function revisioning_revisionapi in Revisioning 6.4

Same name and namespace in other branches

1. 8 revisioning_api.inc \revisioning_revisionapi()
2. 6.3 revisioning_api.inc \revisioning_revisionapi()
3. 7 revisioning_api.inc \revisioning_revisionapi()

Implementation of hook_revisionapi().

Act on various revision events.

@TODO: Add more operations if needed.

Parameters

$op: Operation

$node: Node of current operation (loaded with vid of the operation).

"Pre" operations can be useful to get values before they are lost or changed, for example, to save a backup of revision before it's deleted. Also, for "pre" operations vetoing mechanics could be implemented, so it would be possible to veto an operation via hook_revisionapi(). For example, when the hook is returning FALSE, operation will be vetoed.
