Enable the Classic Editor in WordPress

ByMuhammad Imanudin Posted on

This tutorial will guide you on how to use the provided code snippet to enable the Classic Editor for specific post types in WordPress. You can use this code as a standalone plugin or add it to FluentSnippets.

Introduction

This code selectively disables the Gutenberg (Block) Editor for specified post types and reverts to the Classic Editor for those post types. This is useful if you prefer using the Classic Editor for certain content types while using the Block Editor for others.

// Function to selectively disable the Gutenberg editor for specified post types
function custom_classic_editor_for_post_types($use_block_editor, $post) {
    // Array of post types to use the Classic Editor
    $classic_editor_post_types = array('page', 'custom_post_type'); // Add your custom post types here

    // Check if the current post type is in the array
    if (in_array($post->post_type, $classic_editor_post_types)) {
        // Disable the Gutenberg editor
        return false;
    }

    // Use the Block Editor for other post types

Understanding the Code

  • Plugin Header: Provides metadata about the plugin.
  • Function custom_classic_editor_for_post_types:
  • Parameters:
    • $use_block_editor: A boolean indicating whether the Block Editor is used.
    • $post: The post object.
  • Logic:
    • Checks if the current post type is in the $classic_editor_post_types array.
    • If yes, returns false to disable the Block Editor.
    • Otherwise, returns the original $use_block_editor value.

Configuration and Customization

  • Post Types: Ensure you replace 'custom_post_type' with your actual custom post type names.
  • Testing: After activation, create or edit posts of the specified types to ensure the Classic Editor is enabled.

Troubleshooting

  • Misspelled Post Types: Double-check the post type names for accuracy.
  • Compatibility: Verify that the code works with your version of WordPress.
