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.

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.

"By Example" cookbook pages will provide coding examples for many of the commonly used classes within Yii. We will try to provide as many usage examples as possible for keep these pages as helpful as possible.

The easiest way to update content in AJAX is to use the renderPartial method.

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).

Hello ppl. Even though i have a small experience with yii I though of writing this to help people which want to do something similar.

Often happens to have the need of change a part of the page with ajax.

In this tutorial we will learn how to realize a create interface using a dialog.

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

'dataProvider' => $dataprovider,
'id'=>'recipient_table',
    'selectionChanged'=>'updateEditForm',
'columns' => array(
	'rec_id',
            'org.nachname',
            'org.vorname',
            'org_id',
            array(
                'class'=>'CButtonColumn',
                'template'=>'{...

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'm developing a website that has an option to look up a car's registration number via SOAP and return additional details such as make, model, colour etc.

This tutorial shows how to filter CListView items by AJAX, and it's compatible with disabled JavaScript users
In my case this has been done to filter users list

This tutorial will show you how to create Ajax dialog which allows to create new model, update or delete existing model. It works with simple links, CGridView button column links, adds a minimal amount of code and degrades gracefully with JavaScript turned off.

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

The only thing required is simple, we just need to create a view that will be partially rendered by a call to a controller (using renderPartial) and make sure that we process output -setting to true the parameter on the function. Everything will work as expected but...

This solution requires Yii 1.1.9 or above

Many desktop programmers are used to having dynamic forms, where clicking on a record in a parent sub-form, updates another sub-form with the child records. While having many levels of nested sub-forms in a single view might not be such a good idea for a web application, I thought doing it one level deep might be interesting and useful. But, instead of sub-forms I used CGridViews.

Sometimes you want to render a view in Fancybox.
