首先编写html页面:

    <meta charset="UTF-8">    <title>订单页面</title><h2>Jason的购物清单</h2>
Copy after login


再用PHP编写服务器端脚本文件processorder.php

<?php $cloths=$_POST['cloths'];    $shoes=$_POST['shoes'];    $glasses=$_POST['glasses'];    $address=$_POST['address'];    $DOCUMENT_ROOT=$_SERVER['DOCUMENT_ROOT'];    //设置时区    date_default_timezone_set('Asia/Shanghai');    //按指定格式输出日期    $date=date('Y-m-d H:i');?>    <meta charset="UTF-8">    <title>订单结果</title><h2>Jason的购物车</h2><h3>订单结果</h3><?php echo '<p>订单提交中时间:'.$date.'';    echo '<p>您的具体购物清单是:</p>';    //获取商品总数量    $total_qty=0;    $total_qty=$cloths+$shoes+$glasses;    echo '商品总数量:'.$total_qty.'<br>';    if($total_qty==0){        echo '您没有购买任何商品!';    }else{        if($cloths>0){            echo $cloths.'件男装<br>';        }        if($shoes>0){            echo $shoes.'双鞋子<br>';        }        if($glasses>0){            echo $glasses.'副眼镜<br>';        }    }    //获取商品总价    $total_amount=0.00;    const CLOTHS_PRICE=100;    const SHOES_PRICE=300;    const GLASSES_PRICE=28;    $total_amount=$cloths*CLOTHS_PRICE+$shoes*SHOES_PRICE+$glasses*GLASSES_PRICE;    $total_amount=number_format($total_amount,2,'.',' ');    echo '<p>商品总价:¥'.$total_amount.'</p>';    echo '<p>收货地址:'.$address.'</p>';    //设置文件输出内容和格式    $out_put_string=$date."\t".$cloths."件男装\t".$shoes."双鞋子\t".$glasses."副眼镜\t\总价:¥".$total_amount." 收货地址:\t".$address."\n";    //打开文件,(追加模式+二进制模式)    @$fp=fopen("$DOCUMENT_ROOT/L02/files/orders.text",'ab');    flock($fp,LOCK_EX);    if(!$fp){        echo "<p><strong>您的订单没有提交完成,请再试一次。</strong></p>";        exit;    }    //将数据写入到文件    fwrite($fp,$out_put_string,strlen($out_put_string));    flock($fp,LOCK_UN);    //关闭文件流    fclose($fp);    echo "<p>数据保存完成</p>";?>
