This is happening in functions.php to fire up in members_loop:
Even though the Date of Birth is a private field I still need to pull it so I can calculate and display the user’s age. The below code works fine when I’m logged in as Admin but returns 0 when I’m logged in as a regular user which made me realize it’s probably because it’s set to private.
$dod = bp_get_member_profile_data( 'field=Date of birth' )

How do I get the field value straight from wp_bp_xprofile_fields?
The below isn’t working. I’m assuming it’s terribly wrong. I think I need to include in the db query the userID because it only pulls one value no matter who the user is but how do I get the displayed user’s ID (if that’s the case to begin with)? I managed to get this to work when viewing one’s profile page but I can’t seem to do it in members_loop.

//Add fields in the member directory results
function add_info_to_members_loop() {
//$dateOfBirth = bp_get_member_profile_data( 'field=Date of birth' );//This isn't working

global $wpdb; 
$dateOfBirth = array();
$dateOfBirth = $wpdb->get_col("SELECT value FROM {$wpdb->prefix}bp_xprofile_data WHERE field_id = 2");
$dob = $dateOfBirth[0];

/*This will work when I finally get the date of birth
$today = date("Y-m-d");
$diff = date_diff(date_create($dob), date_create($today));
$state = bp_get_member_profile_data( 'field=State' );
echo 'Age '.$diff->format('%y')  . ' - In ' . $state;
*/
}
add_action( 'bp_directory_members_item', 'add_info_to_members_loop' );

Thank in advance.
