Scherzo child themes won't register functions.php scripts

Hi there,

I’ve created a theme called Scherzo.

I’m planning to release a new version but one thing is holding me up.

I’ve created a responsive design that targets desktop browsers with @media CSS queries. As IE doesn’t understand @media queries I use some javascript to get IE to do my bidding.

The js is stored in a folder entitled js in the theme folder. It works just fine with the Scherzo theme but, for some reason, child themes don’t seem to load it.

This is how I register and enqueue the js in Scherzo’s functions.php:

if ( !function_exists( 'scherzo_scripts' ) ) :

	function scherzo_scripts() {

	    if (!is_admin()) {

		wp_register_script( 'html5shiv', get_template_directory_uri() . '/js/html5.js');
		wp_register_script( 'css3mediaqueries', get_template_directory_uri() . '/js/css3-mediaqueries.js');
		wp_enqueue_script('html5shiv');
		wp_enqueue_script('css3mediaqueries');

	    }
	}

	add_action('init', 'scherzo_scripts');

endif;

My understanding of child themes is that they simply inherit the parent theme’s functions.php functions. But this doesn’t seem to be the case. For examples, see:

A site running Scherzo
A site running a child theme of Scherzo (the only change is the link colours — no layout changes or anything else).

If you load both sites in IE you’ll see the child theme isn’t obeying @media queries — it’s just using the one column CSS.

TIA,

Leon
