Html multipe输入类型颜色，将所选颜色插入数据库

I am using the input type color to select the color to customize my site. I am inserting the selected color to database and retrieve it back and apply to the site this is working nice for a single input type color. For now i have an input type color and a button with this when i select the color and click the button then , the area name and color inserted to database like area name = footer and color = #CCC, now my problem is that i want to do this for all the content,header,left sidebar and right sidebar.

Any help would be appreciated. thanks in advance.I am using the input type color to select the c
