Using the same named parameter at various places within a DQL query will result in a PHP fatal error

Currently, I automatically post-process all queries so that all parameters are assigned new (unique) names. This way, even the multiple replicated subqueries within the same DQL query will end up having unique parameter names. While this works, it is clumsy as a general approach.

Works for me, see patch attached.

The error occuring to you is not related to named parameters but to objects as parameters. Can you give a reproducable test-case to fix this?

OK, I will see what I can do. I will prepare an example of a working scenario and a non-working scenario, and let you know.

I tried to reduce the non-working query as much as possible to get a schematic idea of what provokes the error.

It seems that queries like this one will break:

{{$doctrineQuery = $doctrineEntityManager->createQuery('SELECT a
FROM \persistentData\model\import\A a,
WHERE a.a = :anEntityInstance
AND a.b = :anEntityInstance
AND a.c = :aString');

$doctrineQuery->setParameter('anEntityInstance', $anEntityInstance); // Whatever entity instance
$doctrineQuery->setParameter('aString', $aString); // Some string-valued variable

$doctrineQuery->getResult();}}

Note that the first argument is an entity instance, and the second one a string. Both are non-null.

This gives:

Warning: array_combine(): Both parameters should have an equal number of elements in /var/www/invoiceCreator/src/thirdPartyComponents/doctrine/Doctrine/ORM/Query.php on line 252 Fatal error: Unsupported operand types in /var/www/invoiceCreator/src/thirdPartyComponents/doctrine/Doctrine/ORM/Query.php on line 252

This is a basic form of a working scenario (all parameters have unique names):

{{$doctrineQuery = $doctrineEntityManager->createQuery('SELECT a
FROM \persistentData\model\import\A a,
WHERE a.a = :anEntityInstance1
AND a.b = :anEntityInstance2
AND a.c = :aString');

$doctrineQuery->setParameter('anEntityInstance1', $anEntityInstance); // Whatever entity instance
$doctrineQuery->setParameter('anEntityInstance2', $anEntityInstance); // Whatever entity instance
$doctrineQuery->setParameter('aString', $aString); // Some string-valued variable

$doctrineQuery->getResult();}}

Fixed.

Great, thanks.
