Retrieve WordPress root directory path?

Question

How can I retrieve the path to the root directory in WordPress CMS?

Answer 1

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 :)

?>

Answer 2

If you have WordPress bootstrap loaded you can use get_home_path() function to get path to the WordPress root directory.

Answer 3

   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 subfolder

Second Way:

And you can also use 

    "ABSPATH"

this constant is define in wordpress config file.

Answer 4

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.php actually 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;
}

Answer 5

I think this would do the trick:

function get_wp_installation()
{
    $full_path = getcwd();
    $ar = explode("wp-", $full_path);
    return $ar[0];
}

Answer 6

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 subfolder

Theme Root Path

 $theme_root = get_theme_root();
 echo $theme_root

Results:- /home/user/public_html/wp-content/themes
