Use of wp_print_footer_scripts hook in WP

The wp_print_footer_scripts hook in WordPress allows developers to add custom scripts or code to the footer of their website. This is particularly useful for including JavaScript or other functionality that needs to be loaded after the main content of the page.

Here’s how you can use the wp_print_footer_scripts hook:

• Understanding the Hook:The wp_print_footer_scripts action is triggered inside the wp_footer action.
• It provides no parameters.
• Your custom function should echo output directly to the browser or perform background tasks. It shouldn’t return any values or take parameters.
• Adding Your Custom Script:Define your custom function that contains the JavaScript code you want to include in the footer.
• Use the add_action function to hook your custom function to wp_print_footer_scripts.
• For example:

function print_my_script() {
    echo '<script>
        // Your custom script here
    </script>';
}
add_action('wp_print_footer_scripts', 'print_my_script');

• In the above example, replace // Your custom script here with your actual JavaScript code.
• Priority and Execution Order:By default, the wp_print_footer_scripts hook executes at the same priority level as other scripts enqueued using wp_enqueue_script.
• If you want to control the execution order, you can specify a priority as the third argument to add_action. Higher numbers result in later execution.

add_action('wp_print_footer_scripts', 'print_my_script', 100);

• Enqueued scripts are executed at priority level 20, so setting a higher priority will ensure your custom script runs after enqueued scripts.

Note that this hook is theme-dependent, so its availability depends on the theme you’re using. Most plugins bind their script files or functions to this hook, making it an essential part of WordPress theming.
