試圖在更新 function 時獲取非對象的屬性“id”

Question

我有一個簡單的博客，現在我可以在我的博客中添加、刪除元素我希望用戶能夠更新標簽。

這是我的 phpmyadmin 中的頁面列表標簽表

page_lit_tags table

    id  name

    1   test1
    2   test2

這是標簽表

這是標簽 controller

use Illuminate\Http\Request;
use App\Tag;
use App\PageList;

class TagController extends Controller
{

    public function index()
    {
        $tags = Tag::all();
        $pages = PageList::all();
        return view('pages.index', compact('tags', 'pages'));
    }

    public function store(Request $request)
    {
        $this->validate($reguest, array('name'=>'required|max:255'));
        $tag = new Tag;
        $tag->name = $request->name;
        $tag->save();
        $request->session()->flash('succes', 'Tag was successful created!');
        return redirect()->route('pages.index');
    }
}

這是我的頁面列表 controller 更新 function

  public function update(Request $request, $id)
    {
        $pages = PageList::find($id);
        $pages->pagetitle =  $request->get('pagetitle');
        $pages->articlelist = $request->get('articlelist');
        $pages->status = $request->get('status');

        $pages->save();

        $pages->tags()->saveMany([
            new Tag(),
            new Tag(),
        ]);

        return redirect('/pages')->with('success', 'pages updated!');
    }

這是我的頁面 inde.blade.php 我在其中顯示我的數據

<tbody>
    @foreach ($pages as $page)

    <tr>
        <td>
            {{$page->id}}
        </td>
        <td>
            {{$page->pagetitle}}
        </td>
        <td>
            {{$page->articlelist}}
        </td>
        <td>

            <button type="button" class="btn btn-sm btn-success" data-toggle="modal" data-target="#exampleModal{{$page->id}}">
                {{ __('view tags') }}
            </button>
            <!-- Modal -->

            <div class="modal fade" id="exampleModal{{$page->id}}" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

                                    <th>
                                        name
                                    </th>
                                </thead>
                                <tbody>
                                    @foreach ($page->tags as $tag)

                                        <td>
                                            {{ $tag->tag->id }}

                                    </tr>
                                    @endforeach

                                </tbody>

注意：我對 laravel 伙計們太陌生了。

當我運行我的應用程序時，出現以下問題

Trying to get property 'id' of non-object (View: C:\custom-xammp\htdocs\royalad-dashboard\resources\views\pages\index.blade.php)

這是我的 repo存儲庫

我在我的代碼中做錯了什么？

Answer 1

如果$page->tags給你一個標簽的集合，你應該簡單地做$tag->id而不是$tag->tag->id （對於 name 屬性也是如此）
