You can use a token to check if a form has been sent before...
<?
class formReload {
var $tokenarray = '__token';
var $tokenname = '__token';
function createToken()
{
$tok = md5(uniqid("mytoken"));
return sprintf("<input type='hidden' name='%s'
value='%s'>",$this->tokenname,htmlspecialchars($tok));
}
function easyCheck()
{
$tok = $_REQUEST[$this->tokenname];
if (isset($_SESSION[$this->tokenarray][$tok]))
{
return false;
}
else
{
$_SESSION[$this->tokenarray][$tok] = true;
return true;
}
}
}
?>

Subject: Re: [PHP] Problems with $_POST
Hi
What is the primary key in your tble? Using tht primary key check for
duplicate entry... Theres no way u can change the posted data ... so even if
u reset $_POST['submit'] after the insert operation is done, next time u
refresh it will be set and hence will duplicate...so check for duplicate
entries urself only based on primary key or unique values in ur table.
Hope this helps
Cheers

I have a FORM for entering data into a DB.
I use:
...
...
if ($_POST['submit'] == 'Register') {
...
code for INSERT into DB.
This works OK, but if I REFRESH the page, it duplicates the "dataset" in
the table.
How can I reset $_POST['submit'] so it don't make this happen?
