niche 137 Posted July 16, 2012 Report Share Posted July 16, 2012 Please post the script you have so far. Otherwise, it's impossible to answer your question in a way that will be useful. If you need to write a script, you've come to the right place, but you have to tell us about your capabilities. Quote Link to post Share on other sites
Krewe 51 Posted July 17, 2012 Report Share Posted July 17, 2012 (edited) Niche there really is no need for his code for this simple question. Alright Tosti,The first step is going to be to just add a text input field at the end of the contact form before your submit button. The code will look similar to this. <p>What is 2+2?</p><input type="text" name="answer" id="answer" /> Then in your php code at the top you will need to have a validate process after you verify the form has been sent. Something like this... <?phpif(isset($_POST['submit'])){if(isset($_POST['answer']) && $_POST['answer'] == 4){#Right answer was given continue with submitting form}else{#The wrong answer was given give an error message.}}?> That's it. Any questions just ask.Krewe Edited July 17, 2012 by Krewe Quote Link to post Share on other sites
niche 137 Posted July 17, 2012 Report Share Posted July 17, 2012 (edited) Posting something similar was was my first impulse, but I noticed it was only their second post. I thought it reasonable to understand whether "his" contact form is really his or someone else's. IMO, this answer has a bearing on how to help him.

IMO, this answer has a bearing on how to help him.But I barely gave him any info I just gave him the format and the theory of how too.If we have his code then it makes it so he does no work. I just gave him suggestions where to put it and a guideline of how to do it.If he has to have the knowledge to *SUCCESSFULLY* integrate it into his form he'll be fine and keep working. If he doesn't he'll be back... Edited July 17, 2012 by Krewe 1 Quote Link to post Share on other sites
birbal 168 Posted July 17, 2012 Report Share Posted July 17, 2012 You should use any image CAPTCHA. the reason we use these for preventing bot access. bots almost can't read image but they can read every textual content. so it will be not hard for them figuring out the correct answer.

niche 137 Posted July 17, 2012 Report Share Posted July 17, 2012 (edited) Agreed. As Denny Crane says, "same team!". Good answer Krewe. Edited July 17, 2012 by niche Quote Link to post Share on other sites

justsomeguy 1,135 Posted July 17, 2012 Report Share Posted July 17, 2012 Bots certainly can read images, sometimes with better accuracy than humans. Bots are also able to crack audio captchas by using speech-to-text translation. http://arstechnica.com/security/2012/05/google-recaptcha-brought-to-its-knees/ 1 Quote Link to post Share on other sites
