Details

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

array getMultipartSchema(array|string $schemaParts, string $schemaID, Form $form = null, ValidationResult $result = null)

Returns a representation of the provided Form as structured data, based on the request data.

Parameters

array|string $schemaParts

Array or list of requested parts.

string $schemaID

ID for this schema. Required.

Form $form

Required for 'state' or 'schema' response

ValidationResult $result

Required for 'error' response

Return Value

array

array getSchema(Form $form)

Gets the schema for this form as a nested array.

Parameters

Form $form

Return Value

array

array getState(Form $form)

Gets the current state of this form as a nested array.

Parameters

Form $form

Return Value

array

array getErrors(ValidationResult $result)

No description

Parameters

ValidationResult $result

Return Value

array

List of errors

protected array getSchemaForMessage(array $message)

Return form schema for encoded validation message

Parameters
