Its a fairly long script but this is a basic rundown of the mechanics.
some_page.php
-----------------------------
<?php
/* user is sent here from another page, grab foo and bar from the url */
$foo = $_GET['foo'];
$bar = $_GET['bar'];
select * from database where this='$foo' and that='$bar';
$result = mysql_query(....);
if ($result === false)
{
trigger_error(...); // <- this is where it breaks for the other guy
but not for me...
}
if (isset($_POST['submit']))
{
insert into database (col1, col2) values ('$foo', '$bar');
}
else
{
echo '<form action="some_page.php" method="post">';
echo '<input type="hidden" name="foo" value="' . $foo . '">';
echo '<input type="hidden" name="bar" value="' . $bar . '">';
echo '<input type="submit" name="submit" value="Submit">';
}
?>
Now as it stands, initially it would work fine, but when the form is
submitted, it would break, because 'foo' and 'bar' are in $_POST.
For some reason, this is working on my boxes with register_globals set
to off.
