title: Trying to add a variable value to the existing Form POST vars
body: <p>I wish to add a flag value to indicate to the PHP routine, which functions to execute.</p>
  
  <p>I have tried various options and none seem to work.</p>
  
  <p>I am assuming it is a case of extending the serialised form vars, by adding my extra name/value pair.</p>
  
  <p>My latest attempt is</p>
  
  <pre><code>$.ajax etc etc
  data: $('#Form1').serialize().push( { 'phpFlag': 1 } ),
  </code></pre>
  
  <p>Which says I can not use 'push' on this object, which I thought was an array.</p>
  
  <p>Can anyone put me out of my misery.  I know I could have used a hidden form value.</p>
  
  <p>Thanks</p>
