购物车勾选结算功能

开发使用的是ectouch企业版，带有购物车功能。
当前功能：在商品详情页面，点击添加购物车后，会进入购物车中。在购物车页面，点击‘立即购买’会将购物车中的全部商品都结算生成订单。
项目需求：添加购物中的商品前面带有‘勾选框’，点击已经勾选的商品才结算，其他的继续待在购物车中。

代码分析

查看ectouch代码，分析：

1. 商品如何进入购物车表
2. 购物车数量修改
3. 订单生成

商品进入购物车

前端页面点击改变商品数量，ajax方式发送商品id，数量到后台控制器
后台根据接收到的json数据添加向购物车中添加商品

购物车数量修改

每次点击‘+-’都会给后台发送一次ajax请求，实时更新数据表中的商品数量

订单生成

查看代码发现，在结算生成订单的时候，是依据当前用户Id，去查询购物车表中的商品，然后查询商品价格信息，全部进行结算的。

改造思路

分析后决定添加一个表，叫做‘虚拟车’，原购物车叫做‘结算车’，专门放购物车商品信息，不参与结算。勾选的商品再添加入购物车表，结算的时候会根据购物车中的商品结算。

具体步骤：

1. 新建‘虚拟车’表
2. 商品详情页面的‘加入购物车’按钮，改成添加到虚拟车
3. 购物车商品列表，显示虚拟车的数据
4. 购物车增加勾选框，商品数据修改都是修改虚拟车
5. 点击‘立即购买’，前端根据已勾选的商品数据发送ajax请求，添加到结算车
6. 订单确认页面是根据结算车中的商品数据生成的，提交订单后需删除虚拟车中对应的商品
7. 提交订单，会直接访问done()，在订单生成后，会有个清空购物车的操作，在这个操作之前，添加一个清空虚拟车的操作。

具体代码示例

这里贴出从进入购物车到结算的整个代码的大概流程

商品详情页添加购物车

商品详情页，点击加入购物车会有弹出框，选择数量，点击‘确定’添加到购物车
确定按钮的代码：

<a type="button" class="btn btn-block btn-primary text-center" style="background: #20A3DD;" href="javascript:addToCartNew_quick({$goods.goods_id}, 0, 0, '{$rfansid}')">确定</a>

这里调用了addToCartNew_quick，在common.js文件中，代码中注释的为修改为虚拟车之前的代码
代码如下：

function addToCartNew_quick(goodsId, parentId, sid, rfansid) {var goods = new Object();var spec_arr = new Array();var fittings_arr = new Array();var number = 1;var formBuy = document.forms['ECS_FORMBUY'];var quick = 0;// 检查是否有商品规格if (formBuy) {str = getSelectedAttributes(formBuy);spec_arr = str.split(',');if (formBuy.elements['number']) {number = formBuy.elements['number'].value;}quick = 1;}goods.quick = quick;goods.spec = spec_arr;goods.goods_id = goodsId;goods.number = number;goods.parent = (typeof (parentId) == "undefined") ? 0 : parseInt(parentId);goods.sceneid = sid;goods.rfansid = rfansid;$.post('index.php?m=default&c=flow&a=add_virtual_cart', {goods: $.toJSON(goods)}, function(data) {addToCartResponse_quick(data);}, 'json');//Ajax.call('index.php?m=default&c=flow&a=add_to_cart', 'goods=' + goods.toJSONString(), addToCartResponse_quick, 'POST', 'JSON');
}

