php - Wordpress - get meta data only from "published" articles -


i have dropdown meta data posts:

<form name="search" action="" method="get" class="form-dropdown">         <select name="city">         <option>stadt wählen</option>         <?php             $metakey = 'city';             $counties = $wpdb->query(                  $wpdb->prepare(                      "                     select distinct     meta_value                                    $wpdb->postmeta pm                     join                $wpdb->post p on pm.post_id = p.id                                   meta_key = %s                     ,                 post_status = 'published'                     order            meta_value asc                     ",                     $metakey                 )             );               if ($counties) {             foreach ($counties $city) {             echo "<option value=\"" . $city . "\">" . $city . "</option>";              }         }         ?>         </select>         <input type="submit" value="anzeigen" />     </form>

but 

and post_status = published

seems wrong here. idea how show meta data published posts? posts per rss feed plugin "feedwordpress" , puts old posts post status "retired" shown. no found no option in plugin put them trash instead ...

you missing single quotes in query, published string value , not column. ah, , @khushboo mentioned, post_status indeed column of posts table. have this:

$wpdb->query(      $wpdb->prepare(          "         select distinct     meta_value                        $wpdb->postmeta pm         join                $wpdb->post p on pm.post_id = p.id                       meta_key = %s         ,                 post_status = 'publish'         order            meta_value asc         ",         $metakey     ) );

but why don't use other query functions query_posts , query params?
