    Dear nerds,

    i really would like to display the descripion of a TV.
    I have some 60 or so TVs and would like to display something like this:
    <table border="1">
<tr><td>[[*dtnwp]]</td><td>[[*descriptionOf[[*dtnwp]]whichMeansDistanceToNextWaypoint]]</td></tr>
</table>


    I didnt find a hint so far.

    Best Regards,

    Guido

      try this(untested) :

      create snippet ’getTvDescription’:

      <?php
//[[!getTvDescription? &tvname=`myTv`]]

$tvname=$modx->getOption('tvname',$scriptProperties,'');

if ($tv=$modx->getObject('modTemplateVar',array('name'=>$tvname))){
	return $tv->get('description');
}

return '';


      call it:

      [[!getTvDescription? &tvname=`myTv`]]
        -------------------------------

        you can buy me a beer, if you like MIGX

        Thank you a lot!

        How do I get all TVs of the same category? That is another thing I did not find by searching.

          you can try something like this snippet (also untested):

          <?php
//[[!getTvs? &category=`myCategoryId` &tpl=`tvInfo`]]

$category=$modx->getOption('category',$scriptProperties,'');
$tpl=$modx->getOption('tpl',$scriptProperties,'');

$c=$modx->newQuery('modTemplateVar');

if (!empty($category)){
	$c->where(array('category'=>$category));
}

if ($collection=$modx->getCollection('modTemplateVar',$c)){
	foreach ($collection as $object){
		$output.=$modx->getChunk($tpl,$object->toArray());
	}
}

return $output;


          with this chunk ’tvInfo’:

          <tr><td>[[*[[+name]]]]</td><td>[[+description]]</td></tr>



            -------------------------------

            Nope sad

            Where do I find the documentation on that? It really drives me nuts...
            The descriptions dont show up in the manager and with errors in the frontend output if entered via the ajax layer (quick create).
            That method seems not to use utf8 encoding sad

            Wwhen this job is done, I promise to donate to modx smiley

              I entered them all manually but am still interested in a package of that function.

              I guess thet this usage applies quite often.

                  Definitely not. It's strictly Revolution code.

                  You could do the same thing in Evo, but you'd have to write very different code.
