How can I create a constructor in a Yii2 model

Question

How can I create a constructor in a Yii2 model? because i want to convert a CI model to Yii2 model.

I would appreciate a working example.

Answer 1

From the official documentation:

It is recommended that you perform object initialization in the init() method because at that stage, the object configuration is already applied. http://www.yiiframework.com/doc-2.0/yii-base-baseobject.html

So it depends a bit on what exactly you want to do in your constructor. For most cases, this would be the standard approach:

public function init()
{
    parent::init();

    // ... initialization after configuration is applied
}

Answer 2

Create this function in your model class:

function __construct()
{
    parent::__construct();
    ...
}
