Editing WordPress Video Galleries (section)

==== Gotchas: Shadowbox JS having no effect ====

'''Symptom:''' For some reason after an upgrade to '''Wordpress 3.6''', '''YouTube SimpleGallery 2.0.6''', and '''Shadowbox JS 3.0.3.10.2''', the call to `Shadowbox.init()` was throwing an error: `'Shadowbox is not defined.'`

'''Effect:''' Clicking a video thumbnail in a '''YouTube SimpleGallery''' gallery will redirect to the video's page on YouTube.com or Vimeo.com instead of playing the video in a lightbox over the current page.

'''Cause:''' Again, after this particular upgrade, the '''Shadowbox''' library was being added to the footer. This is done explicitly by the plugin, and it causes the '''Shadowbox''' library to be defined after the call to `Shadowbox.init()`.

'''Solution:''' Hacked the '''Shadowbox JS''' plugin to include the '''Shadowbox''' library in the template header.

Update `wp_register_scirpt()` call in the `ShadowboxFrontend::scripts()` routine found in `[PLUGINS_DIR]/shadowbox-js/inc/frontend.php`:

<syntaxhighlight lang="php" line start="168">
// wp_register_script ( 'shadowbox' , apply_filters ( 'shadowbox-js' , $shadowbox ) , $dependency , $this->sbversion , true );
/* change in_footer option of wp_register_script() to 'false' */
wp_register_script ( 'shadowbox' , apply_filters ( 'shadowbox-js' , $shadowbox ) , $dependency , $this->sbversion , false );
</syntaxhighlight>
