Dynamically show content based on url with PHP

[soulscriber]

Hi,

 

I'm relatively new to PHP.  I have a shopping cart template (leftcolumn template), that I want to show a different div depending on what the URL of the page is.

 

For example, if the category id in the url is 250, then I want a certain div to display, but if the category url is 248, then I want a different div to display.

 

Basically, how do I fetch the url info and then have that info change the content on the fly.  Remembering that this is a template file.

 

Any help would be greatly appreciated, thanks!

$id  =  $_POST["id"];
if ( $id == "1" ) {
echo '<div>DIV 1</div>';
}
elseif ( $id == "2" ) {
echo '<div>DIV 2</div>';
}
else ( $id == "3" ) {
echo '<div>DIV 3</div>';
}

say the URL is www.blah.com/index.php?id=243

 

<?php

$id =  $_GET['id'];

?>

 

$id will contain the value 243
