ErrorException在ClientController.php線120：嘗試分配非對象的屬性Laravel 5.2

我填寫表格編輯客戶端，則必須使用介入圖像附加的圖像，它是產生以下錯誤：ErrorException在ClientController.php線120：嘗試分配非對象的屬性Laravel 5.2

ErrorException in ClientController.php line 120: Attempt to assign property of non-object.

這是我的模型：

<?php 

namespace App; 

use Illuminate\Database\Eloquent\Model; 

class Client extends Model 
{ 
    protected $table = 'clients'; 

    protected $fillable = ['status_id', 'name', 'identity', 'address', 'location', 'l_number', 'province_id', 'email', 'email2', 'phone', 'movil', 'requirement_id', 'budget', 'user_id', 'comments']; 

    // Relation with Status client 
    public function statusclient() 
    { 
     return $this->belongsTo('App\Statusclient', 'status_id'); 
    } 

    // Relation with Province 
    public function province() 
    { 
     return $this->belongsTo('App\Province'); 
    } 

    // Relation with Province 
    public function requirement() 
    { 
     return $this->belongsTo('App\Requirement'); 
    } 

    // Relation with User 
    public function user() 
    { 
     return $this->belongsTo('App\User'); 
    } 
}

這是我的更新方法：

public function update(Request $request, $id) 
    { 
     $updated = Client::findorFail($id); 

     $this->validate($request, [ 
      'name' => 'required' 
     ]); 

     $clients = $request->all(); 

     $updated->fill($clients)->save(); 

     if($request->hasFile('avatar')){ 
      $avatar = $request->file('avatar'); 
      $filename = time() . '.' . $avatar->getClientOriginalExtension(); 
      Image::make($avatar)->resize(300, 200)->save(public_path('uploads/clients/' . $filename)); 

      $clients->avatar = $filename; 
      $clients->save(); 
     } 

     return redirect()->route('clients.index') 
         ->with('success','Cliente actualizado satisfactoriamente!!!'); 
    }

這是形式：

標出錯誤行可能會有所幫助。 –

對不起，我沒有看到它是如何組織的。 –

'$ clients'不是一個對象，我認爲它是一個數組。我將它改爲'$ updated-> avatar' – Beginner

所以這裏的問題是雙重的：

首先，你正試圖設置屬性avatar，這在request陣列中不存在。
其次，你試圖更新$clients這實際上是一個數組 - 這意味着你不能save()什麼，因爲它不是一個模型。

從剛纔看你的代碼，它會出現，你會想做的事：

$updated->avatar = $filename; 
$updated->save();

相反的：

$clients->avatar = $filename; 
$clients->save();

希望這有助於！

只需要注意，'$ request-> all（）'返回一個數組，所以'$ clients'實際上是一個數組，而不是'Request'對象。這就是導致報告的初始錯誤（試圖爲數組（非對象）分配'avatar'屬性）。 – patricus

非常感謝，解決了我的錯誤並考慮到了它的建議。 –

@patricus相應修正 – Derek
