无法打印所需数据

Question

我正在尝试使用多个if语句

打印所需的数据

$event_date = '2015-11-16';
//print_r($event_date);
$daily_info = array();
$buk_data = array();

$bw_daily_data = db_query('select * from potli_booking where buk_date   =:buk_date order by refno',array(':buk_date' => $event_date));

foreach($bw_daily_data as $daily_data) {
    $waitlist = $daily_data->waitlist;
    $noshow = $daily_data->noshow;
    $seated = $daily_data->seated;
    if($waitlist == '0' && $noshow == 'no' && $seated == 'NULL') {
        $daily_info['data'][]=array(
            'firstname' =>$daily_data->fname,
            'lastname' => $daily_data->lname,
            'time'=>$daily_data->time,
            'status'=>'overdue  arrival'
        );
    }
    else if($waitlist == '1' && $noshow == 'no' && $seated == 'NULL') {
        $daily_info['data'][]=array(
            'firstname' =>$daily_data->fname,
            'lastname' => $daily_data->lname,
            'time'=>daily_data->time,
            'status'=>'Wait list'
        );
    }
    else if ($waitlist == '0' && $noshow == 'yes' && $seated == 'NULL') {
        $daily_info['data'][]=array(
            'firstname' =>$daily_data->fname,
            'lastname' => $daily_data->lname,
            'time'=>daily_data->time,
            'status'=>'No show'
        );
    }
    else {
        $daily_info['data'][]=array(
            'firstname' =>$daily_data->fname,
            'lastname' => $daily_data->lname,
            'time'=>daily_data->time,
            'status'=>'seated'
        );
    }
}
print_r($daily_info);

但它只打印就座数据。帮我解决这个问题
