@Martijn "I am not sure how to best communicate this error to the user though. It would just look like something randomly failed?"
I just thinking.
After add the code.
`strpbrk(NAME, " ") === false`.
Maybe I need tu change the Name field : Your Name to Your Name (without space).
And without give error to the user. So I don't need to put
echo "error" / "Your Name (without space)"
