锂框架：如何在布局中获取控制器名称

Question

I'm in a lithium layout file and I'd like to echo the name of the current controller (to use as a CSS class later). How can I obtain the current controller name?

Thanks, aeno

Answer 1

I assume you mean you are in a View?

If so, it's pretty simple to get the controller or other parts of the route/request ...

<?=$this->_request->controller;?>

That will get you the Controller but you can get just about anything from your route you'd need. So assuming you have a route like ...

Router::connect('/{:controller}/{:action}/{:id}');

You can use both of the following in your view:

<?=$this->_request->action;?>

<?=$this->_request->id;?>

Or you could have a fancier route like ..

Router::connect('/{:id}/{:area}/{:controller}/{:action}/');

This would be for a url like:

http://mysite.com/123/media/photos/edit/

Now you can do something like ...

<?=$this->_request->area;?> 

To get the "area" portion of the url, etc. You get the idea.

The following code can be used in any Lithium layout or view to look up the current Controller, convert it to a suitable CSS class name, and set it as the class attribute of a div:

<?php
    $controller = $this->request()->controller;
    $controller_css_class = strtolower(\lithium\util\Inflector::slug($controller));
?>

<div class="<?=$controller_css_class; ?>"></div>

The request class is documented here: http://li3.me/docs/lithium/action/Request
