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, $validator)
{
return "javascript";
}
where $attribute refers to the attribute name to be validated.
Please refer to clientValidateAttribute() for details on how to return client validation code.
The value of attribute being currently validated.
An anonymous function or the name of a model class method that will be called to perform the actual validation. The signature of the method should be like the following:
function foo($attribute, $params, $validator)
$attributeis the name of the attribute to be validated;$paramscontains the value of $params that you specify when declaring the inline validation rule;$validatoris a reference to related yii\validators\InlineValidator object. This parameter is available since version 2.0.11.
Additional parameters that are passed to the validation method
Method Details
Returns the JavaScript needed for performing client-side validation.
Calls getClientOptions() to generate options array for 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: an object describing the 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$form: a jQuery object containing the form element
The attribute object contains the following properties:
id: a unique ID identifying the attribute (e.g. "loginform-username") in the formname: attribute name or expression (e.g. "[0]content" for tabular input)container: the jQuery selector of the container of the input fieldinput: the jQuery selector of the input field under the context of the formerror: the jQuery selector of the error tag under the context of the containerstatus: status of the input field, 0: empty, not entered before, 1: validated, 2: pending validation, 3: validating
| public string|null 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|null | 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.
| public void validateAttribute ( $model, $attribute ) | ||
| $model | yii\base\Model | The data model to be validated |
| $attribute | string | The name of the attribute to be validated. |
