Multiple Item Form Validation

[Anon]

I am new to PHP and am trying to write a form validation script that will check multiple fields to make sure they are not blank. I know how to check a single field with if (name) {
etc...
can I add all of the required fields in the parenthesis? and how do I designate which fields they need to correct if one is blank?
thanks for any help

If they all need have a value then you can do this:

<?

while (list($key,$val) = each($HTTP_POST_VARS)) {
if (trim($val) == "") {
print "You must enter a value for $key. Please click the back button and try again.";
die;
}
}

?>
