仅在与雄辩的

Question

我有一个雄辩的查询，看起来像这样：

return $contest->join('posts','contests.id','posts.contest_id')
                    ->join('winners', 'contests.winner_id', 'winners.id')
                    ->where('posts.user_id', $id)
                    ->where('winners.gold_user_id', $id)
                    ->orWhere('winners.silver_user_id', $id)
                    ->orWhere('winners.bronze_user_id', $id)
                    ->orderBy('contests.created_at', 'desc');

在SQL中：

select * from `contests` 
    inner join `posts` on `contests`.`id` = `posts`.`contest_id` 
    inner join `winners` on `contests`.`winner_id` = `winners`.`id` 
    where `posts`.`user_id` = 4 
    and `winners`.`gold_user_id` = 4
    or `winners`.`silver_user_id` = 4 
    or `winners`.`bronze_user_id` = 4 
    order by `contests`.`created_at` desc

但是我的问题是，它显示找到ID的所有其他比赛条目。

这是我的获胜者表：

我要检查的是用户是否是金牌，银牌或铜牌的赢家。现在，通过我的查询，它将选择ID行匹配的所有列。我该如何实现自己的目标？

Answer 1

将OR conditions放在括号中-如下所示

select * from `contests` 
    inner join `posts` on `contests`.`id` = `posts`.`contest_id` 
    inner join `winners` on `contests`.`winner_id` = `winners`.`id` 
    where `posts`.`user_id` = 4 
    and (`winners`.`gold_user_id` = 4
    or `winners`.`silver_user_id` = 4 
    or `winners`.`bronze_user_id` = 4)
    order by `contests`.`created_at` desc

OP ELOQUENT QUERY

return $contest->join('posts','contests.id','posts.contest_id')
                    ->join('winners', 'contests.winner_id', 'winners.id')
                    ->where('posts.user_id', $id)
                    ->where(function($query) use ($id) {
                        $query->where('winners.gold_user_id', $id)
                                ->orWhere('winners.silver_user_id', $id)
                                ->orWhere('winners.bronze_user_id', $id);
                    })
                    ->orderBy('contests.created_at', 'desc');
