Laravel 5-手動ページ付け

Pagination::make()メソッドはLaravel 5のPaginationクラスに存在しなくなりました。

Laravel 5で手動ページ付けを機能させるための回避策はありますか?

用途を追加する必要があります:

use Illuminate\Pagination\LengthAwarePaginator as Paginator;

そして今、あなたは使うことができます:

 $paginator = new Paginator($items, $count, $limit, $page, [
            'path'  => $this->request->url(),
            'query' => $this->request->query(),
        ]);

モデルオブジェクトのページ付けと同じ形式でデータを取得します。

このように手動でページ付けを作成できます

$data = DB::table('post')->skip(0)->take(20)->get();

このクラスをインスタンス化するためのかなりの方法

_ use Illuminate\Pagination\LengthAwarePaginator as Paginator;
 //...
 $paginator = new Paginator($items->forPage($page, $limit), $count, $limit, $page, [
            'path'  => Paginator::resolveCurrentPath()
        ]);
_

itemsCollectionオブジェクトである必要があります。 collect(Array())を使用してArrayCollectionに変換します

Illuminate\Pagination\LengthAwarePaginatorの使用例:

use Illuminate\Http\Request;
use Illuminate\Pagination\LengthAwarePaginator;

public function getItems(Request $request)
{
    $items = []; // get array/collection data from somewhere
    $paginator = $this->getPaginator($request, $items);

    // now we can treat $paginator as an array/collection
    return view('some-view')->with('items', $paginator);
}

private function getPaginator(Request $request, $items)
{
    $total = count($items); // total count of the set, this is necessary so the paginator will know the total pages to display
    $page = $request->page ? $request->page : 1; // get current page from the request, first page is null
    $perPage = 3; // how many items you want to display per page?
    $offset = ($page - 1) * $perPage; // get the offset, how many items need to be "skipped" on this page

    $items = array_slice($items, $offset, $perPage); // the array that we actually pass to the paginator is sliced

    return new LengthAwarePaginator($items, $total, $perPage, $page, [
        'path' => $request->url(),
        'query' => $request->query()
    ]);
}

次に、some-view.blade.phpファイルで次のようになります。

@foreach($items as $item)
    {{--  --}}
@endforeach


{{ $items->links() }}

public function myData($userid)
{
    $data = static::get();


    $result = [];
    if(!empty($data)){
        foreach ($data as $key => $value) {
            $result[$value->type.'-'.$value->postid][] = $value;
        }
    }


    $paginate = 10;
    $page = Input::get('page', 1);


    $offSet = ($page * $paginate) - $paginate;  
    $itemsForCurrentPage = array_slice($result, $offSet, $paginate, true);  
    $result = new \Illuminate\Pagination\LengthAwarePaginator($itemsForCurrentPage, count($result), $paginate, $page);
    $result = $result->toArray();
    return $result;

手動ページ付けについては、以下のコードを試してください

<?php

namespace App\Http\Controllers;

use Illuminate\Pagination\LengthAwarePaginator as Paginator;
// use Illuminate\Pagination\Paginator;
use Illuminate\Http\Request;
use App\Product;
class MyController extends Controller
{
    public function index(Request $request){
        $items = Product::all();

        $filter_products = []; // Manual filter or your array for pagination

        foreach($items as $item){
            if($item['id']>40 && $item['id']<50){
                array_Push($filter_products, $item);
            }
        }

        $count = count($filter_products); // total product for pagination
        $page = $request->page; // current page for pagination

        // manually slice array of product to display on page
        $perPage = 5;
        $offset = ($page-1) * $perPage;
        $products = array_slice($filter_products, $offset, $perPage);

        // your pagination 
        $products = new Paginator($products, $count, $perPage, $page, ['path'  => $request->url(),'query' => $request->query(),]);
        // use {{ $products->appends($_GET)->links() }} to dispaly your pagination
        return view('index',['products' => $products]);
    }
}
