Hi guys, I've been using this code to try and get image paths to upload to a database and store the image in a file called "upload/" but it doesnt seem to be working. I am also using two tables in my database and need to add into the script the user session id (user_id primary) from the current page and store it into the (user_id foreign) for the cycles tables.

 

thanks
