Constants

CHANGE_NONE

Represents a field that hasn't changed (before === after, thus before == after)

CHANGE_STRICT

Represents a field that has changed type, although not the loosely defined value.

(before !== after && before == after) E.g. change 1 to true or "true" to true, but not true to 0. Value changes are by nature also considered strict changes.

CHANGE_VALUE

Represents a field that has changed the loosely defined value (before != after, thus, before !== after)) E.g. change false to true, but not false to 0

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

the class that would be created if you called Object::create() with the class

static any static_lookup($class, $name, null $default = null)

  • The class to get the static from
$name
  • The property to get from the class
null $default
  • The value to return if property doesn't exist on class

Return Value

any
  • The value of the static property $name on class $class, or $default if that property is not defined

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')"

See also

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)

No description

Parameters

string $class
bool $includeArgumentString

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

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

deprecated 3.2 Use the "DataObject.validation_enabled" config setting instead

Set whether DataObjects should be validated before they are written.

Caution: Validation can contain safeguards against invalid/malicious data, and check permission levels (e.g. on Group). Therefore it is recommended to only disable validation for very specific use cases.

Parameters

$enable bool

Parameters

string $class

Return Value

array

Map of fieldname to specification, similiar to DataObject::$db.

You'll need to call this to get the memory of an object that has components or extensions freed.

DataObject duplicate($doWrite = true)

Create a duplicate of this node.

Note: now also duplicates relations.

Parameters

$doWrite

Perform a write() operation before returning the object. If this is true, it will create the duplicate in the database.

getClassName()

No description

DataObject setClassName(string $className)

Set the ClassName attribute. $class is also updated.

Warning: This will produce an inconsistent record, as the object instance will not automatically switch to the new subclass. Please use newClassInstance() for this purpose, or destroy and reinstanciate the record.

Parameters

string $className

The new ClassName attribute (a subclass of DataObject)

Return Value

DataObject $this

DataObject newClassInstance(string $newClassName)

Create a new instance of a different class from this object's record.

This is useful when dynamically changing the type of an instance. Specifically, it ensures that the instance of the class is a match for the className of the record. Don't set the DataObject->class} or {@link DataObject->ClassName property manually before calling this method, as it will confuse change detection.

If the new class is different to the original class, defaults are populated again because this will only occur automatically on instantiation of a DataObject if there is no record, or the record has no ID. In this case, we do have an ID but we still need to repopulate the defaults.

Parameters

string $newClassName

The name of the new class

Return Value

DataObject

The new instance of the new class, The exact type will be of the class name provided.

bool isEmpty()

Returns TRUE if all values (other than "ID") are considered empty (by weak boolean comparison).

Only checks for fields listed in custom_database_fields()

Use DBField->hasValue()

Return Value

bool

string

User friendly translated singular name of this DataObject

string plural_name()

Get the user friendly plural name of this DataObject If the name is not defined (by renaming $plural_name in the subclass), this returns a pluralised version of the class name.

Return Value

string

User friendly plural name of this DataObject

string i18n_plural_name()

Get the translated user friendly plural name of this DataObject Same as plural_name but runs it through the translation function Translation string is in the form: $this->class.PLURALNAME Example: Page.PLURALNAME

Associated database record

array toMap()

Convert this object to a map.

Return Value

array

The data as a map.

array getQueriedDatabaseFields()

Return all currently fetched database fields.

Return Value

array

The data as a map.

DataObject update(array $data)

Update a number of fields on this object, given a map of the desired changes.

The field names can be simple names, or you can use a dot syntax to access $has_one relations. For example, array("Author.FirstName" => "Jim") will set $this->Author()->FirstName to "Jim".

update() doesn't write the main object, but if you use the dot syntax, it will write() the related objects that it alters.

Parameters

array $data

A map of field name to data values to update.

Return Value

DataObject $this

DataObject castedUpdate(array $data)

Pass changes as a map, and try to get automatic casting for these fields.

Parameters

array $data

A map of field name to data values to update.

Return Value

DataObject $this

bool merge($rightObj, $priority = 'right', $includeRelations = true, $overwriteWithEmpty = false)

Merges data and relations from another object of same class, without conflict resolution. Allows to specify which dataset takes priority in case its not empty.

has_one-relations are just transferred with priority 'right'. has_many and many_many-relations are added regardless of priority.

Caution: has_many/many_many relations are moved rather than duplicated, meaning they are not connected to the merged object any longer. Caution: Just saves updated has_many/many_many relations to the database, doesn't write the updated object itself (just writes the object-properties). Caution: Does not delete the merged object. Caution: Does now overwrite Created date on the original object.

Parameters

$rightObj
$priority

String left|right Determines who wins in case of a conflict (optional)

$includeRelations

Boolean Merge any existing relations (optional)

$overwriteWithEmpty

Boolean Overwrite existing left values with empty right values. Only applicable with $priority='right'. (optional)

requireDefaultRecords()

Add default records to database. This function is called whenever the database is built, after the database tables have all been created. Overload this to add default records when the database is built, but make sure you call parent::requireDefaultRecords().

inheritedDatabaseFields()

Returns fields bu traversing the class heirachy in a bottom-up direction.

Needed to avoid getCMSFields being empty when customDatabaseFields overlooks the inheritance chain of the $db array, where a child data object has no $db array, but still needs to know the properties of its parent. This should be merged into databaseFields or customDatabaseFields.

review whether this is still needed after recent API changes

static set_session_regenerate_id($bool) deprecated

deprecated 4.0 Use the "Member.session_regenerate_id" config setting instead

No description

Parameters

$bool

static Member default_admin()

Get the default admin record if it exists, or creates it otherwise if enabled

Return Value

Member

deprecated 4.0 Use the "Member.login_marker_cookie" config setting instead

If this is called, then a session cookie will be set to "1" whenever a user logs in. This lets 3rd party tools, such as apache's mod_rewrite, detect whether a user is logged in or not and alter behaviour accordingly.

One known use of this is to bypass static caching for logged in users. This is done by putting this into _config.php

Member::set_login_marker_cookie("SS_LOGGED_IN");

And then adding this condition to each of the rewrite rules that make use of the static cache.

RewriteCond %{HTTP_COOKIE} !SS_LOGGED_IN=1

Parameters

$cookieName

string The name of the cookie to set.
