Features

• Adds an offline “MMG Offline Payment” method for both classic and block-based checkouts.
• Requires shoppers to enter their MMG confirmation number before an order can be placed.
• Stores the confirmation number on the order and displays it on the thank-you page, customer emails, and the WooCommerce admin order screen.
• Places new orders on hold so you can confirm the MMG transfer before fulfilling.

Requirements

• WordPress 6.5+
• WooCommerce 8.3+ (for Checkout Block support)
• PHP 7.4+

Installation

1. Download or clone this repository into wp-content/plugins/mmg-woocommerce-gateway.
2. From the WordPress admin, activate MMG Payment Gateway for WooCommerce.
3. Navigate to WooCommerce → Settings → Payments.
4. Enable MMG Offline Payment and adjust the title, description, and instructions to match your MMG account details.
5. Save. The gateway will now appear at checkout and enforce the confirmation-number requirement.

Usage

1. Customers choose MMG Offline Payment at checkout and provide their MMG confirmation number.
2. Upon submission, the order is created with status On hold, and the confirmation number is saved in order meta.
3. You verify the MMG transfer, fulfil the order, and optionally change its status.

Frequently Asked Questions

Does this gateway work with the Checkout Block?

Yes. The plugin registers a WooCommerce Blocks integration so the confirmation number field appears in block-based checkout.

What happens after a customer submits an order?

Orders stay On hold, and the MMG confirmation number is stored on the order, thank-you page, transactional emails, and in the WooCommerce admin.

Can I change the instructions or add my MMG account details?

Absolutely edit the Description and Instructions fields under WooCommerce → Settings → Payments → MMG Offline Payment.

Is the confirmation number required?

Yes. Customers cannot complete checkout without providing the number, and both classic and block checkouts enforce this.
