Note: I am sure there are other (perhaps even better) ways to get this to work, and I am open to your suggestions. Full php plugin file available here.

If you are one of the millions who use WordPress to power your site, you don’t have to sacrifice your Pluck comments. Using Pluck’s comments will keep your community interactions aggregated into one platform and surface in the users’ personas. You should avoid fragmenting your user generated content across multiple platforms.

Although Pluck does not have an official WP plugin, its not terribly hard to set up. For the sake of demonstration, I will call the plugin pluckplugin.

It is a good idea to save some settings so they can be changed later. The plugin stores the follwing data in the WordPress options table:

• Pluck Domain
• Shared Secret
• Cookie Name
• Whether or not to use Pluck’s comments

Implementation Steps:

• Get any saved options from the database.

$this->options = get_option("pluckplugin_settings");

• Inject the appropriate Pluck libraries into the header using “wp_head”.

add_action("wp_head", array($this,"pluckplugin_head_includes"));

function pluckplugin_head_includes(){
   global $wpdb;
   $PluckSavedData = array();
   if (get_option ("pluckplugin_settings")){
      $PluckSavedData = get_option("pluckplugin_settings");
   }
}

• Drop the ‘at’ cookie when users login to WordPress (if desired) using “wp_login”.

add_action("wp_login", array($this,"pluckplugin_drop_at_cookie"), 10, 2);

function pluckplugin_drop_at_cookie($user_login, $user){
   global $wpdb;
   $PluckSavedData = array();
   if (get_option ("pluckplugin_settings")){
      $PluckSavedData = get_option("pluckplugin_settings");

      if (isset($PluckSavedData['PluckDomain']) && isset($PluckSavedData['PluckSharedSecret'])){
         $userId = $user- />data- />ID;
         $userName = $user- />data- />user_nicename;
         $userTime = "1";
         $userEmail = $user- />data- />user_email;
         $PwKey = $PluckSavedData['PluckSharedSecret'];

         //Get Domain from PluckDomain
         $DomainParts = explode(".",$PluckSavedData['PluckDomain']);
         $CookieDomain = ".". $DomainParts[1] .".". $DomainParts[2] ."";

         $Pieces = "$userId.$userName.$userTime.$userEmail.$PwKey";
         $secret_hash = md5($Pieces);
         $CookieString = "u=$userId&a=$userName&e=$userEmail&t=$userTime&h=$secret_hash";

         //Check to see if using 'at' cookie name
         $CookieName = "at";
         if (isset($PluckSavedData['PluckCookieName'])){
            $CookieName = $PluckSavedData['PluckCookieName'];
         }

         $expire=time()+60*60*24*30;
         setcookie($CookieName, $CookieString, $expire, "/", $CookieDomain);
      }
   }
}

• Create the admin section using “admin_menu”.

add_action("admin_menu", array($this,"pluckplugin_admin_actions"));

• Once everything is in place, you need to call a function which checks to see if the comments are open, then checks to see if Pluck’s comments are on, then renders everything appropriately.
