大家好！我認為是時候展示 PHP 飛行框架中添加的一些新功能了。今年早些時候，Flight Mike Cao 的原始創建者慷慨地提出將 mikecao/flight 的所有權轉移給一個新的 Flight PHP 組織。自從它被移動以來，我們添加了中間件、路由分組、DIC 和其他功能等功能。這篇文章會有點長，但這只是因為我包含了很多程式碼範例，這樣您就可以了解如何建立部落格的正確上下文。
首先，讓我們解決這個問題。 Flight 是一個帶有一些附加功能的簡單框架。它不會與 Laravel 或 Symfony 或 Yii 或 Cake 或 [填空] 競爭。該框架實際上是針對簡單到中型專案而建造的。它也迎合了那些不喜歡程式碼中難以理解或難以訓練的“魔法”的人。它更適合那些剛開始涉足框架的開發人員，而不是帶有大量隨機包含語句的原始 PHP。
很多很酷的功能，很好的簡單實現，等等等等，這是程式碼。請前往第 2 部分了解精彩內容！
讓我們使用 Composer 來開始這個聚會吧。
要做的第一件事是轉到 app/config/config.php 文件，我們可以在其中放置任何配置，例如 API 金鑰、資料庫憑證和應用程式的其他重要憑證。對於本博客，我們將取消 SQLite 資料庫路徑的 file_path 行的註解：
Flight 現在附帶一個名為 runway 的命令列實用程式。這允許您為 Flight 插件甚至您自己的專案建立自訂命令。
作為骨架的一部分，它附帶了一個 SampleDatabaseCommand，它將為我們正在創建的這個部落格專案提供一個起點。
運行以下命令，它應該會為您填充您的資料庫！
接下來我們將開啟 app/config/services.php 檔案並取消註解 SQLite 行。
為了確保我們已正確設定所有內容，請執行composer start，然後在瀏覽器中造訪http://localhost:8000/。您應該看到以下畫面：
您還會注意到角落裡有一個方便的調試工具欄，其中包含一些自訂的 Flight 面板，可幫助您了解應用程式中發生的情況。如果您將滑鼠懸停在工具列中的各個項目上，您將看到各種懸停，您可以單擊這些懸停以保持頁面上的黏性（稍後會詳細介紹）。
Flight 框架中確實附帶了一個非常基本的 HTML 模板解決方案。這對於非常簡單的網站或只是返回一段簡單的 HTML 來說就很好了。建議使用其他模板平台，例如 Latte、Twig 或 Blade。在本教程中，我們將使用 Latte，因為它非常棒並且沒有依賴項（您會注意到在 Flight 中我們不喜歡不必要的依賴項）！

$ php runway make:record comments
Flight uses the MVC pattern. In order to create a new page you need to define a route in your routes.php file, create a new method in a controller, and then create the HTML file that the browser will serve. You can use runway to help you get started with a new controller class:
php runway make:controller Home
And you should see something similar to the following:
$ php runway make:controller Home Controller successfully created at app/controllers/HomeController.php
If you go to app/controllers/HomeController.php go ahead and add this new method to your HomeController:
/** * Index * * @return void */ public function index(): void { $this->app->render('home.latte', [ 'page_title' => 'Home' ]); }
And create a new file in app/views/home.latte and put in this code:
{extends 'layout.latte'} {block content} My Home Page
{/block}
Finally let's change up the routes to the routes.php file. Go ahead and remove any code in the routes file that begins with $router-> and add a new route for your home router:
$router->get('/', \app\controllers\HomeController::class . '->index');
Make sure you run composer start so that your development server is up. If you go to http://localhost:8000/ in your browser, you should see something like this!
Now we're cookin'!
Let's go ahead and add all the methods in your controller, routes, and html files. Let's start with adding the routes in your routes.php file:
// Blog $router->group('/blog', function(Router $router) { // Posts $router->get('', \app\controllers\PostController::class . '->index'); $router->get('/create', \app\controllers\PostController::class . '->create'); $router->post('', \app\controllers\PostController::class . '->store'); $router->get('/@id', \app\controllers\PostController::class . '->show'); $router->get('/@id/edit', \app\controllers\PostController::class . '->edit'); $router->post('/@id/edit', \app\controllers\PostController::class . '->update'); $router->get('/@id/delete', \app\controllers\PostController::class . '->destroy'); });
So you'll notice we use a group() method here to group all the routes together that start with /blog. We could actually rewrite the routes like the following with the group() method and the same thing would happen:
// Posts $router->get('/blog', \app\controllers\PostController::class . '->index'); $router->get('/blog/create', \app\controllers\PostController::class . '->create');
With the controller, first let's create an empty controller with runway:
php runway make:controller Post
You can copy the code below for your PostController.php:
app = $app; } /** * Index * * @return void */ public function index(): void { $PostRecord = new PostRecord($this->app->db()); $posts = $PostRecord->order('id DESC')->findAll(); $CommentRecord = new CommentRecord($this->app->db()); foreach($posts as &$post) { $post->comments = $CommentRecord->eq('post_id', $post->id)->findAll(); } $this->app->render('posts/index.latte', [ 'page_title' => 'Blog', 'posts' => $posts]); } /** * Create * * @return void */ public function create(): void { $this->app->render('posts/create.latte', [ 'page_title' => 'Create Post']); } /** * Store * * @return void */ public function store(): void { $postData = $this->app->request()->data; $PostRecord = new PostRecord($this->app->db()); $PostRecord->title = $postData->title; $PostRecord->content = $postData->content; $PostRecord->username = $postData->username; $PostRecord->created_at = gmdate('Y-m-d H:i:s'); $PostRecord->updated_at = null; $PostRecord->save(); $this->app->redirect('/blog'); } /** * Show * * @param int $id The ID of the post * @return void */ public function show(int $id): void { $PostRecord = new PostRecord($this->app->db()); $post = $PostRecord->find($id); $CommentRecord = new CommentRecord($this->app->db()); $post->comments = $CommentRecord->eq('post_id', $post->id)->findAll(); $this->app->render('posts/show.latte', [ 'page_title' => $post->title, 'post' => $post]); } /** * Edit * * @param int $id The ID of the post * @return void */ public function edit(int $id): void { $PostRecord = new PostRecord($this->app->db()); $post = $PostRecord->find($id); $this->app->render('posts/edit.latte', [ 'page_title' => 'Update Post', 'post' => $post]); } /** * Update * * @param int $id The ID of the post * @return void */ public function update(int $id): void { $postData = $this->app->request()->data; $PostRecord = new PostRecord($this->app->db()); $PostRecord->find($id); $PostRecord->title = $postData->title; $PostRecord->content = $postData->content; $PostRecord->username = $postData->username; $PostRecord->updated_at = gmdate('Y-m-d H:i:s'); $PostRecord->save(); $this->app->redirect('/blog'); } /** * Destroy * * @param int $id The ID of the post * @return void */ public function destroy(int $id): void { $PostRecord = new PostRecord($this->app->db()); $post = $PostRecord->find($id); $post->delete(); $this->app->redirect('/blog'); } }
Let's kill some time and talk about a few things that are going on in the controller.
First off we are now using our new active record classes:
$PostRecord = new PostRecord($this->app->db()); $posts = $PostRecord->order('id DESC')->findAll();
We are injecting the database we setup in the services.php file above with $this->app->db();. Technically we could also just use Flight::db() as this points to the global $app variable.
Active Record classes are really helpful to simplify interactions with a database. We could rewrite the above in the following code:
$posts = $this->app->db()->fetchAll("SELECT * FROM posts ORDER BY id DESC");
This might not be the best example of how helpful an active record could be. But in part 2 I'll show you some hidden gems inside these classes that make it so much better than writing raw SQL.
Now let's talk HTML files. Here are the files we'll need for the post routes:
app/views/posts/index.latte
{extends '../layout.latte'} {block content} My Amazing Blog
Welcome to my blog!
{foreach $posts as $post} {first} Recent Posts
{/first}
{$post->title}
By: {$post->username} on {$post->created_at|date:'d.m.Y G:i a'}
Comments: {count($post->comments)}
{$post->content|truncate:100}
Update - Delete {/foreach} {/block}
app/views/posts/show.latte
{extends '../layout.latte'} {block content} < Back to blog {$post->title}
Created by: {$post->username} on {$post->created_at|date:'d.m.Y G:i a'}.
{$post->content|breakLines} Last update: {$post->update_at|date:'d.m.Y G:i a'}.
Comments
{foreach $post->comments as $comment} {$comment->username} on {$comment->created_at|date:'d.m.Y G:i a'}.
{$comment->content|breakLines}
Delete {else} No comments yet.
{/foreach} Add comment
{/block}
app/views/posts/create.latte
{extends '../layout.latte'} {block content} Create a Post
{/block}
app/views/posts/edit.latte
{extends '../layout.latte'} {block content} Update a Post
{/block}
Now that we've got all the pieces in place, you should be able to load up your blog page, create a new post, see a post, and delete a post. You may have noticed we've included a comment form but the form doesn't actually work. We can fix that real quick! Let's create a controller with runway:
php runway make:controller Comment
Now you can make the CommentController.php look like the following:
app = $app; } /** * Store * * @param int $id The post ID * * @return void */ public function store(int $id): void { $postData = $this->app->request()->data; $CommentRecord = new CommentRecord($this->app->db()); $CommentRecord->post_id = $id; $CommentRecord->username = $postData->username; $CommentRecord->content = $postData->content; $CommentRecord->created_at = gmdate('Y-m-d H:i:s'); $CommentRecord->updated_at = null; $CommentRecord->save(); $this->app->redirect('/blog/' . $id); } /** * Destroy * * @param int $id The post ID * @param int $comment_id The comment ID * * @return void */ public function destroy(int $id, int $comment_id): void { $CommentRecord = new CommentRecord($this->app->db()); $CommentRecord->find($comment_id); $CommentRecord->delete(); $this->app->redirect('/blog/' . $id); } }
Now let's add a couple other routes in the group chunk of code in routes.php
// Blog $router->group('/blog', function(Router $router) { // Posts // post routes... // Comments $router->post('/@id/comment', \app\controllers\CommentController::class . '->store'); $router->get('/@id/comment/@comment_id/delete', \app\controllers\CommentController::class . '->destroy'); });
With these two additions to the code, you have a fully functioning blog built with Flight! This got the job done and you now have a blog, but the code is somewhat clunky and could be improved to have some pretty nifty features like middleware, permissions, and writing less code! Hop over to part 2
