我使用Laravel雄辩的查询构建器,我有一个查询,我想在多个条件上有一个where子句。它能起作用,但并不优雅。

例子:

$results = User::where('this', '=', 1)
    ->where('that', '=', 1)
    ->where('this_too', '=', 1)
    ->where('that_too', '=', 1)
    ->where('this_as_well', '=', 1)
    ->where('that_as_well', '=', 1)
    ->where('this_one_too', '=', 1)
    ->where('that_one_too', '=', 1)
    ->where('this_one_as_well', '=', 1)
    ->where('that_one_as_well', '=', 1)
    ->get();

有没有更好的方法,或者我应该坚持这个方法?

使用这个

$users = DB::table('users')
                    ->where('votes', '>', 100)
                    ->orWhere('name', 'John')
                    ->get();

其他回答

public function search()
{
    if (isset($_GET) && !empty($_GET))
    {
        $prepareQuery = '';
        foreach ($_GET as $key => $data)
        {
            if ($data)
            {
                $prepareQuery.=$key . ' = "' . $data . '" OR ';
            }
        }
        $query = substr($prepareQuery, 0, -3);
        if ($query)
            $model = Businesses::whereRaw($query)->get();
        else
            $model = Businesses::get();

        return view('pages.search', compact('model', 'model'));
    }
}

多个where子句

    $query=DB::table('users')
        ->whereRaw("users.id BETWEEN 1003 AND 1004")
        ->whereNotIn('users.id', [1005,1006,1007])
        ->whereIn('users.id',  [1008,1009,1010]);
    $query->where(function($query2) use ($value)
    {
        $query2->where('user_type', 2)
            ->orWhere('value', $value);
    });

   if ($user == 'admin'){
        $query->where('users.user_name', $user);
    }

终于得到了结果

    $result = $query->get();

如果你的条件是这样的(匹配一个值),一个简单的更优雅的方式是:

$results = User::where([
         'this' => value,
         'that' => value,
         'this_too' => value,
          ...
      ])
    ->get();

但如果你需要OR子句,那么确保你对每个OR where()子句重复必须满足条件。

    $player = Player::where([
            'name' => $name,
            'team_id' => $team_id
        ])
        ->orWhere([
            ['nickname', $nickname],
            ['team_id', $team_id]
        ])
DB::table('users')
            ->where('name', '=', 'John')
            ->orWhere(function ($query) {
                $query->where('votes', '>', 100)
                      ->where('title', '<>', 'Admin');
            })
            ->get();

根据我的建议,如果你正在做筛选或搜索

那么你应该选择:

        $results = User::query();
        $results->when($request->that, function ($q) use ($request) {
            $q->where('that', $request->that);
        });
        $results->when($request->this, function ($q) use ($request) {
            $q->where('this', $request->that);
        });
        $results->when($request->this_too, function ($q) use ($request) {
            $q->where('this_too', $request->that);
        });
        $results->get();
