WPMu and Google Blog Search Pinging Service

How to configure WordPress Mu with Google Blog Search Pinging Service

By default, WordPress Mu pings Ping-o-Matic only and it is no longer possible to add new sites with the wp-admin interface: “Sites get pinged by default. That option [to add other Pinging Services] was removed to simplify the interface.” (donncha)

Thus, adding a new Pinging Service (in this case Google Blog Search Pinging Service) requires an update to the *_options table for each blog. Richard Pendergast clearly shows how to do this over on the DevLounge.

For example,

mysql> SELECT option_value
FROM [secret]_2_options
WHERE option_name = "ping_sites";
+----------------------------+
| option_value |
+----------------------------+
| http://rpc.pingomatic.com/ |
+----------------------------+
1 row in set (0.00 sec)
mysql> UPDATE [secret]_2_options
SET option_value = "http://rpc.pingomatic.com/\nhttp://blogsearch.google.com/ping/RPC2/"
WHERE option_name = "ping_sites";
Query OK, 1 row affected (0.00 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> SELCT option_value FROM [secret]_2_options WHERE option_name = "ping_sites";
+-------------------------------------------------------------------+
| option_value |
+-------------------------------------------------------------------+
| http://rpc.pingomatic.com/
http://blogsearch.google.com/ping/RPC2/ |
+-------------------------------------------------------------------+
