创建了数据库和表，但表单值没有进入数据库表表单字段值是绝对正确的，我通过echo 检查了它们
我的insert into sql命令中有错误吗。代码如下
<html>
<head>
<title></title>
</head>
<body>
<?php
$servername="localhost";
$username="root";
$password="";
$conn = new mysqli($servername, $username, $password);
if ($conn->connect_error)
{
die("Connection failed: " . $conn->connect_error);
}
$conn->query("CREATE DATABASE IF NOT EXISTS `B2B`");
$sql1="CREATE TABLE IF NOT EXISTS `B2B`.`company_details`(
`email` VARCHAR(30) NOT NULL,
`password` VARCHAR(20) NOT NULL,
`company_name` VARCHAR(70) NOT NULL,
`address` VARCHAR(150) NOT NULL,
`website` VARCHAR(70),
`phone` VARCHAR(20),
`mobile` VARCHAR(20) NOT NULL,
`fax` VARCHAR(20),
`contact_person` VARCHAR(30) NOT NULL,
`deals_in` VARCHAR(300),
`Introduction` VARCHAR(400),

if($conn->query($sql1))
{
echo 'table is created succssfully';
}
function test_data($data)
{
$data=trim($data);
$data=stripslashes($data);
$data=htmlspecialchars($data);
return $data;
}
$errors = array();
if ( $_SERVER["REQUEST_METHOD"] =="POST" )
{
$email=test_data($_POST["email"]);
$password=test_data($_POST["password"]);
$companyName=test_data($_POST["companyName"]);
$introduction=test_data($_POST["introduction"]);
$deals_in=test_data($_POST["deals_in"]);
$address=test_data($_POST["address"]);
$website=test_data($_POST["website"]);
$phone=test_data($_POST["phone"]);
$mobile=test_data($_POST["mobile"]);
$fax=test_data($_POST["fax"]);
$contact_person=test_data($_POST["contact_person"]);
$sql="INSERT INTO `company_details` (`company_name`, `address`, `email`, `mobile`, `contact_person`, `password`, `website`, `phone`, `fax`, `introduction`, `deals_in` ) VALUES ( '".$companyName."', '".$address."', '".$email."', '".$mobile."', '".$contact_person."', '".$password."', '".$website."', '".$phone."', '".$fax."', '".$introduction."', '".$deals_in."')";
$conn->select_db('B2B');
$conn->query($sql);
}
else
{
echo '<h2>Access is Denied</h2>';
}
$conn->close();

您将介绍列定义为
`Introduction` VARCHAR(400),
但试图在"介绍"中插入日期，即：未大写：
..., `introduction`, `deals_in` )....
因此，您需要更改创建表的脚本或查询。考虑到没有其他列是大写的，我建议使用"introduction"作为列名。
