我应该如何编辑以下代码,以便只回显其中的2篇帖子,而不是3篇
<?php
global $more; $more = false; # some wordpress wtf logic
$num_of_posts = $wp_query->post_count;
$current = -1;
$cat_id = get_cat_ID(single_cat_title(\'\', false));
if(!empty($cat_id))
{
$query_string.= \'&cat=\'.$cat_id;
}
query_posts($query_string);
if (have_posts()) : while (have_posts()) : the_post(); $current++
?>
<?php if($current == 0) { ?>
