Php 贝宝-如何检索已发布的数据

所以，我正在做一个网站销售会员计划。用户点击计划，系统将显示一张登记表。在表单中，我需要获得用户的IC卡号码（这是我工作所在国家的合法身份证号码）和用户创建的密码。然后，用户单击“订阅”按钮。用户将被引导到paypal处理页面

form method='post' action="https://www.sandbox.paypal.com/cgi-bin/webscr" method="post">
        <input type="hidden" name="cmd" value="_ext-enter">
        <input type="hidden" name="redirect_cmd" value="_xclick-subscriptions">
        <input type="hidden" name="item_number" value="<?php echo $plan[0]['id'];?>">
        <input type="hidden" name="no_note" value="1">
        <input type="hidden" name="item_name" value="<?php echo $plan[0]['plan_name'];?>">  
        <input type="hidden" name="currency_code" value="USD">
        <input type="hidden" name="a3" value="<?php echo $plan[0]['plan_price'];?>">  

        <input type="hidden" name="p3" value="1">  

        <input type="hidden" name="t3" value="D">   
        <input type="hidden" name="src" value="1">
        <input type="hidden" name="sra" value="1">

        <input type="hidden" name="business" value="seller@test.com">

        <input type="hidden" name="return" value="<?php echo base_url(); ?>">
        <input type="hidden" name="notify_url" value="<?php echo base_url(); ?>payment/subscribe" />
         <input type="hidden" name="rm" value="2">
       <label for='icno'>IC No</label><input type='text' name='icno'/>
       <label for='password'>Password</label><input type='password' name='password'/>
       <input type='image' src="<?php echo base_url(); ?>assets/images/sign_up_btn.png" alt="" border="0" />
 </form>

因此，采购过程进展顺利。问题是，如果用户单击返回按钮返回我们的站点，它将不会更新DB（插入测试（名称）值（“$icno”）。我做错了什么

顺便说一句，用户返回主站点后，会创建一个.txt文件，但只存储此信息

如果你问我为什么不尝试IPN；我刚开始学习如何整合paypal，因此我最好学习如何两者兼而有之

我试图改变：

if (strcmp ($res, "VERIFIED") == 0) {

        $s = "insert into test(name) values('$icno')";
            $result = mysql_query($s);
    }

到

它仍然不会更新数据库

您知道$icno中存储了什么值吗？在获取数据方面，您还可以使用Codeigniter的输入类。
