set(string $var, mixed $value)

Views have a set() method that is analogous to the set() found in Controller objects. It allows you to add variables to the viewVars. Using set() from your view file will add the variables to the layout and elements that will be rendered later. See Controller::set() for more information on using set().

In your view file you can do

	$this->set('activeMenuButton', 'posts');

1. $this->set('activeMenuButton', 'posts');

Then in your layout the $activeMenuButton variable will be available and contain the value 'posts'.

getVar(string $var)

Gets the value of the viewVar with the name $var

getVars()

Gets a list of all the available view variables in the current rendering scope. Returns an array of variable names.

error(int $code, string $name, string $message)

Displays an error page to the user. Uses layouts/error.ctp to render the page.

	$this->error(404, 'Not found', 'This page was not found, sorry');

1. $this->error(404, 'Not found', 'This page was not found, sorry');

This will render an error page with the title and messages specified. Its important to note that script execution is not stopped by View::error() So you will have to stop code execution yourself if you want to halt the script.

element(string $elementPath, array $data, bool $loadHelpers)

Renders an element or view partial. See the section on View Elements for more information and examples.

uuid(string $object, mixed $url)

Generates a unique non-random DOM ID for an object, based on the object type and url. This method is often used by helpers that need to generate unique DOM ID's for elements such as the AjaxHelper.

	$uuid = $this->uuid('form', array('controller' => 'posts', 'action' => 'index'));
	//$uuid contains 'form0425fe3bad'

1. $uuid = $this->uuid('form', array('controller' => 'posts', 'action' => 'index'));
2. //$uuid contains 'form0425fe3bad'

addScript(string $name, string $content)

Adds content to the internal scripts buffer. This buffer is made available in the layout as $scripts_for_layout. This method is helpful when creating helpers that need to add javascript or css directly to the layout. Keep in mind that scripts added from the layout, or elements in the layout will not be added to $scripts_for_layout. This method is most often used from inside helpers, like the Javascript and Html Helpers.
