Limiting max-purchase amount for Credit Card Payments?

Hello Everybody. I am hoping that I can find some help, as I have not been able to find the answers just yet.

I have a website, https://www.finalsupport.org. I am using ZenCart 1.3.8a.

I am curious if there is a way to limit the amount that a credit card can purchase. Some of the items on the site are expensive, a few thousand dollars.

I want to set a limit of $5000 to credit card payments. While I am processing offline, I would like any order total over $5000 to only be able to use the Bank Draft module instead (Which is actually the accept echecks module).

Is there a way to do this? Does anyone know of a Mod to do this? If so, I'd appreciate any insight.

Thank!

That will require a modification for your payment module for your credit card processor.

I "tweaked" Andrew Berezin's "Minimum Value in Cart" module, to make it a "Maximum Value in Cart" module:

There may be a way of inserting a CONDITIONAL STATEMENT that will make this module work only for certain payment modules.

PM Andrew and see if he's able to advise...

The modules are controlled based on the:
$this->enabled

you could add an IF to that and set it to false when the order is >= 5000 and it would not show by setting the $this->enabled to false ...
