This is my first post in any forum on this website, and I am fairly new at web programming. I have an online garage sale website http://www.iegaragesale.com and I want to be able to do the following:

1. Have users register with the site
2. Users are able to do the following with their OWN and only their OWN items: post their items, upload pictures to their items, update their items, and delete their items when they sell.

I am using PHP and MySQL right now to populate the database with items. I have an administration page that allows me to post items, upload pictures, update items, and delete items when they sell. But, I want every registered user to have this functionality.

I really don't know what I would need to do this. I know I need a registration script, but I am hesitant to create one just yet because I don't know how to approach the rest of what I want to do.

I apologize for posting this in the general forum, perhaps an admin can redirect this post elsewhere.
