WordPress 2.7 requires that plugins explicitly white list their options using a couple new functions. WordPress MU has required this security measure for a while, and it’s nice to see an evolved form of it brought to the core code. [Migrating Plugins and Themes to 2.7][1] article in the codex offers some guidance, but here’s how it works:
First, register each option for your plugin during the admin_init action:
| ``` function myplugin_admin_init(){ register_setting( 'my-options-group', 'my-option-name-1', 'absint' ); register_setting( 'my-options-group', 'my-option-name-2', 'wp_filter_nohtml_kses' ); } add_action( 'admin_init', 'myplugin_admin_init' ); ``` |
In the example above, the value for my-option-name-1 will be filtered by absint before being saved to the options table. my-option-name-2 will be stripped of any HTML by wp_filter_nohtml_kses.
Then build a form like this prototype:

Perhaps worse, the problems are blamed on essential breakdowns in the project management: “We have changed the release model so that instead of focusing on quality and features our release is now defined by timeliness and features. Quality is not regarded to be that important.” Still, people are finding inspiration in OurDelta and Drizzle. Competition from those braches/forks and criticism from the community are sure to help re-align the MySQL core, or provide a reasonable alternative if Sun/MySQL can’t deliver. In the meanwhile, the High Availability MySQL blog is worth following.
