Multi step form submission

[eluser]Ravi Bakraniya[/eluser]
I am using a registration page having four steps and i am having a field called "Username" in first step and i don't want user to repeat the username, all the data should be added to the database in the fourth step.

i have used session right now, and it works fine but the problem i am facing is about a lot of queries.

i have used keep_flashdata() to keep the session alive, but it keeps the session only for the next server request so i have to repeat the code "keep_flashdata()" in every step.

i am getting almost 100 queries fired at step3 while i have just 10 fields at step1 and i have written "keep_flashdata()" at step 2 and step3.

as i know, i am getting these 100 queries because of this reason.

I am very new to CI, please help

Use set_userdata() not set_flashdata so you can bring around all the data you need:

thanks for reply,
it stores the fields to database by using set_userdata() and i don't want to storte.
is there any other way?

This is not true, the session is stored to a cookie. The session can be stored to a database only if you create a ci_sessions table (or whatever you set on the config.php file), but the custom data is always saved in the cookie. Bye
