Beginners Help, Submission Data

Question

I am ABSOLUTELY NEW to coldfusion. But I believe I have a
good head on my soldiers and the "Building Your First Database
Website" tutorial gave me a lot to work on. So using dreamweaver 8
I am trying to basically make a system where you can look up and
edit customer data, products, employees, and invoices. I am now
getting to the hard part which is actually making the invoice
portion of the site. I drew out on paper an idea on how I would
like it to look. Basically I would like then to type in a product
ID and have all the other fields about the product fill in. Then
they would type in a quantity number and then it would times the
price and give a total. I HAVE NO IDEA on how to even have it
submit and retrieve information based on what the user might input.
I am not 100% sure what information you all would need/like but it
is all located on our webserver.

The webserver is not the testing environment so I do not have our
database setup with coldfusion on the webserver. Let me know what
information you all need because I am very sure that I have been
very broad and not detailed enough.

Answer 1

I re read what I said and realized how confusing it
sounds..... Let me re phrase this to something basic, also I was
hoping someone could post some sample code on how to do this.
I have a table called Invoices and a table called Products
I wanted to have a text field called Quantity (not currently
in any of the tables but user enters value) and a text field called
Product_ID (user enters value, primary key under Products) and the
user click like a submit button OR it automatically pulls up the
rest of the information. I wanted it to pull up a product name and
price field based upon the user entry in Product_ID.
What perhaps would be some sample code to:
Take the values from the text boxes, put those values into an
sql query, retrieve the values and fill in some text boxes.
Thank you.
