How to make a search query for Max and Min in Symfony4?

Question

I have two fields for Searching, that is, Min and Maximum.

Here, I want to display all the products which are between min and maximum.

Help me I'm new to Symfony.

Answer 1

There are two options :

1. Simple.

   • create ordinary html form in template (that you've already done):

<form>
    <input name="min" value="{{ min }}">
    <input name="max" value="{{ max }}">
    <input type="submit" value="Search">
</form>

• in your controller :

public function listPhones(Request $request, EntityManagerInterface $em) 
{
    // get submitted values
    $min = $request->get('min');
    $min = $request->get('min');

    $phones = $em->getRepository(Phone::class)->search($min, $max);

    return ['phones' => $phones, 'min' => $min, 'max' => $max]
}

• in your entity repository:

class PhoneRepository extends EntityRepository 
{
    public function search($min = null, $max = null) 
    {
        $qb = $this->createQueryBuilder('p');
        if (!is_null($min)) {
            $qb->andWhere('p.price >= :min')
               ->setParameter('min', $min);
        }
        if (!is_null($max)) {
            $qb->andWhere('p.price <= :max')
               ->setParameter('max', $max);
        }

        return $qb->getQuery()->getResult();
    }
}

2. Symfony way, using Symfony Forms. It is a way more complex, I will explain on demand.
