在表单中添加验证码。它可以是简单的，也可以是复杂的。您可以添加reCaptcha，甚至可以自己滚动 通常，在显示表单之前，可以生成问题并将答案存储在会话中。然后让他们输入答案。发布后，检查会话中存储的值是否匹配
不过，更简单的是，您还可以将required添加到消息表单输入中，以确保它不是空的，这是您最初的查询。但是您仍然应该使用某种验证码。消息可能包含一些带有hiiden等属性的html，或者一些不可打印的字符，因此您不能在修剪后仅检查消息是否为空。您的验证似乎没有任何用处-您设置了$err..='。。。有时给出口打电话，有时不打。如果你退出-对你设置的邮件不做任何处理，但如果你不退出，它只发送电子邮件。我不想使用验证码。我想学习服务器端脚本。CAPTCHA工作在服务器端，你需要用PHP编写脚本。如果你想学习，试试这个！我同意验证码在这里是件好事。OP可以使用不可见的recaptha，所以用户不需要填充它。。剩下的呢？@tejal为消息添加出口。。但我建议退出并在出现错误时重定向。。
