Question

I have this controller which will simply change the language in a session so I can set it in the bootstrap.

Except I want to change ‘$this->_redirect ( ‘library/recipes/list’ );’ to be the URL of the page they are on. Ive tried a few functions and they dont seem to work.

Im a newbie Zend user, thanks!

class Library_LanguageswitchController extends Zend_Controller_Action {

public function init() {
  $this->_helper->layout->disableLayout ();
  $this->_helper->viewRenderer->setNoRender ();
 }

 public function switchAction() {
  $session = new Zend_Session_Namespace ( 'whatcould' );
  $session->language = $this->_getParam ( 'lang' );

  $this->_redirect ( 'library/recipes/list' );
 }

}

There is no built-in way to do this afaik. You want to redirect back to the referer, which may or may not be stored in $_SERVER['HTTP_REFERER'].

The best approach I can think of is writing a Zend_Controller_Action_Helper with a method signature like this

// Returns the referer from $_SERVER array or $fallback if referer is empty
public function getReferer($fallback);

// proxy to getReferer()
public function direct($fallback);

Then you could use

public function switchLanguageAction 
{
    // ... insert code to switch the language for this user ...
    $this->_redirect( $this->_helper->referer('/fallback/to/url') );
}

As an alternative, you could use a custom redirect helper that can achieve the same in one go.
