My customer wants to offer Puchase Order as the only payment method when total order value exceeds £5000. I have used the Maximum Order module, which displays an error message “Your order value exceeds £5000…” and disables checkout.
How can I now in this instance
1.) disable the other payment options (e.g. sagepay debit/credit card) and leave Purchase Order as the only available payment method when max order amount has been exceeded?
2.) enable the shopping cart in a more clever way other than commenting out the following line:
./includes/classes/observers/class.maximum_order_amount.php
/* zen_redirect(zen_href_link(FILENAME_SHOPPING_CART)); */
Thank you – help much appreciated!

ps. Am originally a C/Java programmer so php is understandable to me but am not very inventive with it yet!
