CREATING A HIDDEN FIELD 

	print $query->hidden(-name=>'hidden_name',
			     -default=>['value1','value2'...]);


		-or-


	print $query->hidden('hidden_name','value1','value2'...);

hidden produces a text field that can't be seen by the user. It is useful for passing state variable information from one invocation of the script to the next.

Parameters:
  • The first argument is required and specifies the name of this field (-name).

  • The second argument is also required and specifies its value (-default). In the named parameter style of calling, you can provide a single value here or a reference to a whole list

    • Fetch the value of a hidden field this way: 

         $hidden_value = $query->param('hidden_name');

    Note, that just like all the other form elements, the value of a hidden field is ``sticky''. If you want to replace a hidden field with some other values after the script has been called once you'll have to do it manually: 

         $query->param('hidden_name','new','values','here');
