管理菜单-在子菜单页面上突出显示顶级菜单（不显示子菜单）

这是当前情况:

我正在编写一个具有顶级菜单页面的插件

该插件还包含其他子菜单页面

未为子菜单页面分配父子弹(因此它们不会出现在管理菜单中)

我的要求是执行以下操作:

管理菜单中仅具有顶层菜单页面菜单项(不应出现子菜单页面菜单项)

在子菜单页面上突出显示顶级菜单页面菜单项

我尝试给子菜单页面添加父子弹.当然,这会使它按预期显示在顶级菜单项下.然后,我尝试使用remove_submenu_page删除子菜单项.但是,由于这会删除整个子菜单页面,因此无法解决问题.

我相信这样做是合乎逻辑的,因为顶层菜单项将需要知道所访问的页面位于该菜单项之下,这是给父级附加项的原因.然后,问题是没有显示子菜单页面的菜单项.我找不到直接处理菜单项的功能.

这是正确的方法还是有更好的选择? 我可以利用动作/过滤器/挂钩执行我需要做的事情吗?

编辑#1:
做过一些进一步的研究/测试.在add_submenu_page调用中将menu_title参数设置为null或"可使标题不显示.但是,＆lt; li＆gt;包含子菜单项的菜单仍然存在,并且可以与之交互.当有很多子菜单页面时(如我的情况),空白的＆lt; li＆gt;元素将加起来并在菜单上创建一个长长的空白区域.这远非理想,因此,我仍在寻找解决方案.

编辑#2: 在@s_ha_dum发表评论后,尝试操纵$ submenu全局变量.但是,任何与页面有关的菜单部分的删除也会导致类似于remove_submenu_page的页面删除,从而使该页面无法访问.
This is the current situation:

I am writing a plugin that has a top-level menu page

The plugin also contains other sub-menu pages

The sub-menu pages are not assigned a parent slug (thus they do not appear in the admin menu)

My requirement is to do the following:

Have only the top-level menu page menu item in the admin menu (no sub-menu page menu items should appear)

Highlight the top-level menu page menu item when on a sub-menu page

I've tried giving a parent slug to the sub-menu pages. This, of course, makes it appear as expected under the top-level menu item. I then tried to remove the sub-menu item, by using remove_submenu_page. However, since that removes the entire sub-menu page, it doesn't solve the problem.

I believe the logical thing to do, is to give a parent slug, since the top-level menu item will need to know that the page being accessed falls under it. The problem then, is not showing the sub-menu page's menu item. I am unable to find a function that deals directly with the menu items.

Is this the right approach or is there a better alternative? Is there a action/filter/hook I can utilise to carry out what I need to do?

Edit #1:
Did some further research/testing. Setting the menu_title parameter to null or '' in the add_submenu_page call makes the title not appear. However, the <li> that contains the sub-menu item still does exist and can be interacted with. When there are numerous sub-menu pages (as in my case), the empty <li> elements will add-up and create a long blank area on the menu. This is far from ideal and as such, I'm still searching for a solution.

Edit #2: Tried manipulating the $submenu global after the comment from @s_ha_dum. However, any removal of the menu section pertaining to a page also results in removing the page similar to remove_submenu_page and thus rendering that page inaccessible.

- 不幸的是,该方法似乎与[remove_submenu_page](http://codex.wordpress.org/remove_submenu_page)相似,并且使访问该页面时抛出"您没有足够权限来访问此页面".信息.不过,我会进一步检查.谢谢你的建议.
  
  Unfortunately, that method seems to work similar to [remove_submenu_page](http://codex.wordpress.org/remove_submenu_page) and makes accessing the page throw a "You do not have sufficient permissions to access this page." message. I'll check up further on it though. Thanks for the suggestion.

- 您主页上的选项卡式界面会达到相同的目标吗?http://getbutterfly.com/how-to-create-a-tabbed-interface-for-your-wordpress-plugin/
  
  Would a tabbed interface within your main page achieve the same goal? http://getbutterfly.com/how-to-create-a-tabbed-interface-for-your-wordpress-plugin/

- 这是一个有趣的方法.我不确定我是否要在选项卡中加载所有不同的页面(总共大约8个左右).我想我可以做一些AJAX加载,在需要的时候加载单个页面的内容.我仍然有兴趣为原始问题找到解决方案.但是,我认为如果不修改核心文件(我不希望这样做),当前的WP版本可能是不可能的.我将检查选项卡式方法.谢谢你的建议.
  
  That's an interesting approach. I'm not entirely sure I want to have all the different pages (there are about 8 or so in total) loading in tabs though. I suppose I could do some AJAX loading where the individual page content is loaded as and when it is needed. I'm still interested in finding a solution for the original problem. However, I think it may not be possible for the current WP version without modifying the core files (which I do not wish to do). I'll check out the tabbed approach. Thanks for the suggestion.

这是一个较晚的答案,我不知道@Jay是否曾经解决过这个问题,但是对于有相同问题的任何人,这就是我的解决方法.

菜单页面

 function my_admin_menu() {

    add_menu_page(
        'Page title',
        'Menu title',
        'manage_options',
        'my_page',
        null,
        null,
        99
    ); 

    add_submenu_page(
        'my_page',
        'Subpage 1 title',
        'Subpage 1 menu title',
        'manage_options',
        'my_subpage_1',
        null
    );

    add_submenu_page(
        'my_page',
        'Subpage 2 title',
        'Subpage 2 menu title',
        'manage_options',
        'my_subpage_2',
        null
    );
}
add_action( 'admin_menu', 'my_admin_menu' ) );

function my_admin_head() {

    remove_submenu_page( 'my_page', 'my_subpage_1' );
}
add_action( 'admin_head', 'my_admin_head' );

有关删除_submenu_page ,请参见法典.

That's a bit of a late answer and I don't know if @Jay ever sorted it out, but to anyone having the same issue, here's how I fixed it.

Menu Pages

function my_admin_menu() {

    add_menu_page(
        'Page title',
        'Menu title',
        'manage_options',
        'my_page',
        null,
        null,
        99
    ); 

    add_submenu_page(
        'my_page',
        'Subpage 1 title',
        'Subpage 1 menu title',
        'manage_options',
        'my_subpage_1',
        null
    );

    add_submenu_page(
        'my_page',
        'Subpage 2 title',
        'Subpage 2 menu title',
        'manage_options',
        'my_subpage_2',
        null
    );
}
add_action( 'admin_menu', 'my_admin_menu' ) );

function my_admin_head() {

    remove_submenu_page( 'my_page', 'my_subpage_1' );
}
add_action( 'admin_head', 'my_admin_head' );

See the Codex for remove_submenu_page.
