CodeIgniter - globally used function

Hightower · 06-28-2009, 01:38 PM

Hi all, I've recently started using CodeIgniter to code my next project, but it's the first time I've used a framework of any sort. My site follows a template using a generic header and footer, so loading a particular page might look like this:

PHP Code:


			
function index()
{
$this->load->view('header');
$this->load->view('index');
$this->load->view('footer');
}

The thing is, within the header file is the HTML code that shows the menu's and stuff, which is the same on each page. Some menu items need stuff working out first, so I did this:

PHP Code:


			
function index()
{
$next_fixture = get_next_fixture()

$this->load->view('header',$next_fixture);
$this->load->view('content');
$this->load->view('footer');
}

private function get_next_fixture()
{
$fixtures = $this->db->get('fixtures');

// Do rest of processing in this function....
// ...
// ...
return $whatever_array;
}

This works a treat, and in my header file I can just echo

PHP Code:

$date_of_fixture

etc wherever I need it in my menu bar.

Ok, now we get on to my problem

This function would need to be called and then passed to the header in each of the files I created. Because the function is to be shown on every page how would I go about making this function be called and displayed in the header view automatically?

I realise I would have to create a seperate file with the function in it, but would this file be a helper? A class??

And then, once I've created this so anything can access it, how would I go about calling it for every page so that the header view can just

PHP Code:

echo $some_variable_that_the_function_created

?

Thanks

I know it's a bit long winded but I've tried to give plenty of info so you guys can help.
