php电子邮件发送副本

出于某种原因，我用来发送联系人表单的代码正在向我的邮箱发送一个副本。有人能帮我吗？我需要底部的if语句，以便我的jquery显示错误和成功的消息，代码正常工作只是发送了一个副本。我缺少什么吗

我不是一个php编程高手，但我很清楚我在做什么：）

抱歉，这次发送邮件时出错。

尝试删除错误抑制操作符（

@

），您可能会得到有关其不工作原因的更多详细信息。我认为错误不在PHP

邮件

函数中，我认为您的ajax请求更有可能被发送两次。。您能告诉我们如何触发ajax调用吗？此外，打开开发工具并观察网络流量，它将显示正在发送的呼叫。。因此，您将看到是否有两个ajax调用您还应该在这一行

$message.='Name:'上将连接运算符
=
更改为
=
$_请求['name']。“
