How to send HTTP Cookies to another ZF2 Controller? - php

Question

I have two controllers. One of them is called OAMLController and the other is called LoginController. I would like to set HTTP Cookies in OAMLController and then make a call to LoginController and read it in this controller.
I know how to do this in PHP, but I don't know how to do this in Zend Framework 2.
PHP (OAML.php):
setcookie("_ga", "GA1.2.1622977711.1433494392", 0, "/", "http://gnsys.local");
setcookie("_gat", "1", 0, "/", "http://gnsys.local");
header("Location: http://gnsys.local/publico/login.php");
PHP (login.php):
$cookie = "";
foreach (getallheaders() as $name => $value) {
echo "$name: $value</br>";
if ($name == "Cookie")
$cookie = $value;
}
I have tried to follow the ZF2 tutorial but is so confusing.
More questions:
I have redirect to the other controller using $this->redirect()->toUrl($url).
$cookie = new \Zend\Http\Header\SetCookie("param1", "Hola", null, null, "http://gnsys.local", null, null, null, null);
$this->getResponse()->getHeaders()->addHeader($cookie);
return $this->redirect()->toUrl("http://gnsys.local/publico/login");
Because if I redirect with:
$controllerName = "LoginController";
$actionName = "index";
return $this->redirect()->toRoute(
"publico",
array(
"controller" => $controllerName,
"action" => $actionName
));
I always access to http://gnsys.local/publico and not to where I want http://gnsys.local/publico/login.
Another question, in LoginController I can't read the cookie. If I check the cookies via Firebug I can see that I have created the cookie in ".gnsys.local" domain and not in "gnsys.local" domain.
Why has that happened? If I make the redirect using toRoute or toUrl I create the cookie on the same domain ".gnsys.local" and not in "gnsys.local".
module.config:
'router' => array(
'routes' => array(
// The following is a route to simplify getting started creating
// new controllers and actions without needing to create a new
// module. Simply drop new controllers in, and you can access them
// using the path /application/:controller/:action
'publico' => array(
'type' => 'Literal',
'options' => array(
'route' => '/publico',
'defaults' => array(
'__NAMESPACE__' => 'Publico\Controller',
'controller' => 'Index',
'action' => 'index',
),
),
'may_terminate' => true,
'child_routes' => array(
'default' => array(
'type' => 'Segment',
'options' => array(
'route' => '/[:controller[/:action]]',
'constraints' => array(
'controller' => '[a-zA-Z][a-zA-Z0-9_-]*',
'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
),
'defaults' => array(
),
),
),
),
),
),
),

Finally, the redirection works fine with the solution from Jangya Satapathy. But I have a new problem and this is that I can't read the cookie because the domain is not correct. With these code I create a cookie with domain ".gnsys.local" and not with the domain "gnsys.local"
$cookie = new \Zend\Http\Header\SetCookie("param1", "Hola", null, null, "http://gnsys.local", null, null, null, null);
$this->getResponse()->getHeaders()->addHeader($cookie);
$controllerName = "login";
$actionName = "index";
return $this->redirect()->toRoute(
"publico/default",
array(
"controller" => $controllerName,
"action" => $actionName
));
So, when I try to write the value of cookie "param1", I've got the next error:
Notice: Undefined index: param1 in /var/www/html/gnsys/module/Publico/src/Publico/Controller/LoginController.php
If we check the value of the cookies with firebug, we've got the next screen capture:
What am I doing wrong?
Updated 3:
I don't understand what happened but getCookie is null.
getcookie IS NULL
And print_r($this->getRequest()->getCookie()); doesn't write anything.
$getcookie = $this->getRequest()->getCookie(); // returns object of Zend\Http\Header\Cookie
if ($getcookie != null)
echo "getcookie is NOT NULL";
else
echo "getcookie IS NULL";
print_r($this->getRequest()->getCookie());
return new ViewModel();
Updated 4:
I have found the cookie, but I cannot retrieve its value. To find the cookie, I have to indicate the path where I'm going to read it then.
$cookie = new \Zend\Http\Header\SetCookie("param1", "Hola", 0, "/publico/login/index", "gnsys.local");
$this->getResponse()->getHeaders()->addHeader($cookie);
$controllerName = "login";
$actionName = "index";
return $this->redirect()->toRoute(
"publico/default",
array(
"controller" => $controllerName,
"action" => $actionName
));
And, now I have this exit ...
getcookie is NOT NULL
Zend\Http\Header\Cookie Object ( [encodeValue:protected] => 1 [storage:ArrayObject:private] => Array ( [zdt-hidden] => 0 ) )
If I try to retrieve the value of the cookie through
$cookie = $getcookie->param1;
I've got the next error ...
Notice: Undefined index: param1 in /var/www/html/gnsys/module/Publico/src/Publico/Controller/LoginController.php on line 84
If I try to get all the values from $getcookie
foreach ($getcookie as $key => $value){
echo "Key: " . $key . " Value: " . $value . "<br />";
}
And I've got ...
Key: zdt-hidden Value: 0
Update 5:
I don't understand anything here. I'm not creating the cookie with these code!
$cookie = new \Zend\Http\Header\SetCookie("param1", "Hola", 0, "/", "http://gnsys.local");
$this->getResponse()->getHeaders()->addHeader($cookie);
$controllerName = "login";
$actionName = "index";
return $this->redirect()->toRoute(
"publico/default",
array(
"controller" => $controllerName,
"action" => $actionName
));
Checking the cookies using firebug we can't see the cookie.

Answer 1

In your cookie set action:
Public function cookiesetAction(){
$cookie = new \Zend\Http\Header\SetCookie($name, $value, $expires, $path, $domain, $secure, $httponly, $maxAge, $version);
$this->getResponse()->getHeaders()->addHeader($cookie);
return $this->redirect()->toRoute('cookieget'); //to your login controller
}
In your cookie get action:
public function cookiegetAction(){
$getcookie = $this->getRequest()->getCookie(); // returns object of Zend\Http\Header\Cookie
$getcookie->name1; // value1
$getcookie->name2; // value2
return new ViewModel();
}

Answer Update
Add child route followed by the main route.
return $this->redirect()->toRoute('publicio/default',array(
'controller'=>$controllername,
'action'=>$actioname
));
