BasePage
class BasePage extends SiteTree (View source)
BasePage is the foundation which can be used for constructing your own pages.
By default it is hidden from the CMS - we rely on developers creating their own
Page
class in the mysite/code
which will extend from the BasePage.
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 |

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.

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

Return the complete map of fields on this object, including "Created", "LastEdited" and "ClassName".
Get all database columns explicitly defined on a class in DataObject::$db and DataObject::$has_one}. Resolves instances of {@link CompositeDBField into the actual database fields, rather than the name of the field which might not equate a database column.
Returns the field class if the given db field on the class is a composite field.
Returns a list of all the composite if the given db field on the class is a composite field.
Create a duplicate of this node. Doesn't affect joined data - create a custom overloading of this if you need such behaviour.

Defines a default list of filters for the search context.
Temporarily disable subclass access in data object qeur
Overloaded to also provide entities for 'Page' class which is usually located in custom code, hence textcollector picks it up for the wrong folder.

Get the absolute URL for this page on the Live site.
Returns true if this is the currently active page being used to handle this request.
Check if this page is in the currently active section (e.g. it is either current or one of its children is currently being viewed).
Check if the parent of this page has been removed (or made otherwise unavailable), and is still referenced by this child. Any such orphaned page may still require access via the CMS, but should not be shown as accessible to external users.

Stub method to get the site config, unless the current class can provide an alternate.
Pre-populate the cache of canEdit, canView, canDelete, canPublish permissions. This method will use the static can_(perm)_multiple method for efficiency.
This method is NOT a full replacement for the individual can*() methods, e.g. canEdit(). Rather than checking (potentially slow) PHP logic, it relies on the database group associations, e.g. the "CanEditType" field plus the "SiteTree_EditorGroups" many-many table. By batch checking multiple records, we can combine the queries efficiently.
Get the 'can edit' information for a number of SiteTree pages.
Get the 'can edit' information for a number of SiteTree pages.
Collate selected descendants of this page.
Return the title, description, keywords and language metatags.
Returns the object that contains the content that a user would associate with this page.
Returns true if this object has a URLSegment value that does not conflict with any other objects. This method checks for:
- A page with the same URLSegment that has a conflict
- Conflicts with actions on the parent page
- A conflict caused by a root page having the same URLSegment as a class name
Generate a URL segment based on the title provided.
Gets the URL segment for the latest draft version of this page.
Gets the URL segment for the currently published version of this page.
Rewrite a file URL on this page, after its been renamed. Triggers the onRenameLinkedAsset action on extensions.

Revert the draft changes: replace the draft content with the content on live
Determine if this page references a parent which is archived, and not available in stage
Removes the page from both live and stage, if it exists on both otherwise just removes from stage
Check if this page is new - that is, if it has yet to have been written to the database.
Get the class dropdown used in the CMS to change the class of a page. This returns the list of options in the dropdown as a Map from class name to singular name. Filters by SiteTree->canCreate(), as well as SiteTree::$needs_permission.
Returns an array of the class names of classes that are allowed to be children of this class.
Returns the class name of the default class for children of this page.
Returns the class name of the default class for the parent of this page.
Get the title for use in menus for this page. If the MenuTitle field is set it returns that, else it returns the Title field.
A flag provides the user with additional data about the current page status, for example a "removed from draft" status. Each page can have more than one status flag. Returns a map of a unique key to a (localized) title for the flag. The unique key can be reused as a CSS class. Use the 'updateStatusFlags' extension point to customize the flags.
getTreeTitle will return three html DOM elements, an empty with the class 'jstree-pageicon' in front, following by a wrapping around its MenutTitle, then following by a indicating its publication status.
Returns the page in the current page stack of the given level. Level(1) will return the main menu item that we're currently inside, etc.
Gets the depth of this page in the sitetree, where 1 is the root level
Return the CSS classes to apply to this node in the CMS tree.
Compares current draft with live version, and returns true if no draft version of this page exists but the page is still published (eg, after triggering "Delete from draft site" in the CMS).
Compares current draft with live version, and returns true if these versions differ, meaning there have been unpublished changes to the draft site.
Compares current draft with live version, and returns true if no live version exists, meaning the page was never published.
Stops extendCMSFields() being called on getCMSFields(). This is useful when you need access to fields added by subclasses of SiteTree in a extension. Call before calling parent::getCMSFields(), and reenable afterwards.
Reenables extendCMSFields() being called on getCMSFields() after it has been disabled by disableCMSFieldsExtensions().
Return a map of permission codes to add to the dropdown shown in the Security section of the CMS.
Returns 'root' if the current page has no parent, or 'subpage' otherwise
Remove linked pdf when publishing the page, as it would be out of date.

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.

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()
Get all extension instances for this specific object instance.
See get_extensions() to get all applied extension classes for this class (not the instance).

