Restricted access to Payment Modules

[gdhgdh]

Hi :)

Is the following possible (without lots of if..then..else PHP code) ?

I'm in the UK and want to take card payments using Nochex whenever possible. The Nochex APC module works great and the checkout system procedure looks professional.

Alas, Nochex have a limit of £100 per transaction, and is only available to UK buyers unless I open a Merchant account (which at £50 is beyond my means until the shop starts to pay for itself!).

So, whilst I'm happy to keep PayPal as an option for all buyers, I need Nochex to disappear from the payment types if the buyer is non-UK or the cart value is more than £100.

Any ideas? :D

Cheers,
Gavin.

Two things to do:

1. Create a Zone Definition for UK only. Be sure to add UK-AllZones to its details.
Edit your nochex payment module settings via the admin->modules page, and select your UK zone in the Payment Zone field to restrict the module to only work if the customers' address matches the defined zone.

2. Edit the PHP file for your nochex payment module.
In it you'll find a line that says:

      if ($check_flag == false) {

Add the line shown below above that line, so that it looks like this:

      if ($_SESSION['currency'] == 'GBP' && $currencies->value($_SESSION['cart']->total, true, 'GBP') > 100 ) $check_flag = false;
      if ($check_flag == false) {

This should restrict it so that if the cart's value is greater than 100 GBP, the module will be disabled.

Wow you're a star - I'll be sure to give that a go, thanks!

I did a bunch of these kind of things a few years back with osCommerce (can't even remember its old name now) but I've long forgotten it all - thanks for the leg-up :)

Lovely job.

For the purposes of reference, the only thing that needed to be added here was to amend the start of the function thusly:

function update_status() {
global $order, $db, $currencies;

i.e. adding $currencies, else you get a PHP non-member object error

Thanks again :)

Yes - correct - good catch.

Heh, almost there - found an edge case... it's only checking the value of the cart contents, not including shipping.. so if the cart is £99 and shipping pushes it over 100, Nochex payment will fail...

If $currencies->value($_SESSION['cart']->total is purely the cart contents minus shipping, how do I get the shipping value?
