mixed

Exceptions

BadMethodCallException

protected defineMethods()

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

protected registerExtraMethodCallback(string $name, callable $callback)

Register an callback to invoke that defines extra methods

Parameters

string $name
callable $callback

bool hasMethod(string $method)

Determines if a custom method with this name is defined.

Parameters

$method

Return Value

bool

protected array getExtraMethodConfig(string $method)

the property name

string|int $index

an index to use if the property is an array

protected addWrapperMethod(string $method, string $wrap)

Add a wrapper method - a method which points to another method with a different name. For example, Thumbnail(x) can be wrapped to generateThumbnail(x)

Parameters

string $method

the method name to wrap

string $wrap

the method name to wrap to

protected addCallbackMethod(string $method, callable $callback)

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

Adds any methods from Extension instances attached to this object.

All these methods can then be called directly on the instance (transparently mapped through __call()}), or called explicitly through {@link extend().

static bool add_extension(string $classOrExtension, string $extension = null)

Add an extension to a specific class.

The preferred method for adding extensions is through YAML config, since it avoids autoloading the class, and is easier to override in more specific configurations.

As an alternative, extensions can be added to a specific class directly in the Object::$extensions array. See SiteTree::$extensions for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through singleton()).

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of Object

string $extension

Subclass of Extension with optional parameters as a string, e.g. "Versioned"

Return Value

bool

Flag if the extension was added

See also

http://doc.silverstripe.org/framework/en/trunk/reference/dataextension

static remove_extension(string $extension)

Remove an extension from a class.

Note: This will not remove extensions from parent classes, and must be called directly on the class assigned the extension.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Parameters

string $extension

class name of an Extension subclass, without parameters

static array get_extensions(string $class = null, bool $includeArgumentString = false)

No description

Parameters

string $class

If omitted, will get extensions for the current class

bool $includeArgumentString

Include the argument string in the return array, FALSE would return array("Versioned"), TRUE returns array("Versioned('Stage','Live')").

Return Value

array

Numeric array of either DataExtension class names, or eval'ed class name strings with constructor arguments.

static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

Parameters

string $class

Name of class. If left null will return for the current class

Return Value

array|null

static bool has_extension(string $classOrExtension, string $requiredExtension = null, bool $strict = false)

Return TRUE if a class has a specified extension.

This supports backwards-compatible format (static Object::has_extension($requiredExtension)) and new format ($object->has_extension($class, $requiredExtension))

Parameters

string $classOrExtension

Class to check extension for, or the extension name to check if the second argument is null.

string $requiredExtension

If the first argument is the parent class, this is the extension to check. If left null, the first parameter will be treated as the extension.

bool $strict

if the extension has to match the required extension and not be a subclass

Return Value

bool

Flag if the extension exists

array invokeWithExtensions(string $method, mixed ...$arguments)

Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array

Parameters

string $method

the method name to call

mixed ...$arguments

List of arguments

Return Value

array

List of results with nulls filtered out

array extend(string $method, mixed ...$arguments)

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Parameters

string $method

the name of the method to call on each extension

mixed ...$arguments

Return Value

array

Extension|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

bool hasExtension(string $extension)

Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Parameters

string $extension

Classname of an Extension subclass without parameters

Return Value

bool

Extension[] getExtensionInstances()

Get all extension instances for this specific object instance.

See get_extensions() to get all applied extension classes for this class (not the instance).

This method also provides lazy-population of the extension_instances property.

Return Value

Extension[]

Map of DataExtension instances, keyed by classname.

static Injectable create(mixed ...$args)

An implementation of the factory method, allows you to create an instance of a class

This method will defer class substitution to the Injector API, which can be customised via the Config API to declare substitution classes.

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create(SiteTree::class); $list = SiteTree::get();

Parameters

mixed ...$args

Return Value

Injectable

static Injectable singleton(string $class = null)

Creates a class instance by the "singleton" design pattern.

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Parameters

string $class

Optional classname to create, if the called class should not be used

Return Value

Injectable

The singleton instance

Result of callback

HTTPResponse handleRequest(HTTPRequest $request)

Process the given URL, creating the appropriate controller and executing it.

Request processing is handled as follows:

  • Director::handleRequest($request) checks each of the Director rules and identifies a controller to handle this request.
  • Controller::handleRequest($request) is then called. This will find a rule to handle the URL, and call the rule handling method.
  • RequestHandler::handleRequest($request) is recursively called whenever a rule handling method returns a RequestHandler object.

In addition to request processing, Director will manage the session, and perform the output of the actual response to the browser.

Parameters

HTTPRequest $request

Return Value

HTTPResponse

Exceptions

HTTPResponse_Exception

static SiteTree|Controller get_current_page()

Return the SiteTree object that is currently being viewed. If there is no SiteTree object to return, then this will return the current controller.

