I was trying to setup a contact form on my website. I have downloaded an example.

In this contact form, there is a $EmailFrom in the email message. Now, I wanna add this $EmailFrom to the sender field in the email that's sent.

I tried:

$EmailFrom = "$EmailFrom";

But I looks like that is not gonna work ;(

<?php

$EmailFrom = "[e-mail]";
$EmailTo = "[e-mail]";
$Subject = "Contactformulier";
$Name = Trim(stripslashes($_POST['Name']));
$Tel = Trim(stripslashes($_POST['Tel']));
$Email = Trim(stripslashes($_POST['Email']));
$Message = Trim(stripslashes($_POST['Message']));

// validation
$validationOK=true;
if (!$validationOK) {
  print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
  exit;
}

// prepare email body text
$Body = "";
$Body .= "Name: ";
$Body .= $Name;
$Body .= "
";
$Body .= "Tel: ";
$Body .= $Tel;
$Body .= "
";
$Body .= "Email: ";
$Body .= $Email;
$Body .= "
";
$Body .= "Message: ";
$Body .= $Message;
$Body .= "
";

// send email
$success = mail($EmailTo, $Subject, $Body, "From: <$EmailFrom>");

// redirect to success page
if ($success){
  print "<meta http-equiv=\"refresh\" content=\"0;URL=contactthanks.php\">";
}
else{
  print "<meta http-equiv=\"refresh\" content=\"0;URL=error.htm\">";
}
?>

I expected this: email sender

</div>
