PHP send email for Forgot Password
提问by Ren
So I am building a localhost page, and it contains users, so I created a forgot password page to reset password if they forget, and to update the randomized password into the database.
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重置密码，如果他们忘记了，并将随机密码更新到数据库中。
This is the codes for ForgotPassword, and I use it by validating email and not ID.
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" width="500" height ="180">
<form action="doForgotPassword.php" method="post">
<tr><td align="right" height="50" width="200">First Name</td>
<td><input type="text" name="first_name" /></td></tr>
<tr><td align="right" height="50">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>
And this is the codes for DoForgotPassword, I managed to change it in the database but not able to email the user. I am having trouble at this line
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)
This is the rest of the codes after it.
这是它之后的其余代码。
{
$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: [email protected]\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".

'."\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(!$rownum ) {
echo "We can not find your email in our records";
}
}
And this is the resulting code
这是结果代码
if($result){
if(isset($_POST['id'])){
$id = $_POST['id'];
sendMail($email, $id);
}
}
?>

This is the function I use for any mail I do on my current application (sensitive info removed), it's pretty easy to figure out what you need to do but the comments provided, should answer some questions,
这是我用于在当前应用程序上执行的任何邮件的功能（删除了敏感信息），很容易弄清楚您需要做什么，但提供的评论应该回答一些问题，
This function allows for html formatting which should allow you to make it prettyful :D
此功能允许使用 html 格式，这应该可以让您使其变得漂亮：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: [email protected]\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".

<!-- here is where you format the email to what you need, using html you can use whatever style you want (including the use of images)-->
<BODY BGCOLOR="White">

'."\n\n".
$bound_last;
$sent = mail($to, $subject, $message, $headers); // finally sending the email
}
This should definitely work (as long as you replace INSERT_... etc), other than that I can't see anything wrong with your code immediately, only thing i can really recommend Is checking your applications error logs, it should give you an indication if anything is wrong.
这绝对可以工作（只要您替换 INSERT_... 等），除此之外我无法立即看到您的代码有任何问题，我唯一真正推荐的是检查您的应用程序错误日志，它应该给您一个指示是否有任何问题。
Else check your php ini file to see if sendmail is activated :)
否则请检查您的 php ini 文件以查看是否已激活 sendmail :)

so your new code should be along the lines of;
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: [email protected]\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".

ok the function call should be sendMail($variableOne, $variableTwo)
好的函数调用应该是 sendMail($variableOne, $variableTwo)
if you delete the variables at the start of the sendMail function so it should be function sendMail($email){/*code*/}and try that (the email is required to send the mail)
如果您删除了 sendMail 函数开头的变量，那么应该这样做function sendMail($email){/*code*/}并尝试这样做（发送邮件需要电子邮件）

I have recently remodeled this function to allow for use of Gmail SMTP, If you check out this Page from RamDev (Check the post by Stephen Penn), I explain the steps as well as the function i built, It may help you understand the process of mail through SMTP.
我最近改造了这个功能以允许使用 Gmail SMTP，如果你从 RamDev 查看这个页面（查看 Stephen Penn 的帖子），我解释了步骤以及我构建的功能，它可能会帮助你理解这个过程邮件通过 SMTP。
Thanks again,
再次感谢，
