title: CakePHP: how to get recently created auto-incremented field
body: <p>I have a user submit a field to the database, it validates, and makes the entry.  The primary key of this new row is auto-incremented.  </p>
  
  <p>The user then gets to another form where that newly created field is required.</p>
  
  <p>Can anyone shed any light on this problem?</p>
  
  <p>Thanks in advance!</p>
