ajax passing string getting array

Question

I'm using Laravel Framework, and I'm trying to create an Ajax request, so I can send the Form data to the Controller. The thing is, I'm passing a string but in the controller, when I try JSON_decode it says that I'm giving it an array and not a string. What am I doing wrong?

View (ajax)

function getData() {
   var name = $('#name').val();
   var tin = $('#tin').val();
   var password = $('#password').val();
   var currency = $('#currency').val();

   var data = {"name": name, 'tin': tin, 'password': password, 'currency': currency};
   var obj = JSON.stringify({"name": name, 'tin': tin, 'password': password, 'currency': currency});
   console.log(obj);
   $.ajax({
      type: "POST",
      url: "teste",
      data: obj,
      success: function (result) {
        alert(result);
      }
   });
}

Controller:

 $data = $_POST;
    //$string = json_encode($data);
    $test = json_decode($data);
    echo $test->name ;
    //echo "data: $string, gravada com sucesso!";
    die;

If someone could help me...

Just solved.

$.ajax({ 
   type: "POST",
   url: "teste",
   data: {"name": name, 'tin': tin, 'password': password, 'currency': currency},
   success: function (result) {
      alert(result);
    }
});

And in the controller, I encoded and then decoded..and it worked Thanks :)

$_POST is an array, change json_decode to json_encode

No need to use JSON.stringify

Remove JSON.stringify and directly pass data

or If you want to read in json format, then

url: "1.php", data: {"key":obj},

In your example if you want to pass json string in than you need to pass OBJ as a param:

<script type="text/javascript">
var data = {"name": name, 'tin': tin, 'password': password, 'currency': currency};
var obj = JSON.stringify({"name": name, 'tin': tin, 'password': password, 'currency': currency});

$.ajax({
type: "POST",
url: "<?=g('base_url')?>home/index",
data: "obj="+obj, // add as a param
success: function (result) {
alert(result);
}
});
</script>

In PHP, you can get object in $_POST as:

$data = $_POST['obj'];
$test = json_decode($data);
echo $test->name;

UPDATE:

Second solution you have already updated in your question.
