hi,

you can have an array defined which will have the fieldnames as defined
in the form. then have a function say validateFields() in PHP which
will loop through the array and check the value.

if the value is null then your validateFields() will keep adding the
field label and after looping through the array, it will have the full
error message which will be returned. your PHP should check if the
value returned is 1 or not. If 1, then validation was successful
otherwise it will stop further processing and print the returned error
message.

Example:
==============

$fieldsToValidate = array ('field1' => 'field1 Label', 'field2' =>
'field2 Label');

function validateFields()
{
$err = "<font color='#ff0000'>Following fields cannot be left
blank:<ul>";
$errCount = 0;
foreach ($fieldsToValidate as $key => $value)
{
if ($_POST[$key] == "")
{
$err .= "<li>" . $value . "</li>";
$errCount++;
}
}
$err .= "</ul><font>";

if ($errCount > 0)
return $err;
else
return true;
}

Take the returned value and do the rest of processing.

Hope this helps.

Thanks and God Bless!!
