Thats the way i do it always for other things:
这就是我总是为其他事情做的方式：
->uniqueid = 'VA'.str_random(28);
how can i add it to my Controller for image name? And how can i use only alphabetic character not numbers? Or i must change my DB Table.
我如何将它添加到我的控制器以获取图像名称？我怎样才能只使用字母字符而不使用数字？或者我必须更改我的数据库表。

Try this:
尝试这个：
public function MyPicture(Request $request){
$user = Auth::user();
$user->mypicture = date('mdYHis') . uniqid() . $request->mypicture;
$user->save();
return redirect()->back();
}
You can use Date (Y-m-d H:i:s) and uniqid()to generate unique name every file.
您可以使用 Date (Ymd H:i:s) 并uniqid()为每个文件生成唯一名称。

Laravel has an inbuilt method for this, using their File facade.
Laravel 有一个内置的方法，使用它们的 File 外观。
From laravel docs:
来自 Laravel 文档：
$path = $request->file('avatar')->store('avatars');
return $path;
By default, the store method will generate a unique ID to serve as the file name. The path to the file will be returned by the store method so you can store the path, including the generated file name, in your database.
默认情况下，store 方法会生成一个唯一的 ID 作为文件名。文件的路径将由 store 方法返回，因此您可以在数据库中存储路径，包括生成的文件名。

Do the same here:
在这里做同样的事情：
$user = Auth::user();
$user->mypicture = $request->mypicture;
$user->filename = str_random(28);
$user->save();
$request->mypicture->storeAs('images', $user->filename);
If you want to use only letters, use one of the existing solutions.
如果只想使用字母，请使用现有解决方案之一。
