Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

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.

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

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();

Return Value

SS_Object

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).

Return Value

SS_Object

The singleton instance

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.

Parameters

$classSpec
$firstArg

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

Parameters

$classSpec

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()

Return Value

SS_Object

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()

Parameters

string $oldClass

the class to replace

string $newClass

the class to replace it with

bool $strong

allows you to enforce a certain class replacement under all circumstances. This is used in singletons and DB interaction classes

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

Parameters

string $class

the class to check

Return Value

string

static 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

if 1 argument supplied, the class name of the extension to check for; if 2 supplied, the class name to test

string $requiredExtension

used only if 2 arguments supplied

bool $strict

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

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()).

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')"

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

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.

Add support for removing extensions with parameters

Parameters

string $extension

Classname of an Extension subclass, without parameters

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

This method should be overriden 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

Return Value

bool

string parentClass()

integrate inheritance rules

Parameters

string $method

the method name to call

mixed $argument

a single argument to pass

Return Value

mixed

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 getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension

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

array 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).

setDataModel($model)

Set the DataModel for this request.

Parameters

$model

SS_HTTPResponse|RequestHandler|string|array handleRequest(SS_HTTPRequest $request, DataModel $model)

Handles URL requests.

  • ViewableData::handleRequest() iterates through each rule in self::$url_handlers.
    • If the rule matches, the named method will be called.
    • If there is still more URL to be processed, then handleRequest() is called on the object that that method returns.

Once all of the URL has been processed, the final result is returned. However, if the final result is an array, this array is interpreted as being additional template data to customise the 2nd to last result with, rather than an object in its own right. This is most frequently used when a Controller's action will return an array of data with which to customise the controller.

Parameters

SS_HTTPRequest $request

The SS_HTTPRequest object that is reponsible for distributing URL parsing

DataModel $model

Return Value

SS_HTTPResponse|RequestHandler|string|array

bool validate()

Processing that occurs before a form is executed.

Return Value

bool

Form loadDataFrom(array|DataObject $data, int $mergeStrategy = 0, array $fieldList = null)

Load data from the given DataObject or array.

It will call $object->MyField to get the value of MyField. If you passed an array, it will call $object[MyField]. Doesn't save into dataless FormFields (DatalessField), as determined by FieldList->dataFields().

By default, if a field isn't set (as determined by isset()), its value will not be saved to the field, retaining potential existing values.

Passed data should not be escaped, and is saved to the FormField instances unescaped. Escaping happens automatically on saving the data through saveInto().

Escaping happens automatically on saving the data through saveInto().

Parameters

array|DataObject $data
int $mergeStrategy

For every field, $data is interrogated whether it contains a relevant property/key, and what that property/key's value is.

By default, if $data} does contain a property/key, the fields value is always replaced by {@link $data's value, even if that value is null/false/etc. Fields which don't match any property/key in $data are "left alone", meaning they retain any previous value.

You can pass a bitmask here to change this behaviour.

Passing CLEAR_MISSING means that any fields that don't match any property/key in $data are cleared.

Passing IGNORE_FALSEISH means that any false-ish value in $data won't replace a field's value.

For backwards compatibility reasons, this parameter can also be set to === true, which is the same as passing CLEAR_MISSING

array $fieldList

An optional list of fields to process. This can be useful when you have a form that has some fields that save to one object, and some that save to another.

Return Value

Form

saveInto(DataObjectInterface $dataObject, FieldList $fieldList = null)

FieldList $fieldList

An optional list of fields to process. This can be useful when you have a form that has some fields that save to one object, and some that save to another.
