Property Details

Hide inherited properties

$defaults public property

The default GET parameters (name => value) that this rule provides. When this rule is used to parse the incoming request, the values declared in this property will be injected into $_GET.

'controller' => 'default',
    
'action' => 'index',
]
$mode public property

A value indicating if this rule should be used for both request parsing and URL creation, parsing only, or creation only. If not set or 0, it means the rule is both request parsing and URL creation. If it is PARSING_ONLY, the rule is for request parsing only. If it is CREATION_ONLY, the rule is for URL creation only.

__call() public method

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

__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 = [])

        Yii::configure($this, $config);
    }
    $this->init();
}

            
__get() public method

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

}

            
__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

    }
    return false;
}

            
__set() public method

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