For each column of the CGridView, we can specify name, value, htmlOptions, cssClassExpression etc. In the declarations of the attributes value and cssClassExpression we can use the "special" variable $data, for example like this: 'value'=>'$data->author->username',.
Now we might want to use $data in the declaration of the htmlOptions attribute, which is normally not possible, to generate for example the tag <td id="3" class="name_3">, where 3 is the id of the data model for the current row, i.e. $data->id. That is, we want to be able to use:
Here's a way to accomplish this...
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.
You have a multilingual application, and you want the URL of a page to be different for different languages, to account for SEO. The URL for the contact page for example should look like http://something.com/en/contact in english, and http://something.com/de/contact in german. This tutorial describes how to make it happen.
Note that currently selected language is always a part of the URL, and thus available to the application through $_GET. You don't have to use sessions variables to keep track of the language if you don't want to.
In case of a multilingual application, one might consider it a reasonable approach to store the preferred language of the user in a session variable, and after that, every time a page is requested, to check this session variable and render the page in the indicated language.
This tutorial shows a Yii-way of doing this.
We implement an event handler for the onBeginRequest event; as the name of the event suggests, this event handler will be called at the beginning of each request, so its a good place to check whether a language is provided (via post, session or cookie) and set the application language accordingly.
We also implement a simple Language-Selector Widget, which can render the language options as ajax-links or as a drop-down list.
