Dalam tutorial ini, kami akan mencipta aplikasi TodoList yang berfungsi menggunakan Lithe. Anda akan belajar cara menstruktur projek anda, mencipta paparan interaktif dan melaksanakan API RESTful untuk mengurus tugas anda. Projek ini akan menjadi contoh terbaik tentang cara membina aplikasi web moden dengan PHP.
Mula-mula, mari buat projek Lithe baharu:
composer create-project lithephp/lithephp todo-app cd todo-app
Edit fail .env dalam akar projek dengan tetapan berikut:
DB_CONNECTION_METHOD=mysqli DB_CONNECTION=mysql DB_HOST=localhost DB_NAME=lithe_todos DB_USERNAME=root DB_PASSWORD= DB_SHOULD_INITIATE=true
Jalankan arahan untuk mencipta migrasi baharu:
php line make:migration CreateTodosTable
Edit fail migrasi yang dihasilkan dalam src/database/migrations/:
return new class { public function up(mysqli $db): void { $query = " CREATE TABLE IF NOT EXISTS todos ( id INT(11) AUTO_INCREMENT PRIMARY KEY, title VARCHAR(255) NOT NULL, completed BOOLEAN DEFAULT FALSE, created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP, updated_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP ON UPDATE CURRENT_TIMESTAMP ) "; $db->query($query); } public function down(mysqli $db): void { $query = "DROP TABLE IF EXISTS todos"; $db->query($query); } };
Jalankan migrasi:
php line migrate
Jana model baharu:
php line make:model Todo
Edit fail src/models/Todo.php:
namespace App\Models; use Lithe\Database\Manager as DB; class Todo { public static function all(): array { return DB::connection() ->query("SELECT * FROM todos ORDER BY created_at DESC") ->fetch_all(MYSQLI_ASSOC); } public static function create(array $data): ?array { $stmt = DB::connection()->prepare( "INSERT INTO todos (title, completed) VALUES (?, ?)" ); $completed = false; $stmt->bind_param('si', $data['title'], $completed); $success = $stmt->execute(); if ($success) { $id = $stmt->insert_id; return [ 'id' => $id, 'title' => $data['title'], 'completed' => $completed ]; } return null; } public static function update(int $id, array $data): bool { $stmt = DB::connection()->prepare( "UPDATE todos SET completed = ? WHERE id = ?" ); $stmt->bind_param('ii', $data['completed'], $id); return $stmt->execute(); } public static function delete(int $id): bool { $stmt = DB::connection()->prepare("DELETE FROM todos WHERE id = ?"); $stmt->bind_param('i', $id); return $stmt->execute(); } }
Jana pengawal baharu:
php line make:controller TodoController
Edit fail src/http/controllers/TodoController.php:
namespace App\Http\Controllers; use App\Models\Todo; use Lithe\Http\Request; use Lithe\Http\Response; class TodoController { public static function index(Request $req, Response $res) { return $res->view('todo.index'); } public static function list(Request $req, Response $res) { $todos = Todo::all(); return $res->json($todos); } public static function store(Request $req, Response $res) { $data = (array) $req->body(); $todo = Todo::create($data); $success = $todo ? true : false; return $res->json([ 'success' => $success, 'message' => $success ? 'Tarefa criada com sucesso' : 'Falha ao criar tarefa', 'todo' => $todo ]); } public static function update(Request $req, Response $res) { $id = $req->param('id'); $data = (array) $req->body(); $success = Todo::update($id, $data); return $res->json([ 'success' => $success, 'message' => $success ? 'Tarefa atualizada com sucesso' : 'Falha ao atualizar tarefa' ]); } public static function delete(Request $req, Response $res) { $id = $req->param('id'); $success = Todo::delete($id); return $res->json([ 'success' => $success, 'message' => $success ? 'Tarefa removida com sucesso' : 'Falha ao remover tarefa' ]); } }
Buat direktori src/views/todo dan tambah fail index.php:
<!DOCTYPE html> <html> <head> <title>TodoList com Lithe</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <style> * { margin: 0; padding: 0; box-sizing: border-box; font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, sans-serif; } body { min-height: 100vh; background-color: #ffffff; padding: 20px; } .container { max-width: 680px; margin: 0 auto; padding: 40px 20px; } h1 { color: #1d1d1f; font-size: 34px; font-weight: 700; margin-bottom: 30px; } .todo-form { display: flex; gap: 12px; margin-bottom: 30px; border-bottom: 1px solid #e5e5e7; padding-bottom: 30px; } .todo-input { flex: 1; padding: 12px 16px; font-size: 17px; border: 1px solid #e5e5e7; border-radius: 10px; background-color: #f5f5f7; transition: all 0.2s; } .todo-input:focus { outline: none; background-color: #ffffff; border-color: #0071e3; } .add-button { padding: 12px 20px; background: #0071e3; color: white; border: none; border-radius: 10px; font-size: 15px; font-weight: 500; cursor: pointer; transition: all 0.2s; } .add-button:hover { background: #0077ED; } .todo-list { list-style: none; } .todo-item { display: flex; align-items: center; padding: 16px; border-radius: 10px; margin-bottom: 8px; transition: background-color 0.2s; } .todo-item:hover { background-color: #f5f5f7; } .todo-checkbox { width: 22px; height: 22px; margin-right: 15px; cursor: pointer; } .todo-text { flex: 1; font-size: 17px; color: #1d1d1f; } .completed { color: #86868b; text-decoration: line-through; } .delete-button { padding: 8px 12px; background: none; color: #86868b; border: none; border-radius: 6px; font-size: 15px; cursor: pointer; opacity: 0; transition: all 0.2s; } .todo-item:hover .delete-button { opacity: 1; } .delete-button:hover { background: #f5f5f7; color: #ff3b30; } .loading { text-align: center; padding: 20px; color: #86868b; } .error { color: #ff3b30; text-align: center; padding: 20px; } </style> </head> <body> <div> <h2> Configurando as Rotas </h2> <p>Atualize o arquivo src/App.php para incluir as rotas da TodoList:<br> </p> <pre class="brush:php;toolbar:false">use App\Http\Controllers\TodoController; $app = new \Lithe\App; // Rota para a página principal $app->get('/', [TodoController::class, 'index']); // Rotas da API $app->get('/todos/list', [TodoController::class, 'list']); $app->post('/todos', [TodoController::class, 'store']); $app->put('/todos/:id', [TodoController::class, 'update']); $app->delete('/todos/:id', [TodoController::class, 'delete']); $app->listen();
Untuk memulakan pelayan pembangunan, jalankan:
php line serve
Pergi ke http://localhost:8000 dalam penyemak imbas anda untuk melihat aplikasi sedang beroperasi.
TodoList kami mempunyai ciri-ciri berikut:
Anda kini mempunyai aplikasi TodoList berfungsi sepenuhnya yang dibina dengan Lithe. Contoh ini menunjukkan cara membuat aplikasi web moden dengan PHP, termasuk:
