使用下拉菜单捕获数据，mysql中的单选按钮答案

【问题标题】：capturing data using dropdown menu,radio buttons in mysql使用下拉菜单捕获数据，mysql中的单选按钮
【发布时间】：2016-03-23 06:51:20
【问题描述】：

我正在制作一个带有单选按钮和下拉菜单的简单注册表。

我的问题是我无法将表单数据插入我的数据库。我想我没有捕获表单数据，但我不确定。因为当我提交表单时，我收到错误SORRY! ERROR while inserting record !，它告诉我插入失败。我尝试添加

ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);

这样我就可以看到页面上显示的实际错误，但我仍然无法弄清楚我做错了什么。

页面代码：

         <?php
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);


include_once 'dbconfig.php';
if(isset($_POST['btn-save']))
{
    $fname = $_POST['first_name'];
    $lname = $_POST['last_name'];
    $employee_nrc = $_POST['employee_nrc'];
    $Phone = $_POST['phone_no'];
    $Businesstype = $_POST['business_type'];
    $Businesssite = $_POST['business_site'];
    $Businessactivity = $_POST['business_activity'];
    if($crud->create($fname,$lname,$employee_nrc,$Phone,$Businesstype,$Businesssite,$Businessactivity))
    {
        header("Location: add-data.php?inserted");
    }
    else
    {
        header("Location: add-data.php?failure");

你能告诉我们具体的错误吗？
我得到的错误是我自己的错误，我把它放在代码中。 e 对不起！插入记录时出错！
@bli 您的 create 方法有 echo $e->getMessage(); 行 - 不要让您的代码重定向会删除消息。阅读消息。 SORRY ERROR 不是一个有意义的编程消息，我们无法调试它。

标签： php html mysql pdo

【解决方案1】：

您的问题是您没有正确编码 HTML 中的 <input> 标记。

每个<input> 标记都需要一个name="" 属性，因为它是该属性，而不是浏览器用来创建name=value 对的id=""，它们作为$_GET 或$_POST 变量发送

所以修改你的代码并为所有输入标签添加一个name="" 属性，如下所示：-

<input type="text" name="first_name" class="form-control" id="inputFirstName"  placeholder="first  name">

对所有输入字段以此类推，确保您为每个输入提供的名称与您在 PHP 代码中使用的名称相匹配。

还要确保name="last_name" 与$_POST['last_name'] 相同。

大小写也应该匹配，所以name='Employee NRC' 和$_POST['employee_nrc']; 不匹配并且不会工作。也不要在 name='Employee NRC' 中添加空格，要么删除空格，要么在名称中添加下划线 _，例如 name='employee_nrc'。

【讨论】：

我已经尝试过这样做，但我仍然无法插入数据，我已经编辑了我的问题，请检查我是否仍然缺少某些东西
在我的回答中查看更多信息。
完成但仍然得到相同的错误响应，我无法插入
您最好再次更新问题中的代码
$_POST['employee_nrc']; 不等于name="Employee_nrc" 大小写也必须相同。请检查其他不匹配情况
