I have the following php code on my HTML page:
<body>
 <?php
        if ($_POST) {
            $message = 'Name :' . $_POST['name'] . "\n" .
                    'Email :' . $_POST['email'] . "\n" .
                    'Phone :' . $_POST['phone'] . "\n" .
                    'Date :' . $_POST['book'] . "\n" .
                    'Message :' . $_POST['message'];
            mail('ruan@gmail.com', 'Contact-us Form', $message);
        }
        ?>
And HTML as the following:
<form method="post" action="contact.php" onsubmit="return valid()" enctype="multipart/form-data">
      <ul>
        <li>
          <p class="left">
            <p>Name</p>
            <input type="text" name="name" placeholder="John Doe" />
          </p>
   .....
 </form>
Now i have changed the email address to check if that could be the problem but still, I don't receive any email.
