title: Checkbox value match, but now show checked in checkbox
body: <p>Is there something wrong with my code :</p>
  
  <pre><code>if($q_ccd_chk == 'on')
  {
      if($q_front == 1)
      {
          echo '&lt;input type="checkbox" name="front" value="1" checked/&gt; Front';
      }
      if($q_back == 1)
      {
          echo '&lt;input type="checkbox" name="back" value="1" checked/&gt; Back';
      }
      if($q_fb == 1)
      {
          echo '&lt;input type="checkbox" name="fb" value="1" checked/&gt; FB';
      }
  }
  else
  {
      echo '&lt;input type="checkbox" name="front" value="1"/&gt; Front';
      echo '&lt;input type="checkbox" name="back" value="1"/&gt; Back';
      echo '&lt;input type="checkbox" name="fb" value="1"/&gt; FB';
  }
  </code></pre>
  
  <p>If value checkbox front and back value match, it will show checkbox with checked. But if the 3 of checkbox value match, its not show checked for all checkbox.</p>
