Question

以下是显示数据的显示页面代码：

@extends('layouts.app')

@section('content')


<div class="container">
    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            <div class="panel panel-default">
                <div 
                    class="panel-heading">subnet_behind_clients
                </div>

                <div class="panel-body">
                    <form class="form-horizontal" role="form" method="GET" action="{{ url('/subnet_behind_clients') }}">
                        {{ csrf_field() }}
                            <table class="table table-hover">
                                <thead>
                                    <tr>
                                        <th></th>
                                        <th>client_id</th>
                                        <th>ip_address</th>
                                        <th>netmask</th>
                                    </tr>
                                </thead>
                                <tbody>
                                @foreach($clients as $client)
                                    <tr>
                                        <td>{{ ++$i }}</td>
                                        <td>{{ $client->ip_address }}</td>
                                        <td>{{ $client->netmask }}</td>
                                        <td>
                                            <button type = "button" class = "btn btn-danger " data-target = "del/{{$client->id}}">Delete</button> 
                                        </td>
                                    /tr>
                                @endforeach
                            </tbody>
                        </table>
                    <div class="panel-body">
                        <a href="{{ url('/home') }}">Home</a>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
@endsection

以下是我的控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;

use App\Subnet_behind_client;
use DateTime;

class Subnet_Behind_ClientController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index(Request $request)
    {

                /* $datas = Subnet_behind_client::all();
                $data = $datas->first();*/

                $data = Subnet_behind_client::first();

                return view('subnet_behind_clients',compact('data'));
    }


    public function create(Request $request)
    {

                $data = new Subnet_behind_client;
                return view('subnet_behind_clients1',compact('data'));
                Subnet_behind_client::create([
                    //'client_id' => $request->input('1'),
                    'ip_address' => $request->input('ip_address'),
                    'netmask' => $request->input('netmask'),
                ]);
    }



    public function store(Request $request)
    {
                $datas = Subnet_behind_client::all();
                $data = new Subnet_behind_client;
                $data->client_id = '1';
                $data->ip_address = $request->ip_address;
                $data->netmask = $request->netmask;

                $data->save();
                return back();

    }

    public function show(Request $request)
    {
                $clients = Subnet_behind_client::all();
                return view('view2',compact('clients'));
    }
            public function destroy($id)
            {
                $clients = Subnet_behind_client::findOrFail( $id );
                $clients->delete();
                return view('view2',compact('clients'));
            }  
    }

请告诉我foreach中的代码有什么问题第一部分是视图页面第二页是控制器部分我编辑了我之前的帖子。 Plz看一看，让我知道。

Answer 1

试试这个

控制器

use App\Subnet_behind_clients

public function show(Request $request)
{
     $datas = Subnet_behind_clients::all();
     return view('view2',compact('datas'));
}

视图

@foreach($datas as $data)
<tr>

    <td>{{ ++$i }}</td>

    <td>{{ $data->ip_address }}</td>

    <td>{{ $data->netmask }}</td>
</tr>

@endforeach

Answer 2

如果你有Class 'App\Http\Controllers\Subnet_behind_clients' not found

在控制器

中的命名空间后使用use App\Subnet_behind_clients（模型名称空间）

您忘记在控制器中添加模型的名称空间

Answer 3

您的控制器应如下所示：

use App\Subnet_behind_clients;

public function show(Request $request)
{
    $clients = Subnet_behind_clients::all();
    return view('view2', compact('clients '));
}

并查看：

@foreach($clients as $client)
    ....
@endforeach

切勿在视图中使用Eloquent或Query Builder。

我正在尝试检索数据并将其显示在laravel 5.3中的页面中
