I need to know: I have wrote at 60% one plugin, it works well in backend (some settings, some cpt, some custom fields... nothing special). It uses custom post type with custom fields.
For now I need to change default archive category behaviour as well as change behaviour of single posts of this CPT _doesn't_touching_ templates (because this plugin will be used not only in the 1 site and there will be many templates).
Just programmatically, by filters/actions - change it as I like.. for example, I will need to show up this custom fields in this single custom post type.
Does somebody knows about how to do it by plugin?
