I've been using the Form2Mail Dreamweaver extension since I don't know the PHP language at all, and it's been working pretty well, although I've been getting spams lately so I added a Captcha key, but I wanted to keep the key simple (reCaptcha can be hard to read sometimes). So I believe the robots can still decode it.
All the spam I've been receiving have one thing in common: the phone number field is filled by random letters. Is there anyway to edit the PHP so that if the phone field does not have numbers it goes to the error page?
The field still needs to accept spaces, "+", "-" and".". I also want to work if it is blank, only blocking anyone filling it with only letters.
I'd appreciate very much if someone could help me out, let me know if you need more information.Here is the code. Sorry guys, too many characters to paste it here.
