Settings API Multiple Checkbox in General Settings

An option is a meta information saved in the database as a string. An array is a memory specific variable that has its own characteristics. But to every problem there is a workaround: $myoption = json_encode($the_array(); add_option(‘myoption’, $myoption, ”, ‘yes’); Now to fetch it: $myoption = json_decode(get_option(‘myoption’)); Voila.

Use http://codex.wordpress.org/Settings_API to add new setting to existed group “general”: add_action( ‘admin_init’, ‘register_my_setting’ ); function register_my_setting() { add_settings_field(‘foo’, ‘Foo settings’, ‘foo_function’, ‘general’, ‘default’, array(‘label_for’ => ‘foo’)); register_setting(‘general’, ‘foo’, ‘foo value’); } function foo_function() { echo ‘<input name=”foo” id=”foo” value=”” class=”regular-text ltr”>’; } You must modify function to validate input and to show saved value.
