Retrieving data from database and passing it as instance of entity - php

Question

I'm trying to pass id from query from one database table to another table to which is related.
But, since they are related I have to pass it as instance of the entity(class) to which is related.
This is error I got:
Argument 1 passed to App\Entity\KeywordRating::setKeywordId() must be an instance of App\Entity\Keywords, integer given, called in C:\xampp\htdocs\ratingAPI\src\Service\KeywordRatingService.php on line 26
This is my code:
public function insertRating($params, ObjectManager $manager, KeywordsRepository $keyRep, ProvidersRepository $provRep)
{
$keywordId = $keyRep->checkKeyword(strtolower($params['keyword']))->getId();
$providerId = $provRep->checkProvider($params['provider'])->getId();
$rating = new KeywordRating();
$rating->setKeywordId(<Keywords instance> $keywordId);
$rating->setProviderId(<Providers instance> $providerId);
if($params['attr'] === 'rocks')
{
$rating->setRocksRating($params['rating']);
$rating->setSucksRating(0);
} else
{
$rating->setRocksRating(0);
$rating->setSucksRating($params['rating']);
}
$rating->setRocksVotes(10);
$rating->setSucksVotes(8);
$rating->setSumVotes(18);
$rating->setScore(2.50);
$manager->persist($rating);
$manager->flush();
}
This is sql query:
public function checkKeyword($keyword)
{
return $this->createQueryBuilder('k')
->where('k.keyword_name = :val')
->setParameter('val', $keyword)
->getQuery()
->getOneOrNullResult();
}
checkProvider() is the same, only different parameters.
How do I do that?

Assuming you have a namespace called Entities where you have all your entities classes, you can try something like this:
$entityManager = $this->getDoctrine()->getManager();
$queryBuilder = $entityManager->createQueryBuilder();
$queryBuilder->select('keyword')
->from('App\Entity\Keywords', 'keyword')
->where($queryBuilder->expr()->eq('keyword.keyword_name', $queryBuilder->expr()->literal($keyword)));
$result = $queryBuilder->getQuery()-> getOneOrNullResult();
return $result;
