如果您可以使用template_redirect 钩子和一个简单的函数来设置要使用的模板

add_action( \'template_redirect\', \'category_set_redirect\' );
function category_set_redirect(){
    //create the sets of categories
    $first_set= array("1","2","3","4","5","6");
    $second_set= array("7","8","9","10","11","12");

    if (is_category()){
        if (in_array(get_query_var(\'cat\'),$first_set)){
            include(TEMPLATEPATH . "/first_category.php"); // include the corresponding template
            die();
        }
        if (in_array(get_query_var(\'cat\'),$second_set)){
            include(TEMPLATEPATH . "/second_category.php"); // include the corresponding template
            die();
        }   
    }
}
