Issue
On localhost. I have the following directory structure:
/share/www/trunk/wp-content/plugins/otherfolders
/share/www/portfolio/wp-content/symlink
Where symlink
is a symbolic link to /trunk/.../plugins/
. Basically, this is because I need to test multiple WordPress installs and set them up, but I don't want to have to move plugins around and copy and paste them everywhere.
However, sometimes I need to crawl up the directory tree to include a config file:
$root = dirname(dirname(dirname(dirname(__FILE__))));
if (file_exists($root.'/wp-load.php')) {
// WP 2.6
require_once($root.'/wp-load.php');
}
The folder always resolves to:
/share/www/trunk
Even when the plugin is being executed and included in
/share/www/portfolio/
.
Is it possible in PHP to include files in the share/www/portfolio
directory from a script executing in a symlink to the /share/www/trunk/.../plugins
directory?
While this problem only happens on my test server, I'd like to have a safely distributable solution so crawling up an extra level is not an option.
Solution
The problem that I see with your code is that __FILE__
resolves symlinks automatically.
From the PHP Manual on Magic Constants
... Since PHP 4.0.2,
__FILE__
always contains an absolute path with symlinks resolved ...
You can try using $_SERVER["SCRIPT_FILENAME"]
instead.
$root = realpath(dirname(dirname(dirname(dirname($_SERVER["SCRIPT_FILENAME"])))));
if (file_exists($root.'/wp-load.php')) {
// WP 2.6
require_once($root.'/wp-load.php');
}
Note that I added the realpath()
function to the root directory. Depending on your setup, you may or may not need it.
EDIT: Use $_SERVER["SCRIPT_FILENAME"]
instead of $_SERVER["PHP_SELF"]
for the file system path.
