Laravel 5和长度感知分页 [英] Laravel 5 and Length Aware Pagination

问题描述

我还有另一个分页问题.当我遍历下面的分页数组时，每页都会得到整个数组.

I've got another pagination problem it looks like. When I iterate over the paginated array below, I get the entire array every page.

$array = [...];
$ret = new LengthAwarePaginator($array, count($array), 10);
// dd($ret);

LengthAwarePaginator {#302 ▼
  #total: 97
  #lastPage: 10
  #items: Collection {#201 ▼
    #items: array:97 [▶]
  }
  #perPage: 10
  #currentPage: 1
  #path: "/"
  #query: []
  #fragment: null
  #pageName: "page"
}

从雄辩的模型构建LAP时不是这种情况，例如:Blah::paginate()

This isn't the case when building a LAP from an eloquent model eg: Blah::paginate()

推荐答案

分页器不会自动为您分割给定的数组.您必须先将其切片，然后再将其传递给分页器.

The paginator does not slice the given array for you automatically. You have to slice it yourself before you pass it to the paginator.

要使您的生活更轻松，请使用collect助手来创建laravel集合的实例，这使得分割非常容易:

To make life easier for you, use the collect helper to create an instance of a laravel collection, which makes it very easy to slice up:

$items = collect([...]);
$page = Input::get('page', 1);
$perPage = 10;

$paginator = new LengthAwarePaginator(
    $items->forPage($page, $perPage), $items->count(), $perPage, $page
);
