Property Details
An anonymous function or the name of a model class method that returns the client validation code. The signature of the method should be like the following:
function foo($attribute, $params)
{
return "javascript";
}
where $attribute refers to the attribute name to be validated.
Please refer to clientValidateAttribute() for details on how to return client validation code.
An anonymous function or the name of a model class method that will be
called to perform the actual validation. The signature of the method should be like the following,
where $attribute is the name of the attribute to be validated, and $params contains the value
of $params that you specify when declaring the inline validation rule:
function foo($attribute, $params)
Additional parameters that are passed to the validation method
Method Details
Returns the JavaScript needed for performing client-side validation.
You may override this method to return the JavaScript validation code if the validator can support client-side validation.
The following JavaScript variables are predefined and can be used in the validation code:
attribute: the name of the attribute being validated.value: the value being validated.messages: an array used to hold the validation error messages for the attribute.deferred: an array used to hold deferred objects for asynchronous validation
| string clientValidateAttribute( $model, $attribute, $view ) | ||
| $model | yii\base\Model | The data model being validated |
| $attribute | string | The name of the attribute to be validated. |
| $view | yii\web\View | The view object that is going to be used to render views or view files containing a model form with this validator applied. |
| return | string | The client-side validation script. Null if the validator does not support client-side validation. |
|---|---|---|
Validates a single attribute.
Child classes must implement this method to provide the actual validation logic.
| void validateAttribute( $model, $attribute ) | ||
| $model | yii\base\Model | The data model to be validated |
| $attribute | string | The name of the attribute to be validated. |
