Question

我的代码出现问题，我希望它在忘记密码时通过电子邮件向用户发送用户名。

它的作用：

从数据库中检索用户信息
将HTML电子邮件发送给用户的电子邮件

它没有做什么：

发送到电子邮件时显示用户的登录用户名。

PHP代码如下页面＆＃34; forgot-username.php＆＃34;

<?php
require_once('../../Connections/localhost.php');
require('../../PHPMailer/PHPMailerAutoload.php'); 
if(isset($_POST) & !empty($_POST)){
$username = mysql_real_escape_string($_POST['username'], $localhost);
$sql = "SELECT * FROM database.users WHERE users.email = '$email'";
$res = mysql_query($sql, $localhost) or die(mysql_error());
$count = mysql_num_rows($res);
if($count == 1){
    $r = mysql_fetch_assoc($res);
    $username = $r['username'];
    $to = $r['email'];
    $subject = "Your Recovered Username";
    $message = file_get_contents("email_template.html");
    $headers = 'From: Your name <info@address.com>';
    if(mail($to,$subject,$message,$headers)){
        header('Location: username-sent.html');
    }else{
        echo "Failed to Recover your email, try again";
    }

}else{
    echo "email does not exist in database";
}
}

?>

一切都按预期进行，但用户名不会显示，而是＃34; $ username＆＃34;显示在电子邮件中。

有人请帮忙。提前谢谢。

Answer 1

file_get_contents（）函数不解析内容。因此，在将内容输入$ message后，您必须添加此行：

$ message = str_replace（'$ username'，$ username，$ message）;

我建议你用％USERNAME％之类的东西替换你的html中的$ username，你就这样使用它：

$ message = str_replace（'％USERNAME％'，$ username，$ message）;

Answer 2

首先，email_template.html是.html文件，您需要将其更改为.php文件。

其次，您将文件内容变为变量，您希望$username变量在同一范围内如何？

可能的解决方案是：

获取文件内容，然后将$username文件内容中的.html替换为$username值。

$message = file_get_contents("email_template.html");
$message = str_replace('$username', $username, $message);

Answer 3

您不能在HTML文档中使用PHP代码。 HTML文档中的任何PHP代码都将解析为字符串。

将'email_template.html'的文件扩展名更改为。腓：

email_template.php

请注意，现在您必须使用PHP echo来打印任何HTML。我建议阅读php的工作原理：http://www.php.net

使用PHP从HTML电子邮件中的数据库发送数据
