Php Laravel文件名数据库

在

Laravel 5.3

中，我上传的文件如下：

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);
        }
    }
}

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);
        }
    }
}

所以它是这样存储的：

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);
        }
    }
}

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);
        }
    }
}

如何存储随机名称（路径）而不是整个路径

（随机唯一名称，如：

）

}我是这样做的：

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);
        }
    }
}

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);
        }
    }
}

您需要一些随机函数来生成随机名称并调用该函数来代替$directory“$fileName=$attachment->store（'users/'.$user->id./'.$directory）”；“现在它正在生成一个额外的文件夹。
