Hi i want to have sth like this:
main_page - controller & view (not cached becouse of login form etc.)
news - controller & view - output (not DB) cached
load news into main_page - controller or directly view - doesn't really matter
How Can i achieve that? Is it possible in clean CI? Use file_get_contents ? or sth simillar? file_get_contents with http ?

1)cheat and use an iframe Smile

2)create a div with an id in your view and use javascript to make a call to the news controller and return the content in the div. jquery is excelent for doing this [url="http://docs.jquery.com/Ajax/jQuery.ajax#options"](http://docs.jquery.com/Ajax/jQuery.ajax#options)[/url]. check out the example code.

Code:
&lt;head&gt;

//put space in script tags so this forum displays them

&lt; script type="text/javascript" src="path/to/jquery.js"&gt;&lt;/ script&gt;

&lt; script type="text/javascript"&gt;

  $.ajax({

    url: "&lt;?=$urlparam?&gt;", 

    dataType: "script",

    cache: false,

    success: function(returndata){

      $('#ajaxout').html(returndata);

    }

  });

&lt;/ script&gt;

&lt;/head&gt;

<div id="ajaxout"></div>

Might be of some help to you or look for HMVC on the forums.

ok use an iframe then Smile

if you want you could move the 'news controller' functionality to a library and then you can just call the library with in your main controller but I am not sure how that affects caching if I am honest.

[edit]
@nmweb.. didn't know that existed cheers

so... when I use clean CI ... think that file_get_contents will be the best method to have some part of the view to be cached and rest not to.
Glad that somebody coded sth like curl_file_get_contents becouse my hosting provider has disabled getting external content via file_get_contents and http Wink

HMVC... maybe with next site Wink

Using file_get_contents in the way you describe is not something I would recommend. It's another http request where it is not necessary. Using output buffering and the Wick library I linked to you should be able to achieve it in a neater and faster way.

First:
Ok mweb this HMVC from Your post is quite simple and good... but I need to get the 'output' into lets say a string and then use it in another controller - the main controller from which other is called via HMVS, anyone know how to do that? Should I just overwrite _output() and put $output into eg $_REQUEST['some_variable_name']?

And the second (solution):
When using gtech method (with jquery || other ajax library, functions) remember to:

header('Content-Type: text/html; charset=iso-8859-2'); //optional, but I have to becouse site is in this encoding and default everything goes utf
header("Cache-Control: no-cache"); // 'a must have' this or/and this one under for IE becouse it cached me the output and every time i saw the login box instead of logged user menu Wink

header("Pragma: no-cache");

Check out Modular Extensions on the forums and wiki. (see my signature)

It will certainly do what you descibe.

The modular extensions is something that is sorely needed as part of the core codeigniter framework. CakePHP uses what's known as components - and it's built for exactly this kind of thing.
