making payment after invoiced.

[nazca]

Sorry I'm a little lost,

Our company makes products like stickers. When you order from us you essentially make a description of what you want on your sticker. Our graphics artists sends the artwork and we bill those who haven't already fulfilled their invoice before shipment.

Customers can make payment now or they can select "pay after approved graphics." When they select pay after approved graphics the order goes through but there is never a button after that to make a payment through paypal. How do I get the paypal pay now button on the invoice for the correct total only if they selected this payment option and haven't already paid?



The only thing I can think of at the moment would be to fill their shopping cart with their exact order and then delete it from the database and forward them directly to the checkout page adding an admin comment that this is payment from a previous order that already has approved graphics.

But, that seems cumbersome and clunky as all hell.

Any ideas?

a little more on the shopping cart thing. I'm having a lot of trouble figuring out which cookies are set where, when, how, and why for zen carts sessions.

I tried to make a redirect based off sessions on a page that had nothing to do with zen cart and just couldent get it working even with my own unique named session.

<?php
session_start();
require_once('inc.functions.php');
$_SESSION['redirected'] = 1 ;

//redirect them now

header('Location: index.php');
?>

none of that worked. session wouldent set or would be over written in zen cart or i have no idea.
