Or:

<form action="<?php echo $PHP_SELF?>" method="post">

[jamesa]

Or:

<form action="<?=$PHP_SELF?>" method="post">

I have to recommend against the last two versions. Unless you have an old or a non-default setup of PHP, this will not work and will throw a notice (requires register_globals on I believe).

Stick to $_SERVER['PHP_SELF'] and be safe!

the short tags version of coopster's is

<form action="<?= $_SERVER['PHP_SELF']?>" method="post">

and ergophobe and coopster are right, use the $_SERVER version

register_globals is always off by default now and shouldn't be turned on anyway.

Not complaining...just commenting... :)

1) We're running PHP v.4.3.3 and having no problem with $PHP_SELF. We do have register_globals=on...see (2)...

2) We were having trouble keeping sessions active without register_globals=on. Why shouldn't we?

Thanks!

Actually...to give you the exact syntax we use:

<form action="<?echo $PHP_SELF?>" method=post>

Of course...it works fine with our configuration.
