I've created a demo content contrib module that adds a bunch of book pages. I save the pages one at a time and each time I save, Backdrop creates a status message.
At the end of the installation, I have a page full of installation messages = "Reorder book pages from the book outline."
Can I easily suppress the automatic message in favor of a custom message I output at the end that summarizes this info?
Run a
backdrop_get_messages();at the end of the saving loop. That will clear the message queue.
