Question

I have a Syfmony2 app with a table which has a date field. This date field is a DateTime type.

I need to get all the entities which the same date as now.

But

Answer 1

Method in repository

public function getDays(\DateTime $firstDateTime, \DateTime $lastDateTime)
{
    $qb = $this->getEntityManager()->createQueryBuilder()
        ->select('c')
        ->from('ProjectBundle:Calendar', 'c')
        ->where('c.date BETWEEN :firstDate AND :lastDate')
        ->setParameter('firstDate', $firstDateTime)
        ->setParameter('lastDate', $lastDateTime)
    ;

    $result = $qb->getQuery()->getResult();

    return $result;
}

And action

public function calendarAction()
{
    $currentMonthDateTime = new \DateTime();
    $firstDateTime = $currentMonthDateTime->modify('first day of this month');
    $currentMonthDateTime = new \DateTime();
    $lastDateTime = $currentMonthDateTime->modify('last day of this month');

    $days = $this->getDoctrine()
        ->getRepository('ProjectBundle:Calendar')
        ->getDays($firstDateTime, $lastDateTime);

    return ['days' => $days];
}
