required fields in php - how do I?

rskuse · Dec 17, 2002

I use the following mail command to receive form data in my inbox:

<?php

$msg .= "Name:\t\t$_POST[name]\n";
$msg .= "E-Mail:\t$_POST\n";
$msg .= "Company:\t$_POST[company]\n";
$msg .= "Telephone:\t$_POST[telephone]\n";
$msg .= "Address:\t$_POST[address]\n";
$msg .= "Comments:\t$_POST[comments]\n";

$recipient = "me@myaddress.co.uk";
$subject = "Contact Form";

$mailheaders = "From: My Web Site <> \n";
$mailheaders .= "Reply To: $_POST[email]\n\n";

mail($recipient, $subject, $msg, $mailheaders);

echo "<HTML><HEAD><TITLE>Form Sent!</TITLE></HEAD><BODY>";
echo "<H1 align=center>Thank You, $_POST[name]</H1>";
echo "<P align=center>We will contact you shortly</P>";
echo "</BODY></HTML>";

?>

Can anyone tell me how I make the name and e-mail fields, required fields?

Thanks in advance for your help

I will write a script that outputs a form which submits the data back to that same script.

The meat of the script is usually of the form:

if (array_key_exists('some_form_field', $_POST))
{
if (check_for_valid_input() == TRUE)
{
send_email();
show_user_confirmation();
}
else
{
show_form_with_userdata_and_errors();
}
}
else
{
show_blank_form();
}
