Overview of this book

Yii is a high-performance PHP framework best for developing Web 2.0 applications. It provides fast, secure, and professional features to create robust projects, however, this rapid development requires the ability to organize common tasks together to build a complete application. It's all too easy to get confused; this is where this book comes in. This book contains a series of practical project examples for developers starting from scratch. Each section contains the most relevant theories for every topic as you walk through developing each project, focusing on key aspects that commonly confuse users. The book starts with all the framework’s basic concepts, such as controllers and views, to introduce you to Yii and creating your first application, a simple news reader. You will be learn to configure URL rules to make a pretty URL, essential for search engine optimization. Next, you will walk through Model and ActiveRecord, key concepts in database interaction. The second application you will develop is a reservation system that allows you to manage rooms, customers, and reservations. For this, you will use database connection through SQL and ActiveRecord. More complex than the first one, this application will introduce you to the advanced template of Yii 2, splitting the app into two parts: a frontend for all visitors and a backend for the admin. Finally, you will move on to the last two applications: one that allows connections from remote clients, through RESTful components of Yii 2, and another that creates and organizes automatic tasks using the console application structure of Yii 2.

Creating static pages


All websites contain static pages, whose content is static.

To create a static page in a common way, we need to:

  • Create a function (action) to execute action in Controller

  • Create a view for static content

Append the following action to Controller:

public function actionInfo()
{
    return $this->render('info');
}

Then, create a view in views/controller/action-name.php. This procedure is simple but too long and redundant.

Yii2 provides a quick alternative, adding static pages to the actions() method of Controller as follows:

public function actions()
{
  return [
    'pages' => [
    'class' => 'yii\web\ViewAction',
    ],
  ];
}

With this simple declaration, we can put all static content under views/controllerName/pages.

Finally, we can point to the URL with route controller_name/page and the view parameter with the name of a view file such as http://hostname/basic/web/index.php?r=controllerName/pages&view=name_of_view.
