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.

Splitting the common view content into reusable views


Sometimes, views share the same common portion of content. In the examples made until now, we have seen that a common area for itemsList and itemDetail could be copyright data, which displays a disclaimer about copyright info.

In order to make this, we must put the common content in a separate view and call it using the renderPartial() method of controller (http://www.yiiframework.com/doc-2.0/yii-base-controller.html#renderPartial%28%29-detail). It has the same types of parameters of the render() method; the main difference between the render() and renderPartial() methods is that render() writes a view content in layout and renderPartial() writes only view contents to output.

Example – render partial in view

In this example, we create a common view for both itemsList and itemDetail about copyright data.

Create a view file named _copyright.php in views/news.

Note

Usually, in Yii2's app, a view name that starts with underscore stands for common...
