PHP WordPress, WP_Query custom attributes

Hello all,
It’s been a while since I have been on here and I am glad y’all are still going strong. I still see NogDog is here and he has helped me so freaking much in the past! AWESOME!
`
Anyways, I am passing a variable via the URL and have had no problem. However, the variable is being passed to a page template called ‘product’ which displays a single product out of a catalog. The variable being passed is the slug name of the product that was selected from the catalog.

My catalog is a widget I developed to display a gallery of my products and also their custom fields which can be changed within the widget area. ANYWAYS, this is NOT a POST so I can’t use the get_post() approach! I need to query one particular product out of my catalog and it’s attributes so I can display it singularly on a page.

ESSENTIALLY:
When viewer clicks product from a catalog, site sends the slug name of that product via the URL to the product page ([url]http://localhost:8888/wordpress/product/?id=my-product-name[/url]). Now I need to query my products in the catalog (not a post) and find “my-product-name” under my custom slug field I created in each item.

My code for the product page:

[CODE]
<?php
if(isset($wp_query->query_vars[‘id’])) {
$product = urldecode($wp_query->query_vars[‘id’]);
}

echo $product;
?>

<div class=”grid-catalog”>
<div class=”site-catalog”>
<ul>
<!– CATALOG –>
<?php
if( dynamic_sidebar(‘catalog’)) : else : endif;
?>
</ul>
</div>
</div>
?>
[/CODE]

As of now, this doesn’t do anything but take you to the products page and show you the entire catalog just as you were looking at on the previous page. My goal is to query this catalog and display only the product that is in the URL variable.

Anyways, here is my catalog plugin/widget code:
