Helper Functions

The addon defines a set of global helper functions (all prefixed reign_lifterlms_) used by its templates. They are available to theme developers building custom LifterLMS views on a Reign site. Each takes a course ID unless noted.

Templates

Function	Returns
`reign_lifterlms_locate_template( $name, $path, $default )`	Resolved template path, respecting theme overrides.
`reign_lifterlms_get_template( $name, $args, $path, $default )`	Locates and includes a template with `$args` in scope.

Course data

Function	Returns
`reign_lifterlms_is_assignment_associated( $course_id )`	“Yes”/“No” whether any lesson has an assignment (needs the LifterLMS Assignments add-on).
`reign_lifterlms_is_certificate_associated( $course_id )`	“Yes”/“No” whether a certificate engagement is tied to the course or its lessons.

`reign_lifterlms_get_lesson_list_for_course( $course_id )`	A `<select>` of the course’s accessible lessons (for the distraction-free lesson picker).

Author, search and rendering

Function	Returns
`reign_lifterlms_get_author( $args )`	Author block HTML (avatar, name, optional bio).

`reign_lifterlms_allowed_html_tags()`	The `wp_kses` allow-list used for settings markup.

LifterLMS version compatibility

These wrap LifterLMS methods that changed across versions, so templates keep working across releases:

Function	Purpose
`reign_lifterlms_get_parent_course( $lesson )`	Parent course ID (handles the pre/post 5.7.0 API).
`reign_lifterlms_get_lesson_order( $lesson )`	Lesson order (handles the pre/post 5.7.0 API).
`reign_lifterlms_get_quiz_result( $query )`	Quiz attempt results (handles the pre/post 6.0.0 API).

Behavioural helpers (hooked automatically)

reign_lifterlms_body_classes adds llms-pointer and the dashboard-navigation style class to body.
reign_lifterlms_remove_sidebar_from_single_course hides the sidebar on single courses.
reign_lifterlms_remove_single_course_customizer_setting removes the theme’s single-course layout Customizer controls (the addon owns that layout).
reign_lifterlms_all_users_course_tab_option_save / reign_lifterlms_users_default_option_save seed the per-user course-tab and activity opt-in defaults (using the course_tab_flag option and user_course_option / activity user meta).
