Where Should I Put a Custom DetectXXX() Block?

Posted on by Anthony Hand

Wow! Where has the year gone?!? How can it be September already? It’s been a beautiful year and it’s gone by so quickly…

An MIT alum and entrepreneur wrote me recently with a good question. While building out and testing a new e-commerce site, they encountered a very strange useragent and wanted to build a custom detection method to catch it. He wasn’t sure the best way to integrate such a custom detection feature into the codebase. This is what I might recommend.

Let’s say you were using PHP. To keep the code fairly modular and easy to maintain over time, I might recommend creating a custom DetectXXX() method that you could easily copy forward into new MobileESP versions. If you wanted to check automatically every time, then put a call to it in the DetectMobileQuick() method. For example:
   function DetectMobileQuick()
   {
      //Keep all the stuff at the top unchanged...

      //Finally, call your custom method
      if ($this->DetectCustomAgents() == $this->true)
         return $this->true;
      else
         return $this->false;
   }

   function DetectCustomAgents()
   {
      if (stripos($this->useragent, "silly_that_i_have_to_do_this") > -1)
         return $this->true;
      else
         return $this->false;
   }
Good luck on your new venture, Bill!
