Php 主页上出现的联系人表单响应

我有一个网页与锚和联系形式是最后一部分。我在下面有一条回音信息，一旦我加载页面，它就会出现在那里。有没有办法让它只在邮件发送时出现？此外，如果页面已加载，它会自动发送邮件。谢谢

表单的代码

将php代码放在表单之外，然后再试一次。“邮件”之前的“@”是否会抑制任何错误代码？@user2983295:不，它会：“@”操作符抑制错误消息，这是一个教训，”->；因此，说“@mail”意味着“发送电子邮件。如果你不发送，就不要在意，继续吧”。@briosheje但它怎么能比我的其他项目更有效，而不是这个项目呢/@user2983295:可能有很多原因导致mail（）函数无法工作。检查：并检查您的php.ini是否配置正确：）有时需要手动设置“mailfrom”和其他一些东西，例如端口！更新：检查这个，例如：（请注意这些东西通常取决于您安装的web服务器、防火墙等）好的，现在消息根本不显示。有什么想法吗？试着删除“@”并将此代码置于顶部：错误报告（E_ALL）；然后你可以试着在php代码前面加上：（对不起：/
