Edit Order: Payment Method Req'd with Free Checkout [Solved]

OC: 2.3.0.2

When I try to Edit Order in Admin, I cannot complete changes because of error: "Warning: Payment method required!"

The order was placed using "Free Checkout", when customer used a coupon that causes Total to be $0. So when I try to edit that order in Admin, on step 5, the Payment Method has "Please Select" and "PayPal". The only way I can commit changes is if I switch the Payment Method to PayPal.

Free Checkout is not available in list of Payment methods for me to choose from. Additionally, the Shipping method is disabled (but required). I have "applied" the coupon during edit, which changes Total to $0, but "Free Checkout" still does not become available for Payment Method.

Any suggestions on how to allow editing an order placed via Free Checkout without changing Payment Method to PayPal (in my case)? Possibly the Payment method should not be required?

Thank you for any assistance or ideas.

It seems like an issue. As free checkout should come.
Can you try this one thing. Click on apply coupon button. And then go back to step 4. And then come back on step 5. And then see if payments are updated.

If that doesn't work, you could try this edit, which should enable Free Checkout if it's being used in the admin panel order editor, regardless of the order total:

After applying the Coupon on Step 5, then go back to Step 4 and proceed to step 5 makes "Free Checkout" appear as the Payment Method. This indeed resolves the issue. Thank you!

Code: Select all

IN:
/catalog/model/extension/payment/free_checkout.php

REPLACE:
if ($status) {

WITH:
if ($status || isset($this->session->data['api_id'])) {

This solution works as well. Now I have 2 great solutions! The solution by imdevlper18 does not require any code changes. Simply apply the coupon, step back, then forward again. Personally I will use Johnathan's solution because IMO, "Free Checkout" should always be a choice, regardless of using a Coupon or not.

Thanks again. My research led me to a similar issue: Opencart Coupon Code Cancels Orders (#3657) in OpenCart GitHub repository. Although only semi-related, it may help others that are having issues with Orders placed with a Coupon.
