Trying to get property of non-object in view

can any one tell what i am doing wrong ? thank you

update

in my view for printing purpose i am using

{{print_r($single_view_user->toArray())}}

 <tr class="active">
             <th>Profile Picture</th>
                <td><img src="{{asset($single_view_user->avatar)}}" ></td>
            </tr>
            <tr class="active">
             <th>Username </th>
                <td>{{$single_view_user->username}}</td>
            </tr>

           <tr class="active">
             <th>email</th>
                <td>{{$single_view_user->email}}</td>
            </tr>
             <tr class="active">
             <th >Designation</th>
                <td>{{$single_view_user->designation}}</td>
            </tr>
             <tr class="active">
             <th>supervisor</th>
             <?php $single_view_user['supervisor']['username']; ?>
                <td>{{ $single_view_user['supervisor']->username}}</td>
            </tr>

and in my controller

$single_view_user = User::where('id',$id)->with('Supervisor')->first();

        return view('admin/single_view_user',['single_view_user'=>$single_view_user]);

Update 2

@foreach($single_view_user as $val)


{{print_r($val) }}

@endforeach

ouput will be like

11 11 11 1

答

Based on your with() method, it looks like your relationship method is Supervisor, not supervisor (uppercase vs lowercase). When you call toArray on the Model, it runs the relationship attributes through the Str::snake() method, which also lowercases them, which is why Supervisor appears as lowercase in your array output.

Try:

$single_view_user = User::where('id', $id)->with('Supervisor')->first();
dd($single_view_user->Supervisor->username);

As a side note, you could clean up your query a little bit as:

$single_view_user = User::with('Supervisor')->find($id);

答

It should be:

 $single_view_user['supervisor']['username'];

Because inside array is array not an object.

In your controller;

  $single_view_user = $single_view_user = User::where('id',$id)->with('Supervisor')->first();

  $convert = $single_view_user->toArray();
  return view('admin/single_view_user',compact('convert',$convert));

In your view:

<tr class="active">
         <th>Profile Picture</th>
            <td><img src="{{asset($convert['avatar'])}}" ></td>
        </tr>
        <tr class="active">
         <th>Username </th>
            <td>{{$convert['username']}}</td>
        </tr>

       <tr class="active">
         <th>email</th>
            <td>{{$convert['email']}}</td>
        </tr>
         <tr class="active">
         <th >Designation</th>
            <td>{{$convert['designation']}}</td>
        </tr>
         <tr class="active">
         <th>supervisor</th>
         {{$convert['supervisor']['username']}}
            <td>{{$convert['supervisor']['username']}}</td>
        </tr>

答

use the below code:
echo $yourarray['supervisor']['username'];

-> operator is used to access the property inside an object but what you have is an array. Array are accessed using the index.

Edited Part Answer: In your view use the below code:

<tr class="active">
             <th>Profile Picture</th>
                <td><img src="{{asset($single_view_user['avatar'])}}" ></td>
            </tr>
            <tr class="active">
             <th>Username </th>
                <td>{{$single_view_user['username']}}</td>
            </tr>

           <tr class="active">
             <th>email</th>
                <td>{{$single_view_user['email']}}</td>
            </tr>
             <tr class="active">
             <th >Designation</th>
                <td>{{$single_view_user['designation']}}</td>
            </tr>
             <tr class="active">
             <th>supervisor</th>
             <?php $single_view_user['supervisor']['username']; ?>
                <td>{{ $single_view_user['supervisor']['username']}}</td>
            </tr>
