Methods
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Allows user code to hook into Object::extend prior to control being delegated to extensions. Each callback will be reset once called.
Allows user code to hook into Object::extend after control being delegated to extensions. Each callback will be reset once called.
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().
Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().
Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()
This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()
If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name
Get the value of a static property of a class, even in that property is declared protected (but not private), without any inheritance, merging or parent lookup if it doesn't exist on the given class.
Return TRUE if a class has a specified extension.
Add an extension to a specific class.
No description
Attemps to locate and call a method dynamically added to a class at runtime if a default cannot be located
Return the names of all the methods available on this object
Add methods from the ViewableData::$failover object, as well as wrapping any methods prefixed with an underscore into a ViewableData::cachedCall().
Add all the methods from an object property (which is an Extension) to this object.
Add all the methods from an object property (which is an Extension) to this object.
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)
Add an extra method using raw PHP code passed as a string
Check if this class is an instance of a specific class, or has that class as one of its parents
Calls a method if available on both this object and all applied Extensions, and then attempts to merge all results into an array
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
Get an extension instance attached to this object by name.
Returns TRUE if this object instance has a specific extension applied in $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.
Get all extension instances for this specific object instance.
Cache the results of an instance method in this object to a file, or if it is already cache return the cached results
Clears the cache for the given cacheToFile call
Loads a cache from the filesystem if a valid on is present and within the specified lifetime
Save a piece of cached data to the file system
Strip a file name of special characters so it is suitable for use as a cache file name
Converts a field spec into an object creator. For example: "Int" becomes "new Int($fieldName);" and "Varchar(50)" becomes "new Varchar($fieldName, 50);".
Convert a field schema (e.g. "Varchar(50)") into a casting object creator array that contains both a className and castingHelper constructor code. See castingObjectCreator for more information about the constructor.
Check if a field exists on this object or its failover.
Get the value of a property/field on this object. This will check if a method called get{$property} exists, then check if a field is available using ViewableData::getField(), then fall back on a failover object.
Set a property/field on this object. This will check for the existence of a method called set{$property}, then use the ViewableData::setField() method.
Set a failover object to attempt to get data from if it is not present on this object.
Check if a field exists on this object. This should be overloaded in child classes.
Get the value of a field on this object. This should be overloaded in child classes.
Set a field on this object. This should be overloaded in child classes.
Method to facilitate deprecation of underscore-prefixed methods automatically being cached.
Merge some arbitrary data in with this object. This method returns a ViewableData_Customised instance with references to both this and the new custom data.
Get the class a field on this object would be casted to, as well as the casting helper for casting a field to an object (see ViewableData::castingHelper() for information on casting helpers).
Return the "casting helper" (a piece of PHP code that when evaluated creates a casted value object) for a field on this object.
Get the class name a field on this object will be casted to
Return the string-format type for the given field.
Save the casting cache for this object (including data from any failovers) into a variable
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
Generate the cache name 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.
A simple wrapper around ViewableData::obj() that automatically caches the result so it can be used again without re-running the method.
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.
Get the string value of a field on this object that has been suitable escaped to be inserted directly into a template.
Return the value of the field without any escaping being applied.
Return the value of a field in an SQL-safe format.
Return the value of a field in a JavaScript-save format.
Return the value of a field escaped suitable to be inserted into an XML node attribute.
Get an array of XML-escaped values by field name
Return a single-item iterator so you can iterate over the fields of a single record.
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.
Return the directory if the current active theme (relative to the site root).
Get part of the current classes ancestry to be used as a CSS class.
Return debug information about this object that can be rendered into a template
Executes this controller, and return an SS_HTTPResponse object with the result.
Controller's default action handler. It will call the method named in $Action, if that method exists.

Checks if this request handler has a specific action, even if the current user cannot access it.
Return the class that defines the given action, so that we know where to check allowed_actions.
Check that the given action is allowed to be called from a URL.
Throws a HTTP error response encased in a SS_HTTPResponse_Exception, which is later caught in RequestHandler::handleAction() and returned to the user.

Typically the request is set through handleAction() or handleRequest(), but in some based we want to set it manually.
Returns a link to this controller. Overload with your own Link rules if they exist.
Returns the SS_HTTPResponse object that this controller is building up.
Sets the SS_HTTPResponse object that this controller is building up.
Return the object that is going to own a form that's being processed, and handle its execution.

Redirect back. Uses either the HTTP_REFERER or a manually set request-variable called "BackURL".
Joins two or more link segments together, putting a slash between them if necessary.
Called by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template
Uses the default SearchContext specified through DataObject::getDefaultSearchContext() to augument an existing query object (mostly a component query from DataObject) with search clauses.
Returns a dataformatter instance based on the request extension or mimetype. Falls back to self::$default_extension.
Converts either the given HTTP Body into an array (based on the DataFormatter instance), or returns the POST variables.
Gets a single DataObject by ID,
through a request like /api/v1/