ViewableData
getCustomisedObj()
No description
setCustomisedObj(ViewableData $object)
No description
array
castingHelperPair(string $field)
Get the class a field on this object would be casted to, as well as the casting helper for casting a field to an object (see ViewableData::castingHelper() for information on casting helpers).
The returned array contains two keys:
- className: the class the field would be casted to (e.g. "Varchar")
- castingHelper: the casting helper for casting the field (e.g. "return new Varchar($fieldName)")

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_validation_enabled()
deprecated
deprecated

static
set_validation_enabled($enable)
deprecated
deprecated
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.
static

Will check all applicable ancestor classes and aggregate results.
DataObject
setDataModel(DataModel $model)
Set the DataModel
destroy()
Destroy all of this objects dependant objects and local caches.
You'll need to call this to get the memory of an object that has components or extensions freed.
DataObject
duplicate($doWrite = true)
Create a duplicate of this node. Doesn't affect joined data - create a custom overloading of this if you need such behaviour.
protected DataObject
duplicateManyManyRelations($sourceObject, $destinationObject)
Copies the many_many and belongs_many_many relations from one object to another instance of the name of object The destinationObject must be written to the database already and have an ID. Writing is performed automatically when adding the new relations.
getObsoleteClassName()
No description
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.
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.
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()
string
singular_name()
Get the user friendly singular name of this DataObject.
If the name is not defined (by redefining $singular_name in the subclass), this returns the class name.
string
i18n_singular_name()
Return the translated Singular name.
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.
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: $this->class.PLURALNAME Example: Page.PLURALNAME
string
getTitle()
Standard implementation of a title/label for a specific record. Tries to find properties 'Title' or 'Name', and falls back to the 'ID'. Useful to provide user-friendly identification of a record, e.g. in errormessages or UI-selections.
Overload this method to have a more specialized implementation, e.g. for an Address record this could be:
function getTitle() {
return "{$this->StreetNumber} {$this->StreetName} {$this->City}";
}
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.
array
toMap()
Convert this object to 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.
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.
DataObject
castedUpdate(array $data)
Pass changes as a map, and try to get automatic casting for these fields.
Doesn't write to the database. To write the data, use the write() method.
bool
merge($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.
$this
forceChange()
Forces the record to think that all its data has changed.
Doesn't write to the database. Only sets fields as changed if they are not already marked as changed.
protected 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.
ValidationResult
doValidate()
Public accessor for {DataObject::validate()}
protected
onBeforeWrite()
Event handler called before writing to the database.
You can overload this to clean up or otherwise process data before writing it to the database. Don't forget to call parent::onBeforeWrite(), though!
This called after $this->validate(), so you can be sure that your data is valid.
onAfterWrite()
Event handler called after writing to the database.
You can overload this to act upon changes made to the data after it is written. $this->changed will have a record database. Don't forget to call parent::onAfterWrite(), though!
onBeforeDelete()
Event handler called before deleting from the database.
You can overload this to clean up or otherwise process data before delete this record. Don't forget to call parent::onBeforeDelete(), though!
onAfterDelete()
No description

Does nothing if an ID is already assigned for this record
protected
writeManipulation(string $baseTable, string $now, bool $isNewRecord)
Generate and write the database manipulation for all changed fields
write(bool $showDebug = false, bool $forceInsert = false, bool $forceWrite = false, bool $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.
- $this->onBeforeWrite() gets called beforehand.
- Extensions such as Versioned will ammend the database-write to ensure that a version is saved.
writeRelations()
Writes cached relation lists to the database, if possible
DataObject
writeComponents($recursive = false)
Write the cached components to the database. Cached components could refer to two different instances of the same record.
delete()
Delete this data object.
$this->onBeforeDelete() gets called. Note that in Versioned objects, both Stage and Live will be deleted.
static
delete_by_id(string $className, int $id)
Delete the record with the given ID.
array
getClassAncestry()
Get the class ancestry, including the current class name.
The ancestry will be returned as an array of class names, where the 0th element will be the class that inherits directly from DataObject, and the last element will be the current class.
DataObject
getComponent(string $componentName)
Return a 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.
HasManyList
getComponents(string $componentName, string|null $filter = null, string|null|array $sort = null, string $join = null, string|null|array $limit = null)

string
getRelationClass($relationName)
Find the foreign class of a relation on this DataObject, regardless of the relation type.
string
getRemoteJoinField(string $component, string $type = 'has_many', bool $polymorphic = false)
Tries to find the database key on another object that is used to store a relationship to this class. If no join field can be found it defaults to 'ParentID'.
If the remote field is polymorphic then $polymorphic is set to true, and the return value is in the form 'Relation' instead of 'RelationID', referencing the composite DBField.
ManyManyList
getManyManyComponents(string $componentName, $filter = null, $sort = null, $join = null, $limit = null)
Returns a many-to-many component, as a ManyManyList.

FieldList
scaffoldSearchFields(array $_params = null)
Determine which properties on the DataObject are searchable, and map them to their default FormField representations. Used for scaffolding a searchform for ModelAdmin.
Some additional logic is included for switching field labels, based on how generic or specific the field type is.
Used by SearchContext.
FieldList
scaffoldFormFields(array $_params = null)
Scaffold a simple edit form for all properties on this dataobject, based on default FormField} mapping in {@link DBField::scaffoldFormField().
Field labels/titles will be auto generated from DataObject::fieldLabels().

