Introduction

Building a robust e-commerce platform using Magento 2 often demands a deep understanding of its extensive features and customization options. If you're a developer working with Magento 2, you might have encountered a situation where you need to add a WYSIWYG (What You See Is What You Get) editor to dynamic fields in the system configuration. This editor can greatly enhance the usability and appearance of text-based fields, offering a more visual way to create and edit content.

Although Magento 2 provides the framework to implement a WYSIWYG editor, the process can be tricky, with several potential pitfalls along the way. This blog post will walk you through the necessary steps to add a WYSIWYG editor to dynamic fields in Magento 2’s system configuration. By the end, you’ll have a clearer understanding and a practical solution for your next project.

Let's dive into the detailed process, understand the importance of each step, and ensure you can effectively add WYSIWYG editors to your dynamic fields.

Understanding WYSIWYG in Magento 2

What is a WYSIWYG Editor?

A WYSIWYG editor provides a user-friendly interface for editing text and media directly on the platform, displaying the content in a form closely resembling its appearance in the final product. This visual feedback can make the process more intuitive for users compared to text-based editing.

In Magento 2, the WYSIWYG editor streamlines the creation of rich-text content. It's especially useful for sections where users frequently update content, such as product descriptions, blog posts, and CMS pages.

Why Integrate a WYSIWYG Editor?

Integrating a WYSIWYG editor into the Magento 2 system configuration enhances user experience by providing an intuitive, visual way to manage content. This eliminates the need for knowledge of HTML or CSS, making website management more accessible for non-developers.

Adding WYSIWYG to Dynamic Fields

Step-by-Step Implementation

To successfully add a WYSIWYG editor to dynamic fields within Magento 2’s system configuration, follow these steps:

1. Updating the system.xml File

The first essential step is to update the system.xml file, which defines the system configuration fields. You'll need to specify the field type and ensure it is prepared to render a WYSIWYG editor.

Example system.xml Configuration:

<config>
    <system>
        <section id="custom_section">
            <group id="custom_group">
                <field id="custom_field" translate="label" type="textarea">
                    <label>Custom Field Label</label>
                    <backend_model>Magento\Config\Model\Config\Backend\Serialized\ArraySerialized</backend_model>
                    <frontend_model>Vendor\Module\Block\Adminhtml\System\Config\Form\Field\Wysiwyg</frontend_model>
                </field>
            </group>
        </section>
    </system>
</config>

2. Creating the Custom Block

To render the WYSIWYG editor, create a custom block that extends the Magento 2 form field class. This block will initialize the WYSIWYG editor and ensure it displays correctly.

Example Custom Block:

<?php

namespace Vendor\Module\Block\Adminhtml\System\Config\Form\Field;

use Magento\Framework\Data\Form\Element\AbstractElement;
use Magento\Backend\Block\Widget\Form\Renderer\Fieldset as FieldsetRenderer;

class Wysiwyg extends FieldsetRenderer
{
    protected $_wysiwygConfig;

    public function __construct(
        \Magento\Backend\Block\Context $context,
        \Magento\Cms\Model\Wysiwyg\Config $wysiwygConfig,
        array $data = []
    ) {
        $this->_wysiwygConfig = $wysiwygConfig;
        parent::__construct($context, $data);
    }

    public function render(AbstractElement $element)
    {
        $element->setWysiwyg(true);
        $element->setConfig($this->_wysiwygConfig->getConfig());
        return parent::render($element);
    }
}

This code snippet demonstrates the custom block class that prepares the WYSIWYG editor's configuration and sets it up to render in the system configuration.

3. Adding JavaScript Dependencies

Magento 2 requires specific JavaScript components to render the WYSIWYG editor. Ensure these dependencies are loaded within the admin panel.

Example requirejs-config.js:

var config = {
    map: {
        '*': {
            wysiwygSetup: 'mage/adminhtml/wysiwyg/tiny_mce/setup'
        }
    }
};

4. Creating the Template

You may need a custom template to initialize and render the WYSIWYG editor within your custom block. Place this template file in the appropriate location and reference it from your custom block.

Example Template:

<div class="admin__field">
    <label class="label" for="{$elementId}">
        <span>{$elementLabel}</span>
    </label>
    <div class="value">
        {$elementHtml}
    </div>
</div>
<script>
    require(['wysiwygSetup'], function (wysiwygSetup) {
        wysiwygSetup({
            settings: {$wysiwygConfig}
        });
    });
</script>

5. Clearing Cache and Testing

After making these changes, clear the Magento cache to ensure the updates are loaded correctly. Navigate to the system configuration section in the admin panel to test if the WYSIWYG editor appears for your dynamic field.

Conclusion

Integrating a WYSIWYG editor into Magento 2's system configuration fields can considerably improve usability and accessibility for content managers. This process involves defining the configuration in system.xml, creating a custom block class to initialize the editor, and setting up the necessary JavaScript dependencies. By following these detailed steps, you can leverage the power of WYSIWYG editors to enrich dynamic fields in your Magento 2 application.

FAQ

How do I troubleshoot if the WYSIWYG editor does not appear?

Ensure that you have correctly configured the system.xml file and custom block. Also, verify that the required JavaScript files are loading without errors. Checking your browser console for any JavaScript errors can help identify issues.

Can this method be applied to other fields apart from textareas?

Yes, the same methodology can be adapted to other field types such as text fields or even custom elements. The key is to adjust the custom block and the WYSIWYG configuration appropriately.

Is it possible to use different WYSIWYG editors?

While Magento 2 primarily integrates TinyMCE as the default WYSIWYG editor, you can implement other editors by customizing the JavaScript setup and configuration in the custom block.

By enhancing your Magento 2 setup with WYSIWYG editors in system configurations, you provide a superior, user-friendly experience, simplifying the content management process and making it accessible to a broader range of users.
