New Widgets API

WP_Widget is a class that abstracts away much of the complexity involved in writing a widget, especially multi-widgets.

  • Basically, you extend WP_Widget with your own class that provides a constructor and three methods — widget(), form(), and update().
    • widget() – outputs the actual content of the widget.
    • update() – processes options to be saved.
    • form() – outputs the options form.
  • A widget is registered by passing the name of the widget class to register_widget().
  • All widgets written with WP_Widget are multiple instance capable.
  • Options
    • Options for old single-instance widgets ported to WP_Widget will be upgraded to the new multi-option storage format, which is simply a multi-dimensional array keyed by instance ID.
    • Options for widgets using the old multi-instance pattern should work as is.
    • If your widget has custom option storage needs, you can provide your own get_settings() and save_settings() methods.
  • The WP_Widget source can be viewed here (read the phpdoc for moreinfo on usage): http://core.trac.wordpress.org/browser/trunk/wp-includes/widgets.php
  • You can see examples of how to use it here: http://core.trac.wordpress.org/browser/trunk/wp-includes/default-widgets.php
  • If you author any widgets, try porting them to WP_Widget and give your feedback on what can be improved an Trac Ticket 8441.
  • Props to the MultiWidget class, on which WP_Widget is based: http://blog.firetree.net/2008/11/30/wordpress-multi-widget/
  • The above extracted from Ryan Boren’s wp-hackers post.

See also Widgets API.

Menu reordering via plugin
  • Example plugin demonstrates menus with Dashboard, Posts, and Comments in the first menu group. The remaining menus follow in their usual order.
  • When filtering the order array, any menus that are not mentioned in the array will be sorted after ones that are mentioned.
  • Unmentioned menus are sorted in their usual order, relative to other unmentioned menus.
  • Information extracted from Ryan Boren’s comments on Trac Ticket 9652

Features That Didn’t Make it into Version 2.8

These features didn’t make it into Version 2.8 (or Version 2.7).

  • oEmbed support, tied in with shortcodes
  • Better UI for post revisions, maybe an optional field to say what changed in a version
  • OAuth support
  • GeoData for posts, comments, attachments, etc.
  • Template tags to do everything the custom gallery on ma.tt does
  • Menu editor
  • Unbalanced tags across more and nextpage tags (Ticket 6297)
  • Sitemaps by default
  • Refresh of the importers (LiveJournal was refreshed)
  • Gallery post_type
