RECAPTCHA for submit

[momo]

Thanks ruptan for all the work that was done on this. After reviewing your post and the attached files, I noticed an error in the post that was not in the attached files. I also modified the behavior so that when a user enters an invalid Captcha, the user will return to the same page with the error message from recaptcha.

First, I am using Pligg 9.9.0

Step 1: Open submit_step_2.tpl:

Find :

PHP Code:

<input type="submit" value="{#PLIGG_Visual_Submit2_Continue#}" class="submit" /> 


BEFORE THIS PLACE:

PHP Code:

            <?php 
                require_once(captcha_captchas_path . '/reCaptcha/libs/recaptchalib.php');
                $publickey = get_misc_data('reCaptcha_pubkey'); // you got this from the signup page
                echo recaptcha_get_html($publickey);
            ?>

(this code was found in modules->captcha->captchas->recaptcha->captcha.tpl)
Step 2: Open Submit.php (this is where the typo is on ruptan's post).

Find:

PHP Code:

// submit step 2

function do_submit2() {
    global $db, $main_smarty, $dblang, $the_template, $linkres, $current_user; 


AFTER THIS PASTE:

PHP Code:

//captcha
if(enable_captcha == 'true') {
            
        require_once('recaptchalib.php');        
        // Get a key from http://recaptcha.net/api/getkey
        $publickey = "YOURPUBLICKEY";
        $privatekey = "YOURPRIVATE";
        
        # the response from reCAPTCHA
        $resp = null;
        # the error code from reCAPTCHA, if any
        $error = null;
        
        # was there a reCAPTCHA response?
        if ($_POST["recaptcha_response_field"]) {
                $resp = recaptcha_check_answer ($privatekey,
                                                $_SERVER["REMOTE_ADDR"],
                                                $_POST["recaptcha_challenge_field"],
                                                $_POST["recaptcha_response_field"]);
                
                if ($resp->is_valid) {
                        echo "Succesfully verified that you are human.";
                } else {
                        # set the error code so that we can display it
                        $error = $resp->error;

                }
        }    
            
        if (!$resp->is_valid) { // if incorrect captcha code was entered
              echo $error;
            do_submit1();
            return;
        }
        // fin capthca 


Step 3:

In Submit.php,

FIND:

PHP Code:

}

// submit step 3 


REPLACE WITH:

PHP Code:

} }

// submit step 3 


In Summary: The code listed on the site for submit.php incorrectly places new captcha code in such a way that the function do_submit2() never gets created. However, the code listed in the attachment is correct. If you don't look at that code, you will not get this to work. I also changed the behavior so that if it is a human who typed wrong, they can refill the submit page.

Thanks again for even figuring this stuff out, I hope that this post clarifies some of the issues you may encounter getting this to work.

Kudos also goes to ednet, who had a similar post. His showed me the typo I pointed out...
