如何讓zencart的產品頁面顯示同類產品，最模板提供zencart教程：
首先找到zencart文件，在 includes/templates/你的模板目錄/templates/下面創建一個文件 命名為tpl_product_info_similar.php
當然，也可以隨便命名，把以下代碼復制進去，
<div class="centerBoxWrapper" id="similar_product">
<h2 class="centerBoxHeading">Related Products</h2>
<ul>
<?php
$products_id = (int)$_GET['products_id'];$flash_page_id_con = array();
$flash_page_images_con = array();
$flash_page_price_con = array();
$flash_page_name_con = array(); $flash_page_query = "select
p.products_id,p.products_image,pd.products_name from " . TABLE_PRODUCTS ." p, ".
TABLE_PRODUCTS_DESCRIPTION . " pd where p.`products_id`=pd.`products_id` AND
pd.`language_id` = '" . (int)$_SESSION['languages_id'] . "' AND p.`master_categories_id` =
" . zen_get_products_category_id($products_id) . " ORDER BY rand() limit 12";
$flash_page = $db->Execute($flash_page_query);
while(!$flash_page->EOF){
$flash_page_items[] = $flash_page->fields;
$flash_page_id_con[] = $flash_page->fields['products_id'];
$flash_page_images_src = is_int(strpos($flash_page->fields
['products_image'],','))? substr($flash_page->fields['products_image'],0,strpos
($flash_page->fields['products_image'],',')):$flash_page->fields['products_image'];
$flash_page_images_con[] = '"'.(zen_not_null($flash_page->fields
['products_image']) ? $flash_page_images_src : PRODUCTS_IMAGE_NO_IMAGE ).'"';
$flash_page_price_con[] = '"'.$currencies->display_price
(zen_get_products_base_price($flash_page->fields['products_id']),zen_get_tax_rate
($product_check->fields['products_tax_class_id'])).'"';
$flash_page_name_con[] = '"'.zen_output_string(zen_get_products_name
($flash_page->fields['products_id'])).'"';
$flash_page->MoveNext();
}
$flash_page_id = implode(",", $flash_page_id_con);
$flash_page_images = implode(",", $flash_page_images_con);
$flash_page_price = implode(",", $flash_page_price_con)
$flash_page_name = implode(",", $flash_page_name_con);
$flash_page_display_num = $flash_page->RecordCount();
?>
<?php for($i = 0; $i< $flash_page_display_num ; $i++){?>
<li id="li<?php echo $i;?>" style="display:block;float:left;padding-
left:10px;width:160px; height:160px;">
<a href="http://taoge167.blog.163.com/blog/<?php echo zen_href_link(zen_get_info_page($flash_page_items[$i]
['products_id']), 'products_id=' . $flash_page_items[$i]['products_id']);?>"><?php echo
zen_image(DIR_WS_IMAGES . $flash_page_items[$i]['products_image'], $flash_page_items[$i]
['products_name'], IMAGE_FEATURED_PRODUCTS_LISTING_WIDTH,
IMAGE_FEATURED_PRODUCTS_LISTING_HEIGHT); ?></a><p style="text-align:center;"><a href="http://taoge167.blog.163.com/blog/<?php
echo zen_href_link(zen_get_info_page($flash_page_items[$i]['products_id']), 'products_id='
. $flash_page_items[$i]['products_id']);?>"><?php echo $flash_page_items[$i]
['products_name']; ?></a><br /><strong id="cell_price<?php echo $i?>" class="red"><?php
echo $currencies->display_price((zen_get_products_base_price($flash_page_items[$i]
['products_id']) == 0 ? zen_get_products_sample_price($flash_page_items[$i]
['products_id']): zen_get_products_base_price($flash_page_items[$i]
['products_id'])),zen_get_tax_rate($product_check->fields['products_tax_class_id'])); ?></strong></p>
</li>
<?php
//print_r($flash_page_items[$i]);
}
?>
</ul>
</div>
<div style="clear:both; height:1px;"/>
然后，在zen-cart模板目錄中的includes/templates/你的模板目錄/templates/tpl_product_info_display.php 中 修改一些內容
找到 <!–bof also purchased products module–>
<?php require($template->get_template_dir('tpl_modules_also_purchased_products.php', DIR_WS_TEMPLATE, $current_page_base,'templates'). '/' . 'tpl_modules_also_purchased_products.php');?>
<!–eof also purchased products module–>
在他的后面添加
<!–bof similar products–>
<?php require($template->get_template_dir('tpl_product_info_similar.php', DIR_WS_TEMPLATE, $current_page_base,'templates'). '/' . 'tpl_product_info_similar.php');?>
<!–eof similar products–>
這樣，就可以實現在zencart模板中的產品詳細頁顯示同類的產品，以增加搜索引擎收錄，有益于zencart的seo優化了。
