Php 如果不工作，则需要Laravel\u

如果验证不起作用，我需要的\u。选择“双人”但未选择“队友2和对手2”时，不会输出错误。当双打被选为比赛类型时，我需要表格来要求另一个队友和对手

Match.php（模型）

匹配创建视图

        {{ Form::open(array('url'=>'members/matches/create', 'action' => 'post', 'class'=>'form-horizontal')) }}

当我不使用这样的模型时：

$validator = Validator::make(
    array('match_type' => Input::get('match_type')),
    array('opponent' => 'required_if:match_type,doubles')
);

这似乎奏效了。我仍然不确定为什么我的方法不起作用，如果在模型中，匹配类型值是否不会传递到必需类型

        {{ Form::open(array('url'=>'members/matches/create', 'action' => 'post', 'class'=>'form-horizontal')) }}
        {{ form::hidden('id', Auth::user()->id) }}
