But a refresh button is basically a "retry the last operation" so it's
not surprising the same information is sent again.
The correct solution here is to use the technique mentioned by Satyam.
Bascially:
<form action="handler.php" method="post">
blah
</form>
handler.php
<?php
if (!empty($_POST))
{
// Do stuff with $_POST, store it in a DB whatever.
header('Location: hander.php')
exit;
}
// Normal page output not referring in any way to $_POST
echo "Normal Page".
// If you have to present the data previously given in $_POST, then
// either store it in a DB or in a Session when handling the data above,
// then access the data from the DB or Session here.
// EOF
?>
This technique also means that the "back button" in the users browser is
not "broken" by posting forms... which is nice.
