How to obtain wordpress root url (ABSPATH changes on each page)
提问by CodeVirtuoso
I have wordpress installed at:
我在以下位置安装了 wordpress：
When on homepage, the ABSPATH constant outputs exactly that, but when you navigate off to some other page, like:
在主页上时， ABSPATH 常量输出完全相同，但是当您导航到其他页面时，例如：
http://example.com/wordpress/contact
http://example.com/wordpress/contact
the ABSPATH also turns to:
ABSPATH 也变成：
http://example.com/wordpress/contact
http://example.com/wordpress/contact
The question is, how can I obtain the actual root (marked in bold) no matter on which page I am - without hard-coding it?
问题是，无论我在哪个页面上，我怎样才能获得实际的根（以粗体标记） - 无需对其进行硬编码？
I'm a bit confused with why ABSPATH changes value, aren't constants unchangeable once they are defined?
我对为什么 ABSPATH 更改值感到有些困惑，常量一旦定义就不是不可更改的吗？
Thanks!
谢谢！

I had the same issue on an admin page. Not only do you have to avoid the extra folder that gets inserted, WP may be installed in a folder itself.
我在管理页面上遇到了同样的问题。您不仅要避免插入额外的文件夹，而且 WP 可能会安装在文件夹本身中。
Here is a way, albeit somewhat convoluted and written for clarity, that makes the adjustments for these various items. It does avoid DIRECTORY_SEPARATORissues as well:
这里有一种方法，虽然有些复杂，并且为了清晰起见，可以对这些不同的项目进行调整。它也确实避免了DIRECTORY_SEPARATOR问题：
if (!defined(PLUGINUPDATEMGR_DOMAIN))
define("PLUGINUPDATEMGR_DOMAIN", strtolower( $_SERVER['HTTP_HOST'] ) );
$wprootbase = strtolower( site_url() );
$wprootstart = strpos( $wprootbase, PLUGINUPDATEMGR_DOMAIN ) +
strlen( PLUGINUPDATEMGR_DOMAIN ); // + 1 to strip the leading slash/backslash
$wprootend = strlen( $wprootbase );
$wproot = substr( $wprootbase, $wprootstart, $wprootend );
echo "Local WP path = '" . $wproot . '"';
Shaken, not stirred, output:
摇动，不搅拌，输出：
Local WP path = '/wp/wordpress-3.4.2"
Of course, YMMV =;?)
当然，YMMV =;？）

ABSPATH returns the absolute path to the php file in the server such as /var/www/wordpress/, do check your wordpress install.
ABSPATH 返回服务器中 php 文件的绝对路径，例如 /var/www/wordpress/，请检查您的 wordpress 安装。
