Get an extension instance attached to this object by name.
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.

Get a cached value from the field cache for a field
Store a value in the field cache for a field
Get the value of a field on this object, automatically inserting the value into any available casting objects that have been specified.

Get the absolute URL for this controller, including protocol and host.
Overloaded redirection logic to trigger a fake redirect on ajax requests.
Safely get the value of the BackURL param, if provided via querystring / posted var
Redirect back. Uses either the HTTP-Referer or a manually set request-variable called "BackURL".
Convert an array of data to JSON and wrap it in an HTML tag as pjax is used and jQuery will parse this as an element on the client side in LeftAndMain.js handleAjaxResponse() The attribute type="application/json" denotes this is a data block and won't be processed by a browser https://html.spec.whatwg.org/#the-script-element
Initialisation function that is run before any action on the controller is called.

Render the current controller with the templates determined by getViewer().
Returns true if the member is allowed to do the given action. Defaults to the currently logged in user.
Pushes this controller onto the stack of current controllers. This means that any redirection, session setting, or other things that rely on Controller::curr() will now write to this controller object.
Tests whether a redirection has been requested. If redirect() has been called, it will return the URL redirected to. Otherwise, it will return null.
Joins two or more link segments together, putting a slash between them if necessary. Use this for building the results of Link() methods. If either of the links have query strings, then they will be combined and put at the end of the resulting url.

Details
mixed
__call(string $method, array $arguments)
Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located
You can add extra methods to a class using Extensions}, {@link Object::createMethod() or Object::addWrapperMethod()
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
bool
hasMethod(string $method)
Return TRUE if a method exists on this object
This should be used rather than PHP's inbuild method_exists() as it takes into account methods added via extensions
protected bool
hasCustomMethod($method)
Determines if a custom method with this name is defined.
protected array
getExtraMethodConfig(string $method)
Get meta-data details on a named method
array
allMethodNames(bool $custom = false)
Return the names of all the methods available on this object
static protected array
findBuiltInMethods(string|object $class = null)
Get all public built in methods for this class
protected array
findMethodsFrom(object $object)
Find all methods on the given object.
protected
addMethodsFrom(string $property, string|int $index = null)
Add all the methods from an object property.
protected
removeMethodsFrom(string $property, string|int $index = null)
Add all the methods from an object property (which is an Extension) to this object.
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)
protected
addCallbackMethod(string $method, callable $callback)
Add callback as a method.
protected
beforeExtending(string $method, callable $callback)
Allows user code to hook into Object::extend prior to control being delegated to extensions. Each callback will be reset once called.
protected
afterExtending(string $method, callable $callback)
Allows user code to hook into Object::extend after control being delegated to extensions. Each callback will be reset once called.
protected
defineExtensionMethods()
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()).
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.
static array
get_extensions(string $class = null, bool $includeArgumentString = false)
No description
static array|null
get_extra_config_sources(string $class = null)
Get extra config sources for this class
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))
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
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().
Extension|null
getExtensionInstance(string $extension)
Get an extension instance attached to this object by name.
bool
hasExtension(string $extension)
Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.
Caution: Don't use singleton(
Extension[]
getExtensionInstances()
Get all extension instances for this specific object instance.
See get_extensions() to get all applied extension classes for this class (not the instance).
This method also provides lazy-population of the extension_instances property.
static Injectable
create(mixed ...$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();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static Config_ForClass
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
uninherited(string $name)
Gets the uninherited value for the given config option
__construct()
No description
bool
__isset(string $property)
Check if a field exists on this object or its failover.
Note that, unlike the core isset() implementation, this will return true if the property is defined and set to null.
mixed
__get(string $property)
Get the value of a property/field on this object. This will check if a method called get{$property} exists, then check if a field is available using ModelData::getField(), then fall back on a failover object.
void
__set(string $property, mixed $value)
Set a property/field on this object. This will check for the existence of a method called set{$property}, then use the ModelData::setField() method.
void
setFailover(ModelData $failover)

