If the undefined index message is related to the $_POST variables it is because when you normally open a page you execute a GET request, when you submit the form, instead, you perform a POST request and only in this case the $_POST array is populated.

So from:

$name = $_POST['name'];

You will get:

Notice: Undefined index: name ...

In order to stop this you can place an IF statement checking if the $_POST array is true:

if($_POST)
{
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: Demo'; 
    $to = 'info@domain.com'; 
    $subject = 'Hello';
    $human = $_POST['human'];
    $body = "From: $name\n E-Mail: $email\n Message:\n $message";
    if ($_POST['submit'] && $human == '4') {                 
        if (mail ($to, $subject, $body, $from)) { 
        echo '<p>Your message has been sent!</p>';
    } else { 
        echo '<p>Something went wrong, go back and try again!</p>'; 
    } 
    } else if ($_POST['submit'] && $human != '4') {
    echo '<p>You answered the anti-spam question incorrectly!</p>';
    }
}

In the event you had more than one form, you can check to see if a particular input elment of type "submit" executed the post. For example..

<?php

if(isset($_POST['submit'])) 
{
    // input with name=submit was clicked.
    // do stuff;
}

?>

<input type="submit" value="Submit" name="submit" />

thanx it Works fine but how do i get the echo mesage to appear on the same page instead of in a blank page

Member Avatar for JorgeM

You will post to the same page as long as the action attribute specifies the same page.

<form method="post" action="contact.php">
