interface UrlGeneratorInterface implements RequestContextAwareInterface
UrlGeneratorInterface is the interface that all URL generator classes must implement.
The constants in this interface define the different types of resource references that are declared in RFC 3986: http://tools.ietf.org/html/rfc3986 We are using the term "URL" instead of "URI" as this is more common in web applications and we do not need to distinguish them as the difference is mostly semantical and less technical. Generating URIs, i.e. representation-independent resource identifiers, is also possible.
Constants
| ABSOLUTE_URL | Generates an absolute URL, e.g. "http://example.com/dir/file". |
| ABSOLUTE_PATH | Generates an absolute path, e.g. "/dir/file". |
| RELATIVE_PATH | Generates a relative path based on the current request path, e.g. ". ./parent-file". |
| NETWORK_PATH | Generates a network path, e.g. "//example.com/dir/file". Such reference reuses the current scheme but specifies the host. |
Methods
| setContext(RequestContext $context) Sets the request context. | from RequestContextAwareInterface | |
| RequestContext | getContext() Gets the request context. | from RequestContextAwareInterface |
| string | generate(string $name, mixed $parameters = array(), int $referenceType = self::ABSOLUTE_PATH) Generates a URL or path for a specific route based on the given parameters. |
Details
setContext(RequestContext $context)
Sets the request context.
RequestContext getContext()
Gets the request context.
string generate(string $name, mixed $parameters = array(), int $referenceType = self::ABSOLUTE_PATH)
Generates a URL or path for a specific route based on the given parameters.
Parameters that reference placeholders in the route pattern will substitute them in the path or host. Extra params are added as query string to the URL.
When the passed reference type cannot be generated for the route because it requires a different host or scheme than the current one, the method will return a more comprehensive reference that includes the required params. For example, when you call this method with $referenceType = ABSOLUTEPATH but the route requires the https scheme whereas the current scheme is http, it will instead return an ABSOLUTEURL with the https scheme and the current host. This makes sure the generated URL matches the route in any case.
If there is no route with the given name, the generator must throw the RouteNotFoundException.
