osQuantum Development Forums _ Contributions / Add-Ons _ Lay-by payment module

Posted by: Maxxxie Aug 24 2007, 11:47 PM

Hi everyone,

I'd like to have a payment module that works along the lines of a lay-by system. The customer is presented with a total, then presented with a value of 10% which is the deposit they must pay for the order to be acted upon. It is a requirement that the customer receive a receipt stating the terms and conditions of the layby arrangement. My intention is to use email to do this.

To this end, I've butchered the http://www.oscommerce.com/community/contributions,1777 and combined it with another payment module (Australian bank deposits) to suit my needs. At checkout, the customer is presented with the terms and conditions and the 10% deposit value they must put down. No worries. But I can't seem to get the deposit value to go into the order confirmation email. The best I can seem to do is to derive 10% of the cart total excluding shipping. But I want to show 10% of the total, not the subtotal.

Here's the code I've played with so far (complete with inept failed attempts at fixing the email problem):

I'm struggling with the code at around line 59 (trying to define $EMAIL_LAYBY12). My guess is that I'm just interrogating the wrong variable, but I've no idea which one I should touch. I'm pretty sure I'm grasping at straws with the $_SESSION variable.

I'd appreciate any help!

Cheers,
Max

This is the first time I've looked at this, but if you want the 10% deposit amount to show in the email then you need to use an echo command.

Thanks for getting back to me, Vger. Which variable would I interrogate to get the 10% value though?
