How to send hidden data

Question

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)

<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.

Use input `hidden`: http://www.w3schools.com/jsref/dom_obj_hidden.asp — Jonathan Naguin, Jul 06 '13 at 18:13

try a hidden input:

<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.

Be careful because the form does not send the hidden input or any input unless the tag contains the name field – Andreas Panagiotidis Dec 08 '22 at 18:45
