Custom FIlter that matches two fields - symfony

Question

I simply want an API endpoint that matches two fields, registrationId and hash.
I cannot find any examples of this online, I can only single matches, regex matching, OR clauses etc. Nowhere is there an example of just just querying the database to return a row that matches two columns.
I have a table called registrationhashes. In the entity I have added this line:
#[ApiFilter(RegistrationSearchFilter::class, properties: ['registrationId', 'hash'])]
And then I have gotten so far with writing a custom filter:
final class RegistrationSearchFilter extends AbstractFilter
{
protected function filterProperty(string $property, $value, QueryBuilder $queryBuilder, QueryNameGeneratorInterface $queryNameGenerator, string $resourceClass, Operation $operation = null, array $context = []): void
{
if ($property !== 'search') {
return;
}
$alias = $queryBuilder->getRootAliases()[0];
$queryBuilder->andWhere(sprintf('%s.registrationId = :search AND %s.hash = :hash', $alias, $alias));
}
public function getDescription(string $resourceClass): array
{
if (!$this->properties) {
return [];
}
$description = [];
foreach ($this->properties as $property => $strategy) {
$description["regexp_$property"] = [
'property' => $property,
'type' => Type::BUILTIN_TYPE_STRING,
'required' => false,
'description' => 'Filter using a regex. This will appear in the OpenApi documentation!',
'openapi' => [
'example' => 'Custom example that will be in the documentation and be the default value of the sandbox',
'allowReserved' => false,// if true, query parameters will be not percent-encoded
'allowEmptyValue' => true,
'explode' => false, // to be true, the type must be Type::BUILTIN_TYPE_ARRAY, ?product=blue,green will be ?product=blue&product=green
],
];
}
return $description;
}
}
I have just put the description function in there copied from somewhere else for now.
But as you can see from the WHERE clause I ned to match registrationId AND hash, but I only have one value to match with.
How can I achieve this?

Look at the search filter docs, you will see an example of combining two search filters. I believe this accomplishes your task without the need for a custom filter.
use ApiPlatform\Doctrine\Orm\Filter\SearchFilter;
#[ApiResource]
#[ApiFilter(SearchFilter::class, properties: ['registrationId' => 'exact', 'hash' => 'exact'])]
class RegistrationHash
{
// ...
}
The endpoint would then be something like:
http://localhost:8000/api/registrationhashes?registrationId=10&hash=3C76B43F
