我遇到了将自定义帖子类型的自定义功能分配给自定义角色的问题。
问题是我要删除自定义帖子类型的添加新（不使用CSS hack或取消设置菜单项）选项。我已经遇到过提出许多解决方案的答案，但没有一个完美无缺。
最接近我想要的是：
register_post_type( 'custom_post_type_name', array(
'capability_type' => 'post',
'capabilities' => array(
'create_posts' => 'do_not_allow', // false < WP 4.5, credit @Ewout
),
'map_meta_cap' => true, // Set to `false`, if users are not allowed to edit/delete existing posts
));
此代码删除了“添加新链接”，但它为功能分配了默认的帖子 slug。注意上述代码的第2行。如果我将其更改为我的自定义帖子类型slug，它将停止工作，我甚至无法进入帖子页面。
要记住的一件事是我正在使用自定义角色，默认情况下只有读取功能。
如果我还分配了 edit_posts 功能，那么我的目标就实现了，但用户也可以访问我不想要的帖子和评论。
Woocommerce正在这样做。我会深入研究woocommerce代码，并在注册产品和订单的地方添加此行。
'capabilities' => array( 'create_posts' => 'do_not_allow' ),
一切都按照我的意愿行事。我整天都在探索woocommerce代码，但无法找到它是如何做到这一点的。有人可以用另一双眼睛帮我解决这个问题吗？ ：）
非常感谢。感谢..

我已经向你提过，给我们提供一些关于你想要做的计划的更多细节？
以下是我认为对您有帮助的解决方案。
如果您想使用map_meta_cap => true，那么您需要更改capability_type以及您自己的类型，请参阅更多https://codex.wordpress.org/Function_Reference/register_post_type#capability_type
但是，如果您设置了自己的capability_type值，那么您需要为要添加的用户角色添加功能。
这是一个完整的例子。
if ( !class_exists( 'WPSE64458_CPT_Register' ) ) {
class WPSE64458_CPT_Register {
function __construct() {
add_action( 'init', array( $this, 'wpse64458_register_post_types' ), 5 );
add_action( 'admin_init', array( $this, 'wpse64458_add_caps' ), 5 );
add_filter( 'register_post_type_args', array( $this, 'wpse64458_modify_cpt_registry' ) , 10, 2 );
}
/**
* Register core post types.
*/
public function wpse64458_register_post_types() {
if ( ! is_blog_installed() || post_type_exists( 'member' ) ) {
return;
}
register_post_type( 'member',
apply_filters( 'wpse64458_callb_post_type_member',
array(
'labels' => array(
'name' => __( 'Members', 'domaintext' ),
'singular_name' => __( 'Member', 'domaintext' ),
'all_items' => __( 'All Members', 'domaintext' ),
'menu_name' => _x( 'Members', 'Admin menu name', 'domaintext' ),
'add_new' => __( 'Add New', 'domaintext' ),
'add_new_item' => __( 'Add new member', 'domaintext' ),
'edit' => __( 'Edit', 'domaintext' ),
'edit_item' => __( 'Edit member', 'domaintext' ),
'new_item' => __( 'New member', 'domaintext' ),
'view' => __( 'View member', 'domaintext' ),
'view_item' => __( 'View member', 'domaintext' ),
'search_items' => __( 'Search members', 'domaintext' ),
'not_found' => __( 'No members found', 'domaintext' ),
'not_found_in_trash' => __( 'No members found in trash', 'domaintext' ),
'parent' => __( 'Parent member', 'domaintext' ),
'featured_image' => __( 'Member image', 'domaintext' ),
'set_featured_image' => __( 'Set member image', 'domaintext' ),
'remove_featured_image' => __( 'Remove member image', 'domaintext' ),
'use_featured_image' => __( 'Use as member image', 'domaintext' ),
'insert_into_item' => __( 'Insert into member', 'domaintext' ),
'uploaded_to_this_item' => __( 'Uploaded to this member', 'domaintext' ),
'filter_items_list' => __( 'Filter members', 'domaintext' ),
'items_list_navigation' => __( 'Members navigation', 'domaintext' ),
'items_list' => __( 'Members list', 'domaintext' ),
),
'public' => true,
'show_ui' => true,
'capability_type' => 'member',
'map_meta_cap' => true,
'menu_icon' => 'dashicons-groups',
'publicly_queryable' => true,
'exclude_from_search' => false,
'hierarchical' => false, // Hierarchical causes memory issues - WP loads all records!
