Hooks Reference

These are the action and filter hooks that KnowX defines in its own code. Use them from a child theme or plugin to extend the theme without editing its files. (WordPress core hooks and hooks from third-party plugins are not listed here.)

Action hooks

Action	Fired in	Purpose
`knowx_wp_body_open`	`inc/wordpress-shims.php` (runs on `wp_body_open`)	Right after the opening `<body>` tag. Add analytics or top-of-page markup.
`knowx_sub_header`	Page, single, archive, index, bbPress, and full-width templates	Renders the sub-header (breadcrumbs and search). Hook here to add content to the sub-header area.
`knowx_before_content`	Most templates, before the main content	Output markup just before the main content region.
`knowx_after_content`	Most templates, after the main content	Output markup just after the main content region.

KnowX itself attaches knowx_content_top() to knowx_before_content, knowx_content_bottom() to knowx_after_content, and knowx_sub_header() to knowx_sub_header.
