$root → appendChild($elem);
$elemtext = $doc → createTextNode($value);
$elem → appendChild($elemtext);
}
$myDoc = new Zend_Db_Xml_XmlContent($doc);
$about = new DOMDocument();
$abtRoot = $about → createElement("contacts");
$about → appendChild($abtRoot);
$myDoc → about = $about;
$db → saveNew($myDoc);
Since the php array objects are associative, that is, stored as a $key → $value
pair, you can see it is easy to create XML elements and attributes by just looping
through the $_POST array.
Modifying data in XCS
If you notice in the previous example, the add/member action adds a member's
profile into data and constructs an empty XML for ABOUT column. An empty
element < /contacts > is created and stored in XCS. When a logged-in user
browses a myContacts member and adds the member as a contact, the
add/contact action is invoked. The contactAction invokes the database method
addContact, which calls XCS's update function to update the entire xml
document. The db → addContact() method is explained in detail in the previous
database section.
ViewController
Similar to AddController, ViewController must not implement index action.
However, this controller should implement a __call() to handle dynamic actions
such as the following URL. This makes sure that any URL typing by the user is
handled appropriately.
http://localhost/view/123.
We discussed other actions such as search and display in detail in the previous
database section.
