[英]How to limit amount of pages in laravel pagination?
I have a pagination and try to limit the amount of pages for that pagination.我有一个分页并尝试限制该分页的页数。 Every page has 50 results and the maximum amount of pages I want for this pagination is 200 (10k total entries from the table).
每页有 50 个结果,我希望这个分页的最大页数是 200(表中的总条目数为 10k)。 I tried the following:
我尝试了以下方法:
$page_count = 50;
$users = DB::Table('user_totalpoints')->where('points', '>', 0)
->orderBy('points', 'desc')
->orderBy('id', 'asc')
->take(10000)
->paginate($page_count);
The result of this is a pagination with 50 results per page but with ALL entries from the user_totalpoints table.这样做的结果是一个分页,每页有 50 个结果,但所有条目都来自 user_totalpoints 表。 take(10000) is ignored as there are only 50 taken by the pagination.
take(10000) 被忽略,因为分页只有 50 个。 So instead of maximum 200pages I now have thousands.
因此,我现在有数千页,而不是最多 200 页。

$collection = UserTotalPoint::where('points', '>', 0)
->orderby('points', 'desc')
->orderby('id', 'desc')
->take(10000)
->get();
$perPage = 50;
$currentPage = LengthAwarePaginator::resolveCurrentPage();
if ($currentPage == 1) {
$start = 0;
}
else {
$start = ($currentPage - 1) * $perPage;
}
$currentPageCollection = $collection->slice($start, $perPage)->all();
$paginatedTop = new LengthAwarePaginator($currentPageCollection, count($collection), $perPage);
$paginatedTop->setPath(LengthAwarePaginator::resolveCurrentPath());
return view('topPoints', ['top' => $paginatedTop ]);

]);
$page = $request->get('page');
$page_count = 50;

$paginator = new LengthAwarePaginator($users, $total, $page_count, $page);
dd($paginator->toArray()); // view result
