存储磁盘从数据库删除映像

Question

当我尝试从db删除图像时出现此错误： 未定义的变量：removeslider

public function delete($id){
     $getslider = DB::table('slider')->where('id',$id)->get();
     foreach($getslider as $getslider) {
     $removeslider = $getslider->bgimage;
     }
        Storage::disk('uploadssliders')->delete($removeslider);
        return redirect('admin/inicio');
   }

Answer 1

尝试一下：

public function delete($id)
{
    $getslider = DB::table('slider')->where('id',$id)->first();
    if($getslider){
         Storage::disk('uploadssliders')->delete($getslider->bgimage);
         return redirect('admin/inicio');
    } else {
         //id has no match in the database
         echo "the id ". $id . " does not exist";
    }  
}

我将您的get()更改为first()只能得到一个结果，因为这似乎是您要尝试执行的操作，因此不需要foreach。
