  <pre><code>{!! Former::hidden('machine.status')
            -&gt;id('machine_status_hidden')
            -&gt;name('machine[status]')
            -&gt;value('damaged')
        !!}
  {!! Former::checkbox('machine.status')-&gt;name('machine[status]')
            -&gt;id('machine_status')
            -&gt;bind('machine.status')
            -&gt;label(' ')-&gt;text('finish?')
            -&gt;value('normal')
            -&gt;check($machine-&gt;status)!!}
  </code></pre>
