PHP function to send form data

Question

I want to add a function to the end of my included file (code below) that will email the POST data that it validates. I have tried different ways to do this but to no avail? Everything is validating no problem but that is all! I basically have a form that validates and does nothing apart from that!

I just need a function to be added that will email the POST data:

    <?php
    // define variables and set to empty values
    $addDateErr = $nameErr = $emailErr = $subjectErr = $messageErr = $questionErr = "";
    $addDate = $name = $email = $subject = $message = $WebSearch = $SocialMedia =  $WordOfMouth = $Other ="";

if ($_SERVER["REQUEST_METHOD"] == "POST")
{
//Date
   if (empty($_POST["addDate"]))
   {$comment = "";}
   else
   {$comment = test_input($_POST["addDate"]);}

//Name
    if (empty($_POST["name"]))
    {$nameErr = "Name is required";}
    else
    {
    $name = test_input($_POST["name"]);
    if (!preg_match("/^[a-zA-Z ]*$/",$name))
    {
    $nameErr = "Only letters and white space allowed";
    }
    }

//Email
   if (empty($_POST["email"]))
   {$emailErr = "Email is required";}
   else
   {
   $email = test_input($_POST["email"]);
   if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email))
   {
   $emailErr = "Invalid email format";
   }
   }

//Subject
   if (empty($_POST["subject"]))
   {$comment = "";}
   else
   {$comment = test_input($_POST["subject"]);}

//Message
   if (empty($_POST["message"]))
   {$messageErr = "A message is required";}
   else
   {$comment = test_input($_POST["message"]);}

//Question
    if (isset($_POST['Question']))
    {
    $menuVar = $_POST['Question'];
    } else {
    $menuVar = "----------";}
}
function test_input($data)
{
     $data = trim($data);
     $data = stripslashes($data);
     $data = htmlspecialchars($data);
     return $data;
}
?>

You probably will want some sort of library that does the job of sending the e-mail for you.

Here are some:

https://github.com/PHPMailer/PHPMailer

http://swiftmailer.org/

You can use this to send emails with php:

mail("youremail@uptoyou.com", "Subject", "Message", "From:sender@test.com");

In your case you could do something like:

mail("receiver@test.com", $_POST["subject"], "Message:" . $_POST["message"] . "Question:" . $_POST['Question'], "From:" . $_POST["email"]);

You need to assign all your validated form inputs to different variables; for some reason, you reused $comment for several of them. Once you have them in variables, you can do something like this:

$mail_body = <<<EOM
Name: $name
Email: $email
Subject: $subject
Date: $date
Question: $question
Message: $message
EOM ;

mail("youraddress@yourdomain.com", "Form submission", $mail_body, "From: someaddress@yourdomain.com");
