Question

我需要在一个中收集6个示波器，以便更轻松地使用它们。是否可以使用laravel？这是我使用它们的地方：

public function listSchoolsEndUser()
{
    $schools_data = new School;

    if ( Input::has('specialties') ) {
        $schools_data = $schools_data->whereSpecialties(Input::get('specialties'));
    }

    if ( Input::has('district') ) {
        $schools_data = $schools_data->whereDistrict(Input::get('district'));
    }

    if ( Input::has('municipality') ) {
        $schools_data = $schools_data->whereMunicipality(Input::get('municipality'));
    }

    if ( Input::has('city') ) {
        $schools_data = $schools_data->whereCity(Input::get('city'));
    }

    if ( Input::has('type') ) {
        $schools_data = $schools_data->whereType(Input::get('type'));
    }

    if ( Input::has('financing') ) {
        $schools_data = $schools_data->whereFinancing(Input::get('financing'));
    }

    $schools_data = $schools_data->paginate(12);

    return $schools_data;
}

我需要多次使用这些过滤器，并且我没有理由再次重复相同的代码。

编辑：我的示例范围范围

public function scopeWhereDistrict($query, $districts)
{
    if(! is_array($districts))
    {
        $districts = [$districts];
    }

    return $query->where(function($q) use ($districts)
    {
        foreach ($districts as $district)
        {
            $q->whereHas('city.municipality', function ($q) use ($district) {
                $q->where('district_id', '=', $district);
            });
        }
    });
}

循环浏览所有输入并添加where应该有效：

$schools_data = School::query();
$filters = Input::only('specialities', 'district', 'municipality', 'city', 'type', 'financing');

foreach($filters as $filter => $value){
   call_user_func(array($schools_data, 'where' . studly_case($filter)), $value);
}

return $schools_data->paginate(12);

Laravel Eloquent收集我的范围
