Codeigniter can't read cookie set with Javascript

Question

I am trying without success to read a cookie in codeigniter that has been set in the browser with Javascript.

The cookie is set in the browser as follows:

// cookieContents is an array of integers
strForCookie = JSON.stringify(cookieContents);
date.setTime(date.getTime() + (2 * 24 * 60 * 60 * 1000));	// 2 days
$.cookie('savedPlaces', strForCookie, { expires: date });

I have checked in the browser that the cookie is set properly.

On the server I have the following codeigniter code in a controller:

$this->load->helper('cookie');
$savedPlaces = $this->input->get_cookie('savedPlaces');
if ($savedPlaces == false) echo("Cookie doesn't exist!");
else echo("Cookie is: ".$savedPlaces);

The controller function is called by the following html:

<a href="/browser/saved/">Saved searches</a>

I have never used cookies before so suspect I am doing something fundamentally wrong. Can anyone illuminate me?

Are you sure you do not have an already existing cookie with the same name? It sometimes give error when you set cookies with same names. — Osama Yawar

Not sure what you mean by an already existing cookie? The browser successfully writes the cookie 'savedPlaces', shouldn't the server be able to read this cookie? How can I create a cookie with the same name? Doesn't it just overwrite the cookie rather than creating a new one with the same name? — Bill Noble

Well i had a similar problem and in the end i found that it was conflicting with CodeIgniters default cookie setter — Osama Yawar

Can you advise what I can do to ensure this isn't happening? I am not using codeigniter to set any cookies. These are set client side. — Bill Noble

Add {path: '/'} option to make the cookie available to your entire site or '{path: '/browser/saved/'}' to receive the cookie only on this controller function.

$.cookie('savedPlaces', strForCookie, {expires: date, path: '/'});

By default the cookie path is set to the current page's path and will only be available to that path.
