PHP Class yii\web\UrlRule

To define your own URL parsing and creation logic you can extend from this class and add it to [[UrlManager::rules]] like this: ~~~ 'rules' => [ ['class' => 'MyUrlRule', 'pattern' => '...', 'route' => 'site/index', ...], ... ] ~~~

Public Properties

Property Type Description
$defaults 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.
$encodeParams a value indicating if parameters should be url encoded.
$host the pattern used to parse and create the host info part of a URL (e.g. http://example.com).
$mode 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.
$name the name of this rule. If not set, it will use [[pattern]] as the name.
$normalizer the configuration for UrlNormalizer used by this rule. If null, [[UrlManager::normalizer]] will be used, if false, normalization will be skipped for this rule.
$pattern On the rule initialization, the [[pattern]] matching parameters names will be replaced with [[placeholders]].
$route the route to the controller action
$suffix the URL suffix used for this rule. For example, ".html" can be used so that the URL looks like pointing to a static HTML page. If not, the value of [[UrlManager::suffix]] will be used.
$verb the HTTP verb (e.g. GET, POST, DELETE) that this rule should match. Use array to represent multiple verbs that this rule may match. If this property is not set, the rule can match any verb. Note that this property is only used when parsing a request. It is ignored for URL creation.

Protected Properties

Property Type Description
$placeholders list of placeholders for matching parameters names. Used in UrlRule::parseRequest, UrlRule::createUrl. On the rule initialization, the [[pattern]] parameters names will be replaced with placeholders. This array contains relations between the original parameters names and their placeholders. The array keys are the placeholders and the values are the original names.
