Php 表单：从表单到mysql数据库表的数据提交

单击Submit按钮打开一个空白action.php，表中既没有任何错误消息，也没有数据插入

请求是否有人可以共享action.php的干净代码，或者指导我使用相同的代码。我在connection.php中有数据库登录凭据

我的表格有以下代码：

<form class="form-horizontal" action="action.php" method="Post">
    <div class="form-group">
        <label class="control-label col-sm-2" for="vlocation">Location:</label>

            $reg=$thisitem['location'];
            $sql= "select  id, location from location";          
            $res= mysql_query($sql);    
            $sql1= "select  * from location where id='$reg'";            
            $res1= mysql_query($sql1);
            $thiscat =mysql_fetch_array($res1);          
            ?>

请分享您的操作。phpWhy您使用的是长期不推荐的
mysql\uu
代码库？它在许多年前就已经停止使用，并在PHP7中被完全删除。不应使用此库编写新代码。它使您容易受到SQL注入攻击（由于缺少参数化查询支持）和其他潜在的未修补漏洞的攻击。尽快切换到使用
mysqli
或
PDO
，然后学习如何编写参数化查询以保护数据免受恶意输入。有关风险的简单解释和安全编写查询的一些PHP示例代码，请参阅。无论如何，正如前面提到的，如果问题是表单发布到action.PHP时发生了什么，那么我们当然需要查看该脚本的代码。我们无法修复我们看不见的东西。如果您得到一个空白页面，则表明脚本以某种方式崩溃，但您没有打开PHP错误报告。你可以用谷歌搜索方法来实现这一点。还要检查PHP错误是否被记录到磁盘上，然后您就可以访问磁盘了。一旦您得到准确的错误信息，诊断问题就会容易得多。这是调试错误时需要采取的第一个基本步骤。它显示以下消息（已成功连接）已成功创建新场馆记录。正在创建记录，但由于表单值在提交过程中丢失，因此为空。
