UrlRule represents a rule used by yii\web\UrlManager for parsing and generating URLs.

To define your own URL parsing and creation logic you can extend from this class and add it to yii\web\UrlManager::$rules like this:

'rules' => [
    ['class' => 'MyUrlRule', 'pattern' => '...', 'route' => 'site/index', ...],
    // ...
]

ConstantValueDescriptionDefined By
CREATE_STATUS_PARAMS_MISMATCH 4 Represents the unsuccessful URL generation by last createUrl() call, because of mismatched or missing parameters. yii\web\UrlRule

Property Details

$createStatus protected property (available since version 2.0.12)

Status of the URL creation after the last createUrl() call.

protected integer|null $createStatus = null
$createUrlStatus public property

Status of the URL creation after the last createUrl() call. null if rule does not provide info about create status. This property is read-only.

public null|integer $createUrlStatus = null
$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.

public array $defaults = []
$encodeParams public property

A value indicating if parameters should be url encoded.

public boolean $encodeParams = true
$host public property

The pattern used to parse and create the host info part of a URL (e.g. http://example.com).

See also $pattern.

public string $host = null
$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.

public integer $mode = null
$name public property

The name of this rule. If not set, it will use $pattern as the name.

public string $name = null
$normalizer public property (available since version 2.0.10)

The configuration for yii\web\UrlNormalizer used by this rule. If null, yii\web\UrlManager::$normalizer will be used, if false, normalization will be skipped for this rule.

$pattern public property

The pattern used to parse and create the path info part of a URL.

See also:
