PHP发送忘记密码的电子邮件

【中文标题】PHP发送忘记密码的电子邮件【英文标题】：PHP send email for Forgot Password 【发布时间】：2013-06-13 14:27:41 【问题描述】：所以我正在构建一个本地主机页面，它包含用户，所以我创建了一个忘记密码页面来在他们忘记密码时重置密码，并将随机密码更新到数据库中。
这是 ForgotPassword 的代码，我通过验证电子邮件而不是 ID 来使用它。
<h2 style="text-align:center;"> Forgot Password </h2>
<table align="center" bgcolor="#FFFFFF" height ="180">
<form action="doForgotPassword.php" method="post">
<tr><td align="right" >First Name</td>
<td><input type="text" name="first_name" /></td></tr>
<tr><td align="right" >Email</td>
<td><input type="text" name="email" /></td></tr>
<tr><td colspan="2" align="right"><input type="submit" value="Submit"/></td></tr>
</table> </form> </td></table>
这是 DoForgotPassword 的代码，我设法在数据库中更改了它，但无法通过电子邮件发送给用户。 我在这条线上遇到了麻烦
<?php
public function sendMail($email =$_POST['email'] , $id)
这是后面的代码。
$to = $email /* separated by comma for another email (useful if you want to keep records(sending to yourself))*/;
$subject = 'INSERT_SUBJECT_HERE';
$bound_text = "----*%$!$%*";
$bound = "--".$bound_text."\r\n";
$bound_last = "--".$bound_text."--\r\n";
$headers = "From: noreply@somewhere.com\r\n";
$headers .= "MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed; boundary=\"$bound_text\""."\r\n" ;
$message = " you may wish to enable your email program to accept html \r\n".
$bound;
$message .=
'Content-Type: text/html; charset=UTF-8'."\r\n".
'Content-Transfer-Encoding: 7bit'."\r\n\r\n".
'
<font size="3" color="#000000" style="text-decoration:none;font-family:Lato light">
<div class="info" Style="align:left;">

'."\n\n".
$bound_last;
$sent = mail($to, $subject, $message, $headers); // finally sending the email
$email =$_POST['email'];
function createRandomPassword()
$chars = "ABCDEFGHJKLMNOPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz0123456789";
$i = 0;
$pass = '' ;
while ($i <= 8)
$num = mt_rand(0,61);
$tmp = substr($chars, $num, 1);
$pass = $pass . $tmp;
$i++;
return $pass;
$pw = createRandomPassword();
$query = "UPDATE users SET password= SHA1('$pw') WHERE email = '$email' ";
$result = mysqli_query($link, $query);
if ($result)
$query3 = "SELECT * FROM users where email = '$email'";
$sql = mysqli_query($link, $query3) or die(mysqli_error());
$rownum = mysqli_num_rows($sql);
if(!$rownum )
echo "We can not find your email in our records";
这是生成的代码
if($result)
if(isset($_POST['id']))
$id = $_POST['id'];
sendMail($email, $id);
?>
【问题讨论】：
你真的得到了 $result 吗？ 有错误信息吗？你有什么迹象表明有问题？电子邮件是否发送但从未到达用户的收件箱？ 您不应该发送密码。您应该向他们发送更改密码的链接。 是的。邮件已发送但未到达收件箱，我什至尝试使用其他邮件但无济于事。 不需要 $this-> （用于使用类结构（我经常使用类，所以会感到困惑））除了它应该可以工作 ^o）之外，您是否设置了$id？
【参考方案1】：
这是我在当前应用程序上发送的任何邮件所使用的功能（敏感信息已删除），很容易弄清楚您需要做什么，但提供的 cmets 应该可以回答一些问题，
这个函数允许 html 格式，这应该可以让你使它变得漂亮 :D
public function sendMail($email, $company, $location, $startAt, $endAt, $date, $userId,$duration)
$to = $email; /* '. ','; separated by comma for another email (useful if you want to keep records(sending to yourself))*/;
$subject = 'INSERT_SUBJECT_HERE';
$bound_text = "----*%$!$%*";
$bound = "--".$bound_text."\r\n";
$bound_last = "--".$bound_text."--\r\n";
$headers = "From: noreply@somewhere.com\r\n";
$headers .= "MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed; boundary=\"$bound_text\""."\r\n" ;
$message = " you may wish to enable your email program to accept HTML \r\n".
$bound;
$message .=
'Content-Type: text/html; charset=UTF-8'."\r\n".
'Content-Transfer-Encoding: 7bit'."\r\n\r\n".

这绝对可以工作（只要您替换 INSERT_... 等），除了我不能立即看到您的代码有任何问题之外，我真正推荐的唯一一件事是检查您的应用程序错误日志，它应该如果有任何问题，请告诉您。
另外检查你的 php ini 文件看看 sendmail 是否被激活:)
问候史蒂夫。

所以你的新代码应该是这样的；
<?php
$email =$_POST['email'];
public function sendMail($email, $userId)
$to = $email;
$subject = 'Password Reset';
$bound_text = "----*%$!$%*";
$bound = "--".$bound_text."\r\n";
$bound_last = "--".$bound_text."--\r\n";
$headers = "From: noreply@somewhere.com\r\n";
$headers .= "MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed; boundary=\"$bound_text\""."\r\n" ;
$message = " you may wish to enable your email program to accept HTML \r\n".
$bound;
$message .=
'Content-Type: text/html; charset=UTF-8'."\r\n".
'Content-Transfer-Encoding: 7bit'."\r\n\r\n".

$this->sendMail($email, $userId); /*does it need to be in a class for $this->? or can you call functions within the php page without?*/
?>
----- 编辑 ------
好的，函数调用应该是sendMail($variableOne, $variableTwo)
如果您在 sendMail 函数开始时删除变量，那么它应该是 function sendMail($email)/*code*/ 并尝试（发送邮件需要电子邮件）

我最近改造了这个功能以允许使用Gmail SMTP，如果你查看这个Page from RamDev (Check the post by Stephen Penn)，我会解释步骤以及我构建的功能，它可以帮助你了解通过SMTP发送邮件的过程。
再次感谢，

【讨论】：
我是否将其放在我的 if($result) 中？或者另一个函数然后在里面回显它？抱歉，我对 php 很陌生，尤其是电子邮件 是的，只需将代码输入到 php 页面上的任意位置，然后在 if($result) $this->sendMail($parameterOne, $parameterTwo,etc) 应该放在 里面吧？但它在 public function sendMail($email, $company, $location, $startAt, $endAt, $date, $userId,$duration) 语法错误 能否在编辑中发布错误消息和新的代码行？ 语法错误：内联 html 后的意外公共该行是公共函数 sendMail($email, $id)【参考方案2】：<?php
include "connection.php";
echo "<br>";
if(isset($_POST['submit']))
$email = $_POST['email'];
$check = mysql_query("select * from register where email = '$email' ");
$find = mysql_num_rows($check);
if($find)
function makepassword($length)
$validCharacters = "ABCDEFGHIJKLMNPQRSTUXYVWZ123456789";
$validCharNumber = strlen($validCharacters);
$result ="";
for ($i = 0; $i < $length; $i++)
$index = mt_rand(0, $validCharNumber - 1);
$result .= $validCharacters[$index];
return $result;
$random_password = makepassword(10);
//echo $password_final = md5($random_password);
//echo "update set pass ='$random_password' where email = '$email'"; exit;
$final_result = mysql_query("update register set pass ='$random_password' where email = '$email' ");
if($final_result)
echo "Your Password is:".$random_password;
else
echo "Email Not Found";
?>
