Ordering attributes within a node

From Achievo/ATK Wiki

Ordering attributes within a node

If you have an atkNode, attributes (i.e. database columns) appear in the order in which they are added via atkNode::add().

If you have an atkMetaNode (or derived class), fields appear in the order in which they appear in the database. To control the order in which attributes appear within a node (i.e. on a "page"), use atkMetaPolicy::setOrder(), atkMetaPolicy::setIncludes() or the $order argument to either atkMetaNode::add() or atkMetaPolicy::add(). If you don't have access to an atkMetaPolicy, use atkMetaNode::setAttributeOrder().

Examples

With atkMetaPolicy:

public static function meta(atkMetaPolicy $policy) 
{
  $policy->add("invoice_start_date", "atkDateAttribute");
  $policy->add("invoice_end_date", "atkDateAttribute");
 
  $policy->setOrder(array(
    "invoice_start_date",
    "invoice_end_date"
  ));
}

Using atkMetaAttributeModifier attribute modifiers:

public static function meta(atkMetaPolicy $policy) 
{
  // Make sure that field1 appears after field 2
  $policy->get("field1")->insertAfter("field2");
 
  // Make sure the remark field appears at the bottom.
  $policy->get("remark")->insertAtBottom();
}
 
See the [http://www.atk-framework.com/docs/atk/trunk/atk/meta/atkMetaAttributeModifier.html atkMetaAttributeModifier] API docs for more possibilities on reordering.

Independently ordering attributes on the "admin" and "view" pages

If you want your attributes to appear in one order in the "admin" (list) page, and in another in the "view" (detail) page, you can do something like the following to ensure that the "name" attribute will appear before the "email" attribute of "view" pages:

  public function action_view($handler) {
    $this->setAttributeOrder("name", 10);
    $this->setAttributeOrder("email", 20);
    $this->attribSort();
    $handler->action_view($handler);
  }

(Note that where they will appear in relation to the other attributes is dependent on the "order" value of the other attributes.)
