Setting up regular expression validation in Yii2?

Question

Yii

I get an error: Getting unknown property: frontend\models\Product::match

[['title',  'match', 'pattern' => '/^[а-яА-Я1-9\s]/i'], 'string', 'max' => 255],

Answer 1

Good evening.
So it will be more correct, remove everything else:

['title',  'match', 'pattern' => '/^[а-яА-Я1-9\s]/i']
