如何在我的php联系表单上修复我的电子邮件标题

Question

On my site when my customers fill out the form I receive the e-mail but the From section instead of showing what the customer input in the form I receive it as "[e-mail]". I would like to fix this so that I can directly reply to the e-mail the customer input into the form. Here is what my contact.php looks like below.

<?php
// variables start
$name = "";
$email = "";
$message = "";

$name =  trim($_POST['contactNameField']);
$email =  trim($_POST['contactEmailField']);
$message =  trim($_POST['contactMessageTextarea']);
// variables end

// email address starts
$emailAddress = '[e-mail]';
// email address ends

$subject = "mydomain.com | Mobile - Message From: $name";   
$message = "<strong>From:</strong> $name <br/> <strong>E-Mail:</strong> $email </br><br/> <strong>Message:</strong> $message";

$headers = 'From: '. $name . '<' . $email . '>' . "
";
$headers = 'Reply-To: ' . $email . "
";

$headers = 'MIME-Version: 1.0' . "
";
$headers = 'Content-type: text/html; charset=iso-8859-1' . "
";

//send email function starts
mail($emailAddress, $subject, $message, $headers);
//send email function ends
?>

An assignment to a variable (e.g. $headers = …) changes its value rather than appending to it. You should use the operator .= after initializing the variable first:

$headers = "";
$headers .= 'From' . $name . …

etc.
