Get Document Path based on child document ID

Hi Everyone,

I was looking for a way to find a document’s path relative to the site url. So, for example, I have a document 3 deep and I want to prepend it’s parent’s alias’s, and pass it through a chunk for display. I somehow had this working, but then the MODx install got corrupted and I had to do this portion over. So, I’m guessing there is an easier way to do this.

I created a snippet to find documents based on a TV and have the results gathered through this while loop:

  while($row = $modx->db->getRow( $results )) {
    $alias = $row['alias'];
    $pagetitle = $row['pagetitle'];
    $path = getDocumentPath($alias,$row['id']);
    $output .= $modx->parseChunk($tpl, array('alias' => $alias, 'pagetitle' => $pagetitle), '[+', '+]'  );
  }

Here is the getDocumentPath function:

function getDocumentPath(&$path,$docId, $separator = '/') {
  global $modx;
  $parent = $modx->getParent($docId, 1, 'alias,parent,id');
  $path = $parent['alias'] . $separator . $path;
  if($parent['parent'] != 0) {
    if(getDocumentPath($path,$parent['id'])) return true;
  }
  else {
    return true;
  }
}

I was just curious if this was already built into MODx, if something out there already exists to do this (non-core MODx), or if someone else needs a similar function to do the same thing.

Cheers,
Shawn

A co-worker reminded me of how I did this originally. In my chunk I had the id as [~[+id+]~]. Oh well, maybe someone will find this function useful.

[~id~] (or [~[+id+]~] which would be the way to use it in a snippet tpl) is the syntax for modx to create an internal link. The cool thing is that the link is created according to your SEO URL settings.

A more efficient way to get the path in snippet or plugin code would be using $modx->aliasListing. Something like this will avoid any additional queries to the database:

<?php
function getDocumentPath($docId) {
$path = ’’;
$docId = intval($docId);
$exists = array_key_exists($docId, $modx->aliasListing);
if ($exists) {
$path = $modx->aliasListing[$docId][’path’];
}
return $path;
}
?>
