I've read lots of the threads for passing variables...so feel like I've tried a lot of different methods. But. Basically, I'm trying to pass a variable to an iframe that loads single.php, for displaying individual posts.
In category-5.php I have:
<a href="?p=<?php the_ID(); ?>?wh=1">link to post</a>
In single.php I have:
$wh = $_GET['wh'];
echo "wh=" . $wh;Doesn't work though. What am I doing wrong here? Any help greatly appreciated.

Ok. Anyone see what I did wrong in the code above? I just found it. ? should be an &. Works now.
For future reference, it looks like this is about the simplest way I can think of to pass a variable to a page. Other form post/get or session based methods seem to be more complex.
$wh = $_GET['wh'];
beyond it being completely insecure?

My objective is to show content of external database on a wordpress page.
I have created a page template that includes php and an sql query that will query a non wordpress database on the fly. I wish to control the ouput of this page by getting a variable from the url.
For example a url linking to this page may look like this:
http://myblog.com?merchant=xyz
I would then like to grab the "merchant" variable and insert into the sql code on the page template.
I have tried
WHERE merchant = '<?php echo $_GET["$merchant"]; ?>'
without success
Are there any suggestions?
Many thanks in advance

In case it helps anyone else like me with little coding knowledge I achieved my objective by defining the variable using
$q = (isset($_GET["q"])
where q is the merchant defined in the url
The sql simply included the command WHERE merchant = '$q'
