Codeigniter and AJAX - Cross Server Scripting Issues

[eluser]lanzd[/eluser]
I'm trying to use AJAX in my CI application and am running into some issues with my requests being flagged as Cross Server Scripting (CSS).

I have links which without Javascript enabled they will follow through the link and work fine. When I try to intercept the click event I am basing my AJAX request URL off of the href of the link.

After rendering the URL would be something like:

Code:

http://mywebsite.com/page/method

The issue with this is that my requests sometimes return a 500 not found error. Since this is only happening sometimes I believe this is due to being flagged as CSS.

If I omit the base_url() from my href then all of my requests would look like:

Code:

http://mywebsite.com/page/method/destination-page/destination-method

When I am really trying to get to:

Code:

http://mywebsite.com/destination-page/destination-method

I'm sure there is a simple way to by pass this, I'm just not aware of it. Everywhere I looked they seem to use one of either way or sometimes site_url() instead of base_url();

Can someone shed some insight on this?

I found something in my code which was causing the issue. So this issue was not due to CSS.

However I have had issues with it in the past and remember I had found this bit of code which uses the CSRF cookie CI automatically generates (if enabled). I do not remember where I found it so I cannot provide a link.

Code:

$(document).ready(function(){
    $(function($) {

        // this bit needs to be loaded on every page where an ajax POST may happen
        $.ajaxSetup({
            data: {
                csrf_prot: $.cookie('csrf_prot')
            }
        });
    });
});

That just has to be included on any page which may make a AJAX request and it should prevent any CSS issues.

Note: You need jQuery cookie in order for this to work: https://github.com/carhartl/jquery-cookie


Sorry for this journal of mine, I would have deleted the entire thread but did not see an option. If an admin sees this it can be deleted. Many Thanks!
