Added another example of client side custom JS validation w.r.t. particular field. Now you can write your own validation implementation (be it ajax remote checking or complex regex) on each field while adding or editing information in php grid control. For example, certain value must be greater than 100.
If you wish to have back-end PHP level validation, it is also doable using custom on_insert and on_update events.
