Data loss in session

I’m making a form with steps in Ajax. The idea is to each step take the form data, play an array and store the array in the session, so I can manipulate all the data in the last step:

Ajax formulario1:

$('.next').click(function(){
   $.post({
      url: '/teste_mvc/turma/step1/' ,
      data: $('#step1').serialize(),
      success: function (e){alert(e);}
});

Action step1

public function Step1(){
    session_start();
    $ses = array();
    foreach($_POST as $k=>$p){
        $ses[$k] = $p;
    }
    $_SESSION['step1'] = $ses;
    print_r($_SESSION['step1']);
    exit;
}

So far the application works as it should, problem is with the second step forward:

Ajax formulario2:

 $('.next').click(function(){
     $.post({
         url: '/teste_mvc/turma/step2/' ,
         data: $('#step2').serialize(),
         success: function (e){alert(e);}
      });
 });

Action step2

 public function Step2(){
    session_start();
    $ses = array();
    foreach($_POST as $k=>$p){
        $ses[$k] = $p;
    }
    $_SESSION['step2'] = $ses;
    print_r($_SESSION['step1']);
    print_r($_SESSION['step2']);
    exit;
}

When returning session data back to ajax the value of $_SESSION['step2'] PHP can recover, but the $_SESSION['step1'] are lost, with PHP returning undefined for her.

I must be making a silly mistake, but I’m trying to make it work here and everything I know has been applied.

php jquery ajax

  • These foreach to go through the $_POST array are unnecessary, for that it was enough $_SESSION['step1'] = $_POST;

  • @Miguel I already solved this problem, is that I created a custon mvc for the project and was tending to leave the global session. It was enough to call the session with each request that the data was not lost anymore

  • This wasn’t the point of the question, it’s just to point out that redundancy in your code

The problem in the code is quite simple and really is silly, you are restarting the sessions, the session_start() should be used only 1 time. You can much call it at the beginning of the code. Strongly do not recommend using it within a function!

Solution: What you may be doing and why session_start() out of functions, starting only once. At the beginning of the code preferably!
