Problem with variables: PHP_SELF

frech

Hello to everybody!

I have a problem with a script, an internal search engine for some products. It consists in a form and the code checking, all in the same page (i.e. if(isset($_POST['submit'] ... else ...).

I tried to use the line
$db = mysql_connect("localhost", "user", "pwd");
and also
$db = mysql_connect("IP address of MySQL server", "user", "pwd");
but I obtain the same result.

It works perfectly in a locale environment, but when I put it on the web-site, it just "refreshes" itself, without any error message or useful results.

I suppose the problem is in the line
<form class="content" action="<?php echo("$_SERVER[PHP_SELF]"); ?>" method="POST">

Am I right? Any ideas?

Register_globals: Off

Thanks to anyone could help me.

Please post more code ...

Change the form tag to:

<form class="content" action="<?PHP echo $_SERVER['PHP_SELF']; ?>" method="POST">

but I don't think that this is a problem.

and to test add a die to the mysql_connect:

$db = mysql_connect("IP address of MySQL server", "user", "pwd") or die ("Connection error: ".mysql_error());

Additionally, add
ini_set("error_reporting",E_ALL);
on top of the script.

I tried, also the tip about error_reporting, and the server response is almost shocking: it can't find the url!!
So the problem is that the script isn't able to find itself...
Here is the address line that compares in IE:

[url]http://[/url]web site url/<br><b>Warning</b>:%20%20Undefined%20variable:%20%20_SERVER%20in%20<b>/home/.sites/40/site68/web/prova/occhiali/cerca.php</b>%20on%20line%20<b>205</b><br>

Any suggestions? How can it be possible that PHP_SELF is not recognized?

You may find something in the manual regarding predefined variables. Specifically, in the section where it discusses the $_SERVER superglobal.
