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