Forms

TypedUrlType is one text field, to and from a TypedUrl: the kind of the address is detected among the types it accepts.

$builder->add('social', TypedUrlType::class, ['types' => [KnownUrlType::Facebook, KnownUrlType::Instagram]]);

• It extends Symfony's UrlType, with https as the default protocol: instagram.com/shop is read as https://instagram.com/shop.
• An empty field is null; an address of no accepted kind makes the field invalid with This address is not one of the accepted kinds.
