Answer 1

With a PHP loop? A very quick example would be:

$letters = array("a", "b", "c", "d", "e", "f", "g", "h");

foreach ($letters as $letter)
{
   // does one of the fields contain input
   if ($_POST[$letter.'posheld']!="" || $_POST[$letter.'comtel']!="" || $_POST[$letter.'immhead']!="" || $_POST[$letter.'from']!="" || $_POST[$letter.'to']!="") 
   {
      // process record
   }
}
