Question

我创建了一个程序，可以在特定条件下向我的数据库中的所有电子邮件发送电子邮件。然而，我现在的问题是，我需要在连接到我的另一个php页面的电子邮件的消息中创建一个链接。在该链接中，我需要将电子邮件地址传递给查询字符串，但我从未创建变量$ email，因为我觉得我的while循环没有必要。关于如何解决这个问题的任何建议？

http：//localhost/unsubscribe.php？e = $ email'＆gt;点击此处取消订阅

<?php

$subject = "New Sales";
$message = "25% off any item of your choice! <br>
        <a href=’http://localhost/unsubscribe.php?e=$email'>click here to unsubscribe</a>"; 

$headers = "From: email@yourdot.com";

 //create connection
$servername = "localhost";
$username = "root";
$password = "student";
$dbname = "db1";

// Create connection
$mysqli = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
} 



  $result = $mysqli->query("SELECT emailAddress FROM members WHERE subscribe = 'YES' ");


    while ($row = $result->fetch_object()) {
    if (isset($row->emailAddress)) {
        mail($row->emailAddress,$subject, $message, $headers);

}

}
echo "Email has been sent!"; 
?>

任何建议都有帮助，但我不想摆脱while循环，因为在我看来这是最好的选择。如果有更好的选择，请通知我。请保持对我的轻松。我是个菜鸟。

Answer 1

如果你只是想通过url传递变量，你可以像这样传递：

  <a href=’http://localhost/unsubscribe.php?e=<?php echo $email; ?>'>click here to unsubscribe</a>";

或

 <a href='unsubscribe.php?e=".$email."'>click here to unsubscribe</a>

Answer 2

如果条件在while循环中，请移动电子邮件，如下所示：

while ($row = $result->fetch_object()) {
    if (isset($row->emailAddress)) {
        $message = "25% off any item of your choice! <br>
        <a href=’http://localhost/unsubscribe.php?e=$row->emailAddress'>click here to unsubscribe</a>";
        mail($row->emailAddress,$subject, $message, $headers);
    }
}

希望它有所帮助！
