<?php
session_start();
include_once("DB.class.php"); 

    //接受并解析前端传过来的json,转换成数组。
    $goods_list =$_POST['order'];
    $goods_list= json_decode($goods_list, true);
        
        //1.获取session信息
        $arr = $_SESSION['gwc'];
        //获得订单数组
        $item_list = $goods_list['order'];

        //一维实现,每次先清空订单。
        $order = '';
        
        //把商品信息存到订单,并且把他们从购物车中删除
        foreach($item_list as $k=> $item){
            
                //把商品信息存到订单
                $order[$k] = $arr[$k];

                //把商品信息从购物车中删除
                unset($arr[$k]);

                
        }

        //更新购车的商品信息
        if(!empty($arr)){
            $_SESSION['gwc'] = $arr;
        }else{
            $_SESSION['gwc'] = '';
        }
        
            //最后将订单信息存到session
            $_SESSION['order'] = $order;
        
        
        // var_dump($_SESSION);
        // die();    
        echo "OK";
        exit;

?>

业务逻辑

  • 从购物车中点击结算,即是把商品信息从购物车中转移到订单中。
  • 技术点:接受的方式是json。要先在前台以json的形式传过来,这里再把它解析为数组,再运用。

购物车页面的结算按钮注册点击事件(需要引入jquery文件)

$('#jiesuan').click( function(){
        //间接设置订单金额
        var j = $('.total_text').text();
        // 去除¥符号
        var order_toal = j.substring(1);
        //将标签的值赋给input传过去
        $("#order_total").val(order_toal);
        //用插件将表单生成json,在ajax发送过去后台
            var serializeObj=$('#form1').serializeJSON();
var serializeStr=JSON.stringify(serializeObj);
console.log(serializeStr);
$.ajax({
      cache: false,
      type: "POST",
      url : "add_to_order.php",
      traditional:true,  
      data: {order : serializeStr}, //注意这里的写法,键为order
      success: function(msg){
        if(msg=="OK"){
        
            alert("下单成功");
           // location.reload();
           //window.location.href='order.php';
        }else{
            alert(msg);
            alert("下单失败");
        }
      }
    });

 这是表单中的一部分,展示如何把选中的商品传过去。关键在于checbox键值设置:在foreache循环中,所以键值得有变量混合进去。(仅展示代码,复制有样式问题)

 注意事项

可以给商品的checkbox类型添加name属性是因为他有selected属性,而其他像hidden类型的不能给它name属性,否则也会提交到后台。要保持提交过去的数据不能有冗余,需要遍历。

而且添加到订单也只需商品id就行,订单的商品数量可以在根据key在gwc中获得。具体看add_to_order.php.
