TinyAjax is a small php5 library that allows you to easily add AJAX-functionality to existing pages and create new AJAX-enabled pages with just a few lines of code.
- Put the include/TinyAjax.php and TinyAjaxBehavior.php into system/application/libraries/
- Put the include/TinyAjax.js into the "top-level directory"/js directory
- Put the following code into system/application/init/init_tinyajax.php
<?php if(!defined('BASEPATH')) exit('No direct script access aellowed');
if (!class_exists('TinyAjax'))
{
define('TINYAJAX_PATH', BASEPATH.'application/libraries/');
require_once(TINYAJAX_PATH.'TinyAjax'.EXT);
}
$obj =& get_instance();
$obj->tinyajax = new TinyAjax();
$obj->tinyajax->setScriptPath('../../js');
$obj->tinyajax->setRequestType('post');
?>A simple multiplication example. Here is the Controller.
<?php
class Ajax extends Controller {
function Ajax()
{
parent::Controller();
$this->load->library('tinyajax');
}
function ajax_multiply($x, $y)
{
return $x*$y;
}
function multiply()
{
$this->tinyajax->showLoading();
$this->tinyajax->exportFunction("ajax_multiply", array("first_id", "second_id"), "#third_id", $this);
$this->tinyajax->process();
$this->load->view('ajax_multiply');
}
}
?>And here is the ajax_multiply.php views file:
<html>
<head>
<? $this->tinyajax->drawJavaScript(false,true); ?>
</head>
<body>
Multiply:<br>
<input type="text" id="first_id" value="2"> *
<input type="text" id="second_id" value="3"> =
<input type="text" id="third_id" value="">
<input type="button" value=" * " onclick="ajax_multiply()">
</body>
</html>Add this code to the controller:
function ajax_multiplyb($x, $y)
{
$res = $x * $y;
$res_text = "Multiplying $x and $y results in $res";
$tab = new TinyAjaxBehavior();
$tab->add(TabSetValue::getBehavior("third_id", $res));
$tab->add(TabInnerHtml::getBehavior("result_div", $res_text));
return $tab->getString();
}
function multiplyb()
{
$this->tinyajax->showLoading();
$this->tinyajax->exportFunction("ajax_multiplyb", array("first_id", "second_id"), null, $this);
$this->tinyajax->process();
$this->load->view('ajax_multiplyb');
}And the views file ajax_multiplyb.php look like this:
<html>
<head>
<? $this->tinyajax->drawJavaScript(false,true); ?>
</head>
<body>
Multiply:<br>
<input type="text" id="first_id" value="2"> *
<input type="text" id="second_id" value="3"> =
<input type="text" id="third_id" value="">
<input type="button" value=" * " onclick="ajax_multiplyb()">
<br/>
<div id="result_div"> </div>
</body>
</html>
