Get the parent

Here are 11 examples on how you can get the parent of the current document in MODx.

Using a snippet

UltimateParent

<?php
/*UltimateParent*/
$parent = $modx->runSnippet("UltimateParent");
echo  'UltimateParent: ' . $parent;
?>

GetField

<?php
/*GetField*/
$parent = $modx->runSnippet("GetField", array('field' => 'id', 'parent' => '1'));
echo  'GetField: ' . $parent;
?>

ParentParent

<?php
/*ParentParent*/
$parent = $modx->runSnippet("ParentParent");
echo  'ParentParent: ' . $parent;
?>

Using MODx API

getParent

<?php
/*getParent*/
$parent = $modx->getParent($modx->documentIdentifier,'','id');
echo  'getParent: ' . $parent['id'];
?>

getParentIds

<?php
/*getParentIds*/
$parent = $modx->getParentIds($modx->documentIdentifier);
echo  'getParentIds: ' . reset($parent);
?>

getDocument

<?php
/*getDocument*/
$parent = $modx->getDocument($modx->documentIdentifier, 'parent');
echo  'getDocument: ' . $parent['parent'];
?>

getPageInfo

<?php
/*getPageInfo*/
$parent = $modx->getPageInfo($modx->documentIdentifier, '', 'parent'); 
echo  'getPageInfo: ' . $parent['parent'];
?>

Using MODx DBAPI

db->select + db->getValue

<?php
/*db->select + db->getValue*/
$parent = $modx->db->getValue($modx->db->select("parent", $modx->getFullTableName('site_content'), "id=" . $modx->documentIdentifier));
echo  'db->select + db->getValue: ' . $parent;
?>

db->select + db->getRow

<?php
/*db->select + db->getRow*/
$parent = $modx->db->getRow($modx->db->select("parent", $modx->getFullTableName('site_content'), "id=" . $modx->documentIdentifier));
echo  'db->select + db->getRow: ' . $parent['parent'];
?>

db->query + db->getValue

<?php
/*db->query + db->getValue*/
$parent = $modx->db->getValue($modx->db->query( 'SELECT parent FROM ' . $modx->getFullTableName('site_content') .' WHERE id =' . $modx->documentIdentifier ));
echo  'db->select + db->getValue: ' . $parent;
?>

db->query + db->getRow

<?php
/*db->query + db->getRow*/
$parent = $modx->db->getRow($modx->db->query( 'SELECT parent FROM ' . $modx->getFullTableName('site_content') .' WHERE id =' . $modx->documentIdentifier ));
echo  'db->query + db->getRow: ' . $parent['parent'];
?>

haha, wow .. that's a lot :) / wouldn't it be better to use "return" instead of "echo"?
thanks, j

Hi sharkbait,

I couldn't find a reason why return is better than echo. The code is executed using eval and I don't think eval cares about it.

Can you please post an example of why return is better? Thanks

Hi cipa,

couldn't find a very detailed post, but i've read many times that it's best practice. Echoing works too, but the results might be unpredictable sometimes

Unfortunately return doesn't always work when you call a snippet inside another snippet. I remember having a problem with the includeTemplate snippet I use to keep my templates in files.

So 12 ways ;)
Unfortunately you can't use [ * parent * ] in your custom snippets.
Thanks
