How to accept integer data in yii2?

Question

Yii

Gentlemen, there is a form. The form submits lines, of course.
In one of the forms for deleting a user, a hidden input with id is submitted.
id must be an integer.
If I write in rules like this:

public function rules() {
        return [
        	['userid', 'required'],
        	['userid', 'integer', 'max' => 32, 'message' => 'Value should to be an integer'],
        ];
}

That validation does not work in principle, because userid is a string at POST
Are there any better validation methods than writing your own validation function, where the string is checked against a regular expression? Or in yii2 is it somehow possible to force the type to be converted before validation or to do something even more feng shui?

Answer 1

Actually, when checking, a string is parsed, so if you specify that the value should be an integer, then a pattern is checked: integerPattern .
So exactly what you want will come. Everything should be fine.

Answer 2

[['userid'], 'integer', 'max' => 32, 'message' => 'Value should to be an integer']

Answer 3

['userid','number']
