从register.php向数据库中添加数据时遇到问题

having problems to adding data into DB from register.php

本文关键字：数据 遇到 问题 添加 register php 数据库 | 更新日期: 2024-01-16

我是PHP的新手，我正在做一些功课，并面临一些问题。我无法将register.php中的数据添加到xampp中托管的数据库中。有趣的是register.php不断刷新。请帮忙。不确定哪里有错误。我也检查了php.ini文件，并打开了错误error_reporting=E_ALL。

这是我的代码：

Register.php：

<?php
include("config.php");
$title=$_REQUEST['sel1'];
$fname=$_REQUEST['t1'];
$lname=$_REQUEST['t2'];
$gen=$_REQUEST['r1'];
$id=$_REQUEST['t3'];
$pass=$_REQUEST['p1'];
$phone=$_REQUEST['t5'];
$add=$_REQUEST['t6'];
$city=$_REQUEST['t7'];
$coun=$_REQUEST['t8'];
$dob=$_REQUEST['t9'];
if($_REQUEST['sub'])
{
$sel=mysqli_query("select id from register where id='$id' ");
$arr=mysqli_fetch_array($sel);

}
if($arr['id']!=$id)
  {
   if($_POST['sub'])
   mysqli_query("insert into register ('$title','$fname','$lname','$gen','$id','$pass','$phone','$add','$city','$coun','$dob')")
       {
         echo "<script>location.href='index.php?con=13 & wel=$id'</script>";
       }
     }
else
{
echo "user already exists";
}
}
?>

Config.php

<?php
mysqli_connect("localhost","root","");
mysqli_select_db("shop");
?>

更正插入查询

mysqli_query("insert into register 
(field_name1,field_name2,field_name3,field_name4,field_name5,field_name6,field_name7,field_name8,field_name9,field_name10,field_name11) 
values
('$title','$fname','$lname','$gen','$id','$pass','$phone','$add','$city','$coun','$dob')");

用寄存器表的列替换field_name
