| Implements | yii\base\Configurable |
| Available since version | 2.0 |
| Source Code | https://github.com/yiisoft/yii2/blob/master/framework/validators/UrlValidator.php |
UrlValidator validates that the attribute value is a valid http or https URL.
Note that this validator only checks if the URL scheme and host part are correct. It does not check the remaining parts of a URL.

| validateValue() | Validates a value. | yii\validators\UrlValidator |
The default URI scheme. If the input doesn't contain the scheme part, the default scheme will be prepended to it (thus changing the input). Defaults to null, meaning a URL must contain the scheme part.
public string $defaultScheme = null
Whether validation process should take into account IDN (internationalized domain names). Defaults to false meaning that validation of URLs containing IDN will always fail. Note that in order to use IDN validation you have to install and enable intl PHP extension, otherwise an exception would be thrown.
public boolean $enableIDN = false
The regular expression used to validate the attribute value. The pattern may contain a {schemes} token that will be replaced by a regular expression which represents the $validSchemes.
public string $pattern = '/^{schemes}:\/\/(([A-Z0-9][A-Z0-9_-]*)(\.[A-Z0-9][A-Z0-9_-]*)+)(?::\d{1,5})?(?:$|[?\/#])/i'
List of URI schemes which should be considered valid. By default, http and https are considered to be valid schemes.
public array $validSchemes = ['http', 'https']
Returns the JavaScript needed for performing client-side validation.
Calls getClientOptions() to generate options array for client-side validation.
You may override this method to return the JavaScript validation code if the validator can support client-side validation.
The following JavaScript variables are predefined and can be used in the validation code:
attribute: an object describing the the attribute being validated.value: the value being validated.messages: an array used to hold the validation error messages for the attribute.deferred: an array used to hold deferred objects for asynchronous validation$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 |
if the validator does not supporting data validation without a model |
