修改如下

在

/js/common.js

function  addToCar(){

//找到

        goods.quick    = quick;

    goods.spec     = spec_arr;

    goods.goods_id = goodsId;

    goods.number   = number;

在其下面增加一行

  goods.liji=1;//立即购买

}

修改flow.php

找到

$_REQUEST['step'] == 'add_to_cart'

在其逻辑里修改

将

    

  if ($_CFG['one_step_buy']) {   

        clear_cart();

     }

修改为

    $go_id=$goods->liji;

  if ($_CFG['one_step_buy'] == '1' || $go_id==1) {   

        clear_cart1($goods->goods_id);

     }

找到

if (addto_cart($goods->goods_id, $goods->number, $goods->spec, $goods->parent, $warehouse_id, $area_id, $goods->stages_qishu, $goods->store_id,

$goods->end_time, $goods->store_mobile))

修改为

if (addto_cart($goods->goods_id, $goods->number, $goods->spec, $goods->parent, $warehouse_id, $area_id, $goods->stages_qishu, $goods->store_id,

$goods->end_time, $goods->store_mobile,$goods->liji))   //即增加一个参数

在/includes/lib_order.php

找到

function clear_cart($type = CART_GENERAL_GOODS, $cart_value = '')

{

}

在其函数下增加一个新函数

function clear_cart1($goods_id)

{

    

    if (!empty($_SESSION['user_id'])) {

        $sess_id = ' user_id = \'' . $_SESSION['user_id'] . '\' ';

    }

    else {

        $sess_id = ' session_id = \'' . real_cart_mac_ip() . '\' ';

    }

    $goodsIn = '';

    if (!empty($cart_value)) {

        $goodsIn = ' and rec_id in(' . $cart_value . ')';

    }

    $sql = 'DELETE FROM ' . $GLOBALS['ecs']->table('cart') . ' WHERE goods_id='.$goods_id.' and ' . $sess_id . (' AND rec_type = \'' . $type .

'\'') . $goodsIn;

    $GLOBALS['db']->query($sql);

    if (!empty($_SESSION['user_id'])) {

        $sess_id = ' user_id = \'' . $_SESSION['user_id'] . '\' ';

    }

    else {

        $sess_id = ' user_id = \'' . real_cart_mac_ip() . '\' ';

    }

}
