Route URL with GET parameters to cleaner URL

[eluser]vendiddy[/eluser]
Hi, I am trying to figure out how to reroute a url like application/test?token=123 to a url like application/test/123. This is because the Zend_Gdata library needs to send an authentication token back to a method of my controller in the form of a GET parameter.

Code:

function test_gcal_auth()
{
    $this->load->library('zend');
    $this->zend->load('Zend/Gdata/Calendar');
    $this->zend->load('Zend/Gdata/AuthSub');        
    $scope = 'http://www.google.com/calendar/feeds/';
    $secure = true;
    $session = true;
    $next = $this->config->item('base_url') . 'system/umdcal/test.php';
    $url = Zend_Gdata_AuthSub::getAuthSubTokenUri($next, $scope, $secure, $session);
    echo sprintf('<a href="%s">Login</a>', $url);
}

I currently use a hack where I set the next url to be test.php. In test.php, I extract the GET parameter and redirect to the correct method in my application controller. (As seen below.)

Code:

$token = $_GET['token'];
header("Location: http://localhost/umdcal.php/application/test/$token");

Does anyone know of a cleaner solution? I tried adding a regex pattern in routes.php but wasn't able to get it working.

Thanks!

Im confused about what your trying to achieve and where you are trying to achieve it.

You seem to have /application/ and /system/ in your URL's. This is not normal CI behaviour.

Anyway, the following code would work:

Code:

<?php
class Whatever extends Controller() {

    function method($token = '') {
        $this->load->helper('url');
        redirect('application/test/'.$token);
    }

}
?>

If you could explain your code more I could help you further

Sorry for the confusion, but my controller is named application. (Is there a standard for naming the default controller?)

Basically, if I paste this URL into my browser:
http://localhost/umdcal.php/application/...Tq_v____8B
I get the 404 page even though I have a function called test in my application controller.

Instead of getting this 404 page, I would like for the above URL to automatically redirect to
http://localhost/umdcal.php/application/...Tq_v____8B

I don't think I can use an alternative to the GET parameter. This is because Google's authentication works by redirecting to a page of my choice and attaching the token as a GET parameter.

Thanks again!

Hi Vendiddy,

I set up a referral system on one of my CI sites, which allowed the user to take any page / controller / method etc and attach a ?ref=userid to it.

What I did assumes that query_string is still set to OFF for CI.

in the pre_controller hook, you can still process $_GET as CI hasn't gotten ahold of it yet.

Here is what I would do: at this point in time there are only two classes loaded for CI, so you have to use native PHP code for everything
I would actually recomend only having this run on the page that can accept this as well.
pre_controller hook:

Code:

if (isset($_GET['token']))
{
    header("Location: /umdcal.php/application/test/" . urlencode($_GET['token']));
    unset($_GET['token']);
}

... or if you think of something else besides a header redirect. Make sure you do the unset() though, that way CI doesn't see it, as it would throw a 404 as you are currently experiencing.

One other thing to try.

What happens if you feed google an end slash (after test)

IE
http://localhost/umdcal.php/application/test/

Does CI then pass:
?token=CPPu5rz7ABCCf-Tq_v____8B

to the controller? Or does it try and make a url out of it?

IF it does pass that, you could simply strip the ?token= off of it and you have your token string.


This would, of course, require you to add additional 'allowed uri characters'

Hi,

I'm having the same problem. Is there another workaround that doesn't have to use any hook ? I'm afraid it will have performance problem.

Thanks,
