Have setup Additional Fields in the signup_form.inc and all works with the Signup Form. However, I cannot see the content of the field in the signup_user_vbo_admin_list view.
One additional field in the signup_form.inc:
$days_options = array(
'Working Saturday' => t('Saturday'),
'Working Sunday' => t('Sunday'),
'#type' => 'checkboxes',
'#title' => t('What days can you work'),
'#options' => $days_options,
'#description' => t('Please select the days with you can work. If not working a full day, please indicate the day and time on the Additional Information line.'),
Produces in the view:
How can I see what is in the dayswork and not 'Array'?
