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/

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
