Help with links and URL arguments

Crimsondrac

Hi All,

I am new to the forums but have been dabbling in PHP for a while. I am trying to create a page that displays a list of links and when you click on the link, the page resets to show data on that link. I found a good tutorial over at webmonky.com with code that I feel could work for me once tweaked. However, I can not even get the default code to work. The code at webmonkey is: Webmonkey Tutorial. The links get created correctly, with the ?id=1, but the page never reconfigures to show the data for record number 1.

I have been trying to figure out why for days but can not see what I am doing wrong. Anyone know of a better tutorial for what I am trying to do?

I am running PHP5 with MySQL 4 on WindowsXP IIS

First think I'd say is do not use that tutorial. Within the first 5 (non-empty) lines of PHP code in the second script, I've found 5 obvious problems with the script.

The main problem is that they're assuming register_globals is turned On, which it should never be. When you pass something in the URL (ex. ?id=1), you would access it using the $GET superglobal array (ex. $GET['id'] would be 1). More information on this superglobal and the others can be found here: [man]variables.predefined[/man].

IIS?? What is this IIS you speak of?? LOL May I suggest you run apache as php was meant to do, Great install script for win32 called xampp. at http://apachefriends.org.

As for your bug, what he said .. You have to initialize your vars because if not, if your setup will accept uninitialized vars it is a security hole..

Thanks for the responses but like I said, I am pretty new. I read everywhere that you are not supposed to use register globals anymore, but I can not find any info on what to do instead of using register globals. I looked at that link you gave me, but the information does not seem to be very informative as to how to use those superglobals. Or if it is, then it is above my head because it does not make much sense to me. Plus, 99% of the existing tutorials seem to still want to use register globals. How is someone supposed to learn how not to use register globals when all the tutorials and information out there only shows you how to program using r/g.

I did finally figure out how to get it working, but only by turning on R/G.
