What's the point of having hidden input in HTML? What are common uses for this?

Question

I don\'t see the benefit of having hidden input? If you set the value of the hidden input why not just use that value at the point where you reference this hidden input?

Answer 1

For example, if you have a form to edit an entity from you data model, you could use an hidden input to place the id of the entity you are updating, since you don't want to have this value put in the text input field to be posted back to the server. the hidden field will be posted to the server as if it were part of your form.
