ShortcodeParser
class ShortcodeParser (View source)
A simple parser that allows you to map BBCode-like "shortcodes" to an arbitrary callback.
It is a simple regex based parser that allows you to replace simple bbcode-like tags within a DBHTMLText or DBHTMLVarchar field when rendered into a template. The API is inspired by and very similar to the Wordpress implementation of shortcodes.

Methods
An implementation of the factory method, allows you to create an instance of a class
Creates a class instance by the "singleton" design pattern.
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
Gets the uninherited value for the given config option
Attempts to locate and call a method dynamically added to a class at runtime if a default cannot be located
Return the names of all the methods available on this object
Add an extension to a specific class.
No description
Get extra config sources for this class
Return TRUE if a class has a specified extension.
Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array
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
Get an extension instance attached to this object by name.
Returns TRUE if this object instance has a specific extension applied in {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link has_extension()} to check if a class (not an instance) has a specific extension.
Get all extension instances for this specific object instance.
No description
No description
Get the {@link ShortcodeParser} instance that is attached to a particular identifier.
Get the currently active/default {@link ShortcodeParser} instance.
Set the identifier to use for the current active/default {@link ShortcodeParser} instance.
Register a shortcode, and attach it to a PHP callback.
Check if a shortcode has been registered.
Remove a specific registered shortcode.
Get an array containing information about registered shortcodes
Remove all registered shortcodes.
Call a shortcode and return its replacement text Returns false if the shortcode isn't registered
Return the text to insert in place of a shoprtcode.
Look through a string that contains shortcode tags and pull out the locations and details of those tags
Parse a string, and replace any registered shortcodes within it with the result of the mapped callback.
Details
static Injectable
create(array ...$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();
static Injectable
singleton(string $class = null)
Creates a class instance by the "singleton" design pattern.
It will always return the same instance for this class, which can be used for performance reasons and as a simple way to access instance methods which don't rely on instance data (e.g. the custom SilverStripe static handling).
static Config_ForClass
config()
Get a configuration accessor for this class. Short hand for Config::inst()->get($this->class, .....).
mixed
stat(string $name)
deprecated
deprecated
Get inherited config value
mixed
uninherited(string $name)
Gets the uninherited value for the given config option

Update the config value for a given property
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()}
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
array
allMethodNames(bool $custom = false)
Return the names of all the methods available on this object
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()}).
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.
static array
get_extensions(string $class = null, bool $includeArgumentString = false)
static array|null
get_extra_config_sources(string $class = null)
Get extra config sources for this class
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))
array
invokeWithExtensions(string $method, mixed ...$arguments)
Calls a method if available on both this object and all applied {@link Extensions}, and then attempts to merge all results into an array
array
extend(string $method, mixed ...$arguments)
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()}.
Extension|null
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 {@link $extension_instances}. Extension instances are initialized at constructor time, meaning if you use {@link add_extension()} afterwards, the added extension will just be added to new instances of the extended class. Use the static method {@link has_extension()} to check if a class (not an instance) has a specific extension.
Caution: Don't use singleton(
Extension[]
getExtensionInstances()
Get all extension instances for this specific object instance.
See {@link get_extensions()} to get all applied extension classes for this class (not the instance).
This method also provides lazy-population of the extension_instances property.
__construct()
img_shortcode($attrs)
static ShortcodeParser
get(string $identifier = 'default')
Get the {@link ShortcodeParser} instance that is attached to a particular identifier.
static ShortcodeParser
get_active()
Get the currently active/default {@link ShortcodeParser} instance.
static
set_active(string $identifier)
Set the identifier to use for the current active/default {@link ShortcodeParser} instance.
$this
register(string $shortcode, callable $callback)
Register a shortcode, and attach it to a PHP callback.
The callback for a shortcode will have the following arguments passed to it:
- Any parameters attached to the shortcode as an associative array (keys are lower-case).
- Any content enclosed within the shortcode (if it is an enclosing shortcode). Note that any content within this will not have been parsed, and can optionally be fed back into the parser.
- The {@link ShortcodeParser} instance used to parse the content.
- The shortcode tag name that was matched within the parsed content.
- An associative array of extra information about the shortcode being parsed.
bool
registered(string $shortcode)
Check if a shortcode has been registered.
unregister(string $shortcode)
Remove a specific registered shortcode.
array
getRegisteredShortcodes()
Get an array containing information about registered shortcodes
clear()
Remove all registered shortcodes.
mixed
callShortcode(string $tag, array $attributes, string $content, array $extra = array())
Call a shortcode and return its replacement text Returns false if the shortcode isn't registered
bool|mixed|string
getShortcodeReplacementText(array $tag, array $extra = array(), bool $isHTMLAllowed = true)
Return the text to insert in place of a shoprtcode.
Behaviour in the case of missing shortcodes depends on the setting of ShortcodeParser::$error_behavior.
array
extractTags(string $content)
Look through a string that contains shortcode tags and pull out the locations and details of those tags
Doesn't support nested shortcode tags
string
parse(string $content)
Parse a string, and replace any registered shortcodes within it with the result of the mapped callback.
