Smarty

[boyer]

Hey everyone!

I'm sure there's a simple way to accomplish what I'm looking to do here, and I'm just missing it...

Let's say I have a controller class that extends Smarty, and does all my work for me. At the end of the controllers work, it calls $this->display('myTemplate.tpl'); and we're off to the browser.

Let's say I've got an email inbox, and I've just made a GET request to delete message #999. I pass the parms like this: inbox.php?action=delete&messageId=999.

My controller does it's thing, deletes the message, gets the messages from the db, then displays them back to the user. The problem is, I still have "&action=delete&messageId=999" in the URL bar. If the user refreshes, they'll get an error message stating that message doesn't exist etc etc.

Is there any easy way in Smarty to remove those parameters from GET?
I've tried doing it directly in php before I call $this->display() by doing $_GET["action'] = "" or unset($_GET["action"]) or $_GET["action"] = null, but none of these things do what I need them to.

I really don't want to resort to doing all my actions via POST (means adding more javascript).

Thanks for the help!

Have you tried to explode() the url with "?" and redirect to "new" URI ?

Well atcuall I already have some convenience methods written to take the get args I currently have, add/remove/modify them, then build out the new string that would be appended to the URI.

Trouble is, I need my template output to display. I don't want to redirect to another controller first.

Can you think of a usage example where at the end of my controller, but before I call $this->display() that I could implement this?

I don't think you want to modify the $_GET array (at the server), because that would not change the fact that when the user presses refresh (at the client) the browser will request the same page as last time. You will have to forward them to a new page either using this:

http://php.net/manual/en/function.header.php

or this:

You could redirect to a generic "Your message has been deleted" page.

But, the real problem is that those types of non-repeatable requests should not be made using GET they should be made using POST.
