ckeditor5-symfony

CKEditor 5 for Symfony >=6.4.x — a lightweight WYSIWYG editor integration for Symfony. Easy to set up, it supports custom builds, dynamic loading, and localization. The package includes JavaScript and CSS assets, making it simple to integrate CKEditor 5 into your Symfony applications.

Important

This integration is unofficial and not maintained by CKSource. For official CKEditor 5 documentation, visit ckeditor.com. If you encounter any issues in editor, please report them on the GitHub repository.

Installation 🚀

Install the package:

composer require mati365/ckeditor5-symfony

Enable the bundle:

// config/bundles.php

return [
  // ...
  Mati365\CKEditor5Symfony\CKEditorBundle::class => ['all' => true],
];

Run the installer:

Choose the distribution method that best fits your needs:

🏠 Self-hosted (Recommended) Bundles assets locally. No Node.js required.
```
php bin/console ckeditor5:assets-mapper:install
```
📡 CDN Distribution Loads assets from CKSource CDN.
```
php bin/console ckeditor5:assets-mapper:install --distribution=cloud
```
For CDN, add CKEDITOR5_LICENSE_KEY="your-key" to your .env file.

💡 Tip: Add --premium to either command to install premium features (requires a valid license).

For more options, see Installer command options.

Usage 📖

To use CKEditor 5 in your Twig templates, simply call the cke5_editor() function:

{{ cke5_editor('Your content here') }}

If you don't use AssetsMapper, and your distribution is set to cloud, make sure to include the assets using cke5_cloud_assets() in your <head> section.

{{ cke5_cloud_assets() }}

This will render a classic editor with the provided content. For more advanced usage, check the playground examples.

Basic Usage 🏁

Get started with the most common usage patterns. These examples show how to render editors in your templates.

Simple Editor ✏️

Create a basic editor with default toolbar and features.

{{ cke5_editor(
  content: '<p>Initial content</p>',
  editorType: 'classic',
  editableHeight: 300
) }}

Watchdog prop 🐶

By default, the editor uses a built-in watchdog mechanism to automatically restart the editor if it crashes (e.g., due to a JavaScript error). The watchdog periodically saves the editor's content and restores it after a crash, minimizing the risk of data loss for users.

Disabling the watchdog 🚫

The watchdog is enabled by default. To disable it, set the watchdog argument to false:

{{ cke5_editor(
  content: '<p>Initial content</p>',
  editorType: 'classic',
  watchdog: false
) }}

Editor Types 🖊️

CKEditor 5 Symfony supports four distinct editor types, each designed for specific use cases. Choose the one that best fits your application's layout and functionality requirements.

Classic editor 📝

Traditional WYSIWYG editor with a fixed toolbar above the editing area. Best for standard content editing scenarios like blog posts, articles, or forms.

{{ cke5_editor(
  content: '<p>Initial content here</p>',
  editorType: 'classic',
  editableHeight: 300
) }}

Multiroot editor 🌳

Advanced editor supporting multiple independent editable areas within a single editor instance. Perfect for complex layouts like page builders, newsletters, or multi-section content management.

{# Editor container #}
{{ cke5_editor(editorType: 'multiroot') }}

{# Shared toolbar #}
{{ cke5_ui_part('toolbar') }}

{# Multiple editable areas #}
<div class="row">
  <div class="col">
    <h2>Header</h2>
    {{ cke5_editable(rootName: 'header', content: 'Header content', class: 'border') }}
  </div>
  <div class="col">
    <h2>Content</h2>
    {{ cke5_editable(rootName: 'content', content: 'Main content', class: 'border') }}
  </div>
</div>

Inline editor 📝

Minimalist editor that appears directly within content when clicked. Ideal for in-place editing scenarios where the editing interface should be invisible until needed.

{{ cke5_editor(
  content: '<p>Click here to edit this content</p>',
  editorType: 'inline',
  editableHeight: 300
) }}

Note: Inline editors don't work with <textarea> elements and may not be suitable for traditional form scenarios.

Decoupled editor 🌐

Flexible editor where toolbar and editing area are completely separated. Provides maximum layout control for custom interfaces and complex applications.

{# Decoupled editor container #}
{{ cke5_editor(id: 'decoupled-editor', editorType: 'decoupled') }}

<div class="editor-container">
  {# Toolbar can be placed anywhere #}
  {{ cke5_ui_part('toolbar') }}

  {# Editable area with custom styling #}
  {{ cke5_editable(
    content: '<p>Initial content here</p>',
    class: 'border p-4 rounded',
    editableHeight: 300
  ) }}
</div>

Forms Integration 🧾

Seamlessly integrate CKEditor 5 with Symfony Forms. The bundle provides a CKEditor5Type that facilitates easy integration.

Symfony Form Type 🧑‍💻

Use CKEditor5Type in your form class to render the editor.

use Mati365\CKEditor5Symfony\Form\Type\CKEditor5Type;
// ...

