title: Wordpress get posted in category permalink
body: <p>So each post it will be posted in one category, and for each post I want to get the posted in category permalink, only the URL <strong>without</strong> markup.
  How can I do that?</p>
  
  <p>//Explained again</p>
  
  <p>Well the post is posted in a category, right? Well I need to show that category, but not the name of the category, the url for that category.</p>
