dynamic form validation and sql

[mahalleday]

I am trying to create a PHP application that will allow users to create custom HTML forms.  I have finished the code that adds the  from fields to a database and the generate the from based on what is the database tables.  What I need to do know if validate the inputs and store the form data in a mysql database table.  Easy enough o do with a static form but because there can be any number and combination of inputs in these form I am at a lose as to how to write both a dynamic validation script/class as well as a dynamic mysql query statement.

 

If any one has done this before or could point me to a tutorial to show me how to this that would be very much appreciated.

 

I will post some code once I have made my first attempt at it right now I have no idea where to even begin with it.
