title: How to add array by hidden type in cake php?
body: <p>I want to carry an array from one form to another form by hidden data type in cake php.
  I don't know how many number will come. So, I can not know how many number.
  e.g.</p>
  
  <p>Example in PHP:</p>
  
  <pre><code>foreach($rNo as $no){
      echo "&lt;input type='hidden' name='no[".$no."]' value='".$no."'&gt;";
  }
