Laravel 5.3过滤后的链分页

Question

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

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

Answer 1

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' => '']);
 

Answer 2

Try removing all()

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