More specifically, .. there would already be 3 form fields on the page
The user would then be able to click on an "add more fields" link/button, .. and every time they click on it, .. another 3 text input fields would be displayed underneath the others. Alternately, .. they'd be able to click on a "delete fields" button/link beside a row of fields to delete that row. The user should be able to add as many additional sets of fields as they want, and to be able to delete any of all of them as needed.
Finally, .. I need to know how to handle these POST values using PHP on the form handler side. Do I need to keep track of how many form elements were added and then loop through them somehow? If so, ... how? Or is it actually a lot simpler than that?
