Yii Framework Analysis Note 12: Topic Management

The control of Yii topics is managed by Cthememanager and Ctheme, Cthememanager is registered as a core component when the application is initialized, and the default path for the theme is app/themes/.

Theme Configuration
Because the theme component is registered at the time of application initialization, its configuration and aspects, such as having a custom1 theme under app/themes/
By adding ' theme ' + ' Custom1 ' key-value pairs in the main profile, the Cwebapplication::settheme ($value) initialization theme name will be called when the subject is registered.

Get topics
Topic acquisition Gets the path of the view file from the controller rendering view, by viewing the name passed by the action method

[PHP]View Plaincopy

2. Ccontroller::getviewfile ()
4. Public function Getviewfile ($viewName)
6. {
10. if ($theme =yii::app ()->gettheme ())!==null && ($viewFile =$theme->getviewfile ($ This,$viewName))!==false)
12. return $viewFile;
14. $moduleViewPath =$basePath =yii::app ()->getviewpath ();
18. if ($module =$this->getmodule ())!==null)
20. $moduleViewPath =$module->getviewpath ();
22. return $this->resolveviewfile ($viewName,$this->getviewpath (),$basePath,$  Moduleviewpath);
24. }

16. Public function Getviewfile ($controller,$viewName)

26. return $controller->resolveviewfile ($viewName,$this->getviewpath ().' /‘.  $controller->getuniqueid (),$this->getviewpath (),$moduleViewPath);
28. }

Back to Ccontroller get the specific view file path, the view name has three special names
1, starting with//is relative to the application level of the view path
2. Start with/begin with a basic view path relative to module
3. xx.xx is an alias view

38. }
40. Else if (strpos ($viewName,'. '))
42. $viewFile =yii::getpathofalias ($viewName);
44. Else
46. $viewFile =$viewPath. Directory_separator.   $viewName;
50. if (is_file ($viewFile. $extension))
52. return Yii::app ()->findlocalizedfile ($viewFile.   $extension);

56. return Yii::app ()->findlocalizedfile ($viewFile.  php ');
58. Else
60. return false;
62. }

In the view file, a reference to the style JS and the picture in the theme is required to use the Yii::app ()->theme->baseurl as the BaseURL.
