3. As for the jquery file, it is compatible with versions 1.3 and 1.4 and can be downloaded by yourself. The source code of the file addBuyCar.js is as follows:

The code is as follows:

function AddProduct(classid,id) {
$.ajax({
type: "post",
url: newsurl+"e/template/ShopSys/addBuyCar.php",
data:"classid="+classid+"&id="+id,
dataType: "json",
success: function (json) {
alert(json.msg);
}
})
}

Copy after login

Fourth, add the handler e/template/ShopSys/addBuyCar.php, its source code is as follows:

The code is as follows:

<?php
require("../../class/connect.php");
require("../../class/db_sql.php");
require("../../data/dbcache/class.php");
require("../../class/ShopSysFun.php");
$link=db_connect();
$empire=new mysqlquery();</p> <p>//$_POST
$classid=(int)$_POST[&#39;classid&#39;];
$id=(int)$_POST[&#39;id&#39;];</p> <p>//add function
function json_AddBuycar($classid,$id){
global $class_r,$empire,$dbtbpre,$public_r;
$classid=(int)$classid;
$id=(int)$id;
if(empty($classid)||empty($id)||empty($class_r[$classid][tbname]))
{
return json_encode(array(&#39;msgid&#39;=>1,&#39;msg&#39;=>&#39;此商品不存在&#39;));
}
//验证产品是否存在
$num=$empire->gettotal("select count(*) as total from {$dbtbpre}ecms_".$class_r[$classid][tbname]." where 
classid=&#39;$classid&#39; and id=&#39;$id&#39; limit 1");
if(!$num)
{
return json_encode(array(&#39;msgid&#39;=>1,&#39;msg&#39;=>&#39;此商品不存在&#39;));
}
$record="!";
$field="|";
$productid=$classid.",".$id;
$buycar=getcvar(&#39;mybuycar&#39;);
//重复
if(strstr($buycar,"|".$productid."|"))
{
$pr=explode("|".$productid."|",$buycar);
$pr1=explode("!",$pr[1]);
$oldbuycar="|".$productid."|".$pr1[0]."!";
//数量
$pr1[0]=ReturnBuycarProductNum($pr1[0]);
if(empty($pr1[0]))
{
$pr1[0]=1;
}
$newnum=$pr1[0]+1;
$newbuycar="|".$productid."|".$newnum."!";
$buycar=str_replace($oldbuycar,$newbuycar,$buycar);
}
else
{
//只存放一个
if($public_r[&#39;buycarnum&#39;]==1)
{
$buycar=&#39;&#39;;
}
$buycar.="|".$productid."|1!";
}
$re=SetBuycar($buycar);
if($re)
{
return json_encode(array(&#39;msgid&#39;=>2,&#39;msg&#39;=>&#39;商品加入购物车成功&#39;));
}
}
echo json_AddBuycar($classid,$id);
db_close();
$empire=null;
?>
