Php and url

[Pera]

I am trying to pass an id with?string=string within my url so I can query off that information. The problem is that it is working within my production machine which uses Unix, but not my test machine which uses Windows. Do I need to set or add something to the httpd.conf file? I'm using Apache 1.3.33, PHP 4.3.10, MySQL 4.19 and PhpMyAdmin 2.6.1. My test machine is setup as localhost. Help!

How are you reading the value? You should be using $_GET['string'] or $_REQUEST['string'] but not $string.

Hi Pera and welcome to WebmasterWorld!

Try not to use $_REQUEST at all, as it may be easily modified.
Also turn register globals [de3.php.net] off, as they pose a high security breach

So in this example use $_GET['string'] as mcavic suggested

I'm putting a value in my url line using the?string=string (http://localhost.test.php?articlenum=17), so I can query off of it. I use the isset() and!empty() in an IF statement before I run my query. For some reason it is not working on my test machine. How can I test to see if the value is there? It is my id for my article, so I can display it based on the user selection. Like I mentioned, it worked in production and not in my test environment which is weird. That is why I think I need to modify the config file for some reason.

isset($_GET['variable_name']) always works for me, but I use LAMP systems for all my Web work.

Add this to the beginning of your script to see what is being sent to the script:

print_r($_GET);
