[Plugin: wordTube] myplaylist just for audio

Just in case you didn’t notice the comments in the code, my update above adds one new tag.

It uses whatever the MP3 settings are in the wordTube settings.

Place a [MYMUSICPLAYLIST=x] tag into your page.

The specified playlist should of course only contain MP3’s, but if it contains videos then you either just get the audio, or a thin strip of video played (if you have the equaliser switched on).

Thanks Alex, I’m taking a look through v2 now. In the meantime, here’s an update to my above post for anyone using v1.6.

I was having difficulty getting the player controls to show, which this version fixes (by removing the IE fixes!). This version also changes the mode of the shortcodes slightly (from my original version above) – they now IGNORE the mp3 settings on the wordTube admin page (which now really only apply to the MEDIA shortcode).

This version makes available two shortcodes as I wanted to give my users the ability to specify whether to show the equaliser or not, rather than there being a global setting. See the notes in the code for details of the shortcodes.

I’ve tested this successfully on:

Firefox v 3.0.1 on Ubuntu Linux
IE 6.0.29 on Win XP_SP2 – Flash player 9,0,47,0
IE 7.0.5730 on Win XP_SP2 – Flash player 9,0,47,0

NOTE: I have NOT tested the Excerting or RSS side of this (as I don’t use that), so if that’s important to you then please check it all works!

Music Playlist Update 

Ver: 13-Aug-2008
This update author: Dave H
This update:
            Modifies the: CheckForTags(), searchvideo(), excerpt_searchblank(),
                  ReturnPlaylist() functions.

                  NOTE: I have commented out the IE fix for 'width' and 'height'
                        in returnMedia() and returnPlaylist() as they were messing up
                        the player in IE 6 for me. Works good for me now.

            Adds a new function: ReturnMusicPlaylist() to process the new tags.

New tags created: [MYMUSICPLAYLIST=x]
                     Displays a music player with playlist.
                     This tag ignores the wordTube 'mp3 display' setting.

                  [MYEQMUSICPLAYLIST=x]
                     Displays a music player with playlist and an equaliser.
                     This tag ignores the wordTube 'mp3 display' setting.
