嘿伙计们，我正在尝试添加验证规则以仅接受字母。我正在使用该regex规则，但它仍然无法正常工作。下面是我的代码
/**
* Validate request/input

$this->validate($request, [
'name' => 'required|regex:/^[\pL\s\-]+$/u|max:255|unique:users,name,'.$user->id,
'email' => 'required|email|max:255|unique:users,email,'.$user->id,
]);
Whenever i enter a name like Foo Fooits still succesful in signing up.
每当我输入一个名字时，Foo Foo它仍然会成功注册。

Your regex fails I think, I tried it on Regexrand couldn't get it to function, try this:
我认为您的正则表达式失败了，我在Regexr上尝试过但无法使其正常运行，请尝试以下操作：
'name' => 'required|regex:/^[a-zA-Z]+$/u|max:255|unique:users,name,'.$user->id,
Let me know how you get on.
让我知道你是怎么办的。
Here's the regex only: ^[a-zA-Z]+$
这里只有正则表达式：^[a-zA-Z]+$

According to laravel documentationyou can use :
根据laravel文档，您可以使用：
alphafor entirely alphabetic charactersalpha_dashfor alpha-numeric characters, as well as dashes and underscores and finallyalpha_numfor entirely alpha-numeric characters.
alpha对于完全字母字符alpha_dash对于字母数字字符，以及破折号和下划线，最后alpha_num对于完全字母数字字符。
