Conditional Template Variable Snippet

Hello,

I have a url template variable with a default value of "none".

For pages with a custom url that I type in this field I want it to display a link with the specified url, however for pages with simply the default value of "none" in the url field I don’t want anything to display.

This is the snippet that decides what to display.
```
<?php
$cslink = "[+CaseStudy+]";
if($cslink != "none"){
echo '<a href="[+CaseStudy+]">Case Study</a>';
}
elseif($cslink == "none"){
echo "";
}
?>
```
It works without the elseif statement, however the Case Study link is displayed on all the pages. When I take out the elseif statement then it won’t display anywhere.

Give this a try:

<?php

$thisid = $modx->documentIdentifier;
$output ='';
$cslink = $modx->getTemplateVarOutput(array("CaseStudy"), $docid=$thisid);

if($cslink['CaseStudy'] != "none"){
    $output .='<a href="'.$cslink['CaseStudy'].'">Case Study</a>';
}

return $output;
?>
