I have an idea for a site I'd like to create. It's all in my head, and very functional, but I know nothing about programming PHP. I want to lay out the site idea, and I'm looking for feedback on difficulty level and if its something I can do with enough research from the internet to get it done. Basically i want to create a site with a login. Once the user logs in, they have options to do a few things. The main task is a customer order acknowledgement app. The user would come to this page and would be able to choose what kind of acknowledgement they are going to send (i.e. Receipt of Order, Order shipping, Order cancellation) and then go to a new page and within the page would have a series of fields to answer (customer info, email addy, ship-to info, shipping charges, tracking #, etc). Once they answered the fields and hit submit, it would then email the customer and thank them for the order and provide shipping info. I'd like for the email to look professional, utilizing logos, etc. How difficult would it be to accomplish this? I've been reading about the mail () function.. seems do'able..
