我一直在使用本教程，该教程将分类法过滤器添加到存档中。php和它的工作原理，但输出是一个新的WP查询，与帖子标题相呼应。如何修改函数以使其应用于主查询，而不是创建新查询？是否有此过滤器？我知道pre\\u get\\u帖子，但由于它使用ajax，我不知道如何将其组合在一起。

Html form on archive.php

            echo \'<select name="genrefilter"><option value="">Select category...</option>\';
            foreach ( $terms as $term ) :
                echo \'<option value="\' . $term->term_id . \'">\' . $term->name . \'</option>\'; // ID of the category as the value of an option
            endforeach;
            echo \'</select>\';
        endif;
    ?>
