This plugin must be used with <a href="https://wordpress.org/plugins/simple-course-creator/" rel="ugc">Simple Course Creator</a>.
By default, the only way to know that a post is part of a Simple Course Creator course is by viewing the individual post page or another post in the same course. This add-on allows you to see if a post is part of a course in “byline” fashion. The name of the course a post is part of can be seen from the blog home, archive, or search results.

Simple Course Creator Front Display

Outputs the course name on each post listed on a blog home, archive page, or search results page.
