Block Theme Pattern Registration

    Hey guys, I’m building a child theme and trying to use the built in WP functionality to register my custom template-parts by placing them in the /patterns directory of my child theme.

    However, after doing this, the new patterns don’t display as options in the Site Editor UI or in Appearance / Editor / Patterns.

    The ONLY way I’ve been able to get them to register / display is by deactivating the child theme, switching to another theme, then reactivating the child theme. Once I did this, the patterns appear as expected.

    I couldn’t find any mention of it in the Theme Handbook -> https://developer.www.ads-software.com/themes/patterns/registering-patterns/

    Is this behaviour to be expected?

  • Hi Paul,

    Thanks for sharing the details about your issue. It sounds like the pattern registration is working, but the child theme isn’t triggering the pattern refresh immediately in the UI.

    This behavior is not typical and shouldn’t require theme switching to make the patterns appear. Here are a few things you could try:

    1. Clear cache: Sometimes WordPress or your browser may cache the theme files, causing changes not to appear immediately. Try clearing both WordPress and browser caches.
    2. Check theme.json file: Ensure your theme.json (if you have one) includes proper configuration for patterns, as it might influence their visibility in the editor.
    3. Use the register_block_pattern() function: If you’re comfortable with some PHP, you can manually register patterns using the register_block_pattern() function in your child theme’s functions.php. This ensures patterns are registered every time the theme is activated.
    register_block_pattern(
        'my-child-theme/my-pattern',
        array(
            'title'       => __( 'My Custom Pattern', 'my-child-theme' ),
            'description' => _x( 'A custom pattern for my theme', 'Block pattern description', 'my-child-theme' ),
            'content'     => '<!-- wp:group --> ... <!-- /wp:group -->',
        )
    );

    Theme switching workaround: If the theme switch is consistently working, it could indicate a loading or refresh issue within the child theme. Investigating further may help pinpoint if something in the theme files is delaying the registration.

    Hope this helps! Let me know if you need further clarification or assistance.

    Thanks Mohd Javed,

    I ended up setting the Development Mode to ‘theme’ in wp-config.php and that seems to have done the trick in busting the theme caching.

    define( ‘WP_DEVELOPMENT_MODE’, ‘theme’ );

    Regards
    Paul
