Filtering bp_get_activity_content_body, bp_get_activity_secondary_item_id

    I’m trying to filter the activity content body, but bp_get_activity_secondary_item_id keeps returning 0. What I want is, when users comment on a post with a featured image, for that image to appear appended to the activity body. Here’s what I’m using:

    add_filter( 'bp_get_activity_content_body', 'cshp_add_thumbs_to_activity', 0, 1 );
	function cshp_add_thumbs_to_activity( $bp_activity_filter_kses, $number ){

		$post_id = bp_get_activity_secondary_item_id();

		if( has_post_thumbnail( get_post( $post_id ) ) )
			$attachment = wp_get_attachment_image( $post_id );

		$new_content = $attachment ? $bp_activity_filter_kses . "<br />\n" . $attachment : $bp_activity_filter_kses;

		return $new_content;
	}

    Thanks

    The filter call is:
    apply_filters_ref_array( 'bp_get_activity_content_body', array( $activities_template->activity->content, &$activities_template->activity ) );

    Your function expects 2 parameters. Your add_filter call states there is only one.

    And there is only one – an array.
    Read about that kind of filter https://codex.wordpress.org/Function_Reference/apply_filters_ref_array

    Try something like this:

    function cshp_add_thumbs_to_activity( $array ) { 
     $post_id = $array[1]->secondary_item_id;
    //etc

    $array[0] = // new content

    return $array; 

}
add_filter( 'bp_get_activity_content_body', 'cshp_add_thumbs_to_activity', 15, 1 );
