Filter WooCommerce orders by payment gateway

Here is how you can filter WooCommerce orders by payment gateway in the WordPress dashboard orders screen using a plugin from SkyVerge.

Add the php file directly or in a folder in the /wp-content/plugins/ directory and then activate the plugin from the WordPress dashboard.

Now you will see a column that allows you to choose a payment gateway and then filter the orders to show only those that have been paid via the gateway.
