Howto Add class=selected to curent product image in sidebox when on product info page

[DrByte]

Try this ...
(And of course you'll still need to add your .selectedImg selector to your stylesheet.)

<?php
/**
 * Product Listing Sidebox
 *
 */

  $content = '';
  $content .= '<div id="' . str_replace('_', '-', $box_id . 'Content') . '" class="sideBoxContent">';
    
    $prolist_query = "select 

            products.products_image, products_description.products_name, products_to_categories.*, categories_description.categories_id
            
            from products, products_description, products_to_categories, categories_description
            
            where categories_description.categories_id = '$current_category_id'
            and categories_description.categories_id = products_to_categories.categories_id
            and products_description.products_id = products_to_categories.products_id
            and products.products_id = products_description.products_id
            
            order by products_description.products_name
            ";
    
        $prolist = $db->Execute($prolist_query);
        
     while (!$prolist->EOF) {
       $classHref = ($prolist->fields['products_id'] == $_GET['products_id']) ? ' class="selectedImg"' : '';
       $classImg = ($prolist->fields['products_id'] == $_GET['products_id']) ? ' selectedImg' : '';
       $content .=  '<a' . $classHref . ' href="' . zen_href_link(zen_get_info_page($prolist->fields['products_id']), ($_GET['cPath'] > 0 ? 'cPath=' . $_GET['cPath'] . '&' : '') . 'products_id=' . $prolist->fields['products_id']) . '">' . zen_image(DIR_WS_IMAGES . $prolist->fields['products_image'], $prolist->fields['products_name'],SMALL_IMAGE_WIDTH*1.2, SMALL_IMAGE_HEIGHT*1.2, 'class="listingProductImage' . $classImg . ' "') . '</a>';
       $prolist->MoveNext();
   };
    
  $content .= '</div>';
