Exciting new section of my PHP site needs coding (ld)

We have an existing PHP site with a MySQL database. The site is a DIY website kit where customers sign up and basically create their own website. It has all been coded and works well already. We have built the pages for a new section of the site which will allow customers to save certain settings for the layout/colour scheme they have chosen and this is the part that you will be working on. Please read through the detailed instructions in the attached document and feel free to ask any questions. It's mostly just posting data to the database and displaying it back as well. You will be given full ftp and cpanel access to complete the job.
