Yii 1.1 Application Development Cookbook

Overview of this book

When Alex told me he was about to write a Yii cookbook about a year ago, I was wondering how original it would be, considering the fact that there was already an online user-contributed cookbook (aka. Yii wiki). It turned out Alex produced a book that is not only full of wisdom about how to use Yii effectively, but also presented in such a systematic way that it can be taken as an essential companion book to the definitive guide to Yii. In fact, Alex has successfully intrigued the interest of every member in the Yii developer team when he asked for review and comments on his newly finished book chapters.As the founder and the lead developer of the Yii framework, I feel this book is a must-read for every Yii programmer. While this book does not describe directly the rules set by Yii, it shows how to program with Yii from a practical perspective. People who are driven by tight project schedules will find this book very handy as it gives ready-to-use solutions to many problems they may face in their projects; people who are already familiar with Yii will also find this book very informative as most problem solutions given in the book can be considered as officially recommended because they have undergone thorough review of every Yii developer team member. Alex, through this book and his active participation in the Yii project, proved himself to be a great programmer as well as a good writer. Qiang XueLead developer of the Yii framework Yii framework is a rapidly growing PHP5 MVC framework often referred to as Rails for PHP.

Applying markdown and HTML


When we create web applications, we will certainly have to deal with creating content. Of course, we can create it with pure text or HTML, but text is often too simple and HTML is too complex and insecure. That is why special markup languages such as BBCode, Textile, and markdown are used.

In this recipe, we will learn how to create a model which will automatically convert markdown to HTML when it is being saved.

Getting ready

  • Create a new application by using yiic webapp as described in the official guide at the following URL:

    http://www.yiiframework.com/doc/guide/en/quickstart.first-app

  • Set up a database connection and create a table named post as follows:

    DROP TABLE IF EXISTS `post`;
    CREATE TABLE IF NOT EXISTS `post` (
       `id` INT(10) UNSIGNED NOT NULL AUTO_INCREMENT,
       `title` VARCHAR(255) NOT NULL,
       `text` TEXT NOT NULL,
       `html` TEXT NOT NULL,
       PRIMARY KEY (`id`)
    );
  • Generate the Post model using Gii
