Question

我的视图（drivers.blade.php）无法从DriverController索引方法识别变量？我的模型名称是Driver。

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Driver;

class DriverController extends Controller
{
/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    $driver = Driver::all();
    return view('drivers', compact('drivers'));
}

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function create()
{
    //

}

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{

    Driver::create($request->all());
    return back();
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    //
}

/**
 * Show the form for editing the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function edit($id)
{
    //
}

/**
 * Update the specified resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function update(Request $request, $id)
{
    //
}

/**
 * Remove the specified resource from storage.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function destroy($id)
{
    //
}
 }

这应该从数据库中获取所有数据，然后显示它们，我正在尝试创建一个CRUD，但我总是收到此错误“未定义变量：驱动程序（视图：C：\ xampp \ htdocs \ laravel \ resources \ views \ drivers.blade.php）”。

  <h2>All Drivers</h2>

   <table id="example2" class="table table-responsive" role="grid" aria-describedby="example2_info">
<thead>
<tr>
     <th>Fname</th>
     <th>Mname</th>
     <th>Lname</th>
     <th>Phone</th>
     <th>Address</th>
     <th>Hired</th>
     <th>License_no:</th>
</tr>

     @foreach($driver as $drive) 
     <tbody>
     <tr>
           <td>{{$drive->fname}}</td>
           <td>{{$drive->mname}}</td>
            <td>{{$drive->lname}}</td>

            <td>{{$drive->address}}</td>
            <td>{{$drive->hire_date}}</td>
            <td>{{$drive->license_no}}</td>

     </tr>

 </tbody>

 @endforeach

</table>

Answer 1

在索引函数中，变量名称为$ driver，并且您正在传递驱动程序。将其更改为以下内容：

public function index()
{
    $driver = Driver::all();
    return view('drivers', compact('driver'));
}
