Random thoughts on art, technology, stuff, and occasionally Real Estate: Real Coders Copy and Paste

A couple months ago, I created some WordPress Mu (Multiple User) communities. 

( http://activerain.com/blogsview/851850/Installing-WordPress-MU-on-GoDaddy-Yes-It-Can-Be-Done

http://activerain.com/blogsview/888615/I-declare-it-is-done-enough-for-now-at-any-rate  )

Mu is a slightly different animal than stand-alone WordPress.org.  In fact, in several ways, it lacks some of the functionality of the stand-alone version.  Why? Because the developers of Mu figured there were security risks inherit in a public, multi-blog community .... and so some basic, simple functions such as embedding a video, or using iframes are disabled.

And enabling those simple functions is perhaps a little trickier than necessary.

1.  First attempt at a solution:  The Unfiltered MU plugin.  Unfiltered MU works great, when it works, but is temperamental and does not every time.

2.  Back to the Mu forums, its sounding as if I may need to hack the kses.php file.  Hmmmm.

http://mu.wordpress.org/forums/topic.php?id=7851

3.  Then I find this plugin http://wpmudev.org/project/Allow-Embedded-Videos , but the writer of the plugin, Stuart Maxwell, only coded it to include embedded videos.  He says "If you look at the source code of the plugin you'll see how easy it is to add additional tags so that you could modify it to allow iframes, forms or whatever else you want."

4.  Okayfine.  So now I need to copy the iframe code from taiwanese's post here http://mu.wordpress.org/forums/topic.php?id=7851  and paste it into Stuart Maxwell's code.

Here's the final product which now resides in the plugin folder of one of my Mu communities:

Please feel free to copy it to a text file, and upload to your own Mu community. 

File name should be  524507081_az-kses     (no dot anything at the end) 

Upload the file  to your mu-plugins folder

At least I have now made it easier for the next person who comes along.  :-)
