Hi all,
I'm somewhat new to php, though I have played a bit with the language. I'm
currently learning the language, and I'm having a problem passing variables
through "URL query". Here is what I have:
A simple HTML file that contains:
<A HREF="test.php?var=test"> Hi, this is a test! </A>
and a php file that contains:
<?php
echo( "Welcome to our Web site, $var!" );
?>
However, when I click on the link on the HTML file, I dont get the value of
$var passed to the php script. I have also tried passing multiple variables
separated by &, and none of those gets passed to the php script.
The files are hosted on a local Debian etch server running apache 2.0.54 and
php 4.3.10.
Is there something I need to check/change in the config files of apache or
php?
Regards,
IraqiGeek

Try $_GET['var'].
echo( "Welcome to our Web site, {$_GET['var']}!" );
Two things you should note:
- using $var would be using register_globals which is depricated.
(http://us2.php.net/register_globals)
- echoing out get variables can lead to a XSS attack. (read
http://ha.ckers.org/xss.html)
As many like to point out, please read http://phpsec.org/ for some
security articles since most tutorials always strip any security
related code for simplicity.
