Need help with logic

[tryin_to_learn]

I'm doing some forms for a conference. They actually have 5 different ways you can register, each of which needs a different form -- a pre-conference, an individual registration, family registration, youth registration, etc. Most people who register will want to register some mixture of the above, like 1 individual, 1 family, 2 youth, etc. I'm wanting to collect data upfront to see what kind and how many of each form they need and then dynamically generate the forms they need in order -- like, for the above example, I'd first show them an individual form, then when they finish with that, I show them a family form, etc. I'm having trouble thinking through the logic of how to program that.

I started off with this (the 5 arguments are for each of the forms; the value of each is the number of that particular form that's needed):

function showForms($ind, $fam, $ya, $bs, $pre) {
	if($ind != ""){
		showIndForm();
		}
}

function showIndForm() {
	echo "<p>The individual form will go here.</p>";
	}		

All of that works, but that's when I realized that I needed help with the logic. Like, what if someone wants 2 ind forms, no fam forms, 1 ya form. Or maybe they want no ind forms but 2 bs forms. There are lots of possibilities and the way I had started out isn't going to cut it. Can someone get me started?

When they submit the first form, which tells you how many of what type of registration form they want, create an array in a session variable that has all the forms that they want. So, if they wanted two ind, 1 fam, 1 youth, then you would have an array like this:

array('ind','ind','fam','youth');

Then go to another page which gets the first entry in the array and provides that type of form. Once that form is created, remove that entry from the array, so that you have n-1 entries. Once they submit that form, check to see if the array is empty: if it is, they're done, if it isn't, then create another form for the 'new' first entry in the array. Keep repeating until done.

Thanks, that's helpful.
