Question : reCAPTCHA PHP not failing when nothing is entered; works fine when something is entered

Hi Experts,

I have a form that uses reCAPTCHA to all users to submit tags describing an ad. If I complete the captcha, it works fine, and the new tag is added. If I don't enter anything, the nothing works, but I don't get an error message. The attached file is the processing for the tag submission.

The attached code snippet is from the actual form.
 
action-add-tag-submit.php (1 KB) (File Type Details) 
Form processing code for captcha
 


You can see the form at work here:

Feel free to submit tags or whatever, This is a dummy copy of the site.

Thanks for the help!
