Didn't work. Anyway it's strange, when tributary is false, both radio buttons (one for true value and another for false value) are unchecked but, when tributary is true, false radio button is checked.

I found this page when looking for a solution to marking 1 of many radio buttons as true depending on what was saved in the database. I figured out a solution shortly after and thought I would add my solution if anyone else finds this page as I did. You can't use if statements to set values for the different options, plus this method is faster I believe.

{{ Form::radio('name', 'value1', ($var->option == 'value1') }} Value1
{{ Form::radio('name', 'value2', ($var->option == 'value2') }} Value2
{{ Form::radio('name', 'value'3, ($var->option == 'value3') }} Value3

this results in giving only the stored value a 1 which makes that option/value active.

The title says 'Form Model Binding and Radio Buttons' but I don't see any form model binding here! I was expecting to find some way of populating several radio buttons using form model binding...

I agree. No Form Model Binding on that solution.

I fixed it by using a ['checked' => 'checked'] array as a fourth argument in Laravel 5.3

{{ Form::label('visible', 'Visibility') }}

            @if ($category->visible == '1')
                {{ Form::radio('visible', '1', true, ['checked' => 'checked']) }} Yes
                <br />
                {{ Form::radio('visible', '0', false, []) }} No
            @else
                {{ Form::radio('visible', '1', false, []) }} Yes
                <br />
                {{ Form::radio('visible', '0', true, ['checked' => 'checked']) }} No
            @endif
