regarding api $page->prev and $page->next

[adrianmak]

These two api is convenience for developer for next adjacent page of current page.

But it only work for, in the order of pages creation

How could it possible for, let say

I generated a list of pages and sorted by a date field. That's the actual page order listed in the back-end is different from the front-end.

if I used $page->prev and $page->next, it reflect the order of the back-end but not the front-end (pages sorted by date)

Use this:

This should work:

$sortedPages = $pages->find('selector');
$prevPage = $page->prev($sortedPages);
$nextPage = $page->next($sortedPages);

As said in other replies, you can feed a pageArray. More info here:

This should work:

$sortedPages = $pages->find('selector');
$prevPage = $page->prev($sortedPages);
$nextPage = $page->next($sortedPages);

Many thanks~~~~
