Class XmlView

A view class that is used for creating XML responses.

By setting the '_serialize' key in your controller, you can specify a view variable that should be serialized to XML and used as the response for the request. This allows you to omit views + layouts, if your just need to emit a single view variable as the XML response.

In your controller, you could do the following:

$this->set(['posts' => $posts, '_serialize' => true]);

When the view is rendered, the $posts view variable will be serialized into XML.

Note The view variable you specify must be compatible with Xml::fromArray().

You can also define '_serialize' as an array. This will create an additional top level element named <response> containing all the named view variables:

$this->set(compact('posts', 'users', 'stuff'));
$this->set('_serialize', true);

The above would generate a XML object that looks like:

<response><posts>...</posts><users>...</users></response>

You can also set '_serialize' to a string or array to serialize only the specified view variables.

If you don't use the _serialize key, you will need a view. You can use extended views to provide layout like functionality.

A basic example getting the return value of the controller action:

$variables = $this->requestAction('/articles/popular');

A basic example of request action to fetch a rendered page without the layout.

You can pass POST, GET, COOKIE and other data into the request using the appropriate keys. Cookies can be passed using the cookies key. Get parameters can be set with query and post data can be sent using the post key.

$vars = $this->requestAction('/articles/popular', [
  'query' => ['page' => 1],
  'cookies' => ['remember_me' => 1],
]);

Sending environment or header values

By default actions dispatched with this method will use the global $_SERVER and $_ENV values. If you want to override those values for a request action, you can specify the values:

$vars = $this->requestAction('/articles/popular', [
  'environment' => ['CONTENT_TYPE' => 'application/json']
]);

Transmitting the session

By default actions dispatched with this method will use the standard session object. If you want a particular session instance to be used, you need to specify it.

$vars = $this->requestAction('/articles/popular', [
  'session' => new Session($someSessionConfig)
]);

Parameters

string|array $url: String or array-based url. Unlike other url arrays in CakePHP, this url will not automatically handle passed arguments in the $url parameter.
array $extra optional: if array includes the key "return" it sets the autoRender to true. Can also be used to submit GET/POST data, and passed arguments.

Returns

mixed

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.
