| Available since version | 2.0 |
| Source Code | https://github.com/yiisoft/yii2/blob/master/framework/validators/RangeValidator.php |
RangeValidator validates that the attribute value is among a list of values.
The range can be specified via the $range property. If the $not property is set true, the validator will ensure the attribute value is NOT among the specified range.

Whether to allow array type attribute.
public boolean $allowArray = false
Whether to invert the validation logic. Defaults to false. If set to true, the attribute value should NOT be among the list of values defined via $range.
public boolean $not = false
A list of valid values that the attribute value should be among or an anonymous function that returns such a list. The signature of the anonymous function should be as follows,
function($model, $attribute) {
// compute range
return $range;
}
public array|Traversable|Closure $range = null
Whether the comparison is strict (both type and value must be the same)
public boolean $strict = false
Returns the JavaScript needed for performing client-side validation.
Calls getClientOptions() to generate options array for client-side validation.
You may override this method to return the JavaScript validation code if the validator can support client-side validation.
The following JavaScript variables are predefined and can be used in the validation code:
attribute: an object describing the the attribute being validated.value: the value being validated.messages: an array used to hold the validation error messages for the attribute.deferred: an array used to hold deferred objects for asynchronous validation$form: a jQuery object containing the form elementThe 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. |
Returns the client-side validation options.
This method is usually called from clientValidateAttribute(). You may override this method to modify options that will be passed to the client-side validation.
| public array getClientOptions ( $model, $attribute ) | ||
|---|---|---|
| $model | yii\base\Model |
The model being validated |
| $attribute | string |
The attribute name being validated |
| return | array |
The client-side validation options |
Initializes the object.
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
| public void init ( ) |
|---|
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. |
Validates a value.
A validator class can implement this method to support data validation out of the context of a data model.
| protected array|null validateValue ( $value ) | ||
|---|---|---|
| $value | mixed |
The data value to be validated. |
| return | array|null |
The error message and the parameters to be inserted into the error message. Null should be returned if the data is valid. |
| throws | yii\base\NotSupportedException |
