    I have a template variable that is only for uploading files for users to download. Some of the resources won’t have this content and some will - how do I show the code only if there is content in the resource to download?

      Easiest way is to have a separate template and assign the TV to only that template.

        Well it’s from the same resource, so some resources will have downloads and some wont. I know I can have two templates and select the different one if there is no download, but isn’t there a more elegant way of doing it?

          Do you mean the TV in the Manager or the associated html of a possibly empty TV at the front end?

            The latter.

            I basically have this code to display in the front end.

            <a href="[*download*]">Download PDF</a>


            But I only want that code to show if there is actually a file being added to the download field.

              Put the code below into a snippet, then call the snippet instead of <a href="[*download*]">Download PDF</a>
              <?php
$tv = $modx->getTemplateVarOutput(true, $modx->documentIdentifier);
$value = $tv['download'];
return empty($value)? "" : '<a href="'.$value.'">Download PDF</a>';
?>
