Create content type with database connection
Hello,
I would like to create a new content type in H5P that loads content from a database (Drupal 7, PostgreSQL).
I find it hard to make my way from the Hello World greeting card tutorial to such a complex plugin.
It would be helpful if anybody could tell me if there is already a plugin with database connection where I can look at how it works. Or if anybody could tell me what to read to get all the information I need.
