how to register / add multiple options into one field in wordpress?
How can I register or add multiple options into one field. For example, we save a logo in get_options() by registering the setting and adding fields by add_settings_field() function and we output it accordingly.
But what if we want to save multiple options into one field, like we have an option on our page called “Select your favourite colour” and there are check-boxes with different colours and user needs to select multiple colours (not a single colour) then how would we save that in WordPress options and how to output it too?
