ecshop增加已售数量和评论数量很简单，步骤如下：
1.在ecshop程序goods.php页面最下面加入这两个函数
function get_buy_sum(ParseError: KaTeX parse error: Expected '}', got 'EOF' at end of input: goods_id)
{sql = 'SELECT IFNULL(SUM(g.goods_number), 0) ' .
'FROM ' . GLOBALS[′ecs′]−>table(′orderinfo′).′ASo,′.GLOBALS['ecs']->table('order_info') . ' AS o, ' .GLOBALS[′ecs′]−>table(′orderinfo′).′ASo,′.GLOBALS['ecs']->table('order_goods') . ' AS g ' .
"WHERE o.order_id = g.order_id " .
"AND o.order_status = '" . OS_CONFIRMED . "' " .
"AND o.shipping_status " . db_create_in(array(SS_SHIPPED, SS_RECEIVED)) .
" AND o.pay_status " . db_create_in(array(PS_PAYED, PS_PAYING)) .
" AND g.goods_id = 'goodsid′";returngoods_id'";
returngoodsid′";returnGLOBALS['db']->getOne(ParseError: KaTeX parse error: Expected 'EOF', got '}' at position 7: sql);
}̲
function get_…goods_id) {
sql="selectcount(∗)from".sql= "select count(*) from ".sql="selectcount(∗)from".GLOBALS['ecs']->table('comment')." where id_value='".goodsid."′ANDstatus=1";returngoods_id."' AND status = 1";
returngoodsid."′ANDstatus=1";returnGLOBALS['db']->getOne($sql);
}
2.在ecshop程序goods.php中加入
在代码：
$smarty->display(‘goods.dwt’, $cache_id);
的前面，加入如下代码：
$smarty->assign('buy_num',get_buy_sum($goods_id));
$smarty->assign('comment_num',get_comment_num($goods_id));
3.ecshop中goods.dwt模板中加入如下代码：
<!-- {if ParseError: KaTeX parse error: Expected 'EOF', got '}' at position 8: buy_num}̲ 已出售量-->
buy_num}
</dd>
</li>
<!--{/if}-->
<!-- {if ParseError: KaTeX parse error: Expected 'EOF', got '}' at position 12: comment_num}̲ 评论数量-->
comment_num}</a>
</dd>
</li>
<!--{/if}-->
