/* This file handles merging and splitting topics... it does this with:
void SplitTopics()
- splits a topic into two topics.
- delegates to the other functions (based on the URL parameter 'sa').
- loads the SplitTopics template.
- requires the split_any permission.
- is accessed with ?action=splittopics.
void SplitIndex()
- screen shown before the actual split.
- is accessed with ?action=splittopics;sa=index.
- default sub action for ?action=splittopics.
- uses 'ask' sub template of the SplitTopics template.
- redirects to SplitSelectTopics if the message given turns out to be
the first message of a topic.
- shows the user three ways to split the current topic.
void SplitExecute()
- do the actual split.
- is accessed with ?action=splittopics;sa=execute.
- uses the main SplitTopics template.
- supports three ways of splitting:
(1) only one message is split off.
(2) all messages after and including a given message are split off.
(3) select topics to split (redirects to SplitSelectTopics()).
- uses splitTopic function to do the actual splitting.
void SplitSelectTopics()
- allows the user to select the messages to be split.
- is accessed with ?action=splittopics;sa=selectTopics.
- uses 'select' sub template of the SplitTopics template or (for
XMLhttp) the 'split' sub template of the Xml template.
- supports XMLhttp for adding/removing a message to the selection.
- uses a session variable to store the selected topics.
- shows two independent page indexes for both the selected and
not-selected messages (;topic=1.x;start2=y).
void SplitSelectionExecute()
- do the actual split of a selection of topics.
- is accessed with ?action=splittopics;sa=splitSelection.
- uses the main SplitTopics template.
- uses splitTopic function to do the actual splitting.
int splitTopic(int topicID, array messagesToBeSplit, string newSubject)
- general function to split off a topic.
- creates a new topic and moves the messages with the IDs in
array messagesToBeSplit to the new topic.
- the subject of the newly created topic is set to 'newSubject'.
- marks the newly created message as read for the user splitting it.
- updates the statistics to reflect a newly created topic.
- logs the action in the moderation log.
- a notification is sent to all users monitoring this topic.
- returns the topic ID of the new split topic.
void MergeTopics()
- merges two or more topics into one topic.
- delegates to the other functions (based on the URL parameter sa).
- loads the SplitTopics template.
- requires the merge_any permission.
- is accessed with ?action=mergetopics.
void MergeIndex()
- allows to pick a topic to merge the current topic with.
- is accessed with ?action=mergetopics;sa=index
- default sub action for ?action=mergetopics.
- uses 'merge' sub template of the SplitTopics template.
- allows to set a different target board.
void MergeExecute(array topics = request)
- set merge options and do the actual merge of two or more topics.
- the merge options screen:
- shows topics to be merged and allows to set some merge options.
- is accessed by ?action=mergetopics;sa=options.and can also
internally be called by QuickModeration() (Subs-Boards.php).
- uses 'merge_extra_options' sub template of the SplitTopics
template.
- the actual merge:
- is accessed with ?action=mergetopics;sa=execute.
- updates the statistics to reflect the merge.
- logs the action in the moderation log.
- sends a notification is sent to all users monitoring this topic.
- redirects to ?action=mergetopics;sa=done.
void MergeDone()
- shows a 'merge completed' screen.
- is accessed with ?action=mergetopics;sa=done.
- uses 'merge_done' sub template of the SplitTopics template.
