codeigniter cookie expiry problem

Question

I'm having a cookie issue, the expiry date on my cookie is always being set to At End Of Session which isn't what I want. I did a bit of goggling and it suggested it set the expire to time()+60*60*24*30 which I've done.

 //Create basket cookie
            $cookie = array(
                'name'   => 'basket_id',
                'value'  => $basket_id,
                'expire' => time()+60*60*24*30,
                'domain' => 'domain',
                'path'   => '/',
                'prefix' => '',
            );
            set_cookie($cookie);

I did wonder if it could be down to a Codeignter setting but my ci_session cookie has a normal expiry date. Thu, 09 Jun 2011 10:39:02 GMT

This is what I get when I view the cookie:

 Name   basket_id
 Value  28
 Host   .host
 Path   /
 Secure No
 Expires    At End Of Session

And here is an example of the array I'm passing to the cookie.

Array ( [name] => basket_id [value] => 30 [expire] => 1310202067 [domain] => host [path] => / [prefix] => ) 

Answer 1

Your expiry date is set incorrectly. You don't have to include the time(), as what you're setting is actually the expiry date from time().

When you have an incorrect expire value, it defaults to 0, which is set as your session's length instead.

Therefore it should be:

            $cookie = array(
            'name'   => 'basket_id',
            'value'  => $basket_id,
            'expire' => 86400*30,
            'domain' => 'domain',
            'path'   => '/',
            'prefix' => '',
        );
