Question

我正在尝试在laravel项目中更新图像，但不会保存图像，我正在使用intervention package

这是我使用dd的结果

控制器：

 public function update(Request $request, $id)
{
    //
    $this->validate($request, [
        'student_name'=>'required|max:50',
        'lead_status'=>'required|max:50',
        'lead_source'=>'required|max:50',
        'avatar' =>'image',



        ]);


        $leads = Lead::findOrFail($id);
        $leads->student_name = $request->student_name;
        $leads->student_nric = $request->student_nric;
        $leads->gender = $request->gender;
        $leads->religion = $request->religion;
        $leads->race = $request->race;
        $leads->date_of_birth = $request->date_of_birth;
        $leads->Address = $request->Address;
        $leads->last_school_attended= $request->last_school_attended;
        $leads->last_grade_completed = $request->last_grade_completed;
        $leads->grade_appliying = $request->grade_appliying;



        if($request->hasFile('avatar')){

            $image=$request->file('avatar');
            $filename=time() . '.' . $image->getClientOriginalExtension();
            $location=public_path('images/' .$filename);
            Image::make($image)->resize(300, 300)->save($location);

            $leads->image=$filename;


            $leads->save();
       }
       else{


        $leads->save();

        session()->flash('notif','Application Saved     Successfully');
      return view('leads.edit')->with('leads', $leads);
    }

}

编辑刀片视图

    <div class="row">
<div class="col-sm-4 form-group">
<img src="/uploads/avatars/{{$leads->image}}" style="width:150px;height:150px;border-radius:50px;">

<form enctype="multipart/form-data" action="{{route('leads.update', $leads->id)}}" method="POST" >
{{ csrf_field() }}
{{ method_field('PUT') }}
<label> Upload Image</label>
<input type="file" name="avatar">
<input type="hidden"  name="_token" value="{{ csrf_token() }}">

</div>


<div class="col-sm-12">
   <h4 text-muted>CHILD'S INFORMATION</h3>
   <hr>

                  <div class="row">
                        <div class="col-sm-4 form-group">

                            <label>FULLNAME</label>

                            <input class="form-control" style="text-transform: uppercase;" type="text" name="student_name" value="{{$leads->student_name}}" placeholder="Enter FULLNAME.."  autocomplete="off">

                        </div>

注意：如果图像显示为空，我将始终以null值结束。

在编辑刀片中添加具有数据库变量的隐藏输入类型并将您隐藏的输入名称的值置于else条件下进行保存。

<input type="hidden" name="old_image_name" 
value="@if(isset($admin_details)){{$admin_details->image}} @endif"/>

laravel中的更新图像无法正常工作
