Deleting POST vars

Sergey

I've page that pass POST data to itself.
After its processing in script, I delete it by

unset($var, $HTTP_POST_VARS['var']);
echo $var.'<br>'.$HTTP_POST_VARS['var']; // check only for
testing purposes and see nothing, that's I need

But when I reload page in browser, its still there.
So how can I delete it completely?

Thanks.

im pretty sure unset is used for session vars not post vars but to delete to just go
$_POST['var'] = "";

that should work

I'm not sure but your problem seems to be a cache problem so you may try this

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header("Pragma: no-cache");

you can also sort it out with META tag...

No, unset is for all kind of var, session, local, global, post var....
unset -- Unset a given variable

If you're telling your browser to refresh the response from a form submission, it will resubmit the form data:

Submit a form
Get a response
Server empties out $HTTP_POST_VARS
Hit refresh (browser resubmits - $HTTP_POST_VARS filled out again).

In other words, when you tell the browser to reload the page, it does it by repeating its previous request - form data and all.

So mr. Weedpacket, you say, that I can't fix it and it will appear again and again?

FYI, unset does not seem to work with session objects.

Sort of. Just don't refresh....browse to the beginning of the form anew......

This is a known bug. See here.

I'm having the same problem - As explained in this post:

http://www.phpbuilder.com/board/showthread.php?threadid=10220050

The Value that my form sends is: $SubmitForm

I tried $_POST['SubmitForm'] = "";

Doesn't work. Unset is broke and IT doesn't work...

What to do, what to do...
