Doctrine DQL conditional query

Question

I\'m trying to build a dynamic query with Doctrine\'s query builder. Let\'s say I\'d also like to optionally select an end time in the following (only if one was entered). H

Answer 1

I'd do something like this:

// first, create the query builder
$qb = $this->getEntityManager()->createQueryBuilder()
    ->select('m')
    ->from($this->getEntityName(), 'm')
;

// add the default condition
$conditions = array(
    $qb->expr()->gt('m.start', date('Y-m-d H:i:s', strtotime($start)));
);

// put your condition here
if (isset($end)) {
    $conditions[] = $qb->expr()->lt('m.end', date('Y-m-d H:i:s', strtotime($end)));
}

// convert the conditions to an AND clause
$conditions = call_user_func_array(array($qb, 'andX'), $conditions);

// add the WHERE clause
$qb->where($conditions);

// get the query
$query = $qb->getQuery();
