How can I get only the selected inputs to be processed in multiple forms?
<p>How can I get only the selected inputs to be processed in multiple forms? <code>isset()</code>?... I want "shoppers" to choose which quantities of each "style" they want and click submit.

 They are then be sent to the confirmation page and will email that page. I will have many item styles with up to 6 sizes each. I have each item style in a separate form currently(and it submits fine). 
I tried to use only 1 form for submitting multiple styles, but that didn't work because I am using the "Required" attribute. 
When I submit only 1 style, It shows "Required" for any fields that are not selected..(When using single form approach)
Submitting only 1 form is great with me! Thanks!  </p>
