Class yii\web\UrlManager

Inheritanceyii\web\UrlManager » yii\base\Component » yii\base\BaseObject
Implementsyii\base\Configurable
Available since version2.0
Source Code https://github.com/yiisoft/yii2/blob/master/framework/web/UrlManager.php

UrlManager handles HTTP request parsing and creation of URLs based on a set of rules.

UrlManager is configured as an application component in yii\base\Application by default. You can access that instance via Yii::$app->urlManager.

You can modify its configuration by adding an array to your application config under components as it is shown in the following example:

'urlManager' => [
    'enablePrettyUrl' => true,
    'rules' => [
        // your rules go here
    ],
    // ...
]

Rules are classes implementing the yii\web\UrlRuleInterface, by default that is yii\web\UrlRule. For nesting rules, there is also a yii\web\GroupUrlRule class.

For more details and usage information on UrlManager, see the guide article on routing.

Property Details

$baseUrl public property

The base URL that is used by createUrl() to prepend to created URLs.

public string getBaseUrl ( )
public void setBaseUrl ( $value )
$cache public property

The cache object or the application component ID of the cache object. Compiled URL rules will be cached through this cache object, if it is available.

After the UrlManager object is created, if you want to change this property, you should only assign it with a cache object. Set this property to false if you do not want to cache the URL rules.

Cache entries are stored for the time set by $defaultDuration in the cache configuration, which is unlimited by default. You may want to tune this value if your $rules change frequently.

$cacheKey protected property (available since version 2.0.8)

The cache key for cached rules

protected string $cacheKey __CLASS__
$enablePrettyUrl public property

Whether to enable pretty URLs. Instead of putting all parameters in the query string part of a URL, pretty URLs allow using path info to represent some of the parameters and can thus produce more user-friendly URLs, such as "/news/Yii-is-released", instead of "/index.php?r=news%2Fview&id=100".

public boolean $enablePrettyUrl false
$enableStrictParsing public property

Whether to enable strict parsing. If strict parsing is enabled, the incoming requested URL must match at least one of the $rules in order to be treated as a valid request. Otherwise, the path info part of the request will be treated as the requested route. This property is used only when $enablePrettyUrl is true.

$hostInfo public property

The host info (e.g. http://www.example.com) that is used by createAbsoluteUrl() to prepend to created URLs.

public string getHostInfo ( )
public void setHostInfo ( $value )
$normalizer public property (available since version 2.0.10)

The configuration for yii\web\UrlNormalizer used by this UrlManager. The default value is false, which means normalization will be skipped. If you wish to enable URL normalization, you should configure this property manually. For example:

[
    'class' => 'yii\web\UrlNormalizer',
    'collapseSlashes' => true,
    'normalizeTrailingSlash' => true,
]
$routeParam public property

The GET parameter name for route. This property is used only if $enablePrettyUrl is false.

public string $routeParam 'r'
$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 for creating and parsing URLs when $enablePrettyUrl is true. This property is used only if $enablePrettyUrl is true. Each element in the array is the configuration array for creating a single URL rule. The configuration will be merged with $ruleConfig first before it is used for creating the rule object.

A special shortcut format can be used if a rule only specifies pattern and route: 'pattern' => 'route'. That is, instead of using a configuration array, one can use the key to represent the pattern and the value the corresponding route. For example, 'post/<id:\d+>' => 'post/view'.

For RESTful routing the mentioned shortcut format also allows you to specify the HTTP verb that the rule should apply for. You can do that by prepending it to the pattern, separated by space. For example, 'PUT post/<id:\d+>' => 'post/update'. You may specify multiple verbs by separating them with comma like this: 'POST,PUT post/index' => 'post/create'. The supported verbs in the shortcut format are: GET, HEAD, POST, PUT, PATCH and DELETE. Note that mode will be set to PARSING_ONLY when specifying verb in this way so you normally would not specify a verb for normal GET request.

Here is an example configuration for RESTful CRUD controller:

[
    'dashboard' => 'site/index',

    'POST <controller:[\w-]+>' => '<controller>/create',
    '<controller:[\w-]+>s' => '<controller>/index',

    'PUT <controller:[\w-]+>/<id:\d+>'    => '<controller>/update',
    'DELETE <controller:[\w-]+>/<id:\d+>' => '<controller>/delete',
    '<controller:[\w-]+>/<id:\d+>'        => '<controller>/view',
];

Note that if you modify this property after the UrlManager object is created, make sure you populate the array with rule objects instead of rule configurations.

public array $rules = []
$scriptUrl public property

The entry script URL that is used by createUrl() to prepend to created URLs.

public string getScriptUrl ( )
public void setScriptUrl ( $value )
$showScriptName public property

Whether to show entry script name in the constructed URL. Defaults to true. This property is used only if $enablePrettyUrl is true.

public boolean $showScriptName true
$suffix public property

The URL suffix used when $enablePrettyUrl is true. For example, ".html" can be used so that the URL looks like pointing to a static HTML page. This property is used only if $enablePrettyUrl is true.

public string $suffix null

Method Details

addRules() public method

Adds additional URL rules.

This method will call buildRules() to parse the given rule declarations and then append or insert them to the existing $rules.

Note that if $enablePrettyUrl is false, this method will do nothing.

public void addRules ( $rules, $append true )
$rules array

The new rules to be added. Each array element represents a single rule declaration. Please refer to $rules for the acceptable rule format.

$append boolean

Whether to add the new rules by appending them to the end of the existing rules.

buildRules() protected method

return yii\web\UrlRuleInterface[]

The rule objects built from the given rule declarations

throws yii\base\InvalidConfigException

if a rule declaration is invalid

canBeCached() protected method (available since version 2.0.12)

Returns the value indicating whether result of createUrl() of rule should be cached in internal cache.

See also:

protected boolean canBeCached ( yii\web\UrlRuleInterface $rule )
$rule yii\web\UrlRuleInterface
return boolean

true if result should be cached, false if not.

createAbsoluteUrl() public method

Creates an absolute URL using the given route and query parameters.

This method prepends the URL created by createUrl() with the $hostInfo.

Note that unlike yii\helpers\Url::toRoute(), this method always treats the given route as an absolute route.

See also createUrl().

public string createAbsoluteUrl ( $params, $scheme null )
$params string|array

Use a string to represent a route (e.g. site/index), or an array to represent a route with query parameters (e.g. ['site/index', 'param1' => 'value1']).

$scheme string|null

The scheme to use for the URL (either http, https or empty string for protocol-relative URL). If not specified the scheme of the current request will be used.

return string

The created URL

createUrl() public method

Creates a URL using the given route and query parameters.

You may specify the route as a string, e.g., site/index. You may also use an array if you want to specify additional query parameters for the URL being created. The array format must be:

// generates: /index.php?r=site%2Findex&param1=value1&param2=value2
['site/index', 'param1' => 'value1', 'param2' => 'value2']

If you want to create a URL with an anchor, you can use the array format with a # parameter. For example,

// generates: /index.php?r=site%2Findex&param1=value1#name
['site/index', 'param1' => 'value1', '#' => 'name']

The URL created is a relative one. Use createAbsoluteUrl() to create an absolute URL.

Note that unlike yii\helpers\Url::toRoute(), this method always treats the given route as an absolute route.