后台的add_virtual_cart方法是新添加的，内部逻辑是仿照原有的add_to_cart，包括数据表的结构，也是参照原有的购物车表
代码如下：

public function add_virtual_cart(){//对goods处理$_POST ['goods'] = strip_tags(urldecode($_POST ['goods']));$_POST ['goods'] = json_str_iconv($_POST ['goods']);if (!empty($_REQUEST ['goods_id']) && empty($_POST ['goods'])) {if (!is_numeric($_REQUEST ['goods_id']) || intval($_REQUEST ['goods_id']) <= 0) {ecs_header("Location:./\n");}$goods_id = intval($_REQUEST ['goods_id']);exit();}// 初始化返回数组$result = array('error' => 0,'message' => '','content' => '','goods_id' => '','product_spec' => '');if (empty($_POST ['goods'])) {      //没有goods参数$result ['error'] = 1;die(json_encode($result));}$json = new EcsJson;$goods = $json->decode($_POST ['goods']);   //解析商品json数据$result['goods_id'] = $goods->goods_id;$result['product_spec'] = $goods->spec;// 查询：系统启用了库存，检查输入的商品数量是否有效// 查询$arrGoods = $this->model->table('goods')->field('goods_name,goods_number,extension_code')->where('goods_id =' . $goods->goods_id)->find();$goodsnmber = model('Users')->get_goods_number($goods->goods_id);$goodsnmber+=$goods->number;if (intval(C('use_storage')) > 0 && $arrGoods ['extension_code'] != 'package_buy') {if ($arrGoods ['goods_number'] < $goodsnmber) {$result['error'] = 1;$result['message'] = sprintf(L('stock_insufficiency'), $arrGoods ['goods_name'], $arrGoods ['goods_number'], $arrGoods ['goods_number']);if (C('use_how_oos') == 1){$result['message'] =L('oos_tips');}die(json_encode($result));}}// 检查：商品数量是否合法if (!is_numeric($goods->number) || intval($goods->number) <= 0) {$result ['error'] = 1;$result ['message'] = L('invalid_number');} else {// 更新：添加商品到到 虚拟车if (model('Order')->addto_virtual_cart($goods->goods_id, $goods->number, $goods->spec, $goods->parent, $goods->sceneid, $goods->rfansid)) {     // TODO 在前端发送的json数据中添加$goods->rfansidif (C('cart_confirm') > 2) {$result ['message'] = '';} else {$result ['message'] = C('cart_confirm') == 1 ? L('addto_cart_success_1') : L('addto_cart_success_2');}$result ['content'] = insert_cart_info();       // 此处是当前已勾选商品的信息$result ['one_step_buy'] = C('one_step_buy');} else {$result ['message'] = ECTouch::err()->last_message();$result ['error'] = ECTouch::err()->error_no;$result ['goods_id'] = stripslashes($goods->goods_id);if (is_array($goods->spec)) {$result ['product_spec'] = implode(',', $goods->spec);} else {$result ['product_spec'] = $goods->spec;}}}$cart_confirm = C('cart_confirm');$result ['confirm_type'] = !empty($cart_confirm) ? C('cart_confirm') : 2;// 返回购物车商品总数量$result ['cart_number'] = insert_cart_info_number();        // 此处是当前已勾选商品的信息die(json_encode($result));}

后台返回的是一个json数据，addToCartNew_quick中发送ajax后，调用addToCartResponse_quick来处理返回值
代码如下：

/* ** 处理添加商品到购物车的反馈信息*/
function addToCartResponse_quick(result) {if (result.error > 0) {// 如果需要缺货登记，跳转if (result.error == 1) {if(use_how_oos == 1){if (confirm(result.message)) {location.href = 'index.php?m=default&c=user&a=add_booking&id='+ result.goods_id + '&spec=' + result.product_spec;}}else{alert(result.message);}}// 没选规格，弹出属性选择框else if (result.error == 6) {openSpeDiv(result.message, result.goods_id, result.parent);} else {alert(result.message);}} else {var cartInfo = document.getElementById('ECS_CARTINFO');var cart_url = 'index.php?m=default&c=flow&a=cart';if (cartInfo) {cartInfo.innerHTML = result.content;}$('#model_sure').fadeIn(100);$('.to_cart').on('click',function () {$('#model_sure').fadeOut(100);location.href = cart_url;})// var returnVal = window.confirm("商品已成功加入购物车\n是否去购物车查看？", "标题");// if (returnVal) {//     location.href = cart_url;// }}

如果没有报错，会直接跳转到‘index.php?m=default&c=flow&a=cart’，也就是购物车页面

    /*** 购物车列表*/public function index() {$_SESSION['flow_type'] = CART_GENERAL_GOODS;/* 如果是一步购物，跳到结算中心 */if (C('one_step_buy') == '1') {ecs_header("Location: " . url('flow/checkout') . "\n");}// 取得商品列表，计算合计

