I have written a small class that will handle enqueues in my theme :


class Header {

    public function init_hooks()
        add_action('wp_print_scripts', array(__CLASS__,'include_all_files'));

    public function include_css_files()
        wp_register_script('style.css', get_bloginfo('stylesheet_url'));

    public function include_js_files()
        wp_register_script('jquery-min', "http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js");

    public function include_all_files()



I call it right before closing the head tag, like :

$header = new Header();

But it does not work. There is no error, but no script is added. Any ideas ?

You're code is running after scripts have been output(you said just before the closing <head> tag, that's too late for the enqueues. The code needs to run before wp_head() does.. – Mark Duncan Jun 30 '11 at 11:06

You mean you call your class right before closing HTML tag? It is too late to enqueue scripts then.

Don't hook into wp_print_scripts to enqueue your scripts and styles. I just learned this today from Rarst.

So change your init_hooks function to something like following:

public function init_hooks()
    add_action('wp_enqueue_scripts', array(__CLASS__,'include_all_files'));

Also you are using wp_register_script and wp_enqueue_script functions to enqueue your styles, Wordpress has separate functions to enqueue your styles wp_register_style and wp_enqueue_style. Your include_css_files should look like:

public function include_css_files()
    // NOTE: you don't really have to use the filename as style slug.
    wp_register_style('my_style', get_bloginfo('stylesheet_url'));

Now about instantiating your class and calling init_hooks. You can either place it directly inside your functions.php, or you can use the init action to instantiate your class.

very helpful thank you :) – SpyrosP Jun 29 '11 at 5:15
you are welcome – Hameedullah Khan Jun 29 '11 at 5:17
just a small side question. I can't get the style to print without having something like "wp_print_scripts('style.css');" explicitly. Is this normal ? It does not like normal to me :/ – SpyrosP Jun 29 '11 at 5:35
Oops.. sorry I missed you are using wp_register_script and wp_enqueue_script to register and enqueue your styles. There are separate functions for styles, wp_register_style and wp_enqueue_style. See codex.wordpress.org/Function_Reference/wp_enqueue_style and codex.wordpress.org/Function_Reference/wp_register_style – Hameedullah Khan Jun 29 '11 at 6:45
