thanks @danbp ,

I just made test, but still the same. I put the first function (celbirthday_notifier_setup_globals ()) in bp-custom.php within plugins folder and still the same, the function does nothing, unless you called: celbirthday_notifier_setup_globals ();
I believe that I am missing some basics to understand this.

[chicho1969]

okay, This is almost done, but is really rare, not everything works as it should.
First of all, this is not a pluggin, I am writing all these code in bp-functions.php in my bududdypress folder within my theme folder. (this may be my problem).
Step by step:
1st Problem setup globals is not working as it espected:

define( 'BP_NOTIFIER_CELBIRTHDAY_SLUG', 'celbirthday_notifier' );
function celbirthday_notifier_setup_globals () {
	global $bp, $wpdb;
	$bp = buddypress();
	
	$bp->celbirthday_notifier = new stdClass();
	$bp->celbirthday_notifier->id = 'celbirthday_notifier'; //I asume others are not going to use this is
	$bp->celbirthday_notifier->slug = BP_NOTIFIER_CELBIRTHDAY_SLUG;
	$bp->celbirthday_notifier->notification_callback = 'celbirthday_notifier_format_notifications'; //show the notification
	
	$bp->active_components[$bp->celbirthday_notifier->id] = $bp->celbirthday_notifier->id;

	do_action( 'bp_setup_globals' );
}

This function is not doing nothing unless I call it directly:
celbirthday_notifier_setup_globals ();
I Know this is not the proper way, but it is the only way I found to make it run.
Does anyone know why it does not work properly?

Continue with the notification:

//Format notifications
function celbirthday_notifier_format_notifications( $action, $item_id, $secondary_item_id, $total_items, $format = 'string' ) {
 if ( 'new_birthday' === $action ) {
	if ( (int) $total_items > 1 ) {
	      
	    if ( 'string' === $format ) {
			$famoso_name =  get_the_title( $secondary_item_id );
			return apply_filters( 'celebrities_multiple_verifications_notification','Say Happybirthday to '.$famoso_name);	  
		  }
      } else {	 
      if ( 'string' === $format ) {  //falta definir $famoso_link y mas 
	   $famoso_name =  get_the_title( $secondary_item_id );
	  	return apply_filters( 'celebrities_single_verifications_notification','Say Happybirthday to '.$famoso_name);
         // $return = apply_filters( $filter, '<a href="' . esc_url( $famoso_link ) . '" title="birthday anounce">' . esc_html( $text ) . '</a>', (int) $total_items, $text, $famoso_link );
		// $message = apply_filters( 'bp_activity_at_message_notification_message', $message, $poster_name, $content, $message_link, $settings_link );

	} } }
 do_action( 'celbirthday_notifier_format_notifications', $action, $item_id, $secondary_item_id, $total_items ); 
return false; }

ok, this format function is working right, although I have to do some more work. After it, I have two more functions (mark and delete notifications) wich are also working fine.

//mark notification
function celebrities_mark_screen_notifications() {
	global $bp;
	
	bp_notifications_mark_notifications_by_item_id( $bp->loggedin_user->id, $bp->celbirthday_notifier->id, 'new_birthday', $secondary_item_id = false, $is_new='0');
}
add_action( 'bp_notifications_screen', 'celebrities_mark_screen_notifications' ); 

and…

function celbirthday_notifier_remove_screen_notifications() {
	global $bp;
	
	bp_core_delete_notifications_for_user_by_type( $bp->loggedin_user->id, $bp->profile->slug, 'new_birthday' );
}
add_action( 'bp_notifications_screen', 'celbirthday_notifier_remove_screen_notifications' );
add_action( 'xprofile_screen_display_profile', 'celbirthday_notifier_remove_screen_notifications' );

As I say, this works fine, but a I am not sure if I need the second “add_action” (xprofile screen).
And finally, to add notification I use this code (which is not working):

//Adding notification
function buddypress_celebrities_add_notification() 
{    
if ( bp_is_active( 'notifications' ) )
 {  

	$fecha_act = date("Y-m-d");
	$res_birth = $wpdb->get_results( "SELECT wp_best_favs.user_id, wp_postmeta.post_id
					FROM wp_best_favs
					LEFT JOIN wp_postmeta ON ( wp_postmeta.post_id = wp_best_favs.celeb_ID ) 
					WHERE (
					wp_postmeta.meta_key =  'fecha_na')
					AND (DAY(  <code>wp_postmeta</code>.<code>meta_value</code> ) = DAY(  '$fecha_act' ))					
					AND (MONTH(  <code>wp_postmeta</code>.<code>meta_value</code> ) = MONTH(  '$fecha_act' ))
					");
			$res_birth = array_filter($res_birth);  
			$matriz = objectToArray($res_birth);  //I use this function to convert objet array to simple array
			if(count($matriz)==0) 
			{ 
				// está vacío 
			}  else { 
				global $wpdb;
				$bp = buddypress();
				$current_time = bp_core_current_time();
				foreach ($matriz as $v1) {
					
