How can I edit the code so it doesn't show up when posting new topics? Or could we get an update where this is an option in the admin section? Great work by the way. Appreciate your effort. zennie on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-4861 Tue, 03 Nov 2009 18:11:04 +0000 zennie 4861@http://bbpress.org/plugins/ The idea is awesome, I like that it's very fast and it doesn't torture the user with indecipherable words, but I think it's not very difficult to make a bot that can crack it, especially if there are not may different types of puzzles. However, as long as it's not well-known and well-spread, it's safe, mostly because no one takes the time to build a bot for it. deko on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-4661 Wed, 30 Sep 2009 00:05:11 +0000 deko 4661@http://bbpress.org/plugins/ I discovered Clickcha yesterday. Seems to be working well so far. Would be nice if there was a developer forum or programmer's reference. This has a lot of potential as a comment spam prevention tool. The problem I had with Clickcha was that it broke my CSS and caused the page to fail HTML validation. Here's how I fixed it: 1) Go to your wp-content/plugins directory and edit clickcha.php (about line 155) Remove all style directives--that is, everything between (and including) the <code><style></code> tags. Paste it in notepad for now--you'll want it later. 2) remove the <code><noscript></code> and <code>small></code> tags (and anything in between) that appear near the javascript code within the <code>clickcha_comment_form</code> function. Below is how my <code>clickcha_comment_form</code> function looks after editing. <blockquote>Note the <code>/* <![CDATA[ */ ... /* ]]> */</code> addition. This tells HTML validator to ignore the script.</blockquote> <pre><code>function clickcha_comment_form($post_id) { $public_key = get_option('clickcha-public-key'); $help_text = get_option('clickcha-help-text'); if(empty($public_key)) { echo "<div id='message' class='error fade'>Clickcha is not yet active. Please enter Clickcha API keys in settings.</div>"; } // Bypass clickcha for logged-in user (except 'subscriber') else if(!current_user_can('level_1')){ ?> <input type="hidden" name="clickcha_token" id="clickchatoken" value=""></input> <?php echo $help_text; ?> <input type="image" name="clickcha" id="clickcha" alt="" src=""></input> <script type="text/javascript"> /* <![CDATA[ */ function clickcha_token(token) { document.getElementById('clickchatoken').value = token; document.getElementById('clickcha').src = 'http://api.clickcha.com/challenge?key=<?php echo $public_key; ?>&token=' + token; } function clickcha_get_token() { var e = document.createElement('script'); e.src = 'http://api.clickcha.com/token?output=json&key=<?php echo $public_key; ?>&rnd=' + Math.random(); e.type= 'text/javascript'; document.getElementsByTagName('head')[0].appendChild(e); } clickcha_get_token(); // Firefox's bfcache workaround window.onpageshow = function(e) {if(e.persisted) clickcha_get_token();}; /* ]]> */ </script> <?php } }</code></pre> 3) Edit your stylesheet and put in what you took out of clickcha.php: here's how it looks in my stylesheet: <pre><code>#clickcha input { height: 100px; width: 200px; border: 0; margin: 0; padding: 0; display: block; } #submit { display: none; } #commentform input [type="submit"] { display: none; } #commentform button [type="submit"] { display: none; } #commentform span.submit { display: none; }</code></pre> Clickcha is working, my CSS looks like it should, and the page validates as XHTML 1.0 Transitional. loungelizard777 on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-4592 Wed, 23 Sep 2009 12:49:05 +0000 loungelizard777 4592@http://bbpress.org/plugins/ I've installed Clickcha but when I try to test-register I get this error message ... Anyone knows what I have to do to get this working? The other two worthy bbPress Antispam plugins were useless, Russian spammers went through them like hot steel through butter. But Clickcha seems to prevent them.

(If so, how, because it hasn't on my site). thanks Nightgunner5 on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3344 Wed, 06 May 2009 22:33:05 +0000 Nightgunner5 3344@http://bbpress.org/plugins/ <a href="http://api.clickcha.com/getkeys?url=FORUMADDRESS&email=you@example.com" rel="nofollow">http://api.clickcha.com/getkeys?url=FORUMADDRESS&email=you@example.com</a> Copy that down because you'll never be able to use the same url and email to get a key again. mentatseb on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3343 Wed, 06 May 2009 21:02:26 +0000 mentatseb 3343@http://bbpress.org/plugins/ Hi, is there an alternative way to get the API key?

Gonna change that behavior soon. <blockquote> Also, couldn't someone use one captcha over and over? </blockquote> No, the Captcha expires when the solution (correct or incorrect) is submitted for verification. Thanks for the feedback Nightgunner5! Nightgunner5 on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3276 Mon, 27 Apr 2009 22:45:40 +0000 Nightgunner5 3276@http://bbpress.org/plugins/ If someone loads a captcha image multiple times, the circle with the correct answer stays in the same place. I suggest using urls that expire immediately after use to prevent spam bots from exploiting this "feature". Also, couldn't someone use one captcha over and over? iDope on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3266 Mon, 27 Apr 2009 06:32:19 +0000 iDope 3266@http://bbpress.org/plugins/ Thanks for letting me know. I have fixed it. It was barely any work porting it to bbPress, except bbPress doesn't have as many hooks so I had to use a more generalized hook 'bb_init'. _ck_ on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3255 Sat, 25 Apr 2009 05:53:42 +0000 _ck_ 3255@http://bbpress.org/plugins/ I see a stray wp_die in there, you'll have to replace it with bb_die Thank you for porting your plugin from WordPress, I wish more authors did that. iDope on "Clickcha" http://bbpress.org/plugins/topic/clickcha/#post-3252 Fri, 24 Apr 2009 12:44:02 +0000 iDope 3252@http://bbpress.org/plugins/ Clickcha is a very unique & secure CAPTCHA that requires just one click instead of typing characters.
