Laravel中的表单构建和验证：简化用户输入和数据处理

<form action="/register" method="POST">
    @csrf
    <label for="name">姓名:</label>
    <input type="text" name="name" id="name" value="{{ old('name') }}"><br>
  
    <label for="email">邮箱:</label>
    <input type="email" name="email" id="email" value="{{ old('email') }}"><br>
    
    <label for="password">密码:</label>
    <input type="password" name="password" id="password"><br>
    
    <label for="confirm_password">确认密码:</label>
    <input type="password" name="confirm_password" id="confirm_password"><br>
    
    <input type="submit" value="注册">
</form>

public function register(Request $request)
{
    $validatedData = $request->validate([
        'name' => 'required',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:6|confirmed',
    ]);
    
    // 在此处进行用户注册逻辑...
}

public function register(Request $request)

    $validatedData = $request->validate([
        'name' => 'required',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:6|confirmed',
        'phone' => 'required|valid_phone_number',
    ]);

    // 在此处进行用户注册逻辑...
}

Validator::extend('valid_phone_number', function ($attribute, $value, $parameters, $validator) {
    return preg_match('/^[d]{11}$/', $value);
});
