Hi,
This topic has already been discussed.
But exist today a solution to remove the fields that no longer exist from the content, automatically?
It’s boring to do it manually, each time.
Maybe a plugin or a hook? Is possible?
Why do you keep adding and deleting this question?
The answer is already in the topic that you link to and where you originally posted. You can write a script that does the job. A hook doesn’t make that much sense because you would have to do something with the file for the hook to kick in. I don’t know of any plugin.
To completely automate this, you would have to parse the blueprints. And then use a cron job that looks for changes in blueprints.
