title: How to set properties for post while posting news feed using graph api
body: <p>I am trying to set properties of post. And I am posting news feed using curl.</p>
  
  <p>I am setting properties like this but it is not working.</p>
  
  <pre><code>$message = 'Message 1';
  $caption = 'Caption 1';
  $media["properties"] = array('category' =&gt; array( 'text' =&gt; 'humor', 'href' =&gt; 'http://www.icanhascheezburger.com/category/humor'));
  $media["media"] = array("type" =&gt; "image", "src"=&gt; $imageUrl , "href"=&gt;$link);
  $attachment = array ('name' =&gt; $caption,
               'link' =&gt; $appUrl ,
               'caption' =&gt; 'Test Caption',
               'description' =&gt; $message,
               'attachment' =&gt;  $media
              );
  </code></pre>
  
  <p>Feed is getting published, but properties are not coming.</p>
  
  <p>Please suggest me to how I should set the properties.</p>
