Opencart：錯誤號：1062鍵'PRIMARY'的重複項'1'

我正在開發具有項目ID，項目名稱，鏈接，圖像，排序順序的opencart的輪播擴展。轉盤有一個問題，同時保存它會改變項目ID，所以我不得不修改代碼以獲取固定ID查詢到數據庫，但是現在我得到了1062錯誤。Opencart：錯誤號：1062鍵'PRIMARY'的重複項'1'

Notice: Error: Duplicate entry '1' for key 'PRIMARY' Error No: 1062 INSERT INTO crousal SET crousal_id = '1', name = 'Baby & Toys', link = '/index.php?route=product/product&product_id=7570', image = 'data/carousel/banner2.jpg', sort_order = '0' in /home/user/public_html/system/database/mysql.php on line 49

共享模型/ carousel.php editCarousel功能

public function editCrousal($crousal_image) { 

    $crousal_id = $this->db->getLastId(); 

    $this->db->query("DELETE FROM " . DB_PREFIX . "mobiapp_crousal WHERE crousal_id = '" . (int)$crousal_id . "'"); 

    if (isset($crousal_image['crousal_image'])) { 
     foreach ($crousal_image['crousal_image'] as $crousal_image) { 

      $this->db->query("INSERT INTO " . DB_PREFIX . "mobiapp_crousal SET crousal_id = '" . (int)$crousal_id . "', name = '" . $this->db->escape($crousal_image['name']) .

      $crousal_id = $this->db->getLastId(); 

     } 
    } 
}

任何意見，爲什麼我收到此錯誤以及如何解決，謝謝你在先進。

P.S：Opencart的1.5.x的

看起來像模塊不清楚。請提供有關模塊和數據庫表結構的更多信息 –

我編輯了問題並添加了有關模塊和數據庫結構的更多信息 –

我沒有審查該模塊。看起來像這個模塊有完全錯誤的結構。正如您在方法addCrousal foreach-statement中看到的那樣插入數據庫。但是在這個插入carousal_id不會遞增，所以在表中將會記錄不是唯一的carousal_id。所以這個專欄不能是主要的。我建議你用關係（有很多）「圖像」兩個表格「幻燈片」重寫模塊。或者你可以刪除PRIMARY索引，操作會通過，但這不是真正的解決方案。

如果我理解您所說的話，您指的是創建數據庫並在它們之間存在關係我們添加classify旋轉木馬項目查詢。我想提一下，我已經複製了默認的Opencart Banner mod並對其進行了修改，並且Carousel是一個列表，而不是多列表，因爲它帶有Opencart> Banners –

ya。但是，嘿。爲什麼不使用默認模塊Carousel而不是橫幅？ –

因爲我正在爲移動應用程序創建一個API，它將使用它自己的數據庫和工作流 –
