Re: Confusing POST behavior -- doing it twice?

Hi Shelly,

Please include an else:

// Verify that a Zip code is numeric and is five digits

if (!is_numeric($_POST($zip)) strlen($_POST($zip)) != 5) then {
$_SESSION['Error'] = "an error description";
header("Location: thisSite.php");
}else {
header("Location: anotherSite.php");
}

Let me know how you do.

Cheers,

DXTrim
