So trying to get familiar with the theme I am using for my personal blog, theme is here:[https://github.com/xVicissitudex/WordPress-Themes/blob/main/unblock/index.php])
In index.php, what is the purpose of do\_action()? WordPress is [saying]) that the function requires one argument at least which is the hook name. WordPress will then call the callback function attached to said hook. Looking at the function though, `unblock_blog_home_heading` cannot be a standard wordpress hook, so is it custom? I am trying to find the definition in the theme but cannot do it. Is there anyway I can do a search for the definition?
get_header(); ?>
<?php // Action hook for the blog home page heading area
do_action(‘unblock_blog_home_heading’);
// Action hook for any content placed before posts
do_action(‘unblock_before_posts’);
// Get our blog layout
unblock_blog_styles();
// Action hook for any content placed after posts
do_action(‘unblock_after_posts’);
?>
<?php
get_footer();
