URL Links failing with register globals switched off

[Spudgun]

Hi all

I need some help with url links! I've switched register globals off in the ini file, but have now discovered that url links like:
http://www.myserver.com/index.php?idx=1&idx2=2
no longer work. The variables are not being passed.

Can someone please help me with this?

Thanks

you need to access those variables like this:

$_GET['variablepassed']

instead of just:

$variablepassed

with register_globals off,

if you are using post simple use:

$_POST['postedvariable']

voila

Thanks mate - but I'm now getting "undefined index" errors...

[stolzyboy]

maybe post some code so we can check it out closer and what version of php are you using

[Spudgun]

ok..
I've got an image of a radar - on the radar I'm pulling data from the database and plotting points that can be clicked on. This opens a new window displaying data on that particular point on the radar.

print"<area onClick=\"popupPage('http://www.myserver.com/radar_detail.php?idx=$row2[34]')\" shape=\"circle\" coords=\"$x_true_1,$y_true_1,6\">";

This opens a new window and I have the following code in there:

$query = " select * from database where idx = $_GET['idx'] ";

The error I'm now getting is "undefined index idx".

All help appreciated!
thanks

try putting

extract($_GET);

before any places where you need to access a $variable, and take out the $_GET['variable']

Thanks. I've tried some other stuff too and finally got it to work using $REQUEST.
I'm happy its working now - but am confused. Can anyone please explain why $GET didn't work, but $_REQUEST did?😕

[stolzyboy]

not too sure why it wouldn't work, but $REQUEST will get the variable whether it is a get, post, file, session or any other, however, if you are ensured that it was a get var you were trying to get, $GET should have worked, it could be a php version issue i suppose, you could also try $HTTP_GET_VARS i suppose, for testing purposes

Thanks stolzyboy!
