You may also override yii\validators\Validator::validate Value() instead of ) when attaching validator.

This is because the same validator will run for each attribute (3 times in total) and we only need to run it once for the whole attribute set.

This should be done by overriding the yii\base\Model::rules() method.

The following example shows how the validation rules for the Most validators have default error messages that will be added to the model being validated when its attributes fail the validation.

In this case we can use yii\validators\Validator::add Error() to set customized message for the model.

A complete processing of user input is shown in the following example code, which will ensure only integer values are stored in an attribute: for values that are not bound to any model.the validation of one attribute depends on the value of another attribute you can use the when property to define such conditions. The following examples shows how to trim the spaces in the inputs and turn empty inputs into nulls by using the trim and default core validators: You may also use the more general filter validator to perform more complex data filtering.For example, If you also need to support client-side conditional validation, you should configure the when Client property which takes a string representing a Java Script function whose return value determines whether to apply the rule or not. As you can see, these validation rules do not really validate the inputs.You may also access the dynamic attributes defined through the model instance, e.g., .Besides using the core validators included in the Yii releases, you may also create your own validators.
