How to set default value for form field in Symfony2?

Question

Is there an easy way to set a default value for text form field?

Answer 1

If you need to set default value and your form relates to the entity, then you should use following approach:

// buildForm() method
public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder
    ...
    ->add(
        'myField',
        'text',
        array(
            'data' => isset($options['data']) ? $options['data']->getMyField() : 'my default value'
        )
    );
}

Otherwise, myField always will be set to default value, instead of getting value from entity.
