class SiteTree extends DataObject implements PermissionProvider, i18nEntityProvider, CMSPreviewable, Resettable, Flushable, MemberCacheFlusher (View source)

Basic data-object representing all pages within the site tree. All page types that live within the hierarchy should inherit from this. In addition, it contains a number of static methods for querying the site tree and working with draft and published states.

URLs

A page is identified during request handling via its "URLSegment" database column. As pages can be nested, the full path of a URL might contain multiple segments. Each segment is stored in its filtered representation (through {@link URLSegmentFilter}). The full path is constructed via {@link Link()}, {@link RelativeLink()} and {@link AbsoluteLink()}. You can allow these segments to contain multibyte characters through {@link URLSegmentFilter::$default_allow_multibyte}.

Traits

Allows an object to have extensions applied to it.

A class that can be instantiated or replaced via DI

Provides extensions to this object to integrate it with standard config API methods.

Allows an object to declare a set of custom methods

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

CREATE_OBJECT

Value for 2nd argument to constructor, indicating that a new record is being created Setters will be called on fields passed, and defaults will be populated

CREATE_SINGLETON

Value for 2nd argument to constructor, indicating that a record is a singleton representing the whole type, e.g. to call requireTable() in dev/build Defaults will not be populated and data passed will be ignored

CREATE_HYDRATED

Value for 2nd argument to constructor, indicating that a record is being hydrated from the database Setter methods are not called, and population via private static $defaults will not occur.

CREATE_MEMORY_HYDRATED

Value for 2nd argument to constructor, indicating that a record is being hydrated from memory. This can be used to initialised a record that doesn't yet have an ID. Setter methods are not called, and population via private static $defaults will not occur.

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 {@link Extensions}, {@link Object::createMethod()} or {@link Object::addWrapperMethod()}

Parameters

string $method
array $arguments

Return Value

mixed

Exceptions

BadMethodCallException

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

Parameters

string $method

Return Value

bool

array allMethodNames(bool $custom = false)

Return the names of all the methods available on this object

Parameters

bool $custom

include methods added dynamically at runtime

Return Value

array

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 {@link Object::$extensions} array. See {@link SiteTree::$extensions} for examples. Keep in mind that the extension will only be applied to new instances, not existing ones (including all instances created through {@link singleton()}).

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of {@link Object}

string $extension

Subclass of {@link Extension} with optional parameters as a string, e.g. "Versioned" or "Translatable('Param')"

Return Value

bool

Flag if the extension was added

See also

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

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 {@link Object} instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through {@link singleton()} to avoid side-effects from stale extension information.

Parameters

string $extension

class name of an {@link Extension} subclass, without parameters

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

Parameters

string $class

If omitted, will get extensions for the current class

bool $includeArgumentString

Include the argument string in the return array, FALSE would return array("Versioned"), TRUE returns array("Versioned('Stage','Live')").

Return Value

array

Numeric array of either {@link DataExtension} class names, or eval'ed class name strings with constructor arguments.

static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

Parameters

string $class

Name of class. If left null will return for the current class

Return Value

array|null

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))

Parameters

string $classOrExtension

Class to check extension for, or the extension name to check if the second argument is null.

string $requiredExtension

If the first argument is the parent class, this is the extension to check. If left null, the first parameter will be treated as the extension.

bool $strict

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

Return Value

bool

Flag if the extension exists

array invokeWithExtensions(string $method, mixed $a1 = null, mixed $a2 = null, mixed $a3 = null, mixed $a4 = null, mixed $a5 = null, mixed $a6 = null, mixed $a7 = null)

Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array

Parameters

string $method

the method name to call

mixed $a1
mixed $a2
mixed $a3
mixed $a4
mixed $a5
mixed $a6
mixed $a7

Return Value

array

List of results with nulls filtered out

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 {@link __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|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

bool hasExtension(string $extension)

Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link 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 {@link Extension} subclass without parameters

Return Value

bool

Extension[] getExtensionInstances()

Get all extension instances for this specific object instance.

See {@link 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.

Return Value

Extension[]

Map of {@link DataExtension} instances, keyed by classname.

static Injectable create(array ...$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'); $list = SiteTree::get();

Parameters

array ...$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

static Config_ForClass config()

DataObject duplicate(bool $doWrite = true, array|null|false $relations = null)

Create a duplicate of this node. Can duplicate many_many relations

Parameters

bool $doWrite

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

array|null|false $relations

List of relations to duplicate. Will default to cascade_duplicates if null. Set to 'false' to force none. Set to specific array of names to duplicate to override these. Note: If using versioned, this will additionally failover to owns config.

