Question

I have a site that allows users to vote on images. Each image has a unique id number. For voting restriction purposes, I’d like to keep track of what each user has liked. How would I go about setting up a row in the USERS table that holds all the different id numbers of the images liked by this particular user?

Answer 1

You should not have all this information in your users table. I persume that you have one table with all your images and one with all your users. Create a table called “user_image_like” for example. And store “user_id” and “image_id”. When the user presses like on the image your script will add “user_id” and “image_id” to the table.

When you wan’t to see all images liked by a user you can easly get this by a simple sql query.
