(I have some experience creating Wordpress themes but no experience in extending Wordpress functionality. I'm sure this must be a very common question, but I don't know how to search for the answer. All I could find is how to create custom menu items.)
How can I create custom object types / entities in the database, like
- Team members, i.e. an entry for each team member of the company
- Reference projects, i.e. an entry for each project the company has done
In the admin panel, it looks like this:
For each object type, I want to define what properties they have (title, name, description, notes, image 1, image 2).
How can I do that? For what keywords should I search?
