To prevent any possible javascript injection problems
escape the url with json_encode
This way, you’re sure the $url won’t break the javascript syntax

echo ‘window.location = ‘.json_encode($url);

Cheers

@nnc: Thanks for the simplification. I was planning on putting the javascript code at the top of all my layouts until I read your comment.

@cakebaker: Thanks for the original idea. I haven’t been able to find any server-side solutions that work correctly.

@Aaron: Hm, strange, it works here. It looks like the controller is not set. Does the startup() method get called?

When I run this code, I get the following error:

Fatal error: Call to a member function redirect() on a non-object in /path/to/app/controllers/components/component.php on line 18

Line 18, in my case is:

$this->controller->redirect(‘/users/login’);

Any ideas? I’m pulling my hair out.

If all you want to do is redirect, I find it much more convenient to eliminate if (isset($url)) from views. To do that, I modified goto function to following:

function goto($url)
{
if ($this->RequestHandler->isAjax()) {
echo ”;
echo ‘window.location = “‘.$url.’”‘;
echo ”;
exit();
} else {
$this->controller->redirect($url);
}
}

I use this in admin section to redirect to login form if session has expired.

Thanks for this great site cakebaker.

The startup function is automatically called by Cake, you do not have to call it yourself.

We must call it manually before redirect, it right ?
