Anyway to use getResources as an RSS Feed?

Not sure if this is possible, and if it is the only method I can see is to somehow use the template to turn it into valid xml content.

If anyone could help this would be great, or an example rss chunk. ^_^

Sure, it’s possible to use getResources to generate an RSS feed. Here’s an example:

Create a document, use the blank template, set the content type to XML and paste this in:

<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
<channel>
<title>[[*pagetitle]]</title>
<link>[[++site_url]]</link>
<description>[[*description]]</description>
<lastBuildDate>[[!getTime?format=`%a, %d %b %Y %H:%M:%S %z`]]</lastBuildDate>
<language>en-gb</language>

[[!getResources? 
   &parents=`3`
   &limit=`10`
   &sortby=`createdon`
   &sortdir=`DESC`
   &includeTVs=`1`
   &includeContent=`1`
   &tpl=`rssListing`
]]

</channel>
</rss>

Adjust the &parents value to the container where you’re saving your pages that you wish to be in your RSS feed. You’ll also notice I have a getTime snippet call in there for the lastBuildDate element, that’s just a snippet that returns the current time in a particular format. The snippet content is:

return strftime($scriptProperties['format']);

Then, for the rssListing chunk, I’ve used this:

<item>
<title>[[+pagetitle]]</title>
<link>[[~[[+id]]]]</link>
<guid>[[~[[+id]]]]</guid>
<pubDate>[[+createdon:strtotime:date=`%a, %d %b %Y %H:%M:%S %z`]]</pubDate>
<description><![CDATA[ [[+introtext]] ]]></description>
</item>

That’s all I needed to get a basic RSS feed working on my (in-development) blog site. Hope it helps

FWIW, I use a custom output filter to wrap the fields in CDATA tags (to avoid any parser issues since it ends with the double-brackets, e.g. "]]"). Here is the snippet:

<?php
return "<![CDATA[{$input}]]";
?>

And then my tpl looks something like:

<item>
<title>[[+pagetitle:cdata]]</title>
<link>[[~[[+id]]]]</link>
<guid>[[~[[+id]]]]</guid>
<pubDate>[[+createdon:strtotime:date=`%a, %d %b %Y %H:%M:%S %z`]]</pubDate>
<description>[[+introtext:cdata]]</description>
</item>

As always, thank you very much opengeek laugh

.

That really helped me out. Was trying to figure it out last night but I suppose I was too tired tongue

And overall props to getResources. I run multiple instances of it on a single page, and have little to no page load time increase.

How do I add this output filter into MODx Revolution? Is it just a snippet with the name "cdata"?

Yep. Any snippet can be an output filter. See: http://svn.modxcms.com/docs/display/revolution/Input+and+Output+Filters

Thanks for the tipp with the :cdata output filter, works great!

I needed it to make a flash videogallery controllable with modx (create the xml with getRessources) but I had the Problem, that every textblock that was wrapped in cdata Tags had some whitespace at the beginning...I had a look into the core "core/model/modx/filters/modoutputfilter.class.php" and there was the problem, the whitespace is already in the code, I changed it to:

                    case 'cdata':
                        $output= "<![CDATA[{$output}]]>";
                        break;

and now the problem is gone...I don’t know how to file a "bug" like this, but if this could be changed in the core, it would be great!

keep up the good work!

EDIT: OK, I tried to open a ticket in the bugtracker, hope I did it right...

This is a feature not a bug, to prevent JS problems when it appears within the CDATA tags. It’s a tag conflict issue. Why is the whitespace a problem? And if it is, you can create your own filter to wrap in CDATA without the whitespace.

How do I remove the time from this?

<pubDate>[[+createdon:strtotime:date=`%a, %d %b %Y %H:%M:%S %z`]]</pubDate>

I tried just deleting the %H %M %S but that just gave me a default time for everything.

Thanks
