How to output a chunk or message if getPage is empty in MODX Revo 2.x

Question

I have this construction:

[[!getPage? 
&element=`getResources` 
&limit=`10` 
&tpl=`vacancy_tpl` 
&parents=`[[*id]]` 
&includeContent=`1` 
&includeTVs=`1` 
&showHidden=`1` 
&pageFirstTpl=`<li class="control"><a[[+classes]][[+title]] href="[[+href]]">First</a></li>` 
&pageLastTpl=`<li class="control"><a[[+classes]][[+title]] href="[[+href]]">Last</a></li>
`]]

How can I output a message or chunk if there are no results returned by getPage call?

Answer 1

There is an easier way to do it, just use modx input/output filters -

[[!getPage:empty=`<div>[[$your_chunk]] or your message</div>`? 
    &element=`getResources` 
    &limit=`10` 
    &tpl=`vacancy_tpl` 
    &parents=`[[*id]]` 
    &includeContent=`1` 
    &includeTVs=`1` 
    &showHidden=`1` 
    &pageFirstTpl=`<li class="control"><a[[+classes]][[+title]] href="[[+href]]">First</a></li>` 
    &pageLastTpl=`<li class="control"><a[[+classes]][[+title]] href="[[+href]]">Last</a></li>
