Multi-site install with superadmin content control

Permalink
I have found a few articles on Multi-site installation but I don't think it is what I am looking for. I need to set up a C5 install that can deliver global content to many smaller websites that will need their own unique content as well.

All the sites I am creating will have the same template, same page types, some of the same content blocks and same site structure. For example every site will be set up like this:

Site-one: home (shared and individual site content)
about us (shared and individual site content)
news (individual content)
site-two: home
about us
news
site-three: home
about us
news

(edit to add)

On the home page all 10 sites will have a block that is called "upcoming company events". It is easy to display that block on all 10 sites, but each site also needs a block called "Regional events". When an end use visits any one of those 10 sites, they should see the same "upcoming company events" block on all the sites but each site will have different information in the "regional events" block.

The super admin needs the ability to add content that will appear on all of the domains and their sub pages, or just some of the domains. Some sites will share sub pages that the other sites can't see.

I have 10 domains that will have their own admins, so site specific content can be added to each domain by it's respective admin. If the admin of a domain wishes to add new blocks or new pages to the site, these blocks and pages will not show up on the other domains and the super admin will not need to set anything up or approve any pages.

My question is, does anyone have any ideas how this can be set up or if it can be done? What would this set-up look like? How do I go about setting it up so a super admin can add global content that will automatically appear on all the sub pages and domain admins can add their own content without needing the approval of a super admin.

Thanks, any help to point me in the right direction is appreciated.

hello,
I can't really comment about exactly what you are attempting to do except that when I read the description and tried to visualise the end result I thought maybe you are approaching it in a more complicated way than you need.

If the superadministrator does not need to approve content ot in fact needs do nothing other than deliver content to the websites...

Might it not be possible to run all of your subsites which are identical and then just iframe or ajax in your 'master' or 'common' content from another place (speradmin backend website or whatever)..

That way you just need your base website replicated a number of times without getting too complex...

Apologies if I've misunderstood and this approach won't do what you want.

I am open to any idea's, I only have an imagination that goes as far as what I have already seen and done.

I think that might work but I am not sure how to go about adding a specific content block from a page do another page with an iframe or ajax. I can do whole pages easy but have never done part of a page.

If I understand what you need correctly, check out advanced permissions.

I thought about advanced permissions too, and maybe my question is not very well explained, but lets use the home page as an example.

All 10 sites have a block that says "upcoming company events" on the home page. It is easy to display that block on all 10 sites, but each site also needs a block called "Regional events". How do I use advanced permissions so that the end user who is not logged in will see the regional events specific to the site they are visiting?
