我是PDO PHP的新手(刚开始今天)。我试图写一个登录函数,但它返回false,即使我知道凭据是正确的。PDO脚本获取行数不工作?
我认为是尝试获取触发脚本的行数量,你能帮忙吗?
function check_login($email, $username, $password)
{
$host = 'localhost';
$port = 3306;
$database = 'example';
$username = 'root';
$password = '';
$dsn = "mysql:host=$host;port=$port;dbname=$database";
$db = new PDO($dsn, $username, $password);
$password = md5($password);
$statement = $db->prepare("SELECT * FROM users WHERE email = ? or username = ? and password = ?");
$statement->execute(array($email, $username, $password));
while ($result = $statement->fetchObject()) {
$sql = "SELECT count(*) FROM users WHERE email = ? or username = ? and password = ?";
$result1 = $db->prepare($sql);
$result1->execute(array($email, $username, $password));
$number_of_rows = $result1->fetchColumn();
if ($number_of_rows == 1)
{
$_SESSION['login'] = true;
$_SESSION['uid'] = $result->uid;
return TRUE;
}
else
{
return FALSE;
}
}
}
