CRUD tanpa reload page dengan ajax dan datatable menggunakan codeigniter

AJAX (Asynchronous Javascript And XML) memang memiliki kehandalan dalam mengakses data dari database, dikarenakan Asynchronous. Asynchronous dapat dianalogikan sebagai berikut:

“Suatu restauran memiliki pelayan, koki, dan pelanggan. Pelayan menerima orderan dari pelanggan dan mengantarkannya ke koki untuk dimasak. Pelayan dapat menerima banyak orderan dalam waktu bersamaan, tanpa harus menunggu orderan sebelumnya selesai.”

Begitu juga dengan Asynchronous, Langsung mengeksekusi proses baru tanpa menunggu proses sebelumnya selesai. Dengan begitu dapat menghemat bandwidth server.

Hmm..,Keren bukan?

Pada tutorial CRUD dengan ajax dan datatable menggunakan codeigniter ini, saya menggunakan Modal BOOTSTRAP sebagai penampung form. Modal BOOTSTRAP memungkin kita membuat aplikasi CRUD(Create Read Update Delete) hanya dalam satu halaman saja. Sebelum munculnya modal bootstrap, untuk membuat aplikasi CRUD memelukan beberapa halaman. Yaitu halaman untuk menampilkan data dari database, halaman form add, dan halaman form edit.

OK, tanpa basa-basi lagi langsung saja kita mulai!



1. Buka controller Barang.php ubah menjadi seperti berikut:

<?php
class Barang extends CI_Controller{
    function __construct(){
        parent::__construct();
        $this->load->model('m_barang');
    }
    function index(){
        $this->load->view('v_barang');
    }
    function data_barang(){
        $data=$this->m_barang->barang_list();
        echo json_encode($data);
    }
    function get_barang(){
        $kobar=$this->input->get('id');
        $data=$this->m_barang->get_barang_by_kode($kobar);
        echo json_encode($data);
    }
    function simpan_barang(){
        $kobar=$this->input->post('kobar');
        $nabar=$this->input->post('nabar');
        $harga=$this->input->post('harga');
        $data=$this->m_barang->simpan_barang($kobar,$nabar,$harga);
        echo json_encode($data);
    }
    function update_barang(){
        $kobar=$this->input->post('kobar');
        $nabar=$this->input->post('nabar');
        $harga=$this->input->post('harga');
        $data=$this->m_barang->update_barang($kobar,$nabar,$harga);
        echo json_encode($data);
    }
    function hapus_barang(){
        $kobar=$this->input->post('kode');
        $data=$this->m_barang->hapus_barang($kobar);
        echo json_encode($data);
    }
}

2. Buka model M_barang.php ubah menjadi seperti berikut:

<?php
class M_barang extends CI_Model{
    function barang_list(){
        $hasil=$this->db->query("SELECT * FROM tbl_barang");
        return $hasil->result();
    }
    function simpan_barang($kobar,$nabar,$harga){
        $hasil=$this->db->query("INSERT INTO tbl_barang (barang_kode,barang_nama,barang_harga)VALUES('$kobar','$nabar','$harga')");
        return $hasil;
    }
    function get_barang_by_kode($kobar){
        $hsl=$this->db->query("SELECT * FROM tbl_barang WHERE barang_kode='$kobar'");
        if($hsl->num_rows()>0){
            foreach ($hsl->result() as $data) {
                $hasil=array(
                    'barang_kode' => $data->barang_kode,
                    'barang_nama' => $data->barang_nama,
                    'barang_harga' => $data->barang_harga,
                    );
            }
        }
        return $hasil;
    }
    function update_barang($kobar,$nabar,$harga){
        $hasil=$this->db->query("UPDATE tbl_barang SET barang_nama='$nabar',barang_harga='$harga' WHERE barang_kode='$kobar'");
        return $hasil;
    }
    function hapus_barang($kobar){
        $hasil=$this->db->query("DELETE FROM tbl_barang WHERE barang_kode='$kobar'");
        return $hasil;

3. Buka View v_barang.php ubah menjadi seperti berikut:
