Links on Social Media/metadata - metadata

Question

I have done several searches trying to find a solution with no luck. I'm hoping someone here can help.
For a while I was having a problem with my links on Facebook not showing the thumbnail or the description to my blog posts. They just showed a standard description and always linked to my home page. I was able to fix that issue by changing the metadata to the following:
<meta property="og:type" content="article" />
<meta property="og:url" content="<?= "http://www.calsots.com".$_SERVER['REQUEST_URI']; ?>" />
<meta property="og:title" content="<?= urldecode($_GET['title']) ?>" />
<meta property="og:description" content="<?= urldecode($_GET['description']) ?>" />
<meta property="og:image" content="<?= $_GET['image'] ?>" />
Now, I'm having an issue with G+. When I post a link the thumbnail doesn't show and there is no description. Any thoughts on how to fix this? I do have additional metadata for G+.
<meta itemprop="name" content="">
<meta itemprop="description" content="">
<meta itemprop="image" content="">
I have tried changing the content to calls, direct descriptions, I've left it blank and I even removed it but nothing is working.

The markup for the Google+ fragment you've provided isn't a full schema.org microdata set. Although it provides the data, you haven't shown if the page itself is setup correctly to indicate the itemscope and itemtype. You should also avoid the meta tags themselves, if possible, instead indicating the itemprop attribute on existing page elements.
See http://support.google.com/webmasters/bin/answer.py?hl=en&answer=176035 for more information about microdata in general, http://schema.org/docs/gs.html#microdata_how for details about how to markup your page with microdata, and https://www.google.com/webmasters/tools/richsnippets for the structured data testing tool, which can help determine how Google sees your page.
