是否遇到过使用manage_options 页面的功能。。。真的不需要吗？嗯，我遇到过这样的情况。

这可能是一个更普遍的问题add_submenu_page, 所以不仅仅是针对我的用例。

我看着add_dashboard_page 它只是add_submenu_page:

function add_submenu_page( $parent_slug, $page_title, $menu_title, $capability, $menu_slug, $function = \'\' ) {
    global $submenu;
    global $menu;
    global $_wp_real_parent_file;
    global $_wp_submenu_nopriv;
    global $_registered_pages;
    global $_parent_pages;

    $menu_slug = plugin_basename( $menu_slug );
    $parent_slug = plugin_basename( $parent_slug);

    if ( isset( $_wp_real_parent_file[$parent_slug] ) )
        $parent_slug = $_wp_real_parent_file[$parent_slug];

    if ( !current_user_can( $capability ) ) {
        $_wp_submenu_nopriv[$parent_slug][$menu_slug] = true;
        return false;
    }

    // If the parent doesn\'t already have a submenu, add a link to the parent
    // as the first item in the submenu. If the submenu file is the same as the
    // parent file someone is trying to link back to the parent manually. In
    // this case, don\'t automatically add a link back to avoid duplication.
    if (!isset( $submenu[$parent_slug] ) && $menu_slug != $parent_slug ) {
        foreach ( (array)$menu as $parent_menu ) {
            if ( $parent_menu[2] == $parent_slug && current_user_can( $parent_menu[1] ) )
                $submenu[$parent_slug][] = $parent_menu;
        }
    }

    $submenu[$parent_slug][] = array ( $menu_title, $capability, $menu_slug, $page_title );

    $hookname = get_plugin_page_hookname( $menu_slug, $parent_slug);
    if (!empty ( $function ) && !empty ( $hookname ))
        add_action( $hookname, $function );

    $_registered_pages[$hookname] = true;
    // backwards-compatibility for plugins using add_management page. See wp-admin/admin.php for redirect from edit.php to tools.php
    if ( \'tools.php\' == $parent_slug )
        $_registered_pages[get_plugin_page_hookname( $menu_slug, \'edit.php\')] = true;

    // No parent as top level
    $_parent_pages[$menu_slug] = $parent_slug;

    return $hookname;
}

老实说，我似乎没有任何东西可以通过插入现有的仪表板页面来更改功能。所以我在试着决定使用remove_submenu_page 然后尝试重新声明相同的子菜单。我知道我需要注意一些事情（如果页面使用的显示功能有任何额外的功能检查或显示对站点至关重要的内容）。第二双眼睛盯着这些东西总是很有帮助的，这样我就不会把事情弄得太复杂了。谢谢大家！

多亏了@toscho和@userabuser，我得到了以下信息：

function wpse_71303_change_menu_cap()
{
    global $submenu;
    foreach ($submenu[\'index.php\'] as $dashboard => $key) {
        if ($key[0] == \'Analytics360°\') {
            $submenu[\'index.php\'][$dashboard][1] = \'analytics\';
        }
    }
}
add_action( \'admin_head\', \'wpse_71303_change_menu_cap\' );

如果我运行print_r($submenu) I do see the new capability - but I still can\'t access the menu item under the client role I created (with theanalytics\\u 360 `功能）（使用成员插件创建）。可能开火太晚了？肯定有点奇怪。一如既往地感谢！

The code from Update works for anyone that comes across this. It was an unneeded check around add_dashboard_page() giving me the issue.

add_action( \'admin_head\', \'wpse_71303_change_menu_cap\' );

/**
 * Change the capability to access an admin menu item.
 *
 * @wp-hook admin_head
 * @return void
 */
function wpse_71303_change_menu_cap()
{
    global $menu;

    foreach ( $menu as $key => $item )
    {
        // Find menu by name
        if ( \'Tools\' === $item[0] ) // default cap: \'edit_posts\'
        {
            $menu[ $key ][1] = \'new_capability\';
        }
    }
}

/////////////////////////////////////////////////
// ...this goes in my class `init()` function...
    add_action( \'admin_head\', array( $this, \'cv_adjust_submenu_permissions\') );

/////////////////////////////////////////////////

    function cv_adjust_submenu_permissions() {
        global $submenu;
        //error_log(print_r($submenu, true));
        foreach ( $submenu[\'CiviCRM\'] as $key => $item ) {
            // change CiviCRM... Settings submenu item capability
            if ( \'civi_options\' === $item[2] ) { // default capability: \'access_civicrm\'
                $item[1] = \'administer_civicrm\'; // new capability
                $submenu[\'CiviCRM\'][$key] = $item;
            }
        }
    }
