Help with captcha script needed

Posted on 16th Feb 2014 by admin

Hello,

I am working on a script where reCAPTCHA or a similar form of CAPTCHA will be used, for the sake of this example I will talk about reCAPTCHA. I wanted to know how I could have the reCAPTCHA script store a value upon correctly entering a code that will be used by a different script to allow on to proceed?

A snippet of the reCAPTCHA code which will be located in a file called recaptcha.php.

Code: (text) if ($resp->is_valid) {
[b] $captcha = "1";
# in a real application, you should send an email, create an account, etc[/b]
} else {
# set the error code so that we can display it. You could also use
# die ("reCAPTCHA failed"), but using the error message is
# more user friendly
$error = $resp->error;
}
}

I bolded the part of interest, how would I be able to use a variable like

Code: (text) $captcha = "1";
In a completely different file that is called login.php to allow one to login if the captcha is correct? The value would only be needed for that session of course. I want to use this method because the captcha script might be used in multiple locations so I figure this route would be easier and allow for quicker modifications than have the script called each time in different files for instance.

The only alternative I can think of is using MySQL or local files to store the answer but that won't be very logical for a script that could have hundreds of requests an hour.

Any help would be appreciated, thanks in advance
