Chris@76: /*	This file is mainly concerned with minor tasks relating to boards, such as
Chris@76: 	marking them read, collapsing categories, or quick moderation.  It defines
Chris@76: 	the following list of functions:
Chris@76: 
Chris@76: 	void markBoardsRead(array boards)
Chris@76: 		// !!!
Chris@76: 
Chris@76: 	void MarkRead()
Chris@76: 		// !!!
Chris@76: 
Chris@76: 	int getMsgMemberID(int id_msg)
Chris@76: 		// !!!
Chris@76: 
Chris@76: 	void modifyBoard(int board_id, array boardOptions)
Chris@76: 		- general function to modify the settings and position of a board.
Chris@76: 		- used by ManageBoards.php to change the settings of a board.
Chris@76: 
Chris@76: 	int createBoard(array boardOptions)
Chris@76: 		- general function to create a new board and set its position.
Chris@76: 		- allows (almost) the same options as the modifyBoard() function.
Chris@76: 		- with the option inherit_permissions set, the parent board permissions
Chris@76: 		  will be inherited.
Chris@76: 		- returns the ID of the newly created board.
Chris@76: 
Chris@76: 	void deleteBoards(array boards_to_remove, moveChildrenTo = null)
Chris@76: 		- general function to delete one or more boards.
Chris@76: 		- allows to move the children of the board before deleting it
Chris@76: 		- if moveChildrenTo is set to null, the child boards will be deleted.
Chris@76: 		- deletes all topics that are on the given boards.
Chris@76: 		- deletes all information that's associated with the given boards.
Chris@76: 		- updates the statistics to reflect the new situation.
Chris@76: 
Chris@76: 	void reorderBoards()
Chris@76: 		- updates the database to put all boards in the right order.
Chris@76: 		- sorts the records of the boards table.
Chris@76: 		- used by modifyBoard(), deleteBoards(), modifyCategory(), and
Chris@76: 		  deleteCategories() functions.
Chris@76: 
Chris@76: 	void fixChildren(int parent, int newLevel, int newParent)
Chris@76: 		- recursively updates the children of parent's child_level and
Chris@76: 		  id_parent to newLevel and newParent.
Chris@76: 		- used when a board is deleted or moved, to affect its children.
Chris@76: 
Chris@76: 	bool isChildOf(int child, int parent)
Chris@76: 		- determines if child is a child of parent.
Chris@76: 		- recurses down the tree until there are no more parents.
Chris@76: 		- returns true if child is a child of parent.
Chris@76: 
Chris@76: 	void getBoardTree()
Chris@76: 		- load information regarding the boards and categories.
Chris@76: 		- the information retrieved is stored in globals:
Chris@76: 			- $boards		properties of each board.
Chris@76: 			- $boardList	a list of boards grouped by category ID.
Chris@76: 			- $cat_tree		properties of each category.
Chris@76: 
Chris@76: 	void recursiveBoards()
Chris@76: 		- function used by getBoardTree to recursively get a list of boards.
Chris@76: 
Chris@76: 	bool isChildOf(int child, int parent)
Chris@76: 		- determine if a certain board id is a child of another board.
Chris@76: 		- the parent might be several levels higher than the child.
