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" or "Translatable('Param')"

Return Value

bool

Flag if the extension was added

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.

Add support for removing extensions with parameters

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 $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

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 $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

List of results with nulls filtered out

array extend(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

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 $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

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

static Config_ForClass config()

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).

Return Value

Config_ForClass

HTTPResponse|RequestHandler|string|array handleRequest(HTTPRequest $request)

Executes this controller, and return an HTTPResponse object with the result.

This method defers to RequestHandler->handleRequest() to determine which action should be executed

Note: You should rarely need to overload handleRequest() - this kind of change is only really appropriate for things like nested controllers - ModelAsController} and {@link RootURLController are two examples here. If you want to make more orthodox functionality, it's better to overload init()} or {@link index().

Important: If you are going to overload handleRequest, make sure that you start the method with $this->beforeHandleRequest() and end the method with $this->afterHandleRequest()

Parameters

HTTPRequest $request

The object that is responsible for distributing URL parsing

Return Value

HTTPResponse|RequestHandler|string|array

protected array findAction(HTTPRequest $request)

Parameters

$request
$action

Return Value

HTTPResponse

array|null allowedActions(string $limitToClass = null)

Get a array of allowed actions defined on this controller, any parent classes or extensions.

Caution: Since 3.1, allowed_actions definitions only apply to methods on the controller they're defined on, so it is recommended to use the $class argument when invoking this method.

Parameters

string $limitToClass

Return Value

array|null

bool hasAction(string $action)

No description

Parameters

string $action

Return Value

bool

protected string definingClassForAction(string $action)

Return the class that defines the given action, so that we know where to check allowed_actions.

Overrides RequestHandler to also look at defined templates.

Parameters

string $action

Return Value

string

bool checkAccessAction(string $action)

Check that the given action is allowed to be called from a URL.

It will interrogate self::$allowed_actions to determine this.

Parameters

string $action

Return Value

bool

Exceptions

Exception

httpError(int $errorCode, string $errorMessage = null)

Throws a HTTP error response encased in a HTTPResponse_Exception, which is later caught in RequestHandler::handleAction() and returned to the user.

Parameters

int $errorCode
string $errorMessage

Plaintext error message

Exceptions

HTTPResponse_Exception

HTTPRequest getRequest()

Returns the HTTPRequest object that this controller is using.

Returns a placeholder NullHTTPRequest object unless handleAction()} or {@link handleRequest() have been called, which adds a reference to an actual HTTPRequest object.

Return Value

HTTPRequest

$this setRequest(HTTPRequest $request)

Typically the request is set through handleAction() or handleRequest(), but in some based we want to set it manually.

Parameters

HTTPRequest $request

Return Value

$this

You should implement a Link() function in your subclass of LeftAndMain, to point to the URL of that particular controller.

Parameters

string $action

Optional action

Return Value

string

HTTPResponse redirect(string $url, int $code = 302)

Overloaded redirection logic to trigger a fake redirect on ajax requests.

While this violates HTTP principles, its the only way to work around the fact that browsers handle HTTP redirects opaquely, no intervention via JS is possible. In isolation, that's not a problem - but combined with history.pushState() it means we would request the same redirection URL twice if we want to update the URL as well. See LeftAndMain.js for the required jQuery ajaxComplete handlers.

Parameters

string $url
int $code

Return Value

HTTPResponse

string getBackURL()

Safely get the value of the BackURL param, if provided via querystring / posted var

Return Value

string

string getReferer()

Get referer

Return Value

string

HTTPResponse redirectBack()

Redirect back. Uses either the HTTP-Referer or a manually set request-variable called "BackURL".

This variable is needed in scenarios where HTTP-Referer is not sent (e.g when calling a page by location.href in IE). If none of the two variables is available, it will redirect to the base URL (see Director::baseURL()).

Return Value

HTTPResponse

Form EditForm(HTTPRequest $request = null)

Retrieves an edit form, either for display, or to process submitted data.

Also used in the template rendered through Right() in the $EditForm placeholder.

This is a "pseudo-abstract" method, usually connected to a getEditForm() method in an entwine subclass. This method can accept a record identifier, selected either in custom logic, or through currentPageID(). The form usually construct itself from DataObject->getCMSFields() for the specific managed subclass defined in LeftAndMain::$tree_class.

Parameters

HTTPRequest $request

Passed if executing a HTTPRequest directly on the form. If empty, this is invoked as $EditForm in the template

Return Value

Form

Should return a form regardless wether a record has been found. Form might be readonly if the current user doesn't have the permission to edit the record.

Form getEditForm(int $id = null, FieldList $fields = null)

Calls SiteTree->getCMSFields() by default to determine the form fields to display.

Parameters

int $id
FieldList $fields

Return Value

Form

Form EmptyForm()

Returns a placeholder form, used by getEditForm() if no record is selected.

Our javascript logic always requires a form to be present in the CMS interface.

Return Value

Form

ModalController Modals()

Return Value

ModalController

string Tools()

Renders a panel containing tools which apply to all displayed "content" (mostly through EditForm()), for example a tree navigation or a filter panel.

Auto-detects applicable templates by naming convention: "_Tools.ss", and takes the most specific template (see getTemplatesWithSuffix()). To explicitly disable the panel in the subclass, simply create a more specific, empty template.

Return Value

string HTML

string EditFormTools()

Renders a panel containing tools which apply to the currently displayed edit form.

The main difference to Tools() is that the panel is displayed within the element structure of the form panel (rendered through EditForm). This means the panel will be loaded alongside new forms, and refreshed upon save, which can mean a performance hit, depending on how complex your panel logic gets. Any form fields contained in the returned markup will also be submitted with the main form, which might be desired depending on the implementation details.

Return Value

string HTML

Return Value

int

setCurrentPageID(int $id)

Forces the current page to be set in session, which can be retrieved later through currentPageID().

Keep in mind that setting an ID through GET/POST or as a URL parameter will overrule this value.

Parameters

DataObject currentPage()

Uses getRecord()} and {@link currentPageID() to get the currently selected record.

Return Value

DataObject

bool isCurrentPage(DataObject $record)

Compares a given record to the currently selected one (if any).
