PHP Form Processing with only filled in fields
<p>I have a PHP class which have 8 properties
and a HTML form which have 40 (8*5) textboxes, 8 per object, so a user can enter data for 5 objects at once.</p>

<p>For each set of boxes I want to create an object of the class and save it into my database. If the user for example have filled in 10 boxes (two sets), two objects should be created and saved.</p>
