2011年1月的WordPress管理员菜单挑战赛（又名如何在修改WordPress管理员菜单系统时解决一些挑战？）

这个问题有点独特。

这部分是我向WordPress团队（或其他任何人）发出的与Trac票相关的“挑战”：＃16048，＃16050和＃16204。

目标

目标是在尝试修改WordPress管理员菜单部分时解决以下屏幕快照中说明的三（3）个问题：

1. 获取在编辑律师时突出显示的“微型站点”子菜单页面（为此，我们需要以某种方式将“当前”应用于子菜单项_，并且_wp_menu_output（）函数中的某些钩子将在此处提供所需的功能），

2. 获得“律师菜单页面”链接以链接到/wp-admin/edit.php?post_type=attorney编辑律师时的链接（并且_wp_menu_output（）函数中所需的相同钩子可以处理此问题），以及

3. 获得“微型站点”链接，以不触发“您没有足够的权限来访问此页面”错误*（这是要解决的最讨厌的问题，返回值的钩子user_can_access_admin_page()可以很好地解决此问题。）

不只是我的用例

这三（3）个问题是针对我的用例，但它们是与在WordPress中配置管理菜单有关的问题的象征。

WordPress团队中的一些人说这很容易，因此暗示我缺少一些东西（可能是正确的），但是我已经研究了这个问题了好几个星期，却没有弄清楚如何解决它，因此我创建了您在下面看到的插件（也来自Gist下载的），作为问题的最简单的使用情况的例子。中的代码admin_menu2()有点黑，但这几乎是修改WordPress中的“管理菜单”所需要的。

请注意，我并未尝试使用3.1中remove_menu_page()的新remove_submenu_page()功能或新功能，因为创建该插件将花费更长的时间-我已经admin_menu2()从现有项目中获得了代码-而且我认为它们不会解决该问题。反正问题。

我需要什么？

我需要两（2）件事之一：

1. 解决该插件问题的解决方案，并在此问题和屏幕截图中说明（顺便说一句，如果您使用PHP Output Buffering解决此问题的任何部分，我将取消您的解决方案的资格），或者

2. 要让WordPress团队认识到确实需要这些钩子，并让他们重新考虑它们在票证上的位置。

您如何应对挑战？

1. 下载并安装WordPress 3.1 的原始新副本（可能会进行任何修订），

2. 下载，安装并激活下面的“ 2011年1月的WordPress管理员菜单挑战大赛”插件（或从Gist下载该插件），然后

3. 按照此插件的插件页面上的说明进行操作（请参见下面的屏幕截图），但基本上要加载上面看到的屏幕截图，然后尝试找出所描述的三（3）个问题：

一线希望

幸运的是，WordPress团队的安德鲁·纳辛（Andrew Nacin）提出了对它进行编码的建议，因此我主要是在此处发布内容供他审核和评论，并请他人发表评论。我知道他很忙，但我希望他（甚至您）可以花时间在v3.1的原始安装上安装此插件，看看他是否可以解决问题。

如果你同意的挑战是不可能的？

如果尝试这个挑战后，你来了同样的结论作为我，如果你想看到WordPress管理菜单上这些TRAC票更多配置请评论（＃16048 - ＃16050 - ＃16204）和投票这个问题了表示支持。

