hi there, is it possible to call a snippet within a snippet call? ie:

[[Wayfinder? &startId=`[[GetParentID]]` &level=`1` &removeNewLines=`true`]]

my "GetParentID" returns either the parentID or the current ID depending on whether the current document has a parent or is in the root:

$thisID = $modx->documentObject['id'];
$parentID = $modx->getParent($thisID,0,'id');

if(empty($parentID['id'])){
  return $thisID;
}else{
  return $parentID['id'];
}

if this is not possible, how else could i achieve the same effect?

many thanks!

Yes, you can. Right now there is a limitation that prevents you from nesting a snippet with the same caching type.

Try:

[!Wayfinder? &startId=`[[GetParentID]]` &level=`1` &removeNewLines=`true`!]

This should be fixed in version .97

This is documented here:
http://wiki.modxcms.com/index.php/Common_snippet_error_messages_and_their_meaning

Under " Parse error, "Execution of a query to the database failed - You have an error in your SQL syntax near ’[[...""

"Regret for the things we did can be tempered by time; it is regret for the things we did not do that is inconsolable."

For more control until the parser in 0.9.7 is available, you can also create a snippet that simply calls the snippets via the API, e.g.

<?php
$startId= $modx->runSnippet('GetParentID');
return $modx->runSnippet('Wayfinder', array (
    'startId' => $startId, 
    'level' => 1, 
    'removeNewLines' => true
));
?>

i always wondered what the difference between [[ ]] and [! !] was

OpenGeek:
i also didn’t know that you could call snippets like that. that will come in useful another day!
