用户''@ localhost'拒绝访问数据库'finalproject'

Question

可能重复:
PHP - MySQL访问被拒绝错误 - 在其他程序中工作

我正在尝试建立一个登录过程,在我的phpmyadmin中连接我的AdminLogin2.php和admin2表,但它表示拒绝访问.我不知道该怎么做才能解决它.希望有人可以帮助我.在这里我的代码,谢谢.

`<?php

$host="localhost";
$username="root";
$password="";
$database="finalproject";
$table="admin2";

$AdminID=$_POST['Field1'];
$Password=$_POST['Field3'];

mysql_connect("$host","$password") or die (mysql_error());
#echo"connected";
mysql_select_db("$database") or die (mysql_error());
#echo"database found";

// To protect MySQL injection (more detail about MySQL injection)
$AdminID = stripslashes($AdminID);
$Password = stripslashes($Password);
$AdminID = mysql_real_escape_string($AdminID);
$Password = mysql_real_escape_string($Password);
$sql="SELECT * FROM $admin2 WHERE username='$AdminID' and password='$Password'";
$result=mysql_query($sql);

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);

// If result matched $myusername and $mypassword, table row must be 1 row
if($count==1){

// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("myusername");
session_register("mypassword"); 
header("location:AdminForm.php");
}
else {
echo "Wrong Username or Password";
}
?>

Answer 1

mysql_connect("$host","$password")

应该是这样的

mysql_connect("$host","$username","$password")

这就是为什么你从数据库中获取空用户名的错误
