Checked but not added to list

Hi Kasper,

In your class MailPoet_CF7_Submit_Form at line 64 (function add_email_list) my form data ($form_data) for mailpoetsignup is 0 (checked) or “” (not checked). Because of the ‘ && !empty($form_data[$field_names[‘mailpoetsignup’]]) ‘ in the up following if statement its not adding my signup to a list. Is it possible to change your if or is the class ‘WPCF7_Submission’ causing the problem?

In my cf7 form:
[mailpoetsignup mailpoetsignup-3005 list:5 default:on class:checkbox_nieuwsbrief "Stuur mij af en toe een nieuwsbrief via email"]

Thanks for your help.
Martin