'rewrite' => array( 'slug' => 'member' ),
'query_var' => true,
'supports' => array( 'title', 'editor', 'thumbnail', 'excerpt' ),
'has_archive' => 'members',
'show_in_nav_menus' => true,
'show_in_rest' => true,
)
)
);
} // end of wpse64458_register_post_types
/**
* Get capabilities.
*
* @return array
*/
private function wpse64458_set_caps() {
$capabilities = array();
$capability_types = array( 'member' );
foreach ( $capability_types as $capability_type ) {
$capabilities[ $capability_type ] = array(
// Post type
"edit_{$capability_type}",
"read_{$capability_type}",
"delete_{$capability_type}",
"edit_{$capability_type}s",
"edit_others_{$capability_type}s",
"publish_{$capability_type}s",
"read_private_{$capability_type}s",
"delete_{$capability_type}s",
"delete_private_{$capability_type}s",
"delete_published_{$capability_type}s",
"delete_others_{$capability_type}s",
"edit_private_{$capability_type}s",
"edit_published_{$capability_type}s",
// Terms
// "manage_{$capability_type}_terms",
// "edit_{$capability_type}_terms",
// "delete_{$capability_type}_terms",
// "assign_{$capability_type}_terms",
);
}
return $capabilities;
}
/*
Add Capability
*/
public function wpse64458_add_caps(){
global $wp_roles;
if ( ! class_exists( 'WP_Roles' ) ) {
return;
}
if ( ! isset( $wp_roles ) ) {
$wp_roles = new WP_Roles();
}
$capabilities = $this->wpse64458_set_caps();
foreach ( $capabilities as $cap_group ) {
foreach ( $cap_group as $cap ) {
$wp_roles->add_cap( 'editor', $cap );
$wp_roles->add_cap( 'administrator', $cap );
}
}
}
public function wpse64458_modify_cpt_registry( $args, $post_type ){
// Do not filter any other post type
if ( 'member' !== $post_type ) {
// Give other post_types their original arguments
return $args;
}
if( current_user_can('editor') ) {
$args['capabilities']['create_posts'] = false;
}
// Give the custom-css-js post type it's arguments
return $args;
}
}
}
然后使用class
new WPSE64458_CPT_Register();
通过此示例，我禁用编辑器角色以添加新的成员发布功能。修改你喜欢的任何东西，或者你也可以做其他人。但你之前提到你已经尝试过跟随WooCommerce，实际上他们也是这样做的，
希望你有意义。
HappyCodding！

您可以通过以下脚本将特定用户角色限制为自定义帖子：
添加自定义角色
add_action('init','add_my_custom_role');
function add_my_custom_role() {
add_role('my_custom_role',
'Custom Role',
array(
'read' => true,
'edit_posts' => false,
'delete_posts' => false,
'publish_posts' => false,
'upload_files' => false,
'publish_posts' => false,
'create_posts' => false,
)
);
}
注册自定义帖子
add_action( 'init', 'my_custom_post_type');
function my_custom_post_type() {
$args = array(
'label' => __( 'Custom post', 'custom-text-domain' ),
'description' => __( 'Custom post', 'custom-text-domain' ),
'labels' => $labels,
'supports' => array( 'title', 'comments', 'revisions', ),
'hierarchical' => false,
'public' => true,
'show_ui' => true,
'rewrite' => $rewrite,
'capability_type' => array('custom_post','custom_post'),
'map_meta_cap' => true, // Set to `false`, if users are not allowed to edit/delete existing posts
);
register_post_type( 'custom_post', $args );
}
允许用户根据角色发布帖子
add_action('admin_init','custom_post_add_role_caps',999);
function custom_post_add_role_caps() {
// Add the roles you'd like to administer the custom post types
$roles = array('my_custom_role','editor');
// Loop through each role and assign capabilities
foreach($roles as $the_role) {
$role = get_role($the_role);
$role->add_cap( 'read' );
$role->add_cap( 'read_custom_post');
$role->add_cap( 'read_private_custom_post' );
$role->add_cap( 'edit_custom_post' );
$role->add_cap( 'edit_custom_post' );
$role->add_cap( 'edit_others_custom_post' );
$role->add_cap( 'edit_published_custom_post' );
$role->add_cap( 'publish_custom_post' );
$role->add_cap( 'delete_others_custom_post' );
$role->add_cap( 'delete_private_custom_post' );
$role->add_cap( 'delete_published_custom_post' );
}
}
