hi guys, Here I'm going to give you a working example of ajax form submiting in Yii.

This example uses a MySQL DB with a table named tree with the fields id, name, and parent_id. The parent_id will be NULL for root elements. The SQL is kept simple (no autoinc, no FK, etc).

With yii you're able to create ajax requests and updates easily. But most times you always want to show a loading indicatior to your user.

With Yii you can use one CActiveForm for collecting data for two or more models with ajax validation and client validation.

Since I used CGridView for a first time, I didn't like how it handled operations like sorting, filtering, changing page and etc using AJAX.

I have a CGridView with a list of clients/events. For each row (EventClient) I wanted a quick edit dialog.

As I'm new to the framework (2 weeks) - I tried to build a functionallity I already use a lot in my old framework (PRADO). This means combining a GridView with a form. And this in one page, what allows you to select a record from the grid and view the values in the same page without jumping to a new page.

Sometimes new Yii guys face problem to manage dependent dropDownList using AJAX. I am going to discuss an easy solution about this issue.

In doing internet searches trying to learn how to incorporated ajax into web pages generated by the yii framework I noticed that there seems to be a lot of confusion. I worry that too-clever hacks will be broken in upgrades of the framework.
