Client-side validation is easy to bypass, but server-side validation should not.

I mean that client-side validation may work with human users but spam bots may send requests to your server bypassing your form or they even don't understand JavaScript.

Do the whole client-side validation for human users but repeat the same validation in the server-side so no one will be able to bypass your rules.
