image gallery and getmedia woes

I seem to be having some major problems with getMedia within XSLT. I'm using Umbraco 4.5.1 so I know I need to use the format $currentPage/thumbnail (thumbnail being the alias of the media picker data type used on all pages).

Just so you have an idea of what I'm trying to built, the end result should be like http://and-digital.com/clients/kantar/master/index.php?site=audience&template=gallery (It's amazing how much easier it was to build as a static page)

I have the following XSLT code which can return the image path for the current page, and it works in certain cases...

<xsl:output method="xml" omit-xml-declaration="no"/>
<xsl:param name="currentPage"/>
<xsl:template match="/">
  <xsl:if test="$currentPage/thumbnail != ''">
  <xsl:variable name="media" select="umbraco.library:GetMedia($currentPage/thumbnail, false)" />
    <xsl:value-of select="$media/umbracoFile"/>
  </xsl:if>
</xsl:template>

This will work on this page

http://localhost:8080/television/people-meter-technology.aspx

But not on

http://localhost:8080/news-resources/multimedia-centre/gallery.aspx

(Obviously clicking on those will do nothing, but I think the key point is that the second one is a level deeper)

Investigating further, the XML for $currentNode when I call the XSLT macro in the second page seems to return a lot more than just the current page. It seems to return the adjascent and child nodes to it. The XML that is $currentNode is

The correct currentNode that I would expect to receive is Content node with ID 1113 which has 4 children nodes, and it's these 4 child nodes I want to then iterate over to create the gallery contents, but also to display the thumbnail for it (which it has, ID 1134)

Where am I going wrong? Any help is much appreciated, as this has been driving me crazy!

Hello Damian,
OK on this page
http://localhost:8080/television/people-meter-technology.aspx odes it have the property with the alias called thumbnail on it?

But does this page that it is not working on have the thumbnail property on it?
http://localhost:8080/news-resources/multimedia-centre/gallery.aspx

As skimming through your XML snippets above its not outputting the thumbnail property?
Did you create the pages that are not working after you added the thumbnail property, if so then you need to republish that node for the XML cache to be updated so that the property thumbnail will be added to the xml <thumbnail>1134</thumbnail>

Well, it does indeed look like there is something going in with regard to which page that is actually the current one.

Looks like to me that it is the alternateTemplates that might be giving you a hard time.

As far as I can see, the url that you actually want to visit is:

http://localhost:8080/news-resources/multimedia-centre/gallery-title-goes-here.aspx

Which is the url for the page. My guess is that you have a template called "gallery", and umbraco has a trick that means that:

http://localhost:8080/news-resources/multimedia-centre/gallery.aspx

will actuall be interpretede as

http://localhost:8080/news-resources/multimedia-centre.aspx?altTemplate=gallery

Does this make sense?

Hi Warren, thanks for the prompt reply

Both pages have the thumbnail property and both of them have something from the Media picker selected.

If my understanding is correct, the XML for $currentPage shouldn't contain the path, just the thumbnail IDs (which is has at the very end). Once I can get the correct ID it will just be a case of doing

<xsl:variable name="media" select="umbraco.library:GetMedia(THE_ID, false)" />
<xsl:value-of select="$media/umbracoFile"/>

The pages were created before (thumbnail is part of a base document type which all document types inherit from) but I've tried republishing everything just in case but it didn't make a difference =(

Any other ideas? And is it normal to get back that much XML for $currentPage instead of just the actual current page?

Thanks

Morten, you've cracked it in one! Not sure why it was publishing to that URL though as oppose to the full one (actually, now that I think about it, the node name may have been just Gallery).

So if I rename the gallery template this problem won't crop up again?

Thanks =)

In general for the $currentPage parameter, it is actually more of a "pointer" than it is an entity. I gives you the current pages "position" in the xml content cache, and from there you can navigate to anywhere else in the site.

So when doing a copy-of the $currenhtPage, you will get a copy of the entire xml struture from the current "position" in the tree.

Correct. If you rename the template it should not be a problem.

But umbraco _should_ actually prefer an actual content page over an alternate template if the both match the. So you could try and rename the page to "gallery" again, and see if it works that way as well.
