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](http://www.yiiframework.com/doc/api/CAutoComplete) and [jQuery's Autocomplete plugin](http://plugins.jquery.com/project/jq-autocomplete), it's really quite simple.

In overview, assuming that you are looking up and retrieving your data set for the autocomplete widget from a database, there are basically three steps:
[...]
echo $returnVal;
}
       die();
 
 }
```
There are a few things to notice here:
[...]
```php
<?php echo $this->widget('CAutoComplete',
array(
//name of the html field that will be generated
[...]
Take note of the `methodChain` attribute being used. MethodChain essentially appends (or chains) a javascript method to the end of the AutoComplete javascript code that will be generated. This particular method is the `result` method, which fires when an autocomplete item is selected. The code inside of the result function basically references the hidden field that was defined and assigns the 2nd part (part after the pipe) of the selected autocomplete data to that field.

Now that the basics are out of the way, review the documentation for [Yii's CAutoComplete widget](http://www.yiiframework.com/doc/api/CAutoComplete) and [jQuery's Autocomplete plugin](http://plugins.jquery.com/project/jq-autocomplete) to find more ways to customize and use autocomplete functionality in your Yii project.
