Laravel未定义变量：名称

Question

你好，我试图将$ Name传递给视图，我似乎无法让它工作，我按照线路行的视频似乎无法工作任何帮助将非常感激。

编辑。我知道这是新手级别，但它现在给我的项目带来了最多麻烦。

控制器

    <?php

namespace App\Http\Controllers;

use Illuminate\Foundation\Bus\DispatchesJobs;
use Illuminate\Routing\Controller as BaseController;
use Illuminate\Foundation\Validation\ValidatesRequests;
use Illuminate\Foundation\Auth\Access\AuthorizesRequests;

abstract class RequestController extends BaseController
{
    public function GetName(){
        $name = ['one','two','three'];
        return view::make('home', ['name' => $name]);
    }
} 

routes.php文件

<?php

/*
|--------------------------------------------------------------------------
| Application Routes
|--------------------------------------------------------------------------
|
| Here is where you can register all of the routes for an application.
| It's a breeze. Simply tell Laravel the URIs it should respond to
| and give it the controller to call when that URI is requested.
|
*/

Route::get('/', function () {
    return view('welcome');
});

Route::get('home', 'RequestController@GetName');

查看

@foreach( $name as $names)
<tr>
<th>{{ $names }}</th>
</tr>
@endForeach

Answer 1

在您的控制器

中

return view('home')->with('name', $name);

并且在您看来，做了已经存在的foreach，它应该按预期工作。

提示：

要调试此功能，您只需执行isset print_r等，

另外，请确保您从路径中调用控制器中的正确功能

Answer 2

你可以尝试：

        return View::make( 'home' ,compact('name')); 

或

        return View::make('home', ['name' => $name]);

也在顶部添加：

        use \View as View;
