未定义索引：电子邮件错误消息的评论
更改此行：
<input type="email" name="name" placeholder="name@something.com"/ required>
使用（反勾号）：
您甚至可以删除引号：（但倒勾更好）
回复：未定义索引：
您错误地命名了用于在HTML中保存电子邮件地址的输入
<input type="email" name="name" placeholder="name@something.com"/ required>
换成
<input type="email" name="email" placeholder="name@something.com"/ required>
注意name=“email”
您在HTML中为字段指定的名称控制$\u POST数组中使用的字段名。首先，$\u POST
是一个字符，必须为大写。您有if（！empty（$\u post））{
将其更改为if（！empty（$\u post））{
这很可能是“a”或者是实际的问题。我不能测试你的全部代码，但一定要从那开始。据我所知，你的其他代码对我来说似乎没问题，除了你使用的是一个不推荐的mysql\uuuu
function.msql\u connect to mysql\u connection我还没有注意到@JoniSalmi很好。我注意到你用发布的c编辑了你的问题注意/回答（刚才）。现在有什么问题？@Fred ii-工作很好！非常感谢你帮助我：）
