Create PHP MVC application. Sessions. Get all orders
We continue to make our simple php mvc application and today we will add sessions mechanism to our application to avoid access to cabinet main page to unauthorized users. Also we will create method, which will get all orders from database with its detail information.
While preparing for this lesson I have found some problem. Instead of cyrillic data I have got question marks. So you need to set right collation in phpmyadmin (see picture example)
Also in db.php (database configuration file) I made some difference to the code (see code below).
Code lesson (db.php)
<?php
/**
** Класс конфигурации базы данных
*/
class DB{
const USER = "u0016495_cabinet";
const PASS = 123456;
const HOST = "localhost";
const DB = "u0016495_cabinet";
public static function connToDB() {
$user = self::USER;
$pass = self::PASS;
$host = self::HOST;
$db = self::DB;
$conn = new PDO("mysql:dbname=$db;host=$host;charset=UTF8", $user, $pass);
return $conn;
}
}
Code lesson (config.php)
<?php
session_start();
$_SERVER['DOCUMENT_ROOT'] = "/var/www/u0016495/data/www/cabinet.kamil-abzalov.ru";
define("ROOT", $_SERVER['DOCUMENT_ROOT']);
define("CONTROLLER_PATH", ROOT. "/controllers/");
define("MODEL_PATH", ROOT. "/models/");
define("VIEW_PATH", ROOT. "/views/");
require_once("db.php");
require_once("route.php");
require_once MODEL_PATH. 'Model.php';
require_once VIEW_PATH. 'View.php';
require_once CONTROLLER_PATH. 'Controller.php';
Routing::buildRoute();
Code lesson (CabinetController.php)
<?php
class CabinetController extends Controller {
private $pageTpl = "/views/cabinet.tpl.php";
public function __construct() {
$this->model = new CabinetModel();
$this->view = new View();
}
public function index() {
if(!$_SESSION['user']) {
header("Location: /");
}
$this->pageData['title'] = "Кабинет";
$ordersCount = $this->model->getOrdersCount();
$this->pageData['ordersCount'] = $ordersCount;
$productsCount = $this->model->getProductsCount();
$this->pageData['productsCount'] = $productsCount;
$usersCount = $this->model->getUsersCount();
$this->pageData['usersCount'] = $usersCount;
$orders = $this->model->getOrders();
$this->pageData['orders'] = $orders;
$this->view->render($this->pageTpl, $this->pageData);
}
public function logout() {
session_destroy();
header("Location: /");
}
}
Code lesson (CabinetModel.php)
<?php
class CabinetModel extends Model {
public function getOrdersCount() {
$sql = "SELECT COUNT(*) FROM orders";
$stmt = $this->db->prepare($sql);
$stmt->execute();
$res = $stmt->fetchColumn();
return $res;
}
public function getProductsCount() {
$sql = "SELECT COUNT(*) FROM products";
$stmt = $this->db->prepare($sql);
$stmt->execute();
$res = $stmt->fetchColumn();
return $res;
}
public function getUsersCount() {
$sql = "SELECT COUNT(*) FROM users";
$stmt = $this->db->prepare($sql);
$stmt->execute();
$res = $stmt->fetchColumn();
return $res;
}
public function getOrders() {
$sql = "SELECT
orders.id as id,
orders.amount as total,
users.fullName,
users.email
FROM orders
LEFT JOIN users ON users.id = orders.user_id
";
$result = array();
$stmt = $this->db->prepare($sql);
$stmt->execute();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$result[$row['id']] = $row;
}
return $result;
}
