show zencart categories/products in WordPress main or sidebar

After days of intensive searching I have only found one website offering a solution to displaying Zencart items inside a WordPress page.

I don’t want to use the WordPress on Zencart plugin. I want an existing WordPress website, which is used as a CMS, to display some or all of the products available in the Zen Cart shop.

I found a possible solution here, I can’t get it working but I think it is possibly a simple problem to do with the ‘DEFINE’.

I’m hoping someone here can explain the links needed in the DEFINEs- I & 2 others get the same error message “Parse error: syntax error, unexpected ‘:’ in /home/noah/public_html/blog/wp-content/plugins/zencat/zencat.php on line 13”

Line 13 is the either the third or 4th DEFINE

“define(‘DIR_WS_CATALOG’, ‘/~lsenft/zencart/’);
define(‘HTTP_SERVER’, ‘http://localhost’);”

My WordPress installation is in public_html and Zencart is in public_html/shop – what should I put in the defines?

Below is the entire code which when saved in the plugins folder as a php file creates a plugin called Products

<?php
/*
Plugin Name: Products
Plugin URI: http://www.levisenft.com/
Description: Zen Cart Categories
Author: Levi Senft
Version: 1

define(‘TABLE_CATEGORIES’, ‘zen_categories’);
define(‘TABLE_CATEGORIES_DESCRIPTION’, ‘zen_categories_description’);
define(‘DIR_WS_CATALOG’, ‘/~lsenft/zencart/’);
define(‘HTTP_SERVER’, ‘http://localhost’);

function zen_cat() {
    echo ‘<li class="widget widget_zen_cat"><h2 class="widgettitle">Products</h2><ul>’;
    $categories_query = "select c.categories_id, cd.categories_name, c.parent_id, c.categories_image
        from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
        where c.parent_id = 0
        and c.categories_id = cd.categories_id
        and c.categories_status= 1
        order by sort_order, cd.categories_name";
    $results = mysql_query($categories_query);
    $item_count = 1;

    while($row = mysql_fetch_assoc($results)) {
        echo ‘<li class="zen_cat_item zen-cat-item-’ . $item_count . ‘"><a href="’ . HTTP_SERVER . DIR_WS_CATALOG . ‘index.php?main_page=index&cPath=’ . $row['categories_id'] . ‘">’ . $row['categories_name'] . ‘</a>’;

        $subcats_query = "select c.categories_id, cd.categories_name, c.parent_id, c.categories_image
            from " . TABLE_CATEGORIES . " c, " . TABLE_CATEGORIES_DESCRIPTION . " cd
            where c.parent_id = " . $row['categories_id'] . "
            and c.categories_id = cd.categories_id
            and c.categories_status= 1
            order by sort_order, cd.categories_name";

        $subcats_results = mysql_query($subcats_query);

        if (mysql_num_rows($subcats_results) > 0) {
            $subitem_count = 1;
            echo ‘<ul>’;
            while($subcats_row = mysql_fetch_assoc($subcats_results)) {
                echo ‘<li class="zen_cat_item zen-cat-item-’ . $subitem_count . ‘"><a href="’ . HTTP_SERVER . DIR_WS_CATALOG . ‘index.php?main_page=index&cPath=’ . $row['categories_id'] . ‘_’ . $subcats_row['categories_id'] . ‘">’ . $subcats_row['categories_name'] . ‘</a>’;
                $subitem_count++;
            }
            echo ‘</ul>’;
        }
        echo ‘</li>’;
        $item_count++;
    }

    echo ‘</ul></li>’;
