Question

我的required_if验证不起作用。选择“双打”但未选择“team_mate2和opponent2”时不输出错误。当选择双打作为比赛类型时，我需要表格要求第二队友和对手。

Match.php（模型）

<?php

class Match extends Eloquent{

    protected $table = 'matches';

    public static $rules = array(
        'match_type'=>'required',
        'associate'=>'alpha|min:2',
        'location'=>'required|alpha|min:2',
        'opponent'=>'numeric',
        'team_mate2'=>'required_if:match_type,doubles',
        'opponent2'=>'required_with:team_mate2'
    );

    public static $messages = array(
        'opponent.numeric'=>'You must select a player.'
    );

}

MatchController.php

public function postCreate()
{

    $validator = Validator::make(Input::all(), Match::$rules, Match::$messages);

    if ($validator->passes()) 
    {

        $datetime = Input::get('year')."-".Input::get('month')."-".Input::get('day')." ".Input::get('time').":00";

        $match = new Match;
        $match->type = Input::get('match_type');
        $match->associate = Input::get('associate');
        $match->date = $datetime;
        $match->location = Input::get('location');
        $match->save();

        $matchp1 = new Matchplayer;
        $matchp1->user_id = Input::get('id');
        $matchp1->match_id = $match->id;
        $matchp1->team = 1;
        $matchp1->save();

        $matchp2 = new Matchplayer;
        $matchp2->user_id = Input::get('opponent');
        $matchp2->match_id = $match->id;
        $matchp2->team = 2;
        $matchp2->save();

        return Redirect::to('members/matches/create')->with('message', 'Match created!');

    }else{
        return Redirect::to('members/matches/create')->withErrors($validator)->withInput();
    }
}

匹配创建视图

        {{ form::hidden('id', Auth::user()->id) }}

Answer 1

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')
);

这似乎有效。我仍然不确定为什么我的方法不起作用，在模型中，match_type值是不是会传递给required_if？

Laravel required_if不起作用
