Answer 1

You can include a hidden form element.

 <input type="hidden" name="foo" value="bar" /> 

Answer 2

You can just use the hidden field . For example:

 <input type="hidden" name="your-field-name" value="your-field-value" /> 

This field will be available in your PHP script as $_POST['your-field-name']

Answer 3

As already mentioned, using hidden input fields is an option, but you can also use session . Thus, you do not need to post anything, the variables remain on the server and are not displayed in html.
