原文地址：http://www.fuyahui.com/zencart-add-popular-search.html

--------------------------------------------------------------------------

第一步执行数据库，代码如下

SET SQL_MODE="NO_AUTO_VALUE_ON_ZERO";
/*!40101 SET @OLD_CHARACTER_SET_CLIENT=@@CHARACTER_SET_CLIENT */;
/*!40101 SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
/*!40101 SET @OLD_COLLATION_CONNECTION=@@COLLATION_CONNECTION */;
/*!40101 SET NAMES utf8 */;
CREATE TABLE IF NOT EXISTS `customers_searches` (`search` varchar(255) NOT NULL DEFAULT '',
`language_id` int(11) unsigned DEFAULT NULL,`freq` tinyint(3) unsigned DEFAULT '0',PRIMARY KEY (`search`) USING BTREE,
KEY `lang` (`language_id`))ENGINE=MyISAM DEFAULT CHARSET=utf8;

第二步修改文件includes\modules\pages\advanced_search_result\header_php.php，也可以修改includes\application_bottom.php增加如下代码

/* 数据库中表customers_searches增加搜索次数和关键词*/
if ($_GET['keyword'] != '') {
$search_count = $db->Execute("select freq from customers_searches where search = '". $_GET['keyword'] . "'");
if (!$search_count->RecordCount()) {
$db->Execute("insert into customers_searches (search,language_id, freq) values
('". $_GET['keyword'] ."','". $_SESSION['languages_id'] ."',1)");
} else {
$db->Execute("update customers_searches set freq =
" . ($search_count->fields['freq']+1) . " where search = '". $_GET['keyword'] . "'");
}

第三步增加一个文件includes\modules\sideboxes\你自己的模板名称\popular_searches.php  代码如下  可以根据自己的需求进行修改。

<div id="information" style="width: 170px">
<div>
<h3 id="informationHeading"><?php echo TEXT_BOX_POPULAR_SEARCHES;?></h3>
</div>
<div id="informationContent">
<ul style="margin: 0; padding: 0; list-style-type: none;">
<?php$popularSearches = $db->Execute('select search,freq from customers_searches limit 12');
$popularContent_i = 0;while(!$popularSearches->EOF){$popularContent ='';
$popularContent .= '<a href="'.zen_href_link(FILENAME_ADVANCED_SEARCH_RESULT,
'keyword='.$popularSearches->fields['search'], 'NONSSL').'" _fcksavedurl="'.
zen_href_link(FILENAME_ADVANCED_SEARCH_RESULT,'keyword='.$popularSearches->fields['search'], 'NONSSL').'">';
if($popularSearches->fields['freq'] >10){$popularContent .= '<strong style="color:red;">';
}$popularContent .= $popularSearches->fields['search'];
if($popularSearches->fields['freq']>10){$popularContent .= '</strong>';}$popularContent .= '</a>';
if($popularContent_i < $popularSearches->RecordCount()){$popularContent .= ', ';
$popularContent_i++;}echo $popularContent;$popularSearches->MoveNext();}?>
</ul>
</div>
</div>

第四步在includes\languages\english.php中添加如下文字

define('TEXT_BOX_POPULAR_SEARCHES','Popular Searches');
