我们有一个提交表格的网站，通过以下代码（通过下面的代码）;为什么PHP Mailer不总是发送电子邮件？
发送一个测试的邮件，自己之前插入到MySQL只是让我知道PHP邮包的工作，它总是在我所有的测试确实
然后从表格中的所有数据插入到MYSQL（这也总是有效）
通过PHP邮件发送另一封电子邮件与他们提交的所有信息。我希望它以纯文本格式（这仅适用于大约80％的时间）。
发生了什么事是，有时人们提交和它的一切，但有时它只做步骤1和2。所以有时候，有些事情似乎在某处断裂。我觉得这可能是某些标点符号的问题，但不确定。就像在$复制字段中一样，人们可以输入任何他们想要的东西。不确定是否有某些标点可能会打破第二封电子邮件程序。
注意：每次有人提交时，都会将它们带到request-success.php页面。但它并不总是发送来自步骤3的电子邮件。
如果有人看到有改进的地方或者错误的东西，请分享。这让我疯狂。
