I am using Joomla 2.5 version. And I am using Virtuemart component for my website.
I have to check that if user is a VIP user then, deduct 10% amount from default virtuemart cart prices.
How can I do this ?
Should I develop virtuemart plugin for this purpose?
I know core file hacking is not better technique to change cart values.
I have some business logic to check that if user is vip or not.
If I have to develop plugin for virtuemart (for this purpose) then how can I do this? I have no idea about plugin development on virtuemart, documentation of virtuemart is very poor also :(
I searched a lot but I did not find anything on google too :(
