Is there a way of detecting POST data in URL requests before routing them?

[eluser]sorenchr[/eluser]
I have several routes that only exist because they are 'responses' to ajax POST requests:

Code:

$route['join/register']          = "ajax/join/register";
$route['retrieve/lostpassword']  = "ajax/retrieve/lostpassword";
$route['retrieve/resetpassword'] = "ajax/retrieve/resetpassword";

So I was thinking of something like this(I know it doesn't work but you get the idea):

Code:

if(isset($_POST))
{
  $route['everything'] = "ajax/".theroutehere;
}

Code:

if(isset($_POST))
{
  $route['everything'] = "ajax/".theroutehere;
}

It should work. You can use the ternary operator for more elegant code:

Code:

$route['everything'] = isset($_POST) ? "ajax/".theroutehere : 'controller/method';

but, what doesn't work? Please, could you post some code?

I think you could make this work with a hook, firing before the POST and GET data is sanitized.
Maybe you could do something like this:

- is $_POST populated?
- set a (global) variable $ajax_data to true
- set a (global) variable $ajax_method with the method name
- set a (global) variable $ajax_params with the parameters

then, in the routes.php file, you could set a dynamic route, something like this:

Code:

if($ajax_data) {
  $params = implode('/', $ajax_params);
  $route["$ajax_controller/$ajax_method"] = "ajax/$ajax_method/$params";
}

I've not tested it myself, but I suppose you could give it a shot...

The example was for illustration purposes only, I am quite sure it doesn't work.

I guess this isn't going to be an easy one. Thanks for the help though.

Well, not that hard as it sounds, but maybe you can combine my answer with Cristian's.
Using:

Code:

$route['folder/(:any)'] = "controller/method/$1";

makes it possible to pass as many variables to method as you want (:any can contain /param but also /param/param/param). Now, if you wrap it in a if block, you might be able to prevent the use of hooks:

Code:

if(isset($_POST)) { // or maybe: if($this->input->post('post_name') !== false), but i'm not sure if input is loaded already
    $route['retrieve/(:any)'] = "ajax/retrieve/$1";
    $route['lost/(:any)'] = "ajax/lost/$1";
    // etc
}

That way the route only works when CI gets POST data.

In CodeIgniter 2 the Input Class has $this->input->is_ajax_request().

BTW, $_POST is a superglogal and is always defined so using isset($_POST) wont work. Better to check if its an ajax request. If you use CI2, you can use what kirkaracha told you or simply put this:

Code:

define('IS_AJAX', isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest');

..to application/config/constants.php

With that constant its easy to know if its an ajax request or not.

I tried its working...
