How do you say whats your name and french?

There are two ways to say "What's your name?" in French, depending on formality:

Formal:

* Quel est votre nom? (pronounced: kel eh votr nohm)

Informal:

* Comment t'appelles-tu? (pronounced: koh-moh ta-pel-too)

You would use the formal form when addressing someone you don't know well, such as a stranger, an elder, or someone in a position of authority. The informal form is used with friends, family, or people you know well.
