Adding Challenge Questions
I am trying to figure out how to add 2 challenge questions to my single.php file. I want to replace the
"add the numbers" with the two challenge question because I have too many spam-bots getting through to people who have posted ads.
I figured out how to get one question going, but I can NOT figure out how to add a second question. Whatever I name the second question it will NOT validate it properly. For some reason the only name that works is the
name="term"; which I used for the first challenge question. I tried to add a second question and name it
name="term2" for example, but it does NOT validate even after I add it to the
$email_err . section of the code below.
My hope is that having two simple challenge questions, each with 8 possible answers in a dropdown box, that spam-bots will not be able to guess the 2 correct answers at the same time; therefore spam-bot emails will NOT get sent to ad posters.
Here is how I have the
Contact Ad Owner set up now if you need to see what I am trying to do:

As you can see right now for emails to be sent they have to answer the question
What color is the sky? and enter the
add the numbers. So I would like to remove the add the numbers and replace it with a second simple challenge question.

Below highlighted in red is the code I am currently using for the first challenge question:
