如何从ajax在codeigniter中插入会话多个数组

Question

form input

<form id='form'>
  <input type="text" name="nama" value="">      
  <input type="text" name="email" value="">     
  <input type="button" id='button' name="button" value="kirim">
</form>
<div id='hasil'></div>

ajax sent

$(document).on('click', '#button', function(event) {
  event.preventDefault();       
  var data = $('#form').serializeArray();
  $.ajax({
    data : {data : data},
    url:'data/test_ajax',
    method:'post',
    success:function (data_ajax){
      console.log(data_ajax);
    }
  });
});

sent to data/test_ajax

public function test_ajax(){
    $data = $this->input->post('data');

    $get_session = $this->session->userdata('data');
    for ($i=0; $i < 1000; $i++) { 
        if ($get_session[$i]=="") {
            $dat['data'][$i]['nama'] = $data[0]['value'];
            $dat['data'][$i]['email'] = $data[1]['value'];
            $set_session = $this->session->set_userdata($dat);
            break;
        }
    }

    $get_session = $this->session->userdata('data');
    print_r($get_session);
}

how to insert to session with codeigniter every adding data from ajax, result like as :

[0] => Array ( [nama] => test [email] => test )

[1] => Array ( [nama] => testtt [email] => testttt )

[2] => Array ( [nama] => aaa [email] => aaaaa )

[3] => Array ( [nama] => aa [email] => sdfaaaaasdfdsf )

Answer 1

I dont ktow how works codeinteger get/set-userdata, but try this

$get_session = $this->session->userdata('data');
$get_session[] = Array('nama'=>$data[0]['value'], 'email' => $data[1]['value']);
$set_session = $this->session->set_userdata('data',$get_session);

OT safest way to pass data to script would be

var datastring = $("#form").serialize();
    $.ajax({
        type: "POST",
        url: "your url.php",
        data: datastring,
        success: function(data) {
             alert('Data send');
        }
    });
