Subject: Need help finishing up a Google Analytics plugin
Ok, I read in the docs some of the plugin hooks, then hacked the custompage.php plugin to come up with something I think is 95% done.  It doesn't actually do anything right now though.  :)  Here's what I have, maybe you can help me make it work.  Messy code follows:
  1. <?php
  2. /*
  3. Name:   Google Analytics UNB Plugin
  4. Purpose:    This plugin allows you to easily insert Google Analytics javascript code into your UNB forum.
  5.         See http://www.google.com/analytics for more details on why you would want to do this.
  6. Version:    0.1
  7. Author: Hal Rottenberg <hal@halr9000.com>   
  8. */
  9. if (!defined('UNB_RUNNING')) die('Not a UNB environment in ' . basename(__FILE__));
  10.  
  11. // Define plug-in meta-data
  12. UnbPluginMeta('Google Analytics');
  13. UnbPluginMeta('Hal Rottenberg <hal@halr9000.com>', 'author');
  14. UnbPluginMeta('en', 'lang');
  15. UnbPluginMeta('unb.stable.1.6.rc.3 unb.stable.1.6.99', 'version');
  16. UnbPluginMeta('unb.devel.20051014', 'version');
  17.  
  18. if (!UnbPluginEnabled()) return;
  19.  
  20. function UnbHookInsertGA()
  21. {
  22.  $ua = "foo"; // Insert yours here.  Someone please code a form for me?
  23.  $GAscript = "<script src=\"http://www.google-analytics.com/urchin.js\" type=\"text/javascript\"></script><script type=\"text/javascript\">_uacct = \"$ua\";urchinTracker();</script>";
  24.  return $GAscript;
  25. }
  26.  
  27. // Register hook functions
  28. UnbRegisterHook('page.htmlhead', 'UnbHookInsertGA');
  29.  
  30. ?>

Check out the plug-in documentation. It has a list of all hooks with the data passed to the handler function. You need to access this data because you must pass your changes back in them. The return value must be true, if it's false, the hook chain will stop after this function. If it's not boolean, behaviour is undefined. So your code looks like follows:

  1. //...
  2. function UnbHookInsertGA($str)
  3. {
  4.  $ua = "foo"; // Insert yours here.  Someone please code a form for me?
  5.  $GAscript = "<script src=\"http://www.google-analytics.com/urchin.js\" type=\"text/javascript\"></script><script type=\"text/javascript\">_uacct = \"$ua\";urchinTracker();</script>";
  6.  $str = $GAscript;
  7.  return true;
  8. }
  9. //...

That didn't seem to make any difference.  Hmm.  No errors, but no script in <head> either.
