This is my php code, plain and simple:

Code:

function get_html() {
        echo $this->mdl_gallery->get_gallery_html($this->input->post('id'));
    }

The function just calls a method that creates a bunch of html, based on the id. I simply echo that html, no need for views or so (but you could use them offcourse).[/quote]

Thats how I do it.. but I hate having to echo inside my controller... it doesnt seem to follow the whole purpose of MVC... how exactly would you do it if you wanted to use views?

NachoF, like this:

Code:

function get_html() {
$data['gallery'] = $this->mdl_gallery->get_gallery_html($this->input->post('id'));
}

$this->load->view('page', $data);

A view is in the end nothing more than an echo, only a little more complicated :p

When working with ajax, i tend to go away from mvc and even keep database logic in the controller method... Don't know why, but I like the approach.

Why is the view loaded outside of the function???... that would lead to everytime the controller is called (regardless of which function) that view being loaded, right?

Well, I have been using datamapper library so even though I dont actually do any query I guess in the background my queries are being done in the controller ... but echoing inside a controller is where I draw the line lol
