我正在使用单选按钮和下拉菜单制作一个简单的注册表单。
我的问题是我无法将表单数据插入到我的数据库中。我想我不是在捕捉表单数据，但我不确定。
因为当我提交表单时，我收到错误SORRY! ERROR while inserting record !，它告诉我它无法插入。我试图添加
ini_set('display_errors',1);
ini_set('display_startup_errors',1);
error_reporting(E_ALL);
所以我看到了我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。
网页代码：
<?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");

答案 0 :(得分：0)
您的问题是您没有正确编码HTML中的k代码。
每个<input>标记都需要<input>属性，因为它是此属性，而不是浏览器用来创建name=""对的id="" name=value 1}}或$_GET变量
所以修改你的代码并在所有输入标签中添加$_POST属性，如下所示： -
name=""等等，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<input type="text" name="first_name" class="form-control" id="inputFirstName" placeholder="first name">
与$ _POST ['last_name']相同。
大小写也应该匹配，因此name="last_name"和name='Employee NRC'不匹配且无法正常工作。也不要在$_POST['employee_nrc'];中添加空格，删除空格，或者在name='Employee NRC'这样的名称中使用下划线_。
