                    <div class="inputs col-md-12 col-sm-12 col-xs-12">
                        <label for="message">Message</label>
                        <textarea id="message" name="message" cols="50" rows="6" placeholder=""></textarea>
                    </div>

                </form>


PHP CODE: 

    <?php

if(isset($_POST['subject'], $_POST['email'], $_POST['name']))
{
    $to = "(MY EMAIL)";   
    $from = $_POST['email']; 
    $name = $_POST['name']; 
    $headers = "From: $from"; 
    $subject = $_POST['subject']; 

    error_reporting (E_ALL); 

    $fields = array(); 
    $fields{"name"} = "name"; 
    $fields{"email"} = "email"; 
    $fields{"subject"} = "subject"; 
    $fields{"message"} = "message";

    $body = "Message From " . $name .":\n\n"; foreach($fields as $a => $b){   $body .= sprintf("%20s: %s\n",$b,$_REQUEST[$a]); }

    $send = mail($to, $subject, $body, $headers);
 }
?>
