How to manage cookies in Phalcon PHP

Question

I have an application written with PhalconPHP. I used phalcon command line tools to build up things. I want to implement a "remember-me" option for users. However, if I understand correctly, PhalconPHP creates cookies with unique session ids and an encryption (encryption part, I like). So, whenever users session is gone, I lost access to the cookie. How can I fix this?

I actually do not destroy the session, I just use cmd + Q to quit my browser after I set session and cookie. I tried with encryption and without.

To be more clear : I do not get any errors. Just can't find the cookie back. I got "no cookie found" echoed after I close the browser and turn it on again.

As a code example, below is how I try to achieve this feature;

My services.php

/**
 * Start the session the first time some component request the session service
 */
 $di->setShared('session', function () {
    $session = new SessionAdapter();
    //$session->setId('crowgadgets'); 
    $session->start();

    return $session; 
 });


/**
* Set crypt for cookie encryption
*/

$di->set('crypt', function () {
    $crypt = new Crypt();

    $crypt->setKey('-#1+%&/k5l6&olr$'); // Use your own key!

    return $crypt;
});


/**
* Set cookie universal
*/
$di->setShared('cookies', function () {
    $cookies = new Cookies();

    //$cookies->useEncryption(true);

    return $cookies;
});

Set the cookie in controller;

$this->cookies->set('remember-me', $auth['id'], time() + 15 * 86400);

Get the cookie in controller;

if ($this->cookies->has('remember-me')) {
    $user_id = (string) $this->cookies->get('remember-me');
} else {
    echo "no cookie found";
    die();
}

I do not get any errors. Just can't find the cookie back. I got "no cookie found" after I close the browser and turn it on again. — Süha Boncukçu, Feb 11 '16 at 11:15
Do you have 'no cookie found" after page refresh, or only after restarting browser? — yergo, Feb 11 '16 at 11:23
@yergo only after restarting the browser but not only on my computer. Other users have this issue too. — Süha Boncukçu, Feb 11 '16 at 11:53
@SühaBoncukçu Please store your cookie with path. Like this : `$this->cookies->set('remember-me', $auth['id'], time() + 15 * 86400,"/");` — Mr. Engineer, Feb 11 '16 at 12:08
@Mr.Engineer , thanks, it seems like it works. Could you put this as an answer and please explain why did it work? — Süha Boncukçu, Feb 11 '16 at 16:47

Syntax for cookie :

setcookie(name,value,expire,path,domain,secure,httponly);

About path parameter :

Optional. Specifies the server path of the cookie. If set to "/", the cookie will be available within the entire domain. If set to "/php/", the cookie will only be available within the php directory and all sub-directories of php. The default value is the current directory that the cookie is being set in

By default cookie get created with the current path until you change it to save cookie on any other path or '/'

The path on the server in which the cookie will be available on. If set to '/', the cookie will be available within the entire domain. If set to '/foo/', the cookie will only be available within the /foo/ directory and all sub-directories such as /foo/bar/ of domain. The default value is the current directory that the cookie is being set in.

You can read more about path and cookies from this links :

http://php.net/manual/en/function.setcookie.php

http://www.w3schools.com/php/php_cookies.asp

http://www.tutorialspoint.com/php/php_cookies.htm

For me question is, why browser does not save cookie for next session if `path` is not set.. — yergo, Feb 12 '16 at 09:03
It's not like that. You can access cookie but on the same page where you've created your cookie.As per docs if you dont set your path then it will only accessible for current file or directory. — Mr. Engineer, Feb 12 '16 at 09:21
