How in Yii2 to specify models at login a choice from two fields?

Question

Yii

Hello. How to login using either username or email in Yii2?
So far, the idea is only with "range"

Answer 1

Try in LoginForm, in getUser search either by login or by email.
Set the validation rules accordingly so that you don’t swear at the absence of one of the parameters, for the login, if instead of the login email and for email, if the login is specified instead of email.

Answer 2

In the findByUsername method, add a search by the email field.

public static function findByUsername($username)
    {
        return static::find()->where(['username' => $username])->orWhere(['email' => $username])->one();
    }
