RECAPTCHA for submit

[fhelik]

Ok these are the steps to get the Recaptcha in the submission page, so every user has to fill the captcha in order to continue with the submission. /

You will end up with something like this: (check the attachment)

(Before start you will need a Recaptcha keys, to get them go to recaptcha register and get the key, also download the recaptchalib.php from the same site and save it in your pligg base folder)

(Before we start make sure the User Registration Captcha is "true" under the admin, configuration, Captcha)

Step 1: open submit_step_2.tpl

Look for this:

 <input type="submit" value="{#PLIGG_Visual_Submit2_Continue#}" class="submit" /> <input type="hidden" name="url" id="url" value="{$submit_url}" /> <input type="hidden" name="phase" value="2" /> <input type="hidden" name="randkey" value="{$randkey}" /> <input type="hidden" name="id" value="{$submit_id}" />

Right before that insert this( remember to change YOURPUBLICKEY for yours):

         {php} 		
			require_once('recaptchalib.php');
			$publickey = "YOURPUBLICKEY"; // you got this from the signup page
			echo recaptcha_get_html($publickey);
		{/php}

Now open submit.php

look for this:

PHP Code:

check_actions('do_submit1');
    $main_smarty->display($the_template . '/pligg.tpl');
}

// submit step 2 


right after insert this (remember to change YOUR PUBLIC AND SECRET):

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
            $main_smarty->assign('register_error_text', "badcode");
            $main_smarty->display($the_template . '/register_error.tpl');
            return;
        }
        // fin capthca 


a little below look for this:

PHP Code:

}

// submit step 3 


and replace it with this: ( I just added one more } )

PHP Code:

}}

// submit step 3 


Before start make backup of these 2 files, in case you make a mistake.
I made this from a code I found there in pligg, plus the resources of Recaptcha.net and recaptcha group.

I hope this helps, and work, please leave a comment after installation.

I don't know what people are doing wrong, but for those here are the files. remember to do the backup of the 3 files before replace. NOTE i am using yget template on indipop.net

check the attachment for the files.

ok I hope it works for you guys. please post here if success

Awesome! Going to give it a shot right now...

Hmmm, I get a blank page after the captcha is entered and I hit submit. Could there be a syntax error?

make sure you have the reCAPTCHA Library, put it in the pligg base folder. (if the gaptcha appears, maybe is not this)

check that you have /register_error.tpl in your template folder

try this:
go to admin language find this: "PLIGG_Visual_Register_Error_BadCode", make sure is some text there.
1: submit 1 story and fill the gaptcha correct. It should go to next step.
2: submit 1 story and fill the captcha wrong. it have to show the error

NOTE: I use yget template. look in indipop.net, it is working fine. both for registration and submit.

check the post I just upload my files, make backup and replace, i hope this works.

Hello; I haven tried it out but just my thought, we should put the captcha at the submit step 3. It is much better, because my user go back to change something, he has to enter the captcha again. Meanwhile at step 3, you onyl need to enter once.

Thanks

I'm reveiving the same, but I think placement would make more sense in submit 3.

So I see why you would want reCaptcha for adding new stories but what about the first step which is when they register? Wouldn't that alleviate the problem of spam bots creating accounts?

This works for me.

1) In register_center.tpl add this:

{if isset($form_captcha_error)}{ foreach value=error from=$form_captcha_error }<br /><span class="error">{$error}</span><br />{ /foreach }<br />{/if}

{php}
require_once('recaptchalib.php');
$publickey = "..."; // you got this from the signup page
echo recaptcha_get_html($publickey);
{/php}

BEFORE THIS

<input type="submit" name="submit" value="{#PLIGG_Visual_Register_Create_User#}" class="log2" tabindex="36" />

2) In register.php add this:

require_once('recaptchalib.php');
$privatekey = "...";

$resp = recaptcha_check_answer ($privatekey,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);

if (!$resp->is_valid) { // if both captchas don't match
$error = true;
}


BEFORE THIS

$vars = array('username' => $username);
check_actions('register_check_errors', $vars);

AND THIS

$main_smarty->assign('form_captcha_error', 'The reCAPTCHA code you entered was incorrect.');

AFTER THIS

$main_smarty->assign('form_password_error', $form_password_error);
