below is my contact form script
<?php
if(!empty($errors)){
echo "<p class='err'>".nl2br($errors)."</p>";
}
?>
<div id='contact_form_errorloc' class='err'></div>
<form method="POST" name="contact_form" action="mailer.php">
<p>
<label for='name'>Name: </label><br>
<input type="text" name="name" value='<?php echo htmlentities($name) ?>'>
</p>
<p>
<label for='email'>Email: </label><br>
<input type="text" name="email" value='<?php echo htmlentities($visitor_email) ?>'>
</p>
