实现ecshop商品详细页尺码颜色选择并关联显示库存

ecshop服装商城很多都十分需要一个颜色尺码的功能，其实在淘宝，凡客上都类似的功能，客户在下单时选容易选择相应的颜色尺码，其实ecshop要实现这样的功能并不难，因为ecshop是开源免费的

效果如下：

goods.dwt修改如何下：

{$value.label}

在显示详细信息合适的地方加

（库存：{$goods.goods_number} {$goods.measure_unit}）

在goods.dwt加js代码:

function changeAtt(t,a,goods_id) {

t.lastChild.checked='checked';

for (var i = 0; i

if (t.parentNode.childNodes[i].className == 'cattsel') {

t.parentNode.childNodes[i].className = '';

}

}

t.className = "cattsel";

var formBuy = document.forms['ECS_FORMBUY'];

spec_arr = getSelectedAttributes(formBuy);

Ajax.call('goods.php?act=get_products_info', 'id=' + spec_arr+ '&goods_id=' + goods_id, shows_number, 'GET', 'JSON');

changePrice();

}

function shows_number(result)

{

if(result.product_number !=undefined)

{

$('shows_number').innerHTML = result.product_number+'件';

}

else

{

$('shows_number').innerHTML = '未设置'

}

}

打开goods.php添加70行左右吧

if (!empty($_REQUEST['act']) && $_REQUEST['act'] == 'get_products_info')

{

include('includes/cls_json.php');

$json = new JSON;

// $res = array('err_msg' => '', 'result' => '', 'qty' => 1);

$spce_id = $_GET['id'];

$goods_id = $_GET['goods_id'];

$row = get_products_info($goods_id,explode(",",$spce_id));

//$res = array('err_msg'=>$goods_id,'id'=>$spce_id);

die($json->encode($row));

}

通过以上操作便可实现仿淘宝颜色尺码选择功能
