while loop stile wordpress

[diaz]

grazie Filippo

Invio il codice per chi fosse interessato o se qualcuno ha consigli su come migliorarlo

        <?php while (gallery_get_previews('random', 6)) : ?>
          <div>
            [url="<?php gallery_image_link() ?>"][img]<?php gallery_image_url('thumb'); ?>[/img][/url]
            <?php gallery_image_title(); ?>
          </div>
        <?php endwhile; ?>

la funzione

function gallery_get_previews($method, $quantity)
{
  
  // the following variable is the resource of the query, it must be unique to this function
  global $gallery_get_previews_result;
  
  global $conn, $row;
  
  // prepare query statement
  $sql = "SELECT * FROM images";
  $sql .= " ORDER BY id_image ASC ";
  if($quantity) $sql .= " LIMIT ".$quantity;
  
  if(!$gallery_get_previews_result)
  {
    $gallery_get_previews_result = mysql_query($sql, $conn);
  }
  
  $row = mysql_fetch_object($gallery_get_previews_result);
  
  return $row;
  
  // free the result
  mysql_free_result($gallery_get_previews_result);
}
