WordPress Main Blocks Functions Link
How Gutenberg overrides blocks from core & loads blocks: lib/blocks.php
Blocks API: WP_Block_Template class - added in 5.8
Mostly empty class except to define public variables that set things like id, title, content, description, source of template (user, theme, core)
The block template loader functions that add filters to use 'wp_template' posts instead of theme template files.
Adds the following tags to head:
- Adds viewport meta tag via
add_action( 'wp_head', _block_template_viewport_meta_tag', 0 ) - Renders the
<title>tag from post title (happens whether or not theme_support is enabled for title-tag).
Renders '<div class="wp-site-blocks">' . $content . '</div>' via get_the_block_template_html()
// Define constants for supported wp_template_part_area taxonomy.
if ( ! defined( 'WP_TEMPLATE_PART_AREA_HEADER' ) ) {
define( 'WP_TEMPLATE_PART_AREA_HEADER', 'header' );
}
if ( ! defined( 'WP_TEMPLATE_PART_AREA_FOOTER' ) ) {
define( 'WP_TEMPLATE_PART_AREA_FOOTER', 'footer' );
}
if ( ! defined( 'WP_TEMPLATE_PART_AREA_SIDEBAR' ) ) {
define( 'WP_TEMPLATE_PART_AREA_SIDEBAR', 'sidebar' );
}
if ( ! defined( 'WP_TEMPLATE_PART_AREA_UNCATEGORIZED' ) ) {
define( 'WP_TEMPLATE_PART_AREA_UNCATEGORIZED', 'uncategorized' );
}Default directories for templates and template parts in block themes are now: templates and parts although
get_block_theme_folders() adds backwards compatibility to render the old block-templates and block-template-parts folders as
template directories.
The Default templates loaded - these add a class of 'index', 'home', etc to the <body> tag.
