codeigniter - How can we check data in controller sent by ajax (not in response) in codeigniter?

Question

I want to send array data from javascript to a view page..But the array isn't getting passed to the view page. The codes are described below:

//array getting passed from this page

<input type="button" name="b">
<script src="<?php echo base_url().'assets/js/' ?>jquery.min.js"></script>
<script type="text/javascript">
    $(function(){
        $("input[type='button']").click(function(){
            question_array=[];
            question_array['what is our nationality?']='Bangladeshi';
            question_array['what is our national fish?']='Ilish';
            number=10;
            jQuery.ajax({
                type: "POST",
                url: "<?php echo base_url(); ?>" + "admin/test",
                dataType: 'json',
                data: {question_array: question_array,number:number},
                success: function(result) {
                    if (result) {
                           window.location="<?php echo base_url().'admin/test_page'; ?>";
                    }
                }
            });
        });
    });
</script>

`

In my controller::

public function test()
{
    $question_array = $this->input->post('question_array');
    $number         = $this->input->post('number');
    $this->session->set_flashdata('number', $number);
    $this->session->set_flashdata('question_array', $question_array);

    echo json_encode($number, $question_array);
}
function test_page()
{
    $this->load->view('admin/test_page');
}

//The page where I'm sending the array(Question_array not found)

$number         = $this->session->flashdata('number');
$question_array = $this->session->flashdata('question_array');
echo $number;
print_r($question_array);

我希望下面的代码可以帮助你。您需要使用 stringify 发布字符串 i 更正 JSON 格式。服务器将接收 json 并将其解码为对象。

function send(){
var url = "http://localhost/some_url_here";

var data = JSON.stringify({
    Bangladeshi: 'what is our nationality?',
    Ilish: 'what is our national fish?'
});          
$.ajax({
    url: url,
    type: "POST",
    dataType: "json",
    data: data,
}).done(function(output){
    alert('output is '+ JSON.stringify(output));
});

}

function receive() 
{
    $result = '';

    $stream_clean = $this->security->xss_clean($this->input->raw_input_stream);
    $request = json_decode($stream_clean);
    $Bangladeshi = $request->Bangladeshi;
    $Ilish = $request->Ilish;
    $result = array("status" => 200, "id" => $Bangladeshi+$Ilish);
    header('Content-Type: application/json');
    echo json_encode($result);
}
