我有一个付费主题，它有以下手动硬编码的功能。它将调出8条最新帖子并显示它们：

global $do_not_duplicate;
global $post;

query_posts( array(
    \'posts_per_page\'        => \'8\',
    \'post__not_in\'          => $do_not_duplicate,
    \'ignore_sticky_posts\'   => 1
) );

我已经看过了this page 并试图修改代码以仅显示新闻类别中的帖子（类别编号1）：

global $do_not_duplicate;
global $post;

// Attempt 1
query_posts( array(
    \'cat=1\',
    \'posts_per_page\' => \'8\',
    \'post__not_in\' => $do_not_duplicate,
    \'ignore_sticky_posts\' => 1
) );

// Attempt 2
query_posts( array(
    \'category=1\',
    \'posts_per_page\' => \'8\',
    \'post__not_in\' => $do_not_duplicate,
    \'ignore_sticky_posts\' => 1
) );

// Attempt 3
query_posts( array(
    \'category\' => array(1),
    \'posts_per_page\' => \'8\',
    \'post__not_in\' => $do_not_duplicate,
    \'ignore_sticky_posts\' => 1
) );

// Attempt 4
query_posts( array(
    \'cat=news\',
    \'posts_per_page\' => \'8\',
    \'post__not_in\' => $do_not_duplicate,
    \'ignore_sticky_posts\' => 1
) );

什么都没用。返回了所有职类最近8个员额的同一名单。

query_posts( array(
    \'cat\' => 1,
    \'posts_per_page\' => \'8\',
    \'post__not_in\' => $do_not_duplicate,
    \'ignore_sticky_posts\' => 1
) );
