Navigation via Bullets and check box combinations

I have a form:

bullets:
product one
product two
product three
product four

check boxes:
w/ option one
w/ option two

This creates 16 posibilities that go to 16 different links.

How can I code this in PHP or javascript?

 

To help you search, what you are calling bullets are actually called "radio buttons".

 

Thanks, SP. I still am having trouble finding the combination of using both radio buttons and check boxes. Any ideas?

 

I did it in javascript:

<script>
 function navnav(){
 var pl = {1:[30623,30629,30626,30632], 
           2:[30635,30641,30638,30644], 
           3:[30647,30653,30650,30656],
           4:[30659,30665,30662,30668]};

 var i = 0 ;

 jQuery('input[@type=checkbox]').each(
     function() {
         if( this.checked ) {
         i = i + parseInt(this.value);
         }
     }
 );
               
 navnav_id = pl[jQuery('input[@name=prd1]:checked').val()][i]; 

 var url = 'https://secure.thesite.com/orderpage.aspx?products='+navnav_id;

 window.open(url, '_self'); 

 }
</script>

Code (markup):

Here is the form:

<form method="POST" name="orderForm" >
<input type="radio" name="prd1" value="1" checked />
<input type="radio" name="prd1" value="2" />
<input type="radio" name="prd1" value="3" />
<input type="radio" name="prd1" value="4" />
<input type="checkbox" name="checkbox_item[]" value="1" checked />
<input type="checkbox" name="checkbox_item[]" value="2" checked />
<input type="image" onClick="navnav(); return false;" src="images/continue.gif" border="0" />
</form>
