How to use paginate() with a having() clause when column does not exist in table

Question

I have a tricky case ...

Following database query does not work:

DB::table(\'posts\')
->select(\'posts.*\', DB::raw($haversineSQL . \' as distance         


        

Answer 1

You can use manual pagination as having behaving peculiar with pagination class.

$posts = DB::table('posts')
    ->select('posts.*', DB::raw($haversineSQL . ' as distance'))
    ->having('distance', '<=', $distance)
    ->get();

// Items per page
$perPage = 10;
$totalItems = count($posts);
$totalPages = ceil($totalItems / $perPage);

$page = Input::get('page', 1);

if ($page > $totalPages or $page < 1) {
    $page = 1;
}

$offset = ($page * $perPage) - $perPage;

$posts = array_slice($posts, $offset, $perPage);

$posts = Paginator::make($posts, $totalItems, $perPage);


dd($posts);
