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:

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:

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() }}
