PHP MySql CRUD Dengan Konsep MVC

Pada postingan kali ini saya akan sharing cara membuat CRUD dengan php menggunakan konsep MVC, ok langsung saja buka code editor (saya menggunakan sublime text) dan buat folder baru dengan nama phpmvc didalam folder htdocs kalian dan tambah folder seperti berikut : 

Setelah itu kita siapkan database di mysql, buat database dengan nama phpmvc dan tablenya seperti gambar berikut :

tambahkan file config.php didalam folder app/config :

<?php

define('BASEURL', 'http://localhost:8181/phpmvc/public');
define('DB_HOST', 'localhost');
define('DB_USER', 'root');
define('DB_PASS', '');
define('DB_NAME', 'phpmvc');

kemudian tambahkan 3 file controller didalam folder app/controllers, yaitu Home, About, dan Mahasiswa :

Home.php

<?php

class Home extends Controller {
public function index()
{
$data['nama'] = $this->model('User_model')->getUser();
$data['title'] = 'Halaman Home';

$this->view('templates/header', $data);
$this->view('home/index', $data);
$this->view('templates/footer');
}

}

About.php

<?php

class About extends Controller{

public function index($nama = 'bejo', $pekerjaan = 'guru'){
$data['title'] = 'Halaman About';
$this->view('templates/header', $data);
$this->view('about/index');
$this->view('templates/footer');
}

}

Mahasiswa.php

<?php

class Mahasiswa extends Controller {
public function index(){
$data['title'] = 'Data Mahasiswa';
$data['mhs'] = $this->model('Mahasiswa_model')->getAllMhasiswa();
$this->view('templates/header', $data);
$this->view('mahasiswa/index', $data);
$this->view('templates/header');
}

public function detail($id){

$data['title'] = 'Detail Mahasiswa';
$data['mhs'] = $this->model('Mahasiswa_model')->getAllMhasiswaById($id);
$this->view('templates/header', $data);
$this->view('mahasiswa/detail', $data);
$this->view('templates/header');
}

public function edit($id){

$data['title'] = 'Detail Mahasiswa';
$data['mhs'] = $this->model('Mahasiswa_model')->getAllMhasiswaById($id);
$this->view('templates/header', $data);
$this->view('mahasiswa/edit', $data);
$this->view('templates/header');
}

public function tambah(){
$data['title'] = 'Tambah Mahasiswa';
$this->view('templates/header', $data);
$this->view('mahasiswa/tambah');
$this->view('templates/header');
}

public function simpanmahasiswa(){
$nim     = $_POST['nim'];
$nama    = $_POST['nama'];
$jurusan = $_POST['jurusan'];
$data['mhs'] = $this->model('Mahasiswa_model')->tambahMahasiswa($nim,$nama,$jurusan);
// return $this->index();
header('location:../mahasiswa');
}

public function updateMahasiswa(){
$nim     = $_POST['nim'];
$nama    = $_POST['nama'];
$jurusan = $_POST['jurusan'];
$data['mhs'] = $this->model('Mahasiswa_model')->updateMahasiswa($nim,$nama,$jurusan);
// return $this->index();
header('location:../mahasiswa');
}

public function hapus($id){
$data['mhs'] = $this->model('Mahasiswa_model')->deleteMhs($id);
// return $this->index();
header('location:../../mahasiswa');
}
}

Tambah 3 file didalam folder app/core : App.php, Controller.php, Database.php

App.php

<?php

class App{

protected $controller = 'Home';
protected $method = 'index';
protected $params = [];

public function __construct(){
$url = $this->parseURL();

if(file_exists('../app/controllers/' . $url[0] . '.php')){
$this->controller = $url[0];
unset($url[0]);
}

require_once '../app/controllers/' . $this->controller . '.php';
$this->controller = new $this->controller;

if(isset($url[1])){
if(method_exists($this->controller, $url[1])){
$this->method = $url[1];
unset($url[1]);
}
}

if(!empty($url)){
$this->params = array_values($url);
}

//jalankan controller
call_user_func_array([$this->controller, $this->method], $this->params);
}

public function parseURL(){
if( isset($_GET['url'])){
$url = rtrim($_GET['url'], '/');
$url = filter_var($url, FILTER_SANITIZE_URL);
$url = explode('/',$url);
return $url;
}
}

