Question

我正在尝试返回位于视图子文件夹中的视图：

我有一个调用控制器的路由，在index函数中它返回视图：

路线：

Route::resource('employee','EmployeeController');

控制器：

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Employee;



class EmployeeController extends Controller
{
/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    //
    return view('employee.index');
}

/**
 * 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)
{
    //
}

/**
 * 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)
{
    //
}
}

当我尝试以下网址时：

http://cats/employee

我收到此错误消息：

哎呀，好像出了什么问题。 2/2 ErrorException in 10f0bf4300a070310e2f44dc1b237ad9e8092472.php第14行：使用未定义的常量员工 - 假定为'employee'（查看：C：\ inetpub \ vhosts \ cats \ resources \ views \ employee \ index.blade.php）

此代码是否存在问题：

return view('employee.index');

我是否在不知不觉中犯了错误？

编辑：这是正在加载的视图：

    !DOCTYPE html>
<html lang="{{ config('app.locale') }}">
    <head>
        <meta charset="utf-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <title>Laravel CRUD Operations</title>

    </head>
    <body>
        <div>
            <span>All employees</span>
            <a style="float:right;" href="{{  route(employee.create) }}">Create     New Employee</a>
        </div>
        <br>
        <br>
        <br>
        @if ( message == Session::get('success'))
        <p><i> {{ message }},</i></p>
        @endif

        <br>
        <br>
    </body>
    </html>

Answer 1

错误消息所述的问题是您在employee模板中使用employee.index变量而未将其作为参数传递给视图。

在您的控制器而不是return view('employee.index');中，您可以先检索员工详细信息，然后执行以下操作：

返回视图（＆＃39; employee.index＆＃39;，[＆＃34;员工＆＃34; =＆gt; $员工]）;

假设$employee变量已填入员工详细信息

Laravel 5返回视图不起作用
