功能和自定义帖子类型

我有一个自定义帖子类型，我想限制对某些角色的访问，但是，我已经使用该自定义帖子类型添加了内容，现在必须对其进行限制。capability_type是“ post”

'capability_type' => 'post'

但是，当内容显示在后端时，哪个很好，但是现在，一旦添加任何功能，内容就会从后端消失？

我尝试自定义功能类型以包括复数定义来构造自己的功能类型，但是一旦删除或更改功能类型，它就消失了！

完整代码：

add_action( 'init', 'register_cpt_gallery' );

function register_cpt_gallery() {
$labels = array( 
    'name' => _x( 'Galleries', 'gallery' ),
    'singular_name' => _x( 'Gallery', 'gallery' ),
    'add_new' => _x( 'Add New', 'gallery' ),
    'add_new_item' => _x( 'Add New Gallery', 'gallery' ),
    'edit_item' => _x( 'Edit Gallery', 'gallery' ),
    'new_item' => _x( 'New Gallery', 'gallery' ),
    'view_item' => _x( 'View Gallery', 'gallery' ),
    'search_items' => _x( 'Search Galleries', 'gallery' ),
    'not_found' => _x( 'No galleries found', 'gallery' ),
    'not_found_in_trash' => _x( 'No galleries found in Trash', 'gallery' ),
    'parent_item_colon' => _x( 'Parent Gallery:', 'gallery' ),
    'menu_name' => _x( 'Galleries', 'gallery' ),
);

$args = array( 
    'labels' => $labels,
    'hierarchical' => true,
    'description' => 'Image galleries for teachers classes',
    'supports' => array( 'title', 'editor', 'author'),

    'public' => true,
    'show_ui' => true,
    'show_in_menu' => true,

    'menu_icon' => get_bloginfo('template_url') . '/images/imagegallery.png',
    'show_in_nav_menus' => true,
    'publicly_queryable' => true,
    'exclude_from_search' => false,
    'has_archive' => true,
    'query_var' => true,
    'can_export' => true,
    'rewrite' => true,
    'capability_type' => 'post',
    'capabilities' => array(
        'edit_post' => 'edit_gallery',
        'edit_posts' => 'edit_galleries',
        'edit_others_posts' => 'edit_other_galleries',
        'publish_posts' => 'publish_galleries',
        'read_post' => 'read_gallery',
        'read_private_posts' => 'read_private_galleries',
        'delete_post' => 'delete_gallery'
    )
);

register_post_type( 'gallery', $args );
}

我还用一种全新的自定义帖子类型测试了这一点，无论功能类型如何，我都会遇到相同的问题，例如即使删除它并添加我的自定义帖子也是如此：

'capability_type' => array('movie','movies');

与Magicroundabout快速聊天后，后者指出了贾斯汀· 塔德洛克（Justin Tadlock）的有用资源，结果表明，除非您对角色使用add_cap（例如，以下自定义帖子类型），否则自定义帖子类型的功能实际上并不存在。

add_action( 'init', 'register_cpt_gallery' );

function register_cpt_gallery() {
$labels = array( 
    'name' => _x( 'Galleries', 'gallery' ),
    'singular_name' => _x( 'Gallery', 'gallery' ),
    'add_new' => _x( 'Add New', 'gallery' ),
    'add_new_item' => _x( 'Add New Gallery', 'gallery' ),
    'edit_item' => _x( 'Edit Gallery', 'gallery' ),
    'new_item' => _x( 'New Gallery', 'gallery' ),
    'view_item' => _x( 'View Gallery', 'gallery' ),
    'search_items' => _x( 'Search Galleries', 'gallery' ),
    'not_found' => _x( 'No galleries found', 'gallery' ),
    'not_found_in_trash' => _x( 'No galleries found in Trash', 'gallery' ),
    'parent_item_colon' => _x( 'Parent Gallery:', 'gallery' ),
    'menu_name' => _x( 'Galleries', 'gallery' ),
);

$args = array( 
    'labels' => $labels,
    'hierarchical' => true,
    'description' => 'Image galleries for teachers classes',
    'supports' => array( 'title', 'editor', 'author'),
    'public' => true,
    'show_ui' => true,
    'show_in_menu' => true,
    'menu_icon' => get_bloginfo('template_url') . '/images/imagegallery.png',
    'show_in_nav_menus' => true,
    'publicly_queryable' => true,
    'exclude_from_search' => false,
    'has_archive' => true,
    'query_var' => true,
    'can_export' => true,
    'rewrite' => true,
    'capabilities' => array(
        'edit_post' => 'edit_gallery',
        'edit_posts' => 'edit_galleries',
        'edit_others_posts' => 'edit_other_galleries',
        'publish_posts' => 'publish_galleries',
        'read_post' => 'read_gallery',
        'read_private_posts' => 'read_private_galleries',
        'delete_post' => 'delete_gallery'
    ),
    // as pointed out by iEmanuele, adding map_meta_cap will map the meta correctly 
    'map_meta_cap' => true
);

register_post_type( 'gallery', $args );
}

应该在角色中添加其他功能，以使权限在后端中实际起作用，包括“管理员”，例如：

function add_theme_caps() {
    // gets the administrator role
    $admins = get_role( 'administrator' );

    $admins->add_cap( 'edit_gallery' ); 
    $admins->add_cap( 'edit_galleries' ); 
    $admins->add_cap( 'edit_other_galleries' ); 
    $admins->add_cap( 'publish_galleries' ); 
    $admins->add_cap( 'read_gallery' ); 
    $admins->add_cap( 'read_private_galleries' ); 
    $admins->add_cap( 'delete_gallery' ); 
}
add_action( 'admin_init', 'add_theme_caps');

我希望这对其他人有用。

加：

map_meta_cap => true

到您的$ args数组。你看这里，为多。希望能帮助到你！

恕我直言，您永远不会映射自己的能力。确保使用地图meta cap插件来这样做。 http://codex.wordpress.org/Function_Reference/map_meta_cap

我花了几天的时间尝试使用代码手动映射自定义上限。只需安装该插件，绘制您的帽子，然后在工作后停用即可。如果创建自定义角色，则需要成员插件。

我测试以确保我的角色具有这些能力的方式（有时您发誓但实际上没有）使调试页面如下：

    if( !function_exists( 'current_user_has_role' ) ){
        function current_user_has_role( $role ){
            $current_user = new WP_User( wp_get_current_user()->ID );
            $user_roles = $current_user->roles;
            $is_or_not = in_array( $role, $user_roles );
            return $is_or_not;
        }
    }

这将向您显示实际上具有的功能。

对于自定义帖子类型，我不建议使用钩子：

add_action( 'registered_post_type', 'your_func', 10, 2 );

相反，我建议使用：

add_filter( 'register_post_type_args', 'your_func', 10, 2 );
function your_func( $args, $name ) 
{
   if ( $name == "your_custom_post_name" ) 
   ...
}
