提交表单后，我得到 "Method Illuminate\Validation\Validator::validate255 does not exist."

Question

提交表单后，我收到此错误 "Method Illuminate\Validation\Validator::validate255 does not exist."，

我已经检查了我验证过的功能，甚至找不到问题所在？

这是我的第一个商店功能：

 public function store(Request $request)
{
    // Validate form

    $this->validate($request, [
        'name' => 'required|255',
        'email' => 'required|email|unique:users'
    ]);

    // Generate password
    if(Request::has('password') && !empty($request->password)){
        $password = trim($request->password);
    } else{
        # set the manual password
        $length = 10;
        $keyspace = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';
        $str = '';
        $max = mb_strlen($keyspace, '8bit') - 1;

    for ($i = 0; $i < $length; ++$i) {
        $str .= $keyspace[random_int(0, $max)];
    }
        $password = $str;
    }

    $user = new User();

    // Insert User's data into database
    $user->name = $request->name;
    $user->email = $request->email;
    $user->password = Hash::make($password);


    if($user->save()){
        return redirect()->route('users.show', $user->id);
    } else{
        Session::flash('danger', 'Sorry, a problem occured while creating this user.');
        return redirect()->route('users.create');
    }

}

而且，这里是编辑用户的更新功能：

public function update(Request $request, $id)
{
    $this->validate($request, [
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users,email,'.$id
    ]);

    $user = User::findOrFail($id);
    $user->name = $request->name;
    $user->email = $request->email;

    if($request->password_options == 'auto'){
        # set the manual password
        $length = 10;
        $keyspace = '123456789abcdefghijkmnopqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ';
        $str = '';
        $max = mb_strlen($keyspace, '8bit') - 1;

    for ($i = 0; $i < $length; ++$i) {
        $str .= $keyspace[random_int(0, $max)];
    }
        $password = $str;

    } elseif($request->password_options == 'manual'){
        $user->password = Hash::make($request->password);
    }

    if($user->save()){
        return redirect()->route('users.show', $id);
    } else{
        Session::flash('danger', 'There was a problem saving the updated user info to the database. Please, try again.');
        return redirect()->route('users.edit', $id);
    }
}

我不认为前端有问题，但如果可以的话，我会更新 post。

Answer 1

机会 'name' => 'required|255', 到 'name' => 'required|max:255',

Answer 2

您对名称的验证存在问题。

您可以使用以下代码更改您的验证码。

   $this->validate($request, [
        'name' => 'required|max:255',
        'email' => 'required|email|unique:users'
    ]);

您可以使用下面的 link 检查可用的 laravel 验证： https://laravel.com/docs/5.6/validation#available-validation-rules

提交表单后，我得到 "Method Illuminate\Validation\Validator::validate255 does not exist."

After submitting a form, I get "Method Illuminate\Validation\Validator::validate255 does not exist."
