class i18n extends SS_Object implements TemplateGlobalProvider, Flushable (View source)

Base-class for storage and retrieval of translated entities.

Please see the 'translatable' module for managing translations of database-content.

Usage

PHP:

_t('MyNamespace.MYENTITY', 'My default natural language value');
_t('MyNamespace.MYENTITY', 'My default natural language value', 'My explanatory context');
sprintf(_t('MyNamespace.MYENTITY', 'Counting %s things'), 42);

Templates:

<%t MyNamespace.MYENTITY 'My default natural language value' %>
<%t MyNamespace.MYENTITY 'Counting %s things' s=$ThingsCount %>
<%t MyNamespace.MYENTITY 'Counting {count} things' count=$ThingsCount %>

Javascript (see framework/javascript/i18n.js):

ss.i18n._t('MyEntity.MyNamespace','My default natural language value');

File-based i18n-translations always have a "locale" (e.g. 'en_US'). Common language names (e.g. 'en') are mainly used in the 'translatable' module database-entities.

Text Collection

Features a "textcollector-mode" that parses all files with a certain extension (currently .php and .ss) for new translatable strings. Textcollector will write updated string-tables to their respective folders inside the module, and automatically namespace entities to the classes/templates they are found in (e.g. $lang['en_US']['AssetAdmin']['UPLOADFILES']).

Caution: Does not apply any character-set conversion, it is assumed that all content is stored and represented in UTF-8 (Unicode). Please make sure your files are created with the correct character-set, and your HTML-templates render UTF-8.

Caution: The language file has to be stored in the same module path as the "filename namespaces" on the entities. So an entity stored in $lang['en_US']['AssetAdmin']['DETAILSTAB'] has to in the language file cms/lang/en_US.php, as the referenced file (AssetAdmin.php) is stored in the "cms" module.

Locales

For the i18n class, a "locale" consists of a language code plus a region code separated by an underscore, for example "de_AT" for German language ("de") in the region Austria ("AT"). See http://www.w3.org/International/articles/language-tags/ for a detailed description.

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.

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

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.

Parameters

string $method

The name of the method to hook into

callable $callback

The callback to execute

static SS_Object create()

An implementation of the factory method, allows you to create an instance of a class

This method first for strong class overloads (singletons & DB interaction), then custom class overloads. If an overload is found, an instance of this is returned rather than the original class. To overload a class, use Object::useCustomClass()

This can be called in one of two ways - either calling via the class directly, or calling on Object and passing the class name as the first parameter. The following are equivalent: $list = DataList::create('SiteTree'); $list = SiteTree::get();

Return Value

SS_Object

static SS_Object singleton()

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

It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).

Return Value

SS_Object

The singleton instance

static create_from_string($classSpec, $firstArg = null)

Create an object from a string representation. It treats it as a PHP constructor without the 'new' keyword. It also manages to construct the object without the use of eval().

Construction itself is done with Object::create(), so that Object::useCustomClass() calls are respected.

Object::create_from_string("Versioned('Stage','Live')") will return the result of Versioned::create('Stage', 'Live);

It is designed for simple, clonable objects. The first time this method is called for a given string it is cached, and clones of that object are returned.

If you pass the $firstArg argument, this will be prepended to the constructor arguments. It's impossible to pass null as the firstArg argument.

Object::create_from_string("Varchar(50)", "MyField") will return the result of Vachar::create('MyField', '50');

Arguments are always strings, although this is a quirk of the current implementation rather than something that can be relied upon.

Parameters

$classSpec
$firstArg

static parse_class_spec($classSpec)

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

Returns a 2-elemnent array, with classname and arguments

Parameters

$classSpec

static SS_Object strong_create()

Similar to Object::create(), except that classes are only overloaded if you set the $strong parameter to TRUE when using Object::useCustomClass()

Return Value

SS_Object

static useCustomClass(string $oldClass, string $newClass, bool $strong = false)

This class allows you to overload classes with other classes when they are constructed using the factory method Object::create()

Parameters

string $oldClass

the class to replace

string $newClass

the class to replace it with

bool $strong

allows you to enforce a certain class replacement under all circumstances. This is used in singletons and DB interaction classes

static string getCustomClass(string $class)

If a class has been overloaded, get the class name it has been overloaded with - otherwise return the class name

Parameters

string $class

the class to check

Return Value

string

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

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

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

Parameters

string $classOrExtension

Class that should be extended - has to be a subclass of Object

string $extension

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

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

static remove_extension(string $extension)

Remove an extension from a class.

Keep in mind that this won't revert any datamodel additions of the extension at runtime, unless its used before the schema building kicks in (in your _config.php). Doesn't remove the extension from any Object instances which are already created, but will have an effect on new extensions. Clears any previously created singletons through singleton() to avoid side-effects from stale extension information.

Add support for removing extensions with parameters

Parameters

string $extension

Classname of an Extension subclass, without parameters

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

No description

Parameters

string $class
bool $includeArgumentString

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 DataExtension classnames, or eval'ed classname strings with constructor arguments.

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 DataObject class could return false when it is deleted from the database

Return Value

bool

Return Value

mixed

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

Run the given function on all of this object's extensions. Note that this method originally returned void, so if you wanted to return results, you're hosed

Currently returns an array, with an index resulting every time the function is called. Only adds returns if they're not NULL, to avoid bogus results from methods just defined on the parent extension. This is important for permission-checks through extend, as they use min() to determine if any of the returns is FALSE. As min() doesn't do type checking, an included NULL return would fail the permission checks.

The extension methods are defined during __construct()} in {@link defineMethods().

Parameters

string $method

the name of the method to call on each extension

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

Return Value

array

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 $extension_instances. Extension instances are initialized at constructor time, meaning if you use add_extension() afterwards, the added extension will just be added to new instances of the extended class. Use the static method has_extension() to check if a class (not an instance) has a specific extension.

Caution: Don't use singleton()->hasExtension() as it will give you inconsistent results based on when the singleton was first accessed.

Parameters

string $extension

Classname of an Extension subclass without parameters

Return Value

bool

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).

string $context

(optional) If the string can be difficult to translate by any reason, you can help translators with some more info using this param

array $injection

(optional) array of key value pairs that are used to replace corresponding expressions in {curly brackets} in the $string. The injection array can also be used as the their argument to the _t() function. The injection array can be the second, third or fourth parameter.

array

Returns an array of items. Each key => value pair is one of three forms:

  • template name (no key)
  • template name => method name
  • template name => array(), where the array can contain these key => value pairs
    • "method" => method name
    • "casting" => casting class to use (i.e., Varchar, HTMLText, etc)
