Controlling user flow with forms

[Jason]

I have a screen where I ask the user their payment type. Once they
select the payment type either check or credit card, I would like them
to go to a seperate checkout page. How can I write a bit of code to
make .php re-direct them to the proper page? (I considered doing this
with Javascript, but would rather keep it all in .php)

Thanks,

Are you validating the credit card before you redirect them

Two things you can do.
1) (my preferred method): Just have it on the same page, and output
different things on that page based on the payment type.

for example:
if ($_GET['paymentType'] == "creditcard ")
{
// output the form for credit card crap
}
else
{
// output for check etc
}

2) If they are radically different and it really is appropriate to send them
to different actual pages, you can do (at the top of the page, before
*anything* is outputted, including blank spaces/lines etc)

<?php
// process whatever you need to, but output NOTHING
if ($_GET['procType'] == "creditcard ")
header("Locatio n: http://www.mysite.com/creditcard.php" );
else
header("Locatio n: http://www.mysite.com/otherpayment.ph p");
?>

What's the problem in just having a "Check" and a "Credit Card" link in
plain HTML?
