Tugas
Menghubungkan database dengan website
Langkah-langkah
1. Membuat database
a. buka PHPMyadmin
b. buat database baru dengan nama tokobuah
c. buat tabel products dengan 5 kolom
Kolom yang dibutuhkan :
1. product_id (Primary Key) bertipe string dengan panjang 64
2. name bertipe string dengan panjang 255
3. price bertipe integer
4. image bertipe string dengan panjang 255
5. description bertipe TEXT
1. product_id (Primary Key) bertipe string dengan panjang 64
2. name bertipe string dengan panjang 255
3. price bertipe integer
4. image bertipe string dengan panjang 255
5. description bertipe TEXT
2. Koonfigurasi codeigniter
a. buka config/database.php, kemudian isi :
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'tokobuah',
'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
);
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'tokobuah',
'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
);
b. buka config/autoload.php.
c. cari $autoload['libraries'] dan tambahkan database dan session
c. cari $autoload['libraries'] dan tambahkan database dan session
$autoload['libraries'] = array('database', 'session');
3. Membuat Model untuk Tabel
a. buat file baru di dalam direktori application/model/ dengan nama Product_model.php, isi :
<?php defined('BASEPATH') OR exit('No direct script access allowed');
class Product_model extends CI_Model
{
private $_table = "products";
public $product_id;
public $name;
public $price;
public $image = "default.jpg";
public $description;
public function rules()
{
return [
['field' => 'name',
'label' => 'Name',
'rules' => 'required'],
['field' => 'price',
'label' => 'Price',
'rules' => 'numeric'],
['field' => 'description',
'label' => 'Description',
'rules' => 'required']
];
}
public function getAll()
{
return $this->db->get($this->_table)->result();
}
public function getById($id)
{
return $this->db->get_where($this->_table, ["product_id" => $id])->row();
}
public function save()
{
$post = $this->input->post();
$this->product_id = uniqid();
$this->name = $post["name"];
$this->price = $post["price"];
$this->description = $post["description"];
return $this->db->insert($this->_table, $this);
}
public function update()
{
$post = $this->input->post();
$this->product_id = $post["id"];
$this->name = $post["name"];
$this->price = $post["price"];
$this->description = $post["description"];
return $this->db->update($this->_table, $this, array('product_id' => $post['id']));
}
public function delete($id)
{
return $this->db->delete($this->_table, array("product_id" => $id));
}
}
class Product_model extends CI_Model
{
private $_table = "products";
public $product_id;
public $name;
public $price;
public $image = "default.jpg";
public $description;
public function rules()
{
return [
['field' => 'name',
'label' => 'Name',
'rules' => 'required'],
['field' => 'price',
'label' => 'Price',
'rules' => 'numeric'],
['field' => 'description',
'label' => 'Description',
'rules' => 'required']
];
}
public function getAll()
{
return $this->db->get($this->_table)->result();
}
public function getById($id)
{
return $this->db->get_where($this->_table, ["product_id" => $id])->row();
}
public function save()
{
$post = $this->input->post();
$this->product_id = uniqid();
$this->name = $post["name"];
$this->price = $post["price"];
$this->description = $post["description"];
return $this->db->insert($this->_table, $this);
}
public function update()
{
$post = $this->input->post();
$this->product_id = $post["id"];
$this->name = $post["name"];
$this->price = $post["price"];
$this->description = $post["description"];
return $this->db->update($this->_table, $this, array('product_id' => $post['id']));
}
public function delete($id)
{
return $this->db->delete($this->_table, array("product_id" => $id));
}
}
4. Membuat Controller
a. buat file baru di dalam folder application/controllers/admin/ dengan nama Products.php, isi :
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
class Products extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model("product_model");
$this->load->library('form_validation');
}
public function index()
{
$data["products"] = $this->product_model->getAll();
$this->load->view("admin/product/list", $data);
}
public function add()
{
$product = $this->product_model;
$validation = $this->form_validation;
$validation->set_rules($product->rules());
if ($validation->run()) {
$product->save();
$this->session->set_flashdata('success', 'Berhasil disimpan');
}
$this->load->view("admin/product/new_form");
}
public function edit($id = null)
{
if (!isset($id)) redirect('admin/products');
$product = $this->product_model;
$validation = $this->form_validation;
$validation->set_rules($product->rules());
if ($validation->run()) {
$product->update();
$this->session->set_flashdata('success', 'Berhasil disimpan');
}
$data["product"] = $product->getById($id);
if (!$data["product"]) show_404();
$this->load->view("admin/product/edit_form", $data);
}
public function delete($id=null)
{
if (!isset($id)) show_404();
if ($this->product_model->delete($id)) {
redirect(site_url('admin/products'));
}
}
}
defined('BASEPATH') OR exit('No direct script access allowed');
class Products extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model("product_model");
$this->load->library('form_validation');
}
public function index()
{
$data["products"] = $this->product_model->getAll();
$this->load->view("admin/product/list", $data);
}
public function add()
{
$product = $this->product_model;
$validation = $this->form_validation;
$validation->set_rules($product->rules());
if ($validation->run()) {
$product->save();
$this->session->set_flashdata('success', 'Berhasil disimpan');
}
$this->load->view("admin/product/new_form");
}
public function edit($id = null)
{
if (!isset($id)) redirect('admin/products');
$product = $this->product_model;
$validation = $this->form_validation;
$validation->set_rules($product->rules());
if ($validation->run()) {
$product->update();
$this->session->set_flashdata('success', 'Berhasil disimpan');
}
$data["product"] = $product->getById($id);
if (!$data["product"]) show_404();
$this->load->view("admin/product/edit_form", $data);
}
public function delete($id=null)
{
if (!isset($id)) show_404();
if ($this->product_model->delete($id)) {
redirect(site_url('admin/products'));
}
}
}
5. Membuat View
buat tiga macam view :
1. list.php untuk menampilkan data
2. new_form.php untuk menampilkan form tambah data
3. dan edit_form.php untuk menampilkan form edit data
1. list.php untuk menampilkan data
2. new_form.php untuk menampilkan form tambah data
3. dan edit_form.php untuk menampilkan form edit data
