I need some quick help with php navigation

[Rockboy]

Hey,
I'm creating a web design website, and I'm adding some special discount pages. Instead of linking to pages like 'discount1.php' and so on, I think it would be much more professional (and easy) to do this: 'discounts.php?id=123'. But how do I do that? If anyone knows of a tuturial on how to do that, please let me know. Thanks!

Basically, you do something like this in discount.php:

Code Select Expand

$discount = $_GET['id];
if ($discount == 1) {
  ...stuff...
}

Of course, you want to sanitize the variable and make sure you only get what you're looking for.  I don't know of any tutorials, but you can start here:

http://www.php.net/variables.predefined

If you take a look at SMF's code, you will see many, many examples of how to grab variables from the URL.
