ecshop教程：ECSHOP商品关键词模糊分词搜索插件,商品列表关键字加红功能

最近给客户做一个ECSHOP商城，发现ECSHOP的模糊搜索要求太高，需要加入and、空格、加号等，客户搜索的时候不可能这样操作。

考虑到工期的问题，采用了织梦的分词算法，搜索效果虽然不是特别理想，但是这么短的时间也只能这样了。

在此分享给没钱又着急的朋友，需要用到的文件在文章末尾提供下载，大家下载后也可以直接覆盖使用。

一、ECSHOP联想下拉框

1、修改page_header.lbi模版文件，将搜索文本框修改为：

<input name="keywords" type="text" id="keyword" value="ecshop" 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

嵌入css文件

2、根目录添加php文件search_suggest.php文件

二、分词搜索

ECSHOP教程根目录增加织梦分词算法函数和词库：lib_splitword_full.php和dededic.csv

1、修改search.php文件第196行

/* 检查关键字中是否有空格，如果存在就是并 */

$arr = explode(' ', $_REQUEST['keywords']); $operator = " AND ";

改为：

/*调用织梦分词功能-start*/

require("lib_splitword_full.php"); $sp = new SplitWord(); $fenci=$sp->SplitRMM($_REQUEST['keywords']); $sp->Clear(); /* 织梦分词后是使用空格进行划分，所以仍可使用ecshop的按照空格拆分为数组功能：检查关键字中是否有空格，如果存在就是并 */

$arr = explode(' ', $fenci); $arr = array_reverse($arr);//将数组倒序排列，并插入完整关键字到数组末尾

$arr[count($arr)]=$_REQUEST['keywords']; $arr = array_reverse($arr);//再次将数组倒序，使完整关键字可以第一个被检索

array_pop($arr);//删除织梦分词产生的数组最后一个元素为空格

$operator = " and ";//sql检索语句使用union联合检索

$piaohong = $arr;//$arr数组在飘红的时候已经被产品列表占用了，所以另外赋值给一个数组备用。

/*调用织梦分词功能-end*/

2、修改search.php文件第382行到403行

/* 获得符合条件的商品总数 */

$sql = "SELECT COUNT(*) FROM " .$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; } /* 查询商品 */

$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";

打开 /includes/lib_goods.php 文件（建议使用editplus）找到下面代码（大概在287行左右）

/*sun04zh3-20130905-调用织梦分词功能-更改ecshop的sql语句采用union方式-start*/

/*因为后面要用union生成数据集表，所以先根据拆分出的关键词，生成union所需的所有sql语句，*/

$select = "("; foreach($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";//第一个关键词是完整关键词

if($se==0)//插入一个当所有拆分关键词在商品名称中为and时的sql语句

{ $select .= " UNION SELECT click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type FROM(select click_count,goods_sn,is_alone_sale,is_on_sale,is_delete,goods_id, goods_name, market_price, is_new, is_best, is_hot, shop_price AS org_price, shop_price ,promote_price, promote_start_date, promote_end_date, goods_thumb, goods_img, goods_brief, goods_type from".$ecs->table('goods')." where 1 $keywords order by click_count desc) AS Pa"; } if($se<count($arr)-1)//在每条select语句后增加union，最后一个不加，所以$se小于元素数量-1

{ $select.=" UNION "; } } $select.=")"; if($select=="()")//当关键词为空时，没有拆分关键词，所以用于union的$select为空，仍需要调用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 { /* 获得符合条件的商品总数 */

$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=="()")//当关键词为空时，没有拆分关键词，所以用于union的$select为空，仍需要调用goods表

{ /* 查询商品 */

$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 { /* 查询商品 */

"FROM $select AS P " .

"WHERE is_delete = 0 AND is_on_sale = 1 AND is_alone_sale = 1 " ; }

三、搜索出的产品列表产品关键词飘红功能：

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']; }

修改为：

/*根据分词对产品名称进行替换-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'];//因为前台用到没有替换的商品名称，所以保留goods_name值

$arr[$row['goods_id']]['tihuan'] = $tihuan; /*根据分词对产品名称进行替换-end*/

2、修改search.dwt模板文件

将显示商品名称的地方替换为：

<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
