Posted: Sat May 26, 2007 4:11 pm Post subject: RE:Captcha - Stop Spam, Read Books and protect email address
This is a Captcha Turing Test for your blog but it results in a much nicer looking image with advanced reload image and audio options. However you DO NOT need the GD library installed or a server with TT-Font compiled (as I discovered was required) so it should work on slightly more set-ups. Recaptcha also uses the captcha to correctly digitise old books where OCR has failed. So you know that the distorted text is specifically difficult for computers to read. How this works is explained in depth on the site. Furthermore you can lock email address links behind a captcha link to prevent bots. You will need to visit http://recaptcha.net/ and grab a private/Public key for your domain and you may also need to go to http://mailhide.recaptcha.net/apikey to generate a mailhide key pair. This is all free and takes not very long. I used the original Captcha plugin as a framework so it has the same flexability of sometimes or all the time and the same spam API awareness. By default both actions are carried out currently so you will want to get both pairs of keys. For some reason the default skin messes up the box and this cost me a good few hours wondering why the CSS was not working. Finally I dscovered that it was a bug of the fact that my browser was following CSS rules that are generally ignored during rendering. I found a fix (also used by the captcha but broken by the default CSS.  There is an option (On By Default) that applies a not too vaild under xHTML hot fix.
For many skins it should be possible to do without the fix. If it is needed fussy coders can add this style statement to thier own sheet but must user "!Important" to force it. Oh yes, plugin download: http://freestuff.lordmatt.co.uk/my_downloads/NucleusCMS%20Stuff/ It's a little under 9KB in size. Unzip, upload as is to plugin directory. Install. Edit Options and add your keys. Rock and Roll. BTW: Not recomended for use with other Captcha plugs... _________________ Host Plugins | Blog | Hundred Quid A Day | My Big Fat Arse |

Posted: Sat Mar 23, 2013 7:00 pm Post subject: Fixing (does not support SqlTablePrefix) problem
First, I cannot believe I figured this out, and I'm sure than anyone who has ever read one of my posts to this forum can't believe it either. I got the clue from Lord Matt's "My Bad" casual reply, like it must be something really minor. So I went looking through the NP_REcaptcha.php file and read it. I noticed there is a part "function supportsFeature" and what seems to be a list of features supported. One of them was SQlTablePrefix. I noticed that the other features had something after them like return:0, so I added return:0 after SqlTablePrefix. No dice. It still didn't work. So, I changed the "O" to "1", and it worked. So, this is what I have now: function supportsFeature($what) { switch ($what) { case 'SqlTablePrefix': return 1; case 'HelpPage': return 0; |
