[請益] 會員系統疑問
if (isset($_POST['username']) && isset($_POST['password']))
{
$_SESSION['username'] = $_POST['username'];
$username = $_POST['username'];
$password = $_POST['password'];
mysql_select_db('Sellte', $connection) or die('資料庫不存在');
$query = sprintf("select username,password from member where username=%s AND
password=%s",
GetSQLValue($username, "text"), GetSQLValue($password, "text"));
$result = mysql_query($query, $connection) or die(mysql_error());
if ($result)
{
$totalRows = mysql_num_rows($result);
if ($totalRows)
{
$_SESSION['Username'] = $username;
header("Location: login.php?id=".$username."");
}
}
else if ($_POST['username']= '' || $_POST['username']= '')
{
header("Location: login_form.php");
}
else
{
header("Location: login_form.php");
}
}
我希望做成 帳號密碼若是錯誤或為空 就直接導向 login_form.php
但是我測試結果他都卡在 不管有無輸入帳號密碼都不會導入login_form.php
則是直接導入 login.php 及 只要帳號輸入正確 密碼就算不填也都會導入 login.php
但是一直找不出哪裡錯誤 拜託各位高手解惑 : [
