ECSHOP模糊分詞搜索和商品列表關鍵字飄紅功能

最近在用ECSHOP做一個商城，發現ECSHOP的模糊搜索要求太高，需要加入and、空格、加號等，客戶搜索的時候不可能這樣操作。所以想對搜索功能進行改進，可是在網上沒有找到這樣的插件，有收費的，結果要2000大元。考慮了一下申請經費的麻煩，自己費點兒力氣做一個吧。

考慮到工期的問題，采用了織夢的分詞算法，搜索效果雖然不是特別理想，但是這么短的時間也只能這樣了。

在此分享給沒錢又着急的朋友，需要用到的文件在文章末尾提供下載，大家下載后也可以直接覆蓋使用。

一、ECSHOP聯想下拉框

1、修改page_header.lbi模版文件，將搜索文本框修改為：

<input name="keywords" type="text" id="keyword" value="<!--{if ($search_keywords neq "")}{$search_keywords|escape}--><!--{else}-->ecshop<!--{/if}-->" class="search-input"  onfocus="if(this.value=='ecshop'){this.value='';this.style.color='#000';}"  onblur="closediv();if(this.value==''){this.value='ecshop';this.style.color='#999';}" style="color:#999;"  onkeyup="keyupdeal(event,this.value);" onkeydown="keydowndeal(event);" onclick="keyupdeal(event,this.value);"   autocomplete="off" />
   <div id="search_suggest" style="display:none;" onmouseover='javascript:_over();' onmouseout='javascript:_out();'></div>

嵌入js文件

<script type="text/javascript" src="/js/suggest.js"></script>

嵌入css文件

<link href="/themes/default/images/css.css" rel="stylesheet" type="text/css">

 2、根目錄添加php文件search_suggest.php文件

二、分詞搜索

根目錄增加織夢分詞算法函數和詞庫：lib_splitword_full.php和dededic.csv

1、修改search.php文件第196行

/* 檢查關鍵字中是否有空格，如果存在就是並 */
            $arr        = explode(' ', $_REQUEST['keywords']);
            $operator   = " AND ";

改為：

/*調用織夢分詞功能-start*/
            require("lib_splitword_full.php");
            $sp = new SplitWord();
            $fenci=$sp->SplitRMM($_REQUEST['keywords']);
            $sp->Clear();
            /* 織夢分詞后是使用空格進行划分，所以仍可使用ecshop的按照空格拆分為數組功能：檢查關鍵字中是否有空格，如果存在就是並 */
            $arr        = explode(' ', $fenci);
            $arr        = array_reverse($arr);//將數組倒序排列，並插入完整關鍵字到數組末尾
            $arr[count($arr)]=$_REQUEST['keywords'];
            $arr        = array_reverse($arr);//再次將數組倒序，使完整關鍵字可以第一個被檢索
            array_pop($arr);//刪除織夢分詞產生的數組最后一個元素為空格
            $operator   = " and ";//sql檢索語句使用union聯合檢索
            $piaohong = $arr;//$arr數組在飄紅的時候已經被產品列表占用了，所以另外賦值給一個數組備用。
            /*調用織夢分詞功能-end*/

2、修改search.php文件第382行到403行

 /* 獲得符合條件的商品總數 */
    $sql   = "SELECT COUNT(*) FROM " .$ecs->table('goods'). " AS g ".
        "WHERE g.is_delete = 0 AND g.is_on_sale = 1 AND g.is_alone_sale = 1 $attr_in ".
        "AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock ." ) ".$tag_where." )";
    $count = $db->getOne($sql);

    $max_page = ($count> 0) ? ceil($count / $size) : 1;
    if ($page > $max_page)
    {
        $page = $max_page;
    }

    /* 查詢商品 */
    $sql = "SELECT g.goods_id, g.goods_name, g.market_price, g.is_new, g.is_best, g.is_hot, g.shop_price AS org_price, ".
                "IFNULL(mp.user_price, g.shop_price * '$_SESSION[discount]') AS shop_price, ".
                "g.promote_price, g.promote_start_date, g.promote_end_date, g.goods_thumb, g.goods_img, g.goods_brief, g.goods_type ".
            "FROM " .$ecs->table('goods'). " AS g ".
            "LEFT JOIN " . $GLOBALS['ecs']->table('member_price') . " AS mp ".
                    "ON mp.goods_id = g.goods_id AND mp.user_rank = '$_SESSION[user_rank]' ".
            "WHERE g.is_delete = 0 AND g.is_on_sale = 1 AND g.is_alone_sale = 1 $attr_in ".
                "AND (( 1 " . $categories . $keywords . $brand . $min_price . $max_price . $intro . $outstock . " ) ".$tag_where." ) " .
            "ORDER BY $sort $order";

