我可以設法將數據插入到tblaccount中。但問題是圖片無法上傳。 tblaccount包含名字，姓氏，電子郵件，部門，用戶名和密碼的正確數據，但即使我上傳了一些圖像，圖片仍保持空白。如何使用codeigniter上傳圖片？
更新：現在可以將圖片上傳到文件夾中，但tblaccount沒有運氣。它只顯示空白數據。
signup.php控制器：

$this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email|is_unique[tblaccount.Email]');
$this->form_validation->set_rules('department', 'Department', 'trim|required|alpha|min_length[3]|max_length[30]');
$this->form_validation->set_rules('username', 'Username', 'trim|required|alpha|min_length[3]|max_length[30]|is_unique[tblaccount.Username]');
$this->form_validation->set_rules('password', 'Password', 'trim|required');
$this->form_validation->set_rules('cpassword', 'Confirm Password', 'trim|required|matches[password]');

我現在可以上傳圖像的位置，也可以在tblaccount中的數據。我現在的問題是上傳按鈕可以上傳任何文件。如果它是空的，它的驗證是什麼？謝謝。 –
抱歉，對於遲到的回覆，因爲我已經在配置中檢查了允許的類型是jpg | jpeg | png | gif，所以只有這些文件纔會上傳，沒有其他的驗證，如果圖像上傳，如果它不是空的（$ _ FILES [圖片'] ['名稱']。你可以檢查通過jquery或其他條件給用戶的錯誤不是空的。 – aishwarya
