fail response without reloading form
Bonny
I put reCAPTCHA at the end of my form. When the answer is not correct
the page reloads again with fields reset. Does any one know how to
keep the fields still filled, and display a message saying something
like " Please reEnter your answer..." or something like that when
there's a failed answer? Below is my code and thanks a million !!
-----code-------
<?php
require_once('recaptchalib.php');
define('PUBLIC_KEY', 'my public key');
define('PRIVATE_KEY', 'my private key');
$error = null;
if ($_POST["recaptcha_response_field"]) {
$response = recaptcha_check_answer(
PRIVATE_KEY, $_SERVER['REMOTE_ADDR'],
$_POST['recaptcha_challenge_field'],
$_POST['recaptcha_response_field']
);
if ( $response->is_valid ) {
//this is my mailer function//
$to = "bla...@gmail.com";
$subject = "Hinc Showroom Website Feedback";
$first_name_field = $_POST['first_name'];
$last_name_field = $_POST['last_name'];
$dropdown= $_POST['drop_down'];
$email_field = $_POST['email'];
$phone = $_POST['phone'];
$adress = $_POST['address'];
$city = $_POST['city'];
$state = $_POST['state'];
$zipcode = $_POST['zipcode'];
$message = $_POST['message'];
$signup = $_POST['signup'];
$body = "From: $first_name_field $last_name_field
\n Status:$dropdown\n Email:$email_field\n Phone: $phone\n Address:
$adress\n City:$city\n State: $state\n Zipcode: $zipcode\n Message:
$message\n Sign up for newsletter:$signup\n";
header('Location: home.php');
mail($to, $subject, $body);
//end of my mailer function//
}
else {
$error = $response->error;
}
}
echo recaptcha_get_html( PUBLIC_KEY, $error );
?>
-----code end here------
Thank you again!

steps here.
Having said that, I have the same problem as the original poster with
my Wordpress blog, but the answer doesn't make any sense to me. I
don't know how to echo back the values of the fields in the HTML I
generate. I checked the documentation, but couldn't understand that
either. As I said, I think I'm a coding moron.
On a related note, I am not getting an error message generated
either.
So, can you please tell me exactly what to put in the code below, and
exactly where it should go so that I get (1) an error message telling
people to try again, and (2) their comment reappearing in the comment
box so they don't have to retype it? Thanks.
Ideally, just paste the correct code sections as a reply.
Here is my recaptcha code (with the keys removed):

I tried to enter a false comment, and it worked properly, both saving
my comment and telling me I had entered the words incorrectly.
So I posted a comment asking the owner of the blog to send me his
recaptcha code, which he gladly did. I then compared his code with my
code line by line. Aside from the public keys, there was not a single
difference between the two. My code exactly resembles his letter for
letter.
So, the problem must be with my WordPress theme/template? I really
like my template, and so don't just want to switch. Is there some
change I can make to the template somewhere? Maybe this is a question
I should be asking WordPress?
Any help you can offer is appreciated...

You might try using the default theme. We have seen themes causing issues before.

solution I found.
Problem was: in Wordpress plugin, a failed captcha reloaded the page
but didn't replace the comment text in the comment form, forcing the
person to rewrite it (and maybe making them think it was actually
posted).
My solution: Check for the presence and location of the comment form
API hook (which recaptcha uses to load the javascript holding the
deleted comment text). It looks like this:
<?php do_action('comment_form', $post->ID); ?>
In my case it actually WAS in the comment form, but in a slightly
different location from where it is in the default wordpress theme.
Putting it at the end of the form immediately before the </form> made
the comment form load the text as expected.
<p id="submit">
<input name="submit" type="submit" tabindex="5" value="Post
Comment" />
</p>
<?php do_action('comment_form', $post->ID); ?>
</form>
Not sure if that constitutes a bug or not (the js involved seems
simple enough and I can't see why moving the hood down a few lines
would fix it but I'm not a js programmer so there you go). Having it
work so long as the hook is called somewhere in the comments template
would definitely be preferrable as many people probably experience
this bug without noticing it (i run a site with a very international
audience, who I think probably fail the captchas more than average,
and they've been complaining about censorship lately ;)
