Q:

Secure Hidden form Data $_POST

I was just fiddling around in Chrome and realized that a hidden form element can be changed by a user in the Chrome inspector. 

As you can see in the picture above any user can go in and edit the form in Chrome and then submit the form. 
I'm curious if there is a way around this such as a more secure way of sending data to my files that I do not want to be changed by the user. 

A:

Easy, don't put it in your form.  So where can you put it?  Store it in a session.
