title: Laravel validation rules for related checkboxes
body: <p>In my form I have a couple checkboxes and i want at least one of them (or both) to be checked before submitting my form. My input checkboxes are named <code>car</code> and <code>bike</code>. In my controller i am validating my request </p>
  
  <pre><code>$this-&gt;validate($request, [
              'content'=&gt; 'required',
              'title' =&gt; 'required',
              'car | bike' =&gt; 'required', //this is not correct.
          ]);
  </code></pre>
  
  <p>What i couldn't figure is the statement that allows me to do the validation above</p>
