register_globals = off

[DaRkZeAlOt]

Hi,
I changed my provider and it seems to be so that the new one uses "register_globals = off". Because of that i have to rewrite big parts of my site. Is there any other way (what can i do when i've a buch of variables that aren't defined sometimes before they getting used) ?

P.S.: I cant change the register_globals setting through the .htaccess file (like written on php.net) ...

extract ($POST); //for posted data
extract ($FILES); //for uploaded files
extract ($GET); //for querystring data
extract ($SESSION); //for session data
extract ($_COOKIE); //for cookie data

whatever... do this before you want to use the normal $variable way, instead of the $_POST['variable']

and don't use them all, only the ones you need

This solves my problem only partwise. I've code like :

if($mode == "")
  {
  ...
  }

if($mode == "anything")
  {
  ...
  }

if($mode == "something")
  {
  ...
  }

The first one is for using the page without any special target. The other ones are if the page is visited from a special link like "main.php?mode=anything". I'm using many variables in this way.

extract ($_GET);

will create $mode out of $_GET['mode']

and any other $_GET variables from the querystring

I think we nearly have it now 😉 . One problem left : if i've some variables that are in use (through $_GET) an some that are not i still get an error message. When i don't have any variables i can solve the problem with :

if(!extract($_GET))
  $mode = "NULL";
  $something = "NULL";

But in this case this isn't possible (besause i'm getting SOME, but not ALL, depanding on the link the user used), so i tried :

if($_GET["sTeil"])
  $sTeil = $_GET["sTeil"];
else
  $sTeil = "";

if($_GET["sTeilValueMitte"])
  $sTeilValueMitte = $_GET["sTeilValueMitte"];
else
  $sTeilValueMitte = "";

Which din't work ... 😕 .And the last thing : I'm getting errors like "Undefined index: sTeil", what's that meaning ?

[laserlight]

undefined index means the array element corresponding to the given index does not exist, i.e. it isnt submitted in the form etc.

You might want to use [man]empty/man or [man]isset/man to determine if those variables exist when the script is run.

Sometimes a look into the function reference could be very helpfull 😃 ...

thx !

I am getting an error message which I know I am supposed to be able to solve.. But I am not even sure what is causing the jproblem. I get this message when I click on my submit button: the method POST is not supported by the page I am posting to.
How do i solve this?
