<? echo $nav; ?> ignored

[Anon]

Hi all,

Embarrassingly, I am new to PHP and stumped.

I have a live site I've recently started admining, and all works fine. The machines are Unix. At home, I'm trying to replicate the functionality, and all PHP works accept when I reference code at the top of an inc file.

The code at the top is -

if (strpos($SCRIPT_NAME, 'download')) {
$nav = "download";
$js_num = 3;
}

This should update an image based on a page -

<img src="/images/navigation/<? echo $nav; ?>all_off.gif" width="445" height="25" border="0" usemap="#<? echo $nav; ?>map"></a>

It fails. I have a similar situation with a sash that has page specific content and it works fine in the same page. My -

include("$DOCUMENT_ROOT/template/filename.inc");

works dandy also. Any ideas? Me thinks it has something to do with the line -

if (strpos($SCRIPT_NAME, 'download')) {

and the value of $SCRIPT_NAME, but I can't find it anywhere. Any idea where in apache/php4 for Win32 I would find where this value is set, or even on unix/apache/php? On the live servers which again are Unix/linux it knows when I visit /download/ to update inages/etc with the proper foldername value, but I can't for the life of me find it.

Any help you could throw my way would be a beautiful thing.

Happ new year.

$SCRIPT_NAME is an environmental variable inherited from Apache. If you're not running Apache, it may or may not exist.

Forgot to mention: see $PHP_SELF.

Great. Thanks much for the info Steve. I am on Apache in both cases. Unix at work, Win32 at home.

Any idea where $SCRIPT_NAME could be set? Is there a specific location?

Thanks again,

Eric

If you're running Apache, it should already be set to the value of the current script. Try echoing the value of $SCRIPT_NAME to check. All of the currently active environment, cookie, et cetera variables can be examined with the phpinfo() function, which prints out all sorts of interesting information.

Thanks again Steve. Your suggestion of using $PHP_SELF did the trick, but I'm really interested in getting it identical to my unix machines. I'll try what you suggested.

Thanks again. -E..

$PHP_SELF would be just as useful on your unix machines.
