Request::$controller in Kohana

Question

Why I cannot request a used controller's name from the View?

For example, someview.php contains:

<?php echo Request::$controller; ?>

Kohana shows the error: “ErrorException [ Fatal Error ]: Access to undeclared static property: Request::$controller”

Why? What's wrong?

It is needed for me for doing this:

<?php if (Request::$controller != 'index') { ?> <a href="/">Example.com</a> <?php } else { ?> Example.com <?php } ?>

Answer 1

Do this instead, on the controller :

View::bind_global('controller', $this->request->param('controller'));

Then you can access $controller on any view.

Answer 2

I would do as yoda suggested, however I would probably put that logic in the controller as well.

I assume you want a link back to home?

$link = (Request::$controller != 'index') ? '<a href="/">Example.com</a>' : 'Home';
$this->template->set_global('homeLink', $link);

Don't forget too you can build links from your routes by using Route::get() or one of its friends.

In Kohana 3.1

<? if (Request::current()->controller !== 'index') : ?>

give the "ErrorException [ Notice ]: Undefined property: Request::$controller". then i simply using Request::current()->controller() in view acceptable/ best practice/ optimal performance?

<? if (Request::current()->controller() !== 'index') : ?> 

    <a href="<?= URL::site() ?>">Example.com</a> 

<? else : ?> 

    Example.com 

<?  endif; ?>

Answer 4

Request should be accessed by it's static methods, there's no need to define additional static properties || global view vars to get it.

Request::instance() will return the the main request instance ('mother instance'). Request::current() will return the instance of the currently active request, the same thing you can access with $this->request in Controller.

<? if (Request::current()->controller !== 'index') : ?> 

    <a href="<?= URL::site() ?>">Example.com</a> 

<? else : ?> 

    Example.com 

<?  endif; ?>

Kohana 3.2: In the controller, paste this (I find it really really stupid that you can't use bind_global)

View::set_global('controller', $this->request->current()->controller());

Then in the view, you can use:

echo ( $controller );
