Hi i’m trying to make a custom filter. But making a snippet and prefixing it with phx:MySnippet doesn’t work anymore.
So, i was trying to make a filter that will check if the description is empty or not. if not empty write the proper div around it
```
[[description:intro]]
```
and in the snippet ’phx:intro’
```
<?php
if(strlen($output)>0){
   $newValue = "<div class='intro'>". $output ."</div";
}else{
   $newValue = '';
}
return $newValue
```
how can i do this now?

Tnx

Hoping I understand you correctly, what I would try is to first download the If snippet. Then call it with something like:
```
[[!If? &subject=`[[*yourTVorDescriptionOrWhatever]]` &operator=`empty` &then=`` &else=`<div id="whateverDIVname">[[*yourTVorWhatever]]</div>`]]
```
Hope it helps.
