Price dependent payment module

October 7, 2004

Hi, I'm hacking together a futurepay module for worldpay. I've got it working fine but I now need it only to be a valid payent option if the order total is above a certian amount.

Can anybody help me please? :D

Obviously somewhere I need to run the check 'is the order total above XXX'

but...

Do I do this on the bit of the system that decides what payment modules are installed or do I do this in the payment module itself?

i.e. only show this module as an option if order is greater than XXX

I'd be really really grateful if anyone could give me the answer to this one... and a bit of code is always nice! thanks a lot ;)

Can you let me know how you did this? is your hacking contri ready? Maybe you can share the code with me?

I need to set this up too :blink:

I yust got email from who sent my 3 files he modified for the futurepay but he did not work with product atributes i think...

Your futurepay works like the paysystems ?

under your Admin, Product Attributes add a Product Option called Billing Method, two Option Values one Yearly and one Monthly

Hi everyone

I've finished by FuturePay hack and it works great. I've been asked to post the code so here goes. I'm sorry if this is a little clumsy, but I took the original WorldPay module and just added a few extra variables. This isn't an official contribution but hopefully somebody else will make it one.

I need a WorldPay payment module that took the total, divided it by 4 and then took 4 equal monthly instalments instead of all in one go. WorldPay's FuturePay does this really well, it's just a question of passing the right variables through to worldpay's system. I simply asked WorldPay the exact set up of these variables to achieve what I wanted and they kindly emailed them to me. I then forced these variables into this payment module. Please note these are my variables and work for what I want. You will have to tweak these numbers to get them to work the way you want them to.

My biggest problem was to seperate the module from the normal WorldPay module whiich I wanted to run independently from this one.

i.e.

Pay by WorldPay (full amount)

Pay by WorldPay (in 4 instalments)

I achieved this by taking Graeme Conkie's original module, copying it, and calling the new one worldpay1.php. I then hacked around with it :-)

This is my modified module...

This needs to be saved in includes/modules/payment.

You also need a slightly modifies language file. Mine is...

I hope this works for everyone as well as it has done for me :-)

Thank you,

So you have:

By 4 Monthly Credit Card Payment Instalments

and

normal cc payment by Worldpay

so you do not work with

"Admin, Product Attributes add a Product Option called Billing Method, two Option Values one Yearly and one Monthly."

the paysystems contribution uses this one: http://www.oscommerce.com/community/contri...arch,paysystems

look at the attached picture what I mean with product atributes

November 24, 2004

No I don't use that module.

I have pay in full (worldpay), or pay in 4 instalments (also worldpay).

I don't have to do any of the future billing, worldpay do it through their futurepay agreement with the customer. I just get the money in monthly instalments.

Thank you,