购物车页面添加勾选框

<ul class="goods_list_box"><!-- {foreach from=$goods_list item=goods key=k} --><li style="position: relative;" class="active"><input type="hidden" name="sceneid" value="{$goods.sceneid}" class="goods_sceneid"/><input type="hidden" name="refer_fansid" value="{$goods.refer_fansid}" class="refer_fansid"/><div class="ect-clear-over"><i class="click pull-left"></i>     <!-- 这里添加勾选框 --><a href="{:url('goods/index',array('id'=>$this->_var['goods']['goods_id']))}"><img class="img-responsive" src="{$goods.goods_thumb}" title="{$goods.goods_name|escape:html}"></a><dl><dt><h4 class="title" style="font-size: 1em;"><a href="{:url('goods/index',array('id'=>$this->_var['goods']['goods_id']))}" style="width: 100%;">{$goods.goods_name}</a></h4></dt><!-- {if $goods.parent_id gt 0} 配件 --><span style="color:#ffae00">{$lang.accessories}</span><!-- {/if} --><!-- {if $goods.is_gift gt 0} 赠品 --><span style="color:#ffae00">{$lang.largess}</span><!-- {/if} --><dd class="ect-color999"><!-- {if $show_goods_attribute eq 1} 显示商品属性 --><p>{$goods.goods_attr|nl2br}</p><!-- {/if} --><div class="pull-right flow-del text-center" style="position: absolute; bottom: 0.6em; right: 0px;"><a class="" href="javascript:if (confirm('{$lang.drop_goods_confirm}')) location.href='{:url('flow/drop_virtual_cart_goods',array('id'=>$this->_var['goods']['rec_id']))}';" ><img class="delete" src="__TPL__/images/delete.png" alt=""></a></div><div class="ect-margin-tb ect-margin-bottom0 ect-clear-over flow-num-del" style="position: absolute; bottom: 0.6em; "><p><strong class="ect-colory">{$goods.goods_price}</strong></p><!-- {if $goods.goods_id gt 0 && $goods.is_gift eq 0 && $goods.parent_id eq 0} 普通商品可修改数量 --><div class="input-group pull-left wrap"> <span class="input-group-addon" onClick="change_goods_number('1',{$goods.rec_id})" >-</span><input type="hidden" id="back_number{$goods.rec_id}" value="{$goods.goods_number}" /><input type="text" class="form-num form-contro"  name="{$goods.rec_id}" id="goods_number{$goods.rec_id}" autocomplete="off" value="{$goods.goods_number}" onFocus="back_goods_number({$goods.rec_id})"  onblur="change_goods_number('2',{$goods.rec_id})" /><span class="input-group-addon" onClick="change_goods_number('3',{$goods.rec_id})">+</span> </div><!-- {else} -->数量{$goods.goods_number}<!-- {/if} --></div></dd></dl></div></li><!-- {/foreach} -->

点击切换图标的效果，是在上绑定了点击事件

    //选中/不选中商品function onchoice() {$('.click').on('click',function () {var a=$(this).parent().parent();if(a.hasClass('active')){a.removeClass('active');}else {a.addClass('active');}offSure();})}onchoice();

对商品数量的修改也更改了，点击‘+-’会调用change_goods_number

//实时更新数据function change_goods_number(type, id) {var goods_number =document.getElementById('goods_number' + id).value;
//        console.log(goods_number);if (type != 2) {back_goods_number(id)}if (type == 1) {goods_number--;}if (type == 3) {goods_number++;}if (goods_number <= 0) {goods_number = 1;}//防止输入非法数量----测试结结果是否为数字if (!/^[0-9]*$/.test(goods_number)) {goods_number = document.getElementById('goods_number' + id).value;}if (goods_number===undefined){//发请求修改数据库的商品数量document.getElementById('goods_number' + id).value = 0;$.post('{:url("flow/ajax_update_virtual_cart")}', {rec_id: id, goods_number: 0}, function (data) {change_goods_number_response(data, id);}, 'json');}else {//var goods_number = document.getElementById('goods_number' + id).value;document.getElementById('goods_number' + id).value = goods_number;$.post('{:url("flow/ajax_update_virtual_cart")}', {rec_id: id, goods_number: goods_number}, function (data) {change_goods_number_response(data, id);}, 'json');}}

在这里面，还有调用了一个函数，获取当前的商品数量

    //获取需要提交的信息function back_goods_number(id) {var goods_number = document.getElementById('goods_number' + id).value;
//        console.log(goods_number);if(goods_number!==undefined){document.getElementById('back_number' + id).value = goods_number;}else {document.getElementById('back_number' + id).value = 1;}}

更改购物车数据，访问的是后台接口{:url("flow/ajax_update_virtual_cart")}

根据返回信息，修改页面上的商品数量

// 处理返回信息并显示

}

点击‘立即购买’按钮，触发事件

到此，订单生成，该修改完成了。

关键点有两个：

1. 新建虚拟车表，记录购物车中的数据，结算车始终保持空的
2. 根据勾选的虚拟车商品插入结算车前，清空结算车；订单生成后，根据结算车清空虚拟车

应该有比这个更简单的方案。
例如直接用购物车勾选的内容来生成订单，不走之前生成订单的逻辑。
本人对ectouch的修改把握不大，就用了比较繁琐保守的修改方法。
