Question

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) }}" >

                    @endif

如果没有上传图片，请从配置文件中获取图片这里的问题是，在$profile方法中注入的store()不是正确的方法，请直接从用户加载它。

public function store(Request $request, $id = null)
{
    $profile = auth()->user()->profile;

    if($request->hasFile('image')){
        //upload it
        $image = $request->image->store('profile');

        //delete old image
        if ($profile) {
            Storage::delete($profile->image);
        }
    } else {
        $image = $profile->image??null;
    }

    $profile->update(
        [
            'image' => $image,
            'gender' => request('gender'),
            'country' => request('country'),
            'bod' => request('bod'),
            'instagram' => request('instagram'),
            'description' => request('description'),
        ]);

    //flash message

    //redirect user
    return redirect()->route('profile.index');
}
