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?


当前回答

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]
        ])

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'));
    }
}

使用Array的条件:

$users = User::where([
       'column1' => value1,
       'column2' => value2,
       'column3' => value3
])->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and column2 = value2 and column3 = value3

使用匿名函数的条件:

$users = User::where('column1', '=', value1)
               ->where(function($query) use ($variable1,$variable2){
                    $query->where('column2','=',$variable1)
                   ->orWhere('column3','=',$variable2);
               })
              ->where(function($query2) use ($variable1,$variable2){
                    $query2->where('column4','=',$variable1)
                   ->where('column5','=',$variable2);
              })->get();

将产生如下查询:

SELECT * FROM TABLE WHERE column1 = value1 and (column2 = value2 or column3 = value3) and (column4 = value4 and column5 = value5)

使用Eloquent很容易创建多个where检查:

首先:(使用简单的where)

$users = User::where('name', $request['name'])
    ->where('surname', $request['surname'])
    ->where('address', $request['address'])
    ...
    ->get();

第二个:(在数组中分组where)

$users = User::where([
    ['name', $request['name']],
    ['surname', $request['surname']],
    ['address', $request['address']],
    ...
])->get();

你也可以在里面使用条件(=,<>,等等),就像这样:

$users = User::where('name', '=', $request['name'])
    ->where('surname', '=', $request['surname'])
    ->where('address', '<>', $request['address'])
    ...
    ->get();
$projects = DB::table('projects')->where([['title','like','%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])
->orwhere([['owner', 'like', '%'.$input.'%'],
    ['status','<>','Pending'],
    ['status','<>','Not Available']])->get();

你可以在几种情况下使用,

$results = User::where([
    ['column_name1', '=', $value1],
    ['column_name2', '<', $value2],
    ['column_name3', '>', $value3]
])->get();

你也可以这样用,

$results = User::orderBy('id','DESC');
$results = $results->where('column1','=', $value1);
$results = $results->where('column2','<',  $value2);
$results = $results->where('column3','>',  $value3);
$results = $results->get();
