How to sync two different content types? I'm going to build a website for a magazine.I have two different content types. In the first one, I will post the first page of magazine. But in the second one is for articles.
Now, my problem is:
I want to show just articles which are related to the issue which displayed on the top. I know how to show latest content [for first content type which includes first page], but i don't know how to show its articles under it. I guess,I would use views, but I don't know how.
to be more clear: I want something like this site.
Assuming you have an Issue content type, and an Article content type

Install References and enable Node References.  On the Article content type, Add a Node Reference field (could name it "issue") and restrict its options to nodes of type Issue.

Then create a View of Articles and add (under Advanced) a Contextual Filter of Content: Issue (and if you are using url aliases for the Issues, then provide the Contextual filter with a default value of Content ID from URL).  Make it a Block display.

Then display the block on Nodes of type Issue, and it should work great for you.
