Question

I have a problem, I want to filter the output data in this entity type I found a solution but I should change the value of searchterm inside the script,

$builder->add('userInput', EntityType::class, [
                'class' => User::class,
                'query_builder' => function(EntityRepository $er) use ($searchTerm) {
                    return $er->createQueryBuilder('u')
                        ->where('u.username LIKE :searchTerm')
                        ->setParameter('searchTerm', '%'.$searchTerm.'%')
                        ->orderBy('u.username', 'ASC');
                },
                'choice_label' => 'username',
                'required' => false,
            ])
