不刪除保存數據。如果，我在Opencart 3中卸載模塊

Question

我已經更新了我的主題模塊OpenCart 3.0.2.0。通常這工作正常。但是，確實會造成一個小問題。

如果我從admin（擴展>擴展>模塊）中卸載了我的自定義主題模塊。雖然，不會從前端&管理端刪除保存的數據。 的時候，我會再次安裝&編輯模塊。所以，不要刪除上面保存的數據。另外，保存的數據設置不會從前面刪除。它仍然保存數據。

這在舊的（2.3.0.2）版本中工作正常。但是，在這裏，我無法判斷。爲什麼這發生在最新版本。 你可以請任何建議嗎？以下代碼我們的文件。

mytheme.php（管理員\控制器\推廣\模塊）

你可以在你的控制器創建卸載功能。

public function uninstall() { 
     $this->load->model('setting/setting'); 
     $this->model_setting_setting->deleteSetting('mytheme'); 

} 

您不需要調用此函數。卸載模塊時會自動調用。

祝你好運。 :)
