Question

下面的代码在wordpress中产生以下输出-Array（[0] =＆gt; 393 [1] =＆gt; 362 [2] =＆gt; 361）。

我想将此数组（[0] =＆gt; 393 [1] =＆gt; 362 [2] =＆gt; 361）转换为数组（393,362,361），我想传递此信息数组到wordpress查询帖子。

  <?php
                $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 "hello";
//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,


                ));

所以我的wordpress查询应该是这样的 -

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，你得到的$ r1就可以了。它向我们展示了数组密钥索引

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

e.g

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

在wordpress中的查询帖子中传递数组值
