Exlude payment method

Recommended Posts

In my shop people have the option to pay using the invoice that is shipped with the product. We find this a user friendly way to pay and easy for the customers. No need to sign-up with PayPal, Way2Pay or any other payment method.

Unfortunately the downsite is that there are always people that DON'T pay.

Bummer...now we have to take the nessecary steps to get our money.

We would like to reduce the risk of loosing big amounts of money by not having the payment method available if the items in the shopping cart exceed say more than 50 euro's.

The problem is....I have no clue how :D

 

I have been looking at the payment module and the are all sorts of checks that look if the module is enabled, zone is right, etc, etc. I guess it must not be so difficult to get this extra check, but like I said...if have no clue how.

 

Would someone know how?

 

Thanks in advance.

// disable the module if the order only contains virtual products
    if ($this->enabled == true) {
      if ($order->content_type == 'virtual') {
        $this->enabled = false;
      }
    }

 

I imagine you would want to add something like...

 

// disable the module if the order's dollar value is over $50.00
    if ($this->enabled == true) {
      if ($order_totals > '50.00') {
        $this->enabled = false;
      }
    }

 

Of course, this is just a quick one off, but I imagine it would work something like that with a little troubleshooting...

ps. no warranties are given with the above code .... use at your discreation ;)

The question is not, 'to code, or not to code'

the question is, 'if we do not code, are we really alive?'

ps. no warranties are given with the above code .... use at your discreation ;)

// disable the module if the order's dollar value is over $250.00
   if ($this->enabled == true) {
     if ($order->info['total'] > '250') {
       $this->enabled = false;
     }
   }

 

Found it, tested it, and now using it for my stormpay module.... ;)

:D :D :D

Great !!!

I appriciate it. Thanks for your time.

This will reduce our risk a lot and force people to pay in advance when larger amounts of money are involved.

 

Thanks!
