过滤后的Laravel 5.3链分页 [英] Laravel 5.3 chain paginate after filter

问题描述

$posts = Post::all()->filter(function($item) use (&$pYear){
    return Persian::jDate(...) == $pYear;
})->sortByDesc('id')->paginate(5);

当我链接paginate(5)时，出现此错误方法paginate不存在."，我该如何对我的结果进行分页，请帮忙，谢谢.

When I chain paginate(5), I get this error "Method paginate does not exist.", How can I paginate my result, please help, thank you.

推荐答案

最后，我通过创建我的收藏夹的自定义分页器解决了它，也许这不是最好的方法，无论如何我的代码都找不到更短的解决方案现在可以正常工作.

Finally I solved it by creating a custom paginator of my collection, Maybe this is not the best way, I couldn't find a shorter solution, anyway my code works fine now.

use Illuminate\Pagination\LengthAwarePaginator;

protected $perPage = 5;

$posts = Post::get()->filter(function($item) use (&$pYear){
    return Persian::jDate(...) == $pYear;
})->sortByDesc('id');

//this code simulates: ->paginate(5)
$posts = new LengthAwarePaginator(
         $posts->slice((LengthAwarePaginator::resolveCurrentPage() *
         $this->perPage)-$this->perPage,
         $this->perPage)->all(), count($posts),
         $this->perPage, null, ['path' => '']);
