can i use request to add text to my page from url

[cloudll]

I currently have a mailing list that my boss uses, when he adds an email there is no 'sucess message' to let him know it has worked.

 

The mailing list just redirects back to the add subscribers page. I wondered if its possible to add a request so when he adds an email I can redirect the url to this:

 

?page=addemail&message=your email was added

 

and then echo $message where I want it to appear.

 

I have added $message = $_REQUEST['message']; to my page but nothing is happening. Can I not use request like this?

After email added, add redirect

header('Location: some_location?added=ok');

And where it need add checking

if(isset($_GET['added']) && $_GET['added'] == 'ok') {
echo 'Email was added successfully';
}

It is the simplest way
