如何在Laravel的编辑视图中更新图像? [英] How can I update image in edit view in laravel?

问题描述

在laravel中，我在编辑视图中有一个名为Profile Picture的字段，每当我单击编辑"按钮时，我都会从数据库中获得所有值，但没有图像；如果每次我单击提交"按钮，我必须上传图像，否则我将无法进一步处理.如果我不上传新图像，则表单将自动考虑旧的个人资料图片

In laravel I have a field in my edit view named Profile Picture, whenever I click On edit button I got all the values from database in edit view but I don't get image, And If whenever I click on submit button everytime I have to upload image without that I can't process further I want If I not upload new image then form will automatic consider old profile pic

我的刀片文件就像

<div class="col-md-6">
    <div class="form-group">
        <label for="photo">Profile Picture :<span class="danger">*</span> </label>
        <div class="row">
            <div class="col-md-9">
                    <input type="file" class="form-control" id="file" name="file">
            </div>
            <div class="col-md-3">
                @foreach ($empProfilePic as $empProfilePicture)
                    @if($employee->id == $empProfilePicture->id)
                        <img src="uploads/images/{{ $empProfilePicture->file }}" id="profile-img-tag" height="100" width="100">
                    @endif
                @endforeach
            </div>
        </div>
    </div>
</div>

控制器文件

 public function updateEmployee(Request $request, $id)
    {
        $employee = User::find($id);
        //Get inputs for personal detail

推荐答案

在控制器中:

更新文件的代码:

仅当您选择要更新的文件时，它才会更新.

Its update only when you select a file for the update.

在这里，我使用可以用您的模型替换的Employee模型

Here I use the Employee model you can replace with your model

public function update(Request $request, $id){

     $employee = Employee::find($id);

     if($request->file != ''){        
          $path = public_path().'/uploads/images/';

          //code for remove old file
          if($employee->file != ''  && $employee->file != null){
               $file_old = $path.$employee->file;
               unlink($file_old);
          }

          //upload new file
          $file = $request->file;
          $filename = $file->getClientOriginalName();
          $file->move($path, $filename);

          //for update in table
          $employee->update(['file' => $filename]);
     }
}