我会很高兴地承认我错过了一些东西

当然，我可能对此完全不知所措，有人可能会指出确切的操作方法。实际上，我真的希望最终成为事实。我宁愿错了，而且要有效，而不是相反。

这是插件

Plugin Name: The Great WordPress Admin Menu Challenge of Jan 2011
Description: <em>"The Great WordPress Admin Menu Challenge of Jan 2011"</em> was inspired by the WordPress team's apparent lack of understanding of the problems addressed by trac tickets <a href="http://core.trac.wordpress.org/ticket/16048">#16048</a> and <a href="http://core.trac.wordpress.org/ticket/16050">#16050</a> <em>(See also: <a href="http://core.trac.wordpress.org/ticket/16204">#16204</a>)</em> and suggestion that the <a href="http://wordpress.org/extend/plugins/admin-menu-editor/>Admin Menu Editor</a> plugin handles the use-cases that the tickets address. Debate spilled over onto Twitter with participation from <a href="http://twitter.com/nacin">@nacin</a>, <a href="http://twitter.com/aaronjorbin">@aaronjorbin</a>, <a href="http://twitter.com/petemall">@petemall</a>, <a href="http://twitter.com/westi">@westi</a>, <a href="http://twitter.com/janeforshort">@janeforshort</a>, <a href="http://twitter.com/PatchesWelcome">@PatchesWelcome</a>; supportive comments from <a href="http://twitter.com/ramsey">@ramsey</a>, <a href="http://twitter.com/brianlayman">@brianlayman</a>, <a href="http://twitter.com/TheLeggett">@TheLeggett</a>, a retweeting of @nacin's simple yet <em>(AFAICT)</em> insufficient solution by <a href="http://twitter.com/vbakaitis">@vbakaitis</a>, <a href="http://twitter.com/Viper007Bond">@Viper007Bond</a>, <a href="http://twitter.com/nickopris">@nickopris</a>, <a href="http://twitter.com/Trademark">@Trademark</a>, <a href="http://twitter.com/favstar_pop">@favstar_pop</a>, <a href="http://twitter.com/designsimply">@designsimply</a>, <a href="http://twitter.com/darylkoop">@darylkoop</a>, <a href="http://twitter.com/iamjohnford">@iamjohnford</a>, <a href="http://twitter.com/markjaquith">@markjaquith</a>, <a href="http://twitter.com/JohnJamesJacoby">@JohnJamesJacoby</a> and <a href="http://twitter.com/dd32">@dd32</a>.

Get the "Microsite" submenu page to be highlighted when editing an Attorney, 2.) Get the Attorney Menu Page link to link <a href="/wordpress//wp-admin/edit.php?post_type=attorney">here</a>  when editing an Attorney, and 3.) Get the "Microsite" link not to trigger a "You do not have sufficient permissions to access this page" error.  Here is <a href="https://mikeschinkel.com/websnaps/skitched-20110114-235302.png" target="_blank"><strong>a screenshot</strong> that attempts to illustrate the callenge</a>. The code can be found on gist <a href="https://gist.github.com/780709"><strong>here</strong></a>.

对于所有阅读本文的人，我真的希望您能提供帮助。

提前致谢。

迈克，我看了一下代码和您理想的最终用例……坦率地说，其中一些是当前系统无法实现的。同样，您的要求：

1. 获取到编辑律师时突出了“微型”子菜单页
2. 获取“律师菜单页面”链接以链接到/wp-admin/edit.php?post_type=attorney编辑律师时的链接
3. 获取“微型网站”链接，以不触发“您没有足够的权限访问此页面”错误

这里的关键问题是＃2。

我尝试了什么

我尝试为“律师”添加自定义帖子类型，但立即被提醒，这/wp-admin/edit.php?post_type=attorney将为您提供律师列表，而不是实际的编辑屏幕。实际的编辑发生在/wp-admin/post.php?post=10&action=edit。因此，如果您确实与＃2相关联，则其他两个条件将不起作用。

这就是为什么＃3实施失败的原因...而我什至无法尝试＃1，因为我做不到。

嗨，迈克，您的问题3是由于您指定的($microsite, 'the_microsite_editor')位置(__CLASS__, 'the_microsite_editor')。

更新：花了太多时间尝试解决我自己的插件的类似问题后，发现有些东西可能对您的Challenge有所帮助（请注意，函数是类下面的方法）：

function add_posttype_submenu_page($mytype, $label, $cap, $slug) {  
    /* we add two submenu pages to work around the 
       edit.php?post_type=...&page=...problem and have 
       our page called as admin.php?page=... instead */
    //first create a 'blind' pseudo-entry to register our page callback
    add_submenu_page($mytype, $label, $label, $cap, $slug, 
                     array( &$this, 'admin_'.$mytype ));
    //then create a real entry that 'calls' our pseudo-entry
    add_submenu_page('edit.php?post_type='.$mytype, $label, 
                     $label, $cap, 'admin.php?page='.$slug);
    /* then lets fix/hack the highlighting */
    global $plugin_page;
    global $submenu_file;
    if ($plugin_page == $slug) {
        // this next line highlights the submenu entry
        $submenu_file = 'admin.php?page='.$slug; 
        add_filter('parent_file', 
                   array(&$this, 'evil_parent_file_hack'));
    }
} 

function evil_parent_file_hack() {
    //we do this to get the parent menu properly highlighted, too
    //it only gets called on the submenu menu page in question
    global $self;
    global $parent_file;
    $self = $parent_file;
    remove_filter('parent_file', array(&$this, 'evil_parent_file_hack'));
}

然后，您只需add_posttype_submenu_page()使用相应的参数进行调用。这应该将子菜单项正确地添加到在register_post_type()通话过程中自动创建的菜单中。
