我刚刚建立了一个测试环境来测试我的新Wordpress网站。我没有迁移数据库；我再次进行了自己的安装，并将我的主题（这是一个简单的主题）移植到我的新实例。除了我正在使用的一种自定义帖子类型外，其他一切都很好。

以下是来自的相关代码functions.php:

function createCommunityPostType() {
    $args = array(
            \'public\' => true,
            \'label\' => \'Community\',
            \'capability_type\' => \'community\',
                \'capabilities\' => array(
                                \'edit_post\' => \'edit_community\',
                                \'edit_private_posts\' => \'edit_private_communities\',
                                \'edit_published_posts\' => \'edit_published_communities\',
                                \'edit_posts\' => \'edit_communities\',
                                \'edit_others_posts\' => \'edit_others_communities\',

                                \'delete_post\' => \'delete_community\',
                                \'delete_posts\' => \'delete_communities\',
                                \'delete_others_posts\' => \'delete_others_communities\',
                                \'delete_private_posts\' => \'delete_private_communities\',
                                \'delete_published_posts\' => \'delete_published_communities\',

                                \'read_private_posts\' => \'read_private_communities\',
                                \'read_post\' => \'read_community\',
                                \'publish_posts\' => \'publish_communities\'
                ),
                \'map_meta_cap\' => true,
                \'has_archive\' => true
    );
    register_post_type(\'community\', $args );
}
add_action(\'init\', \'createCommunityPostType\');

我的自定义帖子类型没有显示在菜单中，我可以看到这些功能不存在（我正在使用members插件使其更加可见）。

我知道代码正在执行，因为我添加了一些print 调用之前和之后的语句register_post_type. 打印语句是HTML响应的一部分。

我不明白为什么这种帖子不起作用。我有其他方法functions.php 处理样式表、脚本、菜单和侧栏的一些替代等。这些都很好用。

Edit:

我改为使用默认功能，但菜单选项仍然没有出现：

function createCommunityPostType() {
    $args = array(
            \'public\' => true,
            \'label\' => \'Community\',
            \'capability_type\' => \'community\',
                \'capabilities\' => array(
                                \'edit_post\' => \'edit_posts\',
                                \'edit_private_posts\' => \'edit_posts\',
                                \'edit_published_posts\' => \'edit_posts\',
                                \'edit_posts\' => \'edit_posts\',
                                \'edit_others_posts\' => \'edit_posts\',

                                \'delete_post\' => \'delete_posts\',
                                \'delete_posts\' => \'delete_posts\',
                                \'delete_others_posts\' => \'delete_posts\',
                                \'delete_private_posts\' => \'delete_posts\',
                                \'delete_published_posts\' => \'delete_posts\',

                                \'read_private_posts\' => \'read\',
                                \'read_post\' => \'read\',
                                \'publish_posts\' => \'publish_posts\'
                ),
            \'map_meta_cap\' => true,
                \'has_archive\' => true
    );
    register_post_type(\'community\', $args );
}
add_action(\'init\', \'createCommunityPostType\');

然而，我切换到使用Wordpress中一些非常基本的示例代码，出现了自定义帖子类型（CPT）：

function codex_custom_init() {
    $args = array( \'public\' => true, \'label\' => \'Books\' );
    register_post_type( \'book\', $args );
}
add_action( \'init\', \'codex_custom_init\' );

\'capability_type\' => \'community\'

\'capabilities\' => array(
    \'edit_post\' => \'edit_community\',
    \'edit_private_posts\' => \'edit_private_communities\',
    \'edit_published_posts\' => \'edit_published_communities\',
    \'edit_posts\' => \'edit_communities\',
    \'edit_others_posts\' => \'edit_others_communities\',

    \'delete_post\' => \'delete_community\',
    \'delete_posts\' => \'delete_communities\',
    \'delete_others_posts\' => \'delete_others_communities\',
    \'delete_private_posts\' => \'delete_private_communities\',
    \'delete_published_posts\' => \'delete_published_communities\',

    \'read_private_posts\' => \'read_private_communities\',
    \'read_post\' => \'read_community\',
    \'publish_posts\' => \'publish_communities\'
),

\'capability_type\' => array( \'community\', \'communities\' )