Return obsolete class name, if this is no longer a valid class

Return Value

string

string getClassName()

Return Value

string

$this setClassName(string $className)

Set the ClassName attribute. {@link $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 {@link newClassInstance()} for this purpose, or destroy and reinstanciate the record.

Parameters

string $className

The new ClassName attribute (a subclass of {@link DataObject})

Return Value

$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 {@link 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).

User friendly translated singular name of this DataObject

string plural_name()

Default plural name for page / sitetree

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

Return Value

string

User friendly translated plural name of this DataObject

string getTitle()

Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections.

Overload this method to have a more specialized implementation, e.g. for an Address record this could be: function getTitle() { return "{$this->StreetNumber} {$this->StreetName} {$this->City}"; }

Return Value

string

DataObject data()

Returns the associated database record - in this case, the object itself.

This is included so that you can call $dataOrController->data() and get a DataObject all the time.

Return Value

DataObject

Associated database record

array toMap()

Convert this object to a map.

Note that it has the following quirks:

  • custom getters, including those that adjust the result of database fields, won't be executed
  • NULL values won't be returned.

Return Value

array

The data as a map.

array getQueriedDatabaseFields()

Return all currently fetched database fields.

This function is similar to toMap() but doesn't trigger the lazy-loading of all unfetched fields. Obviously, this makes it a lot faster.

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".

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

When using this method with user supplied data, it's very important to whitelist the allowed keys.

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.

Doesn't write to the database. To write the data, use the write() method.

Parameters

array $data

A map of field name to data values to update.

Return Value

DataObject

$this

bool merge(DataObject $rightObj, string $priority = 'right', bool $includeRelations = true, bool $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

DataObject $rightObj
string $priority

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

bool $includeRelations

Merge any existing relations (optional)

bool $overwriteWithEmpty

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

Return Value

bool

$this forceChange()

Forces the record to think that all its data has changed.

Doesn't write to the database. Force-change preseved until next write. Existing CHANGE_VALUE or CHANGE_STRICT values are preserved.

Return Value

$this

ValidationResult validate()

Validate the current object.

By default, there is no validation - objects are always valid! However, you can overload this method in your DataObject sub-classes to specify custom validation, or use the hook through DataExtension.

Invalid objects won't be able to be written - a warning will be thrown and no write will occur. onBeforeWrite() and onAfterWrite() won't get called either.

It is expected that you call validate() in your own application to test that an object is valid before attempting a write, and respond appropriately if it isn't.

Return Value

ValidationResult

ValidationResult doValidate()

Public accessor for {see DataObject::validate()}

Return Value

ValidationResult

ArrayList findCascadeDeletes(bool $recursive = true, ArrayList $list = null)

Find all objects that will be cascade deleted if this object is deleted

Notes:

  • If this object is versioned, objects will only be searched in the same stage as the given record.
  • This will only be useful prior to deletion, as post-deletion this record will no longer exist.

Parameters

bool $recursive

True if recursive

ArrayList $list

Optional list to add items to

Return Value

ArrayList

list of objects

DataObject populateDefaults()

Load the default values in from the self::$defaults array.

Will traverse the defaults of the current class and all its parent classes. Called by the constructor when creating new records.

Return Value

DataObject

$this

write(bool $showDebug = false, bool $forceInsert = false, bool $forceWrite = false, bool|array $writeComponents = false)

Writes all changes to this object to the database.

  • It will insert a record whenever ID isn't set, otherwise update.
  • All relevant tables will be updated.
  • $this->onBeforeWrite() gets called beforehand.
  • Extensions such as Versioned will ammend the database-write to ensure that a version is saved.

Parameters

bool $showDebug

Show debugging information

bool $forceInsert

Run INSERT command rather than UPDATE, even if record already exists

bool $forceWrite

Write to database even if there are no changes

bool|array $writeComponents

Call write() on all associated component instances which were previously retrieved through {@link getComponent()}, {@link getComponents()} or {@link getManyManyComponents()}. Default to false. The parameter can also be provided in the form of an array: ['recursive' => true, skip => ['Page'=>[1,2,3]]. This avoid infinite loops when one DataObject are components of each other.

Exceptions

ValidationException

Exception that can be caught and handled by the calling function

writeRelations()

Writes cached relation lists to the database, if possible

DataObject writeComponents(bool $recursive = false, array $skip = [])

Write the cached components to the database. Cached components could refer to two different instances of the same record.

