Multiples form request Symfony 4

Question

I want to build form to perform multiples request. Here is an example of what i want to do

In this case SQL request should be something like this :

SELECT * FROM DB WHERE city = city1 or city = city2 or pet = pet2 or pet = pet3 or food = food1

I tried to do it with symfony with no success because "symfony except string not array"

   class CoreSearchType extends AbstractType
    {
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('city' , ChoiceType::class, [
            'choices' =>array('France' => $this->getChoicesCities()),
                'label' => false,'required' => true,'placeholder'=>'Choose','multiple' => true])

But i dont know what how to do it. If someone can help me finding the way to do it ... Please Notice that i use symfony 4

edit : I want to be able to choose two cities (or more), for exemple : city1 and city2 (all the city1 sample + the city2 sample, and not a variable type-hinted city1 and city2)

for exemple if : city1 = paris, tokyo, rio city2= amiens, madrid, london

the answer of the request will be : paris,tokyo,rio,amiens,madrid,london

Thanks !

From what I can see in your question you want a form which consists of three choice types. Here is an example on how this could look like.

class CoreSearchType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options) 
    {
        $builder
            ->add('city', ChoiceType::class, [
                'choices' => [
                    'city 1' => 'city1',
                    'city 2' => 'city2',
                    'city 3' => 'city3',
                ],
                'label' => false,
                'placeholder' => 'Choose',
                'multiple' => true,
            ])
            ->add('pet', ChoiceType::class, [
                'choices' => [
                    'pet 1' => 'pet1',
                    'pet 2' => 'pet2',
                    'pet 3' => 'pet3',
                ],
                'label' => false,
                'placeholder' => 'Choose',
                'multiple' => true,
            ])
            ->add('city', ChoiceType::class, [
                'choices' => [
                    'food 1' => 'food1',
                    'food 2' => 'food2',
                    'food 3' => 'food3',
                ],
                'label' => false,
                'placeholder' => 'Choose',
                'multiple' => true,
            ])
        ;
    }
}

Please check the part regarding the choices option in the symfony docs here: https://symfony.com/doc/current/reference/forms/types/choice.html#choices

The choices option is an array, where the array key is the item's label and the array value is the item's value

I think your error might come from this line:

'choices' => array('France' => $this->getChoicesCities())

It might work if you change it to

'choices' => array($this->getChoicesCities())
