Javascript refresh

Anon

Hey all,

I got a poll running on my site, and it's working great. The problem is that I want the script that runs when you either vote or view the results to go back to the previous page.
So first I tried to make a returnurl, that gets sent with the voting, but that didn't work, since the variables were not all sent (blahblah.php?action=vote&returnurl=pollarchive.php?stage=2&poll_id=3

All the stuff behind returnurl should be considered as the url to go back to, but it only goes back to pollarchive.php?stage=2

Tried tons of stuff, but didn't get it to work.
So I just put
<meta http-equiv="Pragma" content="no-cache">
in the site and use the javascript:window.history.back().

But it still doesn't refresh. Can anybody plz help me?
only if I press the refresh button it works. But i don't want that ofcourse

Menno

Try using
header("location:lah.php?action=vote&returnurl=pollarchive.php?stage=2&poll_id=3");

This will automatically sned the user to page blahh with the values of the varibales you have also passed.

Warning though. header("location ...) will only work if there has been NOTHING written to the screen.

Make sure that nothing is echoed out and then you'll be fine

here's and example

<?
some code here

header("location:http://www.yahoo.com");

As soon as the code has been run the user is directed to yahoo.com. You can even append variables the the location you are going to

so the following would alose work

header("location:name.php?firest_name=mickey&last_name=mouse");

Hope this helps

If you have any questions just aska away

I think the problem is located in the fact that the returnurl parameter is supposed to contain multiple arguments.

header("location:lah.php?action=vote&returnurl=pollarchive.php?stage=2&poll_id=3");

In lah.php, the following would be set;

action = 'vote'
returnurl = 'pollarchive.php?stage=2'
poll_id = 3

Instead of;

action = 'vote'
returnurl = 'pollarchive.php?stage=2&poll_id=3'

So, what you need to do, is an urlencode;

$returnurl = "pollarchive.php?stage=$stage&poll_id=$pollid"; // or whatever
$returnurl = urlencode($returnurl);
header("Location: lah.php?action=vote&returnurl=$returnurl");

.. And you might need an urldecode() before sending the user on to $returnurl! Good luck.
