CR-Post2PingFM Plugin Tweaked for WordPress MU

Although this is not strictly related to Second Life itself, I need some place to put a tweaked version of Arief Bayu Purwanto’s CR Post2PingFM plugin, which required some tweaking to work well with WordPress MU.

The problem has to do with setting and reading options properly in a multiblog environment. WordPress and WordPress MU handle this differently, thus the original, untweaked plugin didn’t work properly.

Thanks to Marcus Cudd for helping me to debug it!

You have to enclose it in the usual PHP tags, which this code plugin sadly eats up.

Warning: Beachbum noticed quite correctly that the single quotes in the code get unfortunately converted by WordPress into “typographical quotes”, so you have to be extra-careful when copying & pasting this! Thanks for the tip, Beachbum
