option; 
                        // add the filter
                        add_filter( "admin_print_footer_scripts", "modify_admin_print_footer_scripts_defaults");

To remove a hook callback, use the example below.

remove_filter( "admin_print_footer_scripts", "modify_admin_print_footer_scripts_defaults");

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