I’ve completed my latest tutorial, CodeIgniter AJAX with jQuery. Feel free to check it out as well as download the small library that goes along with it Request.

Request is a CodeIgniter library that determines if a request was made via AJAX. This makes it very easy to stick to DRY principles and utilize the same controller methods no matter how a request was initiated.

I haven’t looked at your source, but it sounds pretty cool.  Have you seen the ContextSwitch and AjaxContext helpers contained in the Zend Framework?  You should check them out.

great minds and all…

Buried in Bamboo is ajax_helper.php… which isn’t currently getting used.  Here’s the code

function isAjax()
{
    return isset($_SERVER['HTTP_X_REQUESTED_WITH']) && $_SERVER['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest';
}

Look familiar 😉

If I was going to use it, I’d convert it to use

$this->input->server()

Yeah - it’s a really common way to check if AJAX is the method in which the request was sent. I tried to do a bit of research, to determine which Javascript libraries supported this - as it is a header set by the library itself so it could be easily unsupported - alas, I ran out of time and since I only use jQuery I ran with it for the time being. Just something else to put on my list of to-dos.

Of course, I wouldn’t be surprised if it becomes a standard and FF3 detects the AJAX request and assigns this header from the browser (IE13 will do the same).

It’s not really an API… but, Derek outlines a lot of concerns on his blog and I pretty much agree with those (I made a comment about it as well). It wouldn’t stop me from using the service on a lot of different sites, but if I had something that was absolutely critical to bringing in lots of money - I’d rely on my own hosting for these libraries.

Michael, where’s can I find this tutorial?
Thanks in advance.

Hey Michael, with your site update, this tutorial is online :( I wanted to follow it to figure some things out. Any way of putting it back online?

Michael please put again you old site content available, are a must read for all.

Thanks.

Nice tutorial, but i couldn’t reach it.

Hey Michael

Will you put this great tutorial back on by any chance? As far as I remember it was the best tutor I read regarding CI and AJAX…
