Display block after some action (saved node) I want to display block after an action. My user will create new content (node). After he save it, the content is shown with a specific block (only once, no further).

I was looking on trigger module, but I do not see this option.

I am using Drupal 6

Thank you for help!
You can use Rules + Rules Bonus Pack for this. The Rules Bonus Pack module has actions for enabling and disabling blocks upon a certain event (e.g. save a node). See this screencast for an explanation.

Note; Rules Bonus Pack is a testing ground for new functionality for the Rules module, so test thoroughly. However, the linked screencast above was published in 2011, so perhaps the code had some test mileage already.
