$PHP_SELF

[rfrenke]

I have a login page, and in the form tag I have the action set to:

action=&quot;<?php echo $PHP_SELF; ?>&quot;

Now I have tried both of these setups:

<form name=&quot;login&quot; method=&quot;post&quot; action=&quot;<?php echo $PHP_SELF; ?>&quot;>

<form name=&quot;login&quot; method=&quot;post&quot; action=&quot;<?php echo ($_SERVER[$PHP_SELF]); ?>&quot;>

And nothing happens. When I do a view source, this is what I see:

<form name=&quot;login&quot; method=&quot;post&quot; action=&quot;&quot;>

This page used to work until I upgraded to apache 1.3.26 & php 4.2.3 . Would the upgrade have anything to do with it?

Try:
<?php echo $_SERVER['PHP_SELF']; ?>

To elaborate on sleipnir's post:

$_SERVER[$PHP_SELF]);

The array key you refer to is a variable, namely $PHP_SELF, which is as you know from your testing is uninitialized, i.e. empty.

As sleipnir recommeds, use the $_SERVER[] array and enclose the literals that refer to the array elements in quotes.

$PHP_SELF is not available after ig register_globals is off (after 4.2.0 default).
