Self-managing web approach

I'm creating a self-managing web in Code-igniter. The idea is that each section of the web can add content from one or several forms, the doubt: The sections have html objects that differ among their attributes, someone will have developed something similar, what I would like to do is a table with an XML or JSON column where I save the attributes of the serialized objects, but I would not like to start if my focus is not the Right
