codeigniter ajax请求与会话

Question

cant get session values through ajax request

this is my ajax req

$.post(url, payload, 
    function(returnedData){
        console.log(returnedData); //does not print session values it seems session has restarted
         var jsonData = JSON.parse(returnedData);

         $('#cart').empty().append(jsonData.data);
});

output in console.log

    Array
(
    [__ci_last_regenerate] => 1473660791
)

assigning session variable

public function test($id=null)
{
    $_SESSION['tot']=1;
}

testing not using ajax

public function addToCart($id=null) //note that this is also the control for my ajax req
{            
        print_r($_SESSION);
        die('0');
}
public function test1()
{
    print_r($_SESSION); // it prints fine
}

output

Array ( [__ci_last_regenerate] => 1473660731 [tot] => 1 )

I autoload my session library. CI says it doesnt matter on how you access session variables either using session magic or the php as long as it exist.

Answer 1

Hello can you use please default codeignitor session and please mention which url you make ajax request and php code of ajax request

like

$this->session->set_userdata('tot',1);

and then print the session array like this

echo "<pre">;print_r($this->session->userdata('tot'));

Answer 2

Your code should be

 public function test($id=null)
    {
        $this->session->set_userdata('tot', 1);
        //instead $_SESSION['tot']=1;
    }
    public function addToCart($id=null) //note that this is also the control for my ajax req
    {            
            $session_id = $this->session->userdata('session_id');
echo $session_id;
    }
    public function test1()
    {
        //print_r($_SESSION); // it prints fine
$session_id = $this->session->userdata('session_id');
echo $session_id;
    }

and make sure session library loaded ($this->load->library('session');)
