I've found similar questions, but have been unable to tie them into my example. I am very new to PHP and completely self teaching.
At present I have a form for entering a new customer. In that form I want the user to be able to select an existing DB item (business) and insert that BusinessID into the CUSTOMER table. My problem is that I can GET the BusinessID, but then I can't POST that same ID with the other field inputs. Code below
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">

So being able to insert the value from my drop down is the main issue. Additionally, I'm sure there is unnecessary / incorrect code in what I posted, I've been piecing together examples one at a time.
Thank you for all the help, if I can get this working I can have a functioning basic version of my application
EDIT
I have successfully prepopulated my drop down, and the user then chooses from that list. I want to pass that choice via my INSERT statement. I worry that the two different CONNECTIONS which I establish are part of the reason my INSERT won't recognize $Business
