2 Words In First Name Field


when clients are filling First Name field, I need it to be obligatory to place 2 words, not just 1.

So, instead of First name just JOE, it need to be JOE DOE.

I need system to show warning message that First name field is not field correctly if there is just 1 word.

Any idea?



I've recently spoke with @Ikoshkin about this. Maybe he will have the answers if it's possible in the current system.
