ZendFramework 2 Demo Application

Introduction

This started as a simple ZF2 demo login/logout (with access control) application example. But, it has been expanded with other features. A live example is available at http://zf2demo-tshikaaa.rhcloud.com/.

The Symfony2 version of this demo application is available here.

Assuming PHP 5.4.0 (or higher) is installed on your PC, you can also clone this application locally and start it with the following command from the root directory:

C:\php\php.exe -S localhost:8000 -t public

General Structure

The structure of the code is based on the ZF2 skeleton application. However, the Application module has been replaced with a Main module.

• The code contains explanatory comments not mentioned here.
• Controllers depending on services are created with factories.
• The index controller handles the home page.

Login/Logout & Access Control

A login system with access control has been implemented without the use of a database. The login form is available on the home page and is displayed with the help of a view helper called LoginWidget.

Two controllers, three services and one model have been created:

• The authentication controller deals with login (i.e. authentication) and logout requests.
• The access controller makes sure proper roles are owned to access restricted pages.
• The authentication adaptor checks usernames and passwords, and assign roles.
• The user session storage service stores session information between HTTP requests.
• The login/logout service is the mediator between the authentication controller, the access controller, the authentication adapator and the user session service.
• The user model is helps creating creating the login form.

This code is remotely inspired from Samsonasik's code example. It has been significantly refactored and extended.

Roll A Dice Service

In order to demonstrate the use of a roundtrip and of Ajax to call a service, a roll-a-dice service has been implemented.

• The roll-a-dice controller handles request to the service.
• The roll-a-dice service provides a random number between 1 and 6.

Both means to throw a dice are available in the corresponding service page which contains some Javascript using JQuery.

Persistence With Doctrine ORM

Three entities have been created: Client, Order and OrderLine. There is a one-to-many relationship between clients and orders, and another one-to-many relationship between orders and order lines. Some basic functionalities to add or delete entities have been implemented too.

A local SQLite3 database called demo.db is created (if missing) to persist data.

Testing

Some PHP unit tests for controllers and the roll-a-dice service have been implemented. They do not cover all code.
