Question

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

当我链接paginate（5）时，我收到此错误“方法paginate不存在。”，我如何分页我的结果，请帮助，谢谢。

Answer 1

最后我通过创建我的集合的自定义分页器来解决它，也许这不是最好的方法，我找不到更短的解决方案，无论如何我的代码现在工作正常。

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' => '']);

Answer 2

尝试删除all()

$posts = Post::filter(function($item) use (&$pYear){
    return Persian::jDate('Y', strtotime($item->created_at),'','Asia/Tehran','en') == $pYear;
})->sortByDesc('id')->paginate(5);

过滤后的Laravel 5.3链分页
