我正在寻找一种方法来删除默认worpdress元数据库中所有不必要的文本。
最好我想确保内容不仅通过CSS隐藏，而且实际上从HTML中删除，这样它甚至不会显示在源代码中。
我想删除的领域包括：
单击右上角的“帮助”按钮并关联DIV/HTML/text时，我想删除与正在使用的主题和wordpress版本相关的文本以及“更改主题”按钮
在没有CSS的情况下从管理菜单中删除不必要的文本

以下是问题#1的答案。现在没有足够的时间做剩下的事。
1.）删除管理员帮助链接按钮不幸的是，WordPress没有提供一个钩子来影响管理员右上角的帮助按钮，但是你可以使用一个有点脏的黑客来实现你想要实现的目标。
现在您可以看到：
现在您不需要：
通过调用contextual_help 和admin_notices 钩子，即在输出帮助链接按钮之前和之后立即调用的钩子，您可以捕获输出缓冲区并使用preg_replace(). 这个ob_start()/ob_get_clean() PHP中的一对函数是缓冲输出然后捕获缓冲输出所需的函数，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();
preg_replace() 可能无法匹配。无论如何3.）从页面属性元框中删除帮助文本要删除页面属性元框的帮助文本，不需要正则表达式，一个简单的str_replace() 可以（注意，找到要使用的正确挂钩花费的时间最多。）：
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();
\'gettext\' 钩以下代码从页面属性元框中删除帮助文本：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();
4.）从中删除文本；摘录Metabox
我们将使用技巧3中的选项2从摘录的Metabox中删除帮助文本（这一个我包括技巧3中的代码，所以这一个替换了技巧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();

Jake Goldman在大西洋中部WordCamp的精彩演讲提供了一个很好的指南：http://www.cmurrayconsulting.com/wordpress-tips/customizing-wordpress-admin/#more-939
下载幻灯片下方评论良好的主题。（他问，如果您使用他的代码，请在代码注释中将其归属于他。）
他提到，您可以按如下方式获得所有小部件ID：var\\u dump（$wp\\u meta\\u box[\'dashboard]）；
您可以：取消设置（$wp\\u meta\\u box[\'dashboard\'][\'normal\'][\'core\'][\'dashboard\\u right\\u now\'）；
然后使用wp\\u add\\u dashboard\\u widget（）添加您自己的小部件。
查看wp admin/includes/dashboard。php函数，wp\\u dashboard\\u right\\u now（）模型，用于添加内容（根据需要删除主题信息）

Alternativ非常简单：使用插件Adminimize, 这个插件有很多选项，你可以添加自己的选项。这个插件是我自己的，我会用更好的代码编写一个更新的插件。也许这有助于csutom解决方案读取源代码。
