New Post Type template using blockeditor

先读这个 Post Type – 笔记

To enable the block editor (Gutenberg) for your custom post type “book” (or whatever your post type is), you need to modify the register_post_type arguments within your functions.php file or custom plugin. Specifically, you need to add or modify the supports argument.

Here’s how you can do it:

1. Modify the supports Argument:

In your create_book_post_type() function (or the function where you register your custom post type), locate the supports array.

• If supports doesn’t exist, create it.
• If supports exists, add or ensure that 'editor' is included.

Here’s the modified code snippet:

PHP

function create_book_post_type() {
    // ... (Your labels and other args) ...

    $args = array(
        // ... (Your other arguments) ...
        'supports'            => array( 'title', 'editor', 'thumbnail', 'custom-fields' ), // Ensure 'editor' is present
        // ... (Your other arguments) ...
    );
    register_post_type( 'book', $args );
}
add_action( 'init', 'create_book_post_type', 0 );

Explanation:

• The 'editor' element within the supports array tells WordPress to enable the block editor for your custom post type.
• By default, if the 'editor' support is not declared, then WordPress will default to the classic editor.

2. Enable Template Support (Optional but Recommended):

If you want to use block templates (predefined block layouts) for your “book” post type, you can also add 'template' to the supports array:

PHP

$args = array(
    // ...
    'supports' => array( 'title', 'editor', 'thumbnail', 'custom-fields', 'template' ),
    // ...
);

3. Create Block Templates (Optional):

If you enabled template support, you can create block templates to define the initial content and layout for new “book” posts. Here’s how:

• Within your theme’s functions.php file or a custom plugin, use the register_block_template function.

PHP

function register_book_template() {
    $post_type_object = get_post_type_object( 'book' );
    $post_type_object->template = array(
        array( 'core/paragraph', array(
            'placeholder' => 'Enter book description here...',
        ) ),
        array( 'core/image', array(
            'align' => 'center',
        )),
        array( 'core/heading', array(
            'placeholder' => 'Additional Information',
            'level' => 3,
        )),
    );
}
add_action( 'init', 'register_book_template' );

• This code defines a template with a paragraph, an image, and a heading. When you create a new “book” post, these blocks will be pre-populated.

Important Notes:

• Clear Cache: After making changes to your functions.php file, clear your website’s cache (if you’re using a caching plugin) to ensure the changes take effect.
• Theme Compatibility: Ensure that your theme is compatible with the block editor. Most modern themes are, but older themes might have issues.
• Plugin Conflicts: If you encounter problems, try disabling other plugins to rule out conflicts.
• Custom Fields and the Block Editor: When working with custom fields, you might need to use plugins like Advanced Custom Fields (ACF) to integrate them seamlessly with the block editor.¹ ACF provides block types that allow you to display your custom field data within the block editor interface.²

By making these changes, you’ll successfully enable the block editor for your “book” custom post type, giving you the flexibility and power of Gutenberg for creating your book content.
