WordPress - 自定义帖子类型,自定义角色,自定义功能

Question

我遇到了一个问题,即将自定义帖子类型的自定义功能分配给自定义角色.

问题是我想删除我的自定义帖子类型的添加新(不带CSS黑客或取消设置菜单项)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.

最接近我想要的是这个:

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post slug.注意上面代码的第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,默认情况下只具有读取功能.

如果我还分配了edit_posts功能,那么我的目标就实现了,但是用户也可以访问我不想要的帖子和评论.

Woocommerce正在这样做.我深入研究了woocommerce代码并在其注册产品和订单的地方添加了这一行.

'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？:)

非常感激.谢谢..

我已经向您提到过，请给我们提供有关您想做的计划的更多细节？

这是我认为对您有帮助的解决方案。

如果您想使用，map_meta_cap => true那么您还需要更改capability_type自己的类型，请参阅更多信息https://codex.wordpress.org/Function_Reference/register_post_type#capability_type

但是，如果您设置自己的capability_type值，那么您将需要向您想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' ),

              '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' ),

            ),
            'public'              => true,

            'hierarchical'        => false, // Hierarchical causes memory issues - WP loads all records!
            'rewrite'            => array( 'slug' => 'member' ),
            'query_var'           => 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",

        );
      }

      return $capabilities;
    }

    /*
      Add Capability
     */
    public function wpse64458_add_caps(){

      global $wp_roles;

      if ( ! class_exists( 'WP_Roles' ) ) {

      if ( ! isset( $wp_roles ) ) {

      $capabilities = $this->wpse64458_set_caps();

      // 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;

    }


  }
}

然后继承class与new WPSE64458_CPT_Register();

在这个示例中，我禁用编辑者角色来添加新的成员帖子功能。修改您喜欢的任何内容，或者您​​也可以执行其他操作。但你之前提到你已经尝试关注 WooCommerce，实际上他们也是这样做的，

希望它对你有意义。

快乐编码！
