I have created a custom payment method that customer can choose that after order
but after order is placed and the payment was unsuccessful there is no payment button on the sales/order/view/order_id/104
How to add the ability to this order_id view page so that if the payment was unsuccessful by adding the payment button the person could be able to pay the order invoice
I know that there are two options one is in the theme and the other is overriding the module
is there any other better way than those
Go to Solution.
I found the best solution
in case there is an extension which will add some additional functionality it requires to override the view/layout files which in this case is sales_order_view
