Question

在Laravel 5中，

Pagination::make()方法在Pagination类中不再存在。

是否有解决方法在Laravel 5中进行手动分页？

Answer 1

您需要添加用途：

use Illuminate\Pagination\LengthAwarePaginator as Paginator;

现在你可以使用：

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

以与模型对象上的分页相同的格式获取数据;

Answer 2

您可以像这样创建手动分页

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

Answer 3

实例化这个类的好方法

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

注意 items必须是Collection对象。

Answer 4

尝试下面的手动分页代码

<?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]);
    }
}

使用Illuminate\Pagination\LengthAwarePaginator的示例：

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()
    ]);
}

然后在some-view.blade.php文件中，例如：

@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;
}

Answer 7

基于@Avishay28，我认为不需要php array_slice。

在 laravel 8 中工作。

我认为就性能而言，这是一种更好的方法，因为我们没有查询“SELECT * FROM products”

$items_per_page = 5;
$page_id = (int)$request->query('page') ?? 1;
$model_docs_count = Product::count();
$total_pages = ceil($model_docs_count / $items_per_page);
$model = Product::skip(($page_id - 1) * $items_per_page)->limit($items_per_page)->latest();
// dd($model->toSql()); "SELECT * FROM `products` WHERE ORDER BY `created_at` DESC LIMIT 5 OFFSET 0"

$custom_paginate = new LengthAwarePaginator($model, $total_pages, $items_per_page, $page_id, [
    'path' => $request->url(),
    'query' => $request->query()
]);

return response()->json([$custom_paginate], 200);

Answer 8

使用分页的另一种方式是这样的：

public function index()
{
    $posts = DB::table('posts')->paginate(15);
}
