title: OpenCart variables in home.tpl
body: <p>So i'm trying to display the categories on the homepage in a custom theme of OpenCart.</p>
  
  <p>In the header.tpl you can use variables as <code>$categories</code> and so fort, but when I want to use these variables in the home.tpl file, it says it doesn't exists.</p>
  
  <p>Is there any way to make these variables working in the home.tpl file? I can't find any line in the header.tpl that includes a PHP files where all these variables can be found.</p>
