我是php.my的新用户，输入表单没有将任何内容保存在我的PHPMYADMIN数据库中，但是每次我按我的REGISTER按钮时，它都会显示“ register = success”即使它没有插入到我的数据库中，也没有在任何行中显示任何错误。___________________________________________________________________________

this is inside my register.php
<?php
include_once 'includes/conn.php';
$fname=$_POST['fName'];
$lName=$_POST['lName'];
$plateNo=$_POST['plateNo'];
$vBrand=$_POST['vBrand'];
$color=$_POST['color'];
$sql = "INSERT INTO register(name,lastname,Plateno,vehiclebrand,color)
VALUES($fname,$lName,$plateNo,$vBrand,$color);";
mysqli_query($conn,$sql);
header("Location: ../index.php?register=success");
?>

这是在我的conn.php中
<?php
$dbSname='localhost';
$dbUname ='root';
$pwd='';
$dbName = 'capstone';
$conn = mysqli_connect($dbSname,$dbUname,$pwd,$dbName);
我期望我的输入将数据保存到我的phpmyadmin数据库中
首先，您需要知道在运行查询时是否发生错误。因此，我的建议是更改您的。php
脚本以处理异常，如下所示：
