Adding a wp_head hook from an included PHP file

Question

I am using a WordPress plugin for including PHP code within posts and pages, and it's working great - however, I need to insert some styles and scripts, and in order to do that, I need to add a hook to wp_head. I tried it, creating a function and using add_action('wp_head','my_func'); but it didn't work - my stuff is not being included.

I think its because wp_head is being called before my script it being included.

I would like to do this without changing any of my themes files.

Is there any way to do this? I am using the latest WordPress version.

To enqueue styles and scripts properly, use the wp_enqueue_scripts action like so:

function wpa_63708_enqueue_scripts() {
    wp_register_script( 'my-script','/path/to/script' );
    wp_enqueue_script( 'my-script' );
}    

add_action( 'wp_enqueue_scripts', 'wpa_63708_enqueue_scripts' );
