我为我的网站创建了一个登录页面。与数据库的连接很好，我正在登录表单中键入数据库中的正确值。我在数据库和代码中都有密码md5。然而，当我检查是否有任何行回来时，没有。我想再看一眼可能是一个愚蠢的错误。
<?php
$email = $_POST['email'];
$password = $_POST['password'];
$password = md5($password);
$query = "SELECT * FROM users WHERE password = '$password' AND email='$email' AND activated='1'";
$queryrun = mysql_query($query);
while($row = mysql_fetch_assoc($queryrun)) {
$fname = $row['firstname'];
echo $fname;
}
$logincheck = mysql_num_rows($queryrun);
if ($logincheck > 0) {
echo 'good, you are in our database';
} else {
echo 'sorry, you are not in our database';
}
?>
