Query string enabled and possible bug with current_url

[eluser]Jelenik[/eluser]
Hi all,

i had to enable query strings because i am using new version of jquery for ajax calls which return data in json. Jquery allways appends url of request with ?callback=..... so all of my ajax functions in controller were unaccessible until i enabled query strings.

But now when i use current_url - it adds question mark before uri segments. For example:
real url adress in browser: "http://localhost/test/something"
adress shown via current_url(): "http://localhost/?/test/something"

When i turning on that query string support i didnt expected that it will affect some functions - so i dont know if this behaviour is OK, or it is a bug?

Jquery allways appends url of request with ?callback=.

Not sure what you meant by this, but you can simply use

Code:

var url = "<?=base_url()?>index.php/controller/function/";
        $.post(url,
        {  'param': some_id },
                function(data)
                {
                  //this will be your call back which will be executed

                },'json'
        );

And why you activate query strings, if you just need to fetch $_GET var? Actually you could get the same result, by doing something like this...

Code:

// In your controller
$callback = $this->input->get('callback') ? $this->input->get('callback') : '';

Yes Artharva - i know how send post call I am saying that with your example jquery will add to var url ?callback=Jquery.... if you want or dont want. You can read more about that here: http://www.victorocastro.com/2011/02/26/...t-the-219/

Thanks toopay - i didnt know that i can access get variables without enabling query strings. So i have disabled them and i had to set $config['uri_protocol'] to PATH_INFO - when i had AUTO - all ajax calls with ?callback=Jquery.... on the end of url were served from main controller and not from right controller.

Ok, so i figure it out thanks you guys to have query string disabled.

But is that behaviour of current_url right when query string is enabled?

'?' after index.php, yep.

I came across this problem today. So is CI simply incompatible with jQuery's native get/post methods? $.get/.post, because of query strings?

It'd be a lot easier to be able to simply pass an argument to a controller method without all this hoopla.

You need only to change this:

Code:

$config['uri_protocol'] = 'AUTO'

to this

Code:

$config['uri_protocol'] = 'PATH_INFO';

You don't need to enable query strings.
You can get variables from jquery ajax calls via post, or get:

Code:

$something = $this->input->post('something');
$something = $this->input->get('something');

Hope it helps - its working for me this way.
