reCAPTCHA PHP to stop spam

69 New Member
Hi,

Has anyone used this successfully in PHP to prevent spam mails sent from HTML forms? I've added it to a form of mine and it seems a bit hit and miss. I incorrectly enter the captcha and it correctly says its incorrect. I try again with another incorrect response and it accepts it?

Am I doing something wrong or is there a problem with reCAPTCHA?

Thanks,

Sean

Hi Sean.

There must something be a little of for it to act like that. It could simply be that you overlooked some minor detail when you wrote your code.

Did you write the code from scratch or are you using something you got from somewhere else?
Could you show us the code that is likely to be causing this behavior?

Hi Thanks, yes my code is as follows. I'm using Smarty with PHP.

At the top of the PHP file:

Expand|Select|Wrap|Line Numbers
  1. require_once('includes/recaptcha-php-1.9/recaptchalib.php');
  2.  
  3. $privatekey = "6LeYowAAAAAAAMiylx8fE5Hs85ZfX7KraUler1gi";
  4. $publickey = "6LeYowAAAAAAAFLqbuAe3Byvu98D0EQAZuyvSVH2"; // you got this from the signup page
  5. $smarty->assign( 'recaptcha', recaptcha_get_html( $publickey ) );
  6.  
To process the form:

Expand|Select|Wrap|Line Numbers
  1. $resp = recaptcha_check_answer ($privatekey,
  2.     $_SERVER["REMOTE_ADDR"],
  3.     $_POST["recaptcha_challenge_field"],
  4.     $_POST["recaptcha_response_field"]);
  5.

Lo all, Ok - I'm adding site search functionality to a database driven website. I have a list of 390 stop/ignore words, having looked at ASPFAQ already I see that the example uses an array, what I was wondering was whether this would still be the best practice for this quantity of stop words? There is a larger over head in me defining the array initially as I will have to hard code them all in, alternatively I thought I could import...

Hello, I have been using VB.NET for about 5 months and now I decided it's time to start using C#.NET because I like the syntax setup alot more, because it more closely resembles php/perl which are my string points. I am trying to debug a project, in VB.NET i could put in a "Stop" statement to make the debugger stop at that point, then i could use F10 and F11 to step through the code.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
