The validation code

I copied the contact form, couple issues:

1.  The client side validation code coped from https://mdbootstrap.com/docs/jquery/forms/contact/

This does not work using 'status'

"getElementById('status')"

I changed to the actual element name, like 'email', then no complaints, BUT, 
only the last one for message actually displays the warning. 
How do i fix this?


2. Any examples of server side validation using PHPMailer, not sendmail?

Thx.
