I have something like this:
form = FORM('Emails:', BR(),
INPUT(_name='email',
requires=IS_NULL_OR(IS_EMAIL())), BR(),
INPUT(_name='email',
requires=IS_NULL_OR(IS_EMAIL())), BR(),
INPUT(_name='email',
requires=IS_NULL_OR(IS_EMAIL())), BR(),
INPUT(_name='email',
requires=IS_NULL_OR(IS_EMAIL())), BR(),
INPUT(_name='email',
requires=IS_NULL_OR(IS_EMAIL())), BR(),
'Message:', BR(),
TEXTAREA(_name='message'), BR(),
INPUT(_type='submit', _value='Invite'))
However, it seems to crash if I have multiple elements named 'email'.
It works fine if I name them email1, email2, etc. This is the error:
