Regular expression for first and last name

Question

For website validation purposes, I need first name and last name validation.

For the first name, it should only contain letters, can be several words with spaces, an

Answer 1

First name would be

"([a-zA-Z]{3,30}\s*)+"

If you need the whole first name part to be shorter than 30 letters, you need to check that seperately, I think. The expression ".{3,30}" should do that.

Your last name requirements would translate into

"[a-zA-Z]{3,30}"

but you should check these. There are plenty of last names containing spaces.
