WYSIWYG component

The WYSIWYG component is an adapter for TinyMCE that integrates an editor instance with the form component. It expects a complete widget declaration in the content option, which should contain both markup and the script responsible for creating the editor's instance.

The application supports all selector, plugin, and toolbar/menu configuration options supported by the TinyMCE tinymce.init() method. However, the application doesn't validate TinyMCE configuration options or flag invalid values before adding the editor to a page.

Options

Extends all abstract configuration.

Wysiwyg-specific options:

OptionDescriptionTypeDefault
class
The path to the component class.
Object
Magento\Ui\Component\Form\Element\Wysiwyg
component
The path to the component’s .js file in terms of RequireJS.
String
'Magento_Ui/js/form/element/wysiwyg'
content
Initial WYSIWYG content.
String
''
elementSelector
The selector of the HTML element that is wrapped by the WYSIWYG editor.
String
'textarea'
elementTmpl
The path to the template particular field type template, specific for this component.
String
'ui/form/element/wysiwyg'
links.value
Links the component's value property with the provider, using the path that is declared in the dataScope property.
String
'${ $.provider }:${ $.dataScope }'
template
The path to the general Field template.
String
'ui/form/field'

Events

Events are dispatched by modules when certain actions are triggered. When an event is dispatched, it can pass data to any observers configured to watch that event.

Use a global varienGlobalEvents to attach a custom event handler to WYSIWYG events. For example:

Copied to your clipboard
require([
    'mage/adminhtml/events'
], function () {
    /**
     * Editor focused.
     */
    function editorFocused() {
        console.log('The editor is focused!');
    }


    varienGlobalEvents.attachEventHandler('tinymceFocus', editorFocused);
});

The following are available events for use in the WYSIWYG component adapter for TinyMCE:

  • tinymceBeforeSetContent - fires before the contents are inserted into the editor
  • tinymcePaste - fires when a paste is done within the editor
  • tinymceSaveContent - fires when the contents in the editor are saved
  • tinymceSaveContent (PostProcess) - fires when the contents in the editor are being serialized
  • tinymceUndo - fires when the contents have been reverted to a previous state
  • tinymceFocus - fires when the editor is focused
  • tinymceBlur - fires when the editor is blurred
  • tinymceChange - fires when undo level is added to the editor
  • wysiwygEditorInitialized - fires when the WYSIWYG editor is initialized

Add a default editor

Adding the default WYSIWYG editor to a page requires the following steps:

  1. Create a layout
  2. Create a form
  3. Add a data provider, controller, and routes

The following example shows how to integrate the default WYSIWYG editor as a UI component inside a custom form.

First, create a layout file in the ModuleName\view\adminhtml\layout directory and register the UI component:

ModuleName\view\adminhtml\layout\wysiwyg_on_custom_page.xml

Copied to your clipboard
<?xml version="1.0"?>
<!--
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
-->
<page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
    <body>
        <referenceContainer name="content">
            <uiComponent name="wysiwyg_on_custom_page"/>
        </referenceContainer>
    </body>
</page>

Next, create a custom form in the ModuleName\view\adminhtml\ui_component directory:

ModuleName\view\adminhtml\ui_component\wysiwyg_custom_form.xml

Copied to your clipboard
<?xml version="1.0"?>
<!--
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
-->
<form xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:module:Magento_Ui:etc/ui_configuration.xsd">
    <fieldset name="content">
        <settings>
            <label>Wysiwyg Content</label>
        </settings>
        <field name="wysiwyg_example" sortOrder="50" formElement="wysiwyg">
            <argument name="data" xsi:type="array">
                <item name="config" xsi:type="array">
                    <item name="wysiwygConfigData" xsi:type="array">
                        <item name="height" xsi:type="string">100px</item>
                        <item name="add_variables" xsi:type="boolean">true</item>
                        <item name="add_widgets" xsi:type="boolean">true</item>
                        <item name="add_images" xsi:type="boolean">true</item>
                        <item name="add_directives" xsi:type="boolean">true</item>
                    </item>
                </item>
            </argument>
            <settings>
                <label>Content</label>
            </settings>
            <formElements>
                <wysiwyg>
                    <settings>
                        <rows>8</rows>
                        <wysiwyg>true</wysiwyg>
                    </settings>
                </wysiwyg>
            </formElements>
        </field>
    </fieldset>
</form>

Last, add your data provider, controller, and routes. Refer to Creating an Admin page for more information.

Modify the default editor

The most common way to configure UI components in the application is to add a configuration section inside the XMl element when declaring it on a form. If you need to apply dynamic modifications to a UI component, we recommend using PHP modifiers since the application supports replacing the default WYSIWYG editor with other WYSIWYG libraries.

