Also included..
A solution for setting a minimum and maximum perimeter (posted a few posts down)

Difficulty: Easy
Time: 5 Minutes
Version used when writing this tutorial: 1.5.1.3

Presently, the installed payment modules have an option to set a 'minimum' amount required before a payment option becomes available. However, another very useful option is the ability to change this so that a payment option is disabled in the event that an order reaches a certain amount.

This change can easily be made on a per-payment option basis...

To make the change simply decide which payment option(s) you want to set limits for..

We will be making 2 file edits for each payment option; 1 configuration edit and 1 language file edit.

-----

Please note: Although these are simple edits, it's always best to create back-up copies of a file before you edit it in case you make an error editing the file, or if some other issue arises. It's as simple as dropping the original files into a separate temporary folder on your desktop. Be sure to note the directories of those files, since many file names are the same and can be accidentally used to overwrite a completely different file.

-----

Edit #1 - Find the model file which determines the limitation rules..

Open the model file for your payment option under the folder:
catalog/model/payment/

The file name will look something like: my_payment_option_name.php

Search for the line of code that looks like this:

Code: Select all: if ($this->config->get('my_payment_option_name') > $total) {

And simply change 1 character (the greater than or less than symbol from > to <):

Your update will now look like:

Code: Select all: if ($this->config->get(my_payment_option_name') < $total) {

-----

Edit #2 - Change the language in your admin panel so you know what the setting does..

Open the language file for your payment option under:
admin/language/english/payment/

Again the file name will look something like: my_payment_option_name.php

Search for:

Code: Select all: $_['entry_total']

To the right you can change the text.

The default will read:

Code: Select all: Total: The checkout total the order must reach before this payment method becomes active.

So let's change that to something like:

Code: Select all: Maximum Total: Amounts GREATER than this will DISABLE this payment option.

-----

Almost done... Now we just need to apply the setting to the payment option in your admin area.. Simply add the maximum amount you want to set for the payment option.

-----

Now you're all done.

Happy selling

Small adjustment.. Just add lines 3 and 4. catalog/model/payment/-------.php

Code: Select all: if ($this->config->get('my_payment_option_name') < $total) { $status = false; } elseif (1000 > $total) { $status = false;

$1000 is your minimum amount.
The maximum amount is what you have set in the admin CP.

(Note: Be sure the < is pointed the correct way for line 1 in this example)

No prob. Normally I wouldn't bother (since I am not a programmer) but given your name is also karma.. I felt more inclined to figure out a solution lol
