Feedback form - how can we implement this?

I have 5 persons responsible for sending feedback forms.

I need to later on the process, understand for all of those persons, who as received more filled forms.

There is no login system. The forms will be sent by email.

I'm thinking about creating 5 separate forms, and on each of those, have a hidden field with some id. Based on that, when the form data is saved on the database, that id will be saved as well.

A simple count() may return the data needed.

HOWEVER, I do think that perhaps, there is a better, simpler, logical approach to grab this information ?

I believe that having 5 different forms where only a hidden field is the difference, is a dummy idea.

Update: Can we fill in that hidden field with different data based on what person has sent the form ? I'm not seeing if this is possible.

Or, another idea, can we, have a .htaccess that will popup a usern开发者_运维问答ame / password window, and based on that credentials, display a form with an hidden field associated with that (username / password) credentials ?

Any other ideas ?

And why cannot those persons fill in their nickname/login/identificator into a separate field?

Or do You want them not to know about counting their responses...?
