Form Mail variable pass on redirect

Hi guys/gals. This is a repost but I couldnt’ get a reponse earlier.

I am having difficulty using a godaddy mail form and passing the inputed values to a redirected page. I want to send the first name and last name that the person inputs into the form, to the thank you page.

[B]***inputpage.php code***[/B]
[COLOR=”red”]form action=”gdform.php” method=post>
<input type=”hidden” name=”subject” value=”Submission Data” />
<input type=”hidden” name=”redirect” value=”thankyou.php?First_Name=’.$firstname’&Last_Name=’.$lastname'” />

[B]***thankyou.php code***[/B]
$firstname = $_GET[‘First_Name’];
$lastname = $_GET[‘Last_Name’];[/COLOR]

I tried using this;

[COLOR=”Blue”]header(“Location: thankyou.php?First_Name={$_POST[‘First_Name’]}&Last_Name={$_POST[‘Last_Name’]}”);[/COLOR]

and this;

[COLOR=”Blue”]<input type=”hidden” name=”redirect” value=”thankyou.php?First_Name=’.$firstname’&Last_Name=’.$lastname'” />[/COLOR]

and this;

[COLOR=”Blue”]<input type=”hidden” name=”redirect” value=”thankyou.php?First_Name={$_POST[‘First_Name’]}&Last_Name={$_POST[‘Last_Name’]}” />[/COLOR][/QUOTE]

All I receiving are the actual characters behind the “=” instead of the value itself. Any help is appreciated.

Also in #PHP _↴
