Ecshop商品属性排序的问题和解决方法

里奥模板中心技术为您整理，Ecshop商品属性排序问题的解决方法。

情况一：添加新产品时，让属性按照添加的顺序（属性id）排列

修改/inclues/lib_goods.php

    /* 获得商品的规格 */
    $sql = "SELECT a.attr_id, a.attr_name, a.attr_group, a.is_linked, a.attr_type, ".
                "g.goods_attr_id, g.attr_value, g.attr_price " .
            'FROM ' . $GLOBALS['ecs']->table('goods_attr') . ' AS g ' .
            'LEFT JOIN ' . $GLOBALS['ecs']->table('attribute') . ' AS a ON a.attr_id = g.attr_id ' .
            "WHERE g.goods_id = '$goods_id' " .
            'ORDER BY g.goods_attr_id, a.sort_order, g.attr_price';
    $res = $GLOBALS['db']->getAll($sql);

情况二：在复制商品时属性排序跟原商品相反到处理
修改/inclues/lib_goods.php
/**
* 取得商品属性
* @param   int     $goods_id   商品id
* @return  array
*/
function get_goods_attr($goods_id)
{
    $attr_list = array();
    $sql = "SELECT a.attr_id, a.attr_name " .
            "FROM " . $GLOBALS['ecs']->table('goods') . " AS g, " . $GLOBALS['ecs']->table('attribute') . " AS a " .
            "WHERE g.goods_id = '$goods_id' " .
            "AND g.goods_type = a.cat_id " .
            "AND a.attr_type = 1".' ORDER BY a.attr_id';
    $attr_id_list = $GLOBALS['db']->getCol($sql);
    $res = $GLOBALS['db']->query($sql);
    while ($attr = $GLOBALS['db']->fetchRow($res))
    {
        if (defined('ECS_ADMIN'))
        {
            $attr['goods_attr_list'] = array(0 => $GLOBALS['_LANG']['select_please']);
        }
        else
        {
            $attr['goods_attr_list'] = array();
        }
        $attr_list[$attr['attr_id']] = $attr;
    }
    $sql = "SELECT attr_id, goods_attr_id, attr_value " .
            "FROM " . $GLOBALS['ecs']->table('goods_attr') .
            " WHERE goods_id = '$goods_id' " .
            "AND attr_id " . db_create_in($attr_id_list).' ORDER BY goods_attr_id';
    $res = $GLOBALS['db']->query($sql);
    while ($goods_attr = $GLOBALS['db']->fetchRow($res))
    {
        $attr_list[$goods_attr['attr_id']]['goods_attr_list'][$goods_attr['goods_attr_id']] = $goods_attr['attr_value'];
    }
    return $attr_list;
}

补充：上面说的是同一属性里属性值的排序
