イメージサイズ変更php prestashop

Question

私はprestashopでアップロード時に画像のサイズを変更しようとしましたが、うまく動作しません。 HERE

$images = count($_FILES['specialImg']['name']); 
     $minwidth = 1500; 
     $minheight = 1500; 
     if ($images <= Configuration::get('JMARKETPLACE_MAX_IMAGES')) { 
      for ($i=1; $i<=Configuration::get('JMARKETPLACE_MAX_IMAGES'); $i++) { 
       if ($_FILES['specialImg']['name'][$i] != "") { 
        if ((($_FILES['specialImg']['type'][$i] == "image/pjpeg") || 
         ($_FILES['specialImg']['type'][$i] == "image/jpeg") || 
         ($_FILES['specialImg']['type'][$i] == "image/png")) && 
         ($_FILES['specialImg']['size'][$i] < $this->return_bytes(ini_get('post_max_size')))) { 

         list($width, $height, $type, $attr) = getimagesize($_FILES['specialImg']['tmp_name'][$i]);  
//HERE IS MY RESIZE       
ImageManager::resize($_FILES['specialImg']['tmp_name'][$i], 200, 200); 

if ($width == $minwidth && $height == $minheight) { 
         $url_images[$i] = $_FILES['specialImg']['tmp_name'][$i]; 
        } 

は、関数のサイズを変更PrestaShopの、しかし、私は、ファイルがアップロードされていないが、サイズ変更され、エラーはそれを動作させるカントがありますか？！誰かがどのようにそれは私のスクリプトで完璧WORXこの機能で
