Yii Routing, Active Record and Caching
November 07, 2013 @ 09:37:31

On the SitePoint PHP blog today Sandeep Panda has a new article looking at routing, using Active Record and caching with the Yii Framework. The Yii framework is a " a high-performance PHP framework best for developing Web 2.0 applications".

Almost all modern web apps have 3 major concerns: Retrieving data from a database easily and effectively, caching the web content and URL rewriting to create user friendly URLs. Yii, like any other good framework, offers simple and easy solutions to all of the above. [...] In this tutorial we will look at how Yii greatly simplifies the development of database driven websites with its Active Record support. Additionally, Yii lets you further improve your websites by implementing user friendly URLs and powerful caching techniques.

He creates a simple application based on the Yii framework skeleton called "gadgetstore" that works with fictional phone data. He shows how to set up a few sample routes and adding the "phone" table to the database. He then uses the framework's tools to auto-generate the model and shows the save/delete operations. He then creates the "Phone" controller and an add action to handle the create submissions. Finally, he gets into caching the response data and uses the built-in "cache" function for the models to store the results of a "findAll" request.

Yii Framework Project Joins PHP-FIG
September 17, 2013 @ 12:18:28

According to this recent discussion on the PHP-FIG mailing list, the Yii framework project has tossed their hat into the ring and joined the PHP-FIG.

As Alexander Makarov writes in his post:

I'd like to apply for voting membership because I feel that fig is very important and that I have enough experience to make the final result better.

All of the votes from current members have been "+1" for the project's inclusion into the standards group including ones from several other well-known projects (like Zend Framework, PEAR and Doctrine).

Build a CRUD App with Yii in Minutes
July 03, 2013 @ 10:48:09

On PHPMaster.com there's a new tutorial posted showing you how to create a CRUD app with the Yii framework "in minutes." You might want to have a little familiarity with Yii before you start, but it's not absolutely required.

Yii is a high performance framework that's fast, secure, and well-suited for Web 2.0 applications. It favors convention over configuration, which means that if you follow its guidelines you'll end up writing much less code than you would otherwise (and less code implies fewer bugs). Furthermore, it offers many convenient features out of the box, such as scaffolding, data access objects, theming, access control, caching, and more. In this article I'll cover the basics using Yii to create a CRUD system.

They walk you through a basic installation and jump right in to working with controllers and routing. The rest of the tutorial is broken up into a few different steps:

  • Step 1: Create the database (MySQL in this case)
  • Step 2: Make a model to correspond to the "posts" table
  • Step 3: Click on the CRUD generator for the model

This generates all needed views and functionality to be able to create new records, update current ones, delete records and get the current data.

Yii Framework - Scenarios for Conditional Multiple Validation Rules
April 24, 2012 @ 09:18:49

On the Refulz blog there's a post showing you how to set up conditional multiple validation rules in a Yii framework application.

I am yet to write the last article of the Yii Session series. I just decided to write something about the scenarios in the Validation feature of Yii framework. Scenarios are a very useful tool for adding different validations rules for different cases on the same model. In a real life situation, you would require one validation rule for user registration but the same rule might not be applicable to the User login. Scenarios help you define validation rules for different situations within same model.

He shows you how to set up a "rules()" method in your model and a few validation configurations inside it - ensuring the password and email are set, checking the length of the password, etc. Then, by calling the "validate()" method on the model, you can easily apply these rules and check the pass/fail status.

URL rewriting in Yii to hide index.php
April 20, 2012 @ 09:27:06

In this new post to his blog Gaurish Patil shows users of the Yii framework how they can update their configuration settings to hide the "index.php" in their requests and make cleaner URLs.

Finally we figure out the basics of Yii. While working on basic of Yii, I want to rewrite the url to SEO friendly. So I started to search on google, forum got useful information here http://www.yiiframework.com/doc/guide/1.1/en/topics.url To hide the index.php from url I did changes in config/main.php [...] and I created new .htaccess file in the same directory as my index.php file.

The changes are pretty simple - it's mostly a change to the "urlManager" setting to provide some rules for mapping controller and actions to the right place. The .htaccess file uses Apache's mod_rewrite functionality to grab the requested URL and remap it back to lay on top of the "index.php" front controller for the request.

