Plugins

The presenters mentioned some useful plugins when managing custom fields and creating custom metaboxes. There are many more available in the WordPress Plugin Repository.

• Types: Creates Custom Post Types, Custom Taxonomies, & Custom Fields/Metaboxes. Used by Sallie on the BACN website.
• Meta Box by Deluxe Blog Tips provides the JavaScript necessary for things like date-pickers and time selectors. You still need to code your actual metaboxes, but it speeds up development. Tutorials available.
• Advanced Custom Fields. Similar to Meta Box, but also lets you create your metaboxes through the WordPress admin.
• WP Alchemy MetaBox PHP Class. Not precisely a plugin, though you can make it into one or bundle it into one if you want.
• Custom Field Bulk Editor. Very handy if you decide halfway through your project that you want to rename one of your custom fields, or remove it.
