PHP
In the third part of this tutorial, we will add routes to our application and finally, we will set the default file.
Add routes
Next, inside the file index.php, we add routes to fetch events, and categories, and register login and logout users.
<?php
//autoloading classes
require_once __DIR__.'/vendor/autoload.php';
//fix cross origin blocked
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Methods: GET, POST, OPTIONS");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
header('Content-Type: application/json');
$method = $_SERVER['REQUEST_METHOD'];
if ($method == "OPTIONS") {
header('Access-Control-Allow-Origin: *');
header("Access-Control-Allow-Headers: X-API-KEY, Origin, X-Requested-With, Content-Type, Accept, Access-Control-Request-Method,Access-Control-Request-Headers, Authorization");
header("HTTP/1.1 200 OK");
die();
}
//events actions
use App\Controllers\EventController as EventController;
$event = new EventController;
//categories actions
use App\Controllers\CategoryController as CategoryController;
$category = new CategoryController;
//user actions
use App\Controllers\UserController as UserController;
$user = new UserController;
//break url to parts
$segments = explode("/", parse_url($_SERVER['REQUEST_URI'], PHP_URL_PATH));
if($_SERVER['REQUEST_METHOD'] === 'GET' && empty($segments[1])) {
$event->index();
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'GET' && $segments[1] === 'events' && empty($segments[2])) {
$event->index();
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'GET' && $segments[1] === 'event' && isset($segments[2])) {
$event->show($segments[2]);
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'GET' && $segments[1] === 'events' && isset($segments[2]) && $segments[2] === 'category' && isset($segments[3])) {
$event->eventsByCategory($segments[3]);
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'GET' && $segments[1] === 'categories' && empty($segments[2])) {
$category->index();
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'POST' && $segments[1] === 'register' && empty($segments[2])) {
$data = (array) json_decode(file_get_contents('php://input'), true);
$user->register($data);
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'POST' && $segments[1] === 'login' && empty($segments[2])) {
$data = (array) json_decode(file_get_contents('php://input'), true);
$user->login($data);
exit;
}else if($_SERVER['REQUEST_METHOD'] === 'POST' && $segments[1] === 'logout' && empty($segments[2])) {
$data = (array) json_decode(file_get_contents('php://input'), true);
$data['api_key'] = $_SERVER['HTTP_X_API_KEY'] ?? '';
$user->logout($data);
exit;
}else {
http_response_code(404);
echo json_encode([
'error' => true,
'message' => 'The page you are looking for does not exist.'
]);
}
Set index.php as default
Next, to set index.php as default once the user visits our app add the following code inside the file .htaccess.
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule . index.php [L]
