Laravel 5.1 指定当前页进行分页

Question

为此努力了太久，没有结果。我试过了。

`\Illuminate\Pagination\Paginator::setCurrentPage($current_page);`

returns Call to protected method Illuminate\Pagination\Paginator::setCurrentPage()

\Paginator::setCurrentPage($current_page);

returns Call to protected method Illuminate\Pagination\Paginator::setCurrentPage()

\DB::getPaginator()->setCurrentPage($current_page);

returns call_user_func_array() expects parameter 1 to be a valid callback, class 'Illuminate\Database\MySqlConnection' does not have a method 'getPaginator'

$tmp = new Post( ); $tmp->getConnection()->setCurrentPage($current_page);

returns call_user_func_array() expects parameter 1 to be a valid callback, class 'Illuminate\Database\MySqlConnection' does not have a method 'getPaginator'

如何指定页面？我需要手动指定。

我曾希望它像 $model->find( )->paginate($per_page, $page)

一样简单

Answer 1

假设您有 $users 在 UserController 中分页，您可能会这样做：

public function index()
{
    $currentPage = 3; // You can set this to any page you want to paginate to

    // Make sure that you call the static method currentPageResolver()
    // before querying users
    Paginator::currentPageResolver(function () use ($currentPage) {
        return $currentPage;
    });

    $users = \App\User::paginate(5);

    return view('user.index', compact('users'));
}

我相信这适用于 Laravel 5.0 及以上。必须检查一下。

Answer 2

Builder Class 有：

public function paginate($perPage = null, $columns = ['*'], $pageName = 'page', $page = null)

您可以拨打

Model::find(...)->paginate($per_page, ['*'], 'page', $page);

Answer 3

对于那些使用 api 并且他们想要在 api 中指定当前页面的人，他们可以使用像这样的额外参数：

getProducts?page=3
