simpleCart IPN Filter

Hi Perch

Thanks for posting.  

We don't support SimpleCart via the forum.

If you'd like to have a more in-depth conversation, you can email us through

Having said that, my first thought is that all transactions created by SimpleCart (ie: orders from your website) will be passing the "custom" field.

And I doubt any transactions you manually created will pass the "custom" field.

Based on this, you could modify SimpleCart to only process orders that include the "custom" field and skip any others.

Note: I recommend you move any customized Simple Cart functions into customCart.php if they are not already there.

You can forward any further questions to

Hi, Ross -

Thanks for this. I never thought about using the custom field. It's quite simple when you think about it.

I'll let you know how I get on.
