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

Question

我曾经用于Paginator::make对表中的记录进行分页.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":      
[{"id":"10","languages":"ds","created_at":"2014-05-23

实际上 Paginator::make 函数我们只需要传递所需的值而不是所有值。因为 paginator::make 函数只是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);

希望这会帮助某人...

您应该加载 aview并将其传递$datas给view使用如下所示的内容：

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

然后在view循环中输入所有模型$datas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();

如果您正在使用Bladethen 使用{{ $data['propertyname'] }}和{{ $data->links() }}来代替echoand 并进行更改foreach，请在此处查看更多信息。还要确保您使用了正确的viewnamein make(...)，因为默认情况下viewname传入的make(...)方法将从文件夹加载app/views。
