class LeftAndMain extends Controller implements PermissionProvider

LeftAndMain is the parent class of all the two-pane views in the CMS.

If you are wanting to add more areas to the CMS, you can do it by subclassing LeftAndMain.

This is essentially an abstract class which should be subclassed. See {@link CMSMain} for a good example.

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

SCHEMA_HEADER

Form schema header identifier

Config options

url_segment string The current url segment attached to the LeftAndMain instance
url_rule string
menu_title string
menu_icon string
menu_priority int
url_priority int
tree_class string A subclass of {@link DataObject}.
help_link string
admin_themes array Assign themes to use for cms
required_permission_codes array Codes which are required from the current user to view this controller.
session_namespace string Namespace for session info, e.g. current record.
extra_requirements_javascript array Register additional requirements through the {@link Requirements} class.
extra_requirements_css array YAML configuration example: LeftAndMain: extra_requirements_css: mysite/css/mystyle.css: media: screen
extra_requirements_themedCss array
session_keepalive_ping bool If true, call a keepalive ping every 5 minutes from the CMS interface, to ensure that the session never dies.
frame_options string Value of X-Frame-Options header
section_name string|null The configuration passed to the supporting JS for each CMS section includes a 'name' key that by default matches the FQCN of the current class. This setting allows you to change the key if necessary (for example, if you are overloading CMSMain or another core class and want to keep the core JS - which depends on the core class names - functioning, you would need to set this to the FQCN of the class you are overloading).
help_links array The urls used for the links in the Help dropdown in the backend
application_link string The href for the anchor on the Silverstripe logo
application_name string The application name

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

in CustomMethods at line 146
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

in CustomMethods at line 176
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

in Extensible at line 172
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

in Extensible at line 236
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

in Extensible at line 278
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.

in Extensible at line 312
static array|null get_extra_config_sources(string $class = null)

Get extra config sources for this class

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

Return Value

array|null

in Extensible at line 373
static bool has_extension(string $classOrExtension, string $requiredExtension = null, boolean $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.
boolean $strict if the extension has to match the required extension and not be a subclass

Return Value

bool Flag if the extension exists

in Extensible at line 415
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)

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

in Extensible at line 450
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

in Extensible at line 497
Extension|null getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension|null

in Extensible at line 526
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

in Extensible at line 540
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.

in Injectable at line 26
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

string ThemeDir() deprecated

deprecated 4.0.0:5.0.0 Use $resourcePath or $resourceURL template helpers instead

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.

HTTPResponse|RequestHandler|string|array handleRequest(HTTPRequest $request)

Executes this controller, and return an {@link HTTPResponse} object with the result.

This method defers to {@link RequestHandler->handleRequest()} to determine which action should be executed

Note: You should rarely need to overload handleRequest() - this kind of change is only really appropriate for things like nested controllers - {@link ModelAsController} and {@link RootURLController} are two examples here. If you want to make more orthodox functionality, it's better to overload {@link init()} or {@link index()}.

Important: If you are going to overload handleRequest, make sure that you start the method with $this->beforeHandleRequest() and end the method with $this->afterHandleRequest()

Parameters

HTTPRequest $request The object that is reponsible for distributing URL parsing

Return Value

HTTPResponse|RequestHandler|string|array

in RequestHandler at line 345
array|null allowedActions(string $limitToClass = null)

Get a array of allowed actions defined on this controller, any parent classes or extensions.

Caution: Since 3.1, allowed_actions definitions only apply to methods on the controller they're defined on, so it is recommended to use the $class argument when invoking this method.

Parameters

string $limitToClass

Return Value

array|null

in Controller at line 427
bool hasAction(string $action)

Parameters

string $action

Return Value

bool

in RequestHandler at line 456
bool checkAccessAction(string $action)

Check that the given action is allowed to be called from a URL.

It will interrogate {@link self::$allowed_actions} to determine this.

