View Helpers

Navigation Proxy
The navigation() helper is a proxy helper that relays calls to other
navigational helpers. It can be considered an entry point to all
navigation-related view tasks.
The Navigation helper finds other helpers that implement
Zend\View\Helper\Navigation\HelperInterface, which means custom view helpers
can also be proxied. This would, however, require that the custom helper path
is added to the view.
When proxying to other helpers, the Navigation helper can inject its
container, ACL and optionally role, and a translator. This means that you won't
have to explicitly set all three in all navigational helpers, nor resort to
injecting by means of static methods.
Methods
| Method signature | Description |
|---|---|
findHelper(string $helper, bool $strict = true) : Navigation\HelperInterface |
Finds the given helper, verifies that it is a navigational helper, and injects the current container, ACL and role instances, and translator, if present. If $strict is true, the method will raise an exception when unable to find a valid helper. |
getInjectContainer() : bool |
Retrieve the flag indicating whether or not to inject the current container into proxied helpers; default is true. |
setInjectContainer(bool $flag) : self |
Set the flag indicating whether or not to inject the current container into proxied helpers. |
getInjectAcl() : bool |
Retrieve the flag indicating whether or not to inject ACL and role instances into proxied helpers; default is true. |
setInjectAcl(bool $flag) : self |
Set the flag indicating whether or not to inject ACL and role instances into proxied helpers. |
getInjectTranslator() : bool |
Retrieve the flag indicating whether or not to inject the current translator instance into proxied helpers; default is true. |
setInjectTranslator(bool $flag) : self |
Set the flag indicating whether or not to inject the current translator instance into proxied helpers. |
getDefaultProxy() : string |
Retrieve the default proxy helper to delegate to when rendering; defaults to menu. |
setDefaultProxy(string $helper) : self |
Set the default proxy helper to delegate to when rendering. |
render(AbstractContainer = null) |
Proxies to the render method of the default proxy. |
