ProsemirrorRichText
extends AbstractRichText
in package
The ProsemirrorRichText is a [Prosemirror](https://prosemirror.net) and [Markdown-it](https://github.com/markdown-it/markdown-it) based rich text implementation.
This rich text is a pure markdown based rich text enhanced with some additional features and markdown plugins.
In order to stay compatible with the legacy rich text content, this rich text contains some pre-processing logic on the server side, which can be deactivated
if not required by means of the richtextCompatMode
setting of the content
module.
Note that this rich text, when in edit mode, just outputs an invisible div with pure markdown content, which will be interpreted by the related ProsemirrorRichTextEditor.
This rich text implementation supports all features as [[preset]], the [[includes]] and [[excludes]] of plugins and is extensible through additional javascript plugins.
Note that the plugin settings as [[preset]], [[includes]], [[excludes]], [[pluginOptions]] have to be set for the editor as well as for the rich text output widget.
Beside the default (GFM based) markdown-it syntax, the following plugins are available:
anchors
If enabled will add anchors to heading elements. This plugin is disabled by default and can be enabled as follows:
RichText::output($text, [
'preset' => 'myPreset',
'pluginOptions' => [
'anchors' => true
]
]);
// or with specific settings
RichText::output($text, [
'preset' => 'myPreset',
'pluginOptions' => [
'anchors' => ['permalink' => true]
]
]);
See markdown-it-anchor for more settings.
clipboard
Allows pasting of raw markdown content into the richtext editor.
emoji
twemoji and markdown-it-emoji based emojies
fullscreen
Adds a enlarge/shrink button to the rich text editor.
mention
Markdown link extension for mentionings in the form of
oembed
Enables scanning and replacement of pasted oembed links in form of link extensions
placeholder
Text placeholder for the editor input
strikethrough

Methods
__call()
Calls the named method which is not a class method.
public
__call(string $name, array<string|int, mixed> $params) : mixed
This method will check if any attached behavior has the named method and will execute it if available.
Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.
Parameters
- $name : string
-
the method name
- $params : array<string|int, mixed>
-
method parameters
Tags
Return values
mixed —the method return value
__clone()
This method is called after the object is created by cloning an existing one.
public
__clone() : mixed
It removes all behaviors because they are attached to the old object.
__construct()
Constructor.
public
__construct([array<string|int, mixed> $config = [] ]) : mixed
The default implementation does two things:
- Initializes the object with the given configuration
$config
. - Call [[init()]].
If this method is overridden in a child class, it is recommended that
- the last parameter of the constructor is a configuration array, like
$config
here. - call the parent implementation at the end of the constructor.
Parameters
- $config : array<string|int, mixed> = []
-
name-value pairs that will be used to initialize the object properties
__get()
Returns the value of a component property.
public
__get(string $name) : mixed
This method will check in the following order and act accordingly:
- a property defined by a getter: return the getter result
- a property of a behavior: return the behavior property value
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $value = $component->property;
.
Parameters
- $name : string
-
the property name
Tags
Return values
mixed —the property value or the value of a behavior's property
__isset()
Checks if a property is set, i.e. defined and not null.
public
__isset(string $name) : bool
This method will check in the following order and act accordingly:
- a property defined by a setter: return whether the property is set
- a property of a behavior: return whether the property is set
- return
false
for non existing properties
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($component->property)
.
Parameters
- $name : string
-
the property name or the event name
Tags
Return values
bool —whether the named property is set
__set()
Sets the value of a component property.
public
__set(string $name, mixed $value) : mixed
This method will check in the following order and act accordingly:
- a property defined by a setter: set the property value
- an event in the format of "on xyz": attach the handler to the event "xyz"
- a behavior in the format of "as xyz": attach the behavior named as "xyz"
- a property of a behavior: set the behavior property value
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing $component->property = $value;
.
Parameters

-
the property name or the event name
- $value : mixed
-
the property value
Tags
__unset()
Sets a component property to be null.
public
__unset(string $name) : mixed
This method will check in the following order and act accordingly:
- a property defined by a setter: set the property value to be null
- a property of a behavior: set the property value to be null
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($component->property)

afterRun()
This method is invoked right after a widget is executed.
public
afterRun(mixed $result) : mixed
The method will trigger the [[EVENT_AFTER_RUN]] event. The return value of the method will be used as the widget return value.
If you override this method, your code should look like the following:
public function afterRun($result)
{
$result = parent::afterRun($result);
// your custom code here
return $result;
}
Parameters
- $result : mixed
-
the widget return result.
Tags
Return values
mixed —the processed widget result.
attachBehavior()
Attaches a behavior to this component.
public
attachBehavior(string $name, string|array<string|int, mixed>|Behavior $behavior) : Behavior
This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the [[Behavior::attach()]] method.
Parameters
- $name : string
-
the name of the behavior.
- $behavior : string|array<string|int, mixed>|Behavior
-
the behavior configuration. This can be one of the following:
- a [[Behavior]] object
- a string specifying the behavior class
- an object configuration array that will be passed to [[Yii::createObject()]] to create the behavior object.
Tags
Return values
Behavior —the behavior object
attachBehaviors()
Attaches a list of behaviors to the component.
public
attachBehaviors(array<string|int, mixed> $behaviors) : mixed
Each behavior is indexed by its name and should be a [[Behavior]] object, a string specifying the behavior class, or an configuration array for creating the behavior.
Parameters
- $behaviors : array<string|int, mixed>
-
list of behaviors to be attached to the component
Tags
beforeRun()
This method is invoked right before the widget is executed.
public
beforeRun() : bool
The method will trigger the [[EVENT_BEFORE_RUN]] event. The return value of the method will determine whether the widget should continue to run.
When overriding this method, make sure you call the parent implementation like the following:
public function beforeRun()
{
if (!parent::beforeRun()) {
return false;
}
// your custom code here
return true; // or false to not run the widget
}
Tags
Return values
bool —whether the widget should continue to be executed.
begin()
Begins a widget.
public
static begin([array<string|int, mixed> $config = [] ]) : static
This method creates an instance of the calling class. It will apply the configuration to the created instance. A matching [[end()]] call should be called later. As some widgets may use output buffering, the [[end()]] call should be made in the same view to avoid breaking the nesting of output buffers.
Parameters
- $config : array<string|int, mixed> = []
-
name-value pairs that will be used to initialize the object properties
Tags
Return values
static —the newly created widget instance
behaviors()
Returns a list of behaviors that this component should behave as.
public
behaviors() : array<string|int, mixed>
Child classes may override this method to specify the behaviors they want to behave as.
The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:
'behaviorName' => [
'class' => 'BehaviorClass',
'property1' => 'value1',
'property2' => 'value2',
]
Note that a behavior class must extend from [[Behavior]]. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using [[getBehavior()]] or be detached using [[detachBehavior()]]. Anonymous behaviors can not be retrieved or detached.
Behaviors declared in this method will be attached to the component automatically (on demand).
Return values
array<string|int, mixed> —the behavior configurations.
