Question

我对PHP知之甚少。我聘请了一位自由职业者为我创建这个，然后在我注意到一个问题后，他的帐户在freelancer.com上关闭了。所以我再也无法与他沟通了。所以任何帮助都非常感激。他为我创建了一个系统，可以自动将数字文件通过电子邮件发送给eBay客户。它使用PayPal IPN的数量和价格信息来做到这一点。我的所有数字文件都是一次性使用。因此，一旦在eBay上购买文件，它就会通过电子邮件发送给客户，然后被丢弃。当客户订购数量为1时，系统运行良好。

问题是当客户订单超过1时.2个情况发生：例如，如果客户订购了2个数字文件，请说“XB1.pdf”和“XB2.pdf”。方案1他们将在电子邮件中获得“XB1.pdf”，有时在第二封电子邮件中获得“XB2.pdf”，但电子邮件中充满了一堆giberish（我将电子邮件内容发布到ipn.php的底部）内容如下）。场景2有时它们会收到2封电子邮件但两者都只包含“XB1.pdf”而不包含“XB2.pdf”。你能看一下代码，看看你是否能发现问题？这是ipn.php文件的内容，我相信这就是问题所在。

Answer 1

问题是代码在每个循环上附加到$email_message。第一次通过这很好;第二次通过一组新的标题和数据附加到原始电子邮件消息，这会破坏事情。

要更详细地查看问题，请按照代码进行操作。该行设置了msg的初始内容：

$email_message = $query2_s['email_message'];

内容来自数据库，从您包含的输出中我们可以看到它：

在这里写下你想要的任何东西。这将是发送的电子邮件的正文。

接下来，代码选择要处理的记录，并开始迭代它们。它通过将一些数据附加到上面准备的现有内容来构造消息：

$email_message .= "This is a multi-part message in MIME format.\n\n"
// etc, there are several lines of headers added here

最后，使用在最后几个步骤中构建的内容发送邮件：

$ok = @mail($email_to, $email_subject, $email_message, $headers);

一切都很好，第一封邮件的内容很好。但是，如果有多个项目，代码现在循环并再次运行下一条记录。这就是问题所在 - $email_message不会重置为空字符串，或者最初＆＃34;写下你想要的任何东西......＆＃34;来自数据库的消息。而是将第二组标题添加到现有消息内容中：

$email_message .= "This is a multi-part message in MIME format.\n\n"
// etc, appends new stuff to existing $email_message

$email_message现在包含邮件1的标题和内容，其中附有邮件2的标题和内容。

要避免这种情况，请使用不同的变量名称。例如，而不是这一行：

$email_message = $query2_s['email_message'];

使用：

$email_prefix = $query2_s['email_message'];

然后代替：

$email_message .= "This is a multi-part message in MIME format.\n\n" .

使用：

$email_message = $email_prefix . "This is a multi-part message in MIME format.\n\n" .

这种方式$email_message是在每次迭代时从头开始创建的，使用数据库中的$email_prefix并附加其余信息。
