我似乎无法弄清楚我做错了什么。所以当我提交我的表单时，我收到警告错误和
Notice: Undefined variable: dbusername in /Library/WebServer/Documents/ArturoLuna_Final/loginCheck.php on line 30
$username = $_POST['username'];
$password = $_POST['password'];
if($username&&$password)
{
require 'conn.php';
$query = "SELECT * FROM users WHERE username='$username'";
$result = $mysql->query($query) or die(mysqli_error($mysql));
$numrows = $result->num_rows;
if ($numrows!=0)
{
while($row = mysql_fetch_assoc($result))
{
$dbusername = $row['username'];
$dbpassword = $row['password'];
}
//check to see if they match!
if($username==$dbusername&&$password==$dbpassword)
{
echo "youre In!";
}
else
echo "incorrect password!";
}
else
die("that user is dead");
//echo $numrows;
}
else
echo ("Please Enter Username")
我可能做错了什么？
