Please do! It gives you an idea how URL's in CI work.
You can't run a URL that refers to a view, model, library etc. CI expects a controller name and a method name (function) inside that controller, optionally followed by one or more parameters.
Like: http://website_base_url/controller_name/...am2/paramn}
Routes are a way to manipulate that, but you'll first need to understand the basics.

I'll come back later to give you an example of AJAX.

I have read that and am well aware of how URL's pass parms in CI. I use it all over my app. This is more of a question of sending data from a controller function to a view. Here is what I have in a function in my controller;

$data = array('campaign' => $campaign);
$str = $this->db->update_string('users', $data, $where);
$this->db->query($str); //set active to 1
$iRc = $this->input->post($campaign); //THIS IS THE LINE THAT DOESN'T WORK

The first 3 lines update the database and this seems to work fine. The last line is the problem. I want to send the campaign name to the jquery that is now running in the view. Here is the head section of the view:

<head>
<meta http-equiv="content-type" content="text/html; charset=UTF-8" />

<link href="/assets/css/screen.css" rel="stylesheet" type="text/css" />


<script src="/assets/js/jquery-1.4.2.js" type="text/javascript"></script>
<script src="/assets/js/global.js" type="text/javascript"></script>

/* Global JavaScript File for working with jQuery library */

$.when().then{
var elem = document.getElementById('myCamp');
elem.text = campaign;
}
</head>

Finally, here is the defintion of the button:
<button id="myCamp" class="btn pull-right btn-danger navbar-btn ">Active Campaign: None</button>

I am not sure what $.when does? I probably need to loop and wait until that post() in the controller has an updated campaign label. Or wait for a "post event'. So the two parts a) sending the string b) waiting for the string
are my issue. I am only going in one direction: from controller to view.

thanks for your help, btw
