Laravel查詢生成器中的複雜查詢

Question

我在我的網站中創建了搜索功能。不過，我的舊查詢引入了deleted_at列，儘管它們爲空。

所以我寫了原始MySQL的查詢，並得到我期待的結果。

但是，我正在努力使用Laravel的查詢生成器來寫這個。工作MySQL查詢我想的是：

select * from `packs` 
left join `keywords` 
on `keywords`.`pack_id` = `packs`.`pack_id` 
inner join `categories` 
on `categories`.`category_id` = `packs`.`primary_category_id` 
left join `ratings` 
on `ratings`.`pack_id` = `packs`.`pack_id` 
where (`pack_title` LIKE '%sams%' 
or `keywords`.`keyword_title` LIKE '%sams%') 
and `packs`.deleted_at is null 
group by `pack_title` 
order by `packs`.`created_at` 
desc 

我使用Laravel當前的嘗試看起來像這樣：

// Explode Terms 
      $terms = explode(' ', $q); 

      // Produce Query (Initially) 
      $query = DB::table('packs') 
         ->leftJoin('keywords', 'keywords.pack_id', '=', 'packs.pack_id') 
         ->leftJoin('categories', 'categories.category_id', '=', 'packs.primary_category_id') 
         ->whereNotNull('packs.deleted_at') 
         ->leftJoin('ratings', 'ratings.pack_id', '=', 'packs.pack_id'); 

      // Loop through each term 
      foreach($terms as $term) 
      { 
       $query->where('pack_title', 'LIKE', '%'. $term . '%') 
         ->orWhere(function($query, $term) 
         { 
          $query->orWhere('pack_description', 'LIKE', '%'. $term . '%') 
           ->orWhere('keywords.keyword_title', 'LIKE', '%'. $term . '%'); 
         }) 
         ->whereNotNull('packs.deleted_at') 
         ->groupBy('pack_title') 
         ->orderBy('packs.created_at', 'DESC'); 

      } 

      // Log 
      Log::info('User Searched using term : '.$q.''); 

      $results = $query->get(); 

這是產生錯誤：

缺少論據2 SearchesController :: {closure}（）

這是可以寫查詢構建呃，如果是這樣的話。如果需要，我不介意將它編寫爲RAW查詢。

感謝

試試這個：

$terms = explode(' ', $q); 

// Produce Query (Initially) 
$query = DB::table('packs') 
     ->leftJoin('keywords', 'keywords.pack_id', '=', 'packs.pack_id') 
     ->leftJoin('categories', 'categories.category_id', '=', 'packs.primary_category_id') 
     ->whereNotNull('packs.deleted_at') 
     ->leftJoin('ratings', 'ratings.pack_id', '=', 'packs.pack_id'); 

// Loop through each term 
foreach($terms as $term) 
{ 
    $query->where('pack_title', 'LIKE', '%'. $term . '%') 
      ->orWhere(function($query) use ($term) 
    { 
     $query->orWhere('pack_description', 'LIKE', '%'. $term . '%') 
       ->orWhere('keywords.keyword_title', 'LIKE', '%'. $term . '%'); 
    }) 
    ->whereNotNull('packs.deleted_at') 
    ->groupBy('pack_title') 
    ->orderBy('packs.created_at', 'DESC'); 
} 

// Log 
Log::info('User Searched using term : '.$q.''); 
$results = $query->get(); 

注：我在這裏->orWhere(function($query) use ($term)
