I attempted to do something like this but it was rather advanced for my php skills. However, on WP’s forum I found a member who was extremely helpful and he provided the coded which was one of the methods I was attempting to use. Here is the link for those who may need it.
Please note that this is for the Contact Form 7 plugin in WP and you’ll need to modify the text.php file under the Validation filter comment (line 113) in the modules folder.
Thank you ccc630 for all your suggestions, they were very helpful and I learned a little more about php.
