Setting Cookies with Javascript in Chrome

[FeralReason]

The following code works fine in IE8 and Firefox 3.5. Any idea why it does not work in Chrome ? Tried it both in localhost and on my web server -- no success.

In the header:
[code = php]
<?php
if((isset($_COOKIE["unique_id"]))&&isset($_COOKIE["users_resolution"])){
$screen_res = $_COOKIE["users_resolution"];
$unique_id = $_COOKIE["unique_id"];
}
else //means cookie is not found set it using Javascript
{
?>
[/code]

[code = html]

[/code]
[code = php]
<?php } ?>

// And in the ,body>

<?php
echo "Screen resolution: ".$screen_res."
";
echo "Unique ID: ".$unique_id."
";
?>
[/code]

Any help would be appreciated.

I haven't tested the javascript part of the code in Chrome yet, but the first place I would look would be the Cookies tab at
Tools | Options | Under the Hood | Privacy [Content settings...]

It isn't obvious how this

var the_cookie = "users_resolution="+ screen.width +"x"+ screen.height;
var the_cookie = "unique_id="+ uniqid();
var the_cookie = the_cookie + ";expires=" + the_cookie_date;

could be working in any browser. For starters, the second assignment obliterates the first.

Try something like this

var the_cookie = "users_resolution="+ screen.width +"x"+ screen.height;
    the_cookie += ";unique_id="+ uniqid();
    the_cookie += ";expires=" + the_cookie_date;

instead.
