Code

function entityconnect_form_alter(&$form, &$form_state, $form_id) {
  $child = isset($_REQUEST['child']);

  // We can get the cid two different ways
  // first we try the $_REQUEST param.  if we do not getting it from there we
  // try the arg(3) if we are on a add form.  Also if we are on an add form we
  // know that we are a child page.

    }
  }

  // If this form is a child form let's add alter for that purpose
  // Note that we are doing this here becuase when we retrun to a form it gets
  // rebuilt so this will get caught in the rebuilt.
