Question

我使用Paginator::make对表中的记录进行了分页。在视图中，我正在获取分页链接，但每个链接都包含其中的所有记录。如何将其限制为perPage个项目？

    $datas = Paginator::make($paginator, count($paginator), $perPage);
    return $datas;

代码输出：

{"total":10,"per_page":5,"current_page":1,"last_page":2,"from":1,"to":5,"data":

Answer 1

实际上Paginator :: make函数我们只需传递所需的值而不是所有值。因为paginator :: make函数只显示发送给它的数据。要将正确的偏移分页数据发送到paginator :: make，应遵循以下方法

    $paginator = json_decode($response);
    $perPage = 5;   
    $page = Input::get('page', 1);
    if ($page > count($paginator) or $page < 1) { $page = 1; }
    $offset = ($page * $perPage) - $perPage;
    $articles = array_slice($paginator,$offset,$perPage);
    $datas = Paginator::make($articles, count($paginator), $perPage);

希望这会对某人有所帮助......

Paginator::make()

此功能仅创建分页系统。要限制每个页面的数据，您必须对查询进行一些更改。这是一个例子。

        $pageNo = Input::get('page', 1);
        $perPage = 10;
        $from = $pageNo*$perPage-$perPage;
        $to = $perPage;

        $data['allData'] = DB::select( DB::raw('SELECT * FROM tablename LIMIT '.$from.','.$to));
        $totalData = DB::select( DB::raw('SELECT * FROM tablename'));
        $data['paginator'] = Paginator::make($data['allData'], count($totalData), $perPage);

然后您可以将数据显示到您的视图页面

您应加载view并使用以下内容将$datas传递给view：

return View::make('viewname')->with('datas', $datas);

然后在view循环$datas中的所有模型并打印出links，例如：

foreach($datas as $data) {
    echo $data['propertyname']; // $data['username'];
}

最后打印链接：

echo $data->links();

如果您使用Blade，请使用{{ $data['propertyname'] }}和{{ $data->links() }}代替echo，同时更改foreach，check here for more。另外，请确保您在viewname中使用了正确的make(...)，因为viewname方法中传递的make(...)默认情况下会从app/views文件夹中加载。

如何在laravel中使用pagination :: make（）来显示视图中的结果集？
