I am fairly new to php and mysql. I know a little more Php and am just starting to work with Msql. I am constructing a website where I will be selling items on. I also want to have customers signup and be able to sell their items in particul categories of their choice with an image and description and price amount. I have a book that takes me step by step on creating a login and ecommerce site, however, I can't find any information regarding customer uploading and selling to my site as well. I guess similar to like let's say ebay or something , however, it's not an auction. Just a store.

Can anyone point me in the right direction for maybe a good book or websites, etc. any help would be appreciate.

Thanks!
