  Hi,
  
  Every so often I wonder if there is a pnRender function that is equivalent to the following PHP code:
  
  

  Code

  if (!empty($var))
  {
    do this
  }
  else
  {
    print error
  }

  
  
  Anyone know how to do that via a pnRender/Smarty function?
  
  Thanks,
  Grant

  I don't see "empty" anywhere in the Smarty documentation, but depending on how you handle the variables you're passing to your template, this should probably work...
  
  

  Code

  <!--[if $var ne ""]-->
      <p>This is the HTML if the variable isn't empty.</p>
  <!--[else]-->
      <p>This is your error HTML</p>
  <!--[/if]-->

  
  
  For full details, check out the Smarty docs.
