Bad Behavior is a set of PHP scripts which prevents spambots from accessing your site by analyzing their actual HTTP requests and comparing them to profiles from known spambots. It goes far beyond User-Agent and Referer, however. Bad Behavior is available for several PHP-based software packages, and also can be integrated in seconds into any PHP script. (quote from the [[http://www.bad-behavior.ioerror.us/ | homepage]]).
====Integration in wikka====
=== Bad-Behavior 1.2.x series ===
''these instructions are for version 1.2.1 but should work for the whole 1.2.x series''
~1. [[http://www.ioerror.us/software/bad-behavior/bad-behavior-download/ | download]] it
~2. unzip the file, go into the folder and make the following changes:
~3. add ##bad-behavior-wikkawiki.php## to the folder, with the following content:
%%(php;1)
config['table_prefix'].'bad_behavior_log');
define('WP_BB_CWD', dirname(__FILE__));
// Log failed requests to the database.
if ($wakka->config['bad-behavior-logging'] == 1) $wp_bb_logging = TRUE;
else $wp_bb_logging = TRUE;
// Log all requests to the database, not just failed requests.
if ($wakka->config['bad-behavior-logging'] == 2) $wp_bb_verbose_logging = TRUE;
else $wp_bb_verbose_logging = FALSE;
// How long to keep the logs around (in days).
$wp_bb_logging_duration = 7;
// Email address to contact you in case of problems
// This will be shown to users on the error page, which means it will
// be exposed to spammers! Bad Behavior will munge it automatically; you
// should NOT munge it here!
$wp_bb_email = $wakka->config['admin_email'];
//***Callbacks***
// return a UTC date in the format preferred by your database
function wp_bb_date() {
return gmdate('Y-m-d H:i:s');
}
// run a SQL query and return # of rows affected, or FALSE if query failed
function wp_bb_db_query($query) {
global $wakka;
$result = $wakka->Query($query);
if ($result === TRUE || $result === FALSE) $returnValue = $result;
else {
$data = mysql_fetch_row($result);
$query_parts = explode(" ",$query);
$mysql_statement = strtolower($query_parts[0]);
switch ($mysql_statement) {
case "insert":
case "delete":
case "update":
$returnValue = mysql_num_rows($result);
break;
case "select":
$returnValue = mysql_affected_rows();
break;
default:
if($data === FALSE) $returnValue = 0;
else $returnValue = 1;
}
mysql_free_result($result);
}
return $returnValue;
}
// Load core functions and do initial checks
require_once(WP_BB_CWD . "/bad-behavior-core.php");
?>
%%
~4. install the mysql-table (replace wikka_ in the first line with your table-prefix - must be the same as in the wikka.config!) :
%%
CREATE TABLE IF NOT EXISTS wikka_bad_behavior(
`id` int( 11 ) NOT NULL AUTO_INCREMENT ,
`ip` text NOT NULL ,
`date` datetime NOT NULL default '0000-00-00 00:00:00',
`request_method` text NOT NULL ,
`http_host` text,
`request_uri` text NOT NULL ,
`server_protocol` text NOT NULL ,
`http_referer` text,
`http_user_agent` text,
`http_headers` text NOT NULL ,
`request_entity` text NOT NULL ,
`denied_reason` text NOT NULL ,
`http_response` int( 3 ) NOT NULL ,
PRIMARY KEY ( `id` )
)
%%
~5. upload the whole folder to ##3rdparty/plugins/bad-behavior/##
~6. add the following line to ##wikka.php##
%%(php)
//load 'bad-behavior'
if ($wakka->config['bad-behavior'] == 1) require_once("3rdparty/plugins/bad-behavior/bad-behavior-wikkawiki.php");
%%
=> right before the %%(php;1171)// go !%%---
===Configuration===
add %%(php)
'bad-behavior' => '1',
'bad-behavior-logging' => '1',
%%

**bad-behavior**:
- 0: don't run bad-behavior
- 1: run bad-behavior

- 0: don't log anything
- 1: log failed request

== Issues ==
- no config-options yet.
- it probably breaks with mode-rewrite=off
- not all of the functions are finished (they require some changes which would be better located in the core), but none of these is used (at least in 2.0.10)
- I should take a look at the version from Mike (see comments below)
