可以按名字和姓氏搜索的控制器

Question

我正在尝试通过允许该控制器能够使用名字和姓氏进行搜索来使该控制器更加动态。目前，控制器仅按名字，姓氏和电子邮件地址进行搜索。我希望能够在过滤器“ $ filter =克里斯·史密斯”中输入并查询“克里斯·史密斯”的结果。

下面是我的控制器。

public function getEventSessionAttendeeAction(request $request, $eventSessionId) {

$filterName = 'filter';

$searchFields = [
    'o.email',
    'a.email',
    'a.firstName',
    'a.lastName',
    'a.barcode1',
    'a.barcode2',
    'a.id',
    'o.id',
    $lname = 'a.lastName',
    $fname = 'a.firstName'
];

$filter = $request->get('filter');
$match_level = 0;

   if ( filter_var($filter, FILTER_VALIDATE_EMAIL)) {
$searchFields = [
    'a.email'
];
$match_level = 1;

}elseif(preg_match('/^[a-zA-Z\-]*$/', $filter)){
  $searchFields = [
     'a.lastName',
     'a.firstName'
 ];
  $match_level = 2;
   }else{
   $lname = 'a.lastName';
   $fname = 'a.firstName';
   }



    try {
    /** @var ApiEntity\EventSession $eventSession */


    $em = $this->getDoctrine()->getManager();
    $qb = $em->createQueryBuilder();
       $qb ->select('a.firstName, a.lastName, a.relationship, a.dateOfBirth, a.barcode1, a.phoneNumber, ea.address1, ea.address2, ea.city, ea.state, ea.country, ea.postal, s.name, s.keynoteSpeaker, ci.created, \'checkin\' AS event')
        ->from('KCMApiBundle:EventSessionCheckin', 'ci')
        ->innerJoin('ci.eventSession', 's')
        ->innerJoin('ci.eventAttendee', 'a')
        ->leftJoin('a.eventAttendeeAddresses', 'ea')
        ->where($qb->expr()->andX(
           $qb->expr()->eq('ci.eventSession', $qb->expr()->literal($eventSessionId))
       ));



    $expr = $qb->expr()->orX();

    foreach ($searchFields as $field){
        if ($match_level === 1){
            $literalFilter = $filter;
            $expr->add($qb->expr()->like($field, $qb->expr()->literal($literalFilter)));
        }elseif ($match_level === 2){
            $literalFilter = $filter;
            $expr->add($qb->expr()->eq($field, $qb->expr()->literal($literalFilter)));
        }else{
            $literalFilter = $filter;
            $expr->add($qb->expr()->concat($lname, $qb->expr()->concat($qb->expr()->literal($literalFilter), $fname)));
        }
    }

    $qb->andWhere($expr);

    $results = $qb->getQuery()->getResult();

    if ($results) {

        return $this->getApi()->serialize($results);

    }

    return new Response(null, Response::HTTP_NOT_FOUND);

} catch (\Exception $e) {
    $this->get('logger')->error($e->getMessage());
}
}