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 getSettingsFields() for a different set of fields concerned with configuration aspects on the record, e.g. access control.
an
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

- FormActions within the Tab are restyled as links
- major actions can provide alternate states for richer presentation (see ssui.button widget extension)
FieldList
getFrontEndFields(array $params = null)
Used for simple frontend forms without relation editing or TabSet} behaviour. Uses {@link scaffoldFormFields() by default. To customize, either overload this method in your subclass, or extend it by DataExtension->updateFrontEndFields().

Loads all the stub fields that an initial lazy load didn't load fully.
array
getChangedFields(bool $databaseFieldsOnly = false, int $changeLevel = self::CHANGE_STRICT)
Return the fields that have changed.
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)
)
bool
isChanged(string $fieldName = null, int $changeLevel = self::CHANGE_STRICT)
Uses getChangedFields() to determine if fields have been changed since loading them from the database.
setCastedField($fieldName, $val)
Set the value of the field, using a casting object.
This is useful when you aren't sure that a date is in SQL format, for example. setCastedField() can also be used, by forms, to set related data. For example, uploaded images can be saved into the Image table.
bool
hasDatabaseField(string $field)
Returns true if the given field exists as a database column

bool
can(string $perm, Member $member = null)
This function should return true if the current user can execute this action. It can be overloaded to customise the security model for an application.
Slightly altered from parent behaviour in DataObject->can():
- Checks for existence of a method named "can<$perm>()" on the object
- Calls decorators and only returns for FALSE "vetoes"
- Falls back to Permission::check()
- Does NOT check for many-many relations named "Can<$perm>"
bool|null
extendedCan(string $methodName, Member|int $member)
Process tri-state responses from permission-alterting extensions. The extensions are expected to return one of three values:
- 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;
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
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.
Denies permission if any of the following conditions is true:
- canEdit() on any extension returns false
- canView() return false
- "CanEditType" directive is set to "Inherit" and any parent page return false for canEdit()
- "CanEditType" directive is set to "LoggedInUsers" and no user is logged in or doesn't have the CMS_Access_CMSMAIN permission code
- "CanEditType" directive is set to "OnlyTheseUsers" and user is not in the given groups
bool
canDelete(Member $member = null)
This function should return true if the current user can delete this page. It can be overloaded to customise the security model for an application.
Denies permission if any of the following conditions is true:
- canDelete() returns false on any extension
- canEdit() returns false
- any descendant page returns false for canDelete()
bool
canCreate(Member $member = null)
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 canAddChildren() to control behaviour of creating children under this page.
string
debug()
Debugging used by Debug::show()
DBField
dbObject(string $fieldName)
Return the DBField object that represents the given field.
This works similarly to obj() with 2 key differences:
- it still returns an object even when the field has no value.
- it only matches fields and not methods
- it matches foreign keys generated by has_one relationships, eg, "ParentID"
mixed
relObject(string $fieldPath)
Traverses to a DBField referenced by relationships between data objects.
The path to the related field is specified with dot separated syntax (eg: Parent.Child.Child.FieldName).
string
relField($fieldName)
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)
string
getReverseAssociation($className)
Temporary hack to return an association name, based on class, to get around the mangle of having to deal with reverse lookup of relationships to determine autogenerated foreign keys.

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.
array
searchableFields()
Get the default searchable fields for this object, as defined in the $searchable_fields list. If searchable fields are not defined on the data object, uses a default selection of summary fields.

static
prepopulate_permission_cache(string $permission = 'CanEditType', array $ids, callable|string $batchCallback = null)
Pre-populate the cache of canEdit, canView, canDelete, canPublish permissions. This method will use the static can_(perm)_multiple method for efficiency.
static array
batch_permission_check(array $ids, int $memberID, string $typeField, string $groupJoinTable, string $siteConfigMethod, string $globalPermission = null, bool $useCached = true, array $stages = array('Stage', 'Live'))
This method is NOT a full replacement for the individual can*() methods, e.g. canEdit(). Rather than checking (potentially slow) PHP logic, it relies on the database group associations, e.g. the "CanEditType" field plus the "SiteTree_EditorGroups" many-many table. By batch checking multiple records, we can combine the queries efficiently.
Caches based on $typeField data. To invalidate the cache, use SiteTree::reset() or set the $useCached property to FALSE.
static array
can_edit_multiple(array $ids, int $memberID, bool $useCached = true)
Get the 'can edit' information for a number of SiteTree pages.

string
generateURLSegment(string $title)
Generate a URL segment based on the title provided.
If Extensions wish to alter URL segment generation, they can do so by defining updateURLSegment(&$url, $title). $url will be passed by reference and should be modified. $title will contain the title that was originally used as the source of this generated URL. This lets extensions either start from scratch, or incrementally modify the generated URL.
