在我的主题中，我为用户提供了一个选项，可以设置一个“博客类别”，在index.php 使用WP_Query:

$shortname = get_option(\'of_shortname\');
$cat_option = get_option($shortname.\'_cats_in_blog\');
$catid = get_cat_ID($cat_option);
$paged = get_query_var( \'paged\' ) ? get_query_var( \'paged\' ) : 1;
$args = array(
   \'cat\' => $catid,
   \'paged\' => $paged
);

$query = new WP_Query( $args );

// Queries fine, but search stops working       
while ( $query->have_posts() ) : $query->the_post();

// Loop stuff here

endwhile;

这很好，但搜索小部件坏了。我还尝试使用query_posts 但这有相反的效果；查询的类别未显示，但搜索仍起作用。下面是代码：

$shortname = get_option(\'of_shortname\');
$cat_option = get_option($shortname.\'_cats_in_blog\');
$catid = get_cat_ID($cat_option);

// Search is working, querying is not
global $query_string; // required
$posts = query_posts($query_string.\'&posts_per_page=3&cat=$catid\');

while ( $query->have_posts() ) : $query->the_post();

// Loop stuff here

endwhile;

我检查了$catid 变量，它将返回应该返回的内容。我是以错误的方式还是在错误的地方提出质疑？非常感谢您的帮助，提前感谢。

// Search is working, querying is not
global $query_string; // required
$posts = query_posts($query_string.\'&posts_per_page=3&cat=$catid\');

while ( $query->have_posts() ) : $query->the_post();

// Search is working, querying is not
global $query_string; // required
$posts = query_posts($query_string.\'&posts_per_page=3&cat=$catid\');

while ( have_posts() ) : the_post();

$posts = query_posts($query_string.\'&posts_per_page=3&cat=$catid\');

$posts = query_posts( $query_string . \'&posts_per_page=3&cat=\' . $catid );
