PHP: Cookie problem - php

Question

Can anyone tell me what is wrong with my code?
<?php
class MyCookie
{
private $expiration = 0;
private $path = "";
private $domain = "";
private $secure = false;
private $httponly = false;
private $names = array();
public function __construct($e, $p = "/temp/", $s = false, $h = false) {
$this->expiration = $e;
$this->path = $p;
$this->domain = '.' . $_SERVER["SERVER_NAME"];
$this->secure = $s;
$this->httponly = $h;
}
public function getDomain() {
return $this->domain;
}
public function write($name, $value) {
return setcookie($name, $value, time() + $this->expiration, $this->path, $this->domain, $this->secure, $this->httponly);
}
public function delete($name) {
return setcookie($name, $value, time() - $this->expiration, $this->path, $this->domain, $this->secure, $this->httponly);
}
public function read($name) {
return $_COOKIE[$name];
}
}
session_start();
$cookie = new MyCookie(3600 * 24 * 30);
$cookie->write('name', 'jun');
echo $cookie->read('name');
?>
Somehow the cookie is not registering or showing up.

Answer 1

Cookie won't show up in $_COOKIE array until you reload the page (cookies are sent with HTTP response)

Answer 2

Two suggestions...
a) Try making the cookie visible to your whole domain, rather than a specified path
b) Get the Web Developer Toolbar for Firefox so you can easily view the current list of Cookies while you browse, which is really useful for de-bugging.

Answer 3

In PHP, the cookie is not actually set until the page reloads. You're creating the cookie then immediately trying to get a value from $_COOKIE, but that value doesn't exist yet in $_COOKIE.

Answer 4

Although it's generally not a good idea to alter values of any of the superglobal arrays, you can do this:
replace:
public function write($name, $value) {
return setcookie($name, $value, time() + $this->expiration, $this->path, $this->domain, $this->secure, $this->httponly);
}
with:
public function write($name, $value) {
$_COOKIE[$name] = $value;
return setcookie($name, $value, time() + $this->expiration, $this->path, $this->domain, $this->secure, $this->httponly);
}
setcookie will not moify the $_COOKIE superglobal.

Answer 5

Is your directory currently '/temp/'? If not, the cookie won't be passed along. Try not giving the new cookie a directory while you're at it, it will auto set to the correct one anyway.

Answer 6

Yup it isn't registering because it needs to reload the page.
It works like this:
_>Http Request
_>Php SetCookie
_>Http Response with cookie header
->New Http Request with cookie
->Php can read cookie now.
