[wp-hackers] wp_enqueue_script() and URLs with 2+ parameters

[Glenn Ansley]

>> My current project needs this on tens of pages; for example I have a script that is specific to the video gallery page and is doen't need to be and probably shouldn't be included elsewhere.

function testers(){
	global $wp_query;
	if ( 4 == $wp_query->query_vars['page_id'] ) :
		echo "Ta da!";
	endif;
}
add_action('template_redirect','testers');

// assuming 4 is the page you're looking for... or you could do
in_array() for mulitple pages, or use the p variable, etc

One small thing that would be less-than-idal is that doing this would duplicate some significant logic in core such as the logic found in template-loader.php.  It would be nice if the code in lines 17-59 were refactored into a function that returned the template file name so that logic could be used elsewhere. Would this be the type of thing appropriate to add a ticket into track for?
