ECShop 分类筛选（多重筛选）

1.分类筛选

category.dwt 中添加的代码需要自己根据模板需要添加css，选中栏目的背景颜色设置下span标签的底色就可以了演示效果

步骤如下一、category.php中添加代码:

//当前二级分类
$smarty->assign('categories1',    get_categories(get_parent($cat_id)));
$smarty->assign('parent_id',   get_parent($cat_id));//顶级分类id
/*获取顶级id*/
function get_parent($value,$id='')
{

    if($value!=0)
    {
$sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$value'";
$res = $GLOBALS['db']->getOne($sql);
return get_parent($res,$value);
    }
else
{
return $id;
}
}

/*提取二级分类*/
function get_categories($cat_id = 0)
{
    if ($cat_id > 0)
    {
$parent_id = $cat_id;
    }
    else
    {
        $parent_id = 0;
    }

    /*
     判断当前分类中全是是否是底级分类，
     如果是取出底级分类上级分类，
     如果不是取当前分类及其下的子分类
    */
    $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$cat_id' AND is_show = 1 ";
    if ($GLOBALS['db']->getOne($sql) || $parent_id == 0)
    {
        /* 获取当前分类及其子分类 */
        $sql = 'SELECT a.cat_id, a.cat_name, a.sort_order AS parent_order, a.cat_id, a.is_show,' .
                    'b.cat_id AS child_id, b.cat_name AS child_name, b.sort_order AS child_order ' .
                'FROM ' . $GLOBALS['ecs']->table('category') . ' AS a ' .
                'LEFT JOIN ' . $GLOBALS['ecs']->table('category') . ' AS b ON b.parent_id = a.cat_id AND b.is_show = 1 ' .
                "WHERE a.parent_id = '$parent_id' ORDER BY parent_order ASC, a.cat_id ASC, child_order ASC";
    }
    else
    {
        /* 获取当前分类及其父分类 */
        $sql = 'SELECT a.cat_id, a.cat_name, b.cat_id AS child_id, b.cat_name AS child_name, b.sort_order, b.is_show ' .
                'FROM ' . $GLOBALS['ecs']->table('category') . ' AS a ' .
                'LEFT JOIN ' . $GLOBALS['ecs']->table('category') . ' AS b ON b.parent_id = a.cat_id AND b.is_show = 1 ' .
                "WHERE b.parent_id = '$parent_id' ORDER BY sort_order ASC";
    }
    $res = $GLOBALS['db']->getAll($sql);

    $cat_arr = array();
    foreach ($res AS $row)
    {
        if ($row['is_show'])
        {
            $cat_arr[$row['cat_id']]['id']   = $row['cat_id'];
            $cat_arr[$row['cat_id']]['name'] = $row['cat_name'];
            $cat_arr[$row['cat_id']]['url']  = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);

            if ($row['child_id'] != NULL)
            {
                $cat_arr[$row['cat_id']]['children'][$row['child_id']]['id']   = $row['child_id'];
                $cat_arr[$row['cat_id']]['children'][$row['child_id']]['name'] = $row['child_name'];
                $cat_arr[$row['cat_id']]['children'][$row['child_id']]['url']  = build_uri('category', array('cid' => $row['child_id']), $row['child_name']);
            }
        }
    }

    return $cat_arr;
}

二、category.dwt 中 合适的位置添加 代码：（这个需要注意，有的筛选是加载到lib文件里，自己根据自己的模板需求按位置添加）

<!--品牌 start-->
    <!--{if $categories1}-->
<div class="screeBox">
<strong>分类：</strong>
<!-- {if $parent_id==$category}-->
  <span>全部</span>
<!-- {else} -->
      <a href="category.php?id={$parent_id}">全部</a>
<!-- {/if} -->
<!--{foreach from=$categories1 item=cat}-->
<!-- {if $category==$cat.id} -->
   <span>{$cat.name}</span>
<!-- {else} -->
   <a href="{$cat.url}">{$cat.name}</a>
<!-- {/if} -->
<!--{/foreach}-->
</div>
<!--{/if}-->
<!--end-->

？添加代码结果无效？，这是由于在category.php中添加代码的时候位置不对，多试几个位置，我是添加到78行。这个位置以上的代码是

/*------------------------------------------------------ */
//-- INPUT
/*------------------------------------------------------ */

/* 获得请求的分类 ID */
if (isset($_REQUEST['id']))
{
    $cat_id = intval($_REQUEST['id']);
}
elseif (isset($_REQUEST['category']))
{
    $cat_id = intval($_REQUEST['category']);
}
else
{
    /* 如果分类ID为0，则返回首页 */
    ecs_header("Location: ./\n");

    exit;
}

可以对照一下

2.颜色筛选
牵涉到的修改文件
/admin/templates/goods_info.htm

/admin/goods.php

/goods.php

修改步骤:
1:后台运行sql语句,admin后台->左侧导航->数据库管理->SQL查询

运行下面的语句(只能运行一次,小心):
alter table ecs_goods add seo_title text not null

2:修改 admin/templates/goods_info.htm
在此文件的第44行后面,加上下面几行

          <tr>
            <td class="label">自定义title</td>
            <td>
              <input type="text" name="seo_title" value="{$goods.seo_title}" size="30" />
            </td>
          </tr>

3:修改admin/goods.php
第765行

"is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type, rank_integral)" .

修改为:
"is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type, rank_integral,seo_title)" .

复制代码
第771行,

" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$rank_integral')";

修改为

" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$rank_integral','$_POST[seo_title]')";

第779行

"is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type, extension_code, rank_integral)" .

修改为:

"is_on_sale, is_alone_sale, goods_desc, add_time, last_update, goods_type, extension_code, rank_integral,seo_title)" .

第785行

" '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$code', '$rank_integral')";

修改为:

 " '$_POST[goods_desc]', '" . gmtime() . "', '". gmtime() ."', '$goods_type', '$code', '$rank_integral','$_POST[seo_title]')";

第817行:

"promote_end_date = '$promote_end_date', ";

修改为:

"seo_title = '$_POST[seo_title]', ";```

4:修改/goods.php的第161行为: 

$smarty->assign('page_title', trim($goods['seo_title'])?$goods['seo_title']:$position['title']); // 页面标题

清除缓存

测试：
编辑商品或添加商品 -> 自定义Title

完成