$builder->add('content', CKEditor5Type::class, [
  'label' => 'Article Content',
  'required' => true,
  'attr' => ['row_attr' => ['class' => 'text-editor']],
]);

Then in your template:

{{ form_row(form.content) }}

The editor automatically synchronizes its content with the underlying hidden input field upon form submission.

Configuration ⚙️

You can configure the editor presets in your config/packages/ckeditor5.yaml file. The default preset is default, which provides a basic configuration with a toolbar and essential plugins. The preset is a map that contains the editor configuration, including the toolbar items and plugins. There can be multiple presets, and you can switch between them by passing the preset keyword argument to the cke5_editor function.

Custom Presets 🧩

In order to override the default preset or add custom presets, you can add the following configuration:

# config/packages/ckeditor5.yaml

ckeditor5:
  presets:
    minimal:
      editorType: classic
      config:
        toolbar: [bold, italic, link]
        plugins: [Bold, Italic, Link, Essentials, Paragraph]

      # Only if don't use AssetsMapper and using cloud distribution. Otherwise, this section is
      # automatically configured during `ckeditor5:assets-mapper:install` command.
      cloud:
        version: 46.0.0
        premium: true
        translations: [pl]
        ckbox:
          version: 1.0.0

    full:
      editorType: classic
      config:
        toolbar:
          - heading
          - '|'
          - bold
          - italic
          - underline
          - '|'
          - link
          - insertImage
          - insertTable
          - '|'
          - bulletedList
          - numberedList
          - blockQuote
        plugins:
          - Heading
          - Bold
          - Italic
          - Underline
          - Link
          - ImageBlock
          - ImageUpload
          - Table
          - List
          - BlockQuote
          - Essentials
          - Paragraph

In template:

{{ cke5_editor(content: '<p>Simple editor</p>', preset: 'minimal') }}

The default one is specified here src/DependencyInjection/DefaultConfiguration.php.

Dynamic configuration 🎯

You can also override configuration at runtime by passing config or mergeConfig arguments to the editor function. This is useful if you want to change the editor configuration based on user input or other conditions.

{# Override configuration (shallow merge) #}
{{ cke5_editor(
    content: 'Content',
    config: { 'toolbar': ['bold', 'italic'] }
) }}

{# Merge configuration (deep merge) #}
{{ cke5_editor(
    content: 'Content',
    mergeConfig: { 'toolbar': { 'items': ['bold'] } }
) }}

Providing the License Key 🗝️

CKEditor 5 requires a license key when using the official CDN or premium features. You can provide the license key in two simple ways:

Environment variable: Set the CKEDITOR5_LICENSE_KEY environment variable in your .env file. This is the easiest and most common way.
Preset config: You can also set the license key directly in your preset configuration in config/packages/ckeditor5.yaml:
```
ckeditor5:
  presets:
    custom:
      # ...
      licenseKey: your-license-key-here
```

If you use CKEditor 5 under the GPL license, you do not need to provide a license key. However, if you choose to set one, it must be set to GPL.

If both are set, the preset config takes priority. For more details, see the CKEditor 5 licensing guide.

Referencing DOM Elements in Config 🏷️

You can reference DOM elements directly in your editor configuration using the special { $element: "selector" } format. This is useful when you want to attach the editor's UI parts (like toolbars or editable areas) to specific elements in your HTML.

How to use 🛠️

In your config object, use { "$element": "CSS_SELECTOR" } wherever a DOM element is expected.
The selector will be resolved to the actual DOM element before initializing the editor.

Example 📄

# config/packages/ckeditor5.yaml

ckeditor5:
  presets:
    # ... other presets
    minimal:
      config:
        # ... other config
        yourPlugin:
          toolbar: {$element: '#my-toolbar'}
          editable: {$element: '#my-editable'}

This will find the elements with IDs my-toolbar and my-editable in the DOM and use them for the editor's UI.

⚠️ If the element is not found, a warning will be shown in the console.

Localization 🌍

Support multiple languages in the editor UI and content. Learn how to load translations via CDN or configure them globally.

CDN Translation Loading 🌐

Depending on your setup, you can preload translations via CDN.

AssetsMapper local translations assignment 📦

If you want to load a specific language for the editor UI, you can specify the language argument in the cke5_editor() function:

{{ cke5_editor(
    language: 'pl',
    content: '<p>Content in English, UI in Polish</p>'
) }}

Remember, that this only works if you have installed the translations using the ckeditor5:assets-mapper:install command with the --translations option.

php bin/console ckeditor5:assets-mapper:install --translations=pl,de,fr

Global CDN translation loading ☁️

If you don't use AssetsMapper, you can load translations directly from CDN by specifying them in the preset config or during installation. See Global Translation Config for more details.

