2011年1月的WordPress管理菜单大挑战(又名如何解决修改WordPress管理菜单系统时的一些挑战？)

时间：2011-01-15 作者：MikeSchinkel

这个问题有点独特

在a部分；挑战“or anyone else)与trac票据相关：#16048, #16050 和#16204.

目标是在试图修改WordPress管理菜单部分时，绕过以下屏幕截图所示的三（3）个问题：

获取；“微型站点”编辑律师时要突出显示的子菜单页（为此，我们需要能够将“当前”应用于子菜单项，并且some hooks in the _wp_menu_output() function 将提供此处所需的内容），

获取要链接到的律师菜单页链接/wp-admin/edit.php?post_type=attorney 编辑律师时same needed hooks in the _wp_menu_output() function 可以处理此问题）以及

获取；“微型站点”链接不触发；您没有足够的权限访问此页面错误*（这是要解决的最糟糕的问题，并且hook on the return value of user_can_access_admin_page() 可以很好地处理此问题。）

这三（3）个问题不仅仅是我的用例，它们是WordPress中配置管理菜单相关问题的象征。

WordPress团队中的一些人说这很简单，因此暗示我遗漏了一些东西（这可能是对的），但我已经研究这个问题好几个星期了，还没有找到解决方法，所以我创建了你在下面看到的插件(also downloadable from Gist) 作为问题的最简单用例示例。中的代码admin_menu2() 这是一个相当粗糙的方法，但这正是在WordPress中修改管理菜单所需要的。

请注意，我没有尝试使用新的remove_menu_page() 也不是新的remove_submenu_page() 3.1中的函数，因为创建插件需要更长的时间——我已经在admin_menu2() 我不相信他们会解决这个问题。

我需要什么

我需要两（2）件事中的一件：

我用这个插件暴露的问题的解决方案，并在这个问题和屏幕截图中解释（顺便说一句，I\'ll disqualify your solution 如果您使用PHP Output Buffering 要解决此问题的任何部分），或

让WordPress团队认识到确实需要这些挂钩，并让他们重新考虑自己在门票上的立场。

你是如何迎接挑战的pristine new copy of WordPress 3.1 （任何修订都可以），

下载、安装并激活；2011年1月WordPress管理菜单大挑战”插件（或download the plugin from Gist)，然后

遵循该插件的插件页面上的说明（参见以下屏幕截图），但基本上加载上面看到的屏幕截图，然后尝试找出所述的三（3）个问题：

幸运的是，有一线希望Andrew Nacin of the WordPress team offered to look at this 一旦我把它编码好了，我就把它张贴在这里，主要是让他评论和评论，也让其他人评论。我知道他很忙，但我真的希望他(or even you) 在v3的原始安装上安装此插件可能需要一些时间。看看他是否能解决这个问题。

如果你同意挑战是不可能的

如果在尝试了这个挑战后，你得出了与我相同的结论，并且如果你想看到WordPress管理菜单更具可配置性，请对这些trac票证发表评论(#16048 - #16050 - #16204) 投票支持这个问题。

我很乐意承认我错过了什么，如果我真的错过了，当然我可能会在这件事上完全脑死亡，有人会准确地指出怎么做。事实上，我真的希望最终会是这样；我宁愿错了，也不愿让它起作用，反之亦然。

这是插件，您还可以downloadable if from Gist:

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="/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.

Mike，我已经查看了代码和您理想的最终用例。。。坦率地说，其中一些在当前的系统中是不可能实现的。同样，您的要求：

获取；“微型站点”；编辑律师时要突出显示的子菜单页获取要链接到的律师菜单页链接/wp-admin/edit.php?post_type=attorney 编辑律师时，请获取；“微型站点”；链接不触发；您没有足够的权限访问此页面；错误，这里的关键问题是#2。

我尝试的是为律师添加一个自定义的帖子类型，并立即被提醒/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。实际编辑发生在/wp-admin/post.php?post=10&action=edit. 所以如果你真的与#2联系在一起。。。其他两个标准不起作用。

这就是#3未能实现的原因。。。我甚至无法尝试#1，因为我走不了那么远。

SO网友:wyrfel

嘿，Mike，您的问题#3是由于您指定($microsite, \'the_microsite_editor\'), 应该在哪里(__CLASS__, \'the_microsite_editor\').

Update: 在花了太多时间试图为我自己的插件解决一些类似的问题之后，我发现了一些可能有助于解决您的挑战的东西（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\'));
}
然后你只要打电话add_posttype_submenu_page() 具有相应的参数。这应该正确地将子菜单项添加到在register_post_type() 呼叫

结束
