Question

我正在使用devdojo的chatter讨论包来添加诸如stackoverflow之类的注释，因此这是我正在编写代码以显示注释的问题，但是出现未定义的变量错误。 Error Page ScreenShot

public function show(Chatterreply $chatterreply ,$id)
{
    $chatterreplies = Chatterreply::where('chatter_post_id',$id)->get();

    return view('chatter::discussion', compact('chatterreplies'));
    echo "<pre>"; print_r('$chatterreplies'); die;
}

在Web.php中，路由是

 /*
 * Post routes.
 */
Route::group([
    'as'     => 'posts.',
    'prefix' => $route('post', 'posts'),
], function () use ($middleware, $authMiddleware) {

    // All posts view.
    Route::get('/', [
        'as'         => 'index',
        'uses'       => 'ChatterPostController@index',
        'middleware' => $middleware('post.index'),
    ]);

    // Create post view.
    Route::get('create', [
        'as'         => 'create',
        'uses'       => 'ChatterPostController@create',
        'middleware' => $authMiddleware('post.create'),
    ]);

    // Store post action.
    Route::post('/', [
        'as'         => 'store',
        'uses'       => 'ChatterPostController@store',
        'middleware' => $authMiddleware('post.store'),
    ]);
    //Adding Comments
    Route::post('/reply/{id}', [
        'as'         => 'store',
        'uses'       => 'ChatterreplyController@store',
        'middleware' => $authMiddleware('post.reply.store'),
    ]);
    //showing Comment
    Route::get('/reply/{id}', [
        'as'         => 'show',
        'uses'       => 'ChatterreplyController@show',
        'middleware' => $middleware('post.show'),
    ]);

首先，我建议通过以下方式将调试语句（... print_r ...）放在控制器动作的return语句之前：

public function show(Chatterreply $chatterreply ,$id)
{
  $chatterreplies = Chatterreply::where('chatter_post_id',$id)->get();

  echo "<pre>"; print_r('$chatterreplies'); die();

  // or use the laravel helper 
  dd($chatterreplies)

  return view('chatter::discussion', compact('chatterreplies'));

}

您应该看到$ chatterreplies变量的内容。

如果可以，请在web.php中检查您的控制器名称，因为它似乎应该是ChatterReplyController @ show而不是Chatter reply Controller @ show（是Chatter中的R字母是否要回复 Controller @是否显示大写字母？）（例如，如果您遵循的是camelCase约定，例如在ChatterPostController @ store中。）

在Laravel Chatter软件包中显示数据显示未定义变量错误
