无法加载类型“App\Form\RepeatedType”：类不存在

Question

I upgrade from synfony 4 to 5. Then i try to test my registration page and get this: Could not load type "App\Form\RepeatedType": class does not exist.

What i have try:

• composer install --no-dev --optimize-autoloader (i found this online)

The result:

Script @auto-scripts was called via post-install-cmd 

WEIRD because others forms worked just before (and now they are broken saying: Attempted to load class "MakerBundle" from namespace "Symfony\Bundle\MakerBundle". Did you forget a "use" statement for another namespace? )

• composer require symfony/maker-bundle --dev Now it's working again except for the registration page ("App\Form\RepeatedType": class does not exist.).

It's worth notting that my autocomplet find Symfony\Component\Form\Extension\Core\Type\RepeatedType in the folder. And sometimes when i clear cache, it crash when optimizing.

Thanks for reading.

Answer 1

In symfony 5 the use statement for RepeatedType is use Symfony\Component\Form\Extension\Core\Type\RepeatedType;

And to use for let's say a password fiel you would type something like:

$builder
->add('password', RepeatedType::class, [
    'type' => PasswordType::class,
    'required' => false,
    'mapped' => false,
    'first_options' => ['label' => 'New password'],
    'second_options' => ['label' => 'Repeat password'],
]);
