trying to use getResources within a IF statement, not working

That's definitely not going to work. wink

I don't think this is a job for the If snippet, and it's kind of inefficient to run getResources (which is a little slow), even when there are no books to display.

Do you have a full getResources tag that works for you to display what you want when there are books to show? Could you post the full tag here (inside code tags -- highlight the code and click on the <> in the toolbar)?

Thanks Bob. The full code is below and it works just fine. Here's what I'm looking for: If &parents=`[[*artists and poets]]` is empty, I don't want "Editions" or article.thumbList1 to appear and vice versa for Paintings and the second <article>.

<div class="artColumn col-md-8">

    <h3>Editions</h3>
	   <article class="thumbList1">
			    [[!getResources?
			        &parents=`[[*artists and poets]]`
			        &depth=`0`
			        &tpl=`boundEditionRow`
			        &includeContent=`1`
		            &limit=`10`
		            &includeTVs=`1`
		            &processTVs=`1`
		            &showHidden=`1`
		            &sortby=`menuindex`
		            &sortdir=`ASC`
			    ]]
           </article>

     <h3>Paintings</h3>
		<article class="thumbList2">
			    [[!getResources?
			        &parents=`[[*single works]]`
			        &depth=`0`	
			        &tpl=`boundEditionRow`
			        &includeContent=`1`
		            &limit=`10`
		            &includeTVs=`1`
		            &processTVs=`1`
		            &showHidden=`1`
		            &sortby=`menuindex`
		            &sortdir=`ASC`
			    ]]
		</article>
</div>

You could do this with output modifiers, but it would be significantly slower since you'd have to run getResources twice for each search, once just to see if it returns anything. This is a little more complicated, but much more efficient (untested):

Put these tags on the page:

<div class="artColumn col-md-8">

[[!GetStuff? 
   &parentTv=`artists and poets` 
   &heading=`Editions` 
   &class=`thumblist1`
]]

[[!GetStuff? 
   &parentTv=`single works` 
   &heading=`Paintings` 
   &class=`thumblist2`
]]

</div>

Create a snippet called GetStuff with this code:

<?php
/* GetStuff snippet */

$parentTv = $modx->getOption('parentTv', $scriptProperties, 'Missing Parent TV');
$heading = $modx->getOption('heading', $scriptProperties, 'Missing Heading');
$class = $modx->getOption('class', $scriptProperties, 'Missing class');

$parentTvValue = $modx->resource->getTVValue($parentTv);

$count = $modx->getCount('modResource', array('parent' => $parentTvValue));
if (!$count) { /* nothing to show */
    return '';
}

$fields = array(
    'parents' => $parentTvValue,
    'depth' => '0',
    'tpl' => 'boundEditionRow',
    'includeContent' => '1',
    'limit' => '10',
    'includeTVs' => '1',
    'processTVs' => '1',
    'showHidden' => '1',
    'sortby' => 'menuindex',
    'sortdir' => 'ASC',
);


$output = "\n<h3>" . $heading . '</h3>' .
    '   <article class="' . $class . '">' . "\n";

$output .= $modx->runSnippet('getResources', $fields);

$output .= "\n    <article>\n";

return $output;

I mostly understand what's going on, in running getResources only once. I added the GetStuff in the template and created the GetStuff php snippet. But no change. It still show both h3's.

Did you remove any calls to getResources on the page?

Did you clear the site cache and your browser cache?

Do the container pages identified by the ID value stored in the TV have no children at all (no deleted, unpublished, or hidden pages, and no sub-container)? If there are any of those, the snippet will see that the parent has children and will go ahead and run getResources so you'll still see the HTML for the output.

I commented out the calls to the getResources code. Cleared all caches when I first tried your code. No, there are no children of any kind, at least I don't think so.

Let me explain the template structure: I create a resource for an artist, then if their are single works for this artist, I create a container resource with the artist's name, and place the work in this container. Then I can link the container to the artist, and the artist to the container using the template variables -- artists and single works. If there are no editions (artists and poets), there is no container and no link between the artist and the non-existent container.

Hop this is clear.

I think I may see the problem. I thought that the stuff you want to show was direct children of the pages named in the TVs. It sounds like it's grandchildren. Is that the case?

I got it to work with a few tweaks of your code. Many thanks.


<?php
/* GetStuff snippet */
 
$parentTv = $modx->getOption('parentTv', $scriptProperties, 'Missing Parent TV');
$heading = $modx->getOption('heading', $scriptProperties, 'Missing Heading');
$class = $modx->getOption('class', $scriptProperties, 'Missing class');
 
$parentTvValue = $modx->resource->getTVValue($parentTv);

if (!$parentTvValue) { return ''; } /* nothing to show */

$fields = array(
    'parents' => $parentTvValue,
    'depth' => '0',
    'tpl' => 'boundEditionRow',
    'includeContent' => '1',
    'limit' => '20',
    'includeTVs' => '1',
    'processTVs' => '1',
    'showHidden' => '1',
    'sortby' => 'menuindex',
    'sortdir' => 'ASC',
);

$output = "\n<h3>" . $heading . '</h3>' .
    '   <article class="' . $class . '">' . "\n";
 
$output .= $modx->runSnippet('getResources', $fields);
 
$output .= "\n    </article>\n";
 
return $output;
