Implementing PHP Captcha

[mikeinspain]

Hi Guys

I have a client who's existing site has a html contact form using "sps-mailsend.asp". It has a form validation script in place but is still being spammed and therefore would like to pop a "Captcha" script in.

I am uncomfortable with ASP and not sure how to perhaps intergrate PHP into this page. I have been asked to go in and tidy this site up together with some SEO work, so the original work is not my own..

I would apprecaite if someone could perhaps point in the right direction or recommend any particualr script?

Thanks

Mike

at the end, your best bet would be to put a secruity box, have random questions (or letters) appear, and validate if the inputted answer matches, if it does the form will submit, if it doesn't it halts and the form doesn't submit.

Changed thread title to better describe the problem (did you know that threads whose titles contain phrases such as 'question' actually get FEWER responses?).

Heya, Mike.

Check out re-Captcha, which has a free PHP plugin for any script here.

well if u have a database, u would have to create a table with columns (id, question, answer)...id auto increment. put simple questions (easy answers) and their answer in the table (put as many as u want).

Then in your PHP create a random number from 1 to the number of rows u have. Then create a query statement:
[PHP]$statement = "SELECT question, answer FROM valid WHERE id=".$randNum"; ";[/PHP]

if u don't have a db, use a text file, eash line would have a question(delimi ter)answer. It be the same as above just with a random line.

good luck

Isn't re-captcha the one where they're using it to create e-books? Or am I thinking of something else?
