Kamu belum tau caranya menghubungkan codeIgniter dengan database MySql kamu ya ? Kita tahu kok kamu butuh panduannya, kamu hanya perlu mengatur file config/database.php . Biar makin paham makanya simak sampai habis panduan berikut.

STEP 2. Hubungkan codeIgniter dengan database buka file config database codeIgniter yang ada di application.config/database.php
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => '',
'password' => '',
'database' => '',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
STEP 3. Atur database kamu dengan masukkan hostname, username database, password dan nama database seperti dibawah.
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'sobatjagoan'
Passwordnya bisa kamu isi sendiri sesuai dengan keinginanmu loh
STEP 4. Memanggil library database codeigniter perlu kamu lakukan dari function construct() pada controller, method atau autoload codeIgniter. Berikut ini kamu cara untuk mengarah ke load library CodeIgniter
$autoload['libraries'] = array();
STEP 5. Setelah ini kamu bisa tambahkan database.
$autoload['libraries'] = array('database');
Pengenalan Model pada CodeIgniter
STEP 1. Buat model dengan nama yang kamu inginkan, contohnya sobatjagoan.php melalui application/models/sobatjagoan.php
| 1
2 3 4 5 6 7 |
<?php
class M_data extends CI_Model{ function ambil_data(){ return $this->db->get(‘user’); } } |
Saat membuat class model sobatjagoan, kamu sebaiknya diawali dengan huruf besar/kapital
STEP 2. Buat sebuah function ambil_data() pada model sobatjagoan_data.
Syntax $this->db->get() bisa kamu gunakan untuk mengambil data dari database sob, dengan cara nama table yang ingin kamu ambil datanya bisa diletakkan dalam parameternya, sehingga seperti berikut sob :
$this->db->get('user');
STEP 3. Buat function pada controller, sebagai contoh menggunakan controller_belajar.php. application/controller/belajar.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Belajar extends CI_Controller {
function __construct(){
parent::__construct();
$this->load->model('m_data');
}
function user(){
$data['user'] = $this->m_data->ambil_data()->result();
$this->load->view('v_user.php',$data);
}
}
Dari syntax diatas kamu bisa perhatikan untuk memanggil function ambil_data() pada model sobatjagoan_data. Fungsi dari result() sendiri berguna untuk menjadikan array. Disini kita mengambil data dari fungsi ambil_data pada model sobatjagoan_data dan dimasukkan ke variabel untuk diparsing ke dalam view v_user.php
STEP 4. Buat sebuah view dengan nama v_user.php pada view akan menampilkan data dari database yang kita parsing. application/view/v_user.php
