[TYPO3-ttnews] Hide news if no content is shown

[Ralf Heydenreich]

Hi all,
I want to hide the news block if there are no news to display. Therefore
I have defined a div tag around the news block where I can set the style
to "display:none" (works with TemplaVoilà). Unfortunately, I don't know
how to test if there's no content. The following solution does NOT work:

lib.field_event < plugin.tt_news
lib.field_event {
# ... some configuration stuff ...
  displayLatest {

    # Count the news items
    subheader_stdWrap = COA
    subheader_stdWrap {
      # start/update counter
      20 = LOAD_REGISTER
      20.news_count.cObject = TEXT
      20.news_count.cObject.data = register:news_count
      20.news_count.cObject.wrap = |+1
      20.news_count.prioriCalc = intval
    }
  }
}

lib.event_hider = TEXT
lib.event_hider.insertData = 1
lib.event_hider.value = display:none;
lib.event_hider.if.isFalse.data = register:news_count


The register value is ignored/not set (don't know how to test it). In
the plugin source code I found the (internal) variable
$this->internal['res_count']. Perhaps this could be used for external
access? Any hint is welcome...

TIA,
Ralf
