最小数量验证器在Yii2模型中不起作用

Question

[['price'], 'integer', 'min' => 0, 'tooSmall' => 'Price cannot be less than 0'],

I have above rule in my model file. But while validating the model, return is true while passed NULL as price.

Any reason to this?

Answer 1

如果即使在字段为空的情况下也想进行验证，请将skipOnEmpty设置为false （默认情况下设置为true ）。

[['price'], 'integer', 'skipOnEmpty' => false, 'min' => 0, 'tooSmall' => 'Price cannot be less than 0'],
