我想在发送和显示此消息时隐藏表单动态决定何时打印表单或打印感谢消息？因为您有一个
if（isset（$\u POST['submit']）{…}
，然后只需将
html代码包装在
else{…}
block，提交表单后它将不显示表单……或者使用ajax/js。是的，只需回显您想要的消息并在其下方添加一个出口，然后您可以执行
if（isset（$\u POST['submit']）&&$errors=''）{……您的表单…}
请原谅我的无知，但我不明白如何在您向我指出的示例中构造PHP代码和HTML表单。刚才我编辑了答案。。请查收。！隐藏表单而不发送朋友？如果（空（$errors））{$asunto=“”；$message=“Usuario:.$\u POST['name']”。电子邮件：.$\u POST['mail']。.Telefono.$\u POST['phone']。$\u POST['message']；$destino=”contacto@example.com“；$remotente=”发件人：contacto@example.com“邮件（$destino、$asunto、$message、$remotente）；未设置（$_POST['submit']）；$errors.=“\n感谢联系我们。”；}$errors.=“\n感谢联系我们。”如果（$errors==“感谢联系我们”，请检查此条件。）
