notice: Undefined index: HTTP_USER_AGENT

I have gk_sporter template and since i moved to a new host who have error reporting on i see sometimes these messages. I googled these and i found out that when some users or bots dont send correct "signals" to site or something the website doesnt know what version of browser to use and shows these messages. Unfortunately i cant find a solution... Any help out there?

Hi,

The fastest solution is disable notices in the php.ini file. We will add additional check for the HTTP_USER_AGENT variable in the next update.

Thanks for the quick reply but my web host insist that these errors cause high server load peaks and asks me to fix them. Any advice on this?

Thanks

Please open file /templates/gk_sporter/libs/gk.template.helper.php and line 363 replace :

Code: Select all

function mobile_device_detect () {
      require_once ('mobile_device_detect.php');
      //bypass special browser:
      $special = array('jigs', 'w3c ', 'w3c-', 'w3c_');      
      if (in_array(strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)), $special)) return false;
      return mobile_device_detect('iphone','android','opera','blackberry','palm','windows');
   }


with :

Code: Select all

function mobile_device_detect () {
      require_once ('mobile_device_detect.php');
      //bypass special browser:
      $special = array('jigs', 'w3c ', 'w3c-', 'w3c_');   
      if(isset($_SERVER['HTTP_USER_AGENT'])) {
         if (in_array(strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)), $special)) return false;
      }
      return mobile_device_detect('iphone','android','opera','blackberry','palm','windows');
   }

then open the second file (templates/gk_sporter/libs/mobile_device_detect.php) and in line 4 replace :

Code: Select all

$useragent=$_SERVER['HTTP_USER_AGENT'];

with :

Code: Select all

if(isset($_SERVER['HTTP_USER_AGENT'])) {
      $useragent=$_SERVER['HTTP_USER_AGENT'];
   } else {
      $useragent='chrome';
   }

It seems the problem solved after following your instructions.

Thank you very much!
