[Resolved] I cannot pull information from URL Querystrings

Guilo

Hello,

I just made a Gentoo box, with Apache2 and php4 so that I could learn php and a non-windows enviornment.

My problem is that I am unable to pull information from a querystring, which I thought (perhaps incorrectly 😕) was as simple as refrenceing the variable.

name.php:

querystring:
mydomain.com/name.php?Firstname=Guilo

output:

Can someone please tell me what I've done wrong?

(I installed Gentoo sync'd portage and emerged mod_php which put on php mysql and apache other than that I've not changed anything related to php)

Search for register_variables in the manual, these forums, and/or google.

Even if register_variables is on, it won't work because PHP variable names are case-sensitive.

...the PHP on that machine is with register_globals set to off and there fore you must do:

$FirstName = $GET['FirstName'];

And only then you'll be able to use $FirstName as a variable...

Also
$Firstname
$FirstName
is 2 different variables. PHP variables names are case sensitive.
(Sorry, I am repeating what was already said, I see now.)

Awesome register_globals was the problem (along with the case) Thanks for the help.

just to clarify, "register_globals" was not the problem.

You DON'T want register_globals to be on.

a request variable should always be accessed using $GET $POST $REQUEST or $COOKIES for security and portablilty.

you mean instesd of

$FirstName = $GET['FirstName'];

u want to put....

$FirstName = $_GET['FirstName'];

make sure $GET has an ''

in fact make sure all do like for sessions and cookies etc. $POST. $GET, $REQUEST, $SERVER, $SESSION, $COOKIE...

i belive thats all of em 😛

Ok, Cool

I turned register_globals back off and am using $_*[' '] to pull down that kind of data now.

That way makes more sense to me anyway as far a programming and security.

Cause how hard is it to guess that my query strings are $Query anyway right?

...from my part back there ($GET instead of $_GET)... 😃

And besides - you're right: the globals are dangerous if not prevented so whatever is the setting of the hosting server just develop your code with globals turned off and you'll be fine...

If the problem you had is solved mark this thread resolved with the link below...
