这个laravel的语法错误怎么写才对?
protected function validator(array $data)
{
return Validator::make($data, [
'name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|confirmed|min:6',
]);
}
因为增加了一项验证码,所以变成这样:
1、加了一个Request $request
参数;
2、加了一行代码$verification_code_session = $request->session()->get('verification_code', '');
)
protected function validator(array $data,Request $request)
{
$verification_code_session = $request->session()->get('verification_code', '');
return Validator::make($data, [
'name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|confirmed|min:6',
'verification_code' => 'required|in:' . $verification_code_session
]);
错误信息如下:
Type error: Argument 2 passed to App\Http\Controllers\Auth\AuthController::validator() must be an instance of Illuminate\Http\Request, none given, called in D:\wnmp\www\laravel-entrust\vendor\laravel\framework\src\Illuminate\Foundation\Auth\RegistersUsers.php on line 69
总之就是参数语法不对之类的问题,不知道语法怎么写,大神帮看一下。
回复内容:
用laravel5.2自带的注册表单,给它添加一个验证码项,和原表单一起提交验证,控制器的验证方法原来是这样的:
protected function validator(array $data)
{
return Validator::make($data, [
'name' => 'required|max:255',
'email' => 'required|email|max:255|unique:users',
'password' => 'required|confirmed|min:6',
]);
}

{
$verification_code_session = $request->session()->get('verification_code', '');
return Validator::make($data, [

'password' => 'required|confirmed|min:6',

]);

不要用依赖注入的方式注入Request类
直接这样
$verification_code_session = Request::session()->get('verification_code', '');
手机撰写,理解意思就行
除了可以静态调用Request::session()
(Facade)以及直接调用request()->session()
(helper)外,如果一定要用依赖注入的话,你必须把需要依赖注入的参数放到括号的前边,像下边这样:
protected function validator(Request $request, array $data)
{
//...
}
