Question

我有两个问题：

$posts = Post::all();

$comments = Comment:all();

我后来合并：

$merge = $posts->merge($comments);

$all = $merge->sortByDesc(function($result) {
    return $result->created_at;
});

如何对合并结果进行分页？执行$all->paginate(25)不起作用。

Answer 1

Laravel 5：

在Laravel 5中，可以通过实例化paginator轻松完成：

$paginator = new Illuminate\Pagination\Paginator($all, $perPage, $currentPage);

Answer 2

您可以尝试此操作（Version-5x）：

// Add this at the top of your class
 use Illuminate\Pagination\LengthAwarePaginator as Paginator;

 // Then use following code:
 $perPage = 10;
 $currentPage = app('request')->get('page') ?: 1; // or $request->get('page') if available
 $paginator = new Paginator($all, $all->count(), $perPage, $currentPage);

对于4.2，请尝试以下语法：

$items = $all->toArray();
$total = count($items);
$perPage = 10;
$paginator = Paginator::make($items, $total, $perPage);

Answer 3

Laravel 5：

您可以使用spatie/laravel-collection-macros。

$posts = Post::all();

$comments = Comment:all();

return $comments->merge($posts)->paginate();

Paginate合并查询