修改為：

/*sun04zh3-20130905-調用織夢分詞功能-更改ecshop的sql語句采用union方式-start*/
/*因為后面要用union生成數據集表，所以先根據拆分出的關鍵詞，生成union所需的所有sql語句，*/
$select = "(";
    foreach($arr AS $se => $t)
    {

        $select .= "SELECT click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type FROM(select  click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type from".$ecs->table('goods')." where goods_name like '%$t%' order by click_count desc) AS P$se";//第一個關鍵詞是完整關鍵詞
        if($se==0)//插入一個當所有拆分關鍵詞在商品名稱中為and時的sql語句
        {
            $select .= " UNION SELECT click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type FROM(select  click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type from".$ecs->table('goods')." where 1  $keywords order by click_count desc) AS Pa";
        }
        if($se<count($arr)-1)//在每條select語句后增加union，最后一個不加，所以$se小於元素數量-1
        {
            $select.=" UNION ";
        }
    }
    $select.=")";
    if($select=="()")//當關鍵詞為空時，沒有拆分關鍵詞，所以用於union的$select為空，仍需要調用goods表
    {
         $sql   = "SELECT COUNT(*) FROM ".$ecs->table("goods")." AS P " .
            "WHERE is_delete = 0 AND is_on_sale = 1 AND is_alone_sale = 1  " ;
    }
    else
    {
         /* 獲得符合條件的商品總數 */
        $sql   = "SELECT COUNT(*) FROM $select AS P " .
                "WHERE is_delete = 0 AND is_on_sale = 1 AND is_alone_sale = 1  " ;
    }
    $count = $db->getOne($sql);

    $max_page = ($count> 0) ? ceil($count / $size) : 1;
    if ($page > $max_page)
    {
        $page = $max_page;
    }
    if($select=="()")//當關鍵詞為空時，沒有拆分關鍵詞，所以用於union的$select為空，仍需要調用goods表 
    {
         /* 查詢商品 */
    $sql = "SELECT click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type ".
            "FROM ".$ecs->table("goods")." AS P " .
            "WHERE is_delete = 0 AND is_on_sale = 1 AND is_alone_sale = 1  " ;
    }
    else
    {
         /* 查詢商品 */
            $sql = "SELECT click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type ".
            "FROM $select AS P " .
            "WHERE is_delete = 0 AND is_on_sale = 1 AND is_alone_sale = 1  " ;
    }
   

三、搜索出的產品列表產品關鍵詞飄紅功能：

1、修改search.php文件第473行到480行

if($display == 'grid')
        {
            $arr[$row['goods_id']]['goods_name']    = $GLOBALS['_CFG']['goods_name_length'] > 0 ? sub_str($row['goods_name'], $GLOBALS['_CFG']['goods_name_length']) : $row['goods_name'];
        }
        else
        {
            $arr[$row['goods_id']]['goods_name'] = $row['goods_name'];
        }

修改為：

/*根據分詞對產品名稱進行替換-start*/
        $tihuan=$row["goods_name"];
        foreach($piaohong AS $ph_count => $ph)
        {

            $tihuan = str_replace($ph,"<b style='color:#d90000'>$ph</b>",$tihuan);
        }       
        $arr[$row['goods_id']]['goods_name'] = $row['goods_name'];//因為前台用到沒有替換的商品名稱，所以保留goods_name值
           $arr[$row['goods_id']]['tihuan'] = $tihuan;
        /*根據分詞對產品名稱進行替換-end*/

 2、修改search.dwt模板文件

將顯示商品名稱的地方替換為：

<p><a href="{$goods.url}" title="{$goods.name|escape:html}">{$goods.tihuan}</a></p>

 四、文中所有涉及的修改和要用到的文件，因為沒找到上傳文件的地方所有放到其他網站了。下載地址：http://download.csdn.net/detail/sun04zh3/6216851
