Take Control of Your WordPress Editor: Understanding the `wp_default_editor` Filter Hook

When you’re crafting content in WordPress, you’re likely familiar with the two editor modes: the visual editor (often powered by TinyMCE) and the text editor (which allows you to work directly with HTML). By default, WordPress chooses one of these as the initial view when you create a new post or page. But did you know you can easily customize this default behavior?

Enter the wp_default_editor filter hook – a powerful tool that allows you to programmatically set your preferred default editor mode. In this guide, we’ll explore what this hook is, why you might want to use it, and how to implement it on your WordPress website.

Understanding the WordPress Editor

Before we dive into the technical details, let’s briefly recap the two main editor modes in WordPress:

• Visual Editor (TinyMCE): This is a WYSIWYG (“What You See Is What You Get”) editor that allows you to format your content using a familiar toolbar, similar to word processing software. It’s ideal for users who prefer a more intuitive and visual approach to content creation.
• Text Editor (HTML): This editor displays the raw HTML code of your content. It’s preferred by users who are comfortable working directly with markup and need more granular control over the structure and presentation of their posts and pages.

Introducing the wp_default_editor Filter Hook

In WordPress, filter hooks allow you to modify data before it’s used. The wp_default_editor hook is specifically designed to let you change the default editor mode that WordPress loads when a user starts writing a new post or page.

By using this hook, you can ensure that your preferred editor mode is always the first one you see, streamlining your content creation workflow.

Why Would You Want to Change the Default Editor?

There are several reasons why you might want to customize the default editor in WordPress:

• Personal Preference: If you consistently prefer working in the HTML editor for its direct control, setting it as the default can save you a click every time you start a new post.
• Specific User Roles: If your website has users with specific roles who primarily work with code, you might want to set the default editor to ‘html’ for them.
• Consistency: For websites where content creators follow a strict HTML structure, forcing the default to the text editor can encourage this practice.
• Troubleshooting: In some cases, you might want to temporarily switch the default editor for testing or debugging purposes.

How to Use the wp_default_editor Filter Hook

The provided PHP code snippet demonstrates how to use the wp_default_editor filter hook:

/**
 * Set default editor mode to 'html' or 'tinymce'
 *
 */
add_filter('wp_default_editor',
    function () {
        return 'html';
    }
);

Let’s break down this code:

• add_filter('wp_default_editor', ...);: This function is used to register a new filter.
  • 'wp_default_editor' is the name of the filter hook we want to use.
  • The second argument is a callback function that will be executed when this filter is applied.
• function () { ... }: This is an anonymous function (a function without a name) that will be executed.

• return 'html';: Inside the function, we are returning the string 'html'. This tells WordPress to set the default editor mode to the Text (HTML) editor.

How to Implement This Code:

You can add this code to your WordPress website in a couple of ways:

1. Using Your Theme’s functions.php File (Not Recommended for Beginners):
   • Navigate to Appearance > Theme File Editor in your WordPress dashboard.
   • Locate and select the functions.php file for your current theme.
   • Carefully scroll to the bottom of the file and paste the code before the closing ?> tag (if it exists).
   • Click Update File.

   Important Note: Directly editing your theme’s functions.php file can be risky. If you make a mistake, it could break your website. It’s always recommended to use a child theme for customizations or, even better, a code snippet plugin.

2. Using a Code Snippet Plugin (Recommended):

   • Install and activate a code snippet plugin like WPCode (formerly Insert Headers and Footers + Custom Code Snippets) or Code Snippets.
   • Go to the plugin’s interface (usually under a “Snippets” or “Code Snippets” menu in your WordPress dashboard).
   • Click on Add New Snippet.
   • Give your snippet a descriptive title (e.g., “Set Default Editor to HTML”).
   • In the code area, paste the provided PHP code.
   • Ensure the snippet is set to run globally on your website.
   • Click Save Changes and then Activate.

Setting the Default to the Visual Editor (‘tinymce’):

If you prefer to set the default editor to the Visual editor, simply change the return value in the code to 'tinymce':

add_filter('wp_default_editor',
    function () {
        return 'tinymce';
    }
);

Follow the same steps above to implement this code snippet.

Important Considerations

• Global Change: Implementing this code will change the default editor for all users on your WordPress website.
• User Override: While you’re setting the default, individual users can still change their preferred editor mode within the post/page editor interface after the page loads. This hook only controls the initial view.
• User Profile Settings: WordPress also allows individual users to set their preferred editor mode in their user profile settings (under Users > Your Profile). This setting will override the default set by the wp_default_editor hook for that specific user.

Conclusion: Tailoring Your WordPress Editing Experience

The wp_default_editor filter hook provides a simple yet effective way to customize the initial editor mode in WordPress. Whether you prefer the direct control of HTML or the visual ease of TinyMCE, this hook allows you to tailor your content creation environment to your specific needs and workflow. By using a code snippet plugin, you can safely implement this customization without directly altering your theme files.

Key Takeaways:

• The wp_default_editor filter hook allows you to set the default editor mode in WordPress.
• You can set the default to either 'html' (Text editor) or 'tinymce' (Visual editor).
• Implement the code using your theme’s functions.php file (with caution) or a code snippet plugin (recommended).
• This change affects the default for all users, but individual users can still switch editors.
• Users can also set their preferred editor in their user profile.
