Create a unique ID which you use in all steps of your wizard. Save that ID to the database upon the initial saving of your form. Forward this ID to the next steps using a input type="hidden".
When saving a step, first try to match the ID and, if you find it int the database, perform an update instead of an insert.

To avoid the "do you want to resend post data", perform each wizard step in two CodeIgniter controller actions:

• SaveStep5(POST: form instance ID + other "wizards step 5" inputs): looks up the form instance ID in the database and performs insert/update commands; redirects to LoadStep6 and passes the form instance ID in a GET parameter;
• LoadStep6(GET: form instance ID); looks up the form instance in the database, if the instance is not found: error handling if the instance is found, renders the input form for "step 6"
