You can use:

Input::has('secure') like that:

If (Input::has('secure')){ $secure = 1; (Checkbox is checked) }else{

$secure = 0; (Checkbox is not checked) }

If I save the form with the checkbox ticked it saves as a 1 in the database and if I save the form with the checkbox not ticked the it saves as a NULL instead of a 0.

And I added

"secure" => Input::get("secure")

to

if($form->isValidForAdd()){
					Resource::create([
						"name" => Input::get("name"),
						"pattern" => Input::get("pattern"),
						"target" => Input::get("target"),
						"secure" => Input::get("secure")
					]);

and I changed

{{ Form::checkbox('secure', 'yes') }}

to

{{ Form::checkbox('secure', 1, true) }}
