cross check votes on dynamic page

Hello,

I am creating a photo contest that needs to work by tomorrow (fun never ends)
I created a database with a table to store the name, email address, IP, time stamp, pet name, image and another table to store the votes, time stamps, email address, Pet Name and IP.

I will have the user register, upload and vote for their pet, or have a friend vote a pet after they register.

My Question is; The contest allows only one vote per email address. If I have all of the entrants photos with a vote button underneath dynamically populate the page, how can I check to make sure they have not already voted.

I am going to make the page only accessible to registrants.

Any help would be greatly appreciated.

have the login page store the users email address in a session variable when they log in.

If you are using security assist, this is fairly simple, edit the authenticate user server behavior on the login page, on the third step, you can chose columns to store in session variables. add the email address column.


On the page with the vote button, add a recordset to filter the email address column of the votes table on the email address session variable.

use the Dreamweaver Show region if recordset is empty behavior to only show the button if the email address is not found in the recordset.

Jason,
Thanks for the help. Last question (hopefully); When a user votes based on the tables I mentioned above how do I add the votes each image received and show the top 20 on the home page? I am not sure how to set up the recordset.

Thanks again,
Rob

I assume one record is stored for each vote?


SELECT COUNT(idColumn) as numVotes, petName FROM votes GROUP BY petName


GROUP BY petName will return one row for each petName. numVotes will contain the number of votes for each petName. you could add ORDER BY COUNT(idColumn) DESC so that the number of votes is orderred highest to to lowest.

Jason,

Yes, I will have one record per vote. Thanks again, you guys do a great job!
