I was thinking PHP would be required without even considering about xml/rss...

How would I accomplish this?

Essentially all I would want is "If someone from the sub-domain creates a new group, or if there is one created already - that group info get's displayed in a specific div I have created on the main-domain" - pretty much like how that information get's displayed on the "group's page" of any oxwall site - where it displays all the groups created information.

And besides the group's, I'd like this to occur for "Events", "Blogs" and possibly other things...

If it's easier, let's start with the group's - is there any snippets of code within any of the group's plugin files that I could simply copy and paste to the main-domain div I created?  Or it is much more complex than that?

Here is the link: http://stackoverflow.com/...-from-subdomain-blog

What this does is display the information from blogs posted on the sub-domain and displays it (most recent) on the main-domain.  With that being said, I'd like something very similar in context to this but workable for oxwall.

My sub-domain(s) have oxwall enabled - but my main-domain does not.  So with that being said, all I would like is to have information that is done from my sub-domain(s) be displayed on my main-domain (ie: groups created, events created, blog posts created, and possibly forum topics/posts created).

Is the best method here to create an XML/RSS or would something more complex be needed such that as an API call and/or what that link above provides?  And if so, where and how would I do this as I have no experience in those languages (XML/RSS, API, PHP).  I'm decent in HTML, CSS, and somewhat in JS, but other than that - not so much anything else.

Any help would be greatly appreciated!

I am slowly getting the gist of using iframes, but still am having issues.

<iframe src="http://www.mysitename.com/no-idea-what-needs-to-go-here-if-wanting-to-display-every-group-made-and-gets-made-in-the-future"></iframe>

This would be for groups obviously - but would also need it for blogs...Anyone?

So besides having the "Iframe" (which I still am unsure what I would need to use), I would also need this (in my case since I would be extracting this data from my sub-domain to my main-domain)...

<script type="text/javascript" charset="utf-8"> try { document.domain = 'mysitename.com'; } catch (e) {} </script>

And I would need to place that snippet of code on both pages (on sub-domain and on main-domain)....

So, final few questions here...I think I'm on the right track though...

1. What page/pages would I need to put that snippet above on my sub-domain (oxwall powered) if wanting to gather data from the groups, events and blogs to be automatically displayed on my main-domain (which is not oxwall powered)...?

2. What would be needed in the "Iframe" code in the post above for groups, events and blogs?  <iframe src="http://www.mysitename.com/no-idea-what-needs-to-go-here-if-wanting-to-display-every-group-made-and-gets-made-in-the-future"></iframe>?

I'm searching almost for the same solution. The differance is I would like to display avatars (small thumbnails) of 10 last users and 10 last photos added.

Any idea?

@Jozko, I've been researching this for awhile now but still am baffled on how to accomplish this.  If I find anything more out, I'll keep you posted by replying to this thread.

I hope if anyone has any knowledge on how to do this, they will share here as well.

XML/RSS, iframes, and/or an API would do the trick, but how would we go about making either 1 of those options work?

I've tested iframes, doesn't work correctly, unless I'm doing it wrong - simply displays the entire page of the website rather than a select portion "div" that needs to be extracted...

Any suggestions or ideas would be greatly appreciated!
