Maybe just put another layer which is a simple sum, i.e. generate tqo random numbers between 1 and 9 and have the user enter the simple addition?

Thanks for the idea Skorpios, but that wouldn't stop a person from submitting the form every 7 seconds.

set a cookie on the form page,
when the form is submitted, set the cookie value to sent or somesuch - reject all subsiquent form submissions where the cookie value is already 'sent'

... or record the ip address when a form is submitted, don't allow that ip address to submit the form again for whatever time period you chose.

Thanks topr8! I like the second idea better.

@topr8: I have recorded the ip address. How can I code the time period of submitting the form again?
If I understand correctly this will prevent an contineous submitting of the form during the time set in the code.
I assume with an if else statement.
I am new to php so just logical thinking and I could be completly wrong.

On send you could add a variable $sent = "true";
On the main page...
If ($sent == "true")
This should prevent repeated submits of the form.
