Source code

function locate_template($template_names, $load = false, $require_once = true ) {

	$located = '';

	foreach ( (array) $template_names as $template_name ) {

		if ( !$template_name )

			continue;

		if ( file_exists(STYLESHEETPATH . '/' . $template_name)) {

			$located = STYLESHEETPATH . '/' . $template_name;

			break;

		} else if ( file_exists(TEMPLATEPATH . '/' . $template_name) ) {

			$located = TEMPLATEPATH . '/' . $template_name;

			break;

		}

	}
