If your WP Page always expects the same aStore variables you could simply echo the args right into the iframe tag’s src:

http://astore.amazon.com/affiliateID?<?php echo $_GET['varname'] . '&#038;' . $_GET['a'] . '&#038;' . $_GET['b']; ?>

The echo statement writes out the values of ‘varname’, ‘a’, and ‘b’ with an ampersand in between each argument.

I need to generate a similar affiliate URL that contains multiple fields after the “?”. Something like: http://astore.amazon.com/affiliateID?azdp=0123456789&a=1111&b=2222

My question is what the php code would be to also GET the “a=” and “b=” into the URL? I am not sure what the correct syntax for that would be in PHP.

I have to define these different parts of the URL in here I guess;

if (isset($_GET['slp'])) {
$dp = $_GET['slp'];

Many thanks!

Are all of your aStore clicks showing up in your full summary page? I’ve got a few random Amazon widgets in blog posts and clicks on those are all showing up just fine in the summary, but it doesn’t appear that aStore clicks are showing up (certainly I have been clicking on things a ton as I tweak the design and inventory). Just want to make sure I am receiving commission for anything I ship. I sent Amazon an e-mail a few minutes ago and will let you know what I hear.

You can add another parameter to the script, as shown below. There should be no line breaks in the echo statements. If you copy the code and paste to a text editor, the lines will be written properly.

I’m glad your question caused me to go look at the store page because the custom page template got trashed in one of my theme upgrades. I redid an AStore page template and inserted the following code (with my own AffiliateID) as the first thing in the WP loop:

<?php
if (isset($_GET['azdp'])) {
$dp = $_GET['azdp'];
echo "<iframe src='http://astore.amazon.com/AffiliateID/detail/$dp' width='100%' height='1200' frameborder='0'></iframe>";}
else if (isset($_GET['azcat'])) {
$cat = $_GET['azcat'];
echo "<iframe src='http://astore.amazon.com/AffiliateID?_encoding=UTF8&#038;node=$cat' width='100%' height='1200' frameborder='0'></iframe>";
} else {
echo "<iframe src='http://astore.amazon.com/AffiliateID' width='100%' height='1200' frameborder='0'></iframe>";}
?>

To load the Black Tea category as the aStore iframe src, I would use this link:
Black Tea

The code could be made more efficient, but it will work and is understandable.

Blogger is not as versatile as WordPress, but is tolerant of Adsense and Amazon ads, so that’s a possibility if you need free hosting.
