BuddyPress.org

My Scenario:

I only have one profile group, and two member types.

Each of them has some shared required fields, which I have set as required, but I would like some additional fields to be made required for each member type.

IE

Shared Member Fields: Name, Age

Separate for Member Type A: XProfile Field A

Separate for Member Type B: Xprofile Field B

Currently, I am showing this fields conditionally using the Conditional Profile Fields for BuddyPress plugin as they select a Member Type, and at this stage I’d consider them mandatory, although I can’t have both XProfile Field A and B both marked as required in BuddyPress.

I’ve looked up a couple of solutions, and mine is mainly based on the following: buddypress bp_core_add_message() doesn’t fire why?

For a required field, it shows the error message, but not so for the custom error message I want to display, could someone give me a pointer as to why?

 //Validate and force values for items that are NOT required
function validate_required_unshared_fields($data) {
        global $bp;
//check for member type
$member_type_field_id = xprofile_get_field_id_from_name('Member Type');
$member_type = $_POST['field_'.$member_type_field_id];
switch($member_type){
case "babysitterornanny":
$cost_per_hour_field_id = xprofile_get_field_id_from_name('Cost Per Hour');
$cost_per_hour = $_POST['field_'.$cost_per_hour_field_id];

if ($cost_per_hour ==''){

bp_core_add_message( __( 'You need to fill out your Cost Per Hour.', 'buddypress' ), 'error' );
          wp_redirect( $bp->loggedin_user->domain . 'profile/edit/group/1/' );

       exit();
}

}

return $data;
}

add_action( 'xprofile_data_before_save', 'validate_required_unshared_fields');

I’ve changed to a default Twenty12 theme, still doesn’t display, what is causing it not to display??
