WBOYOriginal: 2016-07-30 13:31:341614browse

First write the html page:

<!DOCTYPE html>
<html>
<head lang="zh_CN">
    <meta charset="UTF-8">
    <title>订单页面</title>
</head>
<body>
<h2>Jason的购物清单</h2>
<form method="post" action="processorder.php">
    <label>男装:</label><input type="text" name="cloths"/>
    <label>鞋子:</label><input type="text" name="shoes"/>
    <label>眼镜:</label><input type="text" name="glasses"/>
    <label>收货地址：</label><input type="text" name="address"/>
    <input type="submit" value="提交" id="btn1">
</form>
</body>
</html>

Then use PHP to write the server-side script fileprocessorder.php

<?php
    $cloths=$_POST[&#39;cloths&#39;];
    $shoes=$_POST[&#39;shoes&#39;];
    $glasses=$_POST[&#39;glasses&#39;];
    $address=$_POST[&#39;address&#39;];
    $DOCUMENT_ROOT=$_SERVER[&#39;DOCUMENT_ROOT&#39;];
    //设置时区
    date_default_timezone_set(&#39;Asia/Shanghai&#39;);
    //按指定格式输出日期
    $date=date(&#39;Y-m-d H:i&#39;);

?>
<!DOCTYPE html>
<html>
<head lang="zh_CN">
    <meta charset="UTF-8">
    <title>订单结果</title>
</head>
<body>
<h2>Jason的购物车</h2>
<h3>订单结果</h3>
<?php

    echo &#39;<p>订单提交中时间：'.$date.'</p>';
    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></body></html>";
        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>";

?>
</body>
</html>
