undefined variable _post and _server

[sofaman]

I'm new to php, I'm learning from a book at the minute.

I'm running:
apache web server 2.0.59
PHP 5.0.2
Mysql 5.0.24 (as a module not cgi)

The same versions as what the book uses.

I've installed a forum - no problems
I've created a database useing the cmd line
I can view the database in IE
When I try to 'insert' into the database via IE I get the following

with code:
if ($_post) {
  // create empty error variable
  $msg = "";

I receive undefined variable _post

so I tried :
<?
$browser = $_server['php_shelf'];
echo "the sniffer says: $browser" ;
?>

I get undefined variable _server

I've search here and php.net, I've looked through php.ini but not found anything I think might work

Please help

cheers

you have to use upper case with those matey!!!

and PHP_SELF (not php_shelf) not seen shelf anywhere ;)
try this..

[code]
<?php
if ($_POST) {
  // create empty error variable
  $msg = "";

I receive undefined variable _post

so I tried :
<?
$browser = $_SERVER['PHP_SELF'];
echo "the sniffer says: $browser" ;
?>
[/code]

NOTE: try not use short tags '<?' use '<?php' instead - and turn off teh short tags in your php.ini file otherwise any xml files will reek havoc!

ALSO $_SERVER['PHP_SELF'] returns the name of name of the current script NOT the browser (or user agent) check the manula for the super globals info....

Thank you so much they work a treat :D
I've never programmed where I NEEDED to use uppercase. I must of missed the part in the book :(

I think I will do the tutorials from this site next.

Thanks again :D
