Corrado Prever on "[Plugin: Contact Form 7] validation issue in custom field and custom shortcode"

Thanks for the answer... as you can see in my code I have already inserted the lines.

add_filter('wpcf7_custom_date',  'custom_date_filter', 10, 2);
add_filter('wpcf7_custom_date*', 'custom_date_filter', 10, 2);

why is not working?
