Codeigniter pagination conceptual problem

I have a page /discussion and I want to implement pagination in it. Now, I want that for the first time the page should load as /discussion, which means that this act as if it was /discussion/page/1. For the other page the url will be /discussion/page/$pagenumber.

Now, the problem is index(). Normally, I initialize all the page data in the index() and then load the view with the initialized data. But, here I’ll have to initialize default page stuff in index() and then the pagination stuff in page(). So, is there a way of sending another set of data from page() to the view? I don’t want to load the view since it will be loaded by the index().

However, I think it is not possible to do what I mentioned above. So, maybe I should keep my index() empty and do all the initialization in the page() and then load the view there. What do you say?

I'm not quite sure what your problem is.

If you have a index() method you can set all the pagination information there, remember you have to tell the pagination library which uri segment will be using to get the page number, and that doesn't have anything to do with the index().

There is no page() method in the controller, all of the pages are the same index() with a different set of paginated data, given by the uri_segment defined as the page number, that means all the stuff that is not related to the paginated queryset are intact through the pages.

You don't need both the "page" and "index" methods, just use a route.

Using an index() method and dropping the page() method:

$route['discussion/page/(:num)'] = 'discussion/index/$1';

/discussion still gives you page 1, requesting discussion/page/32 will map to discussion/index/32

This assumes you're grabbing the page number as an argument (url segment), like so:

function index ($page = 1) {}

If you are doing something else, a route is still appropriate, maybe just not the one provided.

It sounds like you're trying to have your page method decorate your index method. Without knowing more about the overall structure of the controller, there really isn't terribly much to say, but it sounds like the below will help:

function page( $pos )
{
    $this->index( $pos );
}

// a default parameter lets you ensure that this does not neet to have a page set.
function index( $pos = 0 )
{
   // when calling the DB (I'm guessing that is where the pagination really happens)
   // COUNT should be defined in the config if possible.
   $this->db->where/*... add more here...*/->limit( COUNT, $pos );
}

Realistically, you should look into your URI routing class or using the _resolve method, but this should do what you need it to.

I suggest to have a look at PEAR's awesome Pager package. It automatically generates a pager and gives you the correct indexes depending on the (GET) input variables.