To use PHP modifiers, your data provider must inherit from ModifierPoolDataProvider. The following class adds support for modifier pools, which are required when using modifiers. Inheriting from this class allows you to use modifiers.

Magento\Ui\DataProvider\ModifierPoolDataProvider

Copied to your clipboard
<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Magento\Ui\DataProvider;


use Magento\Framework\App\ObjectManager;
use Magento\Ui\DataProvider\Modifier\ModifierInterface;
use Magento\Ui\DataProvider\Modifier\Pool;
use Magento\Ui\DataProvider\Modifier\PoolInterface;


class ModifierPoolDataProvider extends AbstractDataProvider
{
    /**
     * @var PoolInterface
     */
    private $pool;


    /**
     * @param string $name
     * @param string $primaryFieldName
     * @param string $requestFieldName
     * @param PoolInterface|null $pool
     * @param array $meta
     * @param array $data
     */
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        array $meta = [],
        array $data = [],
        PoolInterface $pool = null
    ) {
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data);
        $this->pool = $pool ?: ObjectManager::getInstance()->get(PoolInterface::class);
    }


    /**
     * {@inheritdoc}
     */
    public function getData()
    {
        $this->getConfigData();


        foreach ($this->pool->getModifiersInstances() as $modifier) {
            $this->data = $modifier->modifyData($this->data);
        }


        return $this->data;
    }


    /**
     * {@inheritdoc}
     */
    public function getMeta()
    {
        $this->meta = parent::getMeta();


        /** @var ModifierInterface $modifier */
        $this->pool->getModifiers();


        foreach ($this->pool->getModifiersInstances() as $modifier) {
            $this->meta = $modifier->modifyMeta($this->meta);
        }


        return $this->meta;
    }
}

Your form must then use a data provider that inherits from ModifierPoolDataProvider. For example:

Test\Module\Model\DataProvider

Copied to your clipboard
<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Test\Module\Model;


use Magento\Ui\DataProvider\Modifier\PoolInterface;
use Test\Module\Model\ResourceModel\WysiwygContent\CollectionFactory;


/**
 * Class DataProvider
 */
class DataProvider extends \Magento\Ui\DataProvider\ModifierPoolDataProvider
{
    public function __construct(
        $name,
        $primaryFieldName,
        $requestFieldName,
        CollectionFactory $collectionFactory,
        array $meta = [],
        array $data = [],
        PoolInterface $pool = null
    ) {
        parent::__construct($name, $primaryFieldName, $requestFieldName, $meta, $data, $pool);
        $this->collection = $collectionFactory->create();
    }
}

After you configure the modifier pool in your data provider, you must create the modifier. This is the code that changes the default configuration defined in Magento\Cms\Model\Wysiwyg\Config.php. Modifier values override the default configuration, so they allow you to change default behavior.

The following example shows how to change the default WYSIWYG editor toolbar and plugins configuration:

Test\Module\Ui\DataProvider\Custom\Modifier\WysiwygConfigModifier

Copied to your clipboard
<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */
namespace Test\Module\Ui\DataProvider\Custom\Modifier;


use Magento\Ui\DataProvider\Modifier\ModifierInterface;
use Magento\Ui\DataProvider\Modifier\WysiwygModifierInterface;


/**
 * Class WysiwygConfigModifier
 *
 * @api
 *
 * @SuppressWarnings(PHPMD.NumberOfChildren)
 * @since 101.0.0
 */
class WysiwygConfigModifier implements ModifierInterface
{
    /**
     * @param array $data
     * @return array
     * @since 100.1.0
     */
    public function modifyData(array $data)
    {
        return $data;
    }


    /**
     * @param array $meta
     * @return array
     * @since 100.1.0
     */
    public function modifyMeta(array $meta)
    {
        $meta['content']['children']['custom_wysiwyg_on_custom_page']['arguments']['data']['config']['wysiwygConfigData']['tinymce']['toolbar'] = 'bold italic underline | alignleft aligncenter alignright | code';
        $meta['content']['children']['custom_wysiwyg_on_custom_page']['arguments']['data']['config']['wysiwygConfigData']['tinymce']['plugins'] = 'advlist autolink lists link image charmap media table contextmenu paste code help table';
        return $meta;
    }
}

The last thing you need to do is configure the data provider's pool and connect the pool to your modifier. This is done through dependency injection, so you need to add a di.xml file to your project at ModuleName\etc\adminhtml\di.xml.

Here's an example that connects the data provider and modifier created in the previous steps:

Test\Module\etc\adminhtml\di.xml
