这样Laravel文件名数据库

Question

在Laravel 5.3我上传文件：

public function upload(Request $request, User $user, $directory) 
{ 
    if($request->hasFile('attachment')) 
    { 
     $attachments = $request->file('attachment'); 
     foreach ($attachments as $attachment) { 
      $fileName = $attachment->store('users/' . $user->id . '/' . $directory); 
      $file = new File; 
      $file->path = $fileName; 
      $file->user_id = $user->id; 
      $this->files()->save($file); 
     } 
    } 
} 

所以它的存储是这样的：

如何存放一个随机名称（路径）而不是整个路径？

（随机唯一的名称类似：7b11ae012907b5811cb6985d39e16052）

Answer 1

public function upload(Request $request, User $user, $directory) 
{ 
if($request->hasFile('attachment')) 
{ 
    $random_name=rand(5, 15); 
    $attachments = $request->file('attachment'); 
    foreach ($attachments as $attachment) { 
     $fileName = $attachment->store('users/' . $user->id . '/' . $random_name); 
     $file = new File; 
     $file->path = $fileName; 
     $file->user_id = $user->id; 
     $this->files()->save($file); 
    } 
} 

}

我已经做了这样的：

public function upload(Request $request, User $user, $directory) 
{ 
    if($request->hasFile('attachment')) 
    { 
     $attachments = $request->file('attachment'); 
     foreach ($attachments as $attachment) { 
      $random = str_random(30); 
      $filename = $random . $attachment->getClientOriginalName(); 
      $attachment->storeAs('users/' . $user->id . '/' . $directory, $filename); 
      $file = new File; 
      $file->path = $filename; 
      $file->user_id = $user->id; 
      $this->files()->save($file); 
     } 
    } 
}
