/** |

|
|
|
* Creates a URL for the given route. |
|
32
|
|
|
* |
|
33
|
|
|
* This method will use [[\yii\web\UrlManager]] to create a URL. |
|
34
|
|
|
* |
|
35
|
|
|
* You may specify the route as a string, e.g., `site/index`. You may also use an array |
|
36
|
|
|
* if you want to specify additional query parameters for the URL being created. The |
|
37
|
|
|
* array format must be: |
|
38
|
|
|
* |
|
39
|
|
|
* ```php |
|
40
|
|
|
* // generates: /index.php?r=site/index¶m1=value1¶m2=value2 |
|
41
|
|
|
* ['site/index', 'param1' => 'value1', 'param2' => 'value2'] |
|
42
|
|
|
* ``` |
|
43
|
|
|
* |
|
44
|
|
|
* If you want to create a URL with an anchor, you can use the array format with a `#` parameter. |
|
45
|
|
|
* For example, |
|
46
|
|
|
* |
|
47
|
|
|
* ```php |
|
48
|
|
|
* // generates: /index.php?r=site/index¶m1=value1#name |
|
49
|
|
|
* ['site/index', 'param1' => 'value1', '#' => 'name'] |
|
50
|
|
|
* ``` |
|
51
|
|
|
* |
|
52
|
|
|
* A route may be either absolute or relative. An absolute route has a leading slash (e.g. `/site/index`), |
|
53
|
|
|
* while a relative route has none (e.g. `site/index` or `index`). A relative route will be converted |
|
54
|
|
|
* into an absolute one by the following rules: |
|
55
|
|
|
* |
|
56
|
|
|
* - If the route is an empty string, the current [[\yii\web\Controller::route|route]] will be used; |
|
57
|
|
|
* - If the route contains no slashes at all (e.g. `index`), it is considered to be an action ID |
|
58
|
|
|
* of the current controller and will be prepended with [[\yii\web\Controller::uniqueId]]; |
|
59
|
|
|
* - If the route has no leading slash (e.g. `site/index`), it is considered to be a route relative |
|
60
|
|
|
* to the current module and will be prepended with the module's [[\yii\base\Module::uniqueId|uniqueId]]. |
|
61
|
|
|
* |
|
62
|
|
|
* Starting from version 2.0.2, a route can also be specified as an alias. In this case, the alias |
|
63
|
|
|
* will be converted into the actual route first before conducting the above transformation steps. |
|
64
|
|
|
* |
|
65
|
|
|
* Below are some examples of using this method: |
|
66
|
|
|
* |
|
67
|
|
|
* ```php |
|
68
|
|
|
