How to track the activities of visitor

Here in this post, you will learn how to track the activities of the visitor in your website. By tracking activities here, I mean to say, we will want to store information about from which link the visitor came, whats the IP address of the visitor, did he come by clicking a link on any other website or did he came directly to our page. All such information can be tracked. Information we would like to track are:


  • IP of the visitor: $_SERVER['REMOTE_ADDR']
  • Requested URI: $_SERVER['REQUEST_URI']
  • Current Website: $_SERVER['HTTP_HOST']
  • Current URL: curlPageURL()
     public function curPageURL() {
            $pageURL = 'http';
            if ($_SERVER["HTTPS"] == "on") {$pageURL .= "s";}
            $pageURL .= "://";
            if ($_SERVER["SERVER_PORT"] != "80") {
                $pageURL .= $_SERVER["SERVER_NAME"].":".$_SERVER["SERVER_PORT"].$_SERVER["REQUEST_URI"];
            } else {
                $pageURL .= $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"];
            }
            return $pageURL;
        }

  • Browser: detect($_SERVER['HTTP_USER_AGENT'])
public static function detect($userAgent)     {        strtolower($userAgent);        if (preg_match('/opera/', $userAgent)) {            $name = 'opera';        }        elseif (preg_match('/chrome/', $userAgent)) {            $name = 'chrome';            }        elseif (preg_match('/webkit/', $userAgent)) {            $name = 'safari';        }        elseif (preg_match('/msie/', $userAgent)) {            $name = 'msie';        }        elseif (preg_match('/mozilla/', $userAgent) && !preg_match('/compatible/', $userAgent)) {            $name = 'mozilla';        }        else {            $name = 'unrecognized';        }        // version?        if (preg_match('/.+(?:rv|it|ra|ie)[\/: ]([\d.]+)/', $userAgent, $matches)) {            $version = $matches[1];        }        else {            $version = 'unknown';        }        // platform?        if (preg_match('/linux/', $userAgent)) {            $platform = 'linux';        }        elseif (preg_match('/macintosh|mac os x/', $userAgent)) {            $platform = 'mac';        }        elseif (preg_match('/windows|win32/', $userAgent)) {            $platform = 'windows';        }        else {            $platform = 'unrecognized';        }        return array(            'name'      => $name,            'version'   => $version,            'platform'  => $platform,            'userAgent' => $userAgent        );    }
Now that we can get these information we can store these information to database for each page load. This will make our Activity Tracker for our website.

Automate file upload in Selenium IDE

Image
Selenium IDE is an integrated development environment for Selenium tests. It records your interactions with websites to help you generate and maintain site automation, tests, and remove the need to manually step through repetitive tasks. Selenium IDE can be installed in Google Chrome from  here . For Firefox visit this  link . File upload in Selenium IDE cannot be automated simply by recording from the IDE. Because when we select the file input field, the dialog that opens up is a system window which cannot be controlled by Selenium IDE. Therefore, clicking the input file field to select a file will not work. Also the selected file path is changed to C:\fakepath\filename.extension. So to fix this issue, we need to configure the browser to support file upload and then instead of clicking the input field we set the file using ‘type’ selenium command which is shown below. First, to support file upload in Selenium IDE, configure your browser to support file upload: Visit ‘...
