I would like to visualize where data is passed, from its start point to its end point. Is there a way to use php log to create list of where data has been passed?
If NO - Maybe you can offer me some advice.
The code below is for an activity feed. Data posted is passed into one function - placed into an array, and passed to the function below. From there the data is transferred to this class and I would like to understand what happens to it from there.
function bp_activity_add( $args = '' ) {
$defaults = array(
'id' => false, // Pass an existing activity ID to update an existing entry.
'action' => '', // The activity action - e.g. "Jon Doe posted an update"
'content' => '', // Optional: The content of the activity item e.g. "BuddyPress is awesome guys!"
'component' => false, // The name/ID of the component e.g. groups, profile, mycomponent
'type' => false, // The activity type e.g. activity_update, profile_updated
'primary_link' => '', // Optional: The primary URL for this item in RSS feeds (defaults to activity permalink)
'user_id' => bp_loggedin_user_id(), // Optional: The user to record the activity for, can be false if this activity is not for a user.
'item_id' => false, // Optional: The ID of the specific item being recorded, e.g. a blog_id
'secondary_item_id' => false, // Optional: A second ID used to further filter e.g. a comment_id
'recorded_time' => bp_core_current_time(), // The GMT time that this activity was recorded
'hide_sitewide' => false, // Should this be hidden on the sitewide activity stream?
'is_spam' => false, // Is this activity item to be marked as spam?
);
$params = wp_parse_args( $args, $defaults );
extract( $params, EXTR_SKIP );
// Make sure we are backwards compatible
if ( empty( $component ) && !empty( $component_name ) )
$component = $component_name;
if ( empty( $type ) && !empty( $component_action ) )
$type = $component_action;
// Setup activity to be added
$activity = new BP_Activity_Activity( $id );
$activity->user_id = $user_id;
$activity->component = $component;
$activity->type = $type;
$activity->action = $action;
$activity->content = $content;
$activity->primary_link = $primary_link;
$activity->item_id = $item_id;
$activity->secondary_item_id = $secondary_item_id;
$activity->date_recorded = $recorded_time;
$activity->hide_sitewide = $hide_sitewide;
$activity->is_spam = $is_spam;
if ( !$activity->save() )
return false;
// If this is an activity comment, rebuild the tree
if ( 'activity_comment' == $activity->type )
BP_Activity_Activity::rebuild_activity_comment_tree( $activity->item_id );
wp_cache_delete( 'bp_activity_sitewide_front', 'bp' );
do_action( 'bp_activity_add', $params );
return $activity->id;
}
