$DOCUMENT_ROOT vs. $_SERVER

Client Joined: Oct 07, 2003 Posts: 735 Location: Ohio

One returns a local path to the www root.

What if I have my Nuke install in a subdomain for testing my module?

ServerName subdomain.example.com

I have dropdown boxes in my modules that I read the contents of some images folders, and then set that record to whatever image I want.

This no longer works because I am using a subdomain for testing and am getting an incorrect local path.

Code:

$urlofimages="$DOCUMENT_ROOT/modules/MILPACS/images/ranks/small/";

How can I get this to work no matter where my module is installed?

register_globals are off in the php.ini file aren't they. Crying or Very sad

What can I do here?

This works. Nevermind.

$IMAGEPATH = $_SERVER['DOCUMENT_ROOT'];
$urlofimages="$IMAGEPATH/modules/MILPACS/images/ranks/small/";

As images that 'belong' to a module should always placed within the modules directory, the link should be relative i.e.

Code:

$urlofimages='images/ranks/small/';

Don't forget there are other nuke variables already defined that you can use but you would have to declare them in the php file.

Code:

$nuke_url - this should be whatever is set in your nuke references


$module_name - MILPACS

This does not work.

Code:

$urlofimages='images/ranks/small/';

But this does.

Code:

$urlofimages="$IMAGEPATH/modules/MILPACS/images/ranks/small/";

*shrugs*

Thats great.
You might want to change the $IMAGEPATH to something slightly more unique though just in case something else tries to use it.
Perhaps $MIL_IMAGEPATH ?

I always use "modules/$module_name/images/image.jpg". You could also use "./modules/$module_name/images/image.jpg".

This will work regardless of where your nuke is installed as "." is also where modules.php is, which is where everything is "relative" to.
