As seen in this post, Yii doesn't enforce how language is set and maintained within the session.

Have you ever wanted to use an auto-complete field to look up a user or some other data, but want the database ID of that user or data returned as well so that you can more easily perform some function when the form is submitted? Thanks to Yii's CAutoComplete widget and [jQuery's Autocomplete plugin](http://plugins.jquery.com/project/jq-autocomp...

Often you'll need a form with two dropdowns, and one dropdown's values will be dependent on the value of the other dropdown. Using Yii's built-in AJAX functionality you can create such a dropdown.

Here's a simple way to create a breadcrumb widget to be used in your templates. The idea is just to isolate how the breadcrumb is generated based on an array of crumbs.

In a Web application, we often need to display pages like "about this site", "legal information", whose content are mostly static. There are several approaches to deal with this kind of pages.

Set your messages in a controller:

Yii::app()->user->setFlash('success', "Data1 saved!");
Yii::app()->user->setFlash('error', "Data2 failed!");
Yii::app()->user->setFlash('notice', "Data3 ignored.");

Web feed is a data format used for providing users with frequently updated content. In this article, we describe how to use Zend_Feed, an excellent component from Zend Framework to generate Web feed for an Yii application. This article can also serve as a general guide...

Assume we want to use a single HTML form to collect input for both model A and model B, and we want to display input errors (if any) in the same error summary box. We can define the following action code:

Yii core messages refer to static text strings in the core Yii framework code which are meant to be displayed to end-users (e.g. core exception messages, default validation error messages). Customization of these core messages is needed in two circumstances:

According to the manual http://jp.php.net/manual/en/memcache.installation.php;

To fix issues with display of special language characters once and for all there's a solution: use Unicode UTF-8 everywhere. If everything is set up to use Unicode, you can use mostly every language in your application.

This behavior will automatically set timestamp fields to the row creation and modification times.

Since PHP is dynamically typed language, the way IDE may help you is limited.

A dropdown list can be used to select a value, based on which we can filter the data to be displayed. For example, the extension page has a dropdown list to filter the displayed extensions according to the selected category.

There are many ways to automate the setting of timestamps in yii ActiveRecord models. Three are presented here:

A simple and effective way to keep track what your users are doing within your application is to log their activities related to database modifications. You can log whenever a record was inserted, changed or deleted, and also when and by which user this was done. For a [CActiveRecord] Model you could use a behavior for this purpose. This way you will be able to add log functionality to ActiveRecor...

Here is a way to dynamically extend tabs based on clips.
Probably even more complex things could be done.

Some PHP installations may use a different php.ini file for CLI PHP (command line PHP parser). As a result, when running the model or crud command in yiic shell, you may encounter errors like "YiiBase::include(PDO.php): failed to open stream..." or "...could not find driver", even though the requirement checker confirms you have PDO and the corresponding database driver.
