我们会看到很多的网站可以看到有分类并且可以显示当前分类有多少商品数量了,下面我来给大家介绍实现方法.

非常简单的改动

1、includes/lib_goods.php下,找到这两个函数改成我这样就行,代码如下:

function get_categories_tree($cat_id = 0)

function get_child_tree($tree_id = 0)

/**

* 获得指定分类同级的所有分类以及该分类下的子分类

*

* @access  public

* @param   integer     $cat_id     分类编号

* @return  array

*/

function get_categories_tree($cat_id = 0)

{

    if ($cat_id > 0)

    {

        $sql = 'SELECT parent_id FROM ' . $GLOBALS['ecs']->table('category') . " WHERE cat_id = '$cat_id'";

        $parent_id = $GLOBALS['db']->getOne($sql);

    }

    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 ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$parent_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 cat_id,cat_name ,parent_id,is_show ' .

                'FROM ' . $GLOBALS['ecs']->table('category') .

                "WHERE parent_id = '$parent_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";

        $res = $GLOBALS['db']->getAll($sql);

        foreach ($res AS $row)

        {

            if ($row['is_show'])

            {

                /*获得分类下商品总数雕鹰团队：QQ284265134 */

                $children = get_children($row['cat_id']);

                $sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.

                'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.

                 'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';

                $cat_goods_num=$GLOBALS['db']->getOne($sql);

                $cat_arr[$row['cat_id']]['goods_num']   = $cat_goods_num == '' ? 0 : $cat_goods_num;



                $cat_arr[$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 (isset($row['cat_id']) != NULL)

                {

                    $cat_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);

                }

            }

        }

    }

    if(isset($cat_arr))

    {

        return $cat_arr;

    }

}

function get_child_tree($tree_id = 0)

{

    $three_arr = array();

    $sql = 'SELECT count(*) FROM ' . $GLOBALS['ecs']->table('category') . " WHERE parent_id = '$tree_id' AND is_show = 1 ";

    if ($GLOBALS['db']->getOne($sql) || $tree_id == 0)

    {

        $child_sql = 'SELECT cat_id, cat_name, parent_id, is_show ' .

                'FROM ' . $GLOBALS['ecs']->table('category') .

                "WHERE parent_id = '$tree_id' AND is_show = 1 ORDER BY sort_order ASC, cat_id ASC";

        $res = $GLOBALS['db']->getAll($child_sql);

        foreach ($res AS $row)

        {

                /*获得分类下商品总数雕鹰团队：QQ284265134 */

                $children = get_children($row['cat_id']);

                $sql = 'SELECT count(*)' . "FROM " . $GLOBALS['ecs']->table('goods') . ' AS g '.

                'WHERE g.is_on_sale = 1 AND g.is_alone_sale = 1 AND '.

                 'g.is_delete = 0 AND (' . $children . 'OR ' . get_extension_goods($children) . ') ';

                $cat_goods_num=$GLOBALS['db']->getOne($sql);

                $three_arr[$row['cat_id']]['goods_num']   = $cat_goods_num == '' ? 0 : $cat_goods_num;



            if ($row['is_show'])

               $three_arr[$row['cat_id']]['id']   = $row['cat_id'];

               $three_arr[$row['cat_id']]['name'] = $row['cat_name'];

               $three_arr[$row['cat_id']]['url']  = build_uri('category', array('cid' => $row['cat_id']), $row['cat_name']);

               if (isset($row['cat_id']) != NULL)

                   {

                       $three_arr[$row['cat_id']]['cat_id'] = get_child_tree($row['cat_id']);  //开源软件:phpfensi.com

            }

        }

    }

    return $three_arr;

}

注意这里:原版的lefttime.js是定义的单个ID

<font id="leftTime" class="f1"> 这里循环了,ID重复一定报错,这里怎么解决呢？你可以自己从JS文件夹里新复制一个lefttime.js这里我命名为:lefttime1.js；调用如下代码:

<script type="text/javascript" src="js/lefttime1.js"></script>

<meta http-equiv="Content-Type" content="text/html; charset=gbk">

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