wp_enqueue_scripts hook is not being called

2 Views

I added the following code to my functions.php: 

if(!function_exists('bi_frontend_scripts')) {
    function bi_frontend_scripts() {
        wp_enqueue_script('jquery');
        // I originally wanted to do:
        wp_enqueue_script('jQuery.bxSlider', get_bloginfo('template_url').'/scripts/jquery.bxslider/jquery.bxslider.min.js', array('jquery'));
    }
}
add_action('wp_enqueue_scripts', 'bi_frontend_scripts');

But apparently neither of the scripts is being enqueued. I didn’t get what my problem was, so I added this script to find out if the hook is called:

function aal_handler() {
    static $list = array();
    // exclude certain actions:
    $exclude = array('gettext', 'gettext_with_context');

    $action = current_filter();

    if(!in_array($action, $exclude)) {
        $list[] = $action;
    }
    // shutdown is the last action
    if ('shutdown' == $action) {
        print '<pre>' . implode( "n", $list ) . '</pre>';
    }
}
add_action('all', 'aal_handler', 99999, 99);

And in the list wp_enqueue_scripts does not appear. So why the hook is not called?!

  1. Your code is correct, though I would not add the callback if the function name has already been used. If someone else has used the name you don’t know what you might be adding.

    if(!function_exists('bi_frontend_scripts')) {
    function bi_frontend_scripts() {
        wp_enqueue_script('jquery');
        // I originally wanted to do:
        wp_enqueue_script('jQuery.bxSlider', get_bloginfo('template_url').'/scripts/jquery.bxslider/jquery.bxslider.min.js', array('jquery'));
    }
    add_action('wp_enqueue_scripts', 'bi_frontend_scripts');
}

    I also tested your “hook dump” function– aal_handler()— and that works. wp_enqueue_scripts is part of the output.

    I have to conclude that there is something wrong with the theme. wp_enqueue_scripts is hooked to wp_head, which fires in the wp_head() function. The most obvious possibility is that your theme is not using wp_head() correctly, or at all. Another distant possibility is that something has removed your callback– for example, with:

    remove_all_filters('wp_enqueue_scripts');

  3. I am here again with a lot of information for you so that you understand how things work with wp_enqueue_scripts.

    You need to know the priority order for the wp_enqueue_scripts. See hook order below:

    1. muplugins_loaded
    2. registered_taxonomy
    3. registered_post_type
    4. plugins_loaded
    5. sanitize_comment_cookies
    6. setup_theme
    7. load_textdomain
    8. after_setup_theme
    9. auth_cookie_malformed
    10. auth_cookie_valid
    11. set_current_user
    12. init
    13. widgets_init
    14. register_sidebar
    15. wp_register_sidebar_widget
    16. wp_default_scripts
    17. wp_default_stypes
    18. admin_bar_init
    19. add_admin_bar_menus
    20. wp_loaded
    21. parse_request
    22. send_headers
    23. parse_query
    24. pre_get_posts
    25. posts_selection
    26. wp
    27. template_redirect
    28. get_header
    29. wp_head
    30. wp_enqueue_scripts
    31. wp_print_styles
    32. wp_print_scripts

    …and so on.

    So you see you can add it in the init hook and doing so it will be called as high priority than below the listing.

    If your files are not loading you could use a higher priority hook.

    If your wp_enqueue_script is not being called, you can use this simple trick to get it working for your theme or plugin.

    <?php

if(!function_exists('bi_frontend_scripts')) {
    function bi_frontend_scripts() {
        wp_enqueue_script('jquery');
        // I originally wanted to do:
        wp_enqueue_script('jQuery.bxSlider', get_bloginfo('template_url').'/scripts/jquery.bxslider/jquery.bxslider.min.js', array('jquery'));
    }

    add_action( 'init', 'bi_frontend_scripts' );
}
