@creatyfco would you mind posting the code snippet you used with this hook to change the order status to “on hold”?
I’m trying to do exactly the same thing on my site, but I’m still a beginner when it comes to learning PHP.
However, if I see a snippet of code using this hook, I think I’ll be able to figure out how to use it within my own website.
I hope this isn’t too much to ask. Would really be grateful for the help though.
