To convert a smallint field to a boolean field in a Symfony form, you can use a data transformer. Below is an example of how you can achieve this:

  1. Create a data transformer class:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
18
// src/Form/DataTransformer/SmallIntToBooleanTransformer.php

namespace AppFormDataTransformer;

use SymfonyComponentFormDataTransformerInterface;

class SmallIntToBooleanTransformer implements DataTransformerInterface
{
    public function transform($value)
    {
        return (bool) $value;
    }

    public function reverseTransform($value)
    {
        return $value ? 1 : 0;
    }
}


  1. Register the data transformer as a service in the Symfony services.yaml file:
1
2
3
services:
    AppFormDataTransformerSmallIntToBooleanTransformer:
        tags: ['form.type']


  1. Apply the data transformer to the smallint field in your form type:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
use AppFormDataTransformerSmallIntToBooleanTransformer;

// Inside your form type class
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('is_active', CheckboxType::class, [
        'required' => false,
    ]);

    $builder->get('is_active')->addModelTransformer(new SmallIntToBooleanTransformer());
}


This will allow you to convert the smallint value to a boolean value in your form.
