GroupUrlRule represents a collection of URL rules sharing the same prefix in their patterns and routes.

GroupUrlRule is best used by a module which often uses module ID as the prefix for the URL rules. For example, the following code creates a rule for the admin module:

new GroupUrlRule([
    'prefix' => 'admin',
    'rules' => [
        'login' => 'user/login',
        'logout' => 'user/logout',
        'dashboard' => 'default/dashboard',
    ],
]);

// the above rule is equivalent to the following three rules:

[
    'admin/login' => 'admin/user/login',
    'admin/logout' => 'admin/user/logout',
    'admin/dashboard' => 'admin/default/dashboard',
]

The above example assumes the prefix for patterns and routes are the same. They can be made different by configuring $prefix and $routePrefix separately.

Using a GroupUrlRule is more efficient than directly declaring the individual rules it contains. This is because GroupUrlRule can quickly determine if it should process a URL parsing or creation request by simply checking if the prefix matches.

Property Details

Hide inherited properties

$prefix public property

The prefix for the pattern part of every rule declared in $rules. The prefix and the pattern will be separated with a slash.

public string $prefix = null
$routePrefix public property

The prefix for the route part of every rule declared in $rules. The prefix and the route will be separated with a slash. If this property is not set, it will take the value of $prefix.

public string|null $routePrefix = null
$ruleConfig public property

The default configuration of URL rules. Individual rule configurations specified via $rules will take precedence when the same property of the rule is configured.

public array $ruleConfig = [
    'class' => 'yii\web\UrlRule',
]
$rules public property

The rules contained within this composite rule. Please refer to yii\web\UrlManager::$rules for the format of this property.

public array $rules = []

Method Details

__call() public method

Defined in: yii\base\BaseObject::__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

public mixed __call ( $name, $params )
$name string

The method name
$params array

Method parameters
return mixed

The method return value
throws yii\base\UnknownMethodException

when calling unknown method

 

                public function __call($name, $params)
{
    throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
__construct() public method

Defined in: yii\base\BaseObject::__construct()

Constructor.

The default implementation does two things:

  • Initializes the object with the given configuration $config.
  • Call init().

If this method is overridden in a child class, it is recommended that

  • the last parameter of the constructor is a configuration array, like $config here.
  • call the parent implementation at the end of the constructor.
public void __construct ( $config = [] )
$config array

Name-value pairs that will be used to initialize the object properties

 

                public function __construct($config = [])
{
    if (!empty($config)) {
        Yii::configure($this, $config);
    }
    $this->init();
}
__get() public method

Defined in: yii\base\BaseObject::__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

See also __set().

public mixed __get ( $name )
$name string

The property name
return mixed

The property value
throws yii\base\UnknownPropertyException

if the property is not defined
throws yii\base\InvalidCallException

if the property is write-only

 

                public function __get($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter();
    } elseif (method_exists($this, 'set' . $name)) {
        throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
    }
    throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
__isset() public method

Defined in: yii\base\BaseObject::__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

See also https://www.php.net/manual/en/function.isset.php.

public boolean __isset ( $name )
$name string

The property name or the event name
return boolean

Whether the named property is set (not null).

 

                public function __isset($name)
{
    $getter = 'get' . $name;
    if (method_exists($this, $getter)) {
        return $this->$getter() !== null;
    }
    return false;
}
__set() public method

Defined in: yii\base\BaseObject::__set()

Sets value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

See also __get().

public void __set ( $name, $value )
$name string

The property name or the event name
$value mixed

The property value
throws yii\base\UnknownPropertyException

if the property is not defined
throws yii\base\InvalidCallException

if the property is read-only

 

                public function __set($name, $value)
{
    $setter = 'set' . $name;
    if (method_exists($this, $setter)) {
        $this->$setter($value);
    } elseif (method_exists($this, 'get' . $name)) {
        throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
    } else {

    }
}
__unset() public method

Defined in: yii\base\BaseObject::__unset()

Sets an object property to null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).
