Question

我的Larvel Query出了问题，它根本无法正常工作。它应该使用“开始”和“结束”属性“团队”，“频道”，“区域”和“时间段”过滤“广告系列”。时间段没问题。用户可以过滤不同的团队/频道/区域，并且可以选择否，一个或多个属性，它们应该作为或连接。所需的结果应该为所有具有所选团队和频道AND区域的Campaign提供。但目前我得到的每个广告系列都有选定的小组或选定的频道或所选区域。

希望你能有人帮助我。

试试这个。它应该工作。如果发生任何问题，请告诉我:)）

public function searchCampaigns($page, $limit, $data)
{
    $result = [];     

    // Checking Validity of Start Date
    if (empty($data['startDate']) || (Carbon::createFromFormat('Y-m-d', $data['startDate']) === false))
        return $result;

    // Checking Validity of End Date                
    if (empty($data['endDate']) || (Carbon::createFromFormat('Y-m-d', $data['endDate']) === false))
        return $result;                 

    // Comparing Start & End Date
    $startDate = Carbon::parse($data['startDate']);
    $endDate = Carbon::parse($data['endDate']);

    if($startDate->gt($endDate))
        return $result;

    if($endDate->lt($startDate))
        return $result;

    $startDate = $data['startDate'];
    $endDate = $data['endDate'];                        

    $campaigns = Campaign::distinct()->select('campaigns.*')
                ->join('campaign_team', 'campaign_team.campaign_id', '=', 'campaigns.id')
                ->join('campaign_region', 'campaign_region.campaign_id', '=', 'campaigns.id')
                ->join('campaign_channel', 'campaign_channel.campaign_id', '=', 'campaigns.id')
                ->join('teams', 'campaign_team.team_id', '=', 'teams.id')
                ->join('regions', 'campaign_region.region_id', '=', 'regions.id')
                ->join('channels', 'campaign_channel.channel_id', '=', 'channels.id')
                ->whereIn('teams.id', $data['teams'])
                ->whereIn('regions.id', $data['regions'])
                ->whereIn('channels.id', $data['channels'])
                ->where('campaigns.start_date', '>=', $startDate)
                ->where('campaigns.end_date', '<=', $endDate);
                ->orderBy('start_date', 'asc');

    $result['count'] = sizeof($campaigns->lists('id'));
    $result['campaigns'] = $campaigns->skip($limit * ($page - 1))->take($limit)->get();

    return $result;
}
