I currently have a php contact form on my website and its starting to get alot of spam. The form has 4 fields (name, email, subject, message). It uses PHP to submit and Javascript to error check to make sure fields are filled in.
To help eliminate spammers I want to have a random number generated when the form page is loaded and I want the user to have to enter this random number correctly to submit the form. I dont want captcha as my webhost doesnt have the gdlibrary installed.
I need this quickly.
