我正在寻找一种从默认的Worpdress Metaboxes中删除所有不超级文本的方法。

最好确保内容不仅通过CSS隐藏,而且实际上是从HTML中删除的,因此甚至不会出现在源中。

我对删除感兴趣的领域包括:

  1. 单击右上角的帮助按钮,并关联Div/html/html/文本
  2. 在右现在的仪表板上,我想删除与使用哪个主题以及WordPress版本以及更改主题按钮相关的文本。
  3. 在底部的“页面属性” Metabox上,它具有文本“需要帮助?使用屏幕右上角的“帮助”选项卡。我希望将此文本删除
  4. 在“摘录Metabox”下,有我想删除的文本
  5. 您可能还知道如何删除清理WordPress的任何其他文本。
有帮助吗?

解决方案

这是问题1的答案。现在没有足够的时间来完成其余的时间。

1.)删除管理员帮助链接按钮

不幸的是,wordpress不能提供钩子来影响管理员右上方的帮助按钮,但是您可以使用一个 有点肮脏的黑客 实现您要完成的目标。

现在您看到了:

Help Link Button in WordPress Admin
(资源: mikeschinkel.com)

现在您没有:

Help Link Button Removed in WordPress Admin
(资源: mikeschinkel.com)

通过打电话 contextual_helpadmin_notices 挂钩,当帮助链接按钮分别输出之前和之后立即调用的挂钩,您可以捕获输出缓冲区并使用违规的HTML删除 preg_replace(). 。这 ob_start()/ob_get_clean() PHP中的一对功能是您需要缓冲输出,然后捕获缓冲输出的Viola:

class RemoveAdminHelpLinkButton {
  static function on_load() {
    add_filter('contextual_help',array(__CLASS__,'contextual_help'));
    add_action('admin_notices',array(__CLASS__,'admin_notices'));
  }
  static function contextual_help($contextual_help) {
    ob_start();
    return $contextual_help;
  }
  static function admin_notices() {
    echo preg_replace('#<div id="contextual-help-link-wrap".*>.*</div>#Us','',ob_get_clean());
  }
}
RemoveAdminHelpLinkButton::on_load();

通常,您可以使用此技术来修改或删除WordPress生成的几乎所有HTML输出,通过找到挂钩后和之后,但请注意,这是一种非常脆弱的技术;如果另一个插件从您期望的内容中修改了HTML输出 preg_replace() 可能无法匹配。反正...

3.)从页面属性删除帮助文本metabox

要删除页面的帮助文本属性metabox不需要正则表达式,一个简单的 str_replace() 会做。 (注意找到合适的钩子要使用的时间最多。):

class RemovePageAttributesHelpText {
  static function on_load() {
    add_action('admin_notices',array(__CLASS__,'admin_notices'));
    add_action('dbx_post_sidebar',array(__CLASS__,'dbx_post_sidebar'));
  }
  static function admin_notices() {
    ob_start();
  }
  static function dbx_post_sidebar() {
    $match_text = '<p>Need help? Use the Help tab in the upper right of your screen.</p>';
    echo str_replace($match_text,'',ob_get_clean());
  }
}
RemovePageAttributesHelpText::on_load();

当您想完成所有操作时,您还可以使用另一种方法 'gettext' 钩。以下代码从页面属性Metabox中删除了帮助文本:

class RemovePageAttributesHelpText {
  static function on_load() {
    add_filter('gettext',array(__CLASS__,'gettext'),10,4);
  }
  function gettext($translation, $text, $domain) {
    if ($text=='Need help? Use the Help tab in the upper right of your screen.') {
      $translation = '';
    }
    return $translation;
  }
}
RemovePageAttributesHelpText::on_load();

请注意,我谨慎使用此钩子,因为它被称为每页负载数百次。 577次仅是为了加载管理仪表板,例如我刚刚测试。因此,如果您使用它,请确保不做任何计算上的事情 “昂贵的” 例如运行RAW SQL查询或类似查询。

4.)从 “摘录Metabox”

我们将使用Technique#3的选项#2从摘录Metabox中剥离帮助文本 (我包括技术#3中的代码,因此该代码替换了#3中的代码):

class RemoveUnwantedPageEditingText {
  static function on_load() {
    add_action('admin_notices',array(__CLASS__,'admin_notices'));
    add_action('dbx_post_sidebar',array(__CLASS__,'dbx_post_sidebar'));
  }
  static function admin_notices() {
    ob_start();
  }
  static function dbx_post_sidebar() {
    $html = str_replace('<p>Need help? Use the Help tab in the upper right of your screen.</p>','',ob_get_clean());
    echo str_replace('Excerpts are optional hand-crafted summaries of your content that can be used in your theme.' .
     ' <a href="http://codex.wordpress.org/Excerpt" target="_blank">Learn more about manual excerpts.</a>','',$html);
  }
}
RemoveUnwantedPageEditingText::on_load();

其他提示

杰克·戈德曼(Jake Goldman)在WordCamp Mid-Atlantic的出色演讲提供了一个绝佳的指南: http://www.cmurrayconsulting.com/wordpress-tips/customizing-wordpress-admin/#more-939

下载幻灯片下方出现的良好的主题。 (他问,如果您使用他的代码,请在您的代码评论中将其归因于他。)

他提到您可以按以下方式获得所有窗口小部件ID:var_dump($ wp_meta_boxes ['dashboard']);

您可以:unset($ wp_meta_boxes ['dashboard'] ['normal'] ['core'] ['dashboard_right_now']);

然后使用wp_add_dashboard_widget()添加自己的小部件。

查看WP-ADMIN/INCLAY/DASHBOARD.PHP以获取函数,WP_DASHBOOD_RICHT_NOW()用于添加内容的模型(根据需要删除主题信息。)
