無法使用Codeigniter將上傳的圖像路徑存儲在數據庫中

Question

我在google上讀過類似的查詢，在那兒我讀到有關檢查文件是否可寫，然后使用chmod（）函數設置權限的信息，但是我也嘗試過，但沒有成功。 我想將圖像路徑存儲在數據庫中，然后將圖像移至上載文件夾。 圖像的路徑將為：C：/xampp/htdocs/konnect1/uploads/Hydrangeas1.jpg使用chmod（）時，出現警告消息為“消息：chmod（）：無此類文件或目錄”。 請幫忙，因為我現在應該更改什么。

控制器頁面-> admin_c.php發布函數，在其中寫入圖像上傳代碼。

          public function create_event1()

            $c = $count;
            //echo $c;

Answer 1

根據錯誤消息，似乎PHP無法找到目錄。

請首先使用PHP函數is_dir（）首先驗證PHP是否可以將該路徑識別為文件夾。

一旦返回true，就可以繼續使用它。

同樣在您的上傳路徑中，您以/開頭，這意味着您的項目位於OS的根目錄中，我認為該位置不正確。

從終端cd到項目目錄，然后運行命令pwd並獲取當前的工作目錄，然后在考慮項目位置后使用正確的上載路徑。