}

Controller.php

<?php

class Controller{
public function view($view, $data = [])
{
require_once '../app/views/' . $view . '.php';
}

public function model($model)
{
require_once '../app/models/' . $model . '.php';
return new $model;
}

}

Database.php

<?php

class Database{
private $host = DB_HOST;
private $user = DB_USER;
private $pass = DB_PASS;
private $dbnm = DB_NAME;

private $dbh;
private $stmt;

public function __construct()
{
$dsn = 'mysql:host='. $this->host .';dbname='. $this->dbnm;

$option = [
PDO::ATTR_PERSISTENT => true,
PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
];

try{
$this->dbh = new PDO($dsn,$this->user,$this->pass, $option);
}catch(PDOException $e){
die($e->getMessage());
}
}


public function query($query)
{
$this->stmt = $this->dbh->prepare($query);
}

public function bind($param, $value, $type = null){
if(is_null($type)){
switch (true) {
case is_int($value):
$type = PDO::PARAM_INT;
break;
case is_bool($value):
$type = PDO::PARAM_BOOL;
break;
case is_null($value):
$type = PDO::PARAM_NULL;
break;
default:
$type = PDO::PARAM_STR;
}
}

$this->stmt->bindValue($param, $value, $type);
}

public function execute()
{
$this->stmt->execute();
}

public function resultSet()
{
$this->execute();
return $this->stmt->fetchAll(PDO::FETCH_ASSOC);
}

public function single()
{
$this->execute();
return $this->stmt->fetch(PDO::FETCH_ASSOC);
}
}



tambahkan model didalam folder models : Mahasiswa_model.php

<?php

class Mahasiswa_model{

private $table = 'mahasiswa';
private $db;

public function __construct()
{
$this->db = new Database;
}

public function getAllMhasiswa()
{
$this->db->query('SELECT * FROM ' . $this->table);
return $this->db->resultSet();
}

public function getAllMhasiswaById($id)
{
$this->db->query('SELECT * FROM ' . $this->table . ' WHERE id=:id');
$this->db->bind('id',$id);
return $this->db->single();
}

public function tambahMahasiswa($nim, $nama, $jurusan)
{
$this->db->query('INSERT INTO ' . $this->table . '(nim, nama, jurusan) VALUES(:nim, :nama, :jurusan)');
$this->db->bind('nim',$nim);
$this->db->bind('nama',$nama);
$this->db->bind('jurusan',$jurusan);
$this->db->execute();
}

public function updateMahasiswa($nim, $nama, $jurusan)
{
$this->db->query('UPDATE ' . $this->table . ' SET nama=:nama, jurusan=:jurusan WHERE nim=:nim');
$this->db->bind('nim',$nim);
$this->db->bind('nama',$nama);
$this->db->bind('jurusan',$jurusan);
$this->db->execute();
}

public function deleteMhs($id)
{
$this->db->query('DELETE FROM ' . $this->table . ' WHERE id=:id');
$this->db->bind('id',$id);
$this->db->execute();
}

}

didalam folder view tambahkan folder untuk masing-masing controller yaitu : folder home, about, mahasiswa dan satu foder tambahan yaitu templates 
didalam folder templates tambahkan dua file : header.php dan footer.php

header.php

<!DOCTYPE html>
<html>
<head>

<link rel="stylesheet" href="<?= BASEURL; ?>/css/bootstrap.css">
</head>
<body>
<nav class="navbar navbar-expand-lg navbar-light bg-light">
<div class="container">
  <a class="navbar-brand" href="<?= BASEURL; ?>">Toekang Ketik</a>
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarNavAltMarkup" aria-controls="navbarNavAltMarkup" aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbarNavAltMarkup">
    <div class="navbar-nav">
      <!-- <a class="nav-item nav-link active" href="<?= BASEURL; ?>">Home <span class="sr-only">(current)</span></a> -->
      <a class="nav-item nav-link" href="<?= BASEURL; ?>/mahasiswa">Mahasiswa</a>

<h1 class="display-4">Belajar PHP MVC</h1>
<p class="lead">This is a simple hero unit, a simple jumbotron-style component for calling extra attention to featured content or information.</p>
<hr class="my-4">
<p>It uses utility classes for typography and spacing to space content out within the larger container.</p>
