class TimeField extends TextField (View source)

Form field to display editable time values in an field.

Configuration

  • 'timeformat' (string): Time format compatible with Zend_Date. Usually set to default format for {@link locale} through {@link Zend_Locale_Format::getTimeFormat()}.
  • 'use_strtotime' (boolean): Accept values in PHP's built-in strtotime() notation, in addition to the format specified in timeformat. Example inputs: 'now', '11pm', '23:59:59'.

Localization

See {@link DateField}

static SS_Object
singleton()

Creates a class instance by the "singleton" design pattern.

static 
create_from_string($classSpec, $firstArg = null)

parse_class_spec($classSpec)

Parses a class-spec, such as "Versioned('Stage','Live')", as passed to create_from_string().

static SS_Object
strong_create()

static Config_ForClass|null config()

Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).

Return Value

Config_ForClass|null

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 {@link 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 {@link Object::create()}, except that classes are only overloaded if you set the $strong parameter to TRUE when using {@link 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 {@link 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 {@link Object::create()} with the class

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.

Parameters

$class
  • 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 {@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')"

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 {@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

Classname of an {@link Extension} subclass, without parameters

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

Parameters

string $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} classnames, or eval'ed classname strings with constructor arguments.

static get_extra_config_sources($class = null)

Parameters

$class

__construct(string $name, null|string $title = null, mixed $value = "")

Returns an input field.

Parameters

string $name

The internal field name, passed to forms.

null|string $title

The human-readable field label.

mixed $value

The value of the field.

mixed __call(string $method, array $arguments)

Attemps 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

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

SS_Object::uninherited_static

bool exists()

Return true if this object "exists" i.e. has a sensible value

This method should be overriden in subclasses to provide more context about the classes state. For example, a {@link DataObject} class could return false when it is deleted from the database

Return Value

bool

string parentClass()

Return Value

string

this classes parent class

bool is_a(string $class)

Check if this class is an instance of a specific class, or has that class as one of its parents

Parameters

string $class

Return Value

bool

string __toString()

Return Value

string

the class name

mixed invokeWithExtensions(string $method, mixed $argument = 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 $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 {@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 getExtensionInstance(string $extension)

Get an extension instance attached to this object by name.

Parameters

string $extension

Return Value

Extension

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

setDataModel($model)

Set the DataModel for this request.

Parameters

$model

SS_HTTPResponse|RequestHandler|string|array handleRequest(SS_HTTPRequest $request, DataModel $model)

Handles URL requests.

  • ViewableData::handleRequest() iterates through each rule in {@link self::$url_handlers}.
    • If the rule matches, the named method will be called.
    • If there is still more URL to be processed, then handleRequest() is called on the object that that method returns.

Once all of the URL has been processed, the final result is returned. However, if the final result is an array, this array is interpreted as being additional template data to customise the 2nd to last result with, rather than an object in its own right. This is most frequently used when a Controller's action will return an array of data with which to customise the controller.

Parameters

SS_HTTPRequest $request

The {@link SS_HTTPRequest} object that is reponsible for distributing URL parsing

DataModel $model

Return Value

SS_HTTPResponse|RequestHandler|string|array

array|null allowedActions(string $limitToClass = null)

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

Parameters

string $limitToClass

Return Value

array|null

bool hasAction(string $action)

Checks if this request handler has a specific action, even if the current user cannot access it.

Includes class ancestry and extensions in the checks.

Parameters

string $action

Return Value

bool

checkAccessAction($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

$action

httpError(int $errorCode, string $errorMessage = null)

Throws a HTTP error response encased in a {@link SS_HTTPResponse_Exception}, which is later caught in {@link RequestHandler::handleAction()} and returned to the user.

Parameters

int $errorCode
string $errorMessage

Plaintext error message

SS_HTTPRequest|NullHTTPRequest getRequest()

Returns the SS_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 SS_HTTPRequest} object.

setRequest($request)

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

Parameters

$request

Return a link to this field.

Parameters

string $action

Return Value

string

static string name_to_label(string $fieldName)

string getTemplate()

Return Value

string

string getFieldHolderTemplate()

Return Value

string

$this setFieldHolderTemplate(string $fieldHolderTemplate)

string Field(array $properties = array())

Returns the form field.

Although FieldHolder is generally what is inserted into templates, all of the field holder templates make use of $Field. It's expected that FieldHolder will give you the "complete" representation of the field on the form, whereas Field will give you the core editing widget, such as an input tag.

Parameters

array $properties

Return Value

string

string FieldHolder(array $properties = array())

Returns a "field holder" for this field.

Forms are constructed by concatenating a number of these field holders.