Parameters

string $action

Return Value

bool

Exceptions

Exception

in RequestHandler at line 516
httpError(int $errorCode, string $errorMessage = null)

Parameters

int $errorCode
string $errorMessage Plaintext error message

Exceptions

HTTPResponse_Exception

in RequestHandler at line 538
HTTPRequest getRequest()

Returns the HTTPRequest object that this controller is using.

Returns a placeholder {@link NullHTTPRequest} object unless {@link handleAction()} or {@link handleRequest()} have been called, which adds a reference to an actual {@link HTTPRequest} object.

Return Value

HTTPRequest

in Controller at line 145
$this setRequest(HTTPRequest $request)

Typically the request is set through {@link handleAction()} or {@link handleRequest()}, but in some based we want to set it manually.

Parameters

HTTPRequest $request

Return Value

$this

You should implement a Link() function in your subclass of LeftAndMain, to point to the URL of that particular controller.

Parameters

string $action Optional action

Return Value

string

at line 798
HTTPResponse redirect(string $url, int $code = 302)

Overloaded redirection logic to trigger a fake redirect on ajax requests.

While this violates HTTP principles, its the only way to work around the fact that browsers handle HTTP redirects opaquely, no intervention via JS is possible. In isolation, that's not a problem - but combined with history.pushState() it means we would request the same redirection URL twice if we want to update the URL as well. See LeftAndMain.js for the required jQuery ajaxComplete handlers.

Parameters

string $url
int $code

Return Value

HTTPResponse

in RequestHandler at line 601
string getBackURL()

HTTPResponse redirectBack()

Redirect back. Uses either the HTTP-Referer or a manually set request-variable called "BackURL".

This variable is needed in scenarios where HTTP-Referer is not sent (e.g when calling a page by location.href in IE). If none of the two variables is available, it will redirect to the base URL (see {@link Director::baseURL()}).

Return Value

HTTPResponse

in Controller at line 120

Form EditForm(HTTPRequest $request = null)

Retrieves an edit form, either for display, or to process submitted data.

Also used in the template rendered through {@link Right()} in the $EditForm placeholder.

This is a "pseudo-abstract" methoed, usually connected to a {@link getEditForm()} method in an entwine subclass. This method can accept a record identifier, selected either in custom logic, or through {@link currentPageID()}. The form usually construct itself from {@link DataObject->getCMSFields()} for the specific managed subclass defined in {@link LeftAndMain::$tree_class}.

Parameters

HTTPRequest $request Passed if executing a HTTPRequest directly on the form. If empty, this is invoked as $EditForm in the template

Return Value

Form Should return a form regardless wether a record has been found. Form might be readonly if the current user doesn't have the permission to edit the record.

at line 1363
Form getEditForm(int $id = null, FieldList $fields = null)

Calls {@link SiteTree->getCMSFields()} by default to determine the form fields to display.

Parameters

int $id
FieldList $fields

Return Value

Form

at line 1491
Form EmptyForm()

Returns a placeholder form, used by {@link getEditForm()} if no record is selected.

at line 1527
string Tools()

Renders a panel containing tools which apply to all displayed "content" (mostly through {@link EditForm()}), for example a tree navigation or a filter panel.

Auto-detects applicable templates by naming convention: "_Tools.ss", and takes the most specific template (see {@link getTemplatesWithSuffix()}). To explicitly disable the panel in the subclass, simply create a more specific, empty template.

Return Value

string HTML

at line 1549
string EditFormTools()

Renders a panel containing tools which apply to the currently displayed edit form.

The main difference to {@link Tools()} is that the panel is displayed within the element structure of the form panel (rendered through {@link EditForm}). This means the panel will be loaded alongside new forms, and refreshed upon save, which can mean a performance hit, depending on how complex your panel logic gets. Any form fields contained in the returned markup will also be submitted with the main form, which might be desired depending on the implementation details.

Return Value
