New 3.6 Audio/Video Shortcodes

Removing lines 877-888 of the wp_audio_shortcode function and 995-1006 of wp_video shortcode (in wp-includes/media.php) seems to solve the problem.

The problem seems to be that the $audios variable is just an empty array because if you don’t have any audio files attached to that post/page then no audio shortcodes will display, same for video. That is, if nothing is attached then get_attached_audio/video fails and it breaks the entire shortcode.

That does work (if you do it via the Media tab and ‘Add New’).

If you click ‘Add Media’ on a new post, go to ‘Upload Files’, upload a file and insert it into the post, that also works. However, if you try to attach that same uploaded video to another post or a page then it doesn’t – unless you then upload another video to that post/page (but don’t necessarily have to insert it, just so it has an attached video).

That is to say, if you have a post full of video shortcodes that were uploaded on other posts then they won’t show up, unless you attach a video to the post with all the video shortcodes.

(I should note that the shortcodes do get inserted. They just don’t display.)

Originally, I uploaded a video while in a post to via the ‘Add Media’ button to try out new shortcodes (thereby attaching that video to the post). Then when I tried inserting that same video later (even by just copying and pasting the shortcode) into another post it failed to display. If you upload a video via ‘Add New Media’ (under the Media menu) or presumably link to an external link then it works fine (like you’re trying).

The problem is that if the video/audio is attached to another post (that is, was uploaded whilst in another post/page to the one you’re trying to add it to) then it doesn’t display on the post/page — unless you then attach another video/audio file to that post/page.
