I modified the FirstChildRedirect snippet and think this might be of use to someone else. I needed a way to redirect a user to the first child of a document if there is only one child. I’ve dubbed this "OnlyChildRedirect". Here’s your code:
<?php
/**
* @name OnlyChildRedirect
* @author Jason Coward <[email protected]>
* @modified-by Ryan Thrash <[email protected]>
* @modified-by Dave Child <[email protected]>
* @license Public Domain
* @version 1.0
*
* This snippet redirects to the first child document of a folder in which this
* snippet is included within the content (e.g. [!OnlyChildRedirect!]) if there
* is only one child present. This allows MODx folders to emulate the
* behavior of real folders since MODx usually treats folders as actual
* documents with their own content.
*
* Modified to make Doc ID a required parameter... now defaults to the current
* Page/Folder you call the snippet from.
*
* &docid=`12`
* Use the docid parameter to have this snippet redirect to the
* first child document of the specified document.
*/
$docid = (isset($docid))? $docid: $modx->documentIdentifier;
$children= $modx->getActiveChildren($docid, 'menuindex', 'ASC');
if ((!$children === false) && (count($children) == 1)) {
$firstChild= $children[0];
$firstChildUrl= $modx->makeUrl($firstChild['id']);
return $modx->sendRedirect($firstChildUrl);
}
return '';
?>
