can_comment_on_post	(	$observer_xchan,
		$item
	)

can_comment_on_post($observer_xchan,$item);

This function examines the comment_policy attached to an item and decides if the current observer has sufficient privileges to comment. This will normally be called on a remote site where perm_is_allowed() will not be suitable because the post owner does not have a local channel_id. Generally we should look at the item - in particular the author['book_flags'] and see if ABOOK_FLAG_SELF is set. If it is, you should be able to use perm_is_allowed( ... 'post_comments'), and if it isn't you need to call can_comment_on_post()

check_item_source	(	$uid,

check_item_source($uid,$item)

Parameters

$uid
$item	Checks to see if this item owner is referenced as a source for this channel and if the post matches the rules for inclusion in this channel. Returns true if we should create a second delivery chain and false if none of the rules apply, or if the item is private.

consume_feed	(		$xml,

			$pass = `0`
	)

consume_feed - process atom feed and update anything/everything we might need to update

$xml = the (atom) feed to consume - RSS isn't as fully supported but may work for simple feeds.

$importer = the contact_record (joined to user_record) of the local user who owns this relationship. It is this person's stuff that is going to be updated. $contact = the person who is sending us stuff. If not set, we MAY be processing a "follow" activity from an external network and MAY create an appropriate contact record. Otherwise, we MUST have a contact record. $hub = should we find a hub declation in the feed, pass it back to our calling process, who might (or might not) try and subscribe to it. $datedir sorts in reverse order $pass - by default ($pass = 0) we cannot guarantee that a parent item has been imported prior to its children being seen in the stream unless we are certain of how the feed is arranged/ordered. With $pass = 1, we only pull parent items out of the stream. With $pass = 2, we only pull children (comments/likes).

So running this twice, first with pass 1 and then with pass 2 will do the right thing regardless of feed ordering. This won't be adequate in a fully-threaded model where comments can have sub-threads. That would require some massive sorting to get all the feed items into a mostly linear ordering, and might still require recursion.

post an activity

Parameters

array $arr In its simplest form one needs only to set $arr['body'] to post a note to the logged in channel's wall. Much more complex activities can be created. Permissions are checked. No filtering, tag expansion or other processing is performed.

Returns: array 'success' => true or false 'activity' => the resulting activity if successful

red_zrl_callback preg_match function when fixing 'naked' links in mod item.php Check if we've got a hubloc for the site and use a zrl if we do, a url if we don't. Remove any existing zid= param which may have been pasted by mistake - and will have the author's credentials. zid's are dynamic and can't really be passed around like that.
