Sprout Video

In this chapter we learn how to create a new database table. This example walks through creating a module that defines the the properties of our new table and also programatically creating that table. We learn about hook_schema() and hook_update_N() in our module's install file.

Trainers note: This video starts out with a module that implements hook_node_view() and stores data about views in the $_SESSION variable. It also states that we built this earlier in the series. However, that's not true. We did talk about hook_node_view() in, but we never actually wrote the $_SESSION handling part. So, if you're following along and want the same sample code we start with make sure you download the code attached to this node.
