This is a complete working example.
<?php
// this is for troubleshooting errors
// set the 1 to 0 to turn off (must set to 0 when in production mode or when you run this live
error_reporting(E_ALL);
ini_set('display_errors', '1');
?><?php
if(isset($_POST['email'])) {
$email_to = $_POST['email'];
$email_subject = "E-mail from website visitor.";
// try adding a useful/relevent message to errors output to users
function died($error) {
echo "We are very sorry, but there were error(s) found with the form you submitted:\n\t ";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";
die();
}
// validation expected data exists
// since all post are submit, check if they are empty or equal to an empty string
if(isset($_POST['email'])){
if($_POST['email'] == "" || $_POST['first_name'] == "" || $_POST['last_name'] == "" || $_POST['telephone'] == "" || $_POST['comments'] == ""){
