Question

不确定发生了什么，但它突然停止工作...... 我可以输入电子邮件和用户名（我知道凭据是正确的）并收到消息，它不会找到任何匹配的详细信息......

forgotpassword.php的内容：

<?php
require_once("users.inc");

$PAGE_TITLE = "Forgotten Password";

include $PHP_USERS_HEADER_FILE; 

?>

<h3>Forgot Your Password?</h3>

<p>If you've forgotten your password, just enter the username and email address that you registered with, and your password will be emailed to you immediately.</p>



<form method="post" action="emailpassword.php">
  <p><b>Your Username: </b>
  <input type="text" name="username" size="35" />
  </p><p>
  <b>Your Email Address: </b>
  <input type="text" name="email" size="35" />
  </p>
  <input type=submit value="Submit" />
</form>

emailpassword.php的内容：

<?php
require_once("users.inc");

$PAGE_TITLE = "Forgotten Password";

connect_to_users_db();

$password = fnRandomPassword(8);
$encrypt_pwd = md5($password);

$sql = "UPDATE users SET password='$encrypt_pwd' WHERE email='".$_REQUEST['email']."' AND username='".$_REQUEST['username']."'";
$query = mysql_query($sql);

$sql1 = "SELECT email, username, password FROM users WHERE email='".$_REQUEST['email']."' AND username='".$_REQUEST['username']."'";
$query1 = mysql_query($sql1);
if ($query1 && (mysql_num_rows($query1) > 0)) {

  while (list($email,$username) = mysql_fetch_row($query1)) {
    mail($email, "Your Password", "Below is the username and password information you requested.\n\nUsername: '$username'\nPassword: '$password'.\n\n","From: $WEB_MASTER <$WEB_MASTER_EMAIL>\n");

}
}


include $PHP_USERS_HEADER_FILE; 

?>

<h3>Forgot Your Password?</h3>

<?

echo "<p>";

//if ($query && mysql_num_rows($query) > 0) { 
if (mysql_affected_rows() > 0) { 

?>

<p>We've emailed your password. You should receive it within a minute. If you don't, please send mail to the <a href="mailto:<?=$WEB_MASTER_EMAIL?>"><?=$WEB_MASTER?></a>.</p>

<?php

} else { 

?>

<p>We could not find an email and username corresponding with the email address and username you entered. Perhaps you registered with a different email address/username. Use the form below to try again.</p>



<form method="post" action="emailpassword.php">
  <p><b>Your Username: </b>
  <input type="text" name="username" size="35" />
  </p><p>
  <b>Your Email Address:</b>
  <input type="text" name="email" size="35" />
  </p>
  <input type="submit" value="Submit" />
</form>


<p>If you believe you have not registered before, you are welcome to sign up now with the following form:</br>
      <?php include 'fragments/requestaccont.htm';?>

<?php

}

?>

这里有什么过时的编码吗？

Answer 1

它停止工作，因为您更改了检查查询的行。现在它将通过电子邮件发送新密码并显示“未找到”的密码。消息。

您使用的是mysql_affected_rows()，但最后一个查询是SELECT查询，该查询不会影响行。改变这一行：

if (mysql_affected_rows() > 0) {

进入这一行：

if ($query1 && (mysql_num_rows($query1) > 0)) {

另请注意Doon，mysql_*已被弃用。

Forgotpassword函数无法正常工作，sql，php
