在wordpress元框上的多個圖像上傳

Question

我試圖創建8個字段上傳圖像，使用add_meta_box，但由於某種原因，不會上傳一些圖像（jpeg），無論其文件大小是否正確，寬度和高度也是正確的。

字段：

function facilitiesimage_box_render(){ 
    $status_message = get_post_meta($post->ID, 'facilities_img_error', true); 
      if($status_message) { 
       echo '<div class="error" id="message"><p>' . $status_message . '</p></div>'; 
      } 

      $max_no_img=8; // Maximum number of images value to be set here 


      echo '<input type="hidden" name="MAX_FILE_SIZE" value="1524288">'; 
      echo "<table border='0' width='400' cellspacing='0' cellpadding='0' align=center>"; 
      for($i=1; $i<=$max_no_img; $i++){ 
       echo "<tr><td>Images $i</td><td><input type=file name='images[]' class='bginput'></td></tr>"; 
      } 
      echo "<tr><td colspan=2 align=center><input type=submit value='Add Image'></td></tr>"; 
      echo "</form> </table>"; 
} 

的其餘代碼：

function update_facilitiesimage($post_id, $post) { 


     while(list($key,$value) = each($_FILES['images']['name'])) { 
      if(!empty($value)){ 
       $arr_file_type = wp_check_filetype(basename($value)); 
       $uploaded_file_type = $arr_file_type['type']; 
       $allowed_file_types = array('image/jpg', 'image/jpeg', 'image/gif', 'image/png'); 
       if(in_array($uploaded_file_type, $allowed_file_types)){ 
        $upload_dir = wp_upload_dir(); 
        $newname = strtolower(str_replace(' ', '-', $value)); 
        $add = $upload_dir['path'] . '/' . $newname; 
        copy($_FILES['images']['tmp_name'][$key], $add); 
        list($width, $height) = getimagesize($add); 
        $upload_image_width = '630'; 
        $upload_image_height = '350'; 
        if($width < $upload_image_width || $height < $upload_image_height) { 
         $upload_feedback = 'Sorry, the image ' . $value . ' does not meet the minimum height/width requirements. Please upload another image.<br/>'; 
         update_post_meta($post_id, 'facilities_img_error', $upload_feedback); 
         unlink($add); 
        } 
        else { 
         $upload_image_width = '630'; 
         $upload_image_height = '350'; 
         $resized = image_resize($add, $upload_image_width, $upload_image_height, true); 
         unlink($add); 
         $file_name_and_location = $add; 
         $file_title_for_media_library = 'your title here'; 
         $attachment = array(
          'post_mime_type' => $uploaded_file_type, 
          'post_title' => 'Uploaded image ' . addslashes($file_title_for_media_library), 
          'post_content' => '', 
          'post_status' => 'inherit' 
         ); 
         $attach_id = wp_insert_attachment($attachment, $file_name_and_location); 
         require_once(ABSPATH . "wp-admin" . '/includes/image.php'); 
         $attach_data = wp_generate_attachment_metadata($attach_id, $file_name_and_location); 
         wp_update_attachment_metadata($attach_id, $attach_data); 
         $ra = 'attached_facility-img' . $key; 
         $existing_uploaded_image = (int) get_post_meta($post_id, $ra, true); 
         if(is_numeric($existing_uploaded_image)) { 
          wp_delete_attachment($existing_uploaded_image); 
         } 
         update_post_meta($post_id, $ra ,$attach_id); 
         $upload_feedback = false; 
         update_post_meta($post_id, 'facilities_img_error', $upload_feedback); 
         $fname = strrchr($resized, '/'); 
         $img = $upload_dir['baseurl'] . $fname; 
         $table = 'facilitiesimage-' . $key; 
         delete_post_meta($post_id, $table); 
         update_post_meta($post_id, $table, $img); 
        } 
       } 
       else { 
        $upload_feedback = 'Please upload only image files (jpg, gif or png).<br/>'; 
        update_post_meta($post_id, 'facilities_img_error', $upload_feedback); 
       } 
      } 
     } 
    } 

add_action('save_post','update_facilitiesimage',1,2); 

手之前我只是在學習，所以我對任何大錯（或恐怖）在道歉我的代碼。

所有這一切工作正常，直到我有一些圖像不會更新，這些圖像是JPEG格式，文件大小和尺寸是代碼中的值。

使用：

echo "<pre>"; 
echo "POST:"; 
print_r($_POST); 
echo "FILES:"; 
print_r($_FILES); 
echo "</pre>"; 

我發現的值是否正確（圖像通過「驗證」），但圖像沒有得到上傳。請注意，該腳本沒有上傳其他JPEG圖像的問題。

任何幫助將不勝感激提前
