我在我的一个网站上使用以下自定义帖子类型：

function careers_post_type() {

    $labels = array(
        \'name\'                => _x( \'Careers\', \'Post Type General Name\', \'text_domain\' ),
        \'singular_name\'       => _x( \'Career\', \'Post Type Singular Name\', \'text_domain\' ),
        \'menu_name\'           => __( \'Careers\', \'text_domain\' ),
        \'parent_item_colon\'   => __( \'Parent career:\', \'text_domain\' ),
        \'all_items\'           => __( \'All careers\', \'text_domain\' ),
        \'view_item\'           => __( \'View career\', \'text_domain\' ),
        \'add_new_item\'        => __( \'Add New career\', \'text_domain\' ),
        \'add_new\'             => __( \'New career\', \'text_domain\' ),
        \'edit_item\'           => __( \'Edit career\', \'text_domain\' ),
        \'update_item\'         => __( \'Update career\', \'text_domain\' ),
        \'search_items\'        => __( \'Search careers\', \'text_domain\' ),
        \'not_found\'           => __( \'No careers found\', \'text_domain\' ),
        \'not_found_in_trash\'  => __( \'No careers found in Trash\', \'text_domain\' ),
    );
    $args = array(
        \'label\'               => __( \'career\', \'text_domain\' ),
        \'description\'         => __( \'career information pages\', \'text_domain\' ),
        \'labels\'              => $labels,
        \'supports\'            => array( ),
        \'taxonomies\'          => array( ),
        \'hierarchical\'        => false,
        \'public\'              => true,
        \'show_ui\'             => true,
        \'show_in_menu\'        => true,
        \'show_in_nav_menus\'   => true,
        \'show_in_admin_bar\'   => true,
        \'menu_position\'       => 5,
        \'can_export\'          => true,
        \'has_archive\'         => true,
        \'exclude_from_search\' => false,
        \'publicly_queryable\'  => true,
        \'capability_type\' => \'post\',
    );
    register_post_type( \'career\', $args );

}

吸盘工作得很好。但是，我想为其添加一个自定义功能。我使用了本教程：http://justintadlock.com/archives/2010/07/10/meta-capabilities-for-custom-post-types 一旦我将代码设置为这样，它就会停止工作：

// Register Custom Post Type
function careers_post_type() {

    $labels = array(
        \'name\'                => _x( \'Careers\', \'Post Type General Name\', \'text_domain\' ),
        \'singular_name\'       => _x( \'Career\', \'Post Type Singular Name\', \'text_domain\' ),
        \'menu_name\'           => __( \'Careers\', \'text_domain\' ),
        \'parent_item_colon\'   => __( \'Parent career:\', \'text_domain\' ),
        \'all_items\'           => __( \'All careers\', \'text_domain\' ),
        \'view_item\'           => __( \'View career\', \'text_domain\' ),
        \'add_new_item\'        => __( \'Add New career\', \'text_domain\' ),
        \'add_new\'             => __( \'New career\', \'text_domain\' ),
        \'edit_item\'           => __( \'Edit career\', \'text_domain\' ),
        \'update_item\'         => __( \'Update career\', \'text_domain\' ),
        \'search_items\'        => __( \'Search careers\', \'text_domain\' ),
        \'not_found\'           => __( \'No careers found\', \'text_domain\' ),
        \'not_found_in_trash\'  => __( \'No careers found in Trash\', \'text_domain\' ),
    );
    $args = array(
        \'label\'               => __( \'career\', \'text_domain\' ),
        \'description\'         => __( \'career information pages\', \'text_domain\' ),
        \'labels\'              => $labels,
        \'supports\'            => array( ),
        \'taxonomies\'          => array( ),
        \'hierarchical\'        => false,
        \'public\'              => true,
        \'show_ui\'             => true,
        \'show_in_menu\'        => true,
        \'show_in_nav_menus\'   => true,
        \'show_in_admin_bar\'   => true,
        \'menu_position\'       => 5,
        \'can_export\'          => true,
        \'has_archive\'         => true,
        \'exclude_from_search\' => false,
        \'publicly_queryable\'  => true,
        \'capability_type\' => \'career_editor\',
        \'capabilities\' => array(
            \'publish_posts\' => \'publish_career\',
            \'edit_posts\' => \'edit_career\',
            \'edit_others_posts\' => \'edit_others_career\',
            \'delete_posts\' => \'delete_career\',
            \'delete_others_posts\' => \'delete_others_career\',
            \'read_private_posts\' => \'read_private_career\',
            \'edit_post\' => \'edit_career\',
            \'delete_post\' => \'delete_career\',
            \'read_post\' => \'read_career\',
        ),
    );
    register_post_type( \'career\', $args );

}

我甚至尝试过去掉功能数组，但内容类型仍然消失了。我做错了什么？

....
\'capability_type\' => \'career\'
....

    add_role(\'career_editor\', \'Carreer Editor\', array (
        \'publish_career\'        => true,
        \'edit_career\'           => true,
        \'edit_others_careerr\'   => true,
        \'delete_career\'         => true,
        \'delete_others_career\'  => true,
        \'read_career\'           => true,
        \'edit_career\'           => true,
        \'delete_career\'         => true,
        \'read_career\'           => true,
        \'read_private_carreer\'  => true,
        \'read\'                  => true,
   ));
