I have a website which uses a custom post type of Treatments, which we're using the CPT-onomies plugin to link as a taxonomy to other custom post types.
We have another post type, Practitioners, which I need to link related treatments too, this part is easy. But we also need to enable them to save prices per treatment and have a POA (price on application) option too.
At the momement this is rather awkwardly coded with serialised arrays, which makes long work of manipulating and reporting on the data.
What's the easiest approach to adding these two extra fields to the custom post type?
