在 WordPress 中的查询帖子中传递数组值

Question

我的 WordPress 代码如下：

Array ( [0] => 393 [1] => 362 [2] => 361 )

我想将此数组转换为

array(393,362,361)

并且我想将此数组传递到 WordPress 的查询帖子中。

$getphotoidfromurl = 5;
global $wpdb;
// $sqlselque = "SELECT post_id FROM wp_postmeta WHERE meta_key = 'metrodir_company_gallery' LIMIT 0 , 30";
    
$db_item = $wpdb->get_results($wpdb->prepare("SELECT post_id,meta_value FROM wp_postmeta WHERE meta_key = 'metrodir_company_gallery' LIMIT 0 , 30"));
$r1 = array();
foreach ($db_item as $rs) {
    // echo $rs->post_id;
    $getphotos = $rs->meta_value;
    $rr = explode(",", $getphotos);
    $getphotocount = count($rr);
    
    if ($getphotoidfromurl == $getphotocount) {
        $newgettwo = $rs->post_id;
        // print_r($array);
        array_push($r1, $newgettwo);
    }
}
print_r($r1);
exit;
global $wp_query;
    
query_posts(array(
    'post_type' => array('company'),
    'posts_per_page' => -1,
    'orderby' => $orderby,
    'order' => $order,
));

我的 WordPress 查询应如下所示：

query_posts(array(
    'post_type' => array('company'),
    'posts_per_page' => -1,
    'orderby' => $orderby,
    'order' => $order,
    'p'  => array(393,362,361)
));

只需简单地输入 $r1，因为当我们 print_r($r1); 时，你的结果 $r1 就可以了； 它向我们显示数组键索引

         query_posts(array(
                    'post_type' => array('company'),
                    'posts_per_page' => -1,
                    'orderby' => $orderby,
                    'order' => $order,
                    'p'  => $r1  //see here 

例如

$r1=array(393,362,361);
print_r($r1);
    //result        
     Array ( [0] => 393 [1] => 362 [2] => 361 )
