Okay, I have a form with two textboxes ("name" and "comment") and a submit button. When they click the submit button, I want to call a PHP function (see image) with the values of the textboxes and reload the page. I know I could use method="get" and $_GET['...'], but I don't want to use that because then it will redo something if they refresh, and I don't want it to redo that. I made a little thing to show you what I want it like. Otherwise, if you know what I could do about the $_GET['...'] problem, that would be fine too.

CODE

and the php.

CODE

<?php
$comments = fopen('uicomments.txt','a+');
if (@$_POST['comment'] and @$_POST['name']) {
$comment = $_POST['comment'];
$name = $_POST['name'];
fwrite($comments, $user+":\n");
fwrite($comments,$comment+"\n");
$comments = fopen('uicomments.txt','a+');
}
rewind($comments);
while (!feof($comments)) {
echo fread($comments);
}
?>

i think thats what you were asking.

That's how my code is now. Everything works perfect, except when I submit and then refresh it says there's some POSTDATA and when I click okay it puts the message in again. So, after I've gotten the POSTDATA, is there anyway to clear the POSTDATA that keeps ( @$_POST['name'] and @$_POST['comment'] ) from evaluating to true when you refresh?

You could try

CODE

$_POST['name'] = null;
$_POST['comment'] = null;

//If null doesn't work, try "".

after doing all your PHP functions.

It may not work, as I don't know if you can manually change POST and GET variables. Give it a shot.

unset($_POST);

I tried that Shmeeps, it will set them but it doesn't make a difference. Same with unset(); it will unset $_POST but it still doesn't make a difference. Maybe you could suggest a better way to make a "comment system" which wouldn't have this problem?

Just change it to make it check if there is an identical thing before it.

I would say take the form values, and send them to a page that enters them, then redirects back to the first page.

Hex yeah!

I believe this is how most forums do it. At least, that how the one I make is doing it.
