Description
Steps to reproduce:¶
- Create a new form in the backend wizard.
- Create a radio button element (eg Number of children) in this form with options: 0, 1, 2, 3 (same label & value).
Current result:¶
In the frontend the first option has an empty string as the label.
Expected result:¶
The first option has '0' as the label.
Problem:¶
There are "empty variable" conditions in TYPO3\CMS\Form\Service\TranslationService->translateFormElementValue() on lines 364 & 368. This will be true if the string is empty or equal to '0' (https://www.php.net/manual/en/function.empty.php).
Solution:¶
Change conditions to:
(empty($defaultValue) && $defaultValue !== '0')
