Where you currently have "if ($send != "no"){ ... }" you could tack on
something like:
else{
echo $name_err;
echo $email_err;
echo $lastname_err;
}
Once that works, as an improvement, it might make more sense to do like
this:
$message = '';
if ($name == ''){
$message .= "Name must be provided.<BR>\n";
}
if ($email == ''){
$message .= "Email must be provided.<BR>\n";
}
if ($lastname == ''){
$message .= "Last name must be provided.<BR>\n";
}
if (!$message){
# Send the email.
}
else{
echo "<FONT COLOR=FF0000>$message</FONT>\n";
}
By using $message and .= to "tack on" the messages, you can avoid having so
many variables running around confusing you and get the job done just as
well.
