Fix cart price rules by Payment Method in Magento 2

If you try to create a new discount rule in Magento 2, you'll see a condition called "Payment Method" there. This condition means that the discount will be applied in case a customer selects a certain payment method. But actually, this rule will not work due to a small omission in Magento 2 checkout. The module in the repo fixes the issue.

Installation

via Composer (recommended)

Run the following command from your Mangento root folder:

   composer require magestyapps/magento2-fix-discount-rules 

Manually

• Create folder 'app/code/MagestyApps/FixRules/' in you Magento setup

• Extract the repo files to the folder

• Open console (terminal)

• In the console (terminal) navigate to your magento root folder:

  cd /path/to/your/magento
  

• Install the new module using the command below:

  php bin/magento setup:upgrade
