One of my clients has a website using Advanced Custom Fields (ACF) Blocks to style everything in the site, including their News section.

To make a new post in News, they had to load a Pattern of the relevant Blocks. This being a multi-step process, and a bit annoying if you just want to get on with posting your article, I looked for a way to load the blocks into the new post by default.

You can do this by putting this code in your functions.php (with amends explained below)

function site_post_register_template() {
    $post_type_object = get_post_type_object( 'post' );
    $post_type_object->template = array(
        array( 'my-blocks/news-header' ),
        array( 'my-blocks/news-article' ),
        array( 'my-blocks/news-article-related' ),
    );
}
add_action( 'init', 'site_post_register_template' );

In this case, I have three Blocks loading – the specific header, the article, and a strip of related articles. I can load in as many Blocks as I want.

To make this work for you, find where you have saved your blocks and list them out in the same way, in an array for each.

You will have to change ‘my-blocks’ to the prefix of your ACF Blocks. To find that prefix, go to the directory where you store the code for the relevant Block and open the block.json file. Copy the details from the “name” line to be inside the array( '' ), above.

Now, when a new Post is started, it automatically loads in the ACF Blocks and my client can get on with posting their news, not thinking about how they load in the Pattern and where they left my instructions for doing so.
