CodeIgniter - Call to a member function model() on a non-object
提问by mXX
I have a login form that is being created in the view. Then in my controller I'm trying to load my model but it doesn't seem to load. Looked up a few answer here on stackoverflow and almost everybody says autoload model, import the database library,etc. I did that but I'm still getting the error
我有一个正在视图中创建的登录表单。然后在我的控制器中，我试图加载我的模型，但它似乎没有加载。在stackoverflow上查了一些答案，几乎每个人都说自动加载模型，导入数据库库等。我这样做了，但我仍然收到错误

回答by SirCharles
You don't have a constructor, in your login controller:
您的登录控制器中没有构造函数：
public function __construct() {
parent::__construct();
}
回答by Karan Ashar
According to CodeIgniter docs
根据 CodeIgniter 文档
If you intend to use a constructor in any of your Controllers, you MUST place the following line of code in it: parent::__construct();
如果您打算在任何控制器中使用构造函数，则必须在其中放置以下代码行： parent::__construct();
Refer CI Constructorfor more.
