Question

I have an array of collection named $configurations. This array matches of my Entity Configuration.php connected to Product.php as a

Answer 1

I had the same problem with Doctrine2 recently and I came with that answer.

If you want all Product entities that are linked with all the configurations, you need to add a where condition for every configuration.

Considering your $configurations variable is an array of Configuration entities

$queryBuilder->select('p')
             ->from('MyBundle', 'p')
             ->join('p.workType', 'wt', 'WITH', 'wt.id = p.workType')
             ->leftJoin('p.configurations','c');

$queryBuilder->where('wt.slug = :slug')->setParameter('slug', $slug);

$nbConfs = count($configurations);
  for($i = 0; $i < count($configurations); $i++){
      $queryBuilder->andWhere(":conf{$i} MEMBER OF p.configurations")->setParameter("conf{$i}", $configurations[$i]);
  }

$queryBuilder
      ->having('COUNT(c.id) =:some_count')
      ->setParameter('some_count', $nbConfs);

I had to use a for loop to create different tokens (the string preceded by :), otherwise Doctrine doesn't add them to its internal collection of parameters.

Edit : Query modified to consider the case where you pass no configurations and want to get Products that has no relations to Configurations.
