Hi,

I have an snippet that should read the Template-ID of the current resource.
I try this:

$template = $modx->resource->get('template');

But this will work only when I call this snippet in a "regular" document.

e.g. When I call the snippet inside a chunk for e.g. getResources (I want read the templates from all listed documents)
that outputs me only the Templat-ID from then Dokuments where the getResources call ist located and not from all the specific
documents that are listet.

That’s because $modx->resource is *always* the currently loaded document. If you’re calling a snippet in getResources, you need to pass in the current ID in the iteration:

[[!mySnippet? &resourceId=`[[+id]]`]]

And then access it via:

$resource = $modx->getObject('modResource',$resourceId);

This prints nothing out:

$resource = $modx->getObject('modResource',$resourceId);
echo $resource;

It stays empty.

$resource = $modx->getObject('modResource',$resourceId);
$template = $resource->get('template');
echo $template;

The point is that $resource stays empty.

I call it so:
[[!chkTemp1? &resourceId=`[[+id]]`]]

Snippet:

$resource = $modx->getObject('modResource',$resourceId); 

$doc = $modx->getObject('modResource', $resource); 
$template = $doc->get('template');

Sorry, just checking, do you return the value? It is not in the snippet you show.

return $template;

The code in your snippet works for me.

Another way is to use the add-on getResourceField.

[[!getResourceField? &id=`[[+id]]` &field=`template`]]

I use it all the time. (I see there is an add-on called getValue, perhaps that one does the same, haven’t checked.)

Still not working:

I try many things. E.g.

$resource = $modx->getObject('modResource',$resourceId);
$template = $resource->get('template');
echo $template;
echo $resource;

$template bring me the current template (*)
$ resource is still empty

(*) But wehen I put this snippet inside a chunk for e.g. getResources it prints me out the Template from the documente where
the getResources call is located. But I want the Template-IDs from all listet documents.

No I can not use GetResourceField in this case.
I work with a search snippet. The Search Results have to be filtered what template the result has.
The Problem ist that the SearchSnippet dont work with the IF-Snippet or the Input/Output filters.
(statement from the programmer of the snippet)

So the solution is to write a snippet and locate it inside the chunk that show the results:
e.g the chunks look like this

<a [[snippet]] href="blabla.html">Blabla</a>

The snippet should do that:
Pseudo-Code:

If Template = 10 then
return 'class="pop"'
