handling a dual function form
<p>I have a a form on my site that handles employee details.</p>

<p>If there are no associated values in the DB then the form function as a create details form.</p>

<p>If there are associated values in the DB then the form is populated with those values and the form functions as a update/edit form.</p>

<p>Assuming the form is functioning in it's update/edit mode.</p>

<p>Is the best manner to handle the update to delete all the existing values then create new ones?</p>

<p>I am fairly sure it will not matter that the unique ids are being constantly changed.</p>
