Contact Form

Question

Hi! Im having a little trouble with the validation of the contact form... I come out with this "Undefined index" on some lines of the code. Just dont know how to implement the isset to see where the error us coming from.

Could you please help me? I know im kinda lame but im learning how to use php language.

My form is this:

             <div class="col-lg-12">
               <textarea name="message" placeholder="Message*" class="field" cols="40" rows="10"></textarea></p>
              </div>
              <div class="col-lg-12"><input id="send" class="btn btn-default" value="Enviar" type="submit" /></div>
              <div class="loading"></div>
            </form>

        </div>

The contact.php is this:

<?php

//Retrieve form data. //GET - user submitted data using AJAX //POST - in case user does not support javascript, we'll use POST instead $name = ($_GET['name']) ? $_GET['name'] : $_POST['name']; $email = ($_GET['email']) ?$_GET['email'] : $_POST['email']; $thesubject = ($_GET['thesubject']) ?$_GET['thesubject'] : $_POST['thesubject']; $message = ($_GET['message']) ?$_GET['message'] : $_POST['message'];

//flag to indicate which method it uses. If POST set it to 1 if ($_POST) $post=1;

//Simple server side validation for POST data, of course, you should validate the email if (!$name) $errors[count($errors)] = 'Please enter your name.'; if (!$email) $errors[count($errors)] = 'Please enter your email.'; if (!$thesubject) $errors[count($errors)] = 'Please enter your subject.'; if (!$message) $errors[count($errors)] = 'Please enter your message.';

//if the errors array is empty, send the mail if (!$errors) {

// ====== Your mail here  ====== //
$to = 'Your Name <yourname@example.com>';   
//sender
$from = $name . ' <' . $email . '>';

//subject and the html message
$subject = 'yourwebsite.com / ' . $thesubject . ''; 
$message = '
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head></head>
<body>
<table>
    <tr><td>Name:</td><td>' . $name . '</td></tr>
    <tr><td>Email:</td><td>' . $email . '</td></tr>
    <tr><td>Message:</td><td>' . nl2br($message) . '</td></tr>
</table>
</body>
</html>';

//send the mail
$result = sendmail($to, $subject, $message, $from);

//if POST was used, display the message straight away
if ($_POST) {
    if ($result) echo 'Thank you! We have received your message.';
    else echo 'Sorry, unexpected error. Please try again later';

//else if GET was used, return the boolean value so that 
//ajax script can react accordingly
//1 means success, 0 means failed
} else {
    echo $result;   
}

//if the errors array has values } else {}

//Simple mail function with HTML header function sendmail($to, $subject, $message, $from) { $headers = "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n"; $headers .= 'From: ' . $from . "\r\n";

$result = mail($to,$subject,$message,$headers);

if ($result) return 1;
else return 0;

}

?>
