How to add more user identity session attributes in Yii2?

Question

In Yii2 you can access the identity interface for the current user by using the identityInterface object from within the \\yii\\web\\User class with something like this

Answer 1

You could also use a getter function to include additional identity information for the user. For example, retrieve fullname from a profile table.

class User extends ActiveRecord implements \yii\web\IdentityInterface
{
    // Other code goes here...       
    public function getFullname()
    {
        $profile = Profile::find()->where(['user_id'=>$this->id])->one();
        if ($profile !==null)
            return $profile->fullname;
        return false;
    }
}

Then, you can use it as if you have an attribute named fullname, like so

Yii::$app->user->identity->fullname;
