                                ->innerJoin('i.category', 'c')
                                ->innerJoin('c.parentCategory', 'h')
                                ->andWhere('h.categoryGroup = :groupCategory')
                                ->setParameter(
                                    'groupCategory',
                                    $options['groupCategory']
                                );
                        } 
                ,
                )
            )

Hello. I want, under a certain condition $options['groupCategory'] == 3, so that the 'query_builder' option is not executed. There just wasn't such a thing.

Answer 1

Make the form without the `marker` field, and add it on the FormEvents::PRE_SET_DATA event when the necessary conditions match.
See symfony.com/doc/current/cookbook/form/dynamic_form...

Answer 2

if .... else doesn't work anymore?

'query_builder' =>  function (EntityRepository $er) use ($options) {
                            if ($options['groupCategory'] == 3) {
                                 return $er->createQueryBuilder('x');
                            }
                            return $er->createQueryBuilder('x')
                                ->innerJoin('x.item', 'i')
                                ->innerJoin('i.category', 'c')
                                ->innerJoin('c.parentCategory', 'h')
                                ->andWhere('h.categoryGroup = :groupCategory')
                                ->setParameter(
                                    'groupCategory',
                                    $options['groupCategory']
                                );
                        }
