To add a search form that searches only a particular post type, not your entire website.
<form id="cptsearch" action="<?php echo home_url(); ?>" method="get"><input name="s" type="text" /> <input name="post_type" type="hidden" value="POSTTYPENAME" /> <input id="searchsubmit" alt="Search" type="submit" value="Search" /> </form>
Want results to use a different template than the normal search results? Add to functions.php:
function template_chooser($template) { global $wp_query; $post_type = get_query_var('post_type'); if( $wp_query->is_search && $post_type == 'POSTTYPENAME' ) { return locate_template('page_POSTTYPENAME.php'); } return $template; } add_filter('template_include', 'template_chooser');
