Tutorial CodeIgniter : Flashdata Highlighting with jQuery and jGrowl

This tutorial explain how to create a notification system based on the jGrowl plugin for jQuery and the CodeIgniter session Flashdata.

Basically, Flashdata are sessions data only available for the next server request and are then automatically removed. This class can easily be used to build a simple notification system for your application.

Step 1: Create a Flashdata

In order to use CodeIgniter flashdata, we need to load the session library. Then, the set_flashdata method allows to set a session flashdata. This code has to be placed in your controller.

	$this->session->set_flashdata('result', 'This is a custom notification using jGrowl and a Flashdata.');

Step 2: Display the Flashdata

I assume that you are using a header view file that is loaded in first everywhere in your application. Just add the code below that test if the flashdata var named result is set, then write the jQuery code that lauch the jGrowl notification.

<?php if ($this->session->flashdata('result') != ''): ?>
	<script type="text/javascript">
	$(document).ready(function() {	
		$.jGrowl("<?php echo $this->session->flashdata('result') ?>");	
<?endif; ?>

Step 3: Install the jGrowl plugin for jQuery

The code above can’t work without adding the JavaScript notification files. You just have to add the jQuery library and the jGrowl plugin files into your header, don’t forget the jGrowl CSS file too. These files can be dowloaded here or on the jGrowl project home page.

Step 4: View demo!

    I was simply trying to find this data for some time. Soon after Six hours with continual Googleing, at
    last I managed to get the idea in your website. I ponder what’s the
    Google’s challenge that will doesn’t get ranking this particular
    educational web sites far better the highest.
    Usually the leading web pages are usually stuffed with junk.
    Primarily just lately, after the brand-new panda algorithm criteria upgrade.
