title: Joomla Session Variable as Plugin Parameter
body: <p>I have a Joomla plugin which takes varying parameters.  I need to retrieve one of these parameters from the current session.  I've tried using Jumi and a little PHP snipped to retrieve the value and output it in the plugin's parameter list, but the Joomla plugin parser only handles the outter-most set of curly braces.  ex.</p>
  
  <pre><code>{fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id=[tour_id]}
  </code></pre>
  
  <p><code>[tour_id]</code> I need to retrieve from the current session.  I've tried</p>
  
  <pre><code>{fabrik view=table id=62 resetfilters=1 fab_tours_ro___tour_id={jumi [scripts/get_tour_id.php]}}
  </code></pre>
  
  <p>In that case the <code>{jumi}</code> tag never gets parsed.  I could hack the <code>{fabrik}</code> plugin, but I'd prefer to do this without making any core or component changes, especially since I update Fabrik quite regularly via svn.</p>
