date fields restriction

find out what to change.

For those who are interested.

You have to uncomment this part in custom_buddypresse/bp-functions.php:

if (! function_exists('bpfr_datebox_year_ranges')):
/**
* Filter year field only to allow minimum 18 year old members
*/
function custom_bp_datebox($html, $type, $day, $month, $year, $field_id, $date) {
$current_year = date("Y");
$allowed_year = $current_year - 18;
if($type == 'year'){

for ( $i = $allowed_year; $i >= 1920; $i-- ) {
$html .= '<option value="' . $i .'"' . selected( $year, $i, false ) . '>' . $i . '</option>';
}
}
return $html;
}
endif;
add_filter( 'bp_get_the_profile_field_datebox', 'custom_bp_datebox',10,7);
