Wiki articles

Todos los que hemos empezado a utilizar Yii para crear aplicaciones Web, nos hemos dado de bruces cuando hemos intentado poner a funcionar el RBAC (acceso de control basado en roles).

ChromePHP is a console logging extension for Google Chrome.

Please, note. This article is entirely based on a work done by me colleague developer, who hasn't got account on this webpage and also hasn't got time for writing this article. I'm writing it for him. I will try to forward him any comments that may appear, but can't assure if/when he'll be able to answer. I'm far, far less experienced in Oracle therefore I won't probably be able to help myself.

In this article I'll try to explain how to use standard quick search fields in CGridView with customized columns.
For example:
We have a record in a database with field switch having 0 or 1 values. After that we want a user to see on or off instead 1 or 0.
So we do the usual thing:

<?php $this->widget('zii.widgets.grid.CGridView', array(
//.....
array(
    'name'=>'...

Yii's by-default directory organization works well enough, but there are several steps one can take that improve the security and serviceability of the system, especially in the context of multiple Yii projects on the same machine (including multiple versions of the same project).

After enabling the Gii module in your protected/config/main.php file and then try to use it with http://example.com/index.php?r=gii, you get an error: ~~~ Error 403 You are not allowed to access this page. ~~~ This is almost certainly caused by the IP filtering mechanism that Gii uses to protect your system from outsiders - by default it allows localhost only (both IPv4 and IPv6), and r...

Yii comes with a set of powerful classes for logging. If you have read the documentation about logging messages, you have noticed that we can actually decide which messages we wish to log. And this is exactly what we are going to do, using [CWebLogRoute](http://www.yiiframework.com/doc/api/1.1/CWebLog...

One can control the detail of a web application in the webroot/index.php file by manipulating the values of YII_DEBUG and YII_TRACE_LEVEL, but these don't appear to be used by console applications. This is because although the base CApplication class defines a displayError() method that does consider these variable, CConsoleApplication overrides it with a function that doesn't honor th...

This very short how-to presents steps required to change controller name. It is oriented for less experienced users, which are starting their journey with Yii, to avoid common newbie pitfalls.

In this short how-to I will show how to customize setFlash() to display messages (flashes) styled to be success confirmation, error report or notice information. And how to achieve displaying errors in other way.

The default behavior with radio button lists is ugly, and I figured out mostly how to style them a coupla different ways. I'll used the blog tutorial example (but with my own posting modes):

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

Un aspecto del diseño de interfaces de usuario tiene que ver con la coherencia del diseño y uso de colores entre los distintos componentes de interfaz de usuario utilizados.

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.

The easiest way to customize look and behaviour of them is to use series of CButtonColumn properties, like: updateButtonImageUrl (path to image for update button), updateButtonLabel (label for the update button; not HTML-encoded), updateButtonOptions (HTML options for this button, used in the way as many htmlOptions property for many widgets) and updateButtonUrl (a PHP expresion th...

Many people want to use downloaded extensions in their own way. As for me most of the extensions require me to correct Yii::import() instructions inside their source code. All these extensions are directory dependent. To avoid the situation described above, I suggest to implement pseudo-anonymous aliases:

// take the curr...

The official Yii project site now supports OpenSearch. This means you can customize your browser's search box to enable direct search of the content in yiiframework.com. For example, by entering a Yii class name in the browser's search box, the corresponding class API page will be shown in the browser.

Often, when writing widgets or editing Yii code, it is unclear whether or not the code is following the MVC pattern.

Trying to learn and help some other programmers to find their solutions on the Yii Forum (I think is a superb way to learn the framework), I was facing one challenge with an external library that a fellow programmer wanted to use -quite good indeed: PHPExcel. And what is PHPExcel?

This article explains issues about installing XAMPP server package (Lite version) on Windows OS and configuring it for serving webapps written in Yii. Please note, that XAMPP is available for many more platforms and systems. I write about Windows edition as it was the only one tested by me.
