Using multiple ->setParameters in Symfony2 Query builder

Question

I'm adding filters to my query builder but I'm getting an html 500 error when using both filters at the same time. One only one of them it works fine.

Simplified query code:

$query = $this->createQueryBuilder('a')
              ->select('a.id')
              ->where('a.active = 1');

        if($year) {        
            $year = explode('-', $year);

            $query->andWhere('a.minYear >= :min AND a.year <= :maxYear')
                ->setParameters(array('minYear'=> $year[0], 'maxYear' => $year[1]));
        }

        if($hours) {
            $hours = explode('-', $hours);

            $query->andWhere('a.hours >= :minHours AND a.hours <= :maxHours')
            ->setParameters(array('minHours'=> $hours[0], 'maxHours' => $hours[1]));
        }

       return $query->getQuery()->getResult();

Answer 1

First of all you have a wrong parameter min and minYear .

Secondly you should use setParameter method instead of setParameters . setParameters creates a new parameters collection and override existing one each time you call it. That is why:

    if($year) {        
        $year = explode('-', $year);

        $query->andWhere('a.minYear >= :minYear AND a.year <= :maxYear')
            ->setParameter('minYear', $year[0])
            ->setParameter('maxYear', $year[1]);
    }

    if($hours) {
        $hours = explode('-', $hours);

        $query->andWhere('a.hours >= :minHours AND a.hours <= :maxHours')
            ->setParameter('minHours', $hours[0])
            ->setParameter('maxHours', $hours[1]);
    }
