I have Created a VALIDATION CLASS... can plz tell if its the right way of doing it in OOPs. and have i left out any other USEFULL validation process

Seems pretty comprehensive to me. Looks like it should do the job you want it to.

 

Just make sure on any form fields you also set a max length too.
