I receive mails with all fields empty

Hi
I have a form with some fields all required and Google Captcha code.
​
Sometime we receive an email with empty fields. I don't know how as I ccanot reproduce the issue.
I guess it is a spam.
​
How can I avoid this situation?
​
Thanks

Hi giulia72,
​
The main thing is to enable serverside validation to check for the empty fields.

Hi Bob
Thank you for you answer
is there a documentation or article to follow how to configure it?

Hi
it is possible to receive a documentation or some screenshots about how to configure it
​
Chronoform is very powerful but the weakness is the documentation: it is very poor or inexhistent!!!

Hi giulia72,

Please check the FAQ here

Hi, how did you solve this? Did setting server validation help? It didn't to me.

Hi
yes it seems to work for the moment

Hi giulia72,Please check the FAQ hereBob

That link explains serverside validation for ChronoForms v4 and ChronoForms v5, how about v6? I'm following the steps here but not working for me https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&ved=2ahUKEwiFj8S9hNvoAhUvwcQBHZ6yCooQFjACegQIAxAB&url=https%3A%2F%2Faccesoriosgoldwing.com%2Fproduct%2Fdownload%2Ffile_id-1297&usg=AOvVaw20OGzLiPi2NvMScWd4moN2

​
What am I doing wrong?
​

I use chronoforms v.5 not 6
I'm afraid I cannot help you
