在數據表庫中使用引導模式插入數據

Question

我想在引導模態的幫助下插入數據。 但是我在動作索引上有一個錯誤。 因此，我添加的按鈕無法運行。 我在編碼中做錯了什么嗎？

控制者

function user_action(){
        if ($_POST['action'] == "Tambah"){
            $data=array(
                'kodebayar' => $this->input->post('kodebayar'),
                'nama'      => $this->input->post('nama'),
                'harga'     => $this->input->post('harga')
            );
            $this->bpem_m->create($data);

        }
    }

模態視圖

                                      <div class="modal-dialog modal-sm">
                                        <form method= "post" id="form_pem">

JS

$(document).on('submit','#form_pem', function(event){
            event.preventDefault();
            var kodebayar = $('#kodebayar').val();
            var nama = $('#nama').val;
            var harga = $('#harga').val;

            if(kodebayar != '' && nama != '' && harga != ''){

                    }

                });

            }
            else{
                alert("Silahkan isikan semua data!");
            }

您可以使用serialize()

    var datastring = $("#form_pem").serialize();
$.ajax({
    type: "POST",
    url: "your url.php",
    data: datastring,
    dataType: "json",
    success: function(data) {
        //var obj = jQuery.parseJSON(data); if the dataType is not specified as json uncomment this
        // do what ever you want with the server response
    },
    error: function() {
        alert('error handing here');
    }
});

返回類型為json

編輯：我使用event.preventDefault來防止瀏覽器在這種情況下提交。
