Disabling Validation when Submitting Forms¶ Contributed by

Thomas Calvet

in #33609. The formnovalidate HTML attribute (defined only for image and input[type=submit] elements) allows to disable client-side validation when submitting a form. In Symfony 4.4, submit buttons ( SubmitType ) define a new validate boolean option to enable/disable this validation: 1 2 3 4 5 6 7 use Symfony\Component\Form\Extension\Core\Type\SubmitType ; // ... $builder -> add ( 'save' , SubmitType :: class ); $builder -> add ( 'save-as-draft' , SubmitType :: class , [ 'validate' => false , ]);

Added Support for Alpha-3 Codes¶ Contributed by

in #33791. The CountryType form field uses Alpha-2 codes by default to refer to each country (e.g. bw = Botswana, sg = Singapore, etc.) In Symfony 4.4, we added a new alpha3 option to it so you can use ISO 3166-1 alpha-3 codes too (e.g. bwa = Botswana, sgp = Singapore): 1 2 3 4 5 6 use Symfony\Component\Form\Extension\Core\Type\CountryType ; // ... $builder -> add ( 'country' , CountryType :: class , [ 'alpha3' => true , ]); Related to this, in the Pull Request #32988, Terje Bråten added support for Alpha-3 codes in the Intl component: 1 2 3 4 5 6 7 8 9 10 use Symfony\Component\Intl\Languages ; use Symfony\Component\Intl\Countries ; $languages = Languages :: getAlpha3Names (); $isValidLanguage = Languages :: alpha3CodeExists ( $alpha3Code ); $alpha3Code = Languages :: getAlpha3Code ( $alpha2Code ); $countries = Countries :: getAlpha3Names (); $isValidCountry = Countries :: alpha3CodeExists ( $alpha3Code ); $alpha3Code = Countries :: getAlpha3Code ( $alpha2Code );

Show Preferred Choices Twice¶ Contributed by Sébastien Alfaiate and Christian Flothmann in #32658. The preferred_choices option of the ChoiceType form field allows to display some choices at the top of the list (e.g. to display first the most popular shipping countries in your store). Although this option is handy for most users, others are confused because the preferred choices are no longer displayed in the full list of choices. That's why starting from Symfony 4.4, preferred choices are displayed twice: at the top of the choice list and at their original location if they weren't preferred.

Automatic Accept Attribute¶ Contributed by

Rémy Lescallier

in #32587. In Symfony 4.4, when you define the mimeTypes option in a File constraint applied to a FileType form field, the value of the mimeTypes option is also used in the accept attribute of the related <input type="file"/> HTML element. This behavior is applied only when using form type guessing and when the field doesn't define its own accept value.
