public function login() { 
    //check user type 

    $this->_table_name = 'tbl_employee_login'; 
    $this->_order_by = 'employee_login_id'; 
    $employee = $this->get_by(array(
     'email' => $this->input->post('email'), 
     'password' => $this->$this->input->post('password'), LINE NUMBER 27 
     'activate' => 1 
    ), TRUE); 
    /*employee*/ 
    $this->_table_name = 'driver';

      'url' => 'driver/dashboard', 
     ); 
     $this->session->set_userdata($data); 
    } 
} 

任何一個可以給我一個解決這個錯誤的解決方案。我嘗試使用管理員用戶名和密碼登錄，但它告訴我這一點，更像是一串誤差轉換

Answer 1

有typo雙$this

'password' => $this->$this->input->post('password'), 

更改爲

'password' =>$this->input->post('password'), 

注：而且same mistake在很多other lines也太在意了。

Answer 2

它應該是$這個 - >輸入 - >後（「密碼」）

Answer 3

你有鍵入錯誤是$這個 - > $這在3個地方在你的代碼。