Under the Hood of Yii's Component Architecture, Part 3
February 14, 2012 @ 09:28:34

PHPMaster.com is back with the third part of their series looking at the internals of the Yii framework (specifically, its components). In this latest article Steven O'Brien focuses on how the framework uses behaviors.

A behavior, as it is called in Yii, is a manner of combining objects at runtime to extend an object's functionality. Behaviors are an excellent way to decouple code and keep ever expanding systems maintainable. [...] We can not reuse our code effectively because PHP doesn't support multiple inheritance. The Yii behavior system is a way of achieving multiple inheritance by implementing mixins.

He gives an example of working with a user that's connecting to your application just to get to a third-party billing system. They show how to take this functionality our of your generic "User" class and make a behavior out of it. This functionality can then be attached to the User object (via an attachBehavior call) and used directly. He gets into how Yii does this magic, showing how it appends it to a special value in the class and the __call method checks the method call to see if it exists in one of these special classes.

Under the Hood of Yii's Component Architecture, Part 2
February 07, 2012 @ 11:53:57

Following up on their previous look at the component architecture of the Yii framework, PHPMaster has posted this new tutorial showing how the framework allows you to do some event-based programming.

An application event is something that occurs which might be of interest to other bits of code. A standard event in most GUI applications would be a "click" event, but the sky's the limit and what events you define is really up to you. [...] The details can be provided by application-specific modules allowing you to keep individual requirements separate from your reusable code. Events allow you to attach a potentially unlimited amount of functionality without changing your core modules and components.

In his example, he shows how to create an event handler that is triggered when the user registers on the site. This event (CEvent) is then registered with the system and is attached via a call in the controller's "init" method.

Under the Hood of Yii's Component Architecture, Part 1
January 31, 2012 @ 11:19:47

On PHPMaster.com today Steven O'Brien takes a look at a popular PHP-based framework, Yii - specifically one of the components that makes it up, the CComponent that provides a base for all other components in the framework.

There's been a lot of buzz surrounding the use of frameworks for quite a while now and there are many great PHP frameworks to choose from. I was blown away by the simplicity and power of the base CComponent class in the Yii framework. [...] Every class in the framework extends from the CComponent class, which means that all subclasses work as components and can raise and handle events as well as be reusable and configurable. This packs a lot of punch for such a little class!

In this first post of the series, he looks at how this base class lets you work with class properties using the magic getters and setters. He includes some code showing how to set them up and how to use it to configure your object by passing in other component and their configuration.

AppBackr Blog:
Automated PHP unit testing for lazy coders
August 02, 2011 @ 10:41:59

In a recent post from the AppBackr blog they share a solution they've found for running unit tests automatically for lazy coders using a combination of PHPUnit, Watchr and Growl notifications (OS X-only, obviously).

Now you could run [your] tests manually after each change by typing 'phpunit ', but we were looking for something a little more comfortable. We want to decrease the transactional cost of running the tests as much as possible to make the lives of our engineers more pleasant. Making testing easy is the only way the engineers will run the tests frequently.

Instead they opted for Watchr, a tool that keeps an eye on a list of files looking for a change. When one happens, a process is fired off - in this case a PHPUnit run. To make it even easier to see feedback, they integrated it with Growl to show pass or fail results. He includes the source for his Watchr script to help you get started.

Introducing the Yii PHP Framework
April 27, 2011 @ 11:03:43

In another in his framework series, Jason Gilmore has a new post on PHPBuilder.com about another popular framework - the Yii framework. He introduces you to the framework and shows the creation of a sample, basic site.

Frameworks have been the topic du jour here at PHPBuilder.com, with numerous recent articles covering DooPHP and Fat-free. In this latest stop on the framework tour, we'll check out Yii, a relatively new framework (less than three years old) that boasts an impressive array of features and an equally impressive array of users, among them the enormously popular Stay.com.

He walks you through the install (downloading the latest version) and shows how to use the command-line tool to automatically generate the basic website structure. He continues on showing how to update the main page and template, how to get it connected to a MySQL database and how to use the Gii tool to create basic admin forms for working with the tables.
