How to access hook payment if module is not payment module

[NishantVadgama]

hello

I am developing a module. and I want to display some data with cart summary just above payment methods displays before payment done (last step of checkout). I have register hook "displayPayment" but my template file not display. so is there any way to display on that page using any other hook..?

can you show us the hookPayment function that you have created?

 

you should also know that the displayPayment is for showing a payment method that the customer can choose, it was not meant for showing information above the payment section.  For that you should look at using topPayment hook instead
