title: Joomla getting Variables passed in URL
body: <p>I am trying to pull values from a URL string in Joomla when they are passed into our site. an example is:</p>
  
  <p>?source=SEARCH%20&amp;utm_source=google&amp;utm_medium=cpc&amp;utm_term=&amp;utm_content={creative}&amp;utm_campaign=&amp;cpao=111&amp;cpca=&amp;cpag=&amp;kw=</p>
  
  <p>so out of this I will want the VAR=utm_source grabbed, utm_medium grabbed etc. </p>
  
  <p>I want to carry these values across the sites and held at least until the visitor hits submit on a form so these values will be passed with the form to track these areas to see where they came from, what keywords were used etc. </p>
  
  <p>any help will be appreciated. </p>
