Some Advice/Help Please

[Mighty Mike]

Hi

 

Hope i can get some advice/help on how i can go about and implement something on my site.

 

What i would like is when a customer goes to the create_account page enters all their details and also selects a membership level, once they hit submit it would redirect them to my secure payment provider (Protx) enter their card details and return back to my site with the account setup for them.

 

Sounds easy, but i am not too sure where to start.

 

On the create account page i would like to have three membership levels/products and the customer would simply select the one they want (Radio Button?).

 

Would i need to rip out the code from other pages like shopping_cart etc.

 

Any advice on how to do this greatly appreciated

 

Thanks

 

Mike
