使用PHP循环？一个非常简单的例子是：
$letters = array("a", "b", "c", "d", "e", "f", "g", "h");
foreach ($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
}
}