					$famoso_id = $v1[post_id];
					$receiver_user_id = $v1[user_id];
						
				$args = array(
					'user_id'           => $receiver_user_id,
					'item_id'           => $famoso_id,
					'secondary_item_id' => $famoso_id,
					'component_name'    => $bp->celbirthday_notifier->slug,
					'component_action'  => 'new_birthday',
					'date_notified'     => $current_time,
					'is_new'            => 1,
	       				 );
			 bp_notifications_add_notification( $args );
		}
	}
 } 
} 
do_action( 'bp_init', 'buddypress_celebrities_add_notification' ); 

So this is my bigger problem:
Add notifications (function buddypress_celebrities_add_notification()) is not working.
I am pretty sure this is because I am not hooking properly, but I tried so many hooks and none of it did work.
I Know the code is fine because if I comment the two first lines and the two last lines (so I run the code not as a function) the notifications are being added to database.

Anyone can help me, to find a proper hook, or just pointing me in the right direction.
Thanks in advance.

Thank you @danbp , will see, in the main time I keep trying and will update if I make progress.

[chicho1969]

Thanks @danbp ,
I´ll try to explain you:

I have a custom_post_type (celebrities). it real name is “famosos”.
BuddyPressUsers can mark any celebrity as fasvourite.
This part is working fine.
So now, I am trying to send a notification (to users that have marked as favorite certain celebriry) that “today” is that celebrity´s birthday.

For that purpose, I have a SQL query that works fine and gives me an array with budypress user id and the celebritie post id. (this is also working fine)

SO I have to setup a custom notificationa that checks every day that SQL QUery to gets users and celebrities ids to notify user about today´s birthday (of their favourite celebrities)

and this is what I did at first:

define( 'BP_ACTIVITY_CELBIRTHDAY_SLUG', 'celbirthday_notifier' );
function celbirthday_notifier_setup_globals () {
	
	$bp = buddypress();
	
	$bp->celbirthday_notifier = new stdClass();
	$bp->celbirthday_notifier->id = 'celbirthday_notifier'; //I asume others are not going to use this is
	$bp->celbirthday_notifier->slug = BP_ACTIVITY_CELBIRTHDAY_SLUG;
	$bp->celbirthday_notifier->notification_callback = 'celbirthday_notifier_format_notifications'; //show the notification
	
	$bp->active_components[$bp->celbirthday_notifier->id] = $bp->celbirthday_notifier->id;

	do_action( 'celbirthday_notifier_setup_globals' );
}

add_action( 'bp_setup_globals', 'celbirthday_notifier_setup_globals' );

and then try to format the notification:

function celbirthday_notifier_format_notifications( $action, $item_id, $secondary_item_id, $total_items, $format = 'string' ) {
 if ( 'new_birthday' === $action ) {
                $famoso_name =  get_the_title( $secondary_item_id );
		$subject = 'Celebrity birthday';
		$message = 'Say happy birthday to $famoso_name';
		$content = 'Tody is $famoso_name birthday .....somethin else ';
		if ( (int) $total_items > 1 ) {
          $text = sprintf( __( 'You have %d celebrities birthday', 'bbpress' ), (int) $total_items );
          $filter = 'bp_activity_at_message_notification_message';
      } else {
          if ( !empty( $secondary_item_id ) ) {
              //nada
          } else {
              $text = sprintf( __( 'You have %d new birthday of %s', 'bbpress' ), (int) $total_items, $famoso_name );
          }
          $filter = 'bp_activity_at_message_notification_message';
      }
	 }
      if ( 'string' === $format ) {  //falta definir $famoso_link y mas 
          $return = apply_filters( $filter, '<a href="' . esc_url( $famoso_link ) . '" title="birthday anounce">' . esc_html( $text ) . '</a>', (int) $total_items, $text, $famoso_link );
		// $message = apply_filters( 'bp_activity_at_message_notification_message', $message, $poster_name, $content, $message_link, $settings_link );

} } do_action( 'celbirthday_notifier_format_notifications', $action, $item_id, $secondary_item_id, $total_items );

and then add notification this way:

function buddypress_celebrities_add_notification( $fecha_act,  $famoso_name, $receiver_user_id) 
{    if ( bp_is_active( 'notifications' ) ) { 

