$message = $_POST['message'];
//Validate first
if(empty($name)||empty($visitor_email))
    echo "Name and email are mandatory!";
    exit;
if(IsInjected($visitor_email))

>I do apologise if i seem slow, i am still very new to dreamweaver
Just to be clear, this is not an issue with learning dreamweaver. This is just a lack of understanding of HTML and PHP. You need to learn those first before trying to learn DW.
You have a form field named 'donorName' but are checking for a field named 'name'.
$name = $_POST['name'];
<input name="donerName" type="text"
You need to rename one or the other.
