I have designed a user profile form, a long form which is quite complicated. Before the user can submit and save it, the form needs to be validated.

İşte soru:

When the form is saved into the DB, there are multiple tables involved. Now I would like to introduce a function called "Save Form" which internally doesn't validate the form and just save whatever the user entered.

Bunu nasıl yapabilirim? Gibi potansiyel sorunları vardır:

Q1> How to save temporary data?
Q2> What should I do if the user saves the temporary data 
    without submitting the form and then quit. 
    This feature looks like the Draft feature provided by Gmail.

Teşekkür ederim
