select specific Columns with createQueryBuilder in Doctrine ORM using Parameters

Question

$qb = $this->em->createQueryBuilder()
    ->select("p.$input")
    ->from('AppBundle:Profile', 'p')
    ->where("p.$input LIKE :value")
    ->setParameter('value', '%'.$value.'%')
    ->setMaxResults(5);

$results = $qb->getQuery()->execute();
$response['results'] = $results;

is there a way to even set the $input using setParameter ?

Answer 1

I am doing this in that way:

class EntityHelper{
    /**
     * @param Object $entity
     * 
     * @return array
     */
    public static function entityToArray($entity) {
        $className = "\0" . get_class($entity) . "\0";
        $entityAsArray = (array)$entity;
        $retArray = array();
        foreach ($entityAsArray as $key => $val) {
            $retArray[str_replace($className, '', $key)] = $val;
        }
        return $retArray;
    }

    /**
     * @param Object $entity
     * @param string $parameter
     *
     * @return boolean
     */
    public static function checkEntityHasParameter($entity, $parameter) {
        return array_key_exists($parameter, self::entityToArray($entity));
    }
}

Use checkEntityHasParameter static method to check that field will occur in your table.

WARNING! It works only with standard type fields, and sometimes when mapping were used.
