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

任何一个可以给我一个解决这个错误的解决方案。我尝试使用管理员用户名和密码登录，但它告诉我这一点，更像是一串误差转换

Answer 1

有typo双$this

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

更改为

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

注：而且same mistake在很多other lines也太在意了。

Answer 2

它应该是$这个 - >输入 - >后（“密码”）

Answer 3

你有键入错误是$这个 - > $这在3个地方在你的代码。
