Question

这是我的SQL查询

select * from users us join EmailBox em on us.userid = em.suserid 
where em.status = "Delete" and (em.suserid="$userid" or em.riemailid="$user")

如果＆＃34; suserid＆＃34;我想检查任何一个字段。或＆＃34; riemailid＆＃34;只有结果。所以我在laravel querybuilder中改变了这个。

$lists = EmailBox::join('users as us', 'EmailBox.suserid', '=', 'us.id')
                ->where('status' , 'Delete')
                ->where(function($query){
                 $query->where('suserid' , '$userid');
                 $query->orwhere('riemailid' , '$user');    
        })->paginate(5);

当直接传递值时，此查询正常工作， userid直接传递1个手段

$lists = EmailBox::join('users as us', 'EmailBox.suserid', '=', 'us.id')
                    ->where('status' , 'Delete')
                    ->where(function($query){
                    $query->where('suserid' , 1);
                    $query->orwhere('riemailid' , '$user'); 
        })->paginate(5);

这是我在laravel中的代码。什么是错误？

    if(Auth::check()){
        //if(Auth::user()->email!="")
        $user=Auth::user()->email;
        $userid=Auth::user()->id;
        $lists = EmailBox::join('users as us', 'EmailBox.suserid', '=', 'us.id')
                            ->where('status' , 'Delete')
                            ->where(function($query){
                                $query->where('suserid' , '$userid');
                                $query->orwhere('riemailid' , '$user'); 
                            })->paginate(5);
        $links = $lists->render();
        return view('front.index', compact('lists', 'links'));
    }

我收到错误$ userid变量未定义。

Answer 1

->where(function($query) use($userid, $user){
    $query->where('suserid' , $userid);
    $query->orwhere('riemailid' , $user); 
}

Answer 2

您需要在查询中使用“use”关键字。

还要写下如下查询： -

EmailBox::join('users as us', 'EmailBox.suserid', '=', 'us.id')
          ->where('status' , 'Delete')
          ->where(function($query) use ($userid, $user){
              $query->where('suserid' , $userid)
                    ->orwhere('riemailid' , $user); 
          })->paginate(5);

希望它会对你有所帮助:)。

确保变量不写入＆＃39;＆＃39; （单引号）

 if(Auth::check()){
        //if(Auth::user()->email!="")
        $user=Auth::user()->email;
        $userid=Auth::user()->id;
        $lists = EmailBox::join('users as us', 'EmailBox.suserid', '=', 'us.id')
                            ->where('status' , 'Delete')
                            ->where(function($query){
                                $query->where('suserid' , $userid);
                                $query->orwhere('riemailid' , $user); 
                            })->paginate(5);
        $links = $lists->render();
        return view('front.index', compact('lists', 'links'));
    }
