管理员的自定义角色功能未生效(无插件)

我已经从插件创建了一个自定义帖子类型。我添加了一个功能类型teacher. 然后，我向administrator添加了自定义功能。但问题是，在完成这段代码后，它第一次将上述功能添加到角色中。但当我进一步修改它时，它不会生效。就像我现在删除函数一样roles_to_edit_teacher, 仍然管理员将具有这些功能。那么如何解决这个问题呢？

function plugin_main_functions(){
register_post_type(\'teachers\', array(
    \'labels\' => array(
        \'name\'=>__(\'Teachers List\', \'Teachers\'),
        \'add_new\' => __(\'add new teacher\', \'Teachers\'),
        \'add_new_item\' => __(\'Add new teacher\', \'Teachers\')
        ),
    \'public\' => true,
    \'supports\'=> array(\'title\', \'editor\', \'thumbnail\'),
    \'menu_icon\' => \'dashicons-groups\',
    \'capability_type\' => array(\'teacher\',\'teachers\'),
    \'map_meta_cap\' => true

    ));

}
add_action(\'init\',\'plugin_main_functions\');

function roles_to_edit_teacher(){

    $admin = get_role(\'administrator\');


    $admin->add_cap(\'edit_teacher\');
    $admin->add_cap(\'edit_teachers\');
    $admin->add_cap(\'read_teacher\');
    $admin->add_cap(\'delete_teacher\');
    $admin->add_cap(\'delete_teachers\');
    $admin->add_cap(\'publish_teacher\');
    $admin->add_cap(\'create_teachers\');
}
add_action(\'init\', \'roles_to_edit_teacher\');

add_action(\'init\',\'plugin_main_functions\'); function plugin_main_functions(){ register_post_type(\'teachers\', array( \'labels\' => array( \'name\'=>__(\'Teachers List\', \'Teachers\'), \'add_new\' => __(\'add new teacher\', \'Teachers\'), \'add_new_item\' => __(\'Add new teacher\', \'Teachers\') ), \'public\' => true, \'supports\'=> array(\'title\', \'editor\', \'thumbnail\'), \'menu_icon\' => \'dashicons-groups\', \'capability_type\' => array(\'teacher\',\'teachers\'), \'map_meta_cap\' => true )); } register_activation_hook( __FILE__, function () { // Call function plugin_main_functions(), // The function where the custom post type is registered plugin_main_functions(); $admin = get_role(\'administrator\'); $admin->add_cap(\'edit_teacher\'); $admin->add_cap(\'edit_teachers\'); $admin->add_cap(\'read_teacher\'); $admin->add_cap(\'delete_teacher\'); $admin->add_cap(\'delete_teachers\'); $admin->add_cap(\'publish_teacher\'); $admin->add_cap(\'create_teachers\'); flush_rewrite_rules(); } ); register_deactivation_hook( __FILE__, function () { // Call function plugin_main_functions(), // The function where the custom post type is registered plugin_main_functions(); $admin = get_role(\'administrator\'); $admin->remove_cap(\'edit_teacher\'); $admin->remove_cap(\'edit_teachers\'); $admin->remove_cap(\'read_teacher\'); $admin->remove_cap(\'delete_teacher\'); $admin->remove_cap(\'delete_teachers\'); $admin->remove_cap(\'publish_teacher\'); $admin->remove_cap(\'create_teachers\'); flush_rewrite_rules(); } );

add_action(\'init\',\'plugin_main_functions\'); function roles_to_edit_teacher(){ if( $i_neet_to_remove_cap === true ) { $admin = get_role(\'administrator\'); $admin->remove_cap(\'some_capability\'); } if( $i_neet_to_add_cap === true ) { $admin = get_role(\'administrator\'); $admin->add_cap(\'some_capability\'); } }

嘿，我在我的localhost设置中得到了这个错误消息，但只有在启用Genesis框架的情况下；WordPress二十一行。当我想创建一个新帖子时，就会发生这种情况。如果我刷新页面，错误会重复，但帖子本身会被创建，一切似乎都很好。有人知道这是什么原因吗？Notice: Undefined offset: 0 in /var/www/secret/htdocs/wp-includes/capabilities.php on line 1067 Notice: Undefined offset: 0
