Wordpress root directory

Question

How can retrieve root directory in wordpress...Please help.......

Answer 1

Just echo this:

echo $_SERVER['DOCUMENT_ROOT'];

Answer 2

You can get blog url with get_bloginfo('url') However, dunno if you can get wp root. However, why do you need that?

Answer 3

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.php

You 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.

Answer 4

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;
}
