PHP连接错误;不允许连接到MySQL服务器

问题描述

我正在尝试创建一个注册页面，将信息添加到SQL Table中。这是我的PHP代码来做到这一点...任何人都可以告诉我这是什么错误？

 <？php 
 $ con = mysqli_connect（正确的网站在这里，正确的用户名，正确的通行证，正确的数据库）; 
 if（mysqli_connect_errno（））
 {
 echo无法连接到MySQL：。 mysqli_connect_error（）; 
} 
 
 $ DBsql = mysql_query（SELECT username，email from Profiles）; 
 $ sql = mysql_fetch_array（$ DBsql）; 
 
 if（！（$ _ POST ['username'] == $ sql ['username']）&&（$ _POST ['email'] == $ sql ['email'] ））{
 if（$ _POST ['password'] == $ _POST ['password2']）{
 $ sql =插入配置文件（firstName，lastName，username，email，password，region ，组，已验证）
 VALUES 
（'$ _POST [firstname]'，'$ _ POST [lastname]'，'$ _ POST [用户名]'，'$ _ POST [email]'，'$ _ POST [密码]， '$ _ POST [区域]'， '部件'， '无'）; 
} else {
 echo'< script type =text / javascript>'
，'window.alert（密码不匹配）'
 ，'< / script>'; 
 $ b} else {
 echo'< script type =text / javascript>'
'，window.alert（该用户名或电子邮件已被使用。）'
，'< / script>'; 
} 
 
 mysqli_close（$ con）; 
？> 
  

这是错误提示：

<$ p $警告：mysqli_connect（）[function.mysqli-connect]：（HY000 / 1130）：主机'31.170.161.96'不允许连接到这个MySQL服务器的/ home / a5349216 / public_html /第二行的register.php

无法连接到MySQL：主机'ip'不允许连接到这个MySQL服务器

警告：mysql_query（）[function.mysql -query]：在第8行的/home/username/public_html/register.php中访问被用户'用户名'@'localhost'拒绝（使用密码：NO）

警告：mysql_query（）[function .mysql-query]：无法在第8行的/home/username/public_html/register.php中建立到服务器的链接

警告：mysql_fetch_array（）：提供的参数不是有效的MySQL结果资源位于第9行的/home/username/public_html/register.php上

警告：mysqli_close（）期望参数1为mysqli，布尔在/home/username/public_html/register.php中给出o第27行

感谢您的进一步支持。

I am trying to make a registration page where it adds the information to a SQL Table. Here is my PHP code to do this... Can anyone tell me what the error with this is?

<?php
$con=mysqli_connect("Correct Website is here","Correct Username","Correct Pass","Correct DB");
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

$DBsql = mysql_query("SELECT username, email from Profiles");
$sql = mysql_fetch_array($DBsql);

if(!($_POST['username'] == $sql['username']) && ($_POST['email'] == $sql['email'])) {
 if ($_POST['password'] == $_POST['password2']){
  $sql="INSERT INTO Profiles (firstName, lastName, username, email, password, region, group, verified)
  VALUES
  ('$_POST[firstname]','$_POST[lastname]','$_POST[username]','$_POST[email]','$_POST[password]','$_POST[region]','member','no')";
 }else{
     echo '<script type="text/javascript">'
   , 'window.alert("The passwords do not match.")'
   , '</script>';
 }
} else {
    echo '<script type="text/javascript">'
   , 'window.alert("That username or email is already in use.")'
   , '</script>';
}

 mysqli_close($con);
?>

It's giving these errors:

Warning: mysqli_connect() [function.mysqli-connect]: (HY000/1130): Host '31.170.161.96' is not allowed to connect to this MySQL server in /home/a5349216/public_html/register.php on line 2

Failed to connect to MySQL: Host 'ip' is not allowed to connect to this MySQL server

Warning: mysql_query() [function.mysql-query]: Access denied for user 'username'@'localhost' (using password: NO) in /home/username/public_html/register.php on line 8

Warning: mysql_query() [function.mysql-query]: A link to the server could not be established in /home/username/public_html/register.php on line 8

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/username/public_html/register.php on line 9

Warning: mysqli_close() expects parameter 1 to be mysqli, boolean given in /home/username/public_html/register.php on line 27

Thanks in advanced.

解决方案

If your mysql database is not on the same server(localhost) you need to give it access from a remote server for that mysql user/database for your server. See this article for some steps that might help you. It sounds like it might be remote.
