我正在laravel项目中创建配置文件编辑功能。

我想更新个人资料图片。当我上传新图像时，我可以在profile / index.blade.php中看到一个新图像。

但是，当我没有上传图像时，在profile / index.blade.php中看不到任何图像。我看到一个错误

  

在null上调用成员函数store（）   

配置文件编辑页面是profile / create.blade.php。然后，当我点击保存按钮时，我可以重定向到个人资料页面profile / index.blade.php。

我想完成的是，

  

当我上传新图像时，我想在   index.blade.php。如果我不上传图片，我想重定向到   index.blade.php并显示以前的个人资料图片。

我的存储中有个人资料文件夹。我已经完成了php artisan storage：link。

index.blade.php

<div class="person">
                    @if(empty(Auth::user()->profile->image))
                    <img src="{{asset('image/image1.jpg')}}" >
                    @else

                    <img src="{{ asset('storage/'.Auth::user()->profile->image) }}" >
