Allow supressing the hook in wp_print_(script|style)()

[scribu]

Here's an example of what I'm currently doing:

class My_Shortcode {
	static $add_script;
 
	function init() {
		add_shortcode('myshortcode', array(__CLASS__, 'handle_shortcode'));
		add_action('wp_footer', array(__CLASS__, 'add_script'));
	}
 
	function handle_shortcode($atts) {
		self::$add_script = true;
 
		// actual shortcode handling here
	}
 
	function add_script() {
		global $wp_scripts;
 
		if ( ! self::$add_script )
			return;
 
		wp_register_script('my-script', plugins_url('my-script.js', __FILE__), array('jquery'), '1.0', true);
 
		$wp_scripts->do_items('my-script');
	}
}
 
My_Shortcode::init();

From ​here.

It would be nice to replace

$wp_scripts->do_items('my-script');

with

wp_print_scripts('my-script');

The problem is that wp_print_scripts() fires the 'wp_print_scripts' hook, which can cause problems, like duplicate JavaScript code, etc.

All that's needed is a way to suppress that hook, when needed.

second argument for wp_print_scripts() and wp_print_styles()

won't this prevent depends from being fetched?

I use the method in one of my plugins and it works great.

I would just like to not have to call $wp_scripts myself.

Also, the patch is 100% backwards-compatible with everything. :)

Just to clarify, the duplicate javascript code would be the result of the queue getting flushed and then potentially filled again with the same scripts, right (as far as I remember, the queue is emptied when it's printed)?

Wouldn't the ideal solution be to call a wp_print_scripts() again in the footer to flush out everything queued up for it? This way you don't have to manually call wp_print_scripts().

Replying to archon810:

Actually, no. You can call wp_print_scripts() as many times as you want, and you won't get duplicate scripts.

I was thinking of plugins doing other stuff, like manually outputing <script> tags, but that would be foolish.

So I guess there's nothing to worry about.

Yes, that would be the ideal solution. I'll open a new ticket for that.
