最近有一个需求,前端向后台提交json,后台解析并且将提交的值插入数据库中,
难点
1、php解析json(这个不算难点了,网上实例一抓一大把)
2、解析json后,php怎样拿到该拿的值
<?phprequire ('connect.php');/*本例用到的数据:post_array={"order_id":"0022015112305010013","buyer_id":"2","seller_id":"1","all_price":"100.00","json_list":[{"product_id":"3","product_number":"3"},{"product_id":"8","product_number":"2"},{"product_id":"10","product_number":"4"}]} */$post_array=$_POST['post_array'];//--解析Json,获取对应的变量值$obj=json_decode($post_array,TRUE);$order_id = $obj['order_id'];$buyer_id = $obj['buyer_id'];$seller_id = $obj['seller_id'];$all_price = $obj['all_price'];$i=0;//循环变量//--得到Json_list数组长度$num=count($obj["json_list"]);//--遍历数组,将对应信息添加入数据库for ($i;$i<$num;$i++){ $list_product_id[]=$obj["json_list"][$i]["product_id"]; $list_product_number[]=$obj["json_list"][$i]["product_number"]; $insert_order_product_sql="INSERT INTO tbl_order_product (order_id,product_id,product_number) VALUES (?,?,?)"; $result = $sqlconn -> prepare($insert_order_product_sql); $result -> bind_param("sss", $order_id,$list_product_id[$i],$list_product_number[$i]); $result->execute();}//--添加订单信息$insert_order_sql="INSERT INTO tbl_order (order_id,buyer_id,seller_id,all_price) VALUES (?,?,?,?)";$result=$sqlconn->prepare($insert_order_sql);$result->bind_param("ssss",$order_id,$buyer_id,$seller_id,$all_price);$result->execute();$result -> close();$sqlconn -> close();?>
