This is Part 3 of a tutorial on using the Highcharts JS Library with Codeigniter. In this tutorial we look at the Highcharts charting software for JQuery and draw some lovely looking charts by sending data to them from our Codeigniter controller. In this tutorial we update the charts using AJAX and play around with some other features of Highcharts.

I strongly recommend you watch all my videos in full screen mode. It’s the little button on the bottom right of the video. You will be able to see everything much better if you do.

This is Part 4 of a tutorial on Codeigniter. In this tutorial we are going to create a URL shortener app like bitly.

In this part we capture some reporting before we do our short URL redirect.

Here is the source code for the app which is pretty much the starting point ( though I think I actually made a few changes after I saved this and before I did the first tutorial! I walk through those changes though in the first few minutes of the tutorial ).

Hi Everyone!

There have been a few votes on the poll for whether I should post a 6th video in the series. The result was pretty much that Yes I should however I have had a look at the things that I wanted to tell you about to finish off the series and I don’t think they warrant a video.

In a nutshell here are the things I was going to mention:

In the chat controller functions that are called through our AJAX requests it might be worth adding the following line to the start of each of those functions:


if (! $this->input->is_ajax_request())
{
exit();
}


This will prevent anyone from loading the function unless from an AJAX request. I’m not sure if there is any good reason to do this for this app but it’s probably a good idea to get in the practice of checking this.

For the chat you will notice once you have lots of chat in the chat_viewport that you have to always scroll down to see the last message. You could make the following change to have it automatically scroll for you.

Change this line (used in 2 places):


$("div#chat_viewport").html(current_content + data.content);


To:


$("div#chat_viewport").html(current_content + data.content).animate({ scrollTop: $("div#chat_viewport").attr("scrollHeight") }, 1000);


Source Code: Here is the source code for where we finished up if anyone is interested.

In this Codeigniter Tutorial I create a little web based chat application. Users can chat with each other like they would in MSN or IRC etc within your web app. The purpose is to show the approach for creating the app and it also covers JQuery AJAX posting using JSON.

This is Part 5.

Vote! Please have a vote in the poll on the right and let me know if you want to see one more to wrap things up. There are some nice to include additions to round things off etc but only if you guys are interested! Please vote!
