I`m developing a wordpress multisite network, so far everything is going fine. But I would like to add an "Options Page" to all the network blogs, in this page users would have access to some custom fields where they would be able to insert informations about their website, like: logo, contact, etc. So in their theme they would have all those informations displayed.
The question is, how can I do that? I have been using custom post types for some time now, but as long as this is going to be a one page control panel I`m not really sure about how to do that. Also, to create custom fields I have been using a plugin called Advanced Custom Fields, so, is there any way that I can install this plugin with some custom fields created on those websites? Or is there any other way to achieve this result without any plugin?
All the best!
