title: How to set place holder copy in date select menu in CakePHP
body: <p>I am using CakePHP 1.3 to create a select menu for date of birth (as below). I can set the default starting values as either blank or a selected date, but ideally I would like to have DD-MM-YYYY as the starting displayed values:</p>
  
  <pre>
  echo $form->input('dob', 
      array(
      'before' => '', 
      'between' => '', 
      'after' => '', 
      'label' => false, 
      'divider' => false, 
      'monthNames' => false, 
      'selected' => false, 
      'empty' => true, 
      'dateFormat' => 'DMY', 
      'minYear' => date('Y') - 70,
      'maxYear' => date('Y') - 16,
      'error' => array('wrap' => 'div', 'class' => 'error-copy')
      ));
  </pre>
  
  <p>What I get:</p>
  
  <p><img src="https://i.stack.imgur.com/NDKAO.png" alt="Date of birth select menus"></p>
  
  <p>What I would like:</p>
  
  <p><img src="https://i.stack.imgur.com/Chiwi.png" alt="Placeholder DD MM YYYY copy"></p>
  
  <p>Thank you</p>
