Laravel 5.1 Eloquent转义字符串参数(haveraw)

Question

我收到一个字符串参数,我想使用havingRaw:

我收到的字符串:

$searchString = Input::get('q');//example:party beach

我在不同的问题中发现我应该使用它来防止sql注入:

$searchStringEsc = DB::connection()->getPdo()->quote($searchString);

我遇到的问题是,当我用havingRaw插入我的查询时,因为我的字符串现在转义为`party beach`它返回null,但是当我插入未转义字符串时,它工作正常.

->havingRaw('search rlike replace("'.$searchStringEsc.'", " ", "|")')

还有另一种逃避原始参数的方法吗？谢谢

编辑 - 完整查询(我正在进行搜索查询,用户可以在其中输入城市名称,企业​​名称,标记到企业的任何标签等)

            $results = DB::table('events')
            ->leftJoin('event_tag', 'events.id', '=', 'event_tag.event_id')
            ->join('tags', 'tags.id', '=', 'event_tag.tag_id')
            ->join('establishments', 'establishments.id', '=', 'events.establishment_id')
            ->join('cities', 'establishments.city_id', '=', 'cities.id')
            ->leftJoin('artist_event', 'events.id', '=', 'artist_event.event_id')
            ->join('artists', 'artist_event.artist_id', '=', 'artists.id')
            ->leftJoin('event_music', 'events.id', '=', 'event_music.event_id')
            ->join('musics', 'musics.id', '=', 'event_music.music_id')
            ->select('events.id as evId', 'events.slug as evSlug', 'events.name as evName',
                'events.cover_path as estPath','establishments.establishment_type_id as estType',
                'establishments.name as estName', 'events.start_date as evStart', 'events.end_date as evEnd',
                'cities.name as ciName',
                DB::raw('CONCAT_WS(",",
                        GROUP_CONCAT(distinct tags.name),
                        GROUP_CONCAT(distinct artists.name),
                        GROUP_CONCAT(distinct cities.name),
                        GROUP_CONCAT(distinct events.name),
                        GROUP_CONCAT(distinct musics.name)
                        ) as search'))
            ->where('events.end_date','>=', DB::raw('NOW()'))
            ->where('establishments.is_active','=',1)
            ->groupBy('events.id')
            ->havingRaw('search rlike replace("'.$searchString.'", " ", "|")')
            ->orderBy('events.total_visited', 'desc')
            ->take(5)->get();

如果我把它留作$ searchString(未缩放的字符串),它工作正常.如果我将其更改为$ searchStringEsc(转义字符串),则返回null

您可以简单地使用查询绑定，因此替换

 ->havingRaw('search rlike replace("'.$searchString.'", " ", "|")')

和

->havingRaw('search rlike replace(?, " ", "|")', [$searchString])

它可以处理您所有的逃避需求（whereRaw也可以做到这一点）。just?意味着你有一个绑定参数（即$searchString）。
