WP_QUERY不使用变量

如果我使用此代码（代码不完整，这是问题部分），帖子会正确显示。注意“新的WP\\U查询（\'cat=2,3,5,6,7,8,9”）；”：

$catslugs = array(\'academic\',/*\'adventure\',*/ \'arts\', \'religious\', \'special-interest\', \'special-needs\', \'sports\',\'teen\');//Must upate as new Main categories are added 
    $out = array();
    foreach($catslugs as $slug) {
        array_push($out, get_category_by_slug($slug)->term_id);
        $CatIDs= implode(\',\', $out);
        }
    //featured category ID = 153
    //academic category ID = 2
    //adventure category ID = 4
    //arts category ID = 3
    //religious category ID = 5
    //special-interest category ID = 6
    //special-needs category ID = 7
    //sports category ID = 8
    //teen category ID = 9
    $CatIDsCode="\'cat=".$CatIDs."\'";
    $camp_posts_bynumber = new WP_Query(\'cat=2,3,5,6,7,8,9\');

    if( $camp_posts_bynumber->have_posts() ):

如果我把它改成这个，它不会。相反，它会显示所有类别，包括“未分类”。我做错了什么？是不是写着“have\\u posts（）”的东西

$catslugs = array(\'academic\',/*\'adventure\',*/ \'arts\', \'religious\', \'special-interest\', \'special-needs\', \'sports\',\'teen\');//Must upate as new Main categories are added 
$out = array();
foreach($catslugs as $slug) {
    array_push($out, get_category_by_slug($slug)->term_id);
    $CatIDs= implode(\',\', $out);
    }
//featured category ID = 153
//academic category ID = 2
//adventure category ID = 4
//arts category ID = 3
//religious category ID = 5
//special-interest category ID = 6
//special-needs category ID = 7
//sports category ID = 8
//teen category ID = 9
$CatIDsCode="\'cat=".$CatIDs."\'";
$camp_posts_bynumber = new WP_Query($CatIDsCode);

if( $camp_posts_bynumber->have_posts() ):

或

$catslugs = array(\'academic\',/*\'adventure\',*/ \'arts\', \'religious\', \'special-interest\', \'special-needs\', \'sports\',\'teen\');//Must upate as new Main categories are added 
$out = array();
foreach($catslugs as $slug) {
    array_push($out, get_category_by_slug($slug)->term_id);
    $CatIDs= implode(\',\', $out);
    }
//featured category ID = 153
//academic category ID = 2
//adventure category ID = 4
//arts category ID = 3
//religious category ID = 5
//special-interest category ID = 6
//special-needs category ID = 7
//sports category ID = 8
//teen category ID = 9
$CatIDsCode="\'cat=".$CatIDs."\'";
$camp_posts_bynumber = new WP_Query($CatIDs);

if( $camp_posts_bynumber->have_posts() ):

使用新的WP-Query()从循环中过滤后期格式；

嗨，我目前正在为我的博客构建一个主题。下面的代码指向最新的帖子（特色帖子）。因为这将有一个不同的风格比所有其他职位。然而我想过滤掉帖子格式：链接使用我在循环中定义的WP查询，因为它给我带来了更多的灵活性。我该怎么做呢？ <?php $featured = new WP_Query(); $featured->query(\'showposts=1\'); ?> <?php while ($featured->have_post
