/**
|
||
|
|
* Class RateitAjax
|
||
|
|
* Contain methods to catch ajax requests and send responses back to the client.
|
||
|
|
*
|
||
|
|
* Description
|
||
|
|
* ```````````
|
||
|
|
*
|
||
|
|
* The usage of the RateitAjax extensions is very easy. The extension provides
|
||
|
|
* the hook $GLOBALS['TL_HOOKS']['rateitAjax'] for extension developers. You
|
||
|
|
* simply have to register your class/method and the extension will call
|
||
|
|
* your class if there is an incomming ajax request.
|
||
|
|
*
|
||
|
|
* You simply have to deside if it's an ajax request for your module and return
|
||
|
|
* the data you want.
|
||
|
|
*
|
||
|
|
* There are a few thinks you should know about the extension:
|
||
|
|
* * YOU have the full controll over the response. That also means
|
||
|
|
* that you have to set the correct header.
|
||
|
|
* * YOU have to terminate the request after you have send the response.
|
||
|
|
* * If the ajax request is not for your method you simply have nothing to
|
||
|
|
* * return.
|
||
|
|
*
|
||
|
|
*
|
||
|
|
* Usage
|
||
|
|
* `````
|
||
|
|
* // config.php
|
||
|
|
* $GLOBALS['TL_HOOKS']['rateitAjax'][] = array('MyClass', 'myMethod');
|
||
|
|
*
|
||
|
|
* // MyClass.php
|
||
|
|
* class MyClass extends System
|
||
|
|
* {
|
||
|
|
* public function myMethod()
|
||
|
|
* {
|
||
|
|
* if ($this->Input->get('acid') == 'myrequest')
|
||
|
|
* {
|
||
|
|
* $arrReturn = array('foo', 'bar', 'foobar');
|
