Hi @Hube2 !
Thanks for your answer.
I know I have to use the “register_field_group” function and the action “acf/register_fields”. What I’m asking here is a documentation that give us information about creating manually (through code) each type of field.
Because I’m creating a SAAS where all the fields have to be created through a plugin which will be available on all subsite, I can’t (and don’t want to) use the front-end method.
Thanks,
Cédric