ModelData
customise(ModelData $data)
Merge some arbitrary data in with this object. This method returns a ModelDataCustomised instance with references to both this and the new custom data.
Note that any fields you specify will take precedence over the fields on this object.
bool
exists()
Return true if this object "exists" i.e. has a sensible value
This method should be overridden in subclasses to provide more context about the classes state. For example, a DataObject class could return false when it is deleted from the database
string
__toString()
Return the class name (though subclasses may return something else)
string
forTemplate()
Return the HTML markup that represents this model when it is directly injected into a template (e.g. using $Me).
By default this attempts to render the model using templates based on the class hierarchy.

getCustomisedObj()
No description
setCustomisedObj(ModelData $object)
No description
string|null
castingHelper(string $field)
Return the "casting helper" (an injectable service name) for a field on this object. This helper will be a subclass of DBField.
DBHTMLText
renderWith(string|array|SSViewer $template, ModelData|array $customFields = [])
Render this object into the template, and get the result as a string. You can pass one of the following as the $template parameter:
- a template name (e.g. Page)
- an array of possible template names - the first valid one will be used
- an SSViewer instance
mixed

Get the value of a field on this object, automatically inserting the value into any available casting objects that have been specified.
bool
hasValue(string $field, array $arguments = [], bool $cache = true)
Checks if a given method/field has a valid value. If the result is an object, this will return the result of the exists method, otherwise will check if the result is not just an empty paragraph tag.
array
getStatusFlags(bool $cached = true)
Flags provides the user with additional data about the current page status.
Mostly this is used for versioning, but can be used for other purposes (e.g. localisation). Each page can have more than one status flag.
Returns an associative array of a unique key to a (localized) title for the flag. The unique key can be reused as a CSS class.
Example (simple): "deletedonlive" => "Deleted"
Example (with optional title attribute): "deletedonlive" => ['text' => "Deleted", 'title' => 'This page has been deleted']
string
getStatusFlagMarkup(string $additionalCssClass = '')
Get the HTML markup for rendering status flags for this model.
array
getViewerTemplates(string $suffix = '')
Find appropriate templates for SSViewer to use to render this object
ModelData
Me()
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.
string
CSSClasses(string $stopAtClass = ModelData::class)
Get part of the current classes ancestry to be used as a CSS class.
This method returns an escaped string of CSS classes representing the current classes ancestry until it hits a stop point - e.g. "Page DataObject ModelData".
ModelData|string
Debug()
Return debug information about this object that can be rendered into a template
ModelData
flushCache()
Clears record-specific cached data.
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()
protected array
findAction(HTTPRequest $request)
No description
protected string
addBackURLParam(string $link)
No description
protected HTTPResponse
handleAction($request, $action)
Controller's default action handler. It will call the method named in "$Action", if that method exists. If "$Action" isn't given, it will use "index" as a default.
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.
bool
hasAction(string $action)
No description
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.
bool
checkAccessAction(string $action)
Check that the given action is allowed to be called from a URL.
It will interrogate RequestHandler::$allowed_actions to determine this.
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.
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.
RequestHandler
setRequest(HTTPRequest $request)
Typically the request is set through handleAction() or handleRequest(), but in some based we want to set it manually.
?string
Link(string $action = null)
Returns a link to this controller.
Returns null if no link could be generated.
Overload with your own Link rules if they exist.
?string
AbsoluteLink(string $action = '')
Get the absolute URL for this controller, including protocol and host.
Returns null if no link could be generated.
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.
string
getBackURL()
Safely get the value of the BackURL param, if provided via querystring / posted var
string
getReferer()

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()).
protected string
prepareDataForPjax(array $data)
Convert an array of data to JSON and wrap it in an HTML tag as pjax is used and jQuery will parse this as an element on the client side in LeftAndMain.js handleAjaxResponse() The attribute type="application/json" denotes this is a data block and won't be processed by a browser https://html.spec.whatwg.org/#the-script-element
