Vendor Rating System

Type: Full Script

Category: Voting

Description: We originally wrote this “voting system” to rate Vendors in a banner-sharing system on a scale from one to ten.

You’ll need to add an SQL database called “vendors” with a Drop Table called “RECORDS” having these fields (in order):
ID = int autoincrement primary key
Name = varchar (32)
Description = varchar(255)
VoteCount = int(11)
VoteTotal = int(11)

Now create some records in the database… of course it doesn’t have to be “vendors”, use anything you want to rate and track on a scale from one to ten.

Remeber to configure the script with your correct login and password,

This script is really stripped down, so you can see how it works… but it is fully functional. Perhaps you will want to add a “Thank You” screen after a user has completed voting, right now it simply retabulates and shows the new totals. If you have many items to be voted on, you may want to add a “next” and “prior” button setup. Finally, you’ll almost certainly want to pretty it up to match your web page scheme.