Parameters

bool $recursive

Recursively write components

array $skip

List of DataObject references to skip

Return Value

DataObject

$this

delete()

Delete this data object.

$this->onBeforeDelete() gets called. Note that in Versioned objects, both Stage and Live will be deleted.

Parameters

string $className

The class name of the record to be deleted

int $id

ID of record to be deleted

Return Value

array

Class ancestry

DataObject getComponent(string $componentName)

Return a unary component object from a one to one relationship, as a DataObject.

If no component is available, an 'empty component' will be returned for non-polymorphic relations, or for polymorphic relations with a class set.

Parameters

string $componentName

Name of the component

Return Value

DataObject

The component object. It's exact type will be that of the component.

Exceptions

DataList|DataObject inferReciprocalComponent(string $remoteClass, string $remoteRelation)

Given a relation declared on a remote class, generate a substitute component for the opposite side of the relation.

Notes on behaviour:

  • This can still be used on components that are defined on both sides, but do not need to be.
  • All has_ones on remote class will be treated as local has_many, even if they are belongs_to
  • Polymorphic relationships do not have two natural endpoints (only on one side) and thus attempting to infer them will return nothing.
  • Cannot be used on unsaved objects.

Parameters

string $remoteClass
string $remoteRelation

Return Value

DataList|DataObject

The component, either as a list or single object

Exceptions

BadMethodCallException
InvalidArgumentException

FieldList scaffoldSearchFields(array $_params = null)

Determine which properties on the DataObject are searchable, and map them to their default {@link FormField} representations. Used for scaffolding a searchform for {@link ModelAdmin}.

Some additional logic is included for switching field labels, based on how generic or specific the field type is.

Used by {@link SearchContext}.

Parameters

array $_params

'fieldClasses': Associative array of field names as keys and FormField classes as values 'restrictFields': Numeric array of a field name whitelist

Return Value

FieldList

FieldList scaffoldFormFields(array $_params = null)

Parameters

array $_params

Associative array passing through properties to {@link FormScaffolder}.

Return Value

FieldList

FieldList getCMSFields()

Returns a FieldList with which to create the main editing form.

You can override this in your child classes to add extra fields - first get the parent fields using parent::getCMSFields(), then use addFieldToTab() on the FieldList.

See {@link getSettingsFields()} for a different set of fields concerned with configuration aspects on the record, e.g. access control.

Return Value

FieldList

Returns a TabSet for usage within the CMS - don't use for frontend forms.

FieldList getCMSActions()

Get the actions available in the CMS for this page - eg Save, Publish.

Frontend scripts and styles know how to handle the following FormFields:

  • top-level FormActions appear as standalone buttons
  • top-level CompositeField with FormActions within appear as grouped buttons
  • TabSet & Tabs appear as a drop ups
  • FormActions within the Tab are restyled as links
  • major actions can provide alternate states for richer presentation (see ssui.button widget extension)

Return Value

FieldList

an Empty FieldList(); need to be overload by solid subclass

CompositeValidator getCMSCompositeValidator()

When extending this class and overriding this method, you will need to instantiate the CompositeValidator by calling parent::getCMSCompositeValidator(). This will ensure that the appropriate extension point is also invoked.

You can also update the CompositeValidator by creating an Extension and implementing the updateCMSCompositeValidator(CompositeValidator $compositeValidator) method.

Return Value

CompositeValidator

See also

CompositeValidator for examples of implementation

FieldList getFrontEndFields(array $params = null)

Used for simple frontend forms without relation editing or {@link TabSet} behaviour. Uses {@link scaffoldFormFields()} by default. To customize, either overload this method in your subclass, or extend it by {@link DataExtension->updateFrontEndFields()}.

Parameters

array $params

See {@link scaffoldFormFields()}

Return Value

FieldList

Always returns a simple field collection without TabSet.

array getChangedFields(bool|array $databaseFieldsOnly = false, int $changeLevel = self::CHANGE_STRICT)

Return the fields that have changed since the last write.

The change level affects what the functions defines as "changed":

  • Level CHANGE_STRICT (integer 1) will return strict changes, even !== ones.
  • Level CHANGE_VALUE (integer 2) is more lenient, it will only return real data changes, for example a change from 0 to null would not be included.

