[rickyviz]

i create custom radio button for repeatable element, this for make default contact number,
but i cant get old value on edit, (using for showing checked radio element)

i am using this to get old value , but it can't
$current_value = old(square_brackets_to_dots($field['value'])) ?? $field['value'] ?? $field['default'] ?? ''; this blade custom radio button

in controller

when edit and adding new repeatable elements,i got default value on,the default value should be false, like when on create

Hello @rickyviz

Please have a look in our fields and update your code. You should be using our helper old_empty_or_null() with the coalescing chain to properly get field values.
