Labels and languages

The widget

Cap translates its own labels. The bundle passes the request locale as data-cap-lang, so the widget speaks the language of the page. Override it per field:

$builder->add('cap', CapType::class, ['locale' => 'de']);

Or replace any label with the i18n option, keyed by the suffix of Cap’s data-cap-i18n-* attributes:

$builder->add('cap', CapType::class, [
    'i18n' => [
        'initial-state' => $this->translator->trans('cap.verify'),
        'solved-label' => $this->translator->trans('cap.solved'),
    ],
]);

The keys are initial-state, verifying-label, solved-label, error-label, troubleshooting-label, wasm-disabled, verify-aria-label, verifying-aria-label, verified-aria-label, error-aria-label and required-label (the browser message of an unticked required widget).

Validation messages

The two messages of the Cap constraint are translated in the validators domain, in English, French, German, Spanish, Italian, Dutch and Portuguese. Override them in your own translations/validators.<locale>.xlf:

translations/validators.fr.yaml

'Please verify you are human.': 'Cochez la case « Je ne suis pas un robot ».'
'The human verification failed, please try again.': 'Vérification impossible, réessayez.'

Or pass other messages to the constraint:

use Silarhi\CapBundle\Validator\Cap;

$builder->add('cap', CapType::class, [
    'constraints' => [new Cap(message: 'cap.failed', missingMessage: 'cap.missing')],
]);
