I've been tasked with my first WordPress project. It's a project that involves custom plugin development. While looking over the documentation for adding custom post types I found the meta boxes functions.
I'm a bit confused. Does WordPress require it's developers to manually save, sanitize, validate all the meta boxes? Are there no pre-built options for simple data such as text, textarea and similar?
Really my question maybe boils down to are registering custom post types and meta boxes and manually handling the said above the correct path while developing a plugin for registering different events that would, for example, include inputs for dates, street addresses and such.
