Call to a member function get() on null error
提问by Veronica
I keep getting this error in CodeIgniter-2.2.1.(Fatal error: Call to a member function get() on null in C:\xampp\htdocs\ci\application\models\site_model.php on line 6) I am not sure why this is happening. Am I calling the function correctly? Line 6 is $this->load->model('site_model');
我在 CodeIgniter-2.2.1 中不断收到此错误。（致命错误：在第 6 行 C:\xampp\htdocs\ci\application\models\site_model.php 中调用成员函数 get() on null）我不是确定为什么会发生这种情况。我是否正确调用了该函数？第 6 行是 $this->load->model('site_model');
