如何在laravel中搜索产品页面添加分页

Question

我想使用我的show controller为我的搜索产品项目视图添加分页

这是我的控制器

public function show($id)
    {
        $categories = Item::all();

        $products = Item::find($id)->products->paginate(3);

        return view('category.index', compact('categories', 'products'));
    }

这是我的观点

@extends('layout.front')


@section('page')

<div class="row" id="portfolio">


    <!-- Page Content -->
    <div class="container">

        <div class="row">

            <div class="col-lg-3" style="margin-top:20px;">

                <nav class="main-nav">
                    <ul class="main-nav-ul">
                        <li style="background-color: #343A40; color: #ffffff; font-weight: 600;" id="sidebar-header"><a>Product List</a></li>
                        <li><a href="{{ url('/computer') }}" style="font-weight: 600;">Computer<span></span></a>
                            <ul>
                                @if(!empty($categories))
                                    @forelse($categories as $category)
                                        <li><a href="{{ route('category.show', $category->id)}}">{{ $category->name }}</a></li>

                                    @empty
                                        <li>No data found</li>
                                    @endforelse
                                @endif
                            </ul>
                        </li>
                        <li><a href="#" style="font-weight: 600;">CCTV</a></li>
                        <li><a href="#" style="font-weight: 600;">Gaming</a></li>
                    </ul>
                </nav>

            </div>
            <!-- /.col-lg-3 -->

            <div class="col-lg-9">


                <div class="row" style="margin-top:20px;">


                    @if(!empty($products))
                        @foreach($products as $key=>$product)

<div class="col-lg-12">{!! $products->links() !!}</div>

我使用laravel默认分页并自定义我的bootstrap分页到laravel。

但在我的show函数中，控制器分页不起作用。如何修复搜索产品的分页。

我用链接方法。但它并不适用于这种观点。

<div class="col-lg-12">{!! $comproducts->links() !!}</div>

Answer 1

您没有在代码中的任何位置使用分页。请查看有关如何添加分页的文档。在进行db调用时需要使用paginate函数，然后使用paginator链接。

https://laravel.com/docs/5.5/pagination

Answer 2

{{$products->render()}}

把它放在foreach循环的末尾。

Answer 3

嗨请在这里找到分页代码

表：股票PK：id，Varchar：名称

股票Controller.php

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\DB;

class StockController extends Controller {

public function usaPage() {
    $stocks = DB::table('stocks')->orderBy('name', 'ASC')->paginate(50);

    return view('stock.usa', ['stocks' => $stocks]);
}
