@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)"
