Link to parent doctype from for-each

Hi.

My problem is that I can't find a way to link to GalleryItem from within the inner for-each which is creating the link to the specific gallery.

Here's the XSLT (stripped down from everything unnesseceary):

<xsl:variable name="Folder" select="$currentPage/GalleryItem [not(umbracoNaviHide = 1 )]"/>
<xsl:for-each select="$Folder">
  <xsl:variable name="Images" select="umbraco.library:GetMedia(blaaahFolder, false())" />
  <xsl:for-each select="$Images">
    <a>
      <xsl:attribute name="href">
        <xsl:value-of select="umbraco.library:NiceUrl(ID of doctype GalleryItem which contains the blaaahFolder-node)" />
      </xsl:attribute>
      <xsl:attribute name="target">_self</xsl:attribute>
      <img>
        ...         
      </img>
    </a>
  </xsl:for-each>
</xsl:for-each>

The output from a copy-of is:

<GalleryItem id="1192" parentID="1188" level="3" writerID="0" 
creatorID="0" nodeType="1185" template="1162" sortOrder="0" 
createDate="2011-09-30T18:35:12" updateDate="2011-10-12T00:56:25" 
nodeName="Første galleri" urlName="foerste-galleri" writerName="" 
creatorName="" path="-1,1164,1188,1192" isDoc="">
<blaaah>1207</blaaah>
<blaaahFolder>1210</blaaahFolder>
</GalleryItem>

<GalleryItem id="1193" parentID="1188" level="3" writerID="0" 
creatorID="0" nodeType="1185" template="1162" sortOrder="1" 
createDate="2011-09-30T18:50:55" updateDate="2011-10-12T02:08:22" 
nodeName="Andet galleri" urlName="andet-galleri" writerName="" 
creatorName="" path="-1,1164,1188,1193" isDoc="">
<blaaah>1200</blaaah>
<blaaahFolder>1206</blaaahFolder>
</GalleryItem>

The id I need is the very first (1192 and 1193 (every gallery created with GalleryItem),
but I can't find a way to get it right :-/

The structure is: GalleryPage/GalleryItem
Currentpage is GalleryPage

The images are picked with the Media Picker for every folder. The alias for the Media Picker is blaaahFolder (sorry for the odd naming-scheme - it's just a temporary solution...).

Hi Stefan,

You can grab that ID before going into the second loop:

<xsl:variable name="Folder" select="$currentPage/GalleryItem[not(umbracoNaviHide = 1 )]" />
<xsl:for-each select="$Folder">
    <xsl:variable name="Images" select="umbraco.library:GetMedia(blaaahFolder, false())" />
    <xsl:variable name="GalleryItemID" select="@id" />
    <xsl:for-each select="$Images">
        <a href="{umbraco.library:NiceUrl($GalleryItemID)}" target="_self">
            <img>
            ...         
            </img>
        </a>
    </xsl:for-each>
</xsl:for-each>

PS: Would be a good idea to rename the Folder variable to Folders (plural) - threw me off the track for a coouple of minutes :-)

Hi,

If I understand right, you need to get the ID of the GalleryFolder from within a nested for-each, right?

To do this I think the only way is to store what you need in a variable outside the second for-each:

<xsl:variable name="Folder" select="$currentPage/GalleryItem [not(umbracoNaviHide = 1 )]"/>
<xsl:for-each select="$Folder">
  <xsl:variable name="curGalleryItemId" select="$Folder/@id"/>
  <xsl:variable name="Images" select="umbraco.library:GetMedia(blaaahFolder, false())" />
  <xsl:for-each select="$Images">
    <a>
      <xsl:attribute name="href">
        <xsl:value-of select="umbraco.library:NiceUrl($curGalleryItemId)" />
      </xsl:attribute>
      <xsl:attribute name="target">_self</xsl:attribute>
      <img>
        ...         
      </img>
    </a>
  </xsl:for-each>
</xsl:for-each>

Hope this helps,
Tom

Thank you for your answers. I have now tried both, and it is still not working as I expect it to.

This is the output from <textarea><xsl:copy-of select="$Folders" />textarea> from within the for-each statement:

Please note that copy-of generates two textareas with the exact same content as below (there is a total of two GalleryItem entries).

<GalleryItem id="1192" parentID="1188" level="3" writerID="0" 
creatorID="0" nodeType="1185" template="1162" sortOrder="0" 
createDate="2011-09-30T18:35:12" updateDate="2011-10-12T00:56:25" 
nodeName="Første galleri" urlName="foerste-galleri" writerName="" 
creatorName="" path="-1,1164,1188,1192" isDoc="">
<metaDescription></metaDescription><metaKeywords></metaKeywords>
<bodyText> <p>Første galleri tekst.</p> </bodyText> 
<blaaah>1207</blaaah>
<blaaahFolder>1210</blaaahFolder></GalleryItem> 

<GalleryItem id="1193" parentID="1188" level="3" writerID="0" 
creatorID="0" nodeType="1185" template="1162" sortOrder="1" 
createDate="2011-09-30T18:50:55" updateDate="2011-10-12T02:08:22" 
nodeName="Andet galleri" urlName="andet-galleri" writerName="" 
creatorName="" path="-1,1164,1188,1193" isDoc="">
<metaDescription></metaDescription><metaKeywords></metaKeywords>
<bodyText> <p>Andet galleri tekst.</p></bodyText>
<blaaah>1200</blaaah>
<blaaahFolder>1206</blaaahFolder>
</GalleryItem>

The result from this is that the first id is selected for both gallery entries.

blaaah is the content (images) of a gallery entry (GalleryItem) and blaaahFolder is the selected image for the gallery listing (on currentPage).

Sorry guys, I think I was sleeping when trying to get this to work.

Sometimes it just helps to get away from the problem ;-)
