How to pass error validation message from php to html form

Postby barrington » Wed Jun 12, 2013 4:29 pm

How do I pass error message back and display above the html form....

if($_POST['frmSubmit'] == "Send") {

$email_to = "";
$email_subject = "Contact Form Submissions";

function died($error) {

// your error code can go here
echo "We are very sorry, but there were error(s) found with the form you submitted. ";
echo "These errors appear below.<br /><br />";
echo $error."<br /><br />";
echo "Please go back and fix these errors.<br /><br />";

// validation expected data exists
if(!isset($_POST['name']) ||
!isset($_POST['email']) ||
!isset($_POST['phone']) ||
!isset($_POST['message'])) {
died('We are sorry, but there appears to be a problem with the form you submitted.');

$full_name = $_POST['name']; // required
$email_from = $_POST['email']; // required
$telephone = $_POST['phone']; // not required
$comments = $_POST['message']; // required

$error_message = "";
$string_exp = '/^[a-zA-Z0-9 ]*$/';
if(!preg_match($string_exp,$full_name)) {
$error_message .= "<li>The Name you entered does not appear to be valid.</li>";
$email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/';
if(!preg_match($email_exp,$email_from)) {
$error_message .= "<li>The Email Address you entered does not appear to be valid.</li>";
$string_exp = "/^[A-Za-z .'-]+$/";
if(strlen($comments) < 2) {
$error_message .= "<li>The Message you entered do not appear to be valid.</li><br />";
if(strlen($error_message) > 0) {
$email_message = "Form details below.\n\n";

function clean_string($string) {
$bad = array("content-type","bcc:","to:","cc:","href");
return str_replace($bad,"",$string);

$email_message .= "Name: ".clean_string($full_name)."\n";
$email_message .= "Email: ".clean_string($email_from)."\n";
$email_message .= "Telephone: ".clean_string($telephone)."\n";
$email_message .= "Message: ".clean_string($comments)."\n";

// create email headers
$headers = 'From: '.$email_from."\r\n".
'Reply-To: '.$email_from."\r\n" .
'X-Mailer: PHP/' . phpversion();
@mail($email_to, $email_subject, $email_message, $headers);

Use a session variable and the controller file as shown here: ... ut-errors/

Or you could do this:

Code: Select all

<h2><?php echo (isset($error_message)) ? $error_message : "Contact Page"; ?></h2>

this is considering you don't redirect your error messages and the HTML view code is either in the same file or is included.

Return to “PHP coding => General”
