title: Access a column in a database Eloquent Laravel4
body: <p>I need to be able to access all the data in one of the columns of my table. My initial approach was to do something like this. The column i am trying to access in my database is called 'Tags'</p>
  
  <pre><code>//get all posts 
  $post = Post::get();
  
  //get all post tags
  $post_tags = $post['tags'];
  </code></pre>
  
  <p>but this returns null. I know there will be an extremely simple way to do it, i am just not seeing it!</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>The reason i am doing this is i have a tagging system in place when something is posted you can add 3 tags which relate to that post. What i am trying to do in the long run is when a tag is clicked it will filter out all the posts with that set tag.</p>
  
  <p>The way this works is when a tag is clicked the user will be redirect to a url like so</p>
  
  <pre><code>//test-site.com/posts/tags/{tag}
  </code></pre>
  
  <p>so ill be using that tag to then query the database for the results. I have managed to confuse myself in a task i thought would be farily simple!</p>
