The wp_enqueue_scripts function is a useful tool for WordPress developers to efficiently load JavaScript files on their websites. By utilizing this function, you can ensure that your scripts are loaded properly, without any dependencies or version issues.

Below is an example of implementing wp_enqueue_scripts in the functions.php file:

// Enqueue scripts and styles using wp_enqueue_scripts hook
function custom_scripts_and_styles() {
    // Deregister the default jQuery core script
    wp_deregister_script('jquery-core');

    // Register jQuery from an external source
    wp_register_script('jquery-core', '//ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js');

    // Enqueue custom script depending on the registered jQuery
    wp_enqueue_script('custom-script', get_template_directory_uri() . '/js/custom-script.js', array('jquery'), '1.0', true);

    // Enqueue the default jQuery script
    wp_enqueue_script('jquery');

    // Enqueue custom style
    wp_enqueue_style('custom-style', get_stylesheet_directory_uri() . '/css/custom-style.css', array(), '1.0', 'all');
}
add_action('wp_enqueue_scripts', 'custom_scripts_and_styles');

Explanation of Code:

In the provided code snippet, we have a function custom_scripts_and_styles() that is hooked to the wp_enqueue_scripts action in WordPress. Let’s break down this code in detail:

  • Deregistering and Registering jQuery:
    • wp_deregister_script('jquery-core'): This function deregisters the default jQuery core script to prevent conflicts or redundancies.
    • wp_register_script(...): Here, jQuery is registered from an external source, specifically from the Google CDN, with version 3.5.1.
  • Enqueuing Custom Script:
    • wp_enqueue_script(): This line enqueues a custom script named ‘custom-script’ located in the theme’s ‘js’ directory. It has a dependency on the registered jQuery script, version ‘1.0’, and is set to load in the footer of the webpage for optimized performance.
  • Enqueuing Default jQuery Script:
    • wp_enqueue_script('jquery'): The default jQuery script is enqueued, ensuring that jQuery is available for use in the WordPress site.
  • Enqueuing Custom Style:
    • wp_enqueue_style(...): This line enqueues a custom style sheet named ‘custom-style’ located in the theme’s ‘css’ directory. It has version ‘1.0’ and is set to be applied to all media types (‘all’).

By using the wp_enqueue_scripts hook along with wp_enqueue_script, you can efficiently manage script loading, dependencies, and versions, optimizing your website’s performance.
