php - How to continue a Transaction on multiple pages -

i have 3 html forms on 3 different php pages used insert data in 3 different tables.

current process follows:

• user fills first form & click on "next" (data inserted in 1st table in database)
• user fills second form & click "next" (data stored in 2nd table in database)
• user fills third form & click "finish" (data stored in 3rd table in database)

i want:

commit must issued in case when user fills 3 forms & click finish. if user quits/exits on stage before filling 3 forms, data stored in tables should roll-backed.

can use laravel db::transaction or have other option? please give suggestion.

actually in each steps user can add multiple records in 1 table. example on 3rd step user can add many records in subjects table wants. use following code save these multiple records in table subjects:

for($i=1; $i<=input::get('total_subjects'); $i++){     if(input::get('sub_'.$i) != null){     $sd = new subject;     $sd->class_detail_id = input::get('class_detail_id');     $sd->subject_id = input::get('sub_'.$i);     $sd->status = 'active';     $sd->save(); } 

now problem is: how possible store references models of subject ? solution comes mind make transaction , commit after 3rd step otherwise transaction roll-backed.

why not put form data temp session variable , after completing step 3 insert data session database?

why use method instead?

1) there no trash in database.
2) session auto-cleans after user leaves webpage (willingly or accident).
3) can move freely between steps , info auto-filled or return.
4) 1 connection database - faster website.
5) enables use transactions.