	$fecha_act = date("Y-m-d");
	$res_birth = $wpdb->get_results( "SELECT wp_best_favs.user_id, wp_postmeta.post_id
					FROM wp_best_favs
					LEFT JOIN wp_postmeta ON ( wp_postmeta.post_id = wp_best_favs.celeb_ID ) 
					WHERE (
					wp_postmeta.meta_key =  'fecha_na')
					AND (DAY(  <code>wp_postmeta</code>.<code>meta_value</code> ) = DAY(  '$fecha_act' ))					AND (MONTH(  <code>wp_postmeta</code>.<code>meta_value</code> ) = MONTH(  '$fecha_act' )							)
									") ;
			$res_birth = array_filter($res_birth);  
			$matriz = objectToArray($res_birth);  //convertimos el array de objetos en array normal para manejarlo mas facil
			$current_time = bp_core_current_time();
			if(count($matriz)==0) { 
				// está vacío 
				}  else { 
					global $wpdb;
					$bp = buddypress();
					$subject = 'Celebrity birthday';
					$message = '1 Say happy birthday to $famoso_name';
					$content = '2 Say happy birthday to $famoso_name';
					foreach ($matriz as $v1) {
					
						$famoso_id = $v1[post_id];
						$famoso_name = get_the_title ($v1[post_id]);
						$receiver_user_id = $v1[user_id];
						
					$args = array(
							'user_id'           => $receiver_user_id,
							'item_id'           => $famoso_id,
							'secondary_item_id' => $famoso_id,
							'component_name'    => $bp->celbirthday_notifier->id,
							'component_action'  => 'new_birthday',
							'date_notified'     => $current_time,
							'is_new'            => 1,
	       					 );
							 
							 bp_notifications_add_notification( $args );
						 
			}	}  }	} add_action( 'new_birthday', 'buddypress_celebrities_add_notification', 10, 1 );

so far this is what I am trying to do, hope you understand.
Thanks in advance.

[chicho1969]

Thanks for reply.

Yes I read those articles (…and much more), but still not understanding, Sorry about it, thus I am asking for help.

I don,t understand what do you mean with use a function name twice:
(// do_action( ‘setup_globals’ ); This is commented) ,

is this a better way to do it?:

function sr_notifications_test_setup_globals () {	
	global $bp, $current_blog;
	$bp->sr_notifications_test = new stdClass();
	$bp->sr_notifications_test->id = 'sr_notifications_test';
	$bp->sr_notifications_test->slug = 'sr_notifications_test';
	$bp->sr_notifications_test->notification_callback = 'sr_format_notifications_test'; 
	$bp->active_components[$bp->sr_notifications_test->id] = $bp->sr_notifications_test->id;
	do_action( 'sr_notifications_test_setup_globals ' );
}
add_action( 'bp_notification_settings', 'sr_notifications_test_setup_globals ' ); 

Anyway, what I understood is that I have to write those 3 functions to make my custom notifications works:
1.- setup_globals
2.- format_notifications (called from set_up_globals, notification_callback)
If Iunderstood you´, the filter I have to use is bp_notifications_get_notifications_for_user
3.- _add_notification

is this the right way?

[chicho1969]

forget it I misunderstood

[chicho1969]

You may try this pluging: BuddyPress Activity Plus, I am pretty sure that it doews what you are looking for. link; https://wordpress.org/plugins/buddypress-activity-plus/

[chicho1969]

Ok, now I am trying this:

//function class

function setup_globals( $args = array() ) {
global $bp;
$sr_notifications_test_slug = 'sr_notifications_test';
parent::setup_globals( array(
'id' => 'sr_notifications_test',
'slug' => $sr_notifications_test_slug,
'notification_callback' => array( $this, 'sr_format_notifications_test' )
) );
/* Register this in the active components array */
$bp->active_components[$sr_notifications_test_slug] = 'sr_notifications_test';
// do_action( 'setup_globals' );
}

//format notofication
function sr_format_notifications_test( $action, $item_id, $secondary_item_id, $total_items, $format = 'string' ) {

switch ( $action ) {
case 'my_test':
$link = get_permalink( $item_id );
$text = 'Test Notification';

$return = apply_filters( $filter, array(
'text' => $text,
'link' => $link
), $link, (int) $total_items, $text, $link, $item_id, $secondary_item_id );
break;
}

do_action( 'sr_format_notifications_test', $action, $item_id, $secondary_item_id, $total_items );
return $return;
}

//Notification added to DB:
bp_notifications_add_notification( array(
'user_id' => $user_id,
'item_id' => $activity->id,
'secondary_item_id' => $activity->user_id,
'component_name' => buddypress()->activity->id,
'component_action' => 'my_test',
'date_notified' => bp_core_current_time(),
'is_new' => 1

) );
print_r ($bp->active_components[$sr_notifications_test_slug]);

and this is the error I have: (still the same)

WordPress database error: [Table 'WP_db_funs.n' doesn't exist]
SELECT * FROM n WHERE component_name IN ('activity') AND component_action IN ('my_test') AND is_new = 1
WordPress database error: [Incorrect table name ”]
INSERT INTO (user_id,item_id,secondary_item_id,component_name,component_action,date_notified,is_new) VALUES (0,0,0,'activity','my_test','2015-08-12 15:57:21′,1)

Please if anybody Knows about this I will apreciate any help 🙁

Table ‘WP_db_funs.n’ doesn’t exist how come?? table n ??
