我想知道是否有人可以幫助我。密碼重置鏈接有效日期
我一直在對「密碼重置」過程進行相當多的研究,並且從我發現的教程之一中,我已經能夠將以下代碼放在一起提供此功能。
忘記密碼
<?php
// Connect to MySQL
$c = mysql_connect("host", "user", "password");
mysql_select_db("database", $c);
// Was the form submitted?
if ($_POST["ForgotPasswordForm"])
{
// Harvest submitted e-mail address
$emailaddress = mysql_real_escape_string($_POST["emailaddress"]);
// Check to see if a user exists with this e-mail
$userExists = mysql_fetch_assoc(mysql_query("SELECT `emailaddress` FROM `userdetails` WHERE `emailaddress` = '$emailaddress'"));
if ($userExists["emailaddress"])
{
// Create a unique salt. This will never leave PHP unencrypted.
$salt = "KEY";
// Create the unique user password reset key
$password = md5($salt . $userExists["emailaddress"]);
// Create a url which we will direct them to reset their password
$pwrurl = "phpfile.php?q=" . $password;
// Mail them their key
$mailbody = "Dear user,\n\nIf this e-mail does not apply to you please ignore it. It appears that you have requested a password reset at our website \n\nTo reset your password, please click the link below. If you cannot click it, please paste it into your web browser's address bar.\n\n" . $pwrurl . "\n\nThanks,\nThe Administration";
mail($userExists["emailaddress"], "", $mailbody);
echo "Your password recovery key has been sent to your e-mail address.";
}
else
echo "No user with that e-mail address exists.";
}
?>
重置密碼
<?php
// Connect to MySQL
$c = mysql_connect("host", "user", "password");
mysql_select_db("database", $c);
// Was the form submitted?
if ($_POST["ResetPasswordForm"])
{
// Gather the post data
$emailaddress = mysql_real_escape_string($_POST["emailaddress"]);
$password = md5(mysql_real_escape_string($_POST["password"]));
$confirmpassword = md5(mysql_real_escape_string($_POST["confirmpassword"]));
$q = $_POST["q"];
$passwordhint = $_POST["passwordhint"];
// Use the same salt from the forgot_password.php file
$salt = "KEY";
// Generate the reset key
$resetkey = md5($salt . $emailaddress);
// Does the new reset key match the old one?
if ($resetkey == $q)
{
if ($password == $confirmpassword)
{
// Update the user's password
mysql_query("UPDATE `userdetails` SET `password` = '$password', `passwordhint` = '$passwordhint' WHERE `emailaddress` = '$emailaddress'");
echo "Your password has been successfully reset.";
}
else
echo "Your password's do not match.";
}
else
echo "Your password reset key is invalid.";
}
?>
現在,我想補充一點,我發送給用戶的鏈接的定時到期。我一直在看Stackoverflow社區和其他許多人的帖子,但我一直沒能找到我一直在尋找的東西。
我只是想知道是否有人可以幫助我,請給我一點指導,告訴我如何完成此任務。
非常感謝。

嗨,不,我只是在我將腳本放在一起的時候使用它。然後他們被改變去處理一個文件。親切的問候 – IRHM 2012-01-14 16:37:37
