integrate CAPTCHA into PHP code form/ some jscript validation code

[login to view URL] there is a 'free repair quote' tool/service on the front page. need to start implementing some anti-spam measures. (2) that come to mind are integrating CAPTCHA on the form before the request is submitted and writing some jscript validation code to require 5 digit zip code input on 1st popup window and an email address validator on the 2nd? popup. I have downloaded a GPL version of CAPTCHA and get as far as having the image block displayed but do not have the logical skills to integrate into the exisitng php class/function. the jscript validation for the zip code popup search box should validate that there is a minimum of 5 numbers entered in order to prevent someone from entering something like '234' which would return? too many? results that could be possibly exploited by a spammer. I will provide further details as neccessary. all backend code is PHP ## Deliverables Rent A Coder requirements notice: As originally posted, this bid request does not have complete details.
