BuddyPress.org

Hello Guys,

I am creating a post subscription. When any user subscribe to any post I want to send them notifications about comments and post activities. I am adding custom notifications to buddypress. Notifications are adding but in frontend the title of notification is not showing. I checked many forums but did not find any solution.

Below is my code:

public function __construct() {
      
      add_filter( 'bp_notifications_get_registered_components', array($this,'custom_filter_notifications_get_registered_components'),20 );
      add_filter( 'bp_notifications_get_notifications_for_user', array($this,'custom_format_buddypress_notifications'), 10, 7 );
      add_action( 'wp_insert_comment', array($this,'bp_custom_add_notification'), 99, 2 );
   }

For custom component

public function custom_filter_notifications_get_registered_components( $component_names = array() ) {
 
       // Force $component_names to be an array
       if ( ! is_array( $component_names ) ) {
           $component_names = array();
       }
    
       // Add 'custom' component to registered components array
       array_push( $component_names, 'custom' );
    
       // Return component's with 'custom' appended
       return $component_names;
   }

For notification formatting

public function custom_format_buddypress_notifications( $content, $item_id, $secondary_item_id, $total_items, $format = 'string', $action, $component ) {
     	   
         if ( 'custom_action' === $action ){
           $comment = get_comment( $item_id );
        
           $custom_title = $comment->comment_author . ' commented on the post ' . get_the_title( $comment->comment_post_ID );
           $custom_link  = get_comment_link( $comment );
           $custom_text = $comment->comment_author . ' commented on your post ' . get_the_title( $comment->comment_post_ID );
    
           // WordPress Toolbar
           if ( 'string' === $format ) {
               $data_to_return = apply_filters_ref_array( 'custom_filter', '<a href="' . esc_url( $custom_link ) . '" title="' . esc_attr( $custom_title ) . '">' . esc_html( $custom_text ) . '</a>', $custom_text, $custom_link );
               
    
           // Deprecated BuddyBar
           } else {
               $data_to_return = apply_filters_ref_array( 'custom_filter', array(
                   'text' => $custom_text,
                   'link' => $custom_link
               ), $custom_link, (int) $total_items, $item_id, $secondary_item_id );
           }
           
         return $data_to_return;     
      } else{
         return $action;
      } 
   }

For adding notification

public function bp_custom_add_notification( $comment_id, $comment_object ) {
 
      $subscribed_user =  get_post_meta( $comment_object->comment_post_ID , 'subscribed_user',true ); 
      
      if(!empty($subscribed_user) && is_array($subscribed_user)){
         for ($i=0; $i < count($subscribed_user); $i++) { 
      		 if ( bp_is_active( 'notifications' ) ) {
                  bp_notifications_add_notification( array(
                     'user_id'           => $subscribed_user[$i],
                     'item_id'           => $comment_id,
                     'component_name'    => 'custom',
                     'component_action'  => 'custom_action',
                     'date_notified'     => bp_core_current_time(),
                     'is_new'            => 1,
                   ) );
      		 }
         }
      }   
   }

Please suggest best possible way to fix this issue.

Thank You
