I have the following PHP for sending a contact form:

<?php
    if(isset($_POST['name']) && $_POST['email'] && $_POST['message'])
    {
        $companyname = $_POST['company-name'];
        $name = $_POST['name'];
        $email = $_POST['email'];
        $areacode = $_POST['areacode'];
        $phone = $_POST['phone'];
        $country = $_POST['country'];
        $message = $_POST['message'];

        $to = "";
        $subject = "New Message From: $name";
        $message .= "$messege";
        $headers = "From: $email";

        $mailed = ( mail($to,$subject,$message,$headers) );

        if( isset($_POST['ajax']))
            $response = ($mailed) ? "1" : "0";
        else
            $response = ($mailed) ? "<h2>Success!</h2>" : "<h2>Error! There was a problem with sending.</h2>";

        echo $response;
    }
    else
    {
        echo "Form data error!";
    }
?>

in the "$message .= "$messege";" I believe that what will be sent and viewed in the email client right? How can I add the area code, phone number and country as well as the message?

Ok i post the full code to wrap things up:

<?php

if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['message'])) {
    $companyname = $_POST['company-name'];
    $name = $_POST['name'];
    $email = $_POST['email'];
    $areacode = $_POST['areacode'];
    $phone = $_POST['phone'];
    $country = $_POST['country'];
    $message = $_POST['message'];

    $to = "support@loaidesign.co.uk";
    $subject = "New Message From: $name";
    $message = "$message
Area Code: $areacode
Phone Number: $phone
";
    $headers = "From: $email";

    $mailed = mail($to, $subject, $message, $headers);

    if (isset($_POST['ajax'])) {
        $response = ($mailed) ? "1" : "0";
    } else {
        $response = ($mailed) ? "<h2>Success!</h2>" : "<h2>Error! There was a problem with sending.</h2>";
    }

    echo $response;
} else {
    echo "Form data error!";
}

Simply concat the message string with the info you want to add:

$message = "From: $name

$message

Phone: $phone, Country: $country, ...";

try this:

$headers = "From: " . strip_tags($_POST['email']) . "
";
$headers .= "Reply-To: ". strip_tags($_POST['email']) . "
";
$headers .= "CC: cc@example.com
";
$headers .= "MIME-Version: 1.0
";
$headers .= "Content-Type: text/html; charset=ISO-8859-1
";

$new_message = $message;
$new_message .= $areacode.$phone;

$mailed = ( mail($to,$subject,$new_message,$headers) );
