Oct29How to get current theme name or theme working in cakephp
Making theme set and available by setting theme related properties in controller
Prior to cakephp 2.0
class UserController extends AppController {
var $view = 'Theme'; //tells controller to use "ThemeView" class instead of the default "View" class
var $theme = 'WhiteFeather'; //name of the theme folder which is supposed to be placed at views/themed/
}
Cakephp 2.0
class UserController extends AppController {
public $viewClass = 'Theme'; //tells controller to use "ThemeView" class instead of the default "View" class
public $theme = 'WhiteFeather'; //name of the theme folder which is supposed to be placed at View/Themed
}
Theme can be changed within a controller function or in beforeFilter/beforeRender by overriding the theme property:
$this->theme = 'BlackFeather';
