[PHP] Adding reCAPTCHA to form using PHP
Need help with reCAPTCHA. Never installed it before.
When Submit is clicked the quoterequest-redirect.php is run but I think it
would be better to test the reCAPTCHA before the quoterequest-redirect.php
program has been run.
I check the CAPTCHA in quoterequest-redirect.php, it displays a invalid
message if invalid but the user has to tab back to fill in the CAPTCHA
again.
The reCAPTCHA show correctly but I need some help/hints/tips here.
Thanks very much again,
/Ernie

RE: [PHP] Adding reCAPTCHA to form using PHP
Thanks for your reply Tedd.
Maybe my reCAPTCHA is more complicated than it needs to be but when you
click the Submit button the form triggers the
action=quoterequest-redirect.php which goes to another program without
checking the CAPTCHA. I test in the called program and display a message if
it's invalid. The user then clicks back to form page to try again.
It would be better on submit the program would display an error message and
go nowhere.
The code works by itself but in a form with an action, not so good.
Not such how to do this
form action=quoterequest-redirect.php method=post
td
?php
// call the lib..
require_once('recaptchalib.php');
// Get a key from http://recaptcha.net/api/getkey
$publickey = 6LeGhwwAADNm2bEIkxzNHXIjpAlGYJ5NCYju;
$privatekey = 6LeGhwwAAFbi37aANuHliCnZ-_jg3uN8N7oh;
# the response from reCAPTCHA
$resp = null;
# the error code from reCAPTCHA, if any
$error = null;
# was there a reCAPTCHA response?
if ($_POST[submit]) {
$response = recaptcha_check_answer($privatekey,
$_SERVER[REMOTE_ADDR],
$_POST[recaptcha_challenge_field],
$_POST[recaptcha_response_field]);
if ($response-is_valid) {
echo Yes, that was correct!;
} else {
# set the error code so that we can display it
echo Eh, That wasn't right. Try Again.;
}
}
?
?php echo recaptcha_get_html($publickey, $error); ?
/td
input type=submit name=submit id=submit value=Submit /
