creating multi-step form

Sometimes we need to create multi-step form. But why should we create a multi-step form? and when should we create those? if our form has many fields to fill up, then at times our users may get bored typing texts, so, they may leave the form without submitting the form. But if we have multi-step forms then we can split a long form into several short forms, so, users can submit short group of informations and at any time they can leave the process, but their information upto which they have submitted will be stored at the database, and they can start filling up the form from thereon.

we can use hidden input fields, sessions or store information to databases at each step to carry the information. if we use hidden fields we need to pass a great amount of data at each form submission except the first one, it is not the recommended process. we can store the values into sessions and it will prevent resubmitting the values. We can store the information into databases also.
