php form send to email inputted in email field - php

Question

I would like my simple php mailer form, to maintain sending me the filled out form; but also I would like to send them a confirmation message based on their inputted email address field - wondering if it's possible to send to email inserted in the form.
Eg: User fills out email address in the field as asked; this is where custom confirmation will be sent upon submit (along with form submission to me)
Note: // Same confirmation will be sent to every form user. I simply would like to write; with PHP - send this message to the email address inserted by current user in email field.
Updated:
I currently have the form submitting at my email:
$emailAddress = 'myemail#myemail.com';
I'm getting the fields with:
Email: '.$_POST['email'].'<br />
How do I edit it to send to the user inputted 'email as their email address' -- and spit out the generic message with it?
Recent attempt:
$emailAddress = 'myemail#myemail.com';
$to = $_POST['email'];
$message = 'Thank you for submitting the form on our website.!';
Form submits as normally; but doesn't send confirmation to '$to = $_POST['email'];'
Any pointers?
Complete code:
<?php
$emailAddress = 'myemail#myemail.com';
$to = $_POST['email'];
$message = 'Thank you for submitting the form on our website.!';
/* config end */
require "phpmailer/class.phpmailer.php";
session_name("fancyform");
session_start();
foreach($_POST as $k=>$v)
{
if(ini_get('magic_quotes_gpc'))
$_POST[$k]=stripslashes($_POST[$k]);
$_POST[$k]=htmlspecialchars(strip_tags($_POST[$k]));
}
$err = array();
if(!checkLen('name'))
$err[]='The name field is too short or empty!';
if(!checkLen('email'))
$err[]='The email field is too short or empty!';
else if(!checkEmail($_POST['email']))
$err[]='Your email is not valid!';
/* if(!checkLen('phone'))
$err[]='The phone field is too short or empty!'; */
/*if(!checkLen('subject'))
$err[]='You have not selected a subject!';*/
/* if(!checkLen('message'))
$err[]='The message field is too short or empty!';*/
if((int)$_POST['captcha'] != $_SESSION['expect'])
$err[]='The captcha code is wrong!';
if(count($err))
{
if($_POST['ajax'])
{
echo '-1';
}
else if($_SERVER['HTTP_REFERER'])
{
$_SESSION['errStr'] = implode('<br />',$err);
$_SESSION['post']=$_POST;
header('Location: '.$_SERVER['HTTP_REFERER']);
}
exit;
}
$msg=
'Name: '.$_POST['name'].'<br />
Phone: '.$_POST['phone'].'<br />
Email: '.$_POST['email'].'<br />
IP: '.$_SERVER['REMOTE_ADDR'].'<br /><br />
Referred By: '.$_POST['referer'].'<br /><br />
Message:<br /><br />
'.nl2br($_POST['message']).'
';
$mail = new PHPMailer();
$mail->IsMail();
$mail->AddReplyTo($_POST['email'], $_POST['name']);
$mail->AddAddress($emailAddress);
$mail->SetFrom($_POST['email'], $_POST['name']);
$mail->Subject = "A new Bridgetower.com Lead".mb_strtolower($_POST['subject'])." from ".$_POST['name']." | Via your contact form feedback";
$mail->MsgHTML($msg);
$mail->Send();
unset($_SESSION['post']);
if($_POST['ajax'])
{
echo '1';
}
else
{
$_SESSION['sent']=1;
if($_SERVER['HTTP_REFERER'])
header('Location: '.$_SERVER['HTTP_REFERER']);
exit;
}
function checkLen($str,$len=2)
{
return isset($_POST[$str]) && mb_strlen(strip_tags($_POST[$str]),"utf-8") > $len;
}
function checkEmail($str)
{
return preg_match("/^[\.A-z0-9_\-\+]+[#][A-z0-9_\-]+([.][A-z0-9_\-]+)+[A-z]{1,4}$/", $str);
}
?>
How could I output:
$to = $_POST['email'];
$message = 'Thank you for submitting the form on our website.!';

Answer 1

Have a look at PHPMailer. It's a pretty hand library for sending emails.
http://phpmailer.worxware.com
You can then just use GET or POST variables to send the email to the server

Answer 2

Sure you can do this. It's just as straight forward as it sounds. I recommend using a mailer helper like phpmailer, but you do it with the php mail function as well.
//check the email is real
if (filter_var($_POST['email'], FILTER_VALIDATE_EMAIL)) {
$to = $_POST['email'];
$subject = 'Thanks for filling out my form';
$message = 'The message';
$headers = 'From: me#mywebsite.com' . "\r\n" .
'Reply-To: webmaster#mywebsite.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
}
straight outta the manual

I believe you are looking for the built-in PHP mail() function. You post a form to your PHP page, with HTML like so:
<form action="your_php_script.php" method="post">
E-mail: <input type="text" name="email" />
<input type="submit" value="submit">
</form>
And your_php_script.php like so:
<?php
$to = $_POST['email'];
$subject = 'Confirmation E-mail';
$message = 'Thank you for submitting the form on our website.';
$headers = 'From: donotreply#yoursite.com' . "\r\n" .
'Reply-To: webmaster#yoursite.com' . "\r\n" .
'X-Mailer: PHP/' . phpversion();
mail($to, $subject, $message, $headers);
?>
