 //完整的示例是这样，但是除了Plugin Name其他都不是必须的

//启用插件时的处理
function pluginprefix_setup_post_type() {

    register_post_type( 'book', ['public' => 'true'] );

    flush_rewrite_rules();
}

//停用插件时的处理
function pluginprefix_deactivation() {
    // unregister the post type, so the rules are no longer in memory
    unregister_post_type( 'book' );
    // clear the permalinks to remove our post type's rules from the database
    flush_rewrite_rules();
}

// if uninstall.php is not called by WordPress, die
// 防止误操作直接访问该文件
if (!defined('WP_UNINSTALL_PLUGIN')) {
    die;
}
 
$option_name = 'wporg_option';
 
 //这两行是删除插件的一些附加配置，后边我会继续说这个
delete_option($option_name);
 
// for site options in Multisite
delete_site_option($option_name);
 
// drop a custom database table
global $wpdb;
$wpdb->query("DROP TABLE IF EXISTS {$wpdb->prefix}mytable");
