url to link back to containing document from symlink

Using Revo 2.2.6

I'm trying to find the URL needed to link back to the parent document from within a template applied to the Symlink.

I've tried:



I'm sure it's something simple that I'm missing, but just wasted about 45 minutes searching for the answer online.

Thanks a million!

Do you mean the resource that the symlink is taken from?

Yepper! Thanks sottwell.

Hm. Have been doing some experimenting with symlinks. They behave rather oddly. I had expected that just the content field from the resource linked to would be inserted. The content of the symlink in the database is the ID you're linking to, but it's proving very difficult to get at that value.

Sometimes the pagetitle, longtitle, description, introtext will be the same as the resource being linked to, sometimes it will be that of the symlink resource. Having the various tags uncached seems to help.

A snippet to get the class_key always returns modDocument, even though it's obviously a modSymLink. A snippet to get the content directly from the database will return the linked resource's content.

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

Thank you for your efforts. It's nice to know I'm not crazy, that it wasn't as simple as I thought it should be. I will play with this and report back on how it works out.

I can get the actual content (the ID of the linked resource) using @SELECT binding for a TV - but only if I specify the actual ID of the symlink:

So you could use such a TV but it would have to be edited for each symlink to use its own ID. [[*id]] didn't work there at all, nor did a snippet to get the ID.

Got it! Use a snippet:



the raw xPDO query doesn't process symlink content the way that the modResource object does.

You are brilliant! Thank you. Copying this straight into a snippet, removing the output prefix of Result: gave me exactly what I needed (just the id number of the parent document) to create the back-links dynamically. Sorry for the delayed reply - I put this project to the side for the weekend and just came back to it. I really really really really REALLY appreciate your help.

Got it! Use a snippet:

$thisId = $modx->resource->get('id');
$result = $modx->query("SELECT * FROM modx_site_content WHERE id=$thisId");
if (!is_object($result)) {
   return 'No result!';
}
else {
   $row = $result->fetch(PDO::FETCH_ASSOC);
   return 'Result:' . $row['content'];
}
return;
