Php 删除上传的个人资料图片并重置为laravel问题中的默认图像

我有一张带有用户照片的用户更新表。目前，我正在用户表的propic列中保存我的用户照片（文件名）

问题

当用户想要删除上传的图像时，我试图添加一个删除照片按钮。用户单击RemovePhoto按钮后，需要将用户的propic列值重置为默认值（user photo.png）。我只需要为更新个人资料照片的用户显示“删除照片”按钮。具有默认个人资料照片的用户不需要此选项

我到目前为止所做的事情

这是我的表单，在用户刀片中

首先，您需要在视图中检查用户配置文件照片是否为“user photo.png”，如果为true，请插入一个按钮以重置照片：

@if($user->propic != 'user-photo.png')
    <button type="submit" name="resetphoto" class="btn btn-warning">Reset Profile Pic</button>
@endif

我假设你的“$设置”是用户模型

@if($user->propic != 'user-photo.png')
    <button type="submit" name="resetphoto" class="btn btn-warning">Reset Profile Pic</button>
@endif

if ($request->has('resetphoto')){
    $setting->propic = 'user-photo.png';
    $setting->update();
    return Redirect::back()->with('success',__('sentence.User profile pic reset successfully'));
}
