Method Details

__call()

Magic overload: Proxy calls to the navigation container

Parameter Name	Type	Description
$method	string	method
$arguments	array	rguments

Returns: mixed

__invoke()

Helper entry point.

Parameter Name	Type	Description
$container	string|\AbstractContainer	container

Returns: \Breadcrumbs

__toString()

Magic overload: Proxy to {@link render()}.

This method will trigger an E_USER_ERROR if rendering the helper causes an exception to be thrown.

Implements {@link HelperInterface::__toString()}.

Returns: string

accept()

Determines whether a page should be accepted when iterating

Default listener may be 'overridden' by attaching listener to 'isAllowed' method. Listener must be 'short circuited' if overriding default ACL listener.

Rules:

• If a page is not visible it is not accepted, unless RenderInvisible has been set to true
• If $useAcl is true (default is true):
  • Page is accepted if listener returns true, otherwise false
• If page is accepted and $recursive is true, the page will not be accepted if it is the descendant of a non-accepted page

Parameter Name	Type	Description
$page	\AbstractPage	page
$recursive	bool	[optional]

Returns: bool Whether page should be accepted

findActive()

Finds the deepest active page in the given container

Parameter Name	Type	Description
$container	\Navigation\AbstractContainer	container
$minDepth	int|null	[optional]
$maxDepth	int|null	[optional]

Returns: array an associative array with the values 'depth' and 'page', or an empty array if not found

getAcl()

Returns ACL or null if it isn't set using {@link setAcl()} or {@link setDefaultAcl()}

Implements {@link HelperInterface::getAcl()}.

Returns: \Acl\AclInterface|null ACL object or null

getContainer()

Returns the navigation container helper operates on by default

Implements {@link HelperInterface::getContainer()}.

If no container is set, a new container will be instantiated and stored in the helper.

Returns: \Navigation\AbstractContainer navigation container

getEventManager()

Get the event manager, if present.

Internally, the helper will lazy-load an EM instance the first time it requires one, but ideally it should be injected during instantiation.

Returns: null|\EventManagerInterface

getIndent()

Returns indentation

Returns: string

getLinkLast()

Returns whether last page in breadcrumbs should be hyperlinked.

Returns: bool

getMaxDepth()

Returns maximum depth a page can have to be included when rendering

Returns: int|null

getMinDepth()

Returns minimum depth a page must have to be included when rendering

Returns: int|null

getPartial()

Returns partial view script to use for rendering menu.

Returns: string|array|null

getRenderInvisible()

Return renderInvisible flag

Returns: bool

getRole()

Returns ACL role to use when iterating pages, or null if it isn't set using {@link setRole()} or {@link setDefaultRole()}

Implements {@link HelperInterface::getRole()}.

Returns: string|\Acl\Role\RoleInterface|null

getSeparator()

Returns breadcrumb separator.

Returns: string breadcrumb separator

getServiceLocator()

Get the service locator.

Used internally to pull named navigation containers to render.

Returns: \ContainerInterface

getUseAcl()

Returns whether ACL should be used

Implements {@link HelperInterface::getUseAcl()}.

Returns: bool

hasAcl()

Checks if the helper has an ACL instance

Implements {@link HelperInterface::hasAcl()}.

Returns: bool

hasContainer()

Checks if the helper has a container

Implements {@link HelperInterface::hasContainer()}.

Returns: bool

hasRole()

Checks if the helper has an ACL role

Implements {@link HelperInterface::hasRole()}.

Returns: bool

htmlify()

Returns an HTML string containing an 'a' element for the given page

Parameter Name	Type	Description
$page	\AbstractPage	page

Returns: string HTML string (<a href="…">Label</a>)

render()

Renders helper.

Implements {@link HelperInterface::render()}.

Parameter Name	Type	Description
$container	\AbstractContainer	[optional]

Returns: string

renderPartial()

Renders the given $container by invoking the partial view helper.

The container will simply be passed on as a model to the view script as-is, and will be available in the partial script as 'container', e.g. echo 'Number of pages: ', count($this->container);.

Parameter Name	Type	Description
$container	null|\AbstractContainer	[optional]
$partial	null|string|array	[optional]

Returns: string

renderPartialWithParams()

Renders the given $container by invoking the partial view helper with the given parameters as the model.

The container will simply be passed on as a model to the view script as-is, and will be available in the partial script as 'container', e.g. echo 'Number of pages: ', count($this->container);.

Any parameters provided will be passed to the partial via the view model.

Parameter Name	Type	Description
$container	null|\AbstractContainer	[optional]
$partial	null|string|array	[optional]
