Hi,
I'm making a site with php and I'm not sure if what I'm trying to do is possible. What I have is a navigation menu with links to a php file that searches an sql table for matching parameters. Is there a way to attach the element to search for to the end of the url or another way to do that?

Not sure if I explained that correctly

do you mean passing parameters in an url? You can do this as url:

(Toggle Plain Text)

somepage.php?parameter1=value&parameter2=anothervalue&parameter3 =etc

and this is how to get the parameters in somepage.php:

(Toggle Plain Text)

<?php
$param1 = $_GET['parameter1'] // $param1 contains now value
$param2 = $_GET['parameter2'] // $param2 contains now anothervalue

// the same counts for parameter3
?>

Yeah, that's what I was looking for.
Thanks

If you have global variables turned on you can just call the parameter by its name.

eg somepage.php?parametername=1234

then php will automatically create a variable for the parameter

<?
echo $parametername; // this will display the value 1234 no need for $_GET
?>

Using register_globals can lead to serious security issues.

Even without, if you switch to a server without global vars it can be a pain (you an turn them back on with a .htaccess file, but still like you said security issues). It's also considered sloppy code when you write it like that.

BTW, good to see another wings fan.

don't forget to read about sql injection!

Yeah there are quite a few vunerabilities you will need to check for. Check out www.securityfocus.com it says all the vunerabilities to different software, and how to fix them/exploit them.
