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.

Multiple grids on one page


Every Yii2 widget has so much encapsulated in it that using multiple GridView widgets is a simple activity that involves making few changes.

The only parameters indeed that are not customizable with the DataProvider model class are pageParam and sortParam, which define the current page index and the parameters used to order a grid.

Suppose, for example, that we have two GridViews filled with two different data providers, $firstDataProvider and $secondDataProvider.

In the controller, we will set the pageParam and sortParam parameters of each DataProvider:

$firstDataProvider->pagination->pageParam = 'first-dp-page';
$firstDataProvider->sort->sortParam = 'first-dp-sort';

$secondDataProvider->pagination->pageParam = 'second-dp-page';
$secondDataProvider->sort->sortParam = 'second-dp-sort';

If we miss these definitions when changing a page or sorting a column, this action will also affect the other GridView in the same page because we have not distinguished...
