Error on page

[martman]

I am useing php for windows with apache for windows and when I open the admin page for the script I want to use. I get the following error message
<b>Notice</b>: Undefined variable: PHP_SELF in <b>d:\program files\apache group\apache\htdocs\advt\admin.php</b> on line <b>36</b><br />
<form method="post" action="?action=login"><input type="hidden" name="PHPSESSID" value="502cf8939a3388aa22e9c4cfa1d42ea1" />

This is the line from the code
echo " <form method=\"post\" action=\"$PHP_SELF?action=login\">\n";

is it the code or php not set up right ? Thanks in advance for any help

What version of PHP are you running? Are global variables on?

You might want to change $PHP_SELF to $_SERVER['PHP_SELF']

and for this line,
<form method="post" action="?action=login"><input type="hidden" name="PHPSESSID" value="502cf8939a3388aa22e9c4cfa1d42ea1" />

Change it to:

<form method="post" action="<?= _$SERVER['PHP_SELF'] ?>">
<input type="hidden" name="action" value="login">
<input type="hidden" name="PHPSESSID" value="502cf8939a3388aa22e9c4cfa1d42ea1" />

This is because Netscape doesn't accept actions with variables in them. =\

I am useing php 4.2.3 could not find anything about global variables. I changed the code with your suggestion and the page wouldn't even show changed code back. Thanks anyway try another script.
