scriptA.php has a form that sends POST to scriptB.php. scriptB.php also a form that sends POST data to scriptC.php. When I print_r($_POST) on scriptC.php, the data is not scriptB's but scriptA's!

ScriptB even has a call to unset($_POST) which seems to work. It appears to work because on scriptB ther is also a print_r($_POST) after that unset($_POST) which shows it is empty.

So how does scriptC still end up with scriptA's POST data? I've unset() it, and submitted a new POST form... but it's not going away! I'm going crazy here.

Tried multiple browsers, logging in and out of the site... Nothing has worked so far.

scriptA.php

<form method="post" action="scriptB.php">
{form inputs}
</form>

scriptB.php:

<?php

unset($_POST);
print_r($_POST); //blank

?>
<form method="post" action="scriptC.php">
{form inputs, different than scriptA}
</form>

scriptC.php:

<?php

print_r($_POST); // displays data fields from scriptA instead of scriptB

?>

Use $_REQUEST instead of $_POST.
