在商品详细页,随机显示一定数量的同类产品

很多朋友安装相关产品模块,相关产品设置起来比较麻烦  
发布一个,在商品详细页,随机显示一定数量的同类产品,不需要任何设置   
有利于搜索引擎对网站的收录   
对优化会有好处

此模块取自lightinthebox

1, 创建一个新文件 随意命名 没重复就行 例如:tpl_product_info_similar.php  
复制该文件到includes\templates\你的模板\templates\目录下   
打开该文件,把以下代码复制进去并保存

代码: 全选<div id="similar_product">      
<h2>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 $i;?>" style="display:block;float:left;padding-left:10px;width:22%;">       
<a href="<?php echo zen_href_link(zen_get_info_page($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="<?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?>"><?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>

2,找到includes\templates\你的模板\templates\tpl_product_info_display.php文件  
在相应的位置加上以下代码:   
<?php require($template->get_template_dir(‘你创建的文件 tpl_product_info_similar.php’,DIR_WS_TEMPLATE, $current_page_base,’templates’). ‘/你创建的文件tpl_product_info_similar.php’); ?>

一般可以加到<?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’);?>的上面或下面
