Looking at the bottom of your wp-config.php file in the WordPress root directory will let you find something like this:
if ( !defined('ABSPATH') ) define('ABSPATH', dirname(__FILE__) . '/');For an example file have a look here:
http://core.trac.wordpress.org/browser/trunk/wp-config-sample.phpYou can make use of this constant called ABSPATH in other places of your WordPress scripts and in most cases it should point to your WordPress root directory.
Note: This answer is really old and things may have changed in WordPress land since.
I am guessing that you need to detect the WordPress root from your plugin or theme.
I use the following code in FireStats to detect the root WordPress directory where FireStats is installed a a WordPress plugin.function fs_get_wp_config_path() { $base = dirname(__FILE__); $path = false; if (@file_exists(dirname(dirname($base))."/wp-config.php")) { $path = dirname(dirname($base))."/wp-config.php"; } else if (@file_exists(dirname(dirname(dirname($base)))."/wp-config.php")) { $path = dirname(dirname(dirname($base)))."/wp-config.php"; } else $path = false; if ($path != false) { $path = str_replace("\\", "/", $path); } return $path; }This an old question, but I have a new answer. This single line will return the path inside a template: 🙂
$wp_root_path = str_replace('/wp-content/themes', '', get_theme_root());echo
ABSPATH;// This shows the absolute path of WordPressABSPATHis a constant defined in the wp-config.php file.You can use get_site_url() function to get the base url of the wordpress site.
For more information, please visit http://codex.wordpress.org/Function_Reference/get_site_url
There are 2 answers for this question Url & directory. Either way, the elegant way would be to define two constants for later use.
define (ROOT_URL, get_site_url() ); define (ROOT_DIR, get_theme_root() );I think this would do the trick:
function get_wp_installation() { $full_path = getcwd(); $ar = explode("wp-", $full_path); return $ar[0]; }Please try this for get the url of root file.First Way:
$path = get_home_path(); print "Path: ".$path; // Return "Path: /var/www/htdocs/" or // "Path: /var/www/htdocs/wordpress/" if it is subfolderSecond Way:
And you can also use "ABSPATH" this constant is define in wordpress config file.If you have WordPress bootstrap loaded you can use
get_home_path()function to get path to the WordPress root directory.For retrieving the path you can use a function
<?php $path = get_home_path(); ?>. I do not want to just repeat what had been already said here, but I want to add one more thing:If you are using windows server, which is rare case for WordPress installation, but still happens sometimes, you might face a problem with the path output. It might miss a “\” somewhere and you will get an error if you will be using such a path. So when outputting make sure to sanitize the path:
<?php $path = get_home_path(); $path = wp_normalize_path ($path); // now $path is ready to be used :) ?>theme root directory path code
<?php $root_path = get_home_path(); ?> print "Path: ".$root_path;Return “Path: /var/www/htdocs/” or “Path:
/var/www/htdocs/wordpress/” if it is subfolderTheme Root Path
$theme_root = get_theme_root(); echo $theme_rootResults:- /home/user/public_html/wp-content/themes
I like @Omry Yadan’s solution but I think it can be improved upon to use a loop in case you want to continue traversing up the directory tree until you find where
wp-config.phpactually lives. Of course, if you don’t find it and end up in the server’s root then all is lost and we return a sane value (false).function wp_get_web_root() { $base = dirname(__FILE__); $path = false; while(!$path && '/' != $base) { if(@file_exists(dirname($base)).'/wp-config.php') { $path = dirname($base); } else { $base = dirname($base); } } return $path; }I like the accepted answer and @cfx’s solution, but they can be consolidated a bit more:
function base_dir () { $path = dirname(__FILE__); while (true) { if (file_exists($path."/wp-config.php")) { return $path."/"; } $path = dirname($path); } }This allows for you to find the base directory in files that are not loaded by WordPress, such as dynamically-created javascript and css files.
