Hook to add user question during checkout

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.6

I'm about to develop a payment plugin, where the user is required to select a bank, before the payment transaction can be created, I.e. the name of the user's bank must be known before communicating to Payment Service Provider. I'm looking for a hook where to inject the code to ask the user for these details, but couldn't find any.

I'm about to alter the code in views/checkout/tmpl/payment.php to look for a file in the corresponding payment plug-in dir, that contains the additional user interaction.

Do you have any thoughts on this? Is there an alternative?

Thanks and regards, Paul van Haren

Thank you. This is exactly what I was hoping for. I'm glad I asked.

Thanks again, Paul