Example return: array( 'Title' = array('before' => 'Home', 'after' => 'Home-Changed', 'level' => DataObject::CHANGE_VALUE) )

Parameters

bool|array $databaseFieldsOnly

Filter to determine which fields to return. Set to true to return all database fields, or an array for an explicit filter. false returns all fields.

int $changeLevel

The strictness of what is defined as change. Defaults to strict

Return Value

array

bool isChanged(string $fieldName = null, int $changeLevel = self::CHANGE_STRICT)

Parameters

string $fieldName

Name of the database field to check, will check for any if not given

int $changeLevel

See {@link getChangedFields()}

Return Value

bool

$this setCastedField(string $fieldName, mixed $value)

Set the value of the field, using a casting object.

Parameters

string $fieldName
mixed $value

New field value

Return Value

$this

bool hasDatabaseField(string $field)

Returns true if the given field exists as a database column

Parameters

string $field

Name of the field

Return Value

bool

bool can(string $perm, Member $member = null, array $context = [])

This function should return true if the current user can execute this action. It can be overloaded to customise the security model for an application.

Slightly altered from parent behaviour in {@link DataObject->can()}:

  • Checks for existence of a method named "can<$perm>()" on the object
  • Calls decorators and only returns for FALSE "vetoes"
  • Falls back to {@link Permission::check()}
  • Does NOT check for many-many relations named "Can<$perm>"

Parameters

string $perm

The permission to be checked, such as 'View'.

Member $member

The member whose permissions need checking. Defaults to the currently logged in user.

array $context

Additional $context to pass to extendedCan()

Return Value

bool

True if the the member is allowed to do the given action

bool|null extendedCan(string $methodName, Member|int $member, array $context = [])

  • false: Disallow this permission, regardless of what other extensions say
    • true: Allow this permission, as long as no other extensions return false
    • NULL: Don't affect the outcome

This method itself returns a tri-state value, and is designed to be used like this:

$extended = $this->extendedCan('canDoSomething', $member); if($extended !== null) return $extended; else return $normalValue;

Parameters

string $methodName

Method on the same object, e.g. {@link canEdit()}

Member|int $member
array $context

Optional context

Return Value

bool|null

bool canView(Member $member = null)

This function should return true if the current user can view this page. It can be overloaded to customise the security model for an application.

Denies permission if any of the following conditions is true:

  • canView() on any extension returns false
  • "CanViewType" directive is set to "Inherit" and any parent page return false for canView()
  • "CanViewType" directive is set to "LoggedInUsers" and no user is logged in
  • "CanViewType" directive is set to "OnlyTheseUsers" and user is not in the given groups

Parameters

Member $member

Return Value

bool

bool canEdit(Member $member = null)

This function should return true if the current user can edit this page. It can be overloaded to customise the security model for an application.

  • canDelete() returns false on any extension
  • canEdit() returns false
  • any descendant page returns false for canDelete()

Parameters

Member $member

Return Value

bool

bool canCreate(Member $member = null, array $context = [])

This function should return true if the current user can create new pages of this class, regardless of class. It can be overloaded to customise the security model for an application.

By default, permission to create at the root level is based on the SiteConfig configuration, and permission to create beneath a parent is based on the ability to edit that parent page.

Use {@link canAddChildren()} to control behaviour of creating children under this page.

Parameters

Member $member

  • it only matches fields and not methods
  • it matches foreign keys generated by has_one relationships, eg, "ParentID"

Parameters

string $fieldName

Name of the field

Return Value

DBField

The field as a DBField object

mixed relObject(string $fieldPath)

Traverses to a DBField referenced by relationships between data objects.

The path to the related field is specified with dot separated syntax (eg: Parent.Child.Child.FieldName).

If a relation is blank, this will return null instead. If a relation name is invalid (e.g. non-relation on a parent) this can throw a LogicException.

Parameters

string $fieldPath

List of paths on this object. All items in this path must be ViewableData implementors

Return Value

mixed

DBField of the field on the object or a DataList instance.

Exceptions

LogicException

Traverses to a field referenced by relationships between data objects, returning the value The path to the related field is specified with dot separated syntax (eg: Parent.Child.Child.FieldName)

Parameters

string $fieldName

string

Return Value

mixed

Will return null on a missing value

Parameters

string $callerClass

The class of objects to be returned

string|array $filter

A filter to be inserted into the WHERE clause. Supports parameterised queries. See SQLSelect::addWhere() for syntax examples.

string|array $sort

A sort expression to be inserted into the ORDER BY clause. If omitted, self::$default_sort will be used.

string $join
