Question

我的助手有一个功能

function somethingOrOther($id)
{
      $posts = Posts::where('author_id', $id);
      $posts_count = [];
      $posts_count['total'] = $posts->count();
      $posts_count['published'] = $posts->where('status', 'published')->count();
      $posts_count['draft'] = $posts->where('status', 'draft')->count();

      return $posts_count;
}

这个功能完美无缺。但是现在我正在尝试在控制器中使用它来将它返回到视图

public function profile($id)
    {
      $posts_count[]= somethingOrOther($id);

      return view ('display.profile')->withPosts_count($posts_count['total'])->withPosts_published_count($posts_count['published'])->withPosts_draft_count($posts_count['draft']);
}

但我收到'未定义索引：总计'的错误。我需要做什么来单独返回$ posts_count的数组值？

Answer 1

尝试

$post_count = $this->somethingOrOther($id);
if ( !$post_count ) {
     return "no posts for this author";
}
...
return view('display.profile', compact('post_count'));

在视图中

{{ $post_count['total'] }}

Answer 2

我相信你可以做到

$posts_count= somethingOrOther($id);

然后像

一样返回

return view ('display.profile',["posts_count" => $posts_count]);

并且在刀片中得到它

{{$posts_count["total"]}}

在Laravel 5.2中显示数组中的变量
