| Local Math Captcha Hack (to provide more protection against spams) |
| by irmtfan on 2013/4/15 8:44:49 Local Math Captcha Hack - irmtfan - http://www.xoops.org - http://www.xoops.ir =========================== This is a very simple hack to change the XOOPS math captcha from figures to local words to provide more protection against spams. Example: {3} + {4} = ? will be changed to {three} + {four} = ? in english This hack had been introduced about one year ago in XOOPS255 persian release and was completely effective in persian websites. eg: I had not one single spam in my website for more than a year while previously I had 5 or 6 daily spams. I hope this hack will be useful in other local communities and even english websites. Please try it and report the result in xoops.org forums. Install -------------------------- Just copy 2 files in this package 1- ./htdocs/class/captcha/text.php 2- ./htdocs/language/english/locale.php Note: -------------------------- In XOOPS255 the captcha is set to "image" by default. You should change the captcha mode to "text" in XOOPS255/class/captcha/config.php le="color: #000000"><?php 'mode' => 'text', // default mode, you can choose 'text', 'image', 'recaptcha'(requires api key) You can back to old figures by changing the setting in ./htdocs/language/english/locale.php le="color: #000000"><?php define("_NUM_TYPE","word"); // you can choose "figure","word","image" ] Translation: ---------------- You can implement this hack for your own language by: 1- Copying ./htdocs/language/english/locale.php into ./htdocs/language/YOUR_LANG/locale.php 2- Translate figures to your own language (currently you only need to translate 1-9): le="color: #000000"><?php $_numWords = array( '0'=> '' , '1'=> 'one' , '2'=> 'two' , '3' => 'three', '4' => 'four', '5' => 'five', '6' => 'six', '7' => 'seven', '8' => 'eight', '9' => 'nine', '10' => 'ten', '11' => 'eleven', '12' => 'twelve', '13' => 'thirteen', '14' => 'fouteen', '15' => 'fifteen', '16' => 'sixteen', '17' => 'seventeen', '18' => 'eighteen', '19' => 'nineteen', '20' => 'twenty', '30' => 'thirty', '40' => 'fourty', '50' => 'fifty', '60' => 'sixty', '70' => 'seventy', '80' => 'eighty', '90' => 'ninty', '100' => 'hundred &', '1000' => 'thousand &', '1000000' => 'million', '1000000000' => 'billion'); TO DO: --------------------- show numbers as figure images.
