[Solved] How can I conditionaly hide whole section of page

13 Posts

I’ve got news section on my page - something like:

<h1>News</h1>
[[$news-section]]

Inside the news-section snippet there is a getResource call.
What I want to do is to not show this whole section if getResource returns no news at all.
Is there any easy and DRY way to do it?

PS. I’ve tried output filters like :ifempty etc, but unfortunatelly getResource in chunk is not parsed, so ifempty is always false.

I don’t know about DRY, but couldn’t you have the getResource function (not in a chunk) save its output to a placeholder, then use the conditional on the placeholder?

You could try wrapping the title inside first template for GetResources (tpl_{n} syntax):

P.S: don’t have Revo public release installed anywhere handy... wink

Heh - I didn’t thought about that:) I think it will be the best solution and also the easiest one to implement - I will try it and get back to you

Thanks

Ok - I’ve got it working - example code below for others:

[[!getResources? 
  &parents=`41` 
  &hideContainers=`1` 
  &tpl=`publication-list` 
  &toPlaceholder=`publication-list`
  &limit=`5` 
  &sortby=`publishedon` 
  &includeTVs=`1` 
  &processTVs=`1` 
  &tvFilters=`specializations==%[[*id]]%`
]]

[[!+publication-list:notempty=`
<div id="pubs">
<h1 class="decorated"><span>Publikacje</span></h1>
<ul class="pub-list">
[[+publication-list]]
</ul>
(...)
