Robots are not correctly filtered.

There’s a bug in the code, this function:

public function Check_Spiders() {

			$spiders = array("Teoma", "alexa", "froogle", "Gigabot", "inktomi", "looksmart", "URL_Spider_SQL", "Firefly", "NationalDirectory", "Ask Jeeves", "TECNOSEEK", "InfoSeek", "WebFindBot", "girafabot", "crawler", "www.galaxy.com", "Googlebot", "googlebot", "Scooter", "Slurp", "msnbot", "appie", "FAST", "WebBug", "Spade", "ZyBorg", "rabaz", "Baiduspider", "Feedfetcher-Google", "TechnoratiSnoop", "Rankivabot", "Mediapartners-Google", "Sogou web spider", "WebAlta Crawler","TweetmemeBot", "Butterfly","Twitturls","Me.dium","Twiceler", "Yammybot", "Openbot", "Yahoo", "ia_archiver", "Lycos", "AltaVista", "Googlebot-Mobile", "Rambler", "AbachoBOT", "accoona", "AcoiRobot", "ASPSeek", "CrocCrawler", "Dumbot", "FAST-WebCrawler", "GeonaBot", "MSRBOT", "IDBot", "eStyle", "Scrubby");

			foreach($spiders as $spider) {
				if(strpos($this->get_UserAgent(), $spider) == true)
					return true;
			}

			return false;
		}

which detects the spiders is using get_UserAgent() which only returns the browser type, it should instead be using the user agent variable as so:

public function Check_Spiders() {

			$spiders = array("Teoma", "alexa", "froogle", "Gigabot", "inktomi", "looksmart", "URL_Spider_SQL", "Firefly", "NationalDirectory", "Ask Jeeves", "TECNOSEEK", "InfoSeek", "WebFindBot", "girafabot", "crawler", "www.galaxy.com", "Googlebot", "googlebot", "Scooter", "Slurp", "msnbot", "appie", "FAST", "WebBug", "Spade", "ZyBorg", "rabaz", "Baiduspider", "Feedfetcher-Google", "TechnoratiSnoop", "Rankivabot", "Mediapartners-Google", "Sogou web spider", "WebAlta Crawler","TweetmemeBot", "Butterfly","Twitturls","Me.dium","Twiceler", "Yammybot", "Openbot", "Yahoo", "ia_archiver", "Lycos", "AltaVista", "Googlebot-Mobile", "Rambler", "AbachoBOT", "accoona", "AcoiRobot", "ASPSeek", "CrocCrawler", "Dumbot", "FAST-WebCrawler", "GeonaBot", "MSRBOT", "IDBot", "eStyle", "Scrubby");

			foreach($spiders as $spider) {
				if(strpos($_SERVER['HTTP_USER_AGENT'], $spider) == true)
					return true;
			}

			return false;
		}

Hi,

I applied the proposed fix but didn’t get any improvement.
I have still a lot of robots in my stats.

Regards.

I found several more issues over the last few days, I’ve sent a patch in to the author so it should be fixed in the next release.

Replace everything in hits.class.php with the following:

<?php
	class Hits extends WP_Statistics {

		public $result = null;

		public function __construct() {

			parent::__construct();
		}

		public function Visits() {

			global $wp_version;

			// If we're a webcrawler or referral from ourselves, don't record the visit.
			if( !$this->Check_Spiders() && !( $_SERVER['HTTP_USER_AGENT'] == "WordPress/" . $wp_version . "; " . get_home_url("/") || $_SERVER['HTTP_USER_AGENT'] == "WordPress/" . $wp_version . "; " . get_home_url() )  ) {

				$this->result = $this->db->get_row("SELECT * FROM {$this->tb_prefix}statistics_visit ORDER BY <code>{$this->tb_prefix}statistics_visit</code>.<code>ID</code> DESC");

				if( substr($this->result->last_visit, 0, -1) != substr($this->Current_Date('Y-m-d H:i:s'), 0, -1) ) {

					if( $this->result->last_counter != $this->Current_Date('Y-m-d') ) {

						$this->db->insert(
							$this->tb_prefix . "statistics_visit",
							array(
								'last_visit'	=>	$this->Current_Date(),
								'last_counter'	=>	$this->Current_date('Y-m-d'),
								'visit'			=>	$this->coefficient
							)
						);
					} else {

						$this->db->update(
							$this->tb_prefix . "statistics_visit",
							array(
								'last_visit'	=>	$this->Current_Date(),
								'visit'			=>	$this->result->visit + $this->coefficient
							),
							array(
								'last_counter'	=>	$this->result->last_counter
							)
						);
					}
				}
			}
		}

		public function Visitors() {

			global $wp_version;

			// If we're a webcrawler or referral from ourselves, don't record the visitor.
			if( !$this->Check_Spiders() && !( $_SERVER['HTTP_USER_AGENT'] == "WordPress/" . $wp_version . "; " . get_home_url("/") || $_SERVER['HTTP_USER_AGENT'] == "WordPress/" . $wp_version . "; " . get_home_url() )  ) {

				$this->result = $this->db->get_row("SELECT * FROM {$this->tb_prefix}statistics_visitor WHERE <code>last_counter</code> = '{$this->Current_Date('Y-m-d')}' AND <code>ip</code> = '{$this->get_IP()}'");

				if( !$this->result ) {

					$agent = $this->get_UserAgent();

					$this->db->insert(
						$this->tb_prefix . "statistics_visitor",
						array(
							'last_counter'	=>	$this->Current_date('Y-m-d'),
							'referred'		=>	$this->get_Referred(true),
							'agent'			=>	$agent['browser'],
							'ip'			=>	$this->get_IP()
						)
					);
				}
			}
		}
	}

Closing topic.