Details
static Config_ForClass|null
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
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.
static SS_Object
create()
An implementation of the factory method, allows you to create an instance of a class
This method first for strong class overloads (singletons & DB interaction), then custom class overloads. If an overload is found, an instance of this is returned rather than the original class. To overload a class, use Object::useCustomClass()
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'); $list = SiteTree::get();
static SS_Object
singleton()
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static
create_from_string($classSpec, $firstArg = null)
Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().
Construction itself is done with Object::create(), so that Object::useCustomClass() calls are respected.
Object::create_from_string("Versioned('Stage','Live')") will return the result of
Versioned::create('Stage', 'Live);
It is designed for simple, clonable objects. The first time this method is called for a given string it is cached, and clones of that object are returned.
If you pass the $firstArg argument, this will be prepended to the constructor arguments. It's impossible to pass null as the firstArg argument.
Object::create_from_string("Varchar(50)", "MyField") will return the result of
Vachar::create('MyField', '50');
Arguments are always strings, although this is a quirk of the current implementation rather than something that can be relied upon.
static
parse_class_spec($classSpec)
Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().
Returns a 2-elemnent array, with classname and arguments
static SS_Object
strong_create()
Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()
static
useCustomClass(string $oldClass, string $newClass, bool $strong = false)
This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()
static string
getCustomClass(string $class)
If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name
static any
static_lookup($class, $name, null $default = null)
Get the value of a static property of a class, even in that property is declared protected (but not private), without any inheritance, merging or parent lookup if it doesn't exist on the given class.

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))
static
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.
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.

mixed
invokeWithExtensions(string $method, mixed $argument = null)
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 $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().
Extension
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(
array
getExtensionInstances()

Return the value of a field escaped suitable to be inserted into an XML node attribute.
array
getXMLValues($fields)
Get an array of XML-escaped values by field name
ArrayIterator
getIterator()
Return a single-item iterator so you can iterate over the fields of a single record.
This is useful so you can use a single record inside a <% control %> block in a template - and then use to access individual fields on this object.
ViewableData
Me()
When rendering some objects it is necessary to iterate over the object being rendered, to do this, you need access to itself.
string
ThemeDir(string $subtheme = false)
Return the directory if the current active theme (relative to the site root).
This method is useful for things such as accessing theme images from your template without hardcoding the theme
page - e.g. 
.
This method should only be used when a theme is currently active. However, it will fall over to the current project directory.
string
CSSClasses(string $stopAtClass = 'ViewableData')
Get part of the current classes ancestry to be used as a CSS class.
This method returns an escaped string of CSS classes representing the current classes ancestry until it hits a stop point - e.g. "Page DataObject ViewableData".
ViewableData_Debugger
Debug()
Return debug information about this object that can be rendered into a template
setDataModel($model)
Set the DataModel for this request.
SS_HTTPResponse|RequestHandler|string|array
handleRequest(SS_HTTPRequest $request, DataModel $model)
Executes this controller, and return an SS_HTTPResponse object with the result.
This method first does a few set-up activities:
- Push this controller ont to the controller stack - see Controller::curr() for information about this.
- Call init()
- Defer to RequestHandler->handleRequest() to determine which action should be executed
Note: $requestParams['executeForm'] support was removed, make the following change in your URLs: "/?executeForm=FooBar" -> "/FooBar" Also make sure "FooBar" is in the $allowed_actions of your controller class.
Note: You should rarely need to overload run() - 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->pushCurrent() and end the method with $this->popCurrent(). Failure to do this will create weird session errors.
protected
findAction($request)
No description
protected SS_HTTPResponse
handleAction($request, $action)

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.

SS_HTTPResponse
redirect($url, $code = 302)
Redirect to the given URL.
redirectBack()
Redirect back. Uses either the HTTP_REFERER or a manually set request-variable called "BackURL".
This variable is needed in scenarios where not HTTP-Referer is 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()).
string
redirectedTo()
Tests whether a redirection has been requested.
Session
getSession()
Get the Session object representing this Controller's session
setSession(Session $session)
Set the Session object.
static string
join_links()
Joins two or more link segments together, putting a slash between them if necessary.
Use this for building the results of Link() methods. If either of the links have query strings, then they will be combined and put at the end of the resulting url.
Caution: All parameters are expected to be URI-encoded already.
static array
get_template_global_variables()
Called by SSViewer to get a list of global variables to expose to the template, the static method to call on this class to get the value for those variables, and the class to use for casting the returned value for use in a template
If the method to call is not included for a particular template variable, a method named the same as the template variable will be called
If the casting class is not specified for a particular template variable, ViewableData::$default_cast is used
The first letter of the template variable is case-insensitive. However the method name is always case sensitive.
index()
This handler acts as the switchboard for the controller.
Since no $Action url-param is set, all requests are sent here.
protected string
getHandler(string $className, int $id, $relationName)
Handler for object read.
The data object will be returned in the following format:
Access is controlled by two variables:
- static $api_access must be set. This enables the API on a class by class basis
- $obj->canView() must return true. This lets you implement record-level security
protected SS_List
getSearchQuery(string $className, array $params = null, $sort = null, $limit = null, $existingQuery = null)
Uses the default SearchContext specified through DataObject::getDefaultSearchContext() to augument an existing query object (mostly a component query from DataObject) with search clauses.
protected DataFormatter
getDataFormatter(bool $includeAcceptHeader = false, $className = null)
Returns a dataformatter instance based on the request extension or mimetype. Falls back to self::$default_extension.

protected DataObject|string
updateDataObject(DataObject $obj, DataFormatter $formatter)
Converts either the given HTTP Body into an array (based on the DataFormatter instance), or returns the POST variables.
Automatically filters out certain critical fields that shouldn't be set by the client (e.g. ID).
protected DataList
getObjectQuery(string $className, int $id, array $params)
Gets a single DataObject by ID,
through a request like /api/v1/
