Source Code framework/web/CWebApplication.php
CWebApplication extends CApplication by providing functionalities specific to Web requests.

CWebApplication manages the controllers in MVC pattern, and provides the following additional core application components:
  • urlManager: provides URL parsing and constructing functionality;
  • request: encapsulates the Web request information;
  • session: provides the session-related functionalities;
  • assetManager: manages the publishing of private asset files.
  • user: represents the user session information.
  • themeManager: manages themes.
  • authManager: manages role-based access control (RBAC).
  • clientScript: manages client scripts (javascripts and CSS).
  • widgetFactory: creates widgets and supports widget skinning.


User requests are resolved as controller-action pairs and additional parameters. CWebApplication creates the requested controller instance and let it to handle the actual user request. If the user does not specify controller ID, it will assume defaultController is requested (which defaults to 'site').

Controller class files must reside under the directory controllerPath (defaults to 'protected/controllers'). The file name and the class name must be the same as the controller ID with the first letter in upper case and appended with 'Controller'. For example, the controller 'article' is defined by the class 'ArticleController' which is in the file 'protected/controllers/ArticleController.php'.

Property Details

assetManager property read-only

the asset manager component

authManager property read-only

the authorization manager component

catchAllRequest property
public array $catchAllRequest;

the configuration specifying a controller which should handle all user requests. This is mainly used when the application is in maintenance mode and we should use a controller to handle all incoming requests. The configuration specifies the controller route (the first element) and GET parameters (the rest name-value pairs). For example,

array(
    'offline/notice',
    'param1'=>'value1',
    'param2'=>'value2',
)
Defaults to null, meaning catch-all is not effective.

clientScript property read-only

Returns the client script manager.

controller property
public CController getController()
public void setController(CController $value)

the currently active controller

controllerMap property
public array $controllerMap;

mapping from controller ID to controller configurations. Each name-value pair specifies the configuration for a single controller. A controller configuration can be either a string or an array. If the former, the string should be the class name or class path alias of the controller. If the latter, the array must contain a 'class' element which specifies the controller's class name or class path alias. The rest name-value pairs in the array are used to initialize the corresponding controller properties. For example,

array(
  'post'=>array(
     'class'=>'path.to.PostController',
     'pageTitle'=>'something new',
  ),
  'user'=>'path.to.UserController',
)


Note, when processing an incoming request, the controller map will first be checked to see if the request can be handled by one of the controllers in the map. If not, a controller will be searched for under the default controller path.

controllerNamespace property (available since v1.1.11)
public string $controllerNamespace;

Namespace that should be used when loading controllers. Default is to use global namespace.

controllerPath property
public string getControllerPath()
public void setControllerPath(string $value)

defaultController property
public string $defaultController;

the route of the default controller, action or module. Defaults to 'site'.

layout property

public void setLayoutPath(string $path)

the root directory of layout files. Defaults to 'protected/views/layouts'.

session property read-only

the session component

systemViewPath property

the theme used currently. Null if no theme is being used.

themeManager property read-only

the theme manager.

user property read-only
public CWebUser getUser()

the user session information

viewPath property
public string getViewPath()
public void setViewPath(string $path)

the root directory of view files. Defaults to 'protected/views'.

viewRenderer property read-only

Returns the view renderer. If this component is registered and enabled, the default view rendering logic defined in CBaseController will be replaced by this renderer.

widgetFactory property read-only (available since v1.1)

Returns the widget factory.

}

Creates a controller instance based on a route. The route should contain the controller ID and the action ID. It may also contain additional GET variables. All these must be concatenated together with slashes.

This method will attempt to create a controller in the following order:

  1. If the first segment is found in controllerMap, the corresponding controller configuration will be used to create the controller;
  2. If the first segment is found to be a module ID, the corresponding module will be used to create the controller;
  3. Otherwise, it will search under the controllerPath to create the corresponding controller. For example, if the route is "admin/user/create", then the controller will be created using the class file "protected/controllers/admin/UserController.php".
