How to send hidden data
提问by user2556079
I have a form(like the one below for example) where I type data, but I also want to send data which are not directly entered by the user, for example a generic Id(for a user in this case)
我有一个表单（例如下面的表单），我在其中输入数据，但我也想发送用户未直接输入的数据，例如通用 Id（在这种情况下为用户）
<form name="input" action="" method="post">
Username: <input type="text" name="user">
<input type="submit" value="Submit">
</form>
Don't know if I have been clear enough, I hope so.
不知道我说的够不够清楚，希望如此。

try a hiddeninput:
尝试hidden输入：
<input type="hidden" value="foo" name="user_id" />
The user can't see it, but remember that such inputs can be spoofed and need to be validated on the server just like any other input.
用户看不到它，但请记住，此类输入可以被欺骗，并且需要像任何其他输入一样在服务器上进行验证。
