PHP Question

How do I set the "From" address in a PHP contact form?

I have a problem with the PHP contact form I have created. When I enter information into the form and click submit the information is sent to an email address but there is no senders address attached to the email.

How do I create a seneders address so that when the user clicks sumbit it will send the email with thier email address as the sender.

The code for my form is shown below:

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>Email Form </title>
</head>
<body>

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

<?php
$ipi = getenv("REMOTE_ADDR");
$httprefi = getenv ("HTTP_REFERER");
$httpagenti = getenv ("HTTP_USER_AGENT");
?>

<input type="hidden" name="ip" value="<?php echo $ipi ?>" />
<input type="hidden" name="httpref" value="<?php echo $httprefi ?>" />
<input type="hidden" name="httpagent" value="<?php echo $httpagenti ?>" />

I am quite new to PHP and would appreciate all the help I can get with this.

Thanks in advance

Answer

You should do something like this:

$sanitizedEmail = filter_var($visitormail, FILTER_SANITIZE_EMAIL);
mail('recipient@email.com', $subject, $message, 'From: ' . $sanitizedEmail);

The line beginning $sanitizedEmail ensures that a user cannot send spam messages from your form.
