laravel手动数组分页

laravel文档中已经有写如何自己使用分页类去分页了，但没有详细说明。

如果你想手动创建分页实例并且最终得到一个数组类型的结果，可以根据需求来创建 IlluminatePaginationPaginator 或者 IlluminatePaginationLengthAwarePaginator 实例来实现。

具体可以看IlluminatePaginationLengthAwarePaginator中的这段代码：

复制代码

public function __construct($items, $total, $perPage, $currentPage = null, array $options = [])
 {
  foreach ($options as $key => $value) {
   $this->{$key} = $value;
  }
 
  $this->total = $total;
  $this->perPage = $perPage;
  $this->lastPage = max((int) ceil($total / $perPage), 1);
  $this->path = $this->path !== '/' ? rtrim($this->path, '/') : $this->path;
  $this->currentPage = $this->setCurrentPage($currentPage, $this->pageName);
  $this->items = $items instanceof Collection ? $items : Collection::make($items);
 }

以下为具体实现代码：

复制代码

use Illuminate\Pagination\LengthAwarePaginator;

 

复制代码

public function index(Request $request)
 {
  //数据A
  $dataA = User::where('status', 1)->get()->toArray();
  //数据B
  $dataB = User::where('status', 2)->get()->toArray();
  $data = array_merge($dataA, $dataB);
  //当前页数 默认1
  $page = $request->page ?: 1;
  //每页的条数
  $perPage = 4;
  //计算每页分页的初始位置
  $offset = ($page * $perPage) - $perPage;
   //实例化LengthAwarePaginator类，并传入对应的参数
  $data = new LengthAwarePaginator(array_slice($data, $offset, $perPage, true), count($data), $perPage,
   $page, ['path' => $request->url(), 'query' => $request->query()]);
  return view('admin.users.index', compact('data'));
 }
 
//视图中
{{ $data->links() }}
