Trying to insert buddypress avatar url into postgres table when user upload new avatar.
Function bp_loggedin_user_avatar( ‘html=false’ ) gives proper URL but it just echoes it to screen.Not able to assigned value to variable $user_avatar_url and include it into query.
Is there way to have url properly inserted into sql query?

if ( ! bp_core_avatar_handle_crop( $args ) ) {
			bp_core_add_message( __( 'There was a problem cropping your avatar.', 'buddypress' ), 'error' );
		} else {
			bp_core_add_message( __( 'Your new avatar was uploaded successfully.', 'buddypress' ) );
			do_action( 'xprofile_avatar_uploaded' );
                        // save avatar to postgres
                         $logged_email= bp_core_get_user_email(get_current_user_id());
                         
                         $user_avatar_url= bp_loggedin_user_avatar( 'html=false' );
                        
                         
                         
                         $query = "UPDATE table_name SET avatar = '$user_avatar_url'  WHERE user_email = '$logged_email'";
echo $query;

pg_exec($query);

		}
	}
