Let's see what exactly are the events in Yii!

The only differences in Yii 2 is that its much simpler due to available functions in the Model class for loading and validating models.

It's well known that there are Lazy Loading approach and Eager Loading approach in the relational query. But it's important to note that you should distinguish 2 different modes in the Eager Loading in Yii 1.1.x.

The Yii documentation states:

One aspect of User Interface Design has to do with the coherence of the design and the use of the colors between the different User Interface Components used.

A time ago i've met the issue that Yii doesn't run any client-side form validation when submitting the form by CHtml::ajaxSubmitButton. The small javascript below helps to fix it.

Usually when we use AutoComplete in a project, We need to show "title" or "name" in the list, while when the form is posted, we need some sort of integer ID referring to the selected value. Out of the Box, CJuiAutoComplete widget doesn't provides different display text and post values.

I was wondering how to set-up the application parameters in the back-end to use them all around the application without the need of using the database and I came up with this solution, I hope it helps somebody else.

Note: Please also take a look at the newer EMenu extension. This works even better that the deprecated CDropDownMenu!

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...

Because Yii intends to be integrated nicely with third-party libraries, it does not define any global functions. Everything in Yii needs to be addressed with full class name or object scopes. For example, to access the current user, we need to use Yii::app()->user; to access application parameters, we need Yii::app()->params['name']; and so on. While editors like textmate can help alleviate...

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:

Application configuration determines how an Yii application should behave, because it is the only parameter passed in the entry script. An application, on the other hand, needs to behave differently under different circumstances. For example, an application may need different configurations when running in production mode, development mode and testing mode; In a team development environment, each...

CMenu comes with a lot of great customization options built in but sometimes you need it to do more.
