Question

这是我的代码。如何正确定义$ bgprofile？我想知道如果我不放置isset，为什么会出现$ bgprofile undefine错误。 Evenso，除了看之外，我没有看到出现的图片集。任何线索？下面我发布了我的SettingController.php，Setting.blade.php和Routes.php。

SettingController.php

public function getBackgroundProfile(Request $request)
{
    $domain = $_SERVER['SERVER_NAME'];
    $user = User::where('domain', $domain)->first();

    $bgprofiles = DB::table('user_bgprofile')->where('user_id', $user->id)->get();    

    return view('soulfy.setting', [
            'bgprofiles' => $bgprofiles,
            'user' => $user,
        ]);
}

Setting.blade.php

     <form action="{{URL::to('/home/theme')}}" method="post"> 
                                    <span class="setting-name">THEME</span>

                                    <!-- <form method="POST" action="/posts"> -->
                                    {{ csrf_field() }}  
                                    <span class="setting-value center">

                                    <select name="menu">

routes.php文件

   Route::get('home/bgprofile', 'SettingController@getBackgroundProfile');

您在$bgprofile文件中定义settings.blade.php的位置？您传递给视图的变量是$bgprofiles（复数），因此如果在任何地方都没有定义 - 除非您正在添加，否则您将被引发错误isset条件，在这种情况下，它会看到它没有被定义，也没有继续进行。

如果我不放置isset，为什么$ bgprofiles是unfine？
