Question

这是我的自定义帖子类型代码，我想给订阅者用户添加、编辑、删除权限。

如何在 wordpress 中允许订阅者用户自定义帖子类型（添加、编辑、删除）。请帮助我提前谢谢。

add_action( 'init', 'realestate_init' );
        function realestate_init() {
        $labels = array(
            'name'               => _x( 'Realestates', 'post type general name', 'your-plugin-textdomain' ),
            'singular_name'      => _x( 'Realestate', 'post type singular name', 'your-plugin-textdomain' ),
            'menu_name'          => _x( 'Realestates', 'admin menu', 'your-plugin-textdomain' ),
            'name_admin_bar'     => _x( 'Realestate', 'add new on admin bar', 'your-plugin-textdomain' ),
            'add_new'            => _x( 'Add New', 'realestate', 'your-plugin-textdomain' ),
            'add_new_item'       => __( 'Add New Realestate', 'your-plugin-textdomain' ),
            'new_item'           => __( 'New Realestate', 'your-plugin-textdomain' ),
            'edit_item'          => __( 'Edit Realestate', 'your-plugin-textdomain' ),
            'view_item'          => __( 'View Realestate', 'your-plugin-textdomain' ),
            'all_items'          => __( 'All Realestates', 'your-plugin-textdomain' ),
            'search_items'       => __( 'Search Realestates', 'your-plugin-textdomain' ),
            'parent_item_colon'  => __( 'Parent Realestates:', 'your-plugin-textdomain' ),
            'not_found'          => __( 'No realestates found.', 'your-plugin-textdomain' ),
            'not_found_in_trash' => __( 'No realestates found in Trash.', 'your-plugin-textdomain' )
        );
        $args = array(
            'labels'             => $labels,
            'description'        => __( 'Description.', 'your-plugin-textdomain' ),
            'public'             => true,
            'publicly_queryable' => true,
            'show_ui'            => true,
            'show_in_menu'       => true,
            'query_var'          => true,
            'rewrite'            => array( 'slug' => 'realestate' ),
            'capability_type'    => 'post',
            'has_archive'        => true,
            'hierarchical'       => false,
            'menu_position'      => null,
            'supports'           => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' )
        );
        register_post_type( 'realestate', $args );
    }
    // End register custom post type

为了简化这个过程，让我们使用一个角色并为其分配所有所需的功能来管理（添加、编辑、发布、删除）我们的自定义帖子类型。

function add_custom_caps() {
    // gets the subscriber role
    $role = get_role( 'subscriber' );

    // This only works, because it accesses the class instance.
    // would allow the subscriber to edit others' posts for current theme only
     $role->add_cap( 'read' );
     $role->add_cap( 'read_post');
     $role->add_cap( 'read_private_post' );
     $role->add_cap( 'edit_post' );
     $role->add_cap( 'edit_others_post' );
     $role->add_cap( 'edit_published_post' );
     $role->add_cap( 'publish_post' );
     $role->add_cap( 'delete_others_post' );
     $role->add_cap( 'delete_private_post' );
     $role->add_cap( 'delete_published_post' );
}
add_action( 'admin_init', 'add_custom_caps');

这段代码相当简单。我们有一个当前角色的WP_Role 对象，然后使用WordPress add_cap() 函数将我们的新_post 功能添加到所述角色。请参阅get_role() function on the codex 以更好地了解可用的功能。
