</form>
Jquery
// Get the messages div.
var formMessages = $('#form-messages');
// Set up an event listener for the contact form.
$('form').submit(function (event) {
// Stop the browser from submitting the form.
event.preventDefault();
// Serialize the form data.
var formData = $('form').serialize();
// Submit the form using AJAX.
$.ajax({
type: 'POST',
url: 'contact_form.php',
data: formData
})
.done(function (response) {
$(formMessages).text("Your form has been send..");
// Set the message text.
$(formMessages).text(response);
// Clear the form.
$('#name').val('');
$('#email').val('');
})
.fail(function (data) {
$(formMessages).text("Oops! An error occured and your message could not be sent");
// Set the message text.
if (data.responseText !== '') {
$(formMessages).text(data.responseText);
} else {
$(formMessages).text('Oops! An error occured and your message could not be sent.');
}
});
});
Php
<?php
// Only process POST reqeusts.
if ($_SERVER["REQUEST_METHOD"] == "POST") {
// Get the form fields and remove whitespace.
$name = strip_tags(trim($_POST["name"]));
$name = str_replace(array("\r","\n"),array(" "," "),$name);
$email = filter_var(trim($_POST["email"]), FILTER_SANITIZE_EMAIL);
// Check that data was sent to the mailer.
if ( empty($name)) {
// Set a 400 (bad request) response code and exit.
http_response_code(400);
echo "Oops! Dogodio se problem za vašim zahtjevom. Molimo pokušajte opet.";
exit;
}
// Set the recipient email address.
// FIXME: Update this to your desired email address.
$recipient = "email#hotmail.com";
// Set the email subject.
$subject = "Web contact from $name";
// Build the email content.
$email_content = "Person: $name\n";
$email_content = "Email: $email\n";
// Build the email headers.
$email_headers = "From: $name <$email>";
// Send the email.
if (mail($recipient, $subject, $email_content, $email_headers)) {
// Set a 200 (okay) response code.
http_response_code(200);
echo "Thank You! Your message has been sent.";
} else {
// Set a 500 (internal server error) response code.
http_response_code(500);
echo "Oops! Došlo je do pogreške, nismo uspjeli poslati vašu poruku.";
}
} else {
// Not a POST request, set a 403 (forbidden) response code.
http_response_code(403);
echo "Dogodio se problem za vašim zahtjevom. Molimo pokušajte opet.";
}
?>
And this is error i get:
Fatal error: Call to undefined function http_response_code() in /home2/speanut/public_html/freeforexreport.com/contact_form.php on line 35

Seems like your PHP Version is below 5.4. The http_response_code() function was introduced in PHP 5.4.
I would advice you to update for PHP 5.4 or higher. If you can not do that, you can use following compatibility code:
// For 4.3.0 <= PHP <= 5.4.0
if (!function_exists('http_response_code'))
{
function http_response_code($newcode = NULL)
{
static $code = 200;
if($newcode !== NULL)
{
header('X-PHP-Response-Code: '.$newcode, true, $newcode);
if(!headers_sent())
$code = $newcode;
}
return $code;
}
}
