Yii\validators\UrlValidator without http and https?

Question

Yii

How to forbid to enter the name of the protocol? Tried like this

['url', \yii\validators\UrlValidator::className(), 'validSchemes' => []],

But in this case, the options http://example.comand example.comboth are not valid.

Answer 1

Decided so

['url', \yii\validators\UrlValidator::className(), 'pattern' => '/^([a-z0-9\.-]{4,})$/i'],
