你们如何使用mysql将用户输入从文本框（html / php）插入数据库（phpmyadmin）
我不断收到错误“无法插入”的提示，我的代码中缺少某些内容。
我确实在网上搜索了如何修复它，但没有任何效果。我认为我的代码中缺少某些内容，我无法指出。
下面的所有文件都在1个名为index.php的php文件中
<!DOCTYPE html>
<?php
$dbhost = 'localhost';
$dbuser = 'root';
$dbpass = '';
$db = 'dad_trading';
$dbconn = mysql_connect($dbhost, $dbuser, $dbpass);
mysql_select_db($db);
if (isset($_POST['submit']))
{
$Lastname = $_POST['LastName'];
$firstname = $_POST['FirstName'];
$Middlename = $_POST['MiddleName'];
$address = $_POST['Address'];
$city = $_POST['City'];
$zipcode = $_POST['ZipCode'];
$email = $_POST['email'];
$number = $_POST['number'];
$query = ("INSERT INTO customer ([LName], [FName], [MName], [Street], [City], [ZipCode], [Email], [ContactNo]) VALUES ('$Lastname', '$firstname', '$Middlename', '$address', '$city','$zipcode', '$email', '$number')");
if(mysql_query($query))
{
echo "<script>alert('INSERTED SUCCESSFULLY');</script>";
}
else
{
echo "<script>alert('FAILED TO INSERT');</script>";
}
}
?>

尝试使用服务器变量添加表单操作
<form action="<?php echo $_SERVER['PHP_SELF'];?>" method="post">