Checks if a given URL is absolute (e.g. starts with 'http://' etc.). URLs beginning with "//" are treated as absolute, as browsers take this to mean the same protocol as currently being used.

Useful to check before redirecting based on a URL from user submissions through $_GET or $_POST, and avoid phishing attacks by redirecting to an attackers server.

Note: Can't solely rely on PHP's parse_url() , since it is not intended to work with relative URLs or for security purposes. filter_var($url, FILTER_VALIDATE_URL) has similar problems.

Parameters

string $url

Return Value

bool

static bool is_relative_url(string $url)

Checks if a given URL is relative (or root relative) by checking is_absolute_url().

Parameters

string $url

Return Value

bool

static bool is_site_url(string $url)

Checks if the given URL is belonging to this "site" (not an external link). That's the case if the URL is relative, as defined by is_relative_url(), or if the host matches protocolAndHost().

Useful to check before redirecting based on a URL from user submissions through $_GET or $_POST, and avoid phishing attacks by redirecting to an attackers server.

Provides an extension point to allow extra checks on the URL to allow some external URLs, e.g. links on secondary domains that point to the same CMS, or subsite domains.

Parameters

string $url

Return Value

bool

static string getAbsFile(string $file)

Given a filesystem reference relative to the site root, return the full file-system path.

Parameters

string $file

Return Value

string

static bool fileExists($file)

Returns true if the given file exists. Filename should be relative to the site root.

Parameters

$file

Return Value

bool

static string absoluteBaseURL()

Returns the Absolute URL of the site root.

Return Value

string

static string absoluteBaseURLWithAuth(HTTPRequest $request = null)

Returns the Absolute URL of the site root, embedding the current basic-auth credentials into the URL.

Parameters

HTTPRequest $request

Return Value

string

static protected force_redirect(string $destURL)

Skip any further processing and immediately respond with a redirect to the passed URL.

Parameters

string $destURL

Exceptions

HTTPResponse_Exception

static forceSSL(array $patterns = null, string $secureDomain = null, HTTPRequest $request = null)

Force the site to run on SSL.

To use, call from _config.php. For example:

if (Director::isLive()) Director::forceSSL();

If you don't want your entire site to be on SSL, you can pass an array of PCRE regular expression patterns for matching relative URLs. For example:

if (Director::isLive()) Director::forceSSL(array('/^admin/', '/^Security/'));

If you want certain parts of your site protected under a different domain, you can specify the domain as an argument:

if (Director::isLive()) Director::forceSSL(array('/^admin/', '/^Security/'), 'secure.mysite.com');

Note that the session data will be lost when moving from HTTP to HTTPS. It is your responsibility to ensure that this won't cause usability problems.

CAUTION: This does not respect the site environment mode. You should check this as per the above examples using Director::isLive() or Director::isTest() for example.

Parameters

array $patterns

Array of regex patterns to match URLs that should be HTTPS.

string $secureDomain

Secure domain to redirect to. Defaults to the current domain. Can include port number.

HTTPRequest $request

Request object to check

static forceWWW(HTTPRequest $request = null)

Force a redirect to a domain starting with "www."

Parameters

HTTPRequest $request

static bool is_ajax(HTTPRequest $request = null)

Checks if the current HTTP-Request is an "Ajax-Request" by checking for a custom header set by jQuery or whether a manually set request-parameter 'ajax' is present.

Note that if you plan to use this to alter your HTTP response on a cached page, you should add X-Requested-With to the Vary header.

Parameters

HTTPRequest $request

Return Value

bool

static bool is_cli()

Returns true if this script is being run from the command line rather than the web server.

Return Value

bool

static string get_environment_type()

Can also be checked with Director::isDev()}, {@link Director::isTest(), and Director::isLive().

Return Value

string

static bool isLive()

This function will return true if the site is in a live environment. For information about environment types, see Director::set_environment_type().

Return Value

bool

static bool isDev()

This function will return true if the site is in a development environment. For information about environment types, see Director::set_environment_type().

Return Value

bool

static bool isTest()

This function will return true if the site is in a test environment. For information about environment types, see Director::set_environment_type().

Return Value

bool

static array get_template_global_variables()

Returns an array of strings of the method names of methods on the call that should be exposed as global variables in the templates.

Return Value

array

Returns an array of items. Each key => value pair is one of three forms:

  • template name (no key)
  • template name => method name
  • template name => [], where the array can contain these key => value pairs
    • "method" => method name
    • "casting" => casting class to use (i.e., Varchar, HTMLFragment, etc)

static protected HTTPRequest currentRequest(HTTPRequest $request = null)

Helper to validate or check the current request object

Parameters

HTTPRequest $request

Return Value

HTTPRequest

Request object if one is both current and valid
