    print $query->checkbox(-name=>'checkbox_name',
			   -checked=>'checked',
			   -value=>'ON',
			   -label=>'CLICK ME');


	-or-


    print $query->checkbox('checkbox_name','checked','ON','CLICK ME');

checkbox is used to create an isolated checkbox that isn't logically related to any others.

Parameters:
  • The first parameter is the required name for the checkbox (-name). It will also be used for the user-readable label printed next to the checkbox.

  • The optional second parameter (-checked) specifies that the checkbox is turned on by default. Synonyms are -selected and -on.

  • The optional third parameter (-value) specifies the value of the checkbox when it is checked. If not provided, the word ``on'' is assumed.

  • The optional fourth parameter (-label) is the user-readable label to be attached to the checkbox. If not provided, the checkbox name is used.

    • The value of the checkbox can be retrieved using: 

        $turned_on = $query->param('checkbox_name');

    JAVASCRIPTING: checkbox recognizes the -onClick parameter. See checkbox_group for further details.