If you want to specify it in the template,you can use cke5_cloud_assets() function:

{# It'll load translations for Polish, German, and French from CDN #}
{{ cke5_cloud_assets(translations: ['pl', 'de', 'fr']) }}

Global Translation Config 🛠️

AssetsMapper translations installation 📥

You can fetch translations globally by specifying them in the ckeditor5:assets-mapper:install command:

php bin/console ckeditor5:assets-mapper:install --translations=pl,de,fr

Direct CDN translations configuration ⚙️

You can also configure translations globally in your configuration file. This is useful if you want to load translations for multiple languages at once or set a default language for the editor. Keep in mind that this configuration is only used when loading translations via CDN. If you are using self-hosted setup, translations are handled by your bundler automatically.

# config/packages/ckeditor5.yaml

ckeditor5:
  presets:
    custom:
      cloud:
        translations: [pl, de, fr]

Note: For self-hosted setups, translations are handled by your bundler automatically.

Custom translations 🌐

You can also provide custom translations for the editor. This is useful if you want to override existing translations or add new ones. Custom translations can be provided in the preset configuration.

# config/packages/ckeditor5.yaml

ckeditor5:
  presets:
    custom:
      # ...
      customTranslations:
        en:
          Bold: Custom Bold
          Italic: Custom Italic
        pl:
          Bold: Pogrubiony
          Italic: Kursywa

Custom plugins 🧩

To register a custom plugin, use the CustomEditorPluginsRegistry.

import { CustomEditorPluginsRegistry as Registry } from '@mati365/ckeditor5-symfony';

const unregister = Registry.the.register('MyCustomPlugin', async () => {
  // It's recommended to use lazy import to
  // avoid bundling ckeditor code in your application bundle.
  const { Plugin } = await import('ckeditor5');

  return class extends Plugin {
    static get pluginName() {
      return 'MyCustomPlugin';
    }

    init() {
      console.log('MyCustomPlugin initialized');
      // Custom plugin logic here
    }
  };
});

In order to use the plugin you need to extend your config in config/packages/ckeditor5.yaml:

ckeditor5:
  presets:
    custom:
      config:
        plugins: [MyCustomPlugin, Essentials, Paragraph]
        # ... other config options

It must be called before the editor is initialized. You can unregister the plugin later by calling the returned function:

unregister();
// or CustomEditorPluginsRegistry.the.unregister('MyCustomPlugin');

If you want to de-register all registered plugins, you can use the unregisterAll method:

import { CustomEditorPluginsRegistry } from '@mati365/ckeditor5-symfony';

CustomEditorPluginsRegistry.the.unregisterAll();

Context 🤝

The context feature is designed to group multiple editor instances together, allowing them to share a common context. This is particularly useful in collaborative editing scenarios, where users can work together in real time. By sharing a context, editors can synchronize features such as comments, track changes, and presence indicators across different editor instances. This enables seamless collaboration and advanced workflows in your application.

For more information about the context feature, see the CKEditor 5 Context documentation.

Basic usage 🔧

Define your context in configuration:

ckeditor5:
  contexts:
    your_context:
      config:
        plugins:
          - CustomContextPlugin
      watchdogConfig:
        crashNumberLimit: 20

And use it in your template:

{# Initialize context #}
{{ cke5_context(id: 'shared-context', contextPreset: 'your_context') }}

{# Connect editors to context #}
{{ cke5_editor(content: 'Child A', contextId: 'shared-context') }}
{{ cke5_editor(content: 'Child B', contextId: 'shared-context') }}

Voila!

Custom context translations 🌐

Define your custom translations in the configuration:

ckeditor5:
  contexts:
    custom:
      # ...
      customTranslations:
        en:
          Bold: Custom Bold
          Italic: Custom Italic
        pl:
          Bold: Pogrubiony
          Italic: Kursywa

These translations will be used in the context's editors, overriding the default translations. They are available through locale.t plugin in every context plugin.

Watch registered editors 👀

You can watch the registered editors using the watch function. This is useful if you want to react to changes in the registered editors, for example, to update the UI or perform some actions when an editor is added or removed.

import { EditorsRegistry } from '@mati365/ckeditor5-symfony';

const unregisterWatcher = EditorsRegistry.the.watch((editors) => {
  console.log('Registered editors changed:', editors);
});

// Later, you can unregister the watcher
unregisterWatcher();

Wait for particular editor to be registered ⏳

You can also wait for a specific editor to be registered using the waitForEditor function. This is useful if you want to perform some actions after a specific editor is registered.

This method can be called before the editor is initialized, and it will resolve when the editor is registered.

import { EditorsRegistry } from '@mati365/ckeditor5-symfony';

EditorsRegistry.the.waitFor('editor1').then((editor) => {
  console.log('Editor "editor1" is registered:', editor);
});

// ... init editor somewhere later

The id of the editor must be used to identify the editor. If the editor is already registered, the promise will resolve immediately.
