PHPmailer如何实现Ajax表单

Question

我在使用此联系表（它在其他主机中有效）的网站服务器上遇到问题，但在这个新主机中不工作。支持中心告诉我必须使用 phpmailer class 但我不知道如何实现它。

我将不胜感激任何帮助！谢谢

代码

Answer 1

Helena 在 If 的 Else 中（附件）你有： Reply-to header 仅以 \n 结尾什么时候应该以 \r\n 结尾你知道，所有 header 必须结束 \r\n

Answer 2

PHPMailer class 可以从这里下载：https://github.com/PHPMailer/PHPMailer（如果您在项目中使用它，也可以通过 Composer 下载）。

PHPMailer class 旨在简化 PHP 中发送电子邮件所需的代码。您在问题中引用的代码是我们在 class 之前使用的旧电子邮件发送方式的一个示例，例如 PHPMailer 存在。

简而言之，几乎所有您引用的代码都可以扔掉，代之以对 PHPMailer 的一次调用，以及为其设置参数的几行代码。

因此，扔掉您拥有的代码并使用 PHPMailer 文档中的示例之一重新开始。

文档中给出的示例应该足以让您入门；它们包括设置 to/from 地址、正文等，以及更复杂的内容，例如添加附件（同样，使用 PHPMailer 只需一行代码即可完成此操作）。 SO 上还有一大堆答案，举例说明了如何使用它。
