Use hidden, such as:

<input type="hidden" name="step" value="1">

After the form is posted, $_POST['step'] will = 1.

I use this technique all the time so that I can use the same script 
to present different forms based upon which step in the form 
processing the user is on (i.e., step=1, step=2, step=3 and so on).
